+  CI Server R1.03 high availability with HAC (redundant servers). Use when the user asks about
+  redundant / dual / triple / quad servers, primary and secondary server, active and standby,
+  switchover (automatic or manual), the HAC HMI (hacw_hmi), watchdog, recovery (restart a
+  process or tool, hacrec, -wdg_off), mirror / synchronization of the standby, journaling and
+  key file repair (isfjrn, *.jrn), history merge after an island situation (hachmfcmd), hac.sup,
+  CI_PRIM, hacw_standby / hacw_stop scripts, HAC status items (SYSTEM.HAC1), hacitmval, HAC
+  firewall ports (UDP 16000-16006), hardware watchdog or custom health checks, or applying a
+  patch to a redundant system. Source IM 36K10J20-01EN.

+
+# High availability — HAC (R1.03)
+
+Background: `knowledge/manuals/IM36K10J20-01EN.md` (concepts, processes, set-up steps,
+installed `hac.sup` and the differences from the manual).
+
+Rules:
+- Run `system-check` first; follow the user's chosen way of working.
+- HAC needs its own licence and at least two servers with two separate networks between them.
+  Nothing here was practiced on a real redundant pair: say so when giving procedures.
+- `hac.sup`, the `tls\com` scripts and system variables need admin rights and a restart; hand
+  them to the user (skill `portal-setup`, `change-setup-file.md`).
+- Never switch over, reboot or change a server's mode on a running plant without the user's
+  explicit approval, and only when the mirror is consistent (see `redundant-setup.md` §3).
+- Do not start `hacrec` with `-wdg_off` on a server without reviewing its process list first:
+  stand-alone Recovery acts (default action for most processes is `TOOL` = restart services).
+
+| Task | File | Status |
+|---|---|---|
+| Check HAC on a system: licence, processes, `hac.sup`, scripts, HMI properties, logs | `tasks/hac-checks.md` | verified (read-only, single server) |
+| Set up and operate a redundant server pair: steps, `hac.sup` tabs, manual switchover, patching | `tasks/redundant-setup.md` | from docs |
+| Recovery, logger and journaling on a stand-alone node | `tasks/standalone-recovery.md` | from docs |
+| Dual-redundant Platform for Computer | — | not covered (separate product) |

+task: Check HAC on a system (licence, processes, hac.sup, scripts, HMI properties, logs)
+version: R1.03
+source: IM 36K10J20-01EN §1.3–§1.5, §2, §4.1.4, §6.1; checked read-only on the test system 2026-10-01
+status: verified (read-only, single unlicensed server)
+---
+
+# HAC checks
+
+All read-only.
+
+## 1. Is HAC in use?
+
+| Check | Command / file | HAC in use when … |
+|---|---|---|
+| Licence | `dir %TLS_ROOT_PATH%\tls\sup\hacini.sup` | the file exists (licence files are `<tool>ini.sup`) |
+| Start script | `type %TLS_ROOT_PATH%\tls\com\ci_start.cmd` | it is a copy of `hacw_standby` (title *CI Server_in stand-by mode*, starts `haclog`, `lockmgr`, `isfjrn`) |
+| Server number | `echo %CI_PRIM%` | 0 primary, 1 secondary, 2, 3 |
+| Processes | `tasklist /FI "IMAGENAME eq hac*"` | `hacwdg`, `hacrec`, `haclog`, `hacmir`, `hacwagt`, `hacwitm` run |
+
+Test system (R1.03.00): no `hacini.sup`, normal `ci_start.cmd`, `CI_PRIM` unset, no `hac*`
+process — HAC not used.
+
+## 2. Configuration
+
+- `tls\sup\hac.sup`: read with the Setup File Editor or
+  `findstr /v /b "!" %TLS_ROOT_PATH%\tls\sup\hac.sup` (active lines only). Check `MODE`,
+  `HAC_HOSTS` (real host names, not `SERVER_A`…), `PRIMARY`/`SECONDARY` addresses, `IP_DEVICE`
+  (a real router/switch with priority 1; **no `localhost`** in production), `START_MANUAL`
+  (`NO` once commissioned), `RECOVERY_ON`, `JOURNAL_ON`, `HMF_DAYS`.
+  The installed file is a template (`SERVER_A`, `192.168.1.1`, `localhost`, `START_MANUAL =
+  YES`): if these are still present the pair was never configured.
+- `hac.sup` must be identical on all servers (it is excluded from the mirror on purpose).
+- HAC HMI: `%TLS_WAP_PATH%\cfg\jhacProperties\application.properties` — `primary=`,
+  `secondary=` (addresses of every network), `port1`/`port2` (16000), `logport` (16001).
+- Firewall: UDP 16000–16006, TCP 34489 (history merge), ICMP between the servers.
+
+## 3. State and logs (running pair)
+
+- HAC HMI: `hacw_hmi` (not in the start menu). Per server: responsive, operational status
+  (Standby / Activating / Active / Deactivating), mode (Automatic / Manual), CI Server / custom /
+  IP health, mirror mode and status (consistent = black text), recovery table, IP devices, log.
+- Status items if configured: `<section>.OPER_MODE` (87 manual, 88 automatic), `.OPER_STAT`
+  (95 active, 99 standby), `.CI_STAT`/`.IP_STAT` (90 healthy, 89 fault), `.DATA1_MODE`/
+  `.DATA1_STAT` (mirror) — read with `itmval -g`.
+- Logs: `%TLS_LST_PATH%\hac_log_<n>.txt` (cyclic; `hac_log_0.txt` names the current
+  page), `hacmir.log`/`hacmir_old.log` (mirror), `%TLS_LOG_PATH%\hacw_standby.log`,
+  `hacw_activate.log`, and `umhlog.log` (`HAC*`, `ISFJRN` messages; ISFJRN names the journal
+  report `<DSSSDA>_jrn.lst` after an unclean shutdown).
+- Watchdog start problems: `hacwdg -d` in a console shows initialization errors.

+version: R1.03
+source: IM 36K10J20-01EN §1.2–§1.5, §2.4–§2.6, §3, §4.3–§4.11, §6.4, §7; hac.sup and scripts checked on the test system 2026-10-01

+---
+
+# Redundant server pair (HAC)
+
+Everything here needs admin rights on both servers and a planned outage. Prepare the files;
+the user applies them.
+
+## 1. Preparation
+
+- Identical servers: same OS, CI Server version and patches, install path, TLS variables, node
+  number and licence (including HAC).
+- ≥ 2 separate network interfaces/segments between the servers (≤ 4), separate from field
+  networks if possible. One link only = single point of failure and the risk that both servers
+  go active.
+- Time sync on each server from an NTP/GPS source with jumps ≤ 1 s (not DUR time sync between
+  the pair: same node number).
+- At least one real IP device per server for the network check (router/switch, priority 1).
+- CI Service start type *Automatic* (HAC reboots servers).
+- `TLS_BACKUP_PATH` on a partition at least as large as `TLS_HIS_PATH` (the standby zips its
+  runtime environment before each synchronization; without the variable the scripts use
+  `TLS_LST_PATH`).
+
+## 2. Steps (on every server unless noted)
+
+1. System variable `CI_PRIM` = 0 (primary), 1 (secondary), 2, 3.
+2. Start CI Server once; create the optional status items per server (section, e.g.
+   `SYSTEM.HAC1`, items `OPER_MODE`, `OPER_STAT`, `CI_STAT`, `IP_STAT`, `DATA1_MODE`,
+   `DATA1_STAT`, …, all Integer); stop CI Server.
+3. `tls\com`: rename `ci_start.cmd`/`ci_stop.cmd` to e.g. `ci_start_old.cmd`/`ci_stop_old.cmd`,
+   copy `hacw_standby.cmd` → `ci_start.cmd`, `hacw_stop.cmd` → `ci_stop.cmd`.
+4. `hac.sup` on the primary (Setup File Editor), then copy to the others:
+
+| Tab | Set |
+|---|---|
+| General | `MODE` (DUAL/TRIPLE/QUAD), `HAC_HOSTS` (host names in priority order), `HAC_UNIT` (status item sections), `HEARTBEAT` |
+| Network | `PRIMARY`, `SECONDARY` … = the IP address of each network, same order on all servers |
+| Watchdog | `IP_DEVICE = <ip>, <label>, <timeout>, <retries>, <interval>, <priority>` (≤ 20; priority 1 = loss makes the server unhealthy; **remove the template `localhost` entry**), `WDG_CONNECT = <alive check s>, <timeout s>, <retries>, <max time diff s>, <inhibit s>`, `HARDWARE_WDG`, `CUSTOM` (script in `tls\com`, exit 0 = healthy), `START_MANUAL` |
+| Mirror (General) | `QUESIZE`, `MAXOPNDB`, timeouts, `MAX_ACTIONS`, `LOG_FILE_SIZE` — defaults normally fine |
+| Mirror (Working set) | `INCLUDE_DIR`/`EXCLUDE_DIR`/`EXCLUDE_FILE`; keep the default excludes (node-private files such as `durm*.sup`, `*ini.sup`, `hac.sup`) |
+| Recovery (General) | `RECOVERY_ON = YES` (required: it reports CI Server health to the Watchdog), `START_DELAY`, `TOOL` hierarchy, `PROCESS` list (remove unlicensed processes; add `HACMIR2`/`HACMIR3` for TRIPLE/QUAD), `NO_RUN`, `STANDBY` |
+| Recovery (Monitoring) | `MAX_QUEUE`, `MAX_CPU`, `INACTIVE` (none set in the installed file) |
+| Recovery (Custom actions) | `ACTION = <id>, <command>, <delay>, <params>` |
+| History merge | `HMF_DAYS` (0 = off), `HMF_PATH` (outside the mirror, ~3 × period of history), `HMF_PORT` (34489) |
+| Other | `JOURNAL_ON` (only small systems; needs write cache off), log size/pages/level, `PORTNUMS` (also change the `hacwsck` lines in the `hacw_*` scripts and the HMI properties) |
+
+5. HAC HMI properties (`%TLS_WAP_PATH%\cfg\jhacProperties\application.properties`) on every
+   machine that runs the HMI: `primary=`, `secondary=` addresses.
+6. Firewall: UDP 16000 (GUI/commands), 16003 (recovery), 16004 (watchdog↔watchdog), 16005 (item
+   setter), 16006 (file copy slave) between servers/HMI stations; 16001/16002 local; TCP 34489;
+   ICMP.
+7. Start both servers; both come up STANDBY, the primary goes ACTIVE (if not in manual mode).
+   Test switchovers, then set `START_MANUAL = NO` so they start in AUTOMATIC.
+
+## 3. Operating
+
+- Manual switchover (HAC HMI): only when the mirror is consistent (active = master/active,
+  standby = slave/standby, black text) and at least one LAN is good. Set the ACTIVE server to
+  MANUAL and the STANDBY to AUTOMATIC, then change the ACTIVE server's status to STANDBY.
+- Short maintenance on the active server: set all servers MANUAL (no automatic switchover),
+  restart what is needed, set back to AUTOMATIC. Status changes are refused in AUTOMATIC mode.
+- No automatic switch-back to the primary after it recovers.
+- Both servers active (HAC network lost): before reconnecting, put the server that should
+  become standby into standby by hand; then the active one synchronizes it. Use history merge
+  (`hachmfcmd` on the active server) to recover event history from the other server.
+- Monitoring the standby from the active side: `hacitmval -c <active host> -n <section>.<item>
+  -v <int>` on the standby (the section must be one of the status item sections).
+
+## 4. Patching a redundant pair (§6.4)
+
+1. Full backup. 2. Stop the standby for maintenance (set it MANUAL, stop CI Server, set
+`START_MANUAL = YES`). 3. Patch it. 4. Start it in manual; wait until the mirror shows master
+active / slave standby. 5. Manual switchover to it. 6. Stop and patch the old active server.
+7. Start it in manual (it becomes standby). 8. Set both to AUTOMATIC and `START_MANUAL = NO`.
+Patches change files outside the mirror (`exe`, common files), so they are never copied
+automatically.
+
+## 5. Tips (§4.8, §6.5, §7)
+
+- Large history: synchronization backups take long (ZIP of `TLS_HIS_PATH`); the manual's
+  options are to zip only the `*000000.*` administration files in `hacm_create_backup` /
+  `hacm_restore_backup` (history data then not protected) or use another archiver.
+- Increase the Watchdog inhibit time on big systems so a fresh standby is synchronized before
+  another switchover is allowed; increase *Data to master* timeout if big key-file repairs on
+  the slave restart the synchronization.
+- CI Server must start within 5 minutes, otherwise the servers keep switching.

+task: Use HAC Recovery, logger and journaling on a stand-alone node

+
+# HAC on a stand-alone node
+
+Without a redundant pair, two HAC functions are still useful on any node: **Recovery** (restart
+or report unhealthy CI Server processes) and **journaling** (repair after an unclean shutdown).
+Admin rights and a restart are needed; hand the changes to the user.
+
+## 1. Recovery and logger
+
+1. In `tls\com\integration_start.cmd` uncomment the HAC block:
+   ```
+   start /B /NORMAL %TLS_ROOT_PATH%\tls\exe\haclog.exe > nul
+   start /B /NORMAL %TLS_ROOT_PATH%\tls\exe\hacrec.exe -wdg_off > nul
+   start /B /NORMAL /WAIT %TLS_ROOT_PATH%\tls\exe\durwfp -p hacrec -t 10
+   ```
+   and the matching stop lines in `integration_stop.cmd`. `-wdg_off` = no Watchdog: Recovery
+   acts itself.
+2. **Review `hac.sup` first** (tab *Recovery (General)*): the installed list has ~70 `PROCESS`
+   lines, most with action `TOOL` (restart the tool and everything that depends on it), for
+   processes that may not run on your node (e.g. `HASEXE`, `ITHEEX`, `DSSSDA00`–`03`, PROCESS
+   executors). Remove what does not run there (an HMI node keeps only BUS, DATABASE and COLOUR
+   processes), list optional processes under `NO_RUN`, and prefer `ALERT` (message in
+   `umhlog.log`) until you are sure a restart is wanted. `REBOOT`/`SHUTDOWN` call
+   `tls\com\hac_reboot`/`hac_shutdown`, which are not shipped (copy `hacw_shutdown` if needed).
+3. Optional checks (tab *Recovery (Monitoring)*): `MAX_QUEUE`/`MAX_CPU` (average % over a
+   period ≥ 10 s; the process must also be in `INACTIVE`) and `INACTIVE` (heartbeat-based
+   non-response, only processes that support it). None are set in the installed file.
+4. `START_DELAY` (30 s) is also the pause after each recovery action; raise it to minutes with
+   `ALERT` to avoid repeated messages.
+5. Read the result in `%TLS_LST_PATH%\hac_log_<n>.txt` (or the HAC HMI *Log* tab) and
+   `umhlog.log`.
+
+Project processes: start them from `integration_start` (or a `<tool>_start`/`<tool>_stop` pair
+plus a `TOOL` line), then add `PROCESS = <name>, <tool>, <action>`; a trailing `*` is the only
+wildcard (`EQP*`).
+
+## 2. Journaling
+
+1. `hac.sup` tab *Other*: `JOURNAL_ON = YES` (heavy disk load — small systems only).
+2. Disable the disk write cache for the `TLS_DAT_PATH`/`TLS_HIS_PATH` disks (Device Manager ›
+   disk › *Policies*) or use a UPS; optionally enable `ismflush <disk> <s>` in
+   `tls\com\database_start.cmd` (commented example `ismflush.exe \\.\C: 60`).
+3. After an unclean shutdown: ISAM key files are repaired automatically at start (`ISFJRN`);
+   for datasets read the report named in `umhlog.log` (`tls\lst\<DSSSDA>_jrn.lst`) and run the
+   listed `dsschk -d <set>` / `dsschk -r <set>` (back up first; skill `system-management`,
+   `consistency-check.md`).
+4. After restoring a backup, delete `%TLS_DAT_PATH%\*.jrn` so no false repairs run.
+
+## 3. Related monitoring
+
+For whole-system CPU, disk, TCP and DURM link checks use the INTEGRATION monitors (`intcpumon`,
+`intdskmon`, `inttcpmon`, `intmon`): skill `system-management`, `monitoring-processes.md`.

+task: Active Directory integration and single sign-on (SPNEGO) for CI Server
+version: R1.03
+source: IM 36K10J40-01EN §1–§3, App. 1; dssana.sup AD/SSO keywords and auth\WEB-INF templates checked on the test system 2026-10-01
+status: from docs (no domain on the test system)
+---
+
+# Active Directory and single sign-on
+
+Needs a Windows domain, domain-joined CI Server machines and admin rights on the machines and
+the domain controller. Not practiced; give the procedure and prepare the setup-file changes,
+the user (and the domain administrator) applies them. Details: `knowledge/manuals/IM36K10J40-01EN.md`.
+
+## 1. Decide the mapping mode
+
+| | `Security_group` (recommended) | `Organizational_unit` (default in the file) |
+|---|---|---|
+| CI Server side | Each user profile gets a *Directory group* (Engineering Module user form, tab *Directory Services*; `USER_DF.DIRECTORY_GROUP`) and a *Profile priority* (`MERGE_PRIORITY`) | User profile names = OU names |
+| AD side | One security group per profile, same name as the directory group; users in the groups | One OU per profile containing the users; all users also in the group named in `AD_SEC_GRP` (default: group named like the CI Server node) |
+
+Profiles: reuse CI Server users as roles (e.g. `ADMIN`, `ENG`, `OPER`, `<Section>` operators);
+they need no password for AD logins. A user in several groups gets the highest priority profile.
+
+## 2. Enable AD integration (CI Core / CI Portal)
+
+Prepared `dssana.sup` lines (tab *Active Directory*):
+
+```
+AD_INT_ON
+AD_MAP_MODE = Security_group
+AD_CHECK_THRESHOLD = 30
+```
+
+Optional (installed keywords, not in the manual): `AD_SERVER = "<dc host>[:port]"`,
+`AD_SERVER_BACKUP`, `AD_SECURE` (LDAPS, port 636), `AD_ACCESS_USER`/`AD_ACCESS_PASSWORD` (blank =
+the account that runs CI Server). For OU mode set `AD_MAP_MODE = Organizational_unit` and
+`AD_SEC_GRP = "<group>"`.
+
+Then: join the machine to the domain; run the CI Service as a domain account that is a local
+administrator (*Services › CI Server Service › Log On*); restart CI Server. Users log in as
+`<domain>\<user>` or `<user>@<domain>`; the Edit/Engineering Module login methods are then
+ignored. If web access must not be open to every domain user, disable CI Portal (port 0 in
+`jwuiisg.sup`, *Client communication*) — the manual's own warning.
+
+## 3. Single sign-on for remote CI View (SPNEGO)
+
+Checklist (order matters):
+1. DNS forward and reverse records for CI Portal and CI View; CI Portal reached by host name;
+   CI Portal with a valid SSL certificate (skill `portal-setup`).
+2. DC: service user (e.g. `sso`), `setspn -S http/<portal FQDN> sso`, `ktpass … -out
+   <file>.keytab -princ http/<portal FQDN>@<REALM> …` (realm upper case), delegation trust.
+3. Keytab to `%TLS_ALLUSERS_PATH%\wap\webapps\auth\WEB-INF`; `kinit http/<portal
+   FQDN>@<REALM>` succeeds on CI Portal (`tls\jre\bin`) and CI View (Remote Connect JRE).
+4. `dssana.sup` tab *Single Sign On*: `SSO_INT_ON`, `WEBHMI_SERVER_FQDN = "<portal FQDN>"`,
+   `DOMAIN_NAME = "<REALM>"`, `KRB5_FILE = "<path>\krb5.ini"` (set the realm mapping in that
+   file), `KEYTAB_FILE = "<file>.keytab"`, `SSO_TOKEN_DURATION` (s); restart USER Service.
+5. Browsers on CI View: Firefox `network.negotiate-auth.trusted-uris` and `…delegation-uris`
+   = `https://<portal FQDN>`; Edge/IE: add the site to *Local intranet*, integrated Windows
+   authentication on.
+6. Test: temporarily enable the `test` servlet in `web.xml`, open
+   `https://<portal FQDN>:8443/auth/test`, expect *Authorization scheme : SPNEGO*; restore
+   `web.xml`.
+7. Start applications from the *Remote Connect* folder on CI View; the login methods `SSO` in
+   *Login control* (installed default for most UIs) then log the user in without a prompt.
+
+Common failures (manual): "realm not found" → fix `krb5.ini`; access by IP address or from the
+CI Portal machine itself → no SPNEGO; DNS reverse lookup missing → ticket errors.

+task: Read and change login methods per client and user interface (dssana.sup Login control)
+version: R1.03
+source: IM 36K10C10-01EN §2.2; IM 36K10J40-01EN §1.1, §2.10.3; dssana.sup help and installed values checked on the test system 2026-10-01
+status: verified (reading and the No-login behaviour; changing the file from docs — admin)
+---
+
+# Login methods (`dssana.sup`, tab *Login control*)
+
+## 1. Read the current methods
+
+`findstr /b LOGIN_METHOD %TLS_ROOT_PATH%\tls\sup\dssana.sup` (or the Setup File Editor).
+
+```
+LOGIN_METHOD = <client>, "<user interface>", <method>, <no login when no users>, "<no-login profile>"
+```
+
+- `<client>`: host name or IP (wildcards allowed), `"<local>"` (this machine) or `"<remote>"`
+  (any other); lines are evaluated top-down, `<local>`/`<remote>` always last.
+- `<user interface>`: the full name from the *User Interfaces* tab (`USER_INTERFACE = …`), e.g.
+  `"Engineering Module"`, `"Edit Module"`, `"Operator Interface"`, `"Quickload Utility"`.
+- `<method>`: `Automatic` (Windows name = CI Server user, no password), `Manual CI Server`,
+  `Manual OS`, `No`, `SSO`, `Deny`.
+
+Installed (R1.03.00): local and remote Engineering Module, Edit Module, Operator Interface, Item
+Search, Mobile Operator, Excel Add-in → `SSO` (falls back to *Manual CI Server* while SSO is not
+set up); local Quickload / Display and Symbol Utility → `No`; remote Playback Viewer, Quickload,
+Display/Symbol utilities → `Deny`; OPC UA server, ODBC, `dnetapi` → `Manual CI Server`;
+anonymous OPC UA (local) → `No` with profile `CI_NO_LOGIN_OPCUAS`.
+
+## 2. *No* login — check the profile
+
+With `No` the user interface runs with the no-login profile (5th field). **If no CI Server user
+with that name exists, the session gets full authorization** (`dssana.sup` help; verified
+indirectly: `Quickload Utility` uses `No` with an empty profile and every `dssqld` change is
+recorded in the audit trail as user `FULL AUTHORIZATION`). The installed lines name
+`CI_NO_LOGIN`, which does not exist by default (only `CI_NO_LOGIN_OPCUAS` does).
+
+Before setting `No` for an operator UI: create user `CI_NO_LOGIN` with a restricted
+authorization group (`users-groups.md`) and a password, then change the method.
+
+## 3. Change a method
+
+Admin rights; hand to the user (skill `portal-setup`, `change-setup-file.md`). Add a specific
+line above the `<local>`/`<remote>` lines (e.g. one HMI PC by host name), save, restart USER
+Service (or CI Server) for it to take effect. With **AD integration on** (`AD_INT_ON = YES`) the
+methods of the Edit and Engineering Modules are ignored: see `active-directory.md`.

+edition: 3rd Edition, Sep. 2023
+version: R1.03
+status: installed hac.sup, hacw_*/hacm_* scripts, HAC executables, HAC HMI properties and integration_start checked read-only on the test system 2026-10-01; redundancy, mirror, journaling, recovery and history merge from docs only (single unlicensed server, HAC not licensed)
+---
+
+# High Availability Computing — HAC (R1.03)
+
+CI Server offers two high-availability options: **HAC** (active/standby servers, this manual)
+and the Dual-redundant Platform for Computer (not covered). HAC is part of DATABASE Service,
+installed on every node, but needs its own licence. Configuration is in `tls\sup\hac.sup`.
+Section numbers refer to the manual; "installed" means checked on the R1.03.00 test system.
+
+## 1. Concepts (§1.1, §3.1)
+
+- **ACTIVE / STANDBY**: only one server runs CI Server completely; the standby runs a minimal
+  set (BUS, lock manager, HAC processes) and watches its partner. All servers start as
+  STANDBY; the highest-priority healthy one goes active.
+- **PRIMARY … QUATERNARY**: physical machines, in priority order (DUAL, TRIPLE, QUAD). The
+  primary only matters at start-up: after a switchover the system does **not** switch back.
+- **AUTOMATIC / MANUAL** per server: in MANUAL the server still checks health but takes no
+  action; no switchover to or from a MANUAL server. Use MANUAL for engineering and maintenance.
+- Same CI Server node number on all servers, different IP addresses; clients do not see which
+  machine is active. Switchover takes some tens of seconds after a fault is detected.
+- **Island**: a server with no partner and no IP device reachable shuts itself down;
+  otherwise the active server is shut down by its partner, not by itself.
+
+## 2. Parts (§3)
+
+| Function | Process | Job |
+|---|---|---|
+| Watchdog | `HACWDG` | Decides health from Recovery, partner link, IP devices (≤ 20, ping) and custom scripts; switches over; hardware-watchdog keep-alive script |
+| Recovery | `HACREC` | Watches CI Server processes (running, DUR queue %, CPU %, non-responsive heartbeat). With a Watchdog it only reports; stand-alone (`-wdg_off`) it acts: ALERT, PROCESS, TOOL (restart tool and its dependants in hierarchy order), REBOOT, SHUTDOWN |
+| Mirror | `HACMIR1` (+ `HACMIR2/3` for TRIPLE/QUAD), `HACMIRSLV`, `HACWAGT` | Keeps the standby in sync: zip backup of the standby first (`TLS_BACKUP_PATH`), then file comparison, then event-based ISAM record changes and file-change watching |
+| Journaling | `ISFJRN` (start-up), DSS journal | Tracks open ISAM files (key file repaired automatically at start) and open datasets (report `<DSSSDA>_jrn.lst` in `tls\lst`, repair by hand with `dsschk -r`) |
+| Logger | `HACLOG` | Cyclic text log `tls\lst\hac_log_<n>.txt`; `hac_log_0.txt` names the current page |
+| Item setter | `HACWITM`, `hacitmval` | Standby server writes items on the active server (`hacitmval -c <host> -n <item> -v <int> [-s <status>]`; the section must be a status item location) |
+| History merge | `hachmf*` | After an island period, copies event history of the secondary and merges it into the primary for OFFLINE periods (`HMF_DAYS` 0 = off; `hachmfcmd`) |
+| HMI | `hacw_hmi` (Java) | Server states, LAN links, mode/status dialogs, recovery table, IP devices, log; reads `%TLS_WAP_PATH%\cfg\jhacProperties\application.properties` |
+
+Status items (optional, created by the engineer, one section per server, e.g. `SYSTEM.HAC1`):
+`OPER_MODE`, `OPER_STAT`, `CI_STAT`, `IP_STAT`, `DATA1–3_MODE`, `DATA1–3_STAT` with codes such as
+87 manual, 88 automatic, 95 active, 99 standby, 89 fault, 90 healthy, 85/86 mirror master/slave.
+
+## 3. Setting up a redundant pair (§1.2, §1.3)
+
+1. Two (or more) identical servers, same install path and TLS variables, same node number and
+   licence; **at least two separate networks** between them (≤ 4); time sync with ≤ 1 s jumps
+   (DUR time sync cannot be used between the servers: same node number); CI Service start
+   type *Automatic* (HAC reboots servers).
+2. System variable `CI_PRIM` = 0 primary, 1 secondary, 2, 3.
+3. Start CI Server once, create the status items, stop.
+4. In `tls\com`: rename `ci_start`/`ci_stop` (keep copies), copy `hacw_standby` → `ci_start`,
+   `hacw_stop` → `ci_stop`.
+5. `hac.sup` on the primary, then copy to the others: mode, host names, status item sections
+   (*General*); IP addresses per network (*Network*); IP devices (at least one real device;
+   remove `localhost` after testing), partner alive check (*Watchdog*); mirror tabs; recovery
+   (remove unlicensed processes; add `HACMIR2/3` for TRIPLE/QUAD); journaling (*Other*).
+6. HAC HMI properties: `primary=`/`secondary=` addresses, ports.
+7. Firewall: UDP 16000–16006 as listed in §1.3, TCP 34489 (history merge), ICMP.
+8. When tested: clear *Start in manual mode* so the servers start in AUTOMATIC.
+
+Manual switchover (§2.6): set the active server MANUAL and the standby AUTOMATIC in the HAC HMI,
+then set the active server's status to STANDBY. Only when the mirror is consistent (active =
+master/active, standby = slave/standby, text black in the HMI) and at least one LAN is good.
+Repair scenarios and patch installation (standby first, switch over, then the old active):
+§6.4.
+
+## 4. Stand-alone use (§4.1)
+
+On any node HAC can run without a Watchdog: Recovery (`hacrec -wdg_off`) and the logger. The
+lines are in `tls\com\integration_start.cmd`, commented out. Recovery then **acts** on
+problems; review the process list (e.g. remove tools that do not run on an HMI node) and keep
+actions at ALERT unless a restart is really wanted. Journaling also works stand-alone (needs
+write cache off on the data/history disks, §4.9, and `ismflush` in `database_start.cmd`).

+title: Active Directory Integration
+edition: 3rd Edition, Sep. 2023
+version: R1.03
+status: installed dssana.sup (Active Directory, Single Sign On and Login control tabs), USER_DF fields and the auth WEB-INF templates checked read-only on the test system 2026-10-01; AD and SPNEGO set-up from docs only (no domain)
+---
+
+# Active Directory Integration (R1.03)
+
+With AD integration CI Server takes users from a Windows domain (Kerberos/AD) instead of its own
+user list; with single sign-on (SPNEGO) remote CI View users start CI Portal applications without
+a login dialog. Windows only. Section numbers refer to the manual; "installed" means checked on
+the R1.03.00 test system.
+
+## 1. What it gives (§1)
+
+Users and policies kept in one place (the domain), no second login after Windows, strong
+password rules from Windows, still works when the domain controller is unreachable (cached
+profiles), switchable per CI Server system. No *secondary login* (temporary elevation) with
+AD/SSO. AD integration **overrides** the per-application login methods in `dssana.sup`.
+
+Prerequisites (§2.1): CI Server machines in a valid AD domain, .NET 3.5+, domain users, and the
+CI Service started by a domain user that is a local administrator (§2.12: add the AD user to
+the local *Administrators* group, then *Services › CI Server Service › Log On* with that account).
+
+## 2. Mapping AD users to CI Server user profiles (§2.4–§2.7)
+
+The CI Server user records (`USER_DF`, Engineering Module user profile form) act as **profiles**;
+AD users need no CI Server password. Two mapping modes (`AD_MAP_MODE`, one only):
+
+| Mode | How a user gets a profile |
+|---|---|
+| `Organizational_unit` (default) | The user's AD **OU** name = CI Server user name; the user must also be in the AD security group named in `AD_SEC_GRP` (`"use_default_node_name"` = a group named like the CI Server node) |
+| `Security_group` (**recommended**) | The CI Server user's *Directory group* (`USER_DF.DIRECTORY_GROUP`, tab *Directory Services*) = an AD security group name, e.g. `ADMIN` ↔ `FT-ADMIN-GR`, `ENG` ↔ `FT-ENG-GR`, `OPER` ↔ `FT-OPER-GR`. Several memberships: the highest *Profile priority* (`MERGE_PRIORITY`) wins; equal priority → first in alphabetical order. Nested groups count |
+
+`ADMINE` is the enterprise profile (Enterprise Automation System only). When AD is enabled the
+`ADMIN` profile is the default.
+
+## 3. Setup steps (§2.8–§2.12)
+
+1. IP addresses and DNS (AD server as preferred DNS) on the domain controller, CI Portal/Core
+   and CI View machines.
+2. Domain controller: AD DS role, promote to DC (new forest), DNS forward **and reverse**
+   lookup zones with A and PTR records for CI Portal and CI View (`nslookup` to verify).
+3. *Active Directory Users and Computers*: an OU for the CI Server objects (example
+   `SCADAGROUP`), then OUs + one security group (OU mode) or security groups (group mode), the
+   users, memberships.
+4. `dssana.sup` tab *Active Directory* on CI Core/Portal: enable, mapping mode, security group
+   (OU mode only), check threshold. Restart USER Service.
+5. Join CI Portal/Core to the domain; users log in as `<domain>\<user>` or `<user>@<domain>`.
+6. When AD is on, the login methods of the Edit and Engineering Modules are ignored and no login
+   dialog appears; access depends on the mapped profile's rights. **Security note** in the
+   manual: anyone with a domain account can then use CI Portal; set the CI Portal port to 0 in
+   `jwuiisg.sup` (*Client communication*) if web access is not wanted.
+
+## 4. Single sign-on for CI View (SPNEGO, §3)
+
+Prerequisites: AD integration on, valid CI Server profile for the domain user, CI Portal with a
+valid SSL certificate, CI View in the intranet zone, CI Portal addressed by host name with
+forward and reverse DNS, browser integrated Windows authentication, CI View not on the CI
+Portal machine.
+
+1. DC: a dedicated AD user (e.g. `sso`, password never expires), `setspn -S
+   http/<portal FQDN> <user>`, `ktpass -out <file>.keytab -princ http/<portal FQDN>@<REALM>
+   -mapuser <user> -mapOp set -pass <password> -crypto All -ptype KRB5_NT_PRINCIPAL` (realm in
+   upper case; one SPN per CI Portal), *Trust this user for delegation* (Kerberos only).
+2. Copy the keytab to `%TLS_ALLUSERS_PATH%\wap\webapps\auth\WEB-INF`; check with `setspn -L`.
+3. `kinit http/<portal FQDN>@<REALM>` from `tls\jre\bin` on CI Portal and from the Remote
+   Connect JRE on CI View (must succeed).
+4. `dssana.sup` tab *Single Sign On*: CI Portal FQDN, SPN domain, `krb5.ini` path (realm
+   mapping; template in `auth\WEB-INF`), keytab file name, token duration. Restart USER Service
+   (generates the `*.conf` files).
+5. Browser: Firefox `network.negotiate-auth.trusted-uris`/`delegation-uris`; IE/Edge intranet
+   sites + integrated Windows authentication.
+6. Test page: uncomment the `test` servlet in `web.xml`, restart, open
+   `https://<portal FQDN>:8443/auth/test` → *Authorization scheme : SPNEGO*; restore `web.xml`.
+7. CI View: start applications from the *Remote Connect* start-menu folder; no login prompt,
+   the loaded profile shows in the status bar.
+
+## 5. Installed (R1.03.00 test system)
+
+- `dssana.sup` *Active Directory* tab keywords: `AD_INT_ON` (installed `NO`), `AD_SECURE`
+  (`NO`; help: "default is yes"), `AD_SERVER`, `AD_SERVER_BACKUP` (host or IP, optional
+  `:port`; 389 plain, 636 secure), `AD_ACCESS_USER`/`AD_ACCESS_PASSWORD` (blank = the account
+  that runs CI Server), `AD_MAP_MODE` (`Organizational_unit`), `AD_SEC_GRP`
+  (`"use_default_node_name"`), `AD_CHECK_THRESHOLD` (30 s). The server, secure and access-user
+  keywords are **not in the manual** (ISS-054).
+- *Single Sign On* tab: `SSO_INT_ON` (`NO`), `SSO_TOKEN_DURATION` (20 s),
+  `WEBHMI_SERVER_FQDN` (`'my-host.some.domain'`), `DOMAIN_NAME` (`SOME.DOMAIN`), `KRB5_FILE`,
+  `KEYTAB_FILE` (`'keytab'`) — placeholders.
+- `%TLS_WAP_PATH%\webapps\auth\WEB-INF` holds `krb5.ini`, `readme.txt` and the templates
+  `spnego.conf.tpl`, `spnego.properties.tpl`, `web.xml.tpl`, `webstartauth.conf.tpl`.
+- `USER_DF` has `DIRECTORY_GROUP` (68 characters) and `MERGE_PRIORITY` (the manual's *Profile
+  priority*).
+- *Login control*: the installed lines use **SSO** for local and remote Engineering Module, Edit
+  Module, Operator Interface and other UIs; without SSO set up this falls back to *Manual CI
+  Server* (help text). The *No* login profile is `CI_NO_LOGIN` (anonymous OPC UA:
+  `CI_NO_LOGIN_OPCUAS`); help: if no user with that name exists, **full authorization** is used.
+  Verified indirectly: `Quickload Utility` has *No* login with an empty profile and every
+  `dssqld` run is recorded as user `FULL AUTHORIZATION` in the audit trail (ISS-018).
+
+Task files: skill `authorization` (`login-methods.md`, `active-directory.md`).

 | ISS-021 | 2026-09-30 | EQUIPMENT (`eqpiostat`) | IM 36K10L40 §2 says `eqpiostat` stores hourly I/O statistics per station line in "history group STATION_STAT". On the test system `eqpiostat` runs (started by `equipment_start.cmd` on the host node) and `STATION_STAT` is a dataset, but `dssqld -e` returned 0 records, also with filters on `TIME_STAMP` and `STATION` (AID Modbus stations, which send requests). | closed | Answered 2026-10-01: with `CIENG_PLC` communicating (Modbus slave mirror running), `STATION_STAT` holds one record per hour per station line (10 records since 30-09-2026 18:00; e.g. `TIMESPAN` 831 s, `SENDS`/`GOODANS` 1560/1560, no errors). The earlier empty export had no communicating station. Closed 2026-10-01 (confirmed by user). | `knowledge/manuals/IM36K10L40-01EN.md` §2 |

 | ISS-050 | 2026-10-01 | AUDIT (classifier `STORAGE`) | Setting `AUDIT_EVENT_CLAS_DF.STORAGE` = 0 for `DATASET.NULL-ATTR.MODIFY.ENT-ENG-MOD` at 17:01:12 did not stop the next `dssqld -m ITEM_VAL` change from being stored (17:01:12.573). IM 36K10L25 §3.2 explains a per-process cache refreshed every `ECL_REFRESH` s (default 1800); the notifier here is `DSSSDA`, so the change should apply within 30 minutes. | closed | Re-tested: at 17:32:18 (after the 30-minute refresh) the same change was **not** stored, so the flag works with a delay. Set back to 1 at 17:32; the next change was still not stored (the cache works in both directions). Documented: allow up to `ECL_REFRESH` (1800 s) or restart CI Server. Close when the user confirms.

 | ISS-051 | 2026-10-01 | AUDIT (manual vs installed) | Differences between IM 36K10L25 and R1.03.00: (1) App. 1 lists subject `F/T-SYSTEM`, the installed classifiers use `CI-SERVER` (logins) and also `EAL OPERATION` (subject and action) and source `VIA-OPC-UAS`, not in the manual; 463 classifiers installed. (2) App. 1 explanations of `SHELVE` and `UN-SHELVE` are swapped. (3) `QUESIZE`: manual default and maximum 200 kB, `adtsys.sup` help default 10 kB, minimum 10 (file sets 200). (4) `TIMEFMT` default: manual `DD/MM/YY hh:mm:ss.ppp`, `adtsys.sup` help without `.ppp`; `ADTLOG` output shows milliseconds (manual right). (5) `dssqld` changes are recorded with source `ENT-ENG-MOD`, not `QUICKLOAD`. (6) The selection expression language is not described in the manual; the compiler listing gives the words and operators (no `LIKE`). (7) `ADT` group lifetime 52 weeks on the test system vs 2 days default when `ADTSTO` creates it (§2.1.1). | closed | Documented in the L25 summary and the `audit-trail` skill.

 | ISS-052 | 2026-10-01 | GRAPHICS (stale item id) | The HTML display `CIENG_Tank` showed **0** in its number field on `CI-Eng-Sample.TANK1.LEVEL` (live value 50) and the popup `ITM-E-NO_MAIN, No main item found`, in a fresh session after a CI Server restart. The display XML stores `<itemName>` **and** `<itemId>1.1.268.0.0.1.1.7</itemId>` from when it was built; after today's sample reloads the item has `ID_NUMBER` 357. Phase 10 had seen live values after a reload, so the id is not always used, but here it broke the field. | closed | Fixed in the sample: removed the `<itemId>` line from `displays/CIENG_Tank.xml`, redeployed; the field shows 50 and the popup is gone (binding by name).
