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.

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.

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.
