--- task: Check storage groups, units and history clients with hisdbg; force a rollover version: R1.05 (first written for R1.03) source: IM 36K10L20-01EN §2.1, §3.1 (4th Edition, Feb. 2026); IM 36K10C40-01EN §5.1 (5th Edition, Feb. 2026); practiced on the test system and CI-Eng-Sample 2026-10-01 status: verified on R1.03 (2026-10-01). R1.05 - the manual sections are unchanged and the hisdbg program is still installed (2026-10-08), but hisdbg was not run on the R1.05 test server (awaiting user verification, ISS-101; steps at the end) R1.05 (V6, 2026-10-09): hisdbg 1/20/6 and the start scripts verified read-only on the R1.05 test server. --- # History checks (`hisdbg`) Interactive; pipe the answers from bash with a timeout. The first answer is the node (blank = local), the last `-1` exits. Never send blank lines at the action prompt blindly (a blank repeats the previous action). ``` printf '\n1\n20\n6\n-1\n' | timeout 20 hisdbg printf '\n21\n\n3\n\n-1\n' | timeout 20 hisdbg ``` | Option | Shows | Safe | |---|---|---| | 1 | Statistics: group count, logged-in clients, unit starts / stops / rollovers / deletions since start | yes | | 20 | All groups: name, node,group number, history type (24 item, 21 alarm, 6 audit, 1058 report, 36 system log, 4 station statistics) | yes | | 21 `` | Group info: path, next unit and file name, opt_type (`1 1` Scan/Time, `2 2` Event/Item, `4 4` Aggregation), start, stop, first rollover, interval, life time (all GMT), GMT/LCT rollover, archiving | yes | | 3 (then blank = this group) | Units: unit, data, file, start, stop or `--- active ---`, delete time | yes | | 6 | Clients logged in at the history manager | yes | | 11 | Unknown history files | yes | | 5 | Force rollover of the current group (closes the active unit, starts the next) | changes files — with approval | | 4, 8, 10, 12, 9 | Delete unit / group, restore unit, delete unknown files, change schedule | **no — never without explicit approval** | A rollover can also be forced with `dssqld -m` on `HIS_GROUP_DF` (`NAME,FORCE_ROLLOVER` = `"",1`). A second forced rollover within 2 minutes is refused (`DSI-E-ROLLDONE, Rollover already done in the last two minutes`; verified 2026-10-01). History files are in `%TLS_ALLUSERS_PATH%\tls\his\` (path shown by option 21): `h.his` with base-32 digits, e.g. group 1,54 → `h0101m…`. ## What to look for - New group but no history: no active unit after loading → restart CI Server (ISS-006). - Unit start dates: the first unit of an Event/Item or Aggregation group is dated 2 days back (`gap_time`); history loaded before the first unit opened after the restart is dropped (see `storage-groups.md` §5). - After a CI Server restart the unit sequence increases (the start script runs `hisrep`). - Delete times = stop time + life time. ## Verified (R1.03, 2026-10-01) 45 groups, 30 clients; `CIENG_EVENT` group 1,54, opt_type `2 2`, daily GMT rollover, life 7 days; units 1,1 (created at load) → 3,1 after restart → forced rollover closed 3,1 at 12:05:26 and opened 3,2. `CIENG_SCAN10S` 1,55 `1 1`; `CIENG_AGG` 1,56 `4 4` with extra `h0101ozzz…` files. ## R1.05: awaiting user verification (ISS-101) On the R1.05 test server, in a normal command prompt (read-only options only): ``` hisdbg ``` Answer the node prompt with Enter (local), then `1` (statistics), `20` (all groups), `6` (clients), and `-1` to exit. Do not choose any other number. Expected: the same menu as R1.03 (`-1` … `22`), the system groups with history types 21, 6, 1058, 36, 4 (no item group unless the server has one), and clients such as ITH*, ALH, ADTSTO, LGHUMH, RPTMAN. Send the output. ## R1.05 test server (V6, 2026-10-09, read-only) - `hisdbg` options 1, 20 and 6 give the same prompts and layout as on R1.03 (menu −1…22): statistics, the group list with the system groups of history types 21 (ALH), 6 (ADT), 1058 (report groups), 36 (SYS_LOG), 4 (STATION_STAT) plus type 24 item groups, and the logged-in clients (DSSSDA*, RPTMAN, EQPIOSTAT, ALH, the ITH processes …). ISS-101 closed. - `history_start/stop.cmd` and `item_start/stop.cmd` differ from R1.03 only by the call of `?*_history_start.cmd` / `?*_item_start.cmd` (and the stop variants) extension scripts at the end (change i12719, ISS-121). The processes started are unchanged. ISS-100 closed.
