Add verified system-management tasks (item read/write, quick load records, history load, monitoring processes, consistency check, tuning checks), the importable CI-Eng-Sample project with load/remove scripts, the unlicensed 1-hour shutdown note, and the sample-project re-test rule. Close ISS-002/003/004 and log ISS-005..007. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

# Tuning checks (read-only)
|
|
|
|
Checks whether CI Server needs tuning. Nothing here changes the system. Changing the limits
|
|
means editing setup files and restarting CI Server: ask the user first.
|
|
|
|
## Limits in setup files (`%TLS_ROOT_PATH%\tls\sup\`)
|
|
|
|
Read the active (non-`!`) lines:
|
|
|
|
| File | Keyword | Meaning | Test system |
|
|
|---|---|---|---|
|
|
| `dur.sup` | `dur_max_proc` | Max processes (default 250) | 250 |
|
|
| `dur.sup` | `pool_kbytes` | DUR message pool | 250000 |
|
|
| `itm.sup` | `pool_kbytes` | Item common memory pool | 650000 |
|
|
| `database_start.cmd` (`tls\com`) | `-u` / `-f` | Max database users (default 2K) / files (default 1,200) | not checked |
|
|
|
|
## Live values: automatic health snapshots
|
|
|
|
CI Server's system monitor (`smdmon`) writes debugger snapshots about every 10 minutes to
|
|
`%TLS_LOG_PATH%\smd_<node>_<debugger>_*.log` (e.g. `smd_UNLICENCED_LOW_itmdbg_all.log`).
|

Read the newest entries:
|
|
|
|
| File | What to check | Target (IM 36K10J10 §5.5.1) |
|
|
|---|---|---|
|
|
| `*_itmdbg_all.log` | `common size` / `free size` | Free above 10 %, usage below 75 % |
|
|
| `*_smdsnp_process.log` | Per process: `queue_size`, `queue_used`, `queue_high` | No requests waiting (`queue_used` 0); enlarge a queue that stays in use |
|
|
| `*_ismdbg_all.log` | `Total number of lock collisions`, users, files | Collisions not rising above 250/s; entries below 80 % of max users |
|
|
| `*_smdsnp_process.log` | Number of processes | Well below `dur_max_proc` |
|
|
|
|
Test system (2026-09-30): common memory 665.6 MB, free 665.3 MB; queues empty; 3 lock
|
|
collisions in total.
