cliu 1c3558c37c Complete phase 1 and build the CI-Eng-Sample project 
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.

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.
