@@ -53,9 +53,30 @@ AIM uses Telerik OpenAccess connection pooling. Pool slots hold idle TCP connect
## Plan
### Tonight — scheduled service restart (low risk)
### Tonight — scheduled service restart (REGISTERED)
Restart `MSSQL$AIMSQL` at **02:30 AM MST on 2026-05-06** via a one-shot scheduled task on IMC1. Releases the paged-out working set, clears stale pool state, ~30 seconds of unavailability. RDP users with AIM open will need to relaunch in the morning. Expected to clear the immediate symptom for at least a week or two.
| Field | Value |
|---|---|
| Task name | `AIMSQL_Restart_20260506_0230` |
| Trigger | 2026-05-06 **02:30 AM MST** (one-shot) |
| Runs as | SYSTEM |
| Action | `powershell.exe -NoProfile -ExecutionPolicy Bypass -File "C:\Windows\Temp\aimsql-restart.ps1"` |
| Restart script path | `C:\Windows\Temp\aimsql-restart.ps1` (984 bytes) |
| Run log | `C:\Windows\Temp\aimsql-restart.log` (created on first run) |
| Auto-delete | none — manually remove after verifying clean run |
Script does: log pre-state → `Restart-Service "MSSQL$AIMSQL" -Force` → 15s sleep → log post-state → `SELECT 1, GETDATE()` via sqlcmd to confirm responsiveness → log result.
Quirks worth noting for future scheduled-task work on this server:
- `Register-ScheduledTask` rejected `-DeleteExpiredTaskAfter` on its own; it requires a trigger `EndBoundary`. Setting `EndBoundary` after the fact also returned "parameter is incorrect" on this Server 2016 box. Workaround: register without `DeleteExpiredTaskAfter` and clean up by hand. Worth saving as a recipe for future jobs.
- `schtasks.exe /Create` failed with "parameter is incorrect" — possibly the colon in the original task name (`... 02:30`) hit a path-vs-name validation. Switched to underscore-only name (`AIMSQL_Restart_20260506_0230`), which Register-ScheduledTask accepted cleanly.
### Morning verification (Howard, 2026-05-06 first thing)
1. Check `C:\Windows\Temp\aimsql-restart.log` via GuruRMM
2. Confirm SELECT 1 succeeded and AIMSQL post-state is Running
3. Sample-test AIM from a workstation if possible
4. Delete the scheduled task: `Unregister-ScheduledTask -TaskName AIMSQL_Restart_20260506_0230 -Confirm:$false`
