Before vs. After Diagnostic Results
Before Asynchronous Audit
- CPU Utilization: 100% Constant Spike
- Database Wait Events: latch: row cache objects (420s max duration)
- Database Errors:
ORA-08102: index key not found - Business Impact: Full Portal Outage during Enrollment
After DBPros Audit Implementation
- CPU Utilization: 22% Nominal Load
- Database Wait Events: < 0.05s average wait
- Database Errors:
Zero ORA errors recorded - Business Impact: 100% Uptime across Registration Window
The Asynchronous Resolution Workflow
Local Log Sanitization & Bundle Creation
The university DBA team downloaded the open-source DBPros collector script and ran it locally. Internal IP addresses (192.168.x.x), server FQDNs, and database credentials were masked automatically to comply with university FERPA data policies.
AI-Assisted Diagnostic Analysis (Async)
Within 24 hours of log upload, DBPros identified row cache latch contention on index PS_JOB_RUN_CNTL caused by index fragmentation during concurrent student enrollment batch writes, compounded by host swap thrashing.
Parameter Runbook Execution
The DBA team executed an online index rebuild (ALTER INDEX PS_JOB_RUN_CNTL REBUILD ONLINE), set Linux kernel swappiness to 10, and allocated 2,048 hugepages. CPU dropped from 100% to 22% instantly.
45-Minute Strategy Debrief
A single 45-minute debrief call was held with the IT Director to review permanent SQL baseline pinning and prevent recurrence for future enrollment cycles.
