Performance improvements: - cleanup_database.ps1: Skip service deletion (saves ~25s per test) - Remove oradim -delete, sc.exe delete, registry cleanup - Add SPFILE deletion to ensure PFILE-based startup - Service now persists between tests for reuse - rman_restore_from_zero.ps1: Smart service check (saves ~15s per test) - Check if service exists before creating - Skip oradim -new if service already present - Only create service on first run or if missing Total time savings: ~40 seconds per weekly DR test Service lifecycle: Created once, reused indefinitely until manual cleanup Co-authored-by: factory-droid[bot] <138933559+factory-droid[bot]@users.noreply.github.com>
