File Maintenance (OS Files, Purging)


Should you find that Oracle database's ability to self maintain peripheral logs and files is inadequate this might help. If nothing else you can use this as a fail-safe so your OS volumes do not become full.

Manual script below. For an ADR script example ( go here.

One directory that can be overlooked is where old patches are stored.

  1. Get existing dirs:
    ls -l $ORACLE_HOME/.patch_storage > /tmp/dir0.txt
  2. Get lsinventory found dirs:
    $ORACLE_HOME/OPatch/opatch lsinventory | grep -E "(^Patch.*applied)|(^Sub-patch)"
  3. Remove directories of patches not found in the lsinventory.
    • Directory names would be prefaced with the patchid for example: 13343438_<timestamp>.
    • Do not remove the Sub-patch folders.

Cron Example (via root)


 # Daily
 00 05 * * * find $AUD_DIR_GRID  -type f -name '*.aud' -mtime +15 -delete > $OUT/AUD_DIR_GRID.out
 15 05 * * * find $AUD_DIR_RDBMS -type f -name '*.aud' -mtime +15 -delete > $OUT/AUD_DIR_RDBMS.out

Adjust as needed for your environment.
