Oracle Delete archive log script

 

Archive logs record database operation records, which are the basis for data recovery. If the archive mode is enabled for the database, a large number of archive logs will be generated. Of course, if there is an RMAN backup, logs that have been backed up can be deleted after the backup. If RMAN backup is not used, you need to delete the archived logs by yourself. The following scripts reduce DBA workload.

Done

Or use the script:
Del_arc.sh
Find/u01/backups-mtime + 10-name "*. DBF"-exec Rm-RF {}/;

 

Windows:

 

Del_arc_orcl.bat
Forfiles/P d:/arc_orcl/M *. DBF/D-3/C "CMD/C del @ file"

 

Add del_arc_orcl.bat to the scheduled task.
