SAP-reducing sap disk space

Recently, Dev servers have insufficient space and cannot be started. The actual data volume is not large and you don't want to increase the hard disk space any more. You can try to delete useless data to make it run.

1. Delete files in the/Oracle/dev/sapbackup directory.

2. Delete the archive log files under the/Oracle/dev/oraarch directory and retain only several log files of the specified period.

It adds a little space for Dev to run.
