Enterprise Manager

Oracle Installed: 12.1.0.2.0

OEM Installed: 12.1

Linux Installed: Red Hat Enterprise Linux Server release 6.7

Problem: My OEM Linux Server's disk space keeps filling up to almost 100%. I have tried deleting the logs via ADRCI but it does not creates enough free disk space. I use this OEM to keep an eye on my ORACLE RAC servers

  1- Can I delete anything from the mgmt.dbf or any other dbf file ? I will post the screen shots below that will show the size of dbf files.

  2- OEM Cloud Control Guide recommends running the following command to reduce the retention period of severity data and EVENTS purge policy, I don't know where to run that command?

      I tried running it in SQL PLUS but I get an error, I tried running it on OS command line but got an error

     em\_purge.modify\_purge\_policy\_group('EVENTS', NULL, \*1\_new\_purge\_hours\*);
