[ORACLE] BACKUP

If the PDB$SEED is not updated then the  INCR BACKUP LVL 0 rman does not backup it.

 

To prevent this and to get each time you perform the INCR BACKUP LVL 0 the content of the datafiles of the PDB$SEED, here is the command to run : 

[ORACLE] Check DB Activity HTML version

check_db_activity_html.sh performs a quick health and activity snapshot across multiple Oracle database instances on a host. It automatically discovers instances from PMON processes or accepts an explicit list of SIDs, initializes the environment per SID, connects as SYSDBA, and captures key runtime indicators (state, sessions, waits, Data Guard lag, long operations).
Output is written to a HTML file.
