Oracle 9i version : alter system archive log current hangs indefinitely

in Database Backup and Recovery (MOSC) 13 comments

Hi Team,

In oracle 9i , inside a RMAN backup job we have given alter system archive log current statement.

But it hangs indefinitely and the redo log switch between sequences takes more than 230 hours for one log switch and sometimes it gets completely sooner.

Below are the run times for a redo log file switch frequency:


   RECID START_TIME             RECID END_TIME             MINUTES

---------- ------------------ ---------- ------------------ ----------

 17058  31-jan-21 09:43:26      17059 10-feb-21 03:29:50  13860.83

 17101  02-mar-21 10:50:42      17102 11-mar-21 11:21:48   12782.4


Below are the run times when it runs normally and the backup get completed sooner:

   RECID START_TIME             RECID END_TIME             MINUTES

---------- ------------------ ---------- ------------------ ----------

 17102 11-mar-21 11:21:48     17103 11-mar-21 12:07:48     47.92

Howdy, Stranger!
