Hi Gurus,

I need your help,

Actually i am facing a problem on production server in which OS is Windows Server 2008 , Oracle 11.0.1.0

Data is approx 9GB.

What i do is previously i Schedule a backup job in OEM for 2 times full backup, in that schedule job is running on time and after completeion it executed sucessfully. but due to seme change in Backup policy i change the scheduling and remove the old one but now whenever i try to schedule autobackup the job starts on time but after no of hrs the schedule execution still show job is running , as my data backup is coming properly to the specified location which is not flash_recover_manager. One thing more my SYSTEM tablespace is approx 92.8 % full and may be this is the problem or controlf file sizeing may be the problem but i am not sure. Can u please tell me can i add datafile to system tablespace to increase its size while db is up or change control file size & how. One thing more , when i try the same scheduling steps on my local machine or any other machine scheduling is done fine and it shows suceeded after completion.


At present i am not able to post snapshot of alertfile or pfile.


Can somebody facing the similar scenerio help me out.


please help me as i am in need so much


Thanks in advance

You need to determine whether RMAN is actually doing anything. Run a query such as this
select opname,target,sofar,totalwork,elapsed_seconds,time_remaining
from v$session_longops
where sid in (select sid from v$session where program like '%rman%')
and time_remaining > 0
/

a few times while RMAN is running, on both databases.
You also need to determine if RMAN is hanging, and if so why:
select event, seconds_in_wait from v$session where program like '%rman%' and wait_time=0;

But don't just run the queries and hope, read up on the definition of the views first so that you can explain what you see.
