Hi,
If you have big database about more than 1 TB, then your backup and export operations are taking long times.
If you start long operations such as RMAN Backup and Datapump Export in Oracle database, probably you want to see progress of these operations.
You can see and monitor RMAN Backup progress with following script.
SELECT SID, SERIAL#, CONTEXT, SOFAR, TOTALWORK, ROUND(SOFAR/TOTALWORK*100,2) "%_COMPLETE" FROM V$SESSION_LONGOPS WHERE OPNAME LIKE 'RMAN%' AND OPNAME NOT LIKE '%aggregate%' AND TOTALWORK != 0 AND SOFAR <> TOTALWORK order by 6 desc;
You can monitor Datapump Export ,Import and other long operations with following script.
SELECT SID, SERIAL#, CONTEXT, SOFAR, TOTALWORK, ROUND(SOFAR/TOTALWORK*100,2) "%_COMPLETE" FROM V$SESSION_LONGOPS WHERE OPNAME NOT LIKE '%aggregate%' AND TOTALWORK != 0 AND SOFAR <> TOTALWORK order by 6 desc;
