DB - How to monitor Oracle datapump jobs

These days there is lot of work around database migrations not only but mainly to cloud providers. One of the ways to migrate Oracle databases is using data pump (expdp/impdp). In general works fine, it allows an easy way to bring the database even different OS. It is always good to monitor the progress, to know where we are and estimate how long we are from the end. In this post, I am sharing some queries to help with database monitoring progress. The queries can be easily tailed to various scenarios. Starting with a simple one - the track the number of objects loaded during an import operation. When there is a massive amount of errors during the import. Drop and run the import again. The bellow query can be useful also to monitor the number of objects if we are dropping the users. Here, I’m making the assumption there were no other database activity in progress on the last 24 hours. select owner, count(0) from dba_objects where owner in ( select username from dba_users where created...

DB – How to monitor Oracle database long ops ?

As DBAs, some questions we are often asked and to be fair we ask ourselfs when we are doing massive operations, are : Is the database doing something? How long the database takes to complete the task? There a data dictionary view, GV$SESSION_LONGOPS whom is really usefull for monitoring and to provide estimated time to get the task done. Starting with a first example, a query for general propose . set lines 240 col message form a100 col opname form a50 select * from ( select round(l.sofar/l.totalwork*100,2) as complete, --l.* l.sid, --l.opname, l.message, l.start_time, l.time_remaining/60 "minuts remaining", l.elapsed_seconds from gv$session_longops l where totalwork !=0 ) where complete < 100; The view is also usefull on specific operations such as Oracle Recovery Manager (RMAN) jobs monitoring, this query returns information about backup,restore and recovery. select sid, serial#,opname, context, sofar, totalwork, round(sofar/totalwork*100,2) "%_complet...
