How do I determine what user applications are running on the server and where to find the aggregation programs in the database? Please give me some suggestions.
The data dictionary is your best friend! You can look at anything and everything contained in the database using data dictionary views. For example, you can see what is running against your database at any given time by using the following query from the data dictionary views v$session and v$sqltext:
break on sid skip 1 on username column sid format 999 column username format a10 SELECT a.sid,a.serial#,a.username,b.sql_text FROM v$session a,v$sqltext b WHERE a.username is not null AND a.status = 'ACTIVE' AND a.sql_address = b.address ORDER BY 1,2,b.piece;
