I have activated Oracle trail using the following steps :
1) Connect as Sys
2) Execute Catalog.sql Procedure
3) Execute CATAUDIT.SQL Procedure
4) Issue the command : Audit All; in order to Audit all DB activities
I have Executed many SQL statements but can't find any records in SYS.AUD$ view !!!
Are there any missing actions should be taken in order to make audit trail work
Thanks in advance
