Hi Chris,
Be sure that you do not want more than one audit file per day. Thus, you should set only:
rsau/max_diskspace/local
-> here FN_AUDIT should use only +++ in the pattern, e.g. audit_++++++++.
If you really want more than only SAL file per day, then set:
rsau/max_diskspace/per_file
rsau/max_diskspace/per_day
-> here FN_AUDIT should contemplate this, e.g. audit_++++++++_######.
It is worth to read the following two SAP notes:
909738 - SecAudit: Files are created with other names
539404 - FAQ: Answers to questions about the Security Audit Log
I hope this helps,
Cris
