Troubleshooting
Problem
This scenario is based on the usage of the Windows S-TAP monitoring DB2 Database.
The concern arises after Guardium® Administrator receives Windows S-TAP inactive alert frequently and needs to go and manually restart the Windows S-TAP to resume the DAM activities.
Symptom
- Windows S-TAP stops suddenly and post restart works fine until the next stoppage
- Post executing the Windows S-TAP diagnostics, it was evident from the diag_out.txt file that the Windows S-TAP was not keeping up with the DB2 database traffic
