DB2 Query Patroller is composed of components that run on the DB2 Query Patroller server, and components that run on the DB2 Query Patroller client. The client does not communicate directly with the server. DB2 Query Patroller uses DB2 tables to pass information between the client and the server. For this reason an administrator or operator needs to be able to distinguish between DB2 failures and DB2 Query Patroller failures.
Refer to the Troubleshooting Guide if a problem or system failure is suspected to have originated from DB2.
