The trace for some exceptions might has the following line: Caused by: com.ibm.db2.jcc.b.SqlException: DB2 SQL error: SQLCODE: -911, SQLSTATE: 40001, SQLERRMC: 2
Both the Observation manager and the Replication manager components access the same database tables, and this occasionally causes a deadlock problem. The deadlock exception is thrown in the WebSphere® Application Server SystemOut.log file. If the exception has in its trace
Caused by: com.ibm.db2.jcc.b.SqlException: DB2 SQL error: SQLCODE: -911, SQLSTATE: 40001, SQLERRMC: 2
Then the SQL code -911 indicates that this is a deadlock problem.
The exception is totally recoverable when either of the components, Observation manager or the Replication manager, finishes its transaction.
