We have an application on IBM WebSphere Application Server 7.x and it connects to a remote database on z/os DB2 10.x. For annual operation, DB2 shut down and restarted. After starting the database, we first get
and then we get
The database manager is not able to accept new requests, has terminated all requests in progress, or has terminated this particular request due to unexpected error conditions detected at the target system. ERRORCODE=-4499, SQLSTATE=58009
The connection between WebSphere and DB2 tested by 'test Connection' in WAS datasource. Both systems are up and running but there is no correct connection between them! There was no change in DB2, WAS, and JDBC driver.
Update: The JDBC driver version is 4.15.134, connection properties is IBM WebSphere default setting and the connection is direct to DB2. Another problem later showed that while the connection still has the problem, executing the query directly on z/OS's DB2 gets the same the error. The query consist of a select with a join on two different tables, selecting on each table is ok, but the final query does not work and gets ERRORCODE=-4499, SQLSTATE=58009.
Update 2 The detail of environment is: IBM WebSphere Application Server 188.8.131.52, DB2 10.1, Java version 1.6 SR16 and z/OS 1.13.
This specific query gets the error in all environments, on all application server, z/os SPUFI, database viewer, such as DBeaver.
Any help is greatly appreciated.
