This topic provides some debugging tips for resolving known scheduler problems.
Explanation | A SchedulerNotAvailable exception is created when running most Scheduler
API methods or WASScheduler MBean operations when the scheduler is configured
to use an Informix Version 7 database. The affected methods and operations
are: getTask, getTaskStatus, cancel, purge, suspend, and resume. The exception created is: com.ibm.websphere.scheduler.SchedulerNotAvailableException: java.sql.SQLException: Column (row_vers4ion) not found in any table in the query (or SLV is undefined). |
Possible causes | The SQL query that is used to load a task for Informix V7 databases has a typographical error: ROW_VERS4ION should be ROW_VERSION. |
Recommended response | Apply the next available service pack or use a more recent supported version of Informix. |
