> MappingTool fails requires appropriate DESCSTAT parm value on DB2 for z/OS
> --------------------------------------------------------------------------
>
> Key: OPENJPA-702
> URL: https://issues.apache.org/jira/browse/OPENJPA-702
> Project: OpenJPA
> Issue Type: Bug
> Components: docs
> Affects Versions: 1.3.0
> Environment: OpenJPA trunk, DB2 for z/OS V8, IBM JCC type 4 JDBC
> driver.
> Reporter: Jeremy Bauer
> Priority: Minor
> Attachments: OPENJPA-702.patch

> When running with the IBM JCC driver to a DB2 on z/OS system the mapping tool
> may fail with the stack trace below if the DB2 DESCSTAT subsystem parameter
> is not set to 'YES'. This parameter controls whether column names are
> returned in a JDBC metadata query. Specifically, the mapping tool uses the
> JDBC-spec defined column names to query column metadata and that query will
> fail if DESCSTAT is set to 'NO'. By default DB2 on z/OS version 8 and later
> set the DESCSTAT parameter to 'YES'. However, if it gets set to 'NO' ,
> explicitly or possibly via a DB migration, the mapping tool will fail.
> org.apache.openjpa.persistence.PersistenceException: [ibm]
> [db2][jcc][10150][10300] Invalid parameter: Unknown column name TABLE_SCHEM.
