During initialization, the DB2 for z/OS ECCR tried to get schema version information for a table. The ECCR gets this information by dynamically allocating and reading the tablespace data set or partition data set that contains the table. After processing the schema version information, the DB2 ECCR dynamically unallocates, or deallocates, the data set. However, the dynamic unallocation request failed. This error can occur only if you are using DB2 Version 9.1 or later.
This message includes the name of the data set that was being unallocated and the return code, error reason code, and information code returned from the dynamic unallocation request.
Processing continues. However, the failure to unallocate the data set might lead to resource problems in the ECCR later. For example, the TIOT entry that was used when the data set was allocated might not be freed, which could lead to the ECCR exhausting the available space in the TIOT.
To determine the reason for the unallocation failure, examine the return and reason codes that are reported in this message in conjunction with operating system documentation. You might need to recycle the ECCR to prevent future related problems. If you cannot determine the reason for the dynamic unallocation failure, contact Informatica Global Customer Support.
