Environment
CA/1 - R14.0
Cause
For some combinations of block size and record numbers, the access of the new TMC may fail. This occurs when the TMC is blocked and includes a short block at the end, and when the number of DSNBs is so small that the Volume Definition Record resides in this last short block.
Resolution
Avoid the error condition by adding a sufficient number of DSNBs, or by allocating the new TMC with a different BLKSIZE.
When a TMC BLKSIZE of 8840 is chosen, there will be 26 340-byte physical records per block (26 * 340 = 8840). In this case the minimum number of DSNBs for this TMC would be 52 (2 DSNBs per physical record, 26 physical records per 8840 block)..
Additional Information
For further details please refer Allocate the TMC and AUDIT datasets.
To avoid these abends use the recommended block size of 8840 for the TMC and 8880 for the AUDIT datasets.
