Compression services is available (CVTCMPSC on). The compression services structure is initialized without error.
Compression services completed only partial initialization. Only existing compressed format data sets will be processed. No new compressed format data sets will be allocated.
The most common cause of this condition is when not all DBBs are successfully loaded due to an error.
Compression services is not available. The compression services global control-block structure could not be built, or an unexpected abend occurred during validation of the structure.
The most common cause of this condition is when CMP cannot access the SYS1.DBBLIB data set. The user should make sure SYS1.DBBLIB exists and is cataloged. SYS1.DBBLIB is built during DFSMS installation.
There might be a LOGREC entry for the CMP003E message with the return and reason codes for the error.
