Conflict with the CA Roscoe EXPORT Command

Any libraries that are allocated to CA Roscoe by the JCHKPLIB DD statement are not available to the EXPORT command. CA Roscoe uses an exclusive enqueue to gain control of the library to ensure that updates are single-threaded. Since these libraries are allocated DISP=SHR to CA Roscoe, the message DATASET UNAVAILABLE, TRY AGAIN LATER is generated.

The CA JCLCheck DEQUE option provides a solution to this problem by removing the data set from the queue. The easiest way to do this is to add a step to invoke CAZ2DEQ before the CA Roscoe online step. The necessary JCL is shown in the sample job in the OPTION Library. The DD statements between the JCHKFREE DD statements must be the same (ddname and dsname) as the PROCLIB DD statements you add to the CA Roscoe online step.
