Recommendations for allocating the job library data set (EELJBLIB)
The job library data set contains the JCL for the jobs that the agent for z/OS will submit. It is required by the agent. The data set is first allocated when you run the EELINST installation aid.
If you subsequently need to allocate more job library data sets, give your preference to PDSE data sets.
If you must allocate PDS data sets, allocate the job library data set with a only primary space allocation. If a secondary allocation is defined and the library goes into an extent when the agent is active, you must stop and restart the agent. Also, do not compress members in this PDS. For example, do not use the ISPF PACK ON command, because the agent does not use ISPF services to read it.
