Space for archived sysouts

Ensure that enough space is available to archive SYSDATA for all jobs that execute under Control-M and for which a Y value for AUTO-ARCHIVE is specified either explicitly or by default. Control-M allocates space as needed on the devices defined by the AMVOL and AMUNIT parameters in the CTRPARM member in the IOA PARM library, until all available space on the volumes is allocated.

• If SYSDB=Y is specified (recommended)

  The SYSDATA of all jobs is written to a common data set until it is filled; then a new data set is automatically allocated. This minimizes the space required in the catalog and in the VTOC on the defined disk.

• If SYSDB=N is specified

  Since every job execution results in one cataloged data set, make sure that the VTOC of the defined disks is large enough to contain all the data sets, and that enough space is available in the catalog. It is recommended that a user catalog be defined for the prefix defined in the AMPREFR parameter in the CTRPARM member in the IOA PARM library.

Note: Do not release unused space from SYSDATA files by automated data management products (such as FDR and DMS/OS).
