It is highly recommended to use parameters BLOCKS and PREFIX in conjunction with parameter ALLOCOPT=JOBSDSNx. If parameter BLOCKS is not specified, the default Control-D installation parameter AMBLK#D is used. This parameter value may be too small, resulting in one JOBSDSN dataset containing a small number of jobs.
If parameter PREFIX is not specified, the default prefix is taken from the Control-D installation parameter AMPREFD (unless ALLOCOPT=JOBSDSN1, in which case the default prefix is taken from the installation parameter JB1PREF). Using this default prefix may cause regular CDAM datasets and multi-job CDAM datasets to become intermixed.
Note: The prefix used for multi-job CDAM datasets must differ from the prefix used for other CDAM datasets.
The PREFIX is the unit of integrity of multi-job CDAM datasets. If two (or more) report decollating missions with ALLOCOPT=JOBSDSNx refer to the same CDAM prefix, the sysouts are written to the same multi-job CDAM dataset. Different decollating missions with ALLOCOPT=JOBSDSNx can refer to different prefixes. In this case, each one is directed to a different multi-job CDAM dataset.
Note: The Using the same prefix for regular CDAM datasets and multi-job CDAM datasets may affect the reliability of utility CTDAMUTI. For more information, see Using Utility CTDAMUTI on Multi-job Datasets.
