7.3.7 IMS Suspend File DD Statements (IMSSPND)

The IMS suspend files (SUSPENDO and SUSPENDI) are used to
hold IMS data for which a complete transaction cannot be
constructed.  Each file holds five tracks of data.  The
prefix.MICS.PARMS(IMSSPND) member is used to define the DD
statements for these files.  You must review these
definitions to determine whether the default definitions are
suitable for your installation.  Consider the following:

1. Suspend files are NOT used when processing BMC MAINVIEW
   for IMS Online data or IMS LOG data that has gone through
   the CA MICS IMS Log Data Extractor Option.

2. You must edit the JCL for the SUSPENDI and SUSPENDO DD
   statements in prefix.MICS.PARMS(IMSSPND), specifying the
   UNIT= and VOL=SER= keywords to ensure that your IMS
   Analyzer suspend files are allocated to permanently
   allocated data sets.

   Remember that, by specifying VOL=SER, you must catalog the
   data sets because MVS will not do so automatically.

NOTE:  This member contains CA MICS Generator Control
       Language statements in addition to the DD statements.
       These other statements should not be modified if you
       alter the DD statements.

A worksheet has been provided in Figure 7-8.
