10.1 Available User Exits

There are two types of user exits that can be used to modify
CA MICS logic: general exits, which apply to all the
installed products, and product exits, which apply only to
the product for which they are provided.

General exits allow user routines to be used for all products
that process the raw SMF data.  General exits are briefly
described in this guide. A more detailed description can be
found in Chapter 4 of the CA MICS System Modification Guide.

Product exits are classified according to their purpose and
include input, output, and parameter-related exits.

o  Input exits are invoked as the raw input records are read.
   Output exits are invoked just before CA MICS writes an
   observation to the CA MICS database.

o  The CA MICS Analyzer for CA-IDMS provides the general
   input exit, _USRSEL, which can be used to select or
   exclude data meeting special site-defined criteria, to add
   data elements, or to modify record fields as they are
   read.  In addition, the general input exit, _USRIHL, is
   provided at the end of input processing to permit
   examination of the CA MICS Input History Log SAS file so
   that the user can terminate the DAILY run if critical data
   is missing.

o  An output exit routine is provided for each file and can
   be used to selectively block the writing of specified
   records, alter data elements in the records, or produce
   additional records for the target file or a user-defined
   file.

o  Parameter-related exits are also user exits, but are
   defined as part of the standard CA MICS installation
   process.  They are normally associated with other
   parameters or options.  For example, the Account Code
   Derivation Routine is a user exit routine for completing
   values for account codes that were defined in
   sharedprefix.MICS.PARMS(IDMACRT), the Account Code
   Definition parameter member.  These exits are identified
   here but described in Chapter 7 of this guide.


The IDMS user exits are identified below:

    o  General Input Exits

       _USRSEL  - File Processing Selection
       _USRIHL  - Examine Input History Log

    o  Product Input Exits

       There are no unique IDMS input exit routines.

    o  Product Output Exits

       USRSSAC - IDMS Application Unit Counts File Exit
       USRSSAU - IDMS Application Unit Activity File Exit
       USRSSUA - IDMS User Activity File Exit
       USRSSIN - IDMS System Incident File Exit
       USRSSCL - IDMS System Calendar File Exit
       USRSSSY - IDMS System Activity File Exit
       USRTfff - DETAIL Tape Data Selection Exit

    o  Product Parameter-Related Exits

       IDMACRT - IDMS Account Code Derivation Exit
       IDMAURT - IDMS Application Unit Derivation Exit
       IDMRLRT - IDMS Transaction Type Exit
