Management Class Synchronization Service

The Management Class Synchronization Service identifies data sets whose existing management class is different from the management class that would be assigned by the current ACS routines or SMSACSxx rule lists.

See the following sections in this topic for more information:

What you can do with the service

The Management Class Synchronization Service synchronizes data sets to new or changed management class assignment rules.

To change the management class of a data set, generate control cards for the IDCAMS ALTER command.

Organization of the report

The Management Class Synchronization Service does not produce a report.

The control card generation facility is used with the service to build control cards to change the management class of the selected data sets.

Usage notes for creating the service

Consider the following information when using the Management Class Synchronization Service:

  • The BMC AMI Storage subsystem must be executing to run the Management Class Synchronization Service.

  • All selected data sets are processed by the SMS management class ACS exit and the SMSACSMC function. If the returned management class differs from the management class that the data set already has, control cards are generated; if the returned management class is the same as the data set’s current management class, control cards are not produced.

    Warning

    Important

    Even though the data set has been reprocessed by the ACS exit and SMSACSMC function, its management class is not changed by the synchronization service. To make a change, set up the generated control cards to alter the management class.

  • Regardless of whether the SMSACSMC function is running in active, simulated, or inactive mode, the function still processes the data sets that are specified in the reporting INC statements. However, if the function is deactivated in the SMFUNCxx member by ACTIVE=NO, the function does not process any data sets. The SMSMANAGED parameter of the SMSACSTE function has no effect on the report.

    Error
    Warning

    Many BMC AMI Storage selection parameters are not available to the SMSACSxx functions filter and rule lists during the synchronization service. For example, job execution-time parameters, such as job name and ddname, are valid for the report job only and thus are not really applicable to any SMSACSxx filters or rules that may reference such parameters. The selection parameters that are available to the SMSACSxx filter and rule lists are:

    • CAT (catalog name)
    • DSN (data set name)
    • DSNn (data set name qualifiers 1 through 8)
    • HLQ (data set name high-level qualifier)
    • LLQ (data set name low-level qualifier)
    • NQUAL (number of qualifiers in data set name)
    • DSORG (data set organization)
    • SIZE (data set size)
  • Filter and rule list entries which select on other parameters (for example, SYSID or DSTYPE) will not be considered for matching. See Filter-and-rule-lists.

  • The following example shows two data sets that have management classes assigned and the SMSACSMC rule list that changes the management classes:


    Data set name

    Management class

    GLYTD.DIV90.TRANS.ACT

    HOLD15

    GLYTD.DIV90.TRANS.MSTR

    HOLD30

    The SMSACSMC rule list has been changed to assign new management classes to both these data sets.

    The following MCS specification will generate the cards that follow:

    EXCLUDE MIGRATED DS = YES
    REPORT TYPE=MCS
    INCLUDE DSN=GLYTD.DIV90./
    GENERATE CARDS DD=CARDOUT
    ALTER &DSN -
      MANAGEMENTCLASS(&MCNAME)

    cards:

    ALTER GLYTD.DIV90.TRANS.ACT -
         MANAGEMENTCLASS(HOLD90)
    ALTER GLYTD.DIV90.TRANS.MSTR -
         MANAGEMENTCLASS(HOLD180)
