Define a User Catalog, Specifying SMS Keywords: Example 1

In this example, an SMS-managed user catalog is defined.

//DEFUCAT  JOB  ...
//STEP1    EXEC PGM=IDCAMS
//SYSPRINT DD   SYSOUT=A
//SYSIN    DD  *
    DEFINE USERCATALOG -
           (NAME(USERCAT1) -
           ICFCATALOG -
           STRNO(3) -
           DATACLAS(VSDEF) -
           STORCLAS(SMSSTOR) -
           MGMTCLAS(VSAM))
/*

The DEFINE USERCATALOG command defines an SMS-managed user catalog, USERCAT1. Its parameters are:

• NAME specifies the user catalog, USERCAT1.
• ICFCATALOG specifies that the user catalog is to be in the catalog format.
• STRNO specifies that up to 3 concurrent requests to this catalog are to be processed. Like BUFSP, STRNO is not one of the data class attributes. If STRNO or BUFSP is not specified, the system will take the default established by access method services.
• DATACLAS specifies an installation-defined name of an SMS data class, VSDEF. The data set will assume the space parameters, and the FREESPACE, SHAREOPTIONS, and RECORDSIZE parameters contained in this data class. If your storage administrator has established ACS routines that will select a default data class, this parameter is optional. If a default data class is not assigned to this data set, however, you must explicitly specify any required parameters, in this case the space parameter, or the job will be unsuccessful.
• STORCLAS specifies an installation-defined name of an SMS storage class, SMSSTOR. This parameter is optional. If it is not specified, the data set will assume the storage class default assigned by the ACS routines.
• MGMTCLAS specifies an installation-defined name of an SMS management class, VSAM. This parameter is optional. If it is not specified, the data set might assume the management class default assigned by the ACS routines.
