You can use the DFSMSrmm-supplied samples without modification or use them as examples to produce specific customized reports from DFSMSrmm information. You can change the DFSORT or ICETOOL control statements and job steps to create reports for your installation. Consider these things that you can do to the samples for use in your installation.

JOB card

You might submit jobs from Time Sharing Option (TSO) and have your system automatically generate a job card for you. If a job card is not automatically generated, provide a job card by replacing the commented job card with one that is acceptable on your system.

Work Space

DFSORT and ICETOOL can generally automatically allocate any resources they need, such as work space, storage, Hiperspace™, dataspace, and so on. The resources allocated are based on system information, data set information, and the DFSORT installation defaults that are specified by your site. However, if necessary, you can change the resources used by DFSORT and ICETOOL in a variety of ways including:

• Specifying run-time options for the type and maximum number of dynamically allocated work data sets, the maximum amount of storage, Hiperspace or dataspace, and so on. For example, you can specify:

  //DFSPARM DD *
   OPTION DYNALLOC=(3390,8)
  /*

  to tell DFSORT or ICETOOL to allocate a maximum of eight work data sets on 3390 devices (instead of the IBM-supplied default of three work data sets on SYSDA devices).
• Specifying JCL work data sets. For example, you can specify:

  //SORTWK01 DD UNIT=SYSDA,SPACE=(CYL,(50,50))
  //SORTWK02 DD UNIT=SYSDA,SPACE=(CYL,(50,50))

  to tell DFSORT or ICETOOL to use the two JCL work data sets specified, instead of dynamically allocating the work data sets.

DSN keyword

You do not need to change the DSN keyword where temporary data set names are specified. When a specific data set name is used, you should change the name to one that can be used in your installation.

SPACE keyword

You can change the SPACE keyword values. Examine your installation's tape activities and perform trial runs to arrive at suitable values for primary and secondary space.

UNIT keyword

You can change the UNIT name used as required. Specify a value that will allocate to a DASD device type.
