Calculate Required Blocks

This procedure determines the number of blocks needed to create the security file.

Follow these steps:

  1. Edit TSSMAIND and SECPARMS to conform to your site's standards.
    MLSBLOCKS=?????

    (Optional) Each MLS index entry requires one entry with a length of 14 plus the length of the resource name. For information, see the Multilevel Security Planning Guide.

  2. Specify the name of the dummy run in the SECDUMMY member referenced in TSSMAIND.
  3. Set the ID=DUMMY parameter to consist of a maximum of eight characters.
  4. Execute a dummy run with the JCL in TSSMAIND.

    The number of blocks required is returned.

Note: Running TSSMAIND causes an SD37 ABEND or U1520. This is normal.
