Change Non-Maskable Resources to Support Masking

For predefined resource classes with RESCODEs 040 to 0FF, a class that was originally defined as NOMASK can be changed to MASK. Masking provides the ability to group sets of resources whose names share similar characteristics.

Note: A class that is defined as MASK cannot be changed to NOMASK.

Follow these steps:

1. Identify ownership for the resource class:
   1. Issue the following command to see all ownerships:

      TSS WHOOWNS resclass(*)
      

      resclass

      Specifies the name of the resource class.

      The product displays output that shows ownership information about these resources.

   2. Issue the following command for each 'xxxx' that shows up in the WHOOWNS output:

      TSS WHOHAS resclass(xxxx)
      

      The product displays output information regarding who has access to these resources.

2. Review the output, then issue TSS REVOKE command information to revoke all permits for the resource class.
3. Issue TSS REMOVE command information to remove all ownerships in the resource class.

   The product removes ownerships as instructed.

4. Change the resource class from NOMASK to MASK.

   The resource class now supports masking.

5. Issue TSS ADDTO command information to reassign all ownerships that you removed.

   The product reassigns ownerships as instructed.

6. Issue TSS PERMIT command information to redo all the permits that you revoked.

   The product restores permits as instructed.
