Using the parmlib member EDGRMMxx

This topic describes the options that you can specify in the parmlib member EDGRMMxx. You can use system symbols to enable easier sharing of the EDGRMMxx parmlib member. See z/OS MVS Initialization and Tuning Reference for how to use system symbols in parmlib members.

Do not specify duplicate operands. If you do, DFSMSrmm uses the last value you specified.

Note: DFSMSrmm does not ignore columns 72 to 80 in the parmlib member. However, if you wish to take advantage of the symbolic parmlib parser, you should avoid placing any data, even comments, in columns 72 to 80.

Specify the options using this format:

      command operand1(value1) operand2(value2) -
              operand3(value3)

      command operand1(value1,value2, +
                       value3,value4) +

You can include comments in the parmlib member by enclosing your comments within ⁄* *⁄ as shown in this example. Comments can precede and follow the parameters as well as appear within the parameters:

      /*Your command syntax example*/
      command operand1(value1) operand2(value2) /* comment */ -
              operand3(value3) /*end of command*/

DFSMSrmm processes the commands in the EDGRMMxx parmlib member and then, if there is a second member named, processes the second member. Any OPTION operands specified, other than MEMBER, override the values set in the first member. The MEMBER operand is ignored if it is also specified in the second parmlib member. Any other parmlib commands can add to, but not replace, update or duplicate, any command from the first parmlib member. The processing by DFSMSrmm is as if all of the parmlib contents of both members had been specified in a single parmlib member.

The parmlib member EDGRMMxx uses these commands:

LOCDEF that is described in Defining storage locations: LOCDEF.
MEDINF that is described in Defining media information: MEDINF.
MNTMSG that is described in Defining mount and fetch messages: MNTMSG.
OPENRULE that is described in Controlling the use of tape volumes: OPENRULE.
OPTION that is described in Defining system options: OPTION.
PRTITION that is described in Partitioning tape volumes: PRTITION.
REJECT that is described in Defining tapes not available on systems: REJECT.
SECCLS that is described in Defining security classes: SECCLS.
VLPOOL that is described in Defining pools: VLPOOL.

Use the OPTION command to set defaults for DFSMSrmm on a system. Use the VLPOOL command to override the system-wide defaults for particular tape pools. Commands in the parmlib member EDGRMMxx are processed for symbols substitution before the commands are parsed.
