Implement COMMUNICATION=NONE

To implement COMMUNICATION=NONE, you customize certain parameters in the MIMINIT member.

To select the NONE communication method

In the MIMINIT member:

1. Define a single system on the DEFSYS statement

   DEFSYS(SYSA,01,SYSA)
   

2. Define the NONE communication method:

   MIMINIT COMMUNICATION=NONE
   

3. If you will be testing ECMF, define a checkpoint file for this system to use:

   MIMINIT CHKPTDSN=sysa.dsn
   

   Alternatively, you can use the ALLOCATE command in the MIMINIT member to define the checkpoint files:

   ALLOCATE DDNAME=MIMCKP00,DSNAME=sysa.primckpt
   ALLOCATE DDNAME=MIMCKP01,DSNAME=sysa.altckpt
