Issue/Introduction

Primary/Shadow configuration requires that each MUF region runs with its own PXX dataset, i.e. PXX cannot be shared between the two MUF regions.

How to use a single JCL deck to start both the members of a Primary/Shadow MUF pair.

Environment

Resolution

Here are two possible options:
1) use a temporary PXX dataset in the JCL:
   //PXX DD DSN=&&PXX,UNIT=SYSDA, 
   //    SPACE=(TRK,(1000)),DISP=(,DELETE)

2) if the MUF STCs are running on the two different LPARs (e.g. TST1 and TST2), then two permanent datasets can be allocated with dsn names like:
   hlq.TST1.PXX
   hlq.TST2.PXX
   and then the PXX in the MUF startup can be referenced using the &SYSNAME variable:
   //PXX DD DSN=hlq.&SYSNAME.PXX
