To control the operation of multiple instances of the
Collector, running
on different CICS regions,
from a single CICS terminal,
you must share the dependency
and affinity data
files and the control record file across all the regions being monitored.
To share the files use either:
- VSAM record-level sharing (RLS). For information about using VSAM
RLS in CICS, see the CICS Installation Guide.
- Function shipping to a file-owning region (FOR). For information
about CICS function shipping,
see the CICS Intercommunication
Guide. If you use function shipping, it is recommended that, for
performance reasons, you define the files as local to the region in
which you expect to do most monitoring activity and remote in all
the other regions to be monitored.
To migrate the VSAM control record file that you used in CICS IA Version 1.3, Version 2.1,
Version 2.2 or Version 3.1 to CICS IA
Version 3.2, use one of the following methods:
- Run the job that is described in Migrating the VSAM control record file. You must first follow the steps in this section
to create empty dependency and affinity data files and a control record
file in CICS IA Version 3.2
format.
- Run the CIUJCLCC job in
hlq.SCIUSMP1.OUT
.
For VSAM file space allocation refer to
VSAM data set allocation.
To create the dependency and affinity data files, and the control
record file, review and run the following jobs:

- hlq.SCIUSMP1.OUT(CIUJCLCA)
- hlq.SCIUSMP1.OUT(CIUJCLCC)
