208 Converting to DFSMSrmm from TLMS
6.2 Reviewing the current environment
See Figure 2-1 on page 51 to review the flow of events that we followed in
converting from TLMS to DFSMSrmm. You must collect and then analyze all
information about the current tape management environment.
Once you have reviewed the environment and understand the main differences
between TLMS and DFSMSrmm, you will better understand what you must
change during the conversion process.
6.2.1 Collecting information
The information that you collect about the current environment should include:
TLMS reports used daily or occasionally
Every day there should be a TLMS report that the operator uses to move the
cartridges between the desired locations and to return tapes to the scratch
pools. You can use the DFSMSrmm supplied reports, but if you want to avoid
changes to the layout of this report, using REXX or DFSORT you can tailor
the DFSMSrmm reports to make them similar to the TLMS reports.
DFSMSrmm Primer, SG24-5983, provides some useful examples how to
create the reports.
Exits installed
Collect information about TLMS exits installed in your environment so you
can ensure that you can achieve the same function in the DFSMSrmm
environment. For example, you must check the OAM exits, CBRUXENT and
CBRUXEJC, if you have an SMS managed IBM ATL installed.
PARMLIB options used
You must review TLMS PARMLIB options before you start DFSMSrmm
because you may have to modify the DFSMSrmm options according to the
TLMS environment.
