IBM OS/390 User Manual

Before you start using your new OS/390 system, you must complete the
installation and tailoring process by customizing the system for your use.
Depending on what method you used to install the software, some of the items
listed below may already have been completed for you or you may have
contracted for some additional service assistance to perform these items. The
following items are not a complete list, but can be used as a general checklist:

Install remaining IBM Service

Exercise IVPs

Back up system, and test recovery by restoring it

Update VTAM and NCP definitions, generate the NCPs and test them

Update MVS SYS1.PARMLIB definitions and test them

Tailor SYS1.PROCLIB procedures and test them

Update JES2 parameters and test them

Update DFSMS parameters and test them

Update RACF security environment and test it

Update LE, language options and procedures and test them

Define TSO/E user IDs and test them

Define user catalogs and test them

Set up SMP/E maintenance environment and test it

Set up IPCS service aids and test them

Set up CICS and other application subsystems and test them

Set up application development environment and test it

Develop operations procedures for common and critical tasks

Test operations procedures and train operators

Set up installation standards, test and document them

Set up hardcopy and softcopy documentation libraries

Set up accounting and billing procedures

Once more, exercise IVPs, and back up system

If you need additional assistance to complete your production ready system, you
may want to contract for some services work to perform these items. The fees
for these items would be based on exactly what work was required. You should
ensure that all items performed as part of the services are documented so that
you can make any needed adjustments in the future.

Before you begin tailoring the new system, and at each stage of the tailoring
process, you should verify that the system is in good shape before you take the
next step. If your system was installed as part of a packaged offering, it was
probably verified before you received it.
