Re: Pitfalls of duplicated IBM commands when OS is upgraded?

Not only adding parameters, but they have (in a limited way) changed
several defaults as well.

My standard answer to that question is you need a CLP program that
completes ALL THE CHANGES you have made so you can run it after the upgrade.

For instance, have any print files been modified directly instead of making
copies, subsystem description changes, IBM supplied job description
changes? The list goes on, but you get the point. One CLP that sets all
of that and your upgrade will go somewhat more smoothly.

It is NOT out of the realm of possibility for IBM to add a new parameter to
a command which the CPP is expecting.

It's been ages since I last worked in a shop when an OS was upgraded. I
think I know the answer to this, but would appreciate confirmation.

I've duplicated several IBM commands to shorter named commands in our
shop's tools library. (I know the PDM commands in QSYS are proxies to

the

same named commands in QPDA, so I duplicated those from QPDA.) Will
upgrading from 7.4 to 7.5 "break" the commands I duplicated from IBM
commands? I don't expect any of these commands (DSPMSG, WRKaaaPDM,
WRKSPLF, etc.) will have any of their function changed.
