Re: The problem with SAVCHGOBJ . . .

[Luis Rodriguez <luisro58@xxxxxxxxx>]

Rob,

We used to do a SAVLIB/SAV once a week here, with a SAVCHGOBJ everyday.
Also, a library with our Backup & Recovery CLs and procedures, SAVSECDTA,
SAVCFG and a file with a list of libraries was saved daily.

Besides the small detail of what would happen when you create a lib on a
Monday and lose it on Friday (just before Saturday's SAVLIB), if your
SAVCHGOBJ uses REFDATE(*SAVLIB), you only have to restore the latest
SAVCHGOBJ tape (not need to "Restore from every daily SAVCHGOBJ").

Our recovery sequence (never needed it, fortunately), was something like
RSTOBJ from the last SAVCHGOBJ and then a  RSTOBJ from the last SAVLIB with
OPTION(*NEW), MBROPT(*NEW) (A previous process would have made sure of
creating any missing library)
