RE: need to move from monthly full save, fix apply, IPL to semi-annually

Gerald--

We use IBM i methods-- we have the luxury of running a full Option/21 every night. A far cry from when we could only do that once every 3 years before an OS upgrade!!

We actually run a program that includes all of the commands that make up the Option/21; lets us run under program control instead of having an operator standing by.

Paul,
do you back up the clone via IBMi or BRMS methods?

Our storage is on a V9000, and we can clone (flash copy) our production
partition. We do that daily and run our backups from the clone.

We IPL to:

-- Apply PTFs every 2-3 months, often enough to stay current, but not risk
being 'early adapters.' Our daily backups handle saving the OS.

-- Reorganize files that have too many deleted records. Yes, most files
re-use deleted records, but there are some... the program logic, for
whatever reason, involves mass deletes of records that never seem to get
re-used.

-- Programmer requests that require a 'quiet time.'

So far (knock on wood) we've been able to schedule monthly IPLs, but, like
you, we've skipped some when necessary.
We usually schedule a 7-hour window, but have been returning the system
after 4-5.

Our business is now at the point where Sunday morning uptime is critical.
we have been performing a full save (restricted state, savsys, savlib
*NONSYS, dlo, sav), followed by a IPL that will activate any fixes that
have been applied...

we have been "aggressive" with applying fixes, but are comfortable leaving
the system running for many months where it makes sense...

how do others perform patching and saving the OS on a twice a year basis?
