Nothing I have ever heard. Where is that documented? If undocumented, then rather than /IBM recommends/, perhaps instead /someone within IBM had once alluded, suggested, or .../ is a more appropriate implication.?

Applying a large amount of PTFs immediately has caused issues in the
past.

That would seem likely either to be a defect issue for which IBM should have provided corrective(s), or arisen from a usage issue that could be resolved by modifying the processes to match the requirements; e.g. special instructions of the PTFs.

Given the special instructions for the set of PTFs being immediately applied had been reviewed and properly implemented, and no deletions are effected against any still-active but replaced code [i.e. wanton CLRLIB QRPLOBJ], then there should be no problematic /issues/ with having applied those PTFs.

Permission has been granted for the PTF immediate apply, but I'm
weary <ed: and\or ¿wary?> from previous issues.

Any thoughts from the group.

I often had applied only the immediate-apply PTFs from a set of downloaded requisite PTFs without any difficulties; merely having _scheduled_ an IPL for later in the week when actual down-time could be allotted for the delayed-apply PTFs.
