Patches dependencies and supersedes

[Leo The Cat]

Hi

i'm new in Hp-ux Patches.

What doesn't it mean exactly dependencies in Patches context.

1) In doc patch for PHSS_33277 i can see
patch Dependencies:
s700: 11:23: PHSS_33279
s800: 11:23: PHSS_33279

=> i need to patch first with PHSS_33279. i think not.

2) what is Supersedes ? In doc patch for PHSS_33277 i can see:
Supersedes:
PHSS_31857

Thanks in advance for all welcome answers.
Regards
Den

Hi Den:

A "superseded" patch is a patch that has been replaced by another (later) patch.

A "dependency" of one patch upon another simply means that the patch that can only be installed if the "dependent" patch is already installed or is *being* installed.

If you are new to HP-UX patching, an excellent guide is this:

1) A dependent patch must already be installed or installed at the same time as the patch in question.

2) Sepersedes PHSS_xxxxx means that the current patch includes the fixes in PHSS_xxxxx. This also means that condition 1) can be fulfilled not only by a specific patch but also by any patches that supersede the original dependent patch.

1) Dependencies means that the patch you are looking at also requires that the dependent patches be installed.

In this case patch PHSS_33277 REQUIRES that patch PHSS_33279 be installed as part of the same patch bundle OR already be installed on your system.

2) Supersedes means "in place of" or "instead of" or "replaces". PHSS_33277 can be used instead of PHSS_31857. If PHSS_31857 is already installed on your system, the PHSS_33277 will replace PHSS_31857 and will be show as such in 'swlist' output.

In addition to the guide, take a look at the Software Assistant tool available from https://www.hp.com/go./swa. It can manage patch dependencies for you.

Actually you don't want that old C compiler patch A.06.02. You want to install A.06.10 then patch up to A.06.14, PHSS_35974.
