Even if you haven't the skills to analyze them, reporting the issue and sending core/crash dumps on request to the software provider is what I would expect in a professional environment.
What you "expect" is not necessarily the requirement of the user.

Professionally, it is better to give options, and let the user decide what is right, based on their configuration and business model.

Many folks turn off dumps, that is why the option is available. You are making the common mistake (again) of expecting everyone else to follow your best practices without knowledge of their business and/or operational model.

Question

Teach the n00b here:

1) I download the patches, first being the 'Sun Patch Alert Cluster'. This is the one I've been starting with on all the boxes I've been patching.

2) Place .zip archive in /tmp, (since the /tmp system seems to be fairly large on each system) and unzip -q them there.

3) 'cd' to the new directory, read the CLUSTER*README, or README files, which contain the instructions and passcodes necessary to continue.

4) Run the ./installer script, watch lots of 'Error code 1 - failed' and 'Error code 0 succeeded' messages go by, sometimes waiting up to 2 hours for the patch to finish.

Does this sound right? Steer me straight here.

Thanks!

A side note: Beware that /tmp available space can be misleading. /tmp is by default (and on your system) backed by virtual memory (a.k.a. swap, a concept sometimes misunderstood). Using this filesystem will be much faster than using a physical disk as long as you have a lot of RAM available. However, if you fill the RAM, then you might have serious performance issue. You can check how much ram is available in KB with this command:
Code:
vmstat 1 2 | tail -1 | nawk '{print $5}'

Most of the patchadd failures are harmless. Common ones are:

- the package for which the patch is intended is not installed so there is nothing to patch
- this patch is already installed
- a newer version of the patch is already there

Before Solaris 10, error codes helped figuring out what was the root cause but it's no more the case unless you use "patchadd -t" option (or edit the installer script to use "patchadd -t" in that case).

Patching can be a lengthy operation. A lot of work is done to make sure the patch installation is consistent and to allow backing out the patch if necessary. If you have zones, the process is even longer as zones have to be activated if not yet booted and patched sequentially.

the only thing i prefer to do (and just to clarify, this my opinion) is to run all patching from single user.

if you perform patching in single user, obviously don't put the patch cluster in /tmp Smilie

ARGH! Still running out of space. :-)

It's just a lab machine, so I'm going for a full-blown re-install.

Meh.

Expanding / from the installation media might be a faster option.
