Patches and Dependencies

[Arne Hillestad]

Can anyone advice me?

Am about to install a Patch that require PHCO_13411 which is superseded by PHCO_23651, depending on PHKL_17869.

PHKL_17869 is superseded by PHKL_18543 which is depending on PHCO_13411.

Where do I start? How to deal with these type of problems? Is the date of posting of importance here?

You should put on both PHCO_23651 and PHKL_18543 at the same time. You can do this by creating a patch depot:

download both patches
unarchive the patches in say /tmp:

sh PHCO_23651
sh

copy the patches to a new depot:

swcopy -s /tmp/PHCO_23651.depot \* @ /tmp/patch.depot
swcopy -s /tmp/PHKL_18543.depot \* @ /tmp/patch.depot

install the patches from the depot

swinstall -s /tmp/patch.depot

Hope this helps.

If youre unsure about which patch needs what as a dependency and what superceedes what, copy all the possible patches into the same depot, and when you install the patch from there it will automatically pull in any/all dependencies and take into account patches which are superceeded. If any are missing or the dependencies/supercession wrong, it will tell you, and you can correct it then retry.

As long as you use the patch_match_target option on swinstall it will work it out for you and save you the worry!

Hi,


I would highly recommend reading the white paper "Patch Management Guide for HP-UX 11.x"
http://docs.hp.com/hpux/pdf/5967-3578.pdf

As far as patch dependencies are concerned, in your case
PHCO_13411 --> PHCO_23651
PHCO_23651 <=> PHKL_17869
PHKL_17869 --> PHKL_18543
PHKL_18543 <=> PHCO_13411 PHKL_17038 PHKL_19169
PHKL_17038 --> PHKL_25188
PHKL_19169 --> PHKL_24027

--> indicates superseded by
<=> dependencies


Now in this case PHKL_18543 is a Mega Patch on which lot of newer patches have a dependency on, so you might need it anyway.

To suffice the dependency needs, you want to download all the patches (PHCO_23651, PHKL_18543, PHKL_25188 PHKL_24027) into a temp directory.

for i in PH*
do
sh $i
done

(This will unshar the patch files and create a patch.depot and patch.text files)

Now to minimize the number of reboots you want to combine them into a single depot.

for i in PH*.depot
do
swcopy -s $i \* @ /path/mypatch.depot
done

Now to install the patches, just do
swinstall -s /path/mypatch.depot

This way you can install all the patches in one shot and minimize the number of reboots to just one.

Again i would highly recommend reading the guide for future needs.

-HTH
