committing and uncommitting patches on hpux 11i

Shivkumar — Wed, 07 Dec 2005 00:37:27 GMT

Dear Sirs,

Is there a way for committing and uncommitting a patch on hpux 11i ?

On AIX unix a patch can be uncommitted if found unsuitable.

Thanks,
Shiv

Hi,
I f I understand you correctly, uncommit a patch in HPUX called uninstall and can be done by the command
swremove PATCH_NAME.
This fully deletes the patch from computer, so if you want to "commit" or install it, you need to have its depot and install by
swinstall patch.depot

you can do with swmodify command.

# swmodify -x patch_commit=true PATCH

Refer more on swmodify man page.

#swmodify should help you. Look into swmodify man page for more information.

Also take a look at the command cleanup. It will allow you to commit all patches that have been superseded at least a specific number of times. It's basically a front end to swmodify, but it's a great way to recover space on systems that have been patched a lot.

Hi Shiv

swmodify and swremove options can be used to uncommit the pathces if found unsuitable.

Hi Shiv:

Once a patch is committed it cannot be removed. As noted, to commit you can use 'swmodify'. If a patch hasn't been committed, you can use 'swremove' to remove it.

If you have a stable system, for instance where a set of patches has been applied, there are no problems for several months, and you want to apply another, large set of patches, it is often desireable to "draw-a-line" by committing all patches to form a new baseline:

# swmodify -x patch_commit=true \*

As noted, a less drastic approach is to use 'cleanup' to leave at least one level of predecessor patches to which you can rollback.

Another advantage to committing patches is that you remove the rollback information from '/var/adm/sw' and regain considerable disk space. Balance this, however, against the ability to rollback by not having committed all members of a patch chain.

James; Do you suggest that we should apply patches in uncommited mode first ?
Actually, what is the command to apply patch in uncommitted mode ?

Thanks,
Shiv

Hi Shiv:

Patches are normally applied but not committed unless you explicitly act to commit them as I noted above. That is, a roll-back image, which is a copy of any previous patch or software, is kept in the '/var/adm/sw/save' directory).

If you look at the text notes of any patch in the ITRC Patch Database, you will see something like this, for example:

/*

Run swinstall to install the patch:

swinstall -x autoreboot=true -x patch_match_target=true \
-s /tmp/PHCO_32438.depot

By default swinstall will archive the original software in /var/adm/sw/save/PHCO_32438. If you do not wish to retain a copy of the original software, include the patch_save_files option in the swinstall command above:

-x patch_save_files=false

WARNING: If patch_save_files is false when a patch is installed, the patch cannot be deinstalled. Please be careful when using this feature.

*/

You can read more about patch 'state' here:
