Hello Shankar,

If you restore the product and actually the prodcut is shown in /var/adm/sw/product you can rebuild the index file by running the followoing command .:

swmodify -a state=configured OS-Core.q4

After that the product will appears in the swlist ..

be sure that you have not corrupt product in your database first.

Hope this helps,

Marco

I assume you are talking about using Software Distributor. Given that, you would swremove ABC, then swinstall XYZ. If XYZ fails, you would swremove it, then swinstall ABC again.

An easier way would be to take an Ignite make_tape_recovery backup of your root VG. Then if XYZ doesn't work out, you simply rebuild your root VG as it was before, with ABC.

You can also take a look at this book:

Explain in detail to how resolve a lot of software issues, and the normal procedures.

Shankar,

I do not think software products works the same way than patches.
First thing to check would be to see if this application can be upgraded or it needs to have a new installation.
If it can be upgrade like ignite or onlinejfs then if something goes wrong just uninstall the later one and you are done.

But the swremove and swinstall option would be the safest way to go.

>Marco: you can rebuild the index file by running the followoing command:

Is this just an example? Or using q4 doesn't matter?

>Jaime: I do not think software products works the same way than patches.

Right. If you install a new version, you can't get the old one back. While you could back up the files, you can't get the IPD to agree with the old files.

>also dont have old software version installation files.
>Let me know any options to get the old software version.

What software is it? You might install the new software to an alternate root, test it there, then remove that alternate root.

Dennis, was not an example! .. I was talking about how to update the INDEX file just in case that you have corrupt products and want to delete them to install the new ones.

This is the command that do that! ...
# swmodify -a state=configured OS-Core.Q4
