Hi - I would greatly appreciate any help in understanding the timing of when I
have access to the original or updated version of files installed during a
patch install, uninstall and rollback sequences of both.
The Install process seem fairly straight forward. I have availability of the
old files before the InstallFiles sequence and the new ones afterwards.
However when a rollback occurs I am not sure at what point I have access to the
newly installed files and the original files before the patch was applied?
Can I schedule something to have access to both the current and previous
versions?
The Uninstall of the patch seems even a little more confusing since it appears
that the previous files are restored before I can get a custom action to run.
But once a rollback occurs do I have access to the current or previous versions?
The following example is what I am trying to work out. I am installing both
SSRS & SQL content on a server and need to handle both the Installation and
Un-installation of a patch as well as handling a rollback occurring during
either. The Desired Action column shows what I want to happen I just need to
know when I have availability to the desired version so I can call the
appropriate CA to perform the action.
Assuming:
Base Install - puts V1 of files on server
Patch1 - puts V2 of files on server
Install Operation
Schedule
Desired Action
Install Patch1
After InstallFiles
Run CA to put V2 reports on server
Run InstallV2.sql
Rollback occurs during Install Patch1
?
Run CA to put V1 reports on server
Run Uninstall V2.sql
Run InstallV1.sql
Remove Patch1
?
Run CA to put V1 reports on server
Run Uninstall V2.sql
Run InstallV1.sql
Rollback occurs during Remove Patch1
?
Run CA to put V2 reports on server
Run InstallV2.sql
Thanks - Tom
