Description Lukas Krejci 2011-06-06 16:05:42 UTC

Description of problem:

If there is a new property in the plugin or resource configuration, it is required to provide a default value in the plugin descriptor otherwise the upgrade of the plugin fails.

I believe that is not the case for all apache plugin properties which can potentially cause problems during upgrade.


Version-Release number of selected component (if applicable):
RHQ 1.3.x to RHQ y

How reproducible:
always

Steps to Reproduce:
1. Inventory some apache instance using RHQ 1.3.1
2. Upgrade the server to RHQ y (where y >= 3), keep the data
  
Actual results:
The upgrade fails

Expected results:
the upgrade succeeds

Additional info:

the workaround is to uninventory the apache instance before the attempt to upgrade

Comment 1 Lukas Krejci 2011-06-21 07:12:12 UTC

This has only been fixed in RHQ 4.1.0-SNAPSHOT so the "y" in the repro-steps needs to be at least that version.

    BZ 711135 - define defaults to all required properties in the apache plugin configuration so that upgrade of the plugin on the server succeeds.

Inventoried Apache in JON231GA build and verified upgrading to Version: 4.1.0-SNAPSHOT Build Number: c57ee65
