Description of problem:
ovirt-engine should use java-1.7 instead of java-1.6.

Comment 2 Juan Hernández 2012-07-04 14:12:44 UTC

When/if the following change is fixed the engine will refuse to start if the Java virtual machine currently selected with alternatives is not 1.7:

http://gerrit.ovirt.org/#/c/5894

However, this will not fix the issue.

I see two ways to fix it:

1. Change the RPM or the setup tool so that the alternatives command is used to select 1.7 by default. This has then inconvenient that the user can later use the alternatives command to change back to 1.6, maybe for other application, and the engine will refuse to start next time.

2. Change the start script (and the manage-domains and config tools) so that it uses 1.7 regardless of what is configured with alternatives.

Comment 3 Oded Ramraz 2012-07-11 20:39:43 UTC

I lost a lot of time today during si9.1 installation until I realized I'm not using the correct java version:

After I looked at the installation logs I realized that  rhevm-setup fails when it tries to use rhevm-config script: 

2012-07-11 22:57:03::DEBUG::common_utils::309::root:: Executing command --> '/usr/share/ovirt-engine/engine-config/engine-config -s CAEngineKey=/etc/pki/ovirt-engine/private/ca.pem --cver=general -p /usr/share/ovirt-engine/conf/engine-config-install.properties'

    raise Exception(output_messages.ERR_FAILED_UPD_VDC_OPTIONS%(sys.exc_info()[1]))
Exception: Failed updating configuration parameter: Error: failed updating configuration field CAEngineKey to /etc/pki/ovirt-engine/private/ca.pem

When i tried to run rhevm-config manually I've got the same error:
[root@wheat-vdc ~]# rhevm-config  --list
org.apache.xpath.domapi.XPathStylesheetDOM3Exception: Prefix must resolve to a namespace: urn:jboss:domain:datasources:1.0

Only after I run the following command i managed to install the setup properly :
alternatives --set java /usr/lib/jvm/jre-1.7.0-openjdk.x86_64/bin/java

Setting / Raising the severity of this issue.

Comment 4 Juan Hernández 2012-07-12 07:57:29 UTC

Note that the errors that you were getting before running that "alternatives" command where probably caused because you had the IBM J9 virtual machine installed. That is a 1.7 virtual machine, so even if we fix this bug (as described in comment #2) we will still have the same problem.

We can redefine this bug as "ovirt-engine should use openjdk 1.7 regardless of what is installed and configured with alternatives". That or open a new bug.

Comment 5 Juan Hernández 2012-07-12 07:58:38 UTC

Another direction, and maybe another low priority bug, could be to make sure that the engine can work with the IBM J9 java virtual machine (version 1.7, of course).

The suggested solution for this problem is here:

Comment 7 Juan Hernández 2012-07-26 11:02:20 UTC

The change is already merged upstream:
