Description Scott Herold 2014-06-26 21:46:36 UTC 
Description of problem:
Customer has customized the Java Heap configuration of DWH and increased -Xmx form 1GB to 2GB.  During Z-Stream upgrade from RHEV 3.3.2 to 3.3.3 this setting was reverted to the default, and DWH failed to start in a scale environment.


Version-Release number of selected component (if applicable):
3.3.2 to 3.3.3 Upgrade

How reproducible:
100%

Steps to Reproduce:
1.  Upgrade DWH during RHEV-M upgrade
2.  Check Java Heap settings for DWH

Actual results:
Heap reverts to default setting

Expected results:
User-defined heap value is retained across upgrades

Scott - How did they do that? Edited [1]? I do not see any other way. Do we have an article/doc recommending to do that?

[1] /usr/share/ovirt-engine-dwh/etl/history_service.sh

Thanks!

For reference:

In 3.3: RUN_PROPERTIES="-Xms256M -Xmx1024M" in  /usr/share/ovirt-engine-dwh/history_services.sh

In 3.4: DWH_JVM_ARGS="-Xms256M -Xmx1024M" in a .conf file at /etc/ovirt-engine-dwh/ovirt-engine-dwhd.conf.d directory
