RHBA-2014:0968 - Bug Fix Advisory

Topic

An updated rhevm-dwh package that fixes a bug is now available.

Description

The Red Hat Enterprise Virtualization Manager data warehouse package provides
the ETL process and DB scripts to create a historic database API. Enables SQL BI
reports creation for management and monitoring.

Changes to the ovirt-engine-dwh component:

• This update ensures that CPU usage statistics for hosts with more than one

core correctly take into account the number of cores on those hosts when
calculating overall CPU usage. (BZ#1098779)

• Previously, the ovirt-engine-dwh-setup command would fail under certain

conditions if the pg_hba.conf file had been manually edited prior to running
that command. This was caused by the setup process checking the exact number of
spaces in between values for lines describing the engine database. Now, the
logic for checking the values in such lines has been revised so that the setup
process can correctly read all values regardless of the number of spaces.
(BZ#1109897)

• Previously, attempting to upgrade from Red Hat Enterprise Virtualization 3.3

to Red Hat Enterprise Virtualization 3.4 using an answer file would fail under
certain circumstances. This was caused by the logic used to perform upgrades in
Red Hat Enterprise Virtualization 3.3, in which it was necessary for the Data
Warehouse database to be installed on the same host and port as the engine
database, and the Data Warehouse database did not keep the host and port in its
own conf file, instead relying on that of the engine database. This would
prevent setup from setting the correct database host and port, causing the
upgrade process to fail. Now, this logic has been updated so that the database
host and port can be correctly set using an answer file, if supplied, making it
possible to perform the upgrade process under these conditions.

Furthermore, users can successfully upgrade from Red Hat Enterprise
Virtualization 3.3 to Red Hat Enterprise Virtualization 3.4 using an answer file
by copying the database host and port from the engine conf file to the Data
Warehouse conf file as follows:

sed -rne 's/^ENGINE_DB_(HOST|PORT)=(.*)/DWH_DB_\1=\2/p' \
< /etc/ovirt-engine/engine.conf.d/10-setup-database.conf \
>> /etc/ovirt-engine-dwh/ovirt-engine-dwhd.conf.d/10-setup-database.conf
(BZ#1100281)

All Red Hat Enterprise Virtualization reports and data warehouse users are
advised to upgrade to this updated package which addresses this issue.
