Previously, the Java heap size for Data Warehouse was not explicitly set. This resulted in the Java virtual machine using the default size, which could have been as large as a quarter of the machine’s total memory. With this release, Data Warehouse’s configuration was updated to allocate 1 GB of RAM, with the addition of two new parameters:
DWH_HEAP_MIN=1g
DWH_HEAP_MAX=1g
The size can be set to a higher value for larger environments using these new parameters.

Description

Can you provide any additional information what will be contained within this RFE? Should we consider scale environment or just standard setup, clean DWH or under load? Can we define here what's the criteria for the RFE? What is the desired result? (In reply to Lukas Svaty from comment #1) > Can you provide any additional information what will be contained within > this RFE?

Essentially running the JVM in a similar manner to how the engine is running (XMS and XMX setting for Java). > > Can we define here what's the criteria for the RFE? What is the desired > result? Less (virtual) memory usage, hopefully better CPU utilization. We'll test these on RHEV.TLV (which is using the full mode DWH. Please test this by adding a new conf file to ovirt-engine-dwhd.conf.d : DWH_JVM_ARGS="-Xms1g -Xmx1g" and restart dwh service. Please how this affects the resources utilization on a scale environment. Also this should not affect production environment so can be tested on an internal production environment. It can be tested on a 4.0 environment as well. Opened separate bug for limiting heap size testing. Shirly - I believe this can be moved to ON_QA now? all the dependant bugs in verified moving this as well |
