Issue/Introduction

How is memory allocated to the services in the Rally on-premises appliance?

Environment

Release:
Component: ACPREM

Resolution

There are 4 primary consumers of memory in the on-premises appliance:

• Oracle
• ALM
• Analytics
• SOLR

 

Oracle

We reserve 3 GB of memory for the Oracle processes
 

ALM

ALM memory is computed at run-time.  The formula is as follows:

memory = (total_system_memory - 3000) * .6

The default setting of 8 GB of system memory will leave 3 GB for ALM.  Increasing the system memory to 12 GB will allow ALM to use up to 5.4 GB.
 

Analytics

Analytics receives a static 512 MB of memory
 

Solr

Solr receives a static 256 MB of memory
