Question:
How is memory allocated to the services in the Agile Central on-premises appliance?
Answer:
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
