Considerations For Effective Usage Of Physical Memory On Dom0 Compute Nodes When Starting Guest vServers In Exalogic Virtual Racks (Doc ID 2068096.1)

Last updated on NOVEMBER 14, 2022

Applies to:

Oracle Exalogic Elastic Cloud Software - Version and later
Linux x86-64
Oracle Virtual Server x86-64


There are situations when during restart of the complete Exalogic rack, there could be issues of not being able to start a guest vServer due to insufficient memory available on a Dom0 compute nodes.

Overall total memory on all the compute nodes part of OVS pool shows sufficient memory available within the rack. This Note explains the procedure to effectively manage and use the physical memory available within the rack by re-arranging the placement of vServers creating enough memory available on the compute nodes. Using this approach should allow users to accommodate more guest vServers. This helps in effectively utilizing the available memory resources to the maximum potential.
