Memory (RAM) Increase for Large End User Capacity¶
Performance on a VOSS-4-UC installation with less than 16GB RAM may degrade when a large end user capacity is reached.
Memory on unified nodes of a cluster with a database role should be 16GB.
For each site with a multinode cluster, for each non-primary database server:
- Shut down the non-primary database server.
- In VMware, increase the memory for each non-primary database
server node at the site as follows:
- In the Inventory panel, select the virtual machine.
- In the Hardware list on the Summary tab, select Memory > Edit.
- On the Resources tab, Memory > Resource Allocation and ensure the minimum allocation is 16GB.
- Click OK.
- Restart the database server.
- Repeat the process described above for the primary database server.
