Issue/Introduction
The VNA server is slow since I added several new engines.
Where can I manage how much memory VNA is set to use?
Cause
VNA is a java application that runs ‘within’ Wildfly.
During the install the default memory value is 4g
Environment
DX NetOps Virtual Network Administration any version
Resolution
Since VNA runs ‘within’ Wildfly, we need to look at the memory settings for Wildfly server.
/opt/CA/VNA/wildfly/bin/standalone.conf
if [ "x$VNA_MAX_MEM" = "x" ]; then
VNA_MAX_MEM=4096m
Adjust this value as needed but make sure to leave enough resources for the OS and mysql.
In large environments, set this to 16GB.
Additional Information
You can monitor the heap usage for VNA using this techdoc:

Make sure your install meets minimum specs:
