need to understand and configure vna memory

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

Release : 3.7

Component : Virtual Network Administration

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.

Additional Information

You can monitor the heap usage for VNA using this techdoc:

Make sure your install meets minimum specs:
