This article explains how to change the memory settings for the OrientDB database.
All supported Test Data Manager releases.
Update this file C:\Program Files\CA\CA Test Data Manager Portal\service\conf\orientdb.conf (or whatever drive you installed TDM Portal on).
Uncomment this line for minimum memory and change to the minimum value you want - Initial Java Heap Size (in MB)
#wrapper.java.initmemory=3
Uncomment this line for maximum memory and change to the maximum value you want - Maximum Java Heap Size (in MB)
#wrapper.java.maxmemory=64
You will have to restart the OrientDB service.
You can configure the values of TDM Helm Chart according to your Kubernetes system setup in the values.yaml file. After configuring, use the updated values.yaml file for the TDM Deployment on your Kubernetes cluster using Helm Chart.
NOTE: Refer to section "Configure values.yaml File" in the documentation of the version of TDM you are running.
