(v22) Configure Memory Settings

Configure Memory Settings

To change memory allocation settings for Composer microservices:

1. From your terminal, SSH to your Composer server.

2. To modify the memory settings for Composer microservices, you need to edit or create the corresponding .jvm files in /etc/zoomdata/. Perform the following steps:

   vi/etc/zoomdata/<component_name>.jvm

   For complete information on editing configuration files, see Edit a Composer Configuration File.

3. Add or update the following line(s) in the corresponding .jvm files.

   Do not allocate more than 85% of your total system memory to all microservices.

   The following example configures the Composer server to use 20 GB of RAM in the zoomdata.jvm configuration file. You can adjust the number to fit your system's needs. Replace the 20 with the necessary memory allocation for your operating environment.

   -Xms20g
   -Xmx20g

4. Save and exit the .jvm file.

5. Restart the microservice for which you have modified the settings:

   For CentOS 7 Ubuntu 18 or 20:

   sudo systemctl restart <service-name>

Wait a few minutes for the microservice to restart completely, then open a new browser window to log back into Composer.
