Configure custom memory settings for OpenSearch (upgrading traditional to KOTS)
To prepare for installing Jama Connect, you must first update the system that hosts the application. The update consists of configuring memory settings for OpenSearch.
Requirements
The memory settings must be configured on each server in the KOTS cluster for OpenSearch to run on these servers. If you use the remote OpenSearch setting, the memory settings can be applied only to servers that are dedicated to OpenSearch.
You must have admin permissions to configure the memory settings for OpenSearch.
To configure memory settings:
As an admin, open the /etc/sysctl.conf file, add the following line to the file, then save the file.
vm.max_map_count=262144
Reload the sysctl.conf file:
sudo sysctl -p
To confirm, type this command:
sudo sysctl -a | grep max_map_count
The system responds with:
vm.max_map_count=262144
The memory settings on your system are now configured for OpenSearch.
