Increasing Search Engine Service Memory Allocation

REMEMBER TO ALWAYS

• Set the minimum and maximum to the same value

• Only ever set the memory pool values to a maximum of half of the available system memory

When you are running OpenSearch as a service, and you want to change the java heap size, editing the jvm.options file in the opensearch\config\jvm.options file has no effect. 

The way to change it when running as a service to run the following from an administrative command prompt from the bin directory of the OpenSearch install.

opensearch-service-mgr.exe //ES//shinydocs-search-engine

if it is a default install, you can run:

"C:\Program Files\Shinydocs Professional\SearchEngine\bin\opensearch-service-mgr.exe" //ES//shinydocs-search-engine

This will pop up a window, and then you can edit the options near the bottom of the Java tab.
