Completing the OSK DPK Post-Installation Steps

After you complete the OSK DPK installation, if you want to perform operations described later in this chapter, such as starting and stopping OpenSearch, or running the opensearchuser script, perform the manual steps described in this section.

• Ensure that the heap size is set to a value equal to or less than 50% of available memory, and not exceeding 30G.

  See "Preparing to Deploy," Prerequisites.

• Verify that the JAVA_HOME environment variable was set to the location installed by the DPK setup script. If not, set it, for example:

  set JAVA_HOME=BASE_DIR\pt\os_jdk21.0.yy
