ibmint specify jre command

Use the ibmint specify jre command to specify which Java Runtime Environment (JRE) to use for a specified integration server.

Usage notes

The ibmint specify jre command can be used to specify a Java version that is compatible with the content that is already deployed to the integration server. If the specified JRE version is not compatible with the previously deployed content, or if it is incompatible with the optimization of an independent integration server (configured by using the ibmint optimize server command), the command fails.

For more information about restrictions that apply to the use of some message flow nodes and types of security configuration with specific versions of the JRE, see Limitations for JRE versions in IBM App Connect Enterprise.

Parameters

--default
Use this parameter to specify the default JRE version. By default, integration servers use Java 17.
--version version
Use this parameter to specify which JRE version to use. Java 8 and Java 17 are available. By default, integration servers use Java 17.
--work-directory directory
Use this parameter to specify the working directory of the independent integration server that uses this JRE.
--integration-node nodeName --integration-server serverName
Use this parameter to specify the node-managed integration server that uses this JRE.
--trace filePath
Send a verbose internal trace to the specified file.
--verbose
Generate more verbose messages.
--help
Output the command help information to the console.

Examples

Use the default version of Java for the independent integration server with the work directory C:\myServerWorkDir:
ibmint specify jre --default --work-directory C:\myServerWorkDir
Use Java 8 for a node-managed integration server and generate verbose output:
ibmint specify jre --version 8 --integration-node nodeName --integration-server serverName --verbose
In the previous example, you specified Java 8 for your integration server. You can revert to using the default version by running one of the following commands:
ibmint specify jre --version 17 --integration-node nodeName --integration-server serverName
ibmint specify jre --default --integration-node nodeName --integration-server serverName
