Learn how to upgrade the Java version of your LCA functions in AWS Lambda.

1. Select LCA Function
   In AWS, select the LCA function you want to upgrade the Java version:
   1. Open the AWS Lambda console.
   2. Navigate to the Functions page.
   3. From Function name, select the function for Java upgrade.

      

2. Upgrade Java version:
   1. In Code > Runtime settings, select Edit.

      

   2. Under Runtime , change the Java version to Java 21.
   3. Select Save.
3. Verify the upgrade:
   Check to see if the LCA function is invoked.
   Attention: If the LCA is not invoked, check the Lambda logs for errors. For assistance, contact Reltio Support with the logs and a screenshot of the runtime settings. Until Reltio fixes the issue, downgrade the LCA function to the previous Java version.
