The Snaplex Linux installers include a bundled OpenJDK-based JRE 11 distribution. You can follow the instructions in this document to change the Java version on your Linux and Windows Snaplex instances. You might need to change the Java version to update the JRE in order to receive security and functionality fixes in the newer JRE distribution. Even if your organization has a license for a different JRE distribution, you can use the procedure in this article to configure the Groundplex to use the said JRE.

We support only Java 11-based distributions; Java 12 or newer versions are not yet certified by SnapLogic. Java 8 or earlier versions are not supported. |

- Custom trust store entries: The JRE uses a cacerts trust store file at <JAVA_HOME>/lib/security/cacerts that has the trusted root certificates. If there are Snap endpoints that are using certificates signed by other providers, then the providers need to be added to the cacerts file. The update needs to be done every time the JRE version is updated or when a new node is being provisioned.
- ulimit changes: If the file and process limits are customized, then the the changes have have to be applied again when when a new node is being provisioned to the Snaplex.
- Custom binaries: Some Snaps require customer binaries to be installed on the Snaplex node, like native libraries for SAP and bulk loading tools for database Snaps. These changes have to be applied manually when a new Snaplex node is being provisioned.
