Upgrading the Java SDK to Java SE 8

To upgrade to InfoSphere® MDM 12.0, you must upgrade to Java™ SE 8.

About this task

InfoSphere MDM 12.0 requires Java SE 8.0.

If you are upgrading from InfoSphere MDM 11.5, 11.6.0.0, 11.6.0.1, 11.6.0.2, or 11.6.0.3, then your current installation uses Java SE 6 or Java SE 7. To upgrade your installation, you must first upgrade to Java SE 8.

Note: For new installations of IBM® WebSphere® Application Server 8.5.5.11 or later, Java SE 8 is installed by default.

Procedure

Download and install IBM WebSphere SE Java technology edition 8.0.
For details of the download and installation procedure, see the corresponding WebSphere documentation.
Update to Java SDK 8 for all WebSphere Application Server profiles.
- If your operating system is Microsoft Windows, use the following commands:
```
managesdk.bat -enableProfile -profileName Dmgr01 -sdkname 1.8_64 -enableServers
managesdk.bat -enableProfile -profileName Node01 -sdkname 1.8_64 -enableServers
```
- If your operating system is Linux® or UNIX, use the following commands:
```
managesdk.sh -enableProfile -profileName Dmgr01 -sdkname 1.8_64 -enableServers
managesdk.sh -enableProfile -profileName Node01 -sdkname 1.8_64 -enableServers
```
Note: When InfoSphere MDM is installed on WebSphere Application Server Base edition, do not run the command related to the Dmgr.
When InfoSphere MDM is installed on a WebSphere Application Server cluster, run the command on each of the nodes.
Restart WebSphere Application Server:
- If InfoSphere MDM is installed on WebSphere Application Server Base edition, restart the application server.
- If InfoSphere MDM is installed on WebSphere Application Server ND, restart the deployment manager, nodes, and servers.
- If InfoSphere MDM is installed on a WebSphere Application Server cluster, restart the deployment manager, each of the nodes in the cluster, and the cluster itself.
Verify that the SDK version has changed to SDK 8 on the WebSphere Application Server in the following path:
```
Application servers -- <server_name> --java sdks
```
Proceed with the remaining upgrade steps as normal. See Upgrading to the latest release.
In the mdm_install.properties file, update the property value of user.was.sdk.path.prefix to java_1.8_64.
