Switching to Java 7.0 SDK in WebSphere Application Server

You can switch from Java 6.0 to Java 7.0.

About this task

By default WebSphere Application Server V8.5.5 uses the Java 6.0 SDK, but you can switch to Java 7.0 SDK if required.

Procedure

Stop the WebSphere Application Server.
Install the Java 7.0 SDK by following these instructions: Installing IBM WebSphere SDK Java Technology Edition Version 7.0 using the GUI.
Run one of the following commands, depending on your operating system:
- For UNIX or Linux, run WAS_HOME/bin/managesdk.sh -enableProfile -profileName profilename -sdkname 1.7_64. For example:
```
/opt/IBM/WebSphere/WSRR/v8.5/bin/managesdk.sh -enableProfile -profileName WSRRSrv01 -sdkname 1.7_64
```
- For Windows, run WAS_HOME/bin/managesdk.bat -enableProfile -profileName profilename -sdkname 1.7_64. For example:
```
c:\IBM\WebSphere\WSRR\v8.5\bin\managesdk.bat -enableProfile -profileName WSRRSrv01 -sdkname 1.7_64
```
Start the WebSphere Application Server.
Optional: If you are using Oracle 12C as your database, it is recommended that you use the Java 7 version of the Oracle JDBC driver, ojdbc7.jar. To do this, you must copy ojdbc7.jar from the jdbc/lib directory of your Oracle installation into the WAS_HOME/WSRR/jdbcdrivers/Oracle on your WSRR server. If you are running WSRR in a cluster, you must copy the driver to every server in the cluster, then run the following script. From the WAS_HOME/WSRR/install/jython directory of the WSRR deployment manager, run the oraclejdbc.py script. Supply values for the node and server or cluster:
```
/bin/wsadmin.sh –user username  –password password –lang jython  -f oraclejdbc.py  -cell cellName [-node nodeName -server serverName] | [-cluster clusterName] -javaver 7
```
