WebSphere Commerce Version 8.0.4.27 or later

Upgrading WebSphere Commerce (runtime) to WebSphere Application Server bundled Java 8

In this task you will upgrade an existing WebSphere Commerce stand-alone runtime environment to use Java 8. Upgrading to a newer version of Java and WebSphere Application Server will allow you to ensure compatibility and continue receiving product support. The specific version of Java that is run on your runtime will be IBM SDK Java Technology Edition Version 8.0 for WebSphere Application Server.

Before you begin

Ensure that you are planning on upgrading to the latest WebSphere Commerce fix pack. If you are using an older version of WebSphere Commerce, see the previous version of this topic Upgrading WebSphere Commerce (runtime) to Java 8.
You can only update to use IBM SDK Java Technology Edition Version 8 if your existing WebSphere Commerce runtime instance is on WebSphere Commerce 8.0.4.23 or greater. For information about installing fix packs, see Installing maintenance for WebSphere Commerce.
Note: If you have already upgraded your environment to Java 8 before installing this fix pack, you must update the references to Java in your utilities after applying the fix pack (Step 6).
Warning:
- WebSphere Commerce instance creation is not supported with WebSphere Commerce fix packs that require Java 8 until version 8.0.4.30. If you need to create a new WebSphere Commerce instance, you must use WebSphere Commerce 8.0.4.30 or greater. Alternatively, you can use an older Java 7 fix pack, such as 8.0.4.25, before upgrading to Java 8 and a more recent WebSphere Commerce fix pack.
- New instance creation is not supported on IBM i.

Procedure

Upgrade your existing WebSphere Application Server to version 8.5.5.19 or greater.
Note:
- For information about the latest WebSphere Application Server fix packs, see Fix list for IBM WebSphere Application Server V8.5.
- For WebSphere Application Server fix pack installation instructions, see
Stop all WebSphere Commerce servers.

Navigate to the WASInstallDir/bin/ directory and run the following commands to set the command default, set newly created profiles, and set existing profiles, to use the WebSphere Application Server bundled version of the Java 8 SDK. Repeat the existing profile command for each profile that exists.

managesdk.sh -setCommandDefault -sdkname 1.8_64_bundled
managesdk.sh  -setNewProfileDefault -sdkname 1.8_64_bundled
managesdk.sh -enableProfile -profileName WASProfileName -sdkName 1.8_64_bundled -enableServers

For example:

managesdk.sh -enableProfile -profileName demo -sdkName 1.8_64_bundled -enableServers
managesdk.sh  -setNewProfileDefault -sdkname 1.8_64_bundled
managesdk.sh -enableProfile -profileName demo_solr -sdkName 1.8_64_bundled -enableServers

managesdk.bat -setCommandDefault -sdkname 1.8_64_bundled
managesdk.bat -setNewProfileDefault -sdkname 1.8_64_bundled 
managesdk.bat -enableProfile -profileName WASProfileName -sdkName 1.8_64_bundled -enableServers

For example:

managesdk.bat -enableProfile -profileName demo -sdkName 1.8_64_bundled -enableServers
managesdk.bat -setNewProfileDefault -sdkname 1.8_64_bundled 
managesdk.bat -enableProfile -profileName demo_solr -sdkName 1.8_64_bundled -enableServers

Where WASProfileName is the name of the profile that you are modifying.

Note: You can use the managesdk utility script to enumerate the profiles, and verify their Java version.

```
managesdk.sh -listEnabledProfileAll
```
```
managesdk.bat -listEnabledProfileAll
```

Replace the references to Java within your environment.
1. Navigate to the following directory.
  - WC_installdir/bin/
  - WC_installdir\bin\
2. Run the updateJava8 utility script.
  - updateJava8.sh
  - updateJava8.bat
Update the file permissions for the application by running the wcnonroot utility script.
In a command prompt, run the utility:
```
WC_installdir/bin/wcnonroot.sh
```

Results

Your WebSphere Commerce runtime environment is upgraded to use Java 1.8 on a newer version of WebSphere Application Server. This version of Java and WebSphere Application Server ensures continued product support.
