Installing and uninstalling SDK Java Technology Edition Version 7.0 or 7.1 on distributed operating systems

IBM® WebSphere® SDK Java™ Technology Edition Version 6.0 is no longer in service. Using IBM Installation Manager, you can optionally install IBM WebSphere SDK Java Technology Edition Version 7.0 and 7.1., which are in service until July 2022. For new installations of WebSphere Application Server 8.5.5.11 or later, Java SE 8 is installed by default.

Before you begin

Attention: Starting in version 8.5.5.11, the default versions of Java are Java SE 6 or Java SE 8. As such, you can accept the default and install either Java SE 6 or Java SE 8 as the version of Java SE contained in the /java and /java64 directories in WebSphere Application Server and used by default during server and node configuration. Java 8 is the recommended Java SDK because it provides the latest features and security updates. You can continue to use Java SE 6, but no service can be provided after the end of support in April 2018, which might expose your environment to security risks.

Java SE 7 and Java SE 7.1 (not available for Solaris and HP) are also viable options for installing on WebSphere Application Server version 8.5.5.11.

The bit level of Java SE 7.0 is based on the bit level selected during the initial installation of WebSphere Application Server. If a 32-bit WebSphere Application Server is installed, then only the 32-bit Java SE 7.0 can be installed. If a 64-bit WebSphere Application Server is installed, then only the 64-bit Java SE 7.0 can be installed.
Installing the optional Java SE 7.0 or Java SE 7.1 does not imply that profiles can take advantage of this new version of Java. The managesdk command can be used to switch Java or the WebSphere Application Server administrative console (wsadmin) can be used to make the switch.

[8.5.5.14 or later] Starting in version 8.5.5.14, Java SE 8 is the default Java. When updating to 8.5.5.14, any existing profile that uses Java SDK 6 is replaced by Java SDK 8. You can continue to use Java SDK Java Technology Edition Version 7.0 and Version 7.1, but no service can be provided after the end of support in July 2022, which could expose your environment to security risks.

For more information on Java SE 6, 7, and 7.1 end of service, see Java SE 6, 7, and 7.1 end of service in WebSphere Application Server V8.5.

The com.ibm.websphere.IBMJAVA.v80 offering will be deprecated, and no fix packs or interim fixes will be provided for this offering after March 2020. If this offering is installed with WebSphere Application Server Version 8.5.5 after March 2020, uninstall it and switch to the default Java SE 8 SDK provided by the WebSphere Application Server package in the same package group. With the default Java SE 8 SDK, you continue receiving Java SE 8 SDK support, including security updates.

[8.5.5.18 or later] Starting in version 8.5.5.18 for Linux on POWER8 Little Endian (LE), the default versions of Java are Java SE 7.1 or Java SE 8. As such, you can accept the default and install either Java SE 7.1 or Java SE 8 as the version of Java SE contained in the /java directory in WebSphere Application Server and used by default during server and node configuration. Java 8 is the recommended Java SDK because it provides the latest features and security updates. You can continue to use Java SE 7.1, but no service can be provided after the end of support in July 2022, which might expose your environment to security risks.

You can use the user.wasjava=java8 property only with new installations of the product for Linux on POWER8 LE. The user.wasjava=java8 property does not work for product upgrades through fix packs for Linux on POWER8 LE.

[8.5.5.19 or later] Starting in version 8.5.5.19 for Linux on POWER8 Little Endian (LE), the default version of Java is Java SE 8. As such, you can accept the default and install Java SE 8 as the version of Java SE contained in the /java directory in WebSphere Application Server and used by default during server and node configuration. You can continue to use Java SE 7.1 by installing IBM WebSphere Java SDK Version 7.1, but no service can be provided after the end of support in July 2022, which might expose your environment to security risks.

The user.wasjava=java8 property is not required for installing and updating to version 8.5.5.19 for Linux on POWER8 LE.

Avoid trouble: Installing SDK Java Technology Edition Version 7.1 on a Red Hat 5 Linux or SUSE 10 Linux distributed operating system is an unsupported configuration.

Note: WebSphere Application Server Version 8.5.5.2 and later support IBM WebSphere SDK Java Technology Edition Version 7.1. This package is not available on the product media or on IBM Passport Advantage®.

You can install or uninstall IBM WebSphere SDK Java Technology Edition Version 7.0 or 7.1 for the following offerings:

Application Client for IBM WebSphere Application Server
DMZ Secure Proxy Server for IBM WebSphere Application Server
IBM WebSphere Application Server
IBM WebSphere Application Server Trial
IBM WebSphere Application Server - Express®
IBM WebSphere Application Server Network Deployment
IBM WebSphere Application Server Network Deployment Trial
IBM WebSphere Application Server for Developers
IBM WebSphere Application Server for Developers (ILAN)

Restriction:

Installation Manager console mode, which is included in Installation Manager Version 1.4.3 and later, does not work with WebSphere Application Server Version 8.5 offerings on systems other than z/OS®.
The Installation Manager web interface, which is included in Installation Manager Version 1.8.0 and later, does not work with WebSphere Application Server Version 8.5 offerings.

About this task

Note: The IBM Installation Manager is now used to install, maintain, and uninstall IBM WebSphere SDK Java Technology Edition Version 7.0 or 7.1.

Perform one of these procedures to install, update, roll back, or uninstall IBM WebSphere SDK Java Technology Edition Version 7.0 or 7.1 using Installation Manager.

Note: For information on installing and removing fix packs for WebSphere Application Server offerings on distributed operating systems using the Installation Manager command line, read the following topics:

Procedure

Results

Notes on logging and tracing:

An easy way to view the logs is to open Installation Manager and go to File > View Log. An individual log file can be opened by selecting it in the table and then clicking the Open log file icon.

Logs are located in the logs directory of Installation Manager's application data location. For example:

Administrative installation:

C:\Documents and Settings\All Users\Application Data\IBM\Installation Manager\logs

Non-administrative installation:

C:\Documents and Settings\user_name\Application Data\IBM\Installation Manager\logs

Administrative installation:
```
/var/ibm/InstallationManager/logs
```

Non-administrative installation:

user_home/var/ibm/InstallationManager/logs

The main log files are time-stamped XML files in the logs directory, and they can be viewed using any standard web browser.
The log.properties file in the logs directory specifies the level of logging or tracing that Installation Manager uses.

Notes on troubleshooting:

By default, some HP-UX systems are configured to not use DNS to resolve host names. This could result in Installation Manager not being able to connect to an external repository.
You can ping the repository, but nslookup does not return anything.

Work with your system administrator to configure your machine to use DNS, or use the IP address of the repository.
For more information on using Installation Manager, read the IBM Installation Manager documentation.
Read the release notes to learn more about the latest version of Installation Manager. To access the release notes, complete the following task:
- Click Start > Programs > IBM Installation Manager > Release Notes®.
- Go to the documentation subdirectory in the directory where Installation Manager is installed, and open the readme.html file.

What to do next

Tip: Run the managesdk command to switch the SDK used by commands and server profiles.

Note: If you install IBM WebSphere SDK Java Technology Edition Version 7.0 or 7.1 and then remove it later and there are profiles or commands still using these Java versions, you will see errors. You can re-install IBM WebSphere SDK Java Technology Edition Version 7.0 or 7.1 to fix these errors.
