You can install WebSphere® Application Server Version 8.5 using the Installation Manager command line.
Before you begin
![[8.5.5.11 or later]](https://www.ibm.com/docs/en/SSEQTP_8.5.5/com.ibm.websphere.installation.base.doc/images/ng_v85511.gif)
- 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.
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.
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.
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.
Prepare the system onto which you want to install the product as described in Installing Installation Manager and preparing to install the product.
