Hardware, software, file system, and compatibility information
Review the requirements information to identify operating system, file system, and compatibility requirements, prerequisite tasks, and other information required to install or upgrade DevOps Code ClearCase®.
Information about supported operating systems and file systems, including information about basic hardware requirements and operating system patches is available from the ClearCase System Requirements List on the IBM® Support website. The system requirements list provides access to detailed system requirement information for DevOps Code ClearCase by version.
- IBM Installation Manager and IBM Licensing software version requirements
-
- IBM Installation Manager, version 1.9.1 or later fix pack, or version 1.9.2 or later fix pack. For more information, see Installation Manager. See the system requirements for ClearCase for the most up-to-date requirements.
- IBM Licensing Server software, version 9.x. For more information, see Upgrading the IBM License Key Server.
- IBM License Key Administrator, version 9.x or later (only supported on Windows™ systems). For more information, see Installing License Key Administrator.
- Java Runtime Environment (JRE) requirement
-
- For the DevOps Code ClearCase installation,
you must have a 64-bit Java Runtime Environment (JRE) specifically for Java 11
installed before you install ClearCase. During the installation of
ClearCase, you must set the path
to the java executable in your JRE installation if you plan to use any of the
Java-based components for the product. See the list of Java-based components on the
installation panel. ClearCase does
not ship with its own JRE, but instead uses a JRE that is already installed on your
system. If you do not have a JRE already, you can obtain one from Adoptium at https://adoptium.net.Tip: For the initial installation of a JRE, install it in a folder of your choice with a folder name that does not identify the version number for the Java. As an example, use a folder name like "jre" instead of "jdk-11.0.12+7-jre". Later, when you want to install a new updated Java (as an example, jdk-11.0.19+7-jre), install the updated Java into the same file system location as the initial Java. Then no reconfiguration of ClearCase is needed because of the new JRE. For more information, see Reconfiguring ClearCase to use a different JRE.Important: For DevOps Code ClearCase on Windows, you must unpack the JRE locally. Running the JRE from a network location is not supported. During the installation process for DevOps Code ClearCase, you must enter the path to your JRE.
