You can use the facilities provided by the Eclipse platform to update your CICS Explorer® software or add new software plug-ins, such as CICS® tools.
CICS Explorer 5.1 introduces the composite update site as a simple way for you to keep up to date with new versions of CICS Explorer and to add new tools and plugins to your CICS Explorer environment. For more information, see Using the composite update site
The update site for the CICS Explorer is already coded in the product. You can see the site address on the Installed Software page in the Software Updates dialog.
If you choose not to use the composite update site, you need to specify the address of your preferred update site, either on your local machine or a remote location. You can add multiple update sites each containing one or more software downloads.
