Explanation
Some z/OS connections might not support all of the
views in the z/OS Perspective. For example, an RSE connection, in
the z/OS perspective, might be used for the z/OS Unix File System,
but not for jobs or data sets.
System action
This message is displayed if the z/OS perspective
view is not supported by the currently active z/OS connection.
User response
If you must work with the view that is displaying
the message, switch to a connection that supports the view, for example
the z/OS FTP connection or the ZOSMF connection.
