I think that the Clearcase server is also used for hosting the view server, but how can I be sure?
#cleartool hostinfo -long
Client: abcd123
Product: ClearCase 8.0.1.4
Operating system: AIX 1 7
Hardware type: 00C7D6164C00
Registry host: abcd123
Registry region: ggg
License host: abcd123.kalzam.razel.steria.ch
As described in "Rational ClearCase server processes", a view_server is a long-lived process that manages activity in a particular view.
So if you see any view_server process on a given host, then that host is a view server.
But that does not mean it is the only one, and any ClearCase client can also hosts its own view (if ClearCase was installed with a view server as part of its features)
See also cleartool lsstgloc for listing registry information about server storage locations for views, VOBs, or both.
cleartool lsstgloc -view -host anHostname
If that returns something, then 'aHostname' is a view server.
If you have a view tag in mind, describe it to get its view storage path:
cleartool lsview -l -full -pro aViewTag
From that global path, you can get the view server hostname with:
cleartool lsstgloc -view -long -storage a/global/path
Type: View
