Tamino X-Plorer documentation will likely help:
http://techcommunity.softwareag.com/ecosystem/documentation/webmethods/tamino/ins97/xplorer/xplover.htm
For CentraSite RR, use http://host:port/CentraSite as the Server URL, with CentraSite as the Database. No configuration from inoadmin required. Once you have connected to the CentraSite database with X-Plorer, you can use the tree directory to browse through the various collections there.
Be aware: you can update the data from X-Plorer, but this is obviously not a good idea to do!
