Modifying MBean attributes in the Site Configuration window

You can modify some MBean attributes for Rational® ClearQuest® Web server by using the Web Server Options page of the Site Configuration window.

The Rational® ClearQuest® Web server MBean attributes have default values that are suitable for most deployments. As you use Rational® ClearQuest® Web, you might want to modify some of the options in the MBeans to fine-tune performance. For example, some environments allow for higher thresholds and longer run times for backend processes, so these processes might require less frequent recycling.

The Rational® ClearQuest® Web application provides an administrative interface to some Rational® ClearQuest® Web server MBeans. Click Site Administration > Configuration and select the Rational® ClearQuest® Web Server Options tab. You can fine tune the MBean attributes described in Table 1.

MBean attribute Description
Session timeout The amount of time, in seconds, that a user session exists before it times out.
Server work thread count The number of worker threads that each Rational® ClearQuest® RPC server uses to handle requests.
Active HTTP session threshold The number of sessions a single Rational® ClearQuest® RPC server can handle. When this threshold is exceeded, a new Rational® ClearQuest® RPC server is created to handle requests.
Maximum active servers The maximum number of Rational® ClearQuest® RPC servers allowed.
Recycle server HTTP session limit The maximum number of sessions the Rational® ClearQuest® RPC server can handle before it is recycled.
Recycle server lifetime limit The maximum lifetime, in seconds, of a Rational® ClearQuest® RPC server before it is recycled.
Recycle server ONC RPC call limit The maximum number of ONC RPC requests that a backend Rational® ClearQuest® RPC server can process before it is recycled.

Alternatively, you can change these MBean attributes by using the WebSphere® wsadmin command-line tool and Jacl scripting. See Modifying MBean attributes with the wsadmin tool.
