Setting the Time to Expire for Idle Oracle BI Presentation Services Client Connections

The entry ConnectionExpireMinutes defines the length of idle time that the connection between Oracle BI Presentation Services and the Oracle BI Server is maintained before the connection is closed. You can override the number of minutes to elapse by modifying the Oracle BI Presentation Services configuration file (instanceconfig.xml) to add the following entry. The internal default is 3 minutes.

The following entry is an example:

<ConnectionExpireMinutes>3</ConnectionExpireMinutes>

When a user logs into the Analytics application, a connection is created from the browser client to Oracle BI Presentation Services, and another connection is created from Oracle BI Presentation Services to the Oracle BI Server. If the user's session remains idle for three minutes or more (the user does not perform any operation), the connection from Oracle BI Presentation Services to the Oracle BI Server is closed or dropped. The connection from the browser to Oracle BI Presentation Services still remains intact. The next time the user performs an operation such as running a report or navigating to a dashboard, a new connection is created from Oracle BI Presentation Services to the Oracle BI Server.

NOTE:  This setting affects idle time only. For example, if the user were to run a request that executes for more than three minutes, the original connection from Oracle BI Presentation Services to the Oracle BI Server remains intact throughout, until the three-minute idle time is encountered again. This setting therefore keeps down the number of open connections to the server.

You can also set the amount of time to elapse before a user is logged off automatically. For more information, read Setting the Time to Log Users Off Oracle BI Presentation Services Automatically.
