Oracle Timing Options

An optional parameter can be added to the Oracle Server’s sqlnet.ora file to monitor session activity. If an HPD client session has been inactive for N minutes, the Oracle session is closed.

1. In sqlnet.ora, type the following parameter:

sqlnet.expire_time=5

In the above example, Oracle sends out pings every five minutes to see if the HPD client session is still active. If the HPD applications are still open, the Oracle session is not terminated even if the applications are idle.
