ORACLE inactive session

-
Lot of inactive session exists in oracle database.

Set the parameter in sqlnet.ora file
Use parameter SQLNET.EXPIRE_TIME to specify a the time interval, in minutes, to send a probe to verify that client/server connections are active. Setting a value greater than 0 ensures that connections are not left open indefinitely, due to an abnormal client termination. If the probe finds a terminated connection, or a connection that is no longer in use, it returns an error, causing the server process to exit. This parameter is primarily intended for the database server, which typically handles multiple connections at any one time.


Default
0
Minimum Value
0
Recommended Value
10
Example
SQLNET.EXPIRE_TIME=10
