  SP2-0864 Session has expired  tips

Oracle Database Tips by Donald BurlesonMarch 29, 2015

Question:  I am getting the iSQL*Plus error "SP2-0864 Session has expired. Please log in again".  How do I prevent the  SP2-0864 error?

Answer:  The Oracle oerr utility show this for the SP2-0864 error:

SP2-0864 Session has expired. Please log in again.

Cause: The iSQL*Plus session was idle for too long and the context has been removed to free resources for other connections.

Action: Reconnect to iSQL*Plus. The system administrator can configure the timeout period.

The Oracle docs note this on Setting the Session Time Out:

Timing out iSQL*Plus sessions helps to reduce machine load and to maximize resources. The time out interval is set by the session-timeout element. It defines the time a session can be idle before it is expired.

You need to stop the iSQL*Plus Application Server to make changes to the session-timeout element. You can edit the web.xml configuration file to change the timeout interval. The web.xml file is located in the directory:

$ORACLE_HOME/oc4j/j2ee/oc4j_applications/applications/isqlplus/
isqlplus/WEB-INF

In the web.xml file, search for the <session-timeout> element inside <session-config>. The syntax of the line to change in the configuration file is:

<session-config>
<session-timeout>15</session-timeout>
</session-config>

Where the value is the number of whole minutes of idle time before the session times out. It has a default value of 15 minutes. It can be set to any value from 1 to 1440 minutes. It can also be set to never expire by entering a negative value such as -1. It should not be set
so small that users do not get a chance to enter their scripts. When a user tries to use a timed out iSQL*Plus session, the Login screen is displayed and the user is prompted to log in again. The following error is displayed: SP2-0864: Session has expired. Please log in again.


Solution: (by Oracle security guru Pete Finnigan)

To prevent the "SP2-0864 Session has expired. Please log in again" error, is related to the iSQL*Plus timeout interval Parameter. You the time out interval with the SQLPlusTimeOutInterval initialization parameter, which the time a session can be idle before it is expired.

You increase the session expiration period you need to edit the iSQL*Plus configuration file isqlplus.conf and change the timeout value:

FastCgiServer ... -initial-env iSQLPlusTimeOutInterval=n

where n is the number of minutes before the session times out. iSQLPlusTimeOutInterval has a default of 30 minutes. It can be set to any value from 1 to 1440 minutes.

The isqlplus.conf file should be included inside the oracle_apache.conf file which in turn is included in httpd.conf file.  Hence, any changes needs a restart of apache to re-read the configuration files:

 $ORACLE_HOME/Apache/bin/apachectl restart
