ICX Timeout Profile Values

ICX:Session Timeout - This profile option determines the length of time (in minutes) of inactivity in a user's form session before the session is disabled. Note that disabled does not mean terminated or killed. The user is provided the opportunity to re-authenticate and re-enable their timed-out session. If the re-authentication is successful, the disabled session is re-enabled and no work is lost. Otherwise, the session is terminated without saving pending work. This functionality is available via Patch 2012308 (included in 11.5.7, FND.E). Note: Setting the profile value to greater than 30 minutes can drain the JVM resources and cause ‘out of memory’ errors.

ICX: Limit time - This profile option defines the maximum connection time for a connection – regardless of user activity. If 'ICX:Session Timeout' is set to NULL, then the session will last only as long as 'ICX: Limit Time', regardless of user activity.

ICX: Limit connect - This profile option defines the maximum number of connection requests a user can make in a single session. Note that other EBS internal checks will generate connection requests during a user session, so it is not just user activity that can increment the count.

Parameter	Default	Recommendation
ICX:Session Timeout	None	30 (minutes)
ICX: Limit Time	4 (hours)	4 (hours)
ICX: Limit Connect	1000	2000

Change Idle Session timeout ICX Session Timeout session.timeout(http://becomeappsdba.blogspot.com/2006/09/change-idle-session-timeout-icx.html)

If someone ask Apps DBA to change Session Idle Time out value How & where will you change ? In order to answer first you have to understand what kind of seesions are in Apps 11i and what is Idle timeout ? In Apps there are two broad categories of session - Self Service Application Session ( Server by Web Server iAS Apache & Jserv, like iRecruitment, iProcurement) -Forms session ( served by your form session, like system Administrator) What is Session Idle time ? If Oracle Apps client is not doing any activity for some time (when application user goes for coffee or talks over phone) session during that time is called as Idle Session & because of security reason, performance issues and to free up system resource Oracle Applications terminates client session( both forms & self service) after idle time value is reached to the one mentioned in configuration file. From FND.G or 11.5.9 or with introduction of AppsLocalLogin.jsp to enter into application, profile option "ICX Session Timeout" is used only to determine Forms Session Idle timeout value . This might be confusing as earlier this profile option used to control forms as well as self service application(with session.timeout) session.timeout is used to control Idle session timeout for Self Service Applications ( Served by Jserv via JVM ) From where ICX : Session Timeout & session.timeout get values ? Autoconfig determines value for profile option "ICX: Session Timeout" and "session.timeout" from entry in context file ( $APPL_TOP/admin/SID_hostname.xml ) with parameter s_sesstimeout where value mentioned is in milliseconds so profile option ICX: Session Timeout value should be s_sesstimeout/ (1000 * 60) which means here its 10 Minutes. This value is also set in zone.properties in $IAS_ORACLE_HOME/Apache/Jserv where number mentioned is in milli second i.e. 600000 ( equal to 10 Minutes)session.timeout = 600000 session.timeout mentioned in zone.properties is in milli secondsICX Session Time out mentioned in profile option ICX: Session Timeout is in minutes so ICX session timeout=30 & session.timeout= 1800,000 are same 30 minutes P.S. ICX Session time out was introduced in FND.D so if your FND version is below D you might not see this variable. Important Things Apps DBA should consider while setting session timeout value ? 1.. If you keep session.timeout value too high , when some oracle application user accessing Self service application terminates his session, so longer idle session will drain JVM resource & can result in Java.Lang No Memory available issues . 2. If you keep it too low, users going out for tea or sitting idle for some time have to login again into application & can be annoying . Thumb rule is session time out usually set to 30 minutes.
