Applies to:
Oracle Forms - Version 11.1.2.2.0 to 11.1.2.2.0 [Release 11g]Information in this document applies to any platform.
Weblogic Server 10.3.6
Forms and Reports 11.1.2.2
Symptoms
Using Forms 11.1.2.2, the number of Forms User Sessions in Fusion Middleware Control sometimes shows 0(zero) even though there are sessions running. Refreshing multiple times the sessions will sometimes show accurately, but other times shows 0 or no data at all.
Already reviewed the following notes:
<Note: 1532650.1> Number Of Forms User Sessions (frmweb) not Showing in EM Console
<Note: 1376186.1> OPMN Consuming Memory Over Time with "Process Ping Failed" Messages in Logs
<Note: 1390508.1> Forms User Sessions (frmweb) not Displaying in Oracle Enterprise Manager Fusion Middleware Control 11g (EM)
<Note: 1376186.1> OPMN Consuming Memory Over Time with "Process Ping Failed" Messages in Logs
<Note: 1390508.1> Forms User Sessions (frmweb) not Displaying in Oracle Enterprise Manager Fusion Middleware Control 11g (EM)
However, the solution is to apply 11.1.2.1 or higher, but in this case, already using Forms 11.1.2.2.0.
In the AdminServer-diagnostic.log, can see the following error:
