IBM Deletion of virtual portal fails with transaction timeout - United States virtual portal; timeout; delete; portlet; EJPAH4000E; EJPEB0804E; rollbackexception; admin; WTRN0006W TECHNOTE (TROUBLESHOOTING)

PROBLEM
Attempt to delete virtual portal via Virtual Portal Manager portlet fails with error:

EJPAH4000E: Failed to delete virtual portal 

Attempts to delete the virtual portal using the ConfigEngine task "delete-virtual-portal" may fail as well.


CAUSE
With the introduction of Managed Pages in WebSphere Portal 8.0, virtual portal deletions require more transaction time when removing from the system. This increased transaction time can lead to an error situation if either of the following timeouts is exceeded: 

 * the total and/or maximum transaction lifetime timeout value(s) for the server 
 * the WCM component's transaction timeout

DIAGNOSING THE PROBLEM
SystemOut.log may show the following: 

Example #1:

RESOLVING THE PROBLEM
1. Increase the total transaction lifetime timeout and maximum transaction timeout values (for example, to 600 seconds or greater) using the instructions in the Related information section below. 

2. If the problem persists after addressing the change in suggestion #1 and the error in SystemOut.log shows that the timeout still occurs after 120 seconds (as opposed to the increased value that you just set), then update to Cumulative Fix (CF) 9 or later to get the fix for APAR PI04872 and then add (or update if already exists) the following custom property to the WCM_WCMConfigService Resource Environment Provider: 

Name: wcm.transaction.timeout 

Value: 600 (for example) 

Note: There is not a target value for a transaction timeouts that applies to every customer environment. The goal should be to find a value that allows the virtual portal deletion to succeed but does not introduce significant delay in being alerted for other transaction timeouts.

Why is my delete virtual portal timing out after 120 seconds? When deleting a virtual portal via the Portal Admin User Interface (UI), it fails to complete. Examination of the SystemOut.log shows the following message:
