I have used an FMCINTERNOOP activity as the first activity in my process model followed by other UPES and manual activities. In sporadic cases I find the process instance to be in the running state but not proceeding to the second activity. When i monitor the process using the workflow web client, it shows the FMCINTERNOOP in the running state and the process does not flow furthur. Iam not sure why such a case arises. The activity is a NOOP acitivity and furthur it is set to be asynchronous, this being the case the process should have continued. The worst part is it happens very sporadically. Iam using WF 3.4 in solaris. Any suggestions please? Will setting an expiry time for the NOOP activity help? Could this be due to large data being passed to workflow.


The related FDL is as below
PROGRAM_ACTIVITY 'ACCEPT DATA' ( 'WORKITEMDATA', 'WORKITEMDATA' )
START AUTOMATIC WHEN AT_LEAST_ONE CONNECTOR TRUE
EXIT AUTOMATIC
LAYOUT XPOS -500 YPOS 100
NAME_POSITION XPOS -500 YPOS 25
PRIORITY DEFINED_IN INPUT_CONTAINER
DONE_BY PROCESS_ADMINISTRATOR
PROGRAM 'FMCINTERNALNOOP'
PROGRAM_EXECUTION_UNIT 'EMPTY.FMCSYS1.FMCGRP1'
SYNCHRONIZATION CHAINED
END 'ACCEPT DATA'

PROGRAM 'FMCINTERNALNOOP'
STRUCTURES_FROM_ACTIVITY
UNATTENDED
END 'FMCINTERNALNOOP'

SERVER 'EMPTY'
RELATED_GROUP 'FMCGRP1'
RELATED_SYSTEM 'FMCSYS1'
TYPE USER_DEFINED_PROGRAM_EXECUTION_SERVER
MQSYSTEM MQSERIES
MESSAGE_FORMAT XML
PHYSICAL_QUEUE_NAME "EMPTY"
VERSION 3
RELEASE 3
LEVEL 0
END 'EMPTY'

Is it possible that the Queue is defined?

Hi, your FDL didn't show the control flow from the NOOP activity to the next one(s). If there is the possibility that no one of the exit conditions gets true the navigation of your process won't continue. If you have applied SP4 your NOOP activity goes into state 'InError' and you won't be able to continue process flow.

You can check this by monitoring the NOOP Activity via the WebClient.
Always ensure that your process model contains an OTHERWISE control
path that gets true if no other exit condition gets true!
