Some system configuration tasks require you to temporarily stop EPX processing. When EPX is paused, no new work items will be created and no EPX activities will process existing work items. After the system configuration task is complete, resume EPX processing.
Pause EPX processing
The best way to pause EPX processing is to stop the EPXTomcat service.
Individual workflows should not be modified directly to stop the generation
of new work items, as this only addresses the creation of new work items and does
not address the processing of work items already in workflows. Modifying individual
workflows also introduces the significant risk that when EPX processing is resumed,
one or more workflows will not be restored to use the same settings they used before
EPX processing was paused. For example, if a Scheduler BIC starting point that is
configured to launch once per day is disabled and then later enabled, the settings
for that BIC will revert back to their default settings, which will causes one work
item to be generated per minute, which can be disastrous. Stopping the
EPXTomcat service pauses all EPX activity without altering
workflows.
To pause EPX processing:
- Open the Windows Services control panel.
- Right-click
EPXTomcatand select Stop. - Once the
EPXTomcatservice is stopped, the Status column for theEPXTomcatservice will no longer have the value Running. The value will be empty.
Resume EPX processing
To resume EPX processing:
- Open Windows File Explorer and go to:
<drive>:\Enterworks\bin - Right-click
Stop EPX.cmdand select Run as Administrator. This will stopEPXTomcatandEPXJboss. - Right-click
Start EPX.cmdand select Run as Administrator. This will archive EPX logs and restartEPXTomcatandEPXJboss. - A command prompt will appear that indicates that the services are starting. The prompt will close once the services have been started.
- Verify that
EPXTomcatandEPXJbossare both running. Open the Windows Services control panel and verify that the Status column for both services has the value Running.
