There is a way to restart just the UBE queue in EnterpriseOne. If you are faced with a situation where submitted jobs are not processing and the jobs are sitting in a waiting status you can get the queue restarted without bringing down the entire E1 system, allowing interactive users to continue their work.
In older (prior to 8.9) releases the queue was a separate Windows service called JDE Update 4 B733 Queue or something similar. This service could be stopped and started independently of what was then called JDE Update 4 B733 Network or the "Network" service. This made it easy to restart the queues without bothering the main service. In the 8.9 release however, the queue service was redesigned and turned into a kernel under the main E1 service, greatly complicating the targeted restart of the queues but not making it impossible. Here's how:
Go to the JDEdwards\E812\DDP\log directory and search for files containing the text QUEUE KERNEL. This will give you the queue kernel PID in the file name (i.e. jde_9188.log). You will (should) have only one queue kernel. Go to Windows Task Manager and View/Select Columns and add the PID column. You can kill that PID and the next time a job is submitted the Queue kernel will be restarted.
There are also ways to move jobs from one queue to another but that's a post for another day.
