The MIExecution Service,on each GE Digital APM Server serves RBI, Inspection and Thickness Monitoring module queues. This service is configured to use a single shared ActiveMQ queue service across APM. Available queue configuration options include retries and concurrency limit.

1. On the GE Digital APM Server, access the folder that contains the MIExecution Service files.
   Note: If you have installed GE Digital APM in the default location, you can locate the folder in C:\Program Files\Meridium\ApplicationServer\mi-execution
2. Access the appsettings.json file in an application that can be used to modify JSON files (for example, Notepad++).
3. In the file, locate the following text:

   "Queue_Config": {
   	    "Queues": [
   	      {
   	        "Name": "MI_TM_Queue", 
   	        "ConcurrencyLimit": 100,
   	        "Retries": 5,
                  "LimitPerTenantRequired": true
   	      }
   	    ]
             }

   Note: ConcurrencyLimit indicates the maximum number of messages that will be consumed concurrently. Retries indicates the number of times it retries to send the messages to ActiveMQ if it fails. LimitPerTenantRequired indicates whether Maximum Concurrency limit per Tenant is specified in scheduler service for the queue.
4. Update the key values as desired.
5. Save and close the file.
   The updated settings will be applied when the MIExecution Service is stopped and restarted.
