May 06 11:14:12:976 [/UIM_ServiceNow, messagegtw] Not able to callback for hubpost_bulk. Reason is: java.lang.reflect.InvocationTargetException
Environment
Release : 20.1
Component : UIM - MESSAGEGTW
Cause
- messagegtw data_engine configuration value
Resolution
On the machine where messagegtw was running, select the controller probe and press Ctrl-P to open the probe utility.
Run the nametoip callback and entered what was configured in the messagegtw for the data_engine address on the Primary hub.
/XXX_UIM_PRD/XXX_Prd_Pri_WT1/aa1snnnnnn55/data_engine
but it failed.
Checked the data_engine address on the Primary but the case for the hostname was different (UPPERCASE).
/XXX_UIM_PRD/XXX_Prd_Pri_WT1/AA1SNNNNNN55/data_engine
Therefore, changed the data_engine address to that value for the nametoip callback value in the Probe utility and it then succeeded (OK).
Updated the data_engine address in the messagegtw and restarted it and the connection was successful to the data_engine on the Primary.
Issue resolved.
