MQSeries.net :: View topic - Unable to connect Remote Integration Node from ACE toolkit

ghoshly

We had ACE Integration Node with version 12.0.8.0 in AIX 7.2 and recently we installed 12.0.12.7 in parallel in the same server.

Underlying MQ version is also upgraded to 9.3.0.25 from 9.3.0.4 in place.

I have upgraded existing Integration Nodes via mqsistop -> mqsibackupbroker -> mqsiextractcomponents (with delete existing node) -> mqsistart commands.

I am able to connect to the newly created Integration Nodes via WebUI using our local credentials, able to execute basic commands like mqsilist, mqsireload, mqsideploy etc. however with ACE 12.0.12.7 Toolkit, I am unable to connect to those remote Integration Nodes. I tried to restart toolkit with -clean or run toolkit in Administrator mode from windows 10 laptop.

I have checked MQServer environment variable (already existing), changed network connection to 'Direct' as per link -

What I am missing? I tried to check workspace metadata log but nothing is updated there and I am not finding error code or error details in System event viewer as well. Only error message via pop up window says -

An error occurred while attempting to connect to 'sdxbf-m23n6:4415'.
