Hi everybody, working with IBM RPA and MQ Series we have incurred in this issue (see below). Anyone could help us?

thanks

Regards

**************************

The issue is related to IBM MQ. We had to choose IBM MQ over Microsoft Message Queuing (MSMQ) because the agents need to be installed on different VLANs (according to the documentation, MSMQ limits server and client to the same VLAN). 

During the IBM RPA installation, we are asked for the credentials and connection details for IBM MQ:

Hostname: B80-C-PMAG01

Port: 1414

Queue Manager: RPASYSTEM

Channel: RPA

User: Magadmin (local admin) Password: *** 

However, after entering this information, we receive the following error: MQRC_NOT_AUTHORIZED and the installation does not allow us to proceed.

Tests performed on IBM MQ:

 Running the command runmqsc RPASYSTEM from CMD (starting mqsc RPASYSTEM with the current user, i.e., Magadmin), the manager starts successfully:

 Starting MQSC for queue manager RPASYSTEM

Running the command runmqsc -u 'Magadmin' RPASYSTEM from CMD (starting mqsc RPASYSTEM with the user Magadmin explicitly specified), we receive an error:

 AMQ8135E: Not authorized.

 

Additional Environment Details: 

The IBM MQ service is set to "Log on as System Account".

The user "Magadmin" is a member of the Windows mqm group.

 The user "Magadmin" is a local administrator.

 This is the same account used to install IBM MQ and is currently being used to run the IBM RPA 30.0.0 FP2 installer.
