IBM MQ 8.0, How to specify a username and password for amqsget as command line parameters

Question

I get an error when upgrading to IBM MQ 8.0 from 7.5 reasons -

MQ 8.0 introduces a new feature that requires MQ administrators to use remote access to provide a user ID and password. If the user ID and password are not specified or the password is incorrect

Error: 2035 Code: 2 The queue manager is configured to require a user ID and password, but none of them has been sent.

The problem is described better in this link . There are three scenarios that are talked about. My solution will fall into scenario A) MQ Samples: provide the user and password for the MQ client application

I am trying to read from MQ using a program. Is there a way to pass the username and password as part of the command line options, and not enter it when prompted. Since this exe is called by my program.

$ amqsputc qName qMgr 

Answer 1

To accomplish this, IBM provides a client-side security exit called mqccred . Full documentation is provided here, but in general it requires the following:

• Specify the output in the CCDT file.
• Configure the output by putting the ID and password in the ini file
• Run the runmqccred command against the ini file to trick passwords.
• Make sure the ini file is set so that reading in world and group mode is disabled.

Please note that Java / JMS programs can be easily changed, and the output is mainly for programs that use their own C API or that are compiled on top of this.

If your client cannot (yet) specify a username / password, you can disable the username / password requirement in the MQ 8.0 queue manager:

• Launch MQ Explorer

• Go to Queue Managers → <your_queue_manager> → Authentication Information

• Click " Show system objects " in the upper right corner

4. SYSTEM.DEFAULT.AUTHINFO.IDPWOS → User ID + Password → Check Client Connections → Select More

5. Right click on your queue manager and rarr; Security → Update authorization service ...

Answer 3

Have you tried to provide a password using heredoc, for example?

 amqsputc qName qMgr <<< "passwd" 

Send string to stdin

Answer 4

MQ Samples have been updated to indicate a user ID, and, if asked, will prompt for a password: MQ Bitesize Blogging

Some use the new optional command line parameter [-u User], others check for the presence of the MQSAMP_USER_ID environment variable.
