set the cipher suite blank to remove the SSL config from the channel.
Have fun ![](images/smiles/innocent.gif) _________________ MQ & Broker admin |

As already noted, blanking out the SSLCIPH field - at both ends - is the controlling attribute for SSL on a channel.

SSLCAUTH(OPTIONAL) only says that SSL connections that don't send a certificate are still allowed to connect to this channel - i.e. anonymous ones. It is still an SSL channel until the cipher spec (SSLCIPH) is removed.

Sorry to raise an old post.
After clearing the cipherspec from both ends of a sender/receiver channel pair on z/os qm (v9.0) - I can't restart the channel.
Is there a need to refresh ssl or something like that on z/OS?
CSQX558E is the error I get _________________ Well, I don't think there is any question about it. It can only be attributable to human error. This sort of thing has cropped up before, and it has always been due to human error. |

Make sure the channel is stopped and not idle (on both ends). Then verify address and port are reachable and restart the channel, starting with the receiver, then the sender.

Thanks, not often that I would think to start the receiver channel by hand. _________________ Well, I don't think there is any question about it. It can only be attributable to human error. This sort of thing has cropped up before, and it has always been due to human error. |

You need to stop the channel to make it take the change. Including the receiver channel. If you just leave it inactive you are not implementing the change... ![](images/smiles/innocent.gif) _________________ MQ & Broker admin |

Error message CSQX558E is just telling you that the receiver end is (most likely) stopped. Check the error messages at the receiver end to see exactly the reason for the problem. This is nothing to do with SSL, probably just you stopped the receiver and thus put it into STATUS(STOPPED).
Remember that you can use STOP CHANNEL(chl-name) STATUS(INACTIVE) MODE(FORCE) to immediately stop a receiver channel, but leave it capable to being restarted by a sender again next time it needs to be.
There is no need to make sure the channel is STATUS(STOPPED) at both ends before restarting them again. Just make sure the channel is not running - STATUS(INACTIVE) is not running, and then start it up again.
If you have a receiver channel in STATUS(STOPPED) you can re-enable it again with either of the following commands issued against the RECEIVER channel:-
START CHANNEL(chlname)
or
STOP CHANNEL(chlname) STATUS(INACTIVE)

To remove SSL (Secure Sockets Layer) from a channel, you would typically follow these steps:
Access Channel Settings: Log in to your server or application where the SSL is configured for the channel. Navigate to the settings or configuration menu for the specific channel you want to modify.
Locate SSL Configuration: Look for the section or option related to SSL configuration for the channel. This could be labeled as "SSL Settings," "Security Settings," or something similar, depending on the platform you're using.
Disable SSL: Within the SSL configuration settings, there should be an option to disable or turn off SSL for the channel. This may be represented by a checkbox, toggle switch, or dropdown menu.
Save Changes: Once you've disabled SSL for the channel, be sure to save the changes. This usually involves clicking a "Save" or "Apply" button within the settings interface.
Restart Channel (if necessary): Depending on the application or server configuration, you may need to restart the channel or the entire application for the changes to take effect. This step ensures that the channel operates without SSL after it's been disabled.
Test the Channel: After disabling SSL, it's essential to test the channel to ensure that it's functioning correctly without SSL encryption. You can do this by attempting to access the channel through a web browser or application to verify that it's accessible and working as expected.
By following these steps, you can successfully remove SSL from a channel, thereby allowing communication to occur without encryption. However, be sure to consider the security implications of disabling SSL, as it may expose sensitive data to potential risks if transmitted over unencrypted channels. |

Hi Liand1,
That's a thoughtful and detailed reply, but this process really only applies to a MQ Client application that has built-in capability to configure the CLNTCONN channel connection (rather than relying on mqclient.ini, CCDT, environment variables etc.).
If SSL/TLS is being used on MQ sender/receiver etc. channels, the process will be to use the MQ administration tools (runmqsc, ISPF, MO71 etc) to reconfigure and restart the channels, not what you stated.
Restarting the channel is necessary, as any running channel has its own copy of the channel configuration, and runs with those settings.
If the channel is not running (ie. its inactive) at the time of the change, the changes will take effect next time the channel starts. _________________ Glenn |

So did I, but it seemed to be quite factual, whereas other AI generated posts by new users were basically regurgitated rubbish.
