HI ,
I am trying to change my SUITEB value of the qmgr from 'none' to '128-bit' .
this is advised to do as per security baselines for me.
Do we need to do any refresh security for the changes to affect.
I tried checking google it only says to restart Mqxr service after the modification .we dont have this service.
Can someone guide me if the refresh will work or restart of the qmgr is needed. |

https://www.ibm.com/docs/en/ibm-mq/9.3?topic=mq-configuring-suite-b
Implies qmgr restart only if MQXR (Telemetry) or AMQP (MQ Light client / open source) are being used. It is just an internal check on cipher spec compliance to particular EC signature algorithms. If an out of scope spec is attempted to be used, the MQ channel or connection will fail. _________________ Glenn |

Thanks Glenn for the reply ,we are not using telemetry or amqp service.
i just updated the suiteb value to 128 bit and done refresh security.
Just wondering if refresh security alone will be fine without any qmgr restart.
Dont see any issue with the channels till now.will have to wait and see. |

Glenn's reply was telling you that the IBM docs show that you only needed to do a restart IF and ONLY IF you are using MQXR or AMQP. Since you are not, you don't need to do a queue manager refresh.

It is worth knowing that the REFRESH SECURITY TYPE(SSL) command is doing the same thing that would happen on a queue manager restart when it comes to updating the SSL/TLS environment when something in that environment has changed. If you have done a refresh you shouldn't need to do a restart and vice versa.

Do any channel definitions have SSLCIPH set to a non-blank value? Have you reviewed that the values are all SUITEB 128 bit compliant? _________________ Glenn |
