Rather depends on what sort of HA clustering is being used.
Failover to make it inactive first might be preferable. |

Yes, DNS was my first suggestion when they asked us to code 6 host names in the connection name field of a z/OS channel (2 sites x 3 hosts).
However we really need not just one DNS for each IP - bu ... |

| It would be useful to have this option. I expect many older QMs (especially mainframes) do not have connauth enabled. The problem being there is no way to exempt certain userids or channels from it.

Yes, but we have a Z/OS QM that needs to connect to the Linux RDQM.
The z/OS sender channel DOES have a 48 character limitation.
The generated CONNAME is always in the dotted decimal (IPv4) or ... |

RDQM means there are three Linux hosts where the RD QM might be running (on one of them only).
Issue 1
To code three hosts addresses in a z/OS sender channel is impossible in the 48 characters a ... |

Yes, a bit simple to bypass queue security when you can define a QALIAS !!!
We do keep trying to tell our security people that it is pointless to try to restrict MQ administrators. |

Thanks. I would imagine that MQ client auto-reconnect would help with disconnects.
We have many MQ client applications and the general preference is not to have QMs sited close to each application ... |

So assuming there are central in-house legacy systems with MQ Q ... |

Thanks
I am looking for published figures on the ciphers relative performance.
Actually we might use TLS 1.3 - TLS_AES_256_GCM_SHA384. |

RESLEVEL is a RACF check made by MQ.
If you don't have a specific RACF profile to match, it will pick up a access level from whatever profile happens to match, such as QM.**
