refresh security reconnect

REFRESH SECURITY(*) TYPE(SSL) lacks the option equivalent to endmqm -r
to indicate that clients should start a reconnect sequence when security is refreshed.
In other words, reconnectable MQ clients do not try to reconnect when "refresh security(*) type(ssl)" is executed.
Could you add such an option?

    I have interest in seeing MESNS-I-155 integrated into MQ. The ability to refresh SSL without affecting many channels would greatly help environments that need to be highly available. This can be the case where external partners need an updated CA chain added to the MQ Keystore to continue encrypting their channels.

    It would be interesting if an expiry mechanism could be integrated into the processes that contain static copies of the MQ Keystore. This could provide a solution where pooled connection processes like amqrmppa are marked "old" during a refresh, and new Receiver channel connections are directed to a new amqrmppa process with a new static copy of the MQ Keystore.

    This is still something we'd like to do, but it's likely to be a different solution than the 9.2.5 client-side implementation. The need for I-96 might diminish if this is done, but it still has some independent validity so we didn't want to merge the two records completely.

    Hi Mark,

    The 9.2.5 CD release saw a feature for MQ clients allowing for TLS keystore updates to be picked up by any new TLS connections made by the client. Could this functionality be ported over to the server side as well? That would negate the need for this idea of the -r, because it eliminates the connections dropping out entirely, but at the expense of additional system resources being used (therefore meaning customers will need to weigh up the performance considerations vs the security concerns associated with longer lived certificates).

    Please ensure any solution does not require changes to the MQ client applications code (such as a new option on MQCONNX) as this is hard or impossible to achieve, especially with vendor supplied packages.

    Unmerged from 217 as the solutions to each have now diverged. But we still hope to deliver a solution for this independently of 217 in a future version of MQ.

    This has been merged with MESNS-I-217 (MQCONNX not able to use alternative SCO) as our expectation is that our ideas on how 217 could be implemented conveniently go a long way to meeting the need for this one as it would actually remove in most cases, the need to run the REFRESH command.


Introduce Graceful restart option for REFRESH SECURITY TYPE(SSL)

When renewing a certificate, it is necessary to refresh the ssl connecitons with the REFRESH SECURITY TYPE(SSL) command withing the queue manager. This has the affect of ending any active channels using SSL/TLS and them allowing them to restart. T...
