An application server cannot shut down if a WebSphere MQ link sender channel is waiting for its disconnect interval to expire - Middleware News

If a WebSphere MQ link sender channel does not have any messages to deliver, it waits for its specified disconnect interval before timing out. If the application server is shut down while a WebSphere MQ link sender channel is in a wait state, the application server waits for the WebSphere MQ link sender channel to time out before shutting down. A long disconnect interval might delay the server shutdown.
If the application server shutdown is delayed by a WebSphere MQ link sender channel in a wait state, you have two options:
  • Attempt to put a message onto the transmission item stream for the WebSphere MQ link sender channel. Note that this might not take the channel out of its wait state if the application server shutdown is already in progress
  • Force the termination of the application server process.
To reduce possible delays during application server shutdown, you can specify a smaller value for the disconnect interval. Note that a discount interval of 0 indicates an indefinite wait. For more information about setting the disconnect interval for a WebSphere MQ link sender channel, see Adding or modifying a WebSphere MQ link sender channel.

Adding SSL certificates to a mixed z/OS and Unix queue manager environment - Middleware News

Adding SSL certificates to a mixed z/OS and Unix queue manager environment - Middleware News 1. Security Considerations IBM advises customers who are using SSL, that the most secure way to do this is to use recognized Certification Authorities to sign their certificates. Ensuring secure transfer of information is the main purpose of SSL. This integrity must be properly observed when setting up SSL. You should always be certain who has signed each of your SSL certificates, who has had and who continues to have access to them. The first secure way to generate certificates is to generate a certificate request, on each system or machine that uses SSL. This request has to be signed by an external Certification Authority before it can be used. Getting certificate requests signed by a CA is secure, because during the signing process at no point do any files contain the certificate's Private Keys. This principle is vital to SSL security. Signing certificates in this way is covered...
