How do I determine a SOCKETCLOSE value for Outbound Connection Pooling in CICS?
Although the manuals make a great effort in explaining what is needed to configure Outbound Connection Pooling, you may still need some help with tuning a compatible SOCKETCLOSE value that will work within your system. Hopefully, the information below will assist you in making this an easy task. Start by specifying a SOCKETCLOSE value of one minute 000100 (hhmmss) or a value of your choosing.

WebSphere MQ for z/OS Version 8: New Toys In the Box!
It's the moment you've all been waiting for (I know I have). Version 8 of WebSphere MQ has been announced and will soon officially become available for the z/OS platform (General Availability date 13 June for z/OS, eGA of 23 May for multiplatforms). When I was reviewing early release materials for documentation on the product I was happy about many of the changes that had been implemented by Development.
