MQ JMS Double Get API Calls
Tuning applications is always a good thing. 🙂 Colin Paice has reminded me of the MQ JMS default value for an MQGET buffer size is 4KB in his blog posting here. IBM’s default value of 4KB is far too low to be useful. Having such a low value causes excessive number of MQ JMS Get […]

Updates to MessageSelector Class
In the blog posting, Java MQ Code to Retrieve Messages from a Queue Based on a Filter, I posted code for a Java MessageSelector class. I have updated the setFilter method to catch any invalid values that may be passed to the MessageSelector class on the setFilter call. You can download the source code for […]

Java MQ Code to Retrieve Messages from a Queue Based on a Filter
There is a misconception regarding MQ/JMS message based filtering. Some people think that the IBM MQ queue manager does something special for JMS applications that is not done for plain Java or C/C++/C#/COBOL applications. It is just NOT true. Note: For C/C++/C#/COBOL applications, they can use the SelectionString from MQOD structure to perform message selection. […]

IBM MQ and OpenJDKs
On Monday, Peter Potkay asked a simple question on the MQ List Server: Does IBM support any version of OpenJDK, from any vendor, for use with IBM MQ Clients, specifically the Resource Adapter? Tim McCormick of IBM responded with: The full list of supported JREs are listed in the MQ system requirements here: https://www.ibm.com/support/docview.wss?uid=swg27006467 Specific […]

Excelsior Jet and macOS Mojave
Well, here’s a little oddity that Excelsior Jet users should know about. On Friday, I decided to upgrade my MacBook Pro from High Sierra (v10.13) to Mojave (v10.14). Everything went smoothly. I checked the version level and it said I was running v10.14.2. Note: I have Excelsior Jet 15.3 Professional installed on my MacBook Pro. […]

Its All Fun & Games Until Your Message Is Empty!
