My name is Roger Lacroix and I am a die hard programmer. I have been programming since the 80s. My favorite programming languages are Java, C and Rexx. I have worked in the Airline, Retail but I have spent most of my time doing middleware work in the financial services industry. In 1994, I was introduced to IBM MQ (aka WebSphere MQ & MQSeries) and I thought it was the next best thing since man created fire. This blog will be about IBM MQ, Java, C, Rexx and any other interesting items that I can think of. I hope you enjoy it.

Did I miss the miniaturization memo? After waiting for months, last month I was finally able to order a Raspberry Pi for $35.00 USD. Now Hardkernel (Korean company) is offering a premium board called ODROID-X for $129.00 USD. Yes, it is more money but you get a quad-core ARM CPU and 4 times the amount […]

Robert X. Cringely has an interesting perspective of the PC era: http://www.cringely.com/2012/06/30/life-personal-computer/ If you extrapolate Robert’s thoughts to other computing environments then you would say: – The mainframe is dead – long gone buried. Oh wait, it lives and is doing very well. – The super-computer is dead. Well, it almost died but with Linux […]

amqrmppa on AIX Leaks Memory When using a Security Exit

July 4, 2012 Roger Lacroix
s

If you use a security exit with WMQ v7 on AIX, the amqrmppa process has a bug that causes it to leak memory. When the security exit accepts/allows a connection, about 0.24KB of memory per connection is leaked. When the security exit rejects a connection, about 0.61KB of memory per connection is leaked. IBM has […]
