MQSeries 2045: MQRC_OPTION_NOT_VALID_FOR_TYPE

8. July, 2008

While doing some work with MQSeries, I got an error “MQJE001: Completion Code 2, Reason 2045” in MQQueueManager.accessQueue() which translates to “MQRC_OPTION_NOT_VALID_FOR_TYPE”. Hm. Hey, IBM, how about adding real error messages to your products instead of having people look up odd codes in tables?

Anyway, the error means that I’m trying to open a queue for output which doesn’t support this. For example, remote queues can be opened with the option MQC.MQOO_OUTPUT but not with MQOO_BROWSE or MQOO_INPUT_AS_Q_DEF. Other queues don’t allow to read from them, i.e. you have to get rid of MQC.MQOO_INPUT_AS_Q_DEF in the openOptions.

See this page for all possible combinations: MQOPEN – Open object


TurboGears 2.0 Is On Track

8. July, 2008

There are three things which hooked me to TurboGears:

  1. Every day stuff is simple, complex stuff is possible
  2. Automatic reload after code change (no need to restart)
  3. It’s in Python

What I didn’t like is that TG 2.0 has been so quiet for so long. I’m on the Planet Turbogears RSS feed and I wasn’t sure whether 2.0 was alive or dead or whatever.

Well, it seems to be more alive than I expected and hopefully, we’ll see a 2.0 soon. In “Doing the right thing should be easy” by Mark Ramm, you can find more details.


Starting Your Own OSS Project

8. July, 2008

If you’re planning to roll your own little OSS toy project, you should read the article “Party of one: Surviving the solo open source project” by Kirill Grouchnikov. Very good points on what to do and what to avoid and why.


Genes in Wikipedia

8. July, 2008

So if you ever wanted to know how that stuff works that you’re made of, scientists have started to put their knowledge about genes on Wikipedia. Beware, though, it’s heavy stuff.

It’s interesting to see how you can use an automated process to merge complex information from one system (the scientist’s databases) into another. Now, I’m waiting for the “translate this goo into language xyz” bot 🙂
