Hi,
I'm putting together a fairly large piece of mapping code. The code is generated by an external tool we've developed in-house, and then pasted into a PROCEDURE in the ESQL-file in a sub-flow. Problem is, the workbench takes ages to process this (we're talking 10-15 minutes), and also when any changes are done to the chunk of code. This renders the whole approach virtually useless.
To give a feeling for the size of code, we're talking about 1500 lines of code, of which a fair amount are lines with a IF THEN <assignment> END IF; construct on each line.
I'm running on a machine with 1 Gb memory, Intel III Mobile 1000 Mhz, Win2000.
Any hints, suggestions etc greatly appreciated!

The first thing is to use references instead of full paths to variables.
If you are working with, say, child nodes of OutputRoot.MRM.MessageBody.ComplexType1.ComplexType2, then creating a reference to that, and then setting myRef.Field1, myRef.Field2, etc will speed up your execution.

Edited:
The above is still true, and a good idea. But it's not what you're asking about.
Try adding -XmxNNNm (like -Xmx512M) to the -vmargs options to mqsistudio.exe in your shortcut.

Hi,
Thanks. I'm trying to find the syntax for the mqsistudio.exe somewhere, but can't. So, couple of questions:
- What does a complete commandline look like?
- What is the default setting for this?
Thanks a bunch in advance!

Probably, the place these are listed is in the Help. Or on eclipse.org, since mqsistudio is basically an eclipse runtime. Although the arguments I'm mentioning are JVM arguments, not eclipse arguments.

As far as I know, the default command line in the shortcuts in your program menu is "<path to WBIMB root>/eclipse/mqsistudio". And there probably isn't a default value for the vmargs maximum JVM heap size.
And I should have had you put something in the MINIMUM JVM heap size vmarg, which is -Xms not -Xmx. Sorry!
