Re: [wtp-incubator-dev] Increase Java heap size

[Gabriel Petrovay <gabipetrovay@xxxxxxxxx>]

Hi Simon,

Yes, the problem is in XQDT. I have corrected it in the trunk but this will only be available in our next milestone release (sometime end of June).

What you can do until than is to hack a wrapper that calls java again with the needed setting. In order to make it easier for you, I have quickly coded this wrapper for you (see attached). The wrapper takes the following arguments:

JAR_PATH MAIN_CLASS ( SEPARATOR (JAVA_ARGS)* SEPARATOR (ARGS)* )?

All you have to do now is to setup in XQDT this wrapper as an XQuery interpreter and provide the following interpreter arguments for it:

/path/to/mxquery.jar ch.ethz.mxquery.cmdline.MXQuery random_string -Xms32m -Xmx128m random_string -f

Notes:

1. Please avoid whitespaces in the mxquery.jar path!

2. you choose your own "random_string" without whitespaces

All the best,

Gabriel

I am using MXQuery0.6.0.

Everything works fine, problems occur only if I try to parse those big files.

So in my opinion, it is rather an eclipse error than a error of the processor.

Which XQuery processor are you trying to run?

No, I don't want to open them in the XML-Editor, I only want to parse the file with a simple query like:

 

for $y in doc(sw_comp_dev_mod.xml)/MSRSW/CATEGORY

return

data($y)

Are you trying to load these into the XML Editor?  If so they are too large, as the XML Editor needs to load the entire file into memory.

Hi together,

 

I want to parse big XML-Files (32MB) with Xquery.

I always reveive the error: Exception in thread "main" java.lang.OutOfMemoryError: Java heap space

Then I changed -Xms and -Xms in the eclipse.ini but nothing happend, I couldn't fix the problem even if I enter enough memory.

I tried to enter a extreme high value, but after this eclipse didn't start anymore.

 

Do I have other posibilities to change heap size in eclipse?

 

Best regards,

Simon
