Netrexx Instalation Woes!

[Quique Britto]

Hi all,

I have seen recently many posts regarding instalation of Netrexx, to be honest I never paid much attention because mine was installed several years ago and working since but last weekend one of my machines needed a re-install and now the nightmare has begun.

I have extracted the Netrexx zip, added the tools.jar & NetRexxC.jar to the classpath, but when trying to compile programs (included the hello.nrx) I receive the flwg error msg.

Error occured during initiliazation of VM
too small intial heap for new size specified.

Never have seen this msg before.

Any ideas what this means.

thks to all.

Quique;

I vaguely remember this has been discussed on this list a few weeks ago.
AFAIR you have to remove the option from the java start command in
NetRexxC.cmd.
Look for the thread "NetRexx 2.05 Installation anomalies"

I think this was addressed in one of those threads you mentioned.  That problem was due to a change in recent Java releases which now obey any heap-size option regardless of how ridiculous that request was.  i.e. Even if the requested heap is too small for Java to start it will enforce the request.  As the NetRexxC script was written many years ago when Java initialized with a much smaller heap than NetRexx could use the script asked for a 4M heap.  This size is woefully inadequate for modern JVMs and causes the error you're seeing.

The solution was to edit the NetRexxC script to remove the -ms4M switch from the java command in the script.  For example:

Windows (NetRexxC.bat)
Old version:

java -ms4M %netrexx_java% COM.ibm.netrexx.process.NetRexxC %1 %2 %3 %4 %5 %6 %7 %8 %9

Change to:

java %netrexx_java% COM.ibm.netrexx.process.NetRexxC %1 %2 %3 %4 %5 %6 %7 %8 %9

UNIX (NetRexxC.sh)
Old version:

java -ms4M $NETREXX_JAVA COM.ibm.netrexx.process.NetRexxC $*

Change to:

java $NETREXX_JAVA COM.ibm.netrexx.process.NetRexxC $*



Hope this is what you're experiencing,
Alan.

Ups, missing  "-ms4M" between option and from  :)

thks, fm the command line the compilation completes and programs runs however in jEdit it still tries to compile with the -ms4M, how I can I tell/instruct jEdit to not to use this as the heap msg returns in the iEdit console.

thks again for yr help

Quique,

Please download NetRexxDE 1.0.2c from http://kenai.com/projects/netrexx-misc/downloads/directory/NetRexxDE

This version was quickly released just to fix this very issue.

Rather than recording these solutions in postings, we definitely need to update the downloadable files and the user guide with each solution to prevent reoccurrence of the problem.    Unfortunately the retired technical author I tried to interest in the user guide preferrers his existing interests.

If someone knows of anyone who would be good at either of these tasks, please encourage them into the community.

Regards,

<Connor>

May I also suggest to simply pass *ALL Parameters in zthe Windows BATCH
File to the NetRexx processor,

I.E.  *USE*.

%*
   instead of
%1 %2 %3 %4 ... %9

!!! :-)
