Re: [Condor-users] JAVA_MAXHEAP_ARGUMENT parameter causing error (Windows)

Klaus,
I would be interested in hearing from the condor listsvr on this topic as
well. I am currently using 7.5.6, but I have not been able to configure
java correctly since version 7.2.x. I have posted questions about this and
there has been many questions about setting up java for windows, but none
of these have worked.
The solution I have used is to copy the java installation to an NTFS and
then I can run jobs requiring java using this. Obviously, this is less
than ideal but because I could not figure out the configuration it has
allowed me to run jobs via java.
I cannot find my notes on this, but I have also read on java blogs that
the location for where java.exe is installed has changed with different
versions. For example, I think some apps will copy the java.exe to the
system32 folder because I do not think the java installation does this any
longer. Therefore, I have had a difficult time trying to automate the
configuration when specifying the JAVA config macro.

[Condor-users] JAVA_MAXHEAP_ARGUMENT parameter causing error (Windows)
Sent by:

I am testing Condor 7.5.6 on Windows machine and am getting the folloqing
error message:
03/31/11 09:56:30 Locale: English_United States.1252
03/31/11 09:56:30 JavaDetect: failure status 1 when executing
C:\WINDOWS\SysWOW64\JAVA.exe -Xmx -classpath
C:/condor/bin;C:/condor/bin/scimark2lib.jar;. CondorJavaInfo old 2
JAVA_MAXHEAP_ARGUMENT is set to -Xmx in accordance with the definition of
it on the documentation:
JAVA_MAXHEAP_ARGUMENT
An incomplete command line argument to the Java interpreter (the Java
Virtual Machine) to specify the switch name for the Maxheap Argument.
Condor uses it to construct the maximum heap size for the Java Virtual
Machine. For example, the value for the Sun JVM is -Xmx.
On Linux machines it works accordingly.
When I set to -Xmx1024M, for exemple, the error doe not occur.
Seams to be a problem of interpreting that parameter in Windows version of
Condor.
Am I correct?
Thanks,
Klaus
