error 'Jave heap space'

[news]

Hi,

I'm running a multiple histograms graph with a panel sub command  and
get an error 'Jave heap space'. The graph isn't created.
The data set that is to be visualised is a large survey (n > 100,000).

This is the syntax I use:
GRAPH
   /HISTOGRAM(NORMAL)=opendim
   /PANEL COLVAR=attend COLOP=CROSS ROWVAR=prayr ROWOP=CROSS .

I found the help page
http://www-01.ibm.com/support/docview.wss?uid=swg21480232 which says I
should increase the Xmx64M parameter in the jvmcfg.ini file .

But to which level ? How can I calculate it ?

Reducing the size of the data set to a quarter of the initial sample
size produced the same error message.

I use SPSS 15.
TIA

    Resolving the problem

This is how to find the version of the JRE that SPSS uses:

C:\PROGRA~1\SPSS15\JRE\bin>java -version
java version "1.5.0_06"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_06-b05)
Java HotSpot(TM) Client VM (build 1.5.0_06-b05, mixed mode)


Look at jvmcfg.ini in the SPSS directory. There are Java heap parameters
in this file, i.e.

[Startup Parameters]
; Set maximum Java heap size to 64 megabytes
-Xmx64M
-XX:-UsePerfData
-Xrs

Increase the -Xmx parameter in the jvmcfg.ini file

Newer version of Statistics are more parsimonious in how they assemble the histogram data, but in your case, you will need to just experiment with the jvm size or sample the data.  Try doubling it and then doubling again.  The limit on the heap size is present in order to ensure that the jvm does not take so much memory that other programs running at the same time are starved for memory.  Therefore, the ultimate practical limit will depend on how much memory your system can use.
