Setting Java memory

[Gary Murphy]

I'm having some trouble trying to increase my Java -Xmx settings.

From the topquadrant FAQ ...

Can I increase the amount of memory for Composer?

Increasing the amount of memory available to Composer involves setting the -Xmx value for the maximum Java heap size. The setting is packaged in the .ini file with the command line parameters for starting Composer.

There is a caution that in Windows you must edit the .ini.orig file, and no explicit instructions for Linux installations, however I edited BOTH

/opt/topbraid-5.3.1/TopBraid Composer.ini:-Xmx4096M
/opt/topbraid-5.3.1/TopBraid Composer.ini.orig:-Xmx4096M

and yet when I run, the process command line still says -Xmx2048 ...

16940 ?        Sl     1:18 /opt/topbraid//./jre/bin/java -Dorg.eclipse.jetty.server.Request.maxFormKeys=2000 -Xmx2048M -Xms640M -XX:SurvivorRatio=16 -XX:NewRatio=3 -jar /opt/topbraid//plugins/org.eclipse.equinox.launcher_1.3.201.v20161025-1711.jar -os linux -ws gtk -arch x86_64 -showsplash /opt/topbraid//plugins/org.topbraidcomposer.maestro_5.3.0.v20170419-1607R.jar/splash.bmp -launcher /opt/topbraid/TopBraid Composer -name TopBraid Composer --launcher.library /opt/topbraid//plugins/org.eclipse.equinox.launcher.gtk.linux.x86_64_1.1.401.v20161122-1740/eclipse_1618.so -startup /opt/topbraid//plugins/org.eclipse.equinox.launcher_1.3.201.v20161025-1711.jar --launcher.overrideVmargs -exitdata 158002 -vm /opt/topbraid//./jre/bin/java -vmargs -Dorg.eclipse.jetty.server.Request.maxFormKeys=2000 -Xmx2048M -Xms640M -XX:SurvivorRatio=16 -XX:NewRatio=3 -jar /opt/topbraid//plugins/org.eclipse.equinox.launcher_1.3.201.v20161025-1711.jar

And in the Composer error log I see

!ENTRY org.topbraidcomposer.core 2 0 2017-07-21 10:56:00.924
!MESSAGE P2 modified ini file, switching it back

What am I missing here?

Gary,

This might just show my ignorance of Linux, but it looks like you are editing the ini files in /opt/topbraid-5.3.1 but the app is launched from /opt/topbraid. Are these two different copies?

No conflict, the launch is by way of a symbolic link :)

/opt$ ls -l topbraid
lrwxrwxrwx 1 root root 14 Jun  6 14:02 topbraid -> topbraid-5.3.1

I do this when I upgrade so that my dev environment is always looking at the 'current' version. Just to be sure, though, I had already deleted the prior installations ;)
