Giving ElectroServer more memory

So after last time, I thought I’d given ElectroServer more memory, but it turns out I hadn’t. I’m not exactly sure why, but I suspect it’s something about how Media Temple is set up.

So rather than call the main ElectroServer app (which is just a shell script), I’m opening the ElectroServer jar file, and that way I can tell java how much memory to use (and other options) as parameters.

I’m pretty sure Java is installed somewhere on Media Temple (you need to install the dev tools) but I couldn’t find it anywhere! And if I just typed java it couldn’t find it. I even ran a find command, but it was nowhere! But then I realised that the Java runtime is packaged with ElectroServer in the jre folder!

So with a bit of fiddling I worked out that I could start ElectroServer with more memory by running the jar file, but I had to do it while in the server subfolder within the ES install.

../jre/bin/java -Xmx128M -jar lib/ElectroServer4-bootstrap.jar -mode StandAlone -config config/ES4Configuration.xml

where 128M is the amount of RAM made available.

[UPDATE]

There is a better way! Thanks to Paul Hayes (a colleague at Plug-in Media, see comments below) I have now realised that ElectroServer’s main app is nothing more than a shell script that you can edit. Furthermore there is a line you can uncomment right at the top to change the Java parameters :

# Uncomment the following line to add additional VM parameters
# INSTALL4J_ADD_VM_PARAMS=

Change this to :

# Uncomment the following line to add additional VM parameters
INSTALL4J_ADD_VM_PARAMS="-Xmx512m"

Where 512 is the amount of RAM in Mb you want ElectroServer to use.
