Hi Alex,

I did some testing too. I have sun-jdk6 installed.
Here’s the output I got once when starting glassfish:

sudo /etc/init.d/glassfish start
Password:
starting glassfish from /opt/glassfish/bin
Starting Domain domain1, please wait.
Log redirected to /opt/glassfish/domains/domain1/logs/server.log.
Redirecting output to /opt/glassfish/domains/domain1/logs/server.log
Error occurred during initialization of VM
Could not reserve enough space for object heap
Could not create the Java virtual machine.

I had to stop the mysqld for launch and then glassfish comes up as usual. But don’t bother. I expected running into trouble like this when installing glassfish on such a lowend configuration. You simply can’t put a liter of beer into a pint.

I did a bit of testing using a VirtualBox 512MB-constrained virtual machine. I don’t seem to run into your memory problem when doing :
% sudo apt-get install glassfishv2

Note you need to have Sun JDK installed (apt-get install sun-java6-jdk) first as neither OpenJDK (for the moment) not gcj will work (the initial domain1 creation will fail).

I haven’t installed GlassFish on the latest Ubuntu so I’ll try that in a 512Mb-constrained VM. What about when starting GlassFish (the PermGen setting), does domains/domain1/log/server.log contain anything when using the default PermGen setting? Alernatively you can try startting using:

sudo asadmin start-domain domain1 –verbose

to get errors inline.

Hi Alex!

I’m not a hosting pro, too
I configured this virtual server to run Ubuntu Server Edition.
My server came with preconfigured openSUSE 10.3 and Plesk 8.4, but the first thing I did after activating, was switching it to ubuntu.

The out of memory exception was thrown when the apt package manager wanted to start it’s installation routines. I have installed glassfish through apt on several other machines an everything went fine.

And yes… 512mb is all I got I think strato regulates it through their virtual server settings. But for the moment is sufficient. The site I run there is low on traffic. And should it rise then getting a bigger machine isn’t the problem.

I searched the machine for an error-log of the failed installation attempt, but as far as I have learned there is no log file for apt installations.

Hope this helps,
Lars

Hi. Thanks for the entry. I have a couple of questions (forgive my ignorance of maybe some basic hosting constraints) :

- which linux distro are you using (Debian, Ubuntu)?
- where does apt-get fetch bits from? apt-get shouldn’t invoke the installer.
- is the outofmemory error related to GlassFish v2 or specifically to ur2?
- do you have the exact error message when trying to start the instance with the default MaxPermSize?
- is 512MB really all you get? How is this enforced at the OS level?

GlassFish v3 and its modular/lightweight architecture should be really nice for hosting companies.

thanks!
