Marmotta starting problem
Hello,
I'm having a problem with marmotta. After installing the standalone version
of marmotta, I tried to run it but nothing happened. There was a splashing
screen of command prompt and that's it. I also tried to run it with
administrator but it didn't work.
I have encountered the same problem with linked media framework. After
installing LMF the 1st time, I was able to start it. However, after
restarting my computer, I could not run it again.

Does not matter how much physical memory your machine has, by default
the JVM will allocate only 4MB for heap, I think, which wouldn't be
enough for running Marmotta. So it's important to properly configure
those aspects, as it's described at:
http://marmotta.incubator.apache.org/installation.html#war
You can find some more information at:
http://docs.oracle.com/cd/E15523_01/web.1111/e13814/jvm_tuning.htm

Hi,
My marmotta version is 3.0.0. OS: Windows 7 64-bit. Java: 1.7.0_17.
I was able to reproduce the error after deleting the JAVA_OPTS variable.
When I run this command *catalina.bat run, *I receive the following error
message:
Error occurred during initialization of VM
Could not reserve enough space for object heap
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
At that moment, the task manager showed that I had 4GB RAM available.
Best,
Thang

That's try: the installer should care about those details. So we might
have an issue on setting such variables from the installer. Can you
please provide us more details about the environment? Marmotta version,
Java version, operative system and so on.

Well, depending how you set it, there is a way to revert it. That would
help to know the memory setting Tomcat is getting by default from the
installer.

You should be able, yes. Although that could be related with MARMOTTA-253?

If not, please report the details to the issue tracker.

Re: Marmotta starting problem
Posted by Thang Chi Duong <sv...@gmail.com>.
Hi,
I was able to start marmotta after setting the JAVA_OPTS environment
variable. SInce I installed Marmotta using the standalone installer, I
thought that I didn't need to set the variable.
After I set the variable, I cannot reproduce the error again. Therefore, I
can not provide you more information. Sorry about that.
Moreover, I found a minor bug: the context/graph can not be deleted. Is it
intentional ?
Best regards,
Thang

How have you installed Marmotta? From the installer or have you deployed
in your current installation of Tomcat? The issue to give you a proper
solution is you still did not provide more details about the problem
(java.lang.OutOfMemoryError exceptions or whatever).
Anyway, first you would have to check your JVM is 64bits, and then your
memory settings used by Tomcat. If you followed the documentation:
http://marmotta.incubator.apache.org/installation.html#war
You would have something like:
export JAVA_OPTS="-Djava.net.preferIPv4Stack=true -Xmx1024m
-XX:PermSize=128m -XX:MaxPermSize=256m -XX:+UseConcMarkSweepGC
-XX:+CMSClassUnloadingEnabled -XX:+UseConcMarkSweepGC
-XX:+HeapDumpOnOutOfMemoryError"
Notice 1GB is the recommend memory, although with less should run fine too.

Dear Thang Chi Duong,
sorry to hear that :(
If you could provide us more details about the environment where you are
trying to run Marmotta (java version, javaee container, etc), plus some
information from the logs (both marmotta-main.log and catalina.out in
case you are using Tomcat), we could try to find the source of the issue.
Best,
Sergio
