HI!

Now I've just download and I'm unable to start the free version of BigMemory MAX (4.0) If I set the offheap size in tc-config.xml (even lower than set in the -XX:MaxDirectMemorySize) I get the following error:

2013-03-06 18:18:47,143 INFO - Available Max Runtime Memory: 989MB
2013-03-06 18:18:47,403 ERROR - The JVM argument -XX:MaxDirectMemorySize(64m) ca
nnot be less than TC minimum Direct memory requirement: 171m

Although I've put -XX:MaxDirectMemorySize in start-tc-server.bat:

:START_TCSERVER
%JAVA_COMMAND% -XX:MaxDirectMemorySize=3072m %JAVA_OPTS% -cp %CLASSPATH% com.tc.server.TCServerMain %*

tc-config.xml

<offheap>


<enabled>true</enabled>


<maxDataSize>2g</maxDataSize>
</offheap>

If I disable offheap (and restartibility) then I also get an error:

I'm testing it on a 32-bit Windows7 (virtual machine), with java version "1.7.0_11"

The second message is not an exception, it is printed each time the server starts normally.

Are you sure you're not overriding the direct memory size from some other command?

Yes, you're right, thnx..I've just issued an echo command for JAVA_COMMAND, and got the output:

c:\java\jdk7u11\bin\java -server -XX:MaxDirectMemorySize=2147483647

so I could one step further by setting offheap size 2005m

<offheap>

<enabled>true</enabled>
<maxDataSize>2005m</maxDataSize>
</offheap>

But now I get another error, when starting tc-server:

But now I have -XX:MaxDirectMemorySize=2147483647...
Am I still missing something?

Thnx

Ok, I think the problem was that I had low memory settings in the virtual machine
