Java Out of memory error

alcatros

Hello Guys,

I have the following problem, while using my program in windows to load aprox 1 mio records it works, it will use about 250 mb Ram, on the other hand on Unix i get the following Problem on a AIX machine. Is there some Java Setting which needs to be adjusted in order to get no out of memory exception? The memory the machine has free ist 5 GB still, so it can't be a true output. It seems to have some other problem.

Has Somebody a hint? Googling didn't turn out useful.

Thanks,

Alcatros

Which JVM implementation are you using? If you are using the Sun/Oracle JVM you can define memory options on application startup via -Xmx (I think).

All HotSpot options can be found here: http://www.oracle.com/technetwork/java/javase/tech/vmoptions-jsp-140102.html

Eh kleine Nebenfrage, warum versuchst du in einem deutschen Forum englisch zu sprechen, wenn du's nichtmal kannst...

..und noch vor ein paar monaten auf deutsch gefragt hast, wie alle anderen in einem deutschen forum auch..
