How to set java heap size on Openshift Origin PAAS

I have recently got my instance of Openshift Origin up and running. I deployed my first app. I am creating a "diy (do it yourself) cartridge". I added a Cassandra Cartridge to this app and attempted to run it. Unfortunately I am getting the following error:

xss =  -ea -Xss4m -javaagent:./cassandra/versions/1.2.5/bin/../lib/jamm-0.2.5.jar -XX:+UseThreadPriorities -XX:ThreadPriorityPolicy=42 -Xms256M -Xmx256M -Xmn80M    -XX:+HeapDumpOnOutOfMemoryError -Xss180k
[test-dsx.dsx.org 5283b2358000fdc2a100023a]\> 
The stack size specified is too small, Specify at least 228k
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

I am unfamiliar with using PAAS and am trying to figure out how to set my java opts in this environment?

Solution

  • I have fixed it by editing /etc/cassandra/cassandra-env.sh

    I have changed JVM_OPTS="$JVM_OPTS -Xss180k" to JVM_OPTS="$JVM_OPTS -Xss256k"

    and it worked.
