Subject [Cassandra Wiki] Update of "RunningCassandra" by JonathanEllis
Date Sat, 04 Jul 2009 16:42:25 GMT
Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Cassandra Wiki" for change notification.

The following page has been changed by JonathanEllis:

New page:
When you run bin/cassandra, by default it takes its JVM options and configuration directory
from bin/

Among other things the defaults include a maxiumum heap size (-Xmx) of 1GB, which you will
probably want to increase for production use.

It also tells the JVM to listen for a remote debugger on port 8888, and for JMX on port 8080.

You can override the options script to use with CASSANDRA_INCLUDE.  E.g.,

$ cp bin/ /tmp/
$ vi /tmp/
$ CASSANDRA_INCLUDE=/tmp/ bin/cassandra
