Decrease required memory

[Erik Svensson]

Hi,

Is it possible to decrease the memory required by the transactor? I'm
trying to run the free transactor on a EC2 Micro instance, which doesn't
have enough memory. I have tried to change the object-cache-max setting to
128m, but it had no effect.

Relevant error message:

Launching with Java options -server -Xms1g -Xmx1g -XX:NewRatio=4
-XX:SurvivorRatio=8 -XX:+UseConcMarkSweepGC -XX:+UseParNewGC
-XX:+CMSParallelRemarkEnabled -XX:CMSInitiatingOccupancyFraction=60
-XX:+UseCMSInitiatingOccupancyOnly -XX:+CMSScavengeBeforeRemark

You will need to change more than object-cache-max. Notice the -Xms1g and
-Xmx1g, both asking for a gig of RAM, which is more than micros have.

Don't expect much write performance. Micros will run, but they are not a
supported configuration.

Cheers,
Stu
