I am setting up glassfish v3 for a production deployment. This is what my jvm-options look like:
<jvm-options>-XX:+UnlockDiagnosticVMOptions</jvm-options>
<jvm-options>-XX:+LogVMOutput</jvm-options>
<jvm-options>-XX:LogFile=${com.sun.aas.instanceRoot}/logs/jvm.log</jvm-options>

<jvm-options>-XX:+AggressiveHeap</jvm-options>
<jvm-options>-Xmx2048m</jvm-options>
<jvm-options>-Xms2048m</jvm-options>
<jvm-options>-Xss128k</jvm-options>
<jvm-options>-server</jvm-options>
We are running Solaris 10 on a 64-bit 2-Quad Core (8 CPUs) x86 16Gb RAM machine. We have a mysql server running that uses no more than 2Gb (worst case scnario) but need 3 domains/instances for glassfish. The problem is if I set Xms to less than 2048m, glassfish says initial heap is too small. Any comments on the jmv options and any idea why I cant set a lower Xms value? I have a feeling that it has something to do with AggressiveHeap ?
