Desidero aumentare la dimensione heap del mio Glassfish. Per questo, io so che posso andare fino a 4GB:Impossibile avviare Glassfish dopo l'aumento della dimensione heap
java -Xmx4000M -version
java version "1.6.0_26"
Java(TM) SE Runtime Environment (build 1.6.0_26-b03-384-10M3425)
Java HotSpot(TM) 64-Bit Server VM (build 20.1-b02-384, mixed mode)
Ho cercato di impostare nel file di domain.xml il -Xmx a 2GB:
<jvm-options>-Xmx2000m</jvm-options>
Ma sto ottenendo il seguente errore:
asadmin> start-domain
Waiting for ... to start .Error starting domain ...
The server exited prematurely with exit code 1.
Before it died, it produced the following output:
Error occurred during initialization of VM
The size of the object heap + VM data exceeds the maximum representable size
launchctl bsexec failed: Inappropriate ioctl for device
lancio il comando con -v opzione dà questo:
