If you run ChemAxon applications from command line (through ChemAxon shell scripts) then, apart from the application specific parameters, you can specify some options to Java VM (like Java heap size).

For example,

    mview -Xmx128m huge-file.sdf

sets the max memory of the Java VM to 128Mb (the default value is 64Mb). This can be useful if we want to load a huge molecule file into the MarvinView application.


-clientto select the "client" VM
-serverto select the "server" VM
-Xmx<size>set maximum Java heap size
-Xprint help on non-standard options. Different Java VM-s support various non-standard options. After printing the help, the Java VM exits immediately. Thus, the application will not start if the command line includes this option.
The ChemAxon shell scripts can evalute all non-standard options starting with -X.
