Ok I do not see any strange things here.. In regard to mem .. this is not a command but merely a question as in how much memory is installed in your box or configured for your installation. that said I cannot help you any further as I have no clue why your commands are not working.. ---

well vi the jvm.options file and adjust it. I would recommend to add memory to your machine. say added 3G then you dont have to change the file. ---
