Please provide a little more information... like where are you trying to start the JVM, under TSO OMVS?
Do you know how much storage you have available above the line? For -Xms100m you probably want at least 140m. You might try a tool like Mark Zelden's REXXSTOR exec: http://home.flash.net/~mzelden/mvsutil.html (BTW: a *default* setting of 100M max heap size seems odd to me unless *all* of your java applications need a large heap. It is best not to use a max heap size much more than you need) If you use the JZOS batch launcher, which ships with the SDK, you can set "LOGLVL='+D'" and you will get some debugging information, including a display of the LDA storage map.
