关于 jvm 在aix 系统上面 启动设置 求救了？（在线等急）

服务器 系统是 
java version "1.4.2"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2)
Classic VM (build 1.4.2, J2RE 1.4.2 IBM AIX build ca142-20070317 (SR8) (JIT enabled: jitc))java启动设置的参数 
java -Xms1000m -Xmx5000m -Xss2048K -Xoss2048K -classpath "$lib_path/ant-1.6.5.jar:$lib_path/antlr-runtime-3.0.jar:$lib_path/ant-nodeps-1.6.5.jar:$lib_path/classes12.jar:$lib_path/core-3.2.3.v_686_R32x.jar:$lib_path/drools-ant-4.0.4.jar:$lib_path/drools-compiler-4.0.4.jar:$lib_path/drools-core-4.0.4.jar:$lib_path/drools-decisiontables-4.0.4.jar:$lib_path/drools-jsr94-4.0.4.jar:$lib_path/janino-2.5.10.jar:$lib_path/jsr94-1.1.jar:$lib_path/jxl-2.4.2.jar:$lib_path/log4j-1.2.12.jar:$lib_path/mvel14-1.2.21.jar:$lib_path/xercesImpl-2.4.0.jar:$lib_path/xml-apis-1.0.b2.jar:$lib_path/xpp3_min-1.1.3.4.O.jar:$lib_path/xstream-1.2.2.jar:$class_path" com.nl.exactmkt.drools.sc.ExactMKTRule
系统上面 的内存设置
weblogic@basemkt1[/emkttest/weblogic/rule]ulimit -a
time(seconds)        unlimited
file(blocks)         unlimited
data(kbytes)         unlimited
stack(kbytes)        4194304
memory(kbytes)       2048000
coredump(blocks)     4097151
nofiles(descriptors) unlimited然后我就在窗口中修改了一下 
weblogic@basemkt1[/emkttest/weblogic/rule]ulimit -m 5000000
weblogic@basemkt1[/emkttest/weblogic/rule]ulimit -a
time(seconds)        unlimited
file(blocks)         unlimited
data(kbytes)         unlimited
stack(kbytes)        4194304
memory(kbytes)       5000000
coredump(blocks)     4097151
nofiles(descriptors) unlimited启动我的java程序后 就出现 
[ Incompatible initial and maximum heap sizes specified: ]
[     initial size: 1048576000 bytes, maximum heap size: 947912704 bytes ]
[ The initial heap size must be less than or equal to the maximum heap size. ]
[ The default initial and maximum heap sizes are 4194304 and 67108864 bytes. ]
Could not create the Java virtual machine.请问一下 是不是 还需要设置什么？ 我没有设置的
