Need to collect & compare JVM arguments
I have a server.out file which looks like the below...

Code:
JAVA Memory arguments: -XX:ParallelGCThreads=12 -XX:+UseParNewGC -XX:+UseConcMarkSweepGC -Xms2048m -Xmx2048m -XX:PermSize=256m -XX:MaxPermSize=256m -XX:NewSize=800m -XX:MaxNewSize=800m -XX:SurvivorRatio=8 -XX:-UseBiasedLocking -XX:-UseThreadPriorities -XX:LargePageSizeInBytes=128m -XX:+CMSParallelRemarkEnabled -verbose:gc -XX:+PrintGCDetails -XX:+PrintGCDateStamps -XX:+DisableExplicitGC -Dcom.wily.introscope.agentProfile=/opt/app/wlserver_12.1/wilyAgent/wily/IntroscopeAgent.profile -javaagent:/opt/app/wlserver_12.1/wilyAgent/wily/Agent.jar
.
WLS Start Mode=Production
.
CLASSPATH=/opt/app/weblogic_patch.jar:/opt/app/weblogic_patch.jar:/opt/app/jdk/jdk1.6.0_45/lib/tools.jar:/opt/

Question 1:
I need to read all the JVM args in variables and compare them like
if -Xms is not found display " -Xms not Found" and if Found then compare if valueof-Xms <= valueof-Xmx echo "Good" else echo "Bad".

Question 2:
How will i understand that all the JVM arguments have been read from the server.out

HINT:
First parse using "-" as the delimiter, then for each argument found (23 of them), parse each using ":".

For example, assuming JAVA MEMORY ARGUMENTS up to the Agent.jar file is one line...

Code:
egrep "^JAVA Memory arguments" server.out | awk -F\- '{print NF}'
23

I just counted the arguments. Your script should loop NF times and parse those arguments for ":" and handle cases of -Xmsxxx.
