Generating thread dump/java core using WSAdmin script

You can generate Thread Dump or Java core manually using the following WSAdmin Script

def generateThreadDump(serverName):
serverJVM = AdminControl.queryNames("type=JVM,process="+serverName+",*")
AdminControl.invoke(serverJVM,"dumpThreads")

generateThreadDump("server1")


The generateThreadDump() method takes server name and generates thread dump for that server. Once the thread dump is generated you can find out the location of the thread dump from native_stderr.log file. This is sample of the messages from my native_stderr.log
