使用jython来对websphere进行修改

通常我们会使用jctl和jython语言来对webshpere服务器进行管理。

例如，这有一段websphere有关jvm的配置

<processDefinitions executableTarget="com.ibm.ws.runtime.WsServer" executableTargetKind="JAVA_CLASS" workingDirectory="${USER_INSTALL_ROOT}" xmi:id="JavaProcessDef_1295834151746" xmi:type="processexec:JavaProcessDef">
    <execution processPriority="20" runAsGroup="" runAsUser="" xmi:id="ProcessExecution_1295834151746"/>
    <ioRedirect stderrFilename="${SERVER_LOG_ROOT}/native_stderr.log" stdoutFilename="${SERVER_LOG_ROOT}/native_stdout.log" xmi:id="OutputRedirect_1295834151746"/>
    <monitoringPolicy autoRestart="true" maximumStartupAttempts="3" nodeRestartState="STOPPED" pingInterval="60" pingTimeout="300" xmi:id="MonitoringPolicy_1295834151746"/>
    <jvmEntries debugArgs="-Dcom.ibm.ws.classloader.j9enabled=true -agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=7777" debugMode="false" disableJIT="false" genericJvmArguments="-Xquickstart" runHProf="false" verboseModeClass="false" verboseModeGarbageCollection="false" verboseModeJNI="false" xmi:id="JavaVirtualMachine_1295834151746"/>
  </processDefinitions>

 

现在我们就用jython来读取这些属性

cell=AdminControl.getCell()
node=AdminControl.getNode()
server="server1"
nodeId="/Cell:"+cell+"/Node:"+node
serverId=nodeId+"/Server:"+server
jvmId=serverId+"/JavaProcessDef:/JavaVirtualMachine:/"
outputId=serverId+"/JavaProcessDef:/OutputRedirect:/"

def readAttribute():
	"read the attribute of jvm"
	global AdminConfig
	jvm=AdminConfig.getid(jvmId)
	print jvm
	gen=AdminConfig.showAttribute(jvm,"genericJvmArguments")
	print gen
	output=AdminConfig.getid(outputId)
	print output
	filename=AdminConfig.showAttribute(output,"stdoutFilename")
	print filename
	jvms=AdminConfig.list("Property",jvm).split(lineSeparator)
	for n_jvms in jvms:
		name=AdminConfig.showAttribute(n_jvms,"name")
		value=AdminConfig.showAttribute(n_jvms,"value")
		print name+" >>>>  "+value
	
readAttribute()

 

运行上面代码我们将得到属性"genericJvmArguments“的值，jvm 输入日志路径。和jvm属性值。而对这些值的修改，则通过AdminConfig.modify()来修改即可，再AdminConfig.save() ，就ok了。
