1.jvm參數
set JAVA_OPTS=-Xms200M -Xmx500M -XX:PermSize=128M -XX:MaxPermSize=256m -verbose:gc -Xloggc:../logs/gclog.log -XX:+PrintGCDetails -XX:+PrintGCTimeStamps -XX:
+PrintHeapAtGC -XX:+PrintTenuringDistribution -XX:+HeapDumpOnOutOfMemoryError %JAVA_OPTS%
rem set JAVA_OPTS=%JAVA_OPTS% -Xint -Xrunjprofiler:port=8849 -Xbootclasspath/a:D:\02.3968\02.softsetup\jprofiler7\bin\agent.jar;
2.Jprofiler集成參數配置
set JAVA_OPTS=%JAVA_OPTS% -agentpath:D:\022F9C~1.396\025CBC~1.SOF\JPROFI~1\bin\windows\jprofilerti.dll=port=8849,nowait
//具體的Jprofiler參數,通過Jprofiler的session 集成嚮導提示設置;
在對本地的應用進行跟蹤時,嚮導提示如下:
Integration type: [Generic application]
Selected JVM: Oracle 1.6.0 (hotspot)
Startup mode: Startup immediately, connect later with the JProfiler GUI
(1) Please insert
-agentpath:D:\022F9C~1.396\025CBC~1.SOF\JPROFI~1\bin\windows\jprofilerti.dll=port=8849,nowait
into the start command of your remote application right after the java command.
A remote session named Remote application on localhost will be created that connects to a running instance of the remote application that is started with the modified start command.
由嚮導可知,將-agentpath:D:\022F9C~1.396\025CBC~1.SOF\JPROFI~1\bin\windows\jprofilerti.dll=port=8849,nowait 加入到啓動文件的JAVA_OPTS可即可
3.配置的具體位置:
