Working with Tools

This section shows you how to debug WAS through Eclipse, how to use IBM Support Assistant Workbench and explains the JMX connection setup.

Debugging WAS through Remote Eclipse

Procedure

1. Use the following as JVM startup parameters:

-Xdebug -Xnoagent -Djava.compiler=NONE -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=7778

2. Define an Eclipse Remote Java Application configuration.

Using Health Center

Procedure

1. Download IBM Support Assistant Workbench.
2. Go to Update > Find New > Tools Add On menu. Click JVM Based Tools and select Health Center. 
3. Start Health Center through the following screen on WebSphere by adding the –Xhealthcenter option to the Generic JVM arguments.



NOTE: Fix pack 7.0.0-WS-WASSDK-WinX64-FP0000011.pak must be applied for this to work, otherwise your server will crash on startup with an invalid JVM option.  To correct it, you must modify server.xml.

Setting up JMX Connection on zOS

Procedure

1. Add the following properties in JVM:

   -Dtafj.home=/temenos/tafj -Xtrace:none -Dcom.ibm.xml.xlxp.jaxb.opti.level=3 -Xgcpolicy:gencon -Xnoclassgc -Xlp1M -Djavax.management.builder.initial= -Dcom.sun.management.jmxremote -Djava.rmi.server.hostname=10.3.42.3 -Xdump:java:events=throw,filter=java/lang/NullPointerException[jVarImpl.verifyFileDescriptor]

2. Add the following properties in management.properties (common settings for all JVMs):

   com.sun.management.jmxremote.port=9999

   com.sun.management.jmxremote.authenticate=false

   com.sun.management.jmxremote.ssl=false
