Description:

What is the difference between the jar files:

1. Agent.jar - canRedefine and canRetransform settings are both set to true
2. AgentNoRedef.jar - canRedefine setting is set to false (no longer used)
3. AgentNoRetrans.jar - canRetransform setting is set to false (no longer used)
4. AgentNoRedefNoRetrans.jar - canRedefine and canRetransform settings are both set to false. With the introduction of the retransformation option in the IBM JVM 1.6 this jar was developed to address performance issues being experienced by some clients and replaces the AgentNoRedef.jar and AgentNoRetrans.jar

Solution:If you are using an IBM JVM the recommended jar file to use is AgentNoRedefNoRetrans.jar - the reason that this jar file can be used with IBM JVM 1.5 even though it does not have the retransformation option is due to the fact that this setting will be ignored since it does not exist.

The files, named AgentNoRedeNoRetrans.jar and IntroscopeAgent.NoRedef.profile, are located in the <Agent_Home>/wily and<Agent_Home>/wily/core/config directory respectively.Note: If you are using the AllAppServer agent distribution, the alternate profile is namedIntroscopeAgent.websphere.NoRedef.profile.Effects of using AgentNoRedefNoRetrans jar:As a result of using the above files and syntax, metrics are no longer reported for:

• System classes
• NIO (Sockets and Datagrams)
• SSL
