Issue/Introduction

The following errors are thrown in agent logs after activating crossjvm ("introscope.agent.websphere.crossjvm=true") and Cross Process Transaction is not working.

[WARN] [IntroscopeAgent.Agent] Unable to create jndierrorskip.pbd, turn on DEBUG for more details

Environment

DX APM 10.x

Cause

"Cross-Process Transaction Tracing" feature enables you to trace all of the operations that take place in a transaction, including transactions that cross JVM boundaries on computers with compatible JVM versions.  

You can enable Cross-Process Transaction for the below 2 scenarios:

a) If you using Websphere Java RMI to call EJBs
-Turn on Work area service : Go to Websphere console, select Business Process Service > Work Area Service, make sure "Enable service at service startup" is selected
-Open the IntroscopeAgent.profile, set introscope.agent.websphere.crossjvm=true
 
b) Enable cross JVM via webservices
This is achieve using the SOA Performance Management agent extension. It supports transaction tracing over the following protocols : SOAP (enabled by default), HTTP and JMS. This agent extension is enabled by default.

Resolution

1. Turn on Work area service in WebSphere admin console:

 -Go to WebSphere Administration console

 -Click Servers \ WebSphere Application servers \ <your appserver> \ Business Process Services > Work Area Service

 
-Check the option "Enable service at server startup"

2. Make sure to configure the custom service in WebSphere

-Go to WebSphere Administration console

-Click Servers \ WebSphere Application servers \ <your appserver> \ Administration \ Custom Services.

-Click New and enter the below values:

-Check the option "Enable service at server startup"

-Specify the name of the custom service class = com.wily.introscope.api.websphere.IntroscopeCustomService

-Specify the fully path of the WebAppSupport.jar

 

3. Open the IntroscopeAgent.profile

-Add the following parameter introscope.agent.skipjndierror.location={path to the hotdeploy folder in the wily folder structure}

-Save the Agent.profile

4. Restart the Agent.
