DX Application Performance Management

Hello Community,

I have installed an agent 10.3 (for WAS) on a linux box to monitor an IBM Liberty application server

I have modified the jvm.options file as follows

# Heap Size
-Xms1024m
-Xmx2048m
-javaagent:/prod/CA/wily4liberty/AgentNoRedefNoRetrans.jar
-Dcom.wily.introscope.agentProfile=/prod/CA/wily4liberty/core/config/IntroscopeAgent.NoRedef.profile
-Dorg.osgi.framework.bootdelegation=com.wily*
-Dcom.wily.introscope.agent.agentName=Liberty

Then I copied the WebAppSupport.jar file in the ext directory of the agent but when i run the application server i get:

[3/29/17 18:26:09:910 CEST] 00004399 com.ibm.ws.webcontainer E SRVE0232E: Internal Server Error. <br> Exception Message: [java.lang.NoClassDefFoundError: com/wily/introscope/agent/AgentShim]
[3/29/17 18:27:10:178 CEST] 000043a8 com.ibm.ws.webcontainer.webapp E SRVE0315E: An exception occurred: java.lang.Throwable: java.lang.NoClassDefFoundError: com/wily/introscope/agent/AgentShim

Do you have any idea where can be the error hiding?

Thanks

Luca:

   In the past this occurred with IBM Liberty Application Servers that were not supported (WAS 8.5 Liberty Profile Applications). Opening a case will be the best way to quick resolution

  Thanks

Jdk is 1.8 the other two i will give you tomorrow

Also for WebSphere, the WebAppSupport.jar file should remain in the common directory.  Please remove it from the ext directory and create a custom service inside the WebSphere console.  

WebSphere - CA Application Performance Management - 10.3 - CA Technologies Documentation 

Hello Community.This is not WebSphere.

Liberty profile has no console and so no custom profile can be added as in WAS.

Anyway this is what i collected related to the jvm version:

java version "1.8.0"
Java(TM) SE Runtime Environment (build pxa6480sr4-20170127_01(SR4))
IBM J9 VM (build 2.8, JRE 1.8.0 Linux amd64-64 Compressed References 20170117_333500 (JIT enabled, AOT enabled)
J9VM - R28_20170117_0200_B333500
JIT - tr.r14.java.green_20170115_130932
GC - R28_20170117_0200_B333500_CMPRSS
J9CL - 20170117_333500)
JCL - 20170125_01 based on Oracle jdk8u121-b13

Hi Luca:

Please try Sergio's suggestion and let us know if that is helpful. If Sergio's suggestion does not help, please open a case as he suggested. Once a resolution is reached, please post the solution to help others that may have this situation.

I have already replied with the solution

I wrote : -Dorg.osgi.framework.bootdelegation=com.wily*

which is wrong

The correct entry is:

-Dorg.osgi.framework.bootdelegation=com.wily.*  there is a full stop (.) MISSING

Thank you for the replies

Hi Luca,

Your settings work in my WLP environment but mine is configured with 1.7 jvm

Suggestions:

1-check that the issue is not due to some encoding/char issues in the jvm.options file. If possible, try to recreate the file again.

2.try setting bootdelegation = to:

a) com.wily,com.wily.*

b) ibm.*,com.ibm.*,com.wily.*

c) ibm.* ,com.ibm.* ,com.wily ,com.wily.*,javax.jms.* ,javax.resource.*

2-for testing purposes, try using a 1.7 jvm, it will hep you confirm that the issue is related to the environment, so compatibility issue

3-run a quick test using latest 10.5

4-check if you are using a framework on top such apache felix, Adobe Granite or any other, you might need to modify other config files such as osgi\felix\conf\config.properties and/or add additional jvm ags, such as -Dsling.bootdelegation.was=ibm.* ,com.ibm.* ,com.wily ,com.wily.*,javax.jms.* ,javax.resource.*

If the problem persists, open a case and attach:

-debug agent logs (if any)

-appserver logs (console, messages and startup)

-core or crash report if any

-verbose classloading log - this is activated by adding the  -verbose:class option/jvm arg

Thanks,

Sergio

OK Everyone.

I solved the case wiriting the jvm.option file correctly.

I wrote : -Dorg.osgi.framework.bootdelegation=com.wily* 

which is wrong

The correct entry is:

-Dorg.osgi.framework.bootdelegation=com.wily.*  there is a full stop (.) MISSING

Thank you for the replies

Case is solved .

Liberty is fully supported by the Introscope Agent 10.3 or at least this release:

java version "1.8.0"
Java(TM) SE Runtime Environment (build pxa6480sr4-20170127_01(SR4))
IBM J9 VM (build 2.8, JRE 1.8.0 Linux amd64-64 Compressed References 20170117_333500 (JIT enabled, AOT enabled)
J9VM - R28_20170117_0200_B333500
JIT - tr.r14.java.green_20170115_130932
GC - R28_20170117_0200_B333500_CMPRSS
J9CL - 20170117_333500)
JCL - 20170125_01 based on Oracle jdk8u121-b13

Thank you all
