Websphere Java Agent Name Auto Naming error

Products

• CA Application Performance Management Agent (APM / Wily / Introscope)
• INTROSCOPE

Issue/Introduction

On a Java agent installed on Websphere, the autonaming functionality is not working.  It issues this agent log error:

[IntroscopeAgent.Agent] Unable to automatically determine the Agent Name because: The Application Server naming mechanism is not yet available.

Setting up a custom service did not solve the issue.

Cause

Besides custom service, if Java2 Security is enabled on WAS, permissions needs to be added to server.policy. 

Environment

Java agent 10.1WAS 7.0Suse

Resolution

a.) create a custom service, as described in:

https://docops.ca.com/ca-apm/10-1/en/extending/ibm-websphere-application-server-distributed-environments/installing-apm-for-ibm-websphere-application-server-distributed/install-and-configure-apm-for-ibm-websphere-application-server-distributed/creating-custom-service-and-enable-the-pmi-modules/through-the-websphere-application-server-administration-console-manual-setup/configure-a-custom-service-in-websphere

 

b.) If Java2 Security is enabled, it is necessary to modify server.policy:

Please note:

When the following lines are not effective:

// permissions for Introscope AutoProbe

grant codeBase "file:${was.install.root}/-" {

permission java.io.FilePermission "${was.install.root}${/

}wily${/}-", "read";

 

Please use the following:

// permissions for Introscope PMI support 

grant codeBase "file:${was.install.root}/-" { 

permission java.security.AllPermission; 

};
