3. Why are WebSphere nodes in a cluster failing to start, even if one node is not instrumented?  TEC614151
http://ca.com/us/support/ca-support-online/product-content/knowledgebase-articles/tec614151.aspx

 

Description: The IBM Class Sharing feature, which is enabled out of box, causes classes to be stored locally. The classes could contain bytecode instrumented by the Agent. So even if the Agent is removed, those references are still loaded and can cause startup issues. This article addresses how to resolve this issue and what can be done to configure Class Sharing properly.

14. What is the difference between the files Agent.jar, AgentNoRedef.jar, AgentNoRetrans.jar, AgentNoRedefNoRetrans.jar?  TEC604200
http://ca.com/us/support/ca-support-online/product-content/knowledgebase-articles/tec604200.aspx

 

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

16. How to Configure CA APM to use LDAP Authentication (Introscope and APM CE)TEC595290
http://ca.com/us/support/ca-support-online/product-content/knowledgebase-articles/tec595290.aspx

 

Description: CA APM gives you choices for securing and authorizing access to some or all of the features and domains of the Enterprise Manager and Workstation. Using LDAP, you can authenticate user and group access with CA APM while maintaining user and group authorization in local configuration files.

There are 3 ways to secure CA APM

Local  - Users and groups are both authenticated and given authorization via local configuration files maintained on the Enterprise Manager server.

LDAP  - Users and groups are authenticated by LDAP directories but authorized by local configuration files maintained on the Enterprise Manager server or CA EEM.

EEM  - Users and groups are both authenticated and authorized by a CA EEM (CA Embedded Entitlements Manager) server for CA APM activities.

This article discusses how you can integrate CA APM with your own LDAP directory for authentication to the APM Workstation and Enterprise Manager.


17. How to implement CA EEM and LDAP for Authentication and Authorization of CA APM TEC593939
http://ca.com/us/support/ca-support-online/product-content/knowledgebase-articles/tec593939.aspx

 

Description: Using CA EEM, CA Embedded Entitlements Manager, in conjunction with a supported LDAP Server, it is possible to eliminate manual updates to CA APM configuration files every time you need to add a new user, change a password or update access permissions.

CA EEM allows you to utilize a supported LDAP server for authentication while it controls authorization policies for LDAP users and groups. If you do not use LDAP, EEM can even perform authentication duties using the secure, proprietary CA Directory, which is included.

CA EEM is bundled with CA APM and is available from the APM Product Downloads Page on support.ca.com. It can be installed on the same or a separate server as the Enterprise Manager. CA EEM supports many CA products, serving as a single point of control for authentication and authorization.


18. Upgrading CA APM agent custom PBDs to the 9.1 new agent architecture TEC566300

19. Using the APM Database without APM CE (CEM ) creates large empty data partitions. TEC614229

http://ca.com/us/support/ca-support-online/product-content/knowledgebase-articles/tec614229.aspx

 

Description: Note that this applies ONLY applies when the following three conditions are met:
1. APM CE (CEM) is not deployed. So the APM database is only being used for triage map operations.

2. The APM database is using Oracle version 11gR2 and later.

3. There is a need to save disk space instead of creating empty partitions


20. .NET perfmon, high CPU utilization, and the perfmoncollectoragent TEC604893
http://ca.com/us/support/ca-support-online/product-content/knowledgebase-articles/tec604893.aspx

 

Description: Are you seeing high CPU usage on a .NET agent?

Are you using the perfmoncollectoragent?

To verify that perfmon is causing high CPU utilization, disable perfmon. Knowledge Document:

https://support.ca.com/irj/portal/anonymous/redirArticles?reqPage=search&searchID=TEC596327

explains how to diagnose perfmon as the root cause.
