Jam Agent : Could not find required Ocamm agent class file - What does it mean?

When one deploys jamagent, one often sees this error.
"Jam Agent : Could not find required Ocamm agent class file"
What does it mean?

JVMD and ADP(CAMM) have been integrated for some enhanced functionality
called Request Monitoring in EM11g. Only If you are using Request
Monitoring then this error matters, but in general this error has
no impact on jamagent functionality and can be ignored safely.

javax.naming.NamingException: Lookup error: javax.naming.AuthenticationException: No such domain/application: "ClearApp"; nested exception with ADP agent Deployment

While trying to deploy ADP agent on 10.1.3.5 Oracle Application Server, following error is seen on ADP UI:
javax.naming.NamingException: Lookup error: javax.naming.AuthenticationException: No such domain/application: "ClearApp"; nested exception

Environment: Its 10.1.3.5 Oracle Application Server (OC4J) - upgrade from 10.1.3.0 or fresh install with no SOASuite (no BPEL or ESB)

Issue: ADP agent assumes that since its 10.1.3.5 OAS, it has SOA and BPEL libraries and it tries to import them.

Action: 1. Modify $ADP_HOME/deploy/Deployer.ear
a. Unjar $ADP_HOME/deploy/Deployer.ear
b. Modify META-INF/orion-application.xml to remove the following lines
   <imported-shared-libraries>
       <import-shared-library name="oracle.bpel.common"/>
   </imported-shared-libraries>
c. Repackage Deployer.ear

2. Deploy ADP agent using normal steps from ADP UI.

How many JVMD(AD4J) managers are needed to manage various JVMs?

One JVMD(AD4J) manager can manage upto 256 jamagent.
If one wants to manage more than 256 jamagents, one needs to deploy more
JVMD managers.
Multiple JVMD(AD4J) managers are supported as part of patch 9901141.

Not able to add more than 4 resources in the ADP(CAMM) UI

Modify Acsera.properties in $ADP_HOME/config directory.

This property 'ResourceLimit' is in Acsera.properties on the ADP manager, set to 4 by default.
One can change this property, but one needs to ensure to check that the
number of managed entities stays below the amount of memory a single manager can handle.
One should generally try to keep the number of managed entities below 70,000 with a heap
size of around 2GB.
