VCS SAP resource fails to stop SAP OS collector (saposcol) process

Cause
The Veritas agent for SAP NetWeaver provides high availability for SAP and SAP NetWeaver in a cluster.
The agent for SAP NetWeaver is designed to support a wide range of SAP environments, including the traditional Basis architecture and the SAP J2EEWeb Application Server architecture (NetWeaver). The agent also supports standalone Enqueue servers in a distributed SAP installation.
SAP OSCollector:
The Veritas agent for SAP NetWeaver brings SAP instances online, monitors the instances, and bring the instances offline. The agent monitors the system processes and server states, and can shutdown the server in case of a fault. However, the agent does not stop SAP OS collector (SAPOsCol) when offlining the resource.
SAP OScollector (SAPOsCol) runs per system not per SAP instance and it needs to be up before starting any SAP Instance. This is the reason why VCS starts SAP OScollector through the agent before it starts SAP instance. If saposcol is already started, the agent just ignores it and proceeds to start SAP instance.
The reason why the agent does not stop SAPOsCol is, if there are multiple SAP instances running on the same node there is no way to figure out if the resource being offlined is the last SAP instance that is being shutdown. So the agent leaves it running for the other SAP instances that are running on the system.
Resolution
If the system is configured to run only one SAP instance, customers can configure an application resource to manage SAPOsCol process and configure resource dependency between SAP resource (parent) and SAPOsCol resource (child).
If the system is configured to run multiple SAP instances, customer can configure SAPOsCol in a separate service group (parallel) and create service group dependency (local) between SAP instance service groups and SAPOsCol service group.
Issue/Introduction
When SAP OS collector (saposcol) process is added to VCS SAP resource, VCS is unable to monitor/stop the process
