Hi robpickering,

for using CSDM , Service Mapping is required?

It is not required.  Service Mapping will automate the creation of service maps, aligned to CSDM, but it is not required to build your own maps.  You CAN build them manually, though keeping them up-to-date then requires management effort long-term.

Hi robpickering,

How should you manage an application like Oracle EBS that has different instances (ie. Oracle EBS - Alice, Oracle EBS - Dario, Oracle EBS - Diego...etc ), then different environment (ie. Prod, Dev, Test, QA etc), then application modules for each instance (ie. Accounts Payable, Accounts Receivable, General Ledger etc..)?

Will it be Oracle EBS in the business application table(parent table) and everything hierarchical to business services table(child table)?

Without performing Service Mapping or implementing Event Management just yet (but plan to), which class should be used to manually enter applications so that they may be used to manually map relationships with their host CIs and made available as CIs to support incident and change management practices? 

Lee,

considering CSDM I would choose 'cmdb_ci_service_discovered' for any Application Services being manually entered. Later you can either build your relationships to Technical Services or any CI's involved in delivering the service later.

Reference the table in CSDM!
