Idea ID 2773459
A goal of the CMS is to provide relevant information to processes like Incident or Change management. Looking from a perspective of a business application using an application resource, like an Oracle Schema, the process requires to know which Schema is being used. The issue we're running into has to do with Oracle RAC or Oracle Dataguard, and to some extent MS-SQL Always-On: How to link a business application to an application resource?
The perspective of the business application is to know which Schema it is using; today, the discovery runs on a Node, which returns a Composition Oracle, which in turns return a Composition Schema. In a Oracle RAC/DG environment, we end up with as many Schema as there is Oracle. This is the issue, in RAC, from an Oracle DBA point of view, there is only one Schema, being provided by multiple Oracle.
What I’m asking is that would it be possible to change the discovery process to return a single instance of Schema when only a single instance exists from the point of view of the Running Software? This has an impact of the discovery, reconciliation, relationships type.
The benefit to the processes would be to have a single CI to manage, the configuration manager would be able to link to their Schema based on their business application perspective, DBA would consider the CMS to be more realistic, ITIL processes would be able to use them in their processes.
(We could also apply this philosophy to any types of application resource which has multiple paths, like Cloud based applications, Web Servers, ...)
2020-04-13: I did have a conversation with some internal people. The suggestion so far is to add a CI to link the Schema's together, and then have this new CI linked to the Business Application.
- Add a new CI of CIT CICollection
- How should it be created? We could use an enrichment rule?
- Link ther CICollection to BusinessApplication and to Schemas
- Should the link be Membership? As to show the logical relationship, not a discovered one.
