We prepared a APM 14.1 environment and it was working fine. But suddenly customer broke the database cluster or moved the mdb to some other database server and different instance as well without prior information.So APM is in complete chaos. APM can not start now as it is unable to find the database.
We need to know how we can repoint the APM application to new database server. So the scenario is like initially database server and instance was abc01\ca_itam where mdb was located and now xyz02\ca_itam1 We need to point ITAM application to this xyz02\ca_itam1
Please let me know the necessary steps and what are the files need to be modified to point to mdb database to the new location xyz02\ca_itam1 so that ITAM application can start again.
