Discovering Exadata Cloud in Enterprise Manager: Quickly and Easily

Running a database up in the cloud is no longer a new concept.  Oracle has taken their Exadata Database Machine and provides a couple different Exadata Database Machine cloud options.  These options are referred to as Oracle Exadata Cloud Service and Oracle Exadata Cloud Machine (collectively referred to as Exadata Cloud).  Moving a database into the cloud does not remove the requirement for proper monitoring of that database.  For those that have depended on the...

Don't get bit by a newly discovered bug in EM 13c DR environments using alias hostnames

Do you have a 13c EM environment that is setup for disaster recovery using alias hostnames for the OMS servers?  If so, you need to know about an issue that exists when trying to do tasks such as provisioning, staging of directives, etc.  This issue occurs because certain tasks in EM require the target agent to communicate back to the central agent running on the OMS server.  To do this, the target agent must be able to resolve the hostname of the central agent in which it is...

Relocating targets with EM 12c

Multi-Agent targets Some targets (like RAC databases, clusters, FMW domains etc) are considered 'clustered' and have failover build into them 'by design'. Enterprise Manager handles those targets in a special way: They are marked as 'multi-Agent' targets: They are discovered on all Agents of the 'cluster' or 'set of hosts' they can run on. The OMS will decide which Agent will do the actual 'monitoring' of that target in question. (OMS mediation) If that Agent goes down or becomes...
