Enterprise Manager Cloud Control SNMP and Plug-Ins

Enterprise Manager Cloud Control SNMP and Plug-Ins

Hi, I have been using Oracle Enterprise Manager (OEM or Cloud Control) since it was a client application. (I’m not sure whether it was in the era of Oracle 7 or Oracle 8). In the early stages, OEM was compared to other central monitoring systems (at the time, it was HP OpenView, CA Unicenter, and the like).

Disaster Recovery and High Availability in the Hybrid Cloud

Disaster Recovery and High Availability in the Hybrid Cloud

Technical Note: Disaster Recovery and High Availability in the Hybrid Cloud Although many organizations are using a hybrid cloud model for disaster recovery, this model typically cannot deliver high application availability. This drawback is due to the technical constraints of replication in a cloud topology as well as the complexity of writing code for each application to ensure that high-availability solutions address every possible disaster scenario. Axxana engineers recently conducted tests to investigate and develop a solution that simplifies this process and delivers high availability in the hybrid cloud. This technical note provides details of the testing and describes how organizations can use the proposed solution to automate failover and achieve extremely high availability without requiring human intervention or extensive changes to code—and without impacting the application running in the primary site.
