Monitoring plays a major part in mission-critical environments. Most businesses depend on IT infrastructure. As the environments are critical IT administrators need to make sure database and application servers are up and running 24X7. OEM (Oracle Enterprise Manager) plays a critical role in monitoring and administration, For the Oracle database this best product for addressing issues proactively. This is the era most companies thinking about migrating their IT infrastructure to the cloud environment. Oracle Cloud Infrastructure (OCI) is the number one provider for Oracle workloads and OCI has ease monitoring capabilities by introducing OEM (Oracle Enterprise Manager) marketplace image.
If you want to install OEM manually need to download and stage the software. But marketplace image eases these installations.
In this article, I will elaborate on how we can install single-node OEM installation using the OCI marketplace image.
In OCI DBCS Oracle enterprise edition comes with Diagnostics and Tuning Packs. I will talk about the licensing in a separate blog.
If you need to understand more details about the OEM installation, I have mentioned the link which illustrates the OEM 13.5 in OCI infrastructure.
