Oracle Enterprise Manager

Oracle Enterprise Manager (OEM) is a tool supplied by Oracle that provides an easy-to-use, graphical approach to managing one or more databases. It combines a number of distinct facilities into an integrated platform for managing Oracle products. From the Oracle Enterprise Manager’s console, the DBA may be able to:

  • Administer, diagnose, and tune one or more databases

  • Distribute software to multiple servers and clients

  • Schedule jobs on multiple nodes at varying times

  • Monitor objects and events throughout the Oracle network

  • Customize the display using graphic maps and groups of network objects such as nodes and databases

  • Administer Oracle parallel servers

  • Integrate participating Oracle or third-party tools
