Oracle provides several tools for managing multiple servers. These tools include:
If your server is one of many x86 and SPARC servers that you want to manage from a single interface, you can use the Oracle Enterprise Manager Ops Center. For more details, refer to http://www.oracle.com/technetwork/oem/ops-center/index.html.
If you want to monitor your enterprise servers, you can take advantage of Sun Management Center. For more details, refer to http://www.oracle.com/technetwork/systems/patches/sysmgmt/smc-jsp-138444.html.
If you already have third-party system management tools, the servers can integrate with many third-party tools. For more details, refer to http://www.oracle.com/goto/system-management.
