Oracle Enterprise Manager is a set of tools for managing Oracle database (DBMS) products.Enterprise Manager-Your database WatchdogWe use Oracle EM to monitor multiple metrics across several of our databases including running processes, active sessions, tablespace and storage utilization, blocking sessions, and several other critical metrics. Oracle EM solves the issue of having to monitor different databases using scripts or linux reporting tools or mail alerts that can pass on cryptic data, but instead simplifies messages that indicate an issue with the database or database connections.,Creates visuals and graphic indicators for monitoring critical database operations and states. Easily identify problematic connections, performance issues, blocking sessions, and identify sql code or scripts that are degrading database performance. Easily display AWR reporting or ASH analytic's with a few clicks. Easily set up jobs with Oracle scheduler, which you would have to otherwise script directly on the database.,Connections to targets can become lost or dropped, resulting in the application not doing anything when clicking on a link, with no type of indication of what the issues is. Log outs from the console sometime do not complete, and users remain logged in, even after closing the browser session. The timeout function in the console has always been problematic, causing me to have to change the time out setting in the config file, whereas the option to disable the time outs on the console when the option comes up does not work. Selecting the option to disable timeouts still causes idle sessions to timeout.,9,We have been alerted of critical issues that would have otherwise caused significant production downtime due to the comprehensive alert capabilities. Oracle EM has provided many suggestions on fine tuning various SQL to help improve SQL performance as well as database efficiency. We have been able to use visual indicators to monitor critical processes and connections at a glance, without having to spend significant time researching potential issues or performance problems.,,,Microsoft SQL Server, VMware vCenter Server, Toad for OracleOEM Oracle's swiss army knifeWe monitor databases, schedule RMAN backups, provision databases, patching, user management, space management and run reports in BI Publisher.,Gives a big picture view your Oracle infrastructure, and plug-ins for SQL Server, IIS if needed.

Some of the Oracle Product Suites which the customer used were Oracle Database, Oracle SCM, Oracle HCM and Oracle EBusiness Suite.

It is recommended to have all the patches and solutions required for the enterprise manager usage, as any missing patches may cause hindrance going forward.,8,Hassle free management of entire Oracle Product Suite through a single platform has had a very positive impact. Significant savings in time for database administrators as most of their tasks like performance monitoring etc., could be automated. Performance monitoring and sending notification in case of any distress, helps the administrators make an informed and quick decision whenever any issue arises.,Microsoft System Center,Oracle BI Foundation Suite, Infor ERPOracle Enterprise Manager - Robust Environment ManagementI use Oracle Enterprise Manager 11g to manage and maintain all environments used by our teams. Since it's an enterprise tool, it's used across the entire organization. OEM lets us manage users, monitor availability of environments, and deploy RPDs among many other tasks.,Oracle Enterprise Manager lets you control access to an environment for various users across your organization. You can define users, groups, and their credentials. You can define application roles and application policies. This is an excellent functionality which is robust in nature. Oracle Enterprise Manager improves the deployment process on multiple folds using single clicks. You select an RPD, deploy the same and restart your services within a few simple clicks. No need to reach the back end and fall into a tedious loop. Oracle Enterprise Manager notifies the user of any component being down in a graphical manner and points to an exact component being down. This helps in the debugging process.,Simple functionality like one to many mapping of users to groups could be done which would be a useful feature to a DBA/Admin while adding new users. Recovery of logs needs to be more user-friendly. Whenever we face a system downtime issue, exact logs are a little difficult to find. It can get really tedious to point out the problem when looking at generic logs. No cross application navigation is present to other OBIEE products. There needs to be a functionality which can navigate a user from Oracle Enterprise Manager to Oracle BI Analytics. In the RPD Deployment process, there should be a functionality to deploy previously deployed RPDs. In this way, the administrator can keep a track of all previously used RPDs and it's deployments.,9,With Oracle Enterprise Manager we have been able to manage our environments seamlessly with the least problems. It has been robust, graphical and easy to use. We have been able to manage the security of users in a great way using OEM. Every user can be assigned to a group which is a useful feature. Oracle Enterprise Manager provides support to BI Publisher which is a great tool to create customized reports.,

Oracle EM solves the issue of having to monitor different databases using scripts or linux reporting tools or mail alerts that can pass on cryptic data, but instead simplifies messages that indicate an issue with the database or database connections.
  • Creates visuals and graphic indicators for monitoring critical database operations and states.
  • Easily identify problematic connections, performance issues, blocking sessions, and identify sql code or scripts that are degrading database performance.
  • Easily display AWR reporting or ASH analytic's with a few clicks.
  • Easily set up jobs with Oracle scheduler, which you would have to otherwise script directly on the database.
  • Connections to targets can become lost or dropped, resulting in the application not doing anything when clicking on a link, with no type of indication of what the issues is.
  • Log outs from the console sometime do not complete, and users remain logged in, even after closing the browser session.
  • The timeout function in the console has always been problematic, causing me to have to change the time out setting in the config file, whereas the option to disable the time outs on the console when the option comes up does not work. Selecting the option to disable timeouts still causes idle sessions to timeout.
Oracle EM is perfect for monitoring database performance, alerting dba's of critical thresholds, setting up simple tasks using oracle scheduler, identifying problematic scripts or code that are degrading database performance, identifying and resolving blocking sessions and locking sql, and many other database performance monitoring tasks. Where it is a little less suited is configuring backups with non oracle backup systems such as NetApp, monitoring end users connections to the database, some administration tasks such as resizing the SGA or adding datafiles to tablespaces, or changing database configuration files such as the pfile.

Oracle Enterprise Manager is well suited to an organization using multiple Oracle Product Suites and they want a single platform for managing the different Oracle products as well as any third party products. OEM has standard plugins available which will enable easy integration with third-party products. Enterprise Manager may not be well suited for an organization which may not be primarily using Oracle products.

It is click based, intuitive and procedural. If well documented, OEM lets you do the desired task in an easy manner. On the other hand, Oracle Enterprise Manager can only be easier managing Oracle products. It may not work that well with other products from other vendors.
