Oracle Autonomous Database vs. Oracle Enterprise Manager

Scenarios where this is best suited are like where there are not large set of data which has to be analyzed and extracted.It helps in the efficiency of data .It is also well suited for medium size companies where you have to create a common data for everyone. As for large set of data, there can be network latency issues and thus there are some limitations of this software.

I wish I had an option to give it a 9.5 :) OEM Cloud Control is very well suited if you have a system with multiple implementations of Oracle Database Enterprise Edition. If you are willing to pay for the huge license cost which is typical with Oracle, then you will love to use OEM Cloud Control to monitor your entire ERP solution including web servers, applications, network, storage, and physical servers. It is not worth the buck if your's is a small implementation. Your DBA's should be able to work without depending on OEM Cloud Control.

• Robust - this product doesn't have a lot of downtime. It's less prone to errors than some other tools I've worked with.
• Scalable - we can keep adding more things to it. We haven't hit any roadblocks when we've tried to do more with our database.

• Oracle Enterprise Manager is a "one stop shop" for all of our management needs. This is helpful because it minimizes the management of the management software itself. There are less upgrades and connectivity issues to handle. And there are "plug-ins" for additional products we use like Blue Medora's one for PostgreSQL.
• Managing administrative jobs can be burdensome in a shop with dozens of servers and databases. OEM Cloud Control makes it easy since you can view all the jobs for all servers in one place. It is easy to filter on jobs with problems or the like so that you can quickly look at the logs and fix the issues.
• Tuning PL/SQL is much easier using OEM Cloud Control. Most DBAs are familiar with trace files and TKPROF, but not having to do those things at a command line smooths the process out. The graphical interface makes it easier to show developers exactly what the issues are. This makes for less finger-pointing and quicker resolution of performance problems.
• Proactive management is easier using OEM Cloud Control. Before having the gui, I had a collection of scripts that I would have to install on each database server, then set up cron jobs to run them. When Oracle was upgraded, those scripts might have to be updated on each and every server. OEM Cloud Control has those things built in. You can choose exactly which metrics are important to you. And you can keep performance graphs up all day on a second monitor to let you instantly see when something might cause a problem.

• There is no access to the physical host of the DB. This is expected from a managed DB. Everything must be done through the console or via API calls. This is a new learning curve for the DBAs.
• Due to the lack of physical host access, certain features are not supported, such as Transportable tablespaces and Oracle LogMiner.
• Certain special data types, (such as XMLType) are not allowed; be sure the app vendor certifies their product on this platform.

• We also use OEM to monitor SQL Server. However, OEM only provided limited features for SQL Server. It would be nice if we can schedule backup jobs for SQL Server in OEM.
• The ability to run SQL queries. You can't run queries in OEM. I have to go to SQL Developer or SQL PLUS to run. queries.

Autonomous is the way of the future and this is one system which is crucial to any system and is also autonomous. It is self-tuning and self-maintaining which are major advantages.

The product is continuously evolving and new features are added frequently. Management options through the OCI (Oracle Cloud Infrastructure) console and through the command line and API are being enhanced frequently.

It's great! It does everything and anything you would want it to do. It can monitor things which doesn't comes out of the box by adding plug ins to it, for example, you can even monitor Oracle GoldenGate Replication by adding a plug-in to OEM Cloud Control.

I still rate OEM as a must-have tool for central management of Oracle fleet. The pros and cons of the product is prominent. Meanwhile, I also acknowledge that OEM was design about a decade ago. At that time, it did not have the landscape we have today, such as cloud, DEVOPS, machine learning, etc. I hope in future releases, the design will incorporate those features.

Hands down it's the best. It's secure and extremely fast. It also doesn't need a lot of babysitting. It's running itself. It does its job as advertised. This is why I feel everyone should if they haven't already taken a hard look OAD. I feel it's the future of technology at its best. Everyone should be taking notice of how far technology has come and where it's going.

Kibana from Elastic is another monitoring tool that claims to provide very similar information to OEM. It seems to be an information tool rather than a tool that can actually make changes within a database. I think Kibana is more robust for hardware versus database software so it is more suited to that purpose and does to compare to the Oracle Database monitoring attributes of OEM.

• Oracle Autonomous Database has a wide range of warehouses, which is competent and of high performance.
• The transactional processing power that Oracle Autonomous Database outlines are completely important and digital.
• The efficiency of Oracle Autonomous Database data encryption fosters security measures, a form that demands more threat detectors.

• Positive: Alerting features. Without this we would have to be a 24x7 shop with someone always manning the helm. With the alerting feature we can define levels of alerts and only get the most pressing alerts sent out.
• ROI: OEM is free, so the ROI is whatever you make of it.
