Oracle Enterprise Manager Reviews

Enterprise Manager is a single window plane of glass which allows one to look into every aspect of the systems deployed in an organization. We use it to mange our internal infrastructure, including Oracle Exadata, Oracle Exalytics, Oracle VMs, ERP solutions (such as Oracle Applications and Fusion Middleware, like SOA and AIA), and Oracle Linux servers.

This solution allows us to quickly drill down when there are issues. It helps us monitor solutions both in-house and at our customer premises. We use it extensively for performance tuning testing, monitoring, and configuration.It is also the only tool that can monitr all apects of Exadata , Exalogic and other Oracle engineered systems.

The database performance monitoring features are very useful and allow us to quickly zero in on DB-related issues.Exadata storage server and Infiniband switches can be viewed from the GUi in OEM which cannot be done in other tools . The ability to deploy metric extensions makes this tool extensible for our custom monitoring also.

The product is pretty comprehensive, but quite resource hungry. This might be due to the majority of the application seemingly being written in Java. 

Also, better mobile access would be useful.

More than ten years.

There were some issues with the software due to its resource requirements. Be careful to follow the recommended sizing guidelines.

No issues. It is very scalable. Ther are also comprehensive documents for both HA setup and DR setup. One caution is that for DR setup additional licensing is required.

We have not faced any major issues with the product. Auto deployment may be difficult in certain customer environments due to the firwall port issues but in those cases manula deployment of agents is an acceptable workaround. We originally had some timezone related issues due to the fact that my home timezone changed from Asia/Calcutta to Asia /Kolkata but this is no longer an issue

Oracle Enterprise Manager is the only solution which can monitor and drill down into the inner workings of engineered systems, like Exadata and Exalytics. Thus, we had to use this system when we deployed those systems. Being system integrators we work with a wide variety of tools however this tool has very wide support across all of oracles hardware and software.

Setup can be complex depending on the options required. There is a simple express install and a much more elaborate enterprise class setup, which is also possible.

Our in-house team has the capability to implement this (with customers).

This solution was the only one which allows us to monitor all our solutions from one interface. However, the optional packs are expensive, hence your mileage may vary. Please take advice before choosing what exactly to purchase. Remember that the base configuration is free to monitor any Oracle product.

Evaluate your requirements carefully. Elaborate DR and HA setup of OEM can become expensive. 

Be careful to only enable the packs for which you have a license as this is an issue we see time and again. I.e., customers who do not understand the licensing model have not turned off access to packs that they are not licensed for, then get into legal issues for it later.

None of the other options out there have the breadth and depth of this solution. This is the only solution which can drill down to the cell level of an Exadata system. Finally, it has modules available for almost every Oracle product available.

If you are an Oracle shop, or even an Oracle SI, then familiarity with Oracle one stop management solution is an imperative. Everything ties into this solution, so it has become a de facto standard for Oracle-based software given that the base is free to use with Oracle products. There is no downside to deploying this solution in your data center.

On-premises

Other

The tool provides valuable visibility into Oracle websites, offering information such as session counts, long-running transactions, etc. We're even working on developing our services to enhance monitoring capabilities within Enterprise Manager further

What I like most about Oracle Enterprise Manager are its features, particularly the active session history. It provides insights into SQL, and I use it regularly to identify potential issues. Automation is incredibly useful when setting thresholds and notifications to manage processes effectively. Recently, we've set up Oracle Resource Manager. 

The value of using Oracle Enterprise Manager lies in the visibility it provides in your database infrastructure. It serves as a solution for database management, including monitoring, notifications, and troubleshooting.

Improving the integration speed would be beneficial, as the current Java-based system can sometimes result in slow responses. Enhancing performance overall would also be valuable.

I have been using the product for 10 years. 

The tool is stable. 

We are currently working with at least five large banks that have deployed or are ready to deploy Oracle Enterprise Manager. We use various metrics and diagrams to monitor their processes and understand what is happening within their systems.

I haven't contacted the technical team yet. 

You need to familiarize yourself with the concepts and additional requirements for deployment. Cloud services are a bit different from on-premise setups. You need to understand some extra features and technology, which can lead to additional challenges.

As far as I know, you do not pay for Oracle Enterprise Manager separately. You can use Enterprise Manager for free if you already have an Oracle license for your database.

Currently, we're considering a hybrid cloud environment for our customers. While one of our customers has been utilizing this for several years, we're now exploring the pricing model to determine its suitability for different customer segments. While banks may not fully transition to the cloud, smaller financial companies or universities could benefit from this model.

My recommendation would be for those interested in starting to use Oracle Enterprise Manager to take advantage of its free version. I rate the overall solution an eight out of ten. 

Hybrid Cloud

We use the this GUI  tool for small industries and enterprises. It acts as a Server controller and monitoring of its mostly activities  

It is a GUI Tool that is used to check the live severs monitoring activity 

Oracle Enterprise Manager helps to control servers.Mostly its load and performance and its disks utilization

The tool's pricing is costly.

I have been using the product for 23 years. 

It is a stable thing

My company has four to five users for Oracle Enterprise Manager. It is a  scalable product 

We raise our questions on oracle  Metalink whenever we are stuck. We face problems on the ERP application level and not the database level. 

Positive

We use multiple tools like Grid, oracle OEM and Toad is also helpful for  monitoring and live activity specially for DDL commands. 

The tool's deployment is easy. If you deploy it, Oracle Enterprise Manager becomes a part of your installation process. After completing the server installation, you get control of Oracle Enterprise Manager. This process involves creating your account, password, and operating system password. With these credentials, you gain full command and control over it. The tool's maintenance is easy. Maintenance is critical for Oracle Enterprise Manager, especially considering it provides full server command and control. This is particularly relevant for Linux units, as most users opt for Linux over Windows for security reasons. We have two to three resources handling maintenance. We have around 50-100 servers. If your organization has ten servers, one person is enough to handle it. 

We have 95% inhouse software development team. just 5% have outsource product these are small level application. 

Initially, our deal was for three years, and we extended it to five years. Oracle solutions are very costly. We have totally our solution and including hardware with its license. we have no product either it is a hardware or software is not without its license. we have our separate department whose is deal such type of license cost 

It is not so much mandatory because this tool has limited features not all types of features

I would recommend the product to friends and colleagues, especially those using Huawei products. Huawei is not good in terms of performance. I rate Oracle Enterprise Manager a ten out of ten. 

Private Cloud

Amazon Web Services (AWS)

We use the solution for monitoring and alerting.

The job subsystem, monitoring subsystem, alerting, grouping of targets, and reporting features are valuable to us. Sending alerts based on groups is also useful. The product serves the purpose that we are using it for. We are very satisfied.

The product must improve its support team.

I have been using the solution for 12 years.

We have around 300 customers. Almost every customer that is present in our environment is using the product.

Support for the internal workings is not well documented. The solution’s engineers have to run after the senior engineers whenever any complex issue occurs. It causes a delay when we create a support request.

Neutral

The initial setup is complex. It requires two server setups. It took us five to six hours to deploy the solution due to its complexity and the number of components present.

We need two DBAs to deploy and maintain the solution.

I am not sure about the pricing. The pricing terms change every year. It depends on the customer’s infrastructure and environment.

We need to install plugins for integration. It is pretty much covered within the tool. It requires additional licensing, and we do not require integration. I would recommend the solution to others. We can use it for monitoring and alerting purposes, and it is a very good tool. Overall, I rate the tool a nine out of ten.

On-premises

Web services and environment status by ping service and SOAP & Restful web service request. check on JVM and other transaction monitoring.

This product helps to reach the cause of an outage or unstable system in production and in handling such situations. It provides an easy way to reach the root cause of the problem and to resolve it asap. It helps in CPU utilization monitoring as well as thread and memory management.it helps in building emergency respond team for monitoring team. At some point monitoring team does not need to engage operation team as feature like restart of server can done through this tool.

Max use was server monitoring and operations of applications. This helps handling of critical situations in a production and support for the customers.

Customization for double secure / nonce based / token based Business Transaction Management. Where you can monitor DB calls as well as Web service calls under firewall.

One to four years. 

No

Yes... sometimes it does not trigger an alert in case of an issue. Trying to fix it with custom build changes.

Customer Service:

2 on a scale of 1 to 5 (1=worst , 5=best)

Technical Support:

2 on a scale of 1 to 5 (1=worst, 5=best)

We still have t-mart alert system. We switched to this one to monitor systems in detail. T-mart alert is just a replication of a user's behavior which does not show the cause of the issue.

Straightforward with all necessary steps mention in the online documentation.

Together as a one team. 3 on a scale of 5.

License version..does not cost too much due to license and agreement between vendor and company.

No. We use other Oracle products like Java, Weblogic Portal, Weblogic Server, Sun One web servers, Solaris servers and Linux.

If you have a license contract with Oracle and if you have a lifetime agreement on service on any product from Oracle then this product is worth using. Otherwise it's best to explore the option of using an open source product. Not worth it for start up companies.

Hybrid Cloud

When my company has to deal with complex customers along with the many products from Oracle, we use Oracle Enterprise Manager as a dashboard to get a view of all the implementations of Oracle products.

The fact that Oracle Enterprise Manager is an expensive solution is a matter of concern and needs to be considered for improvement.

I have been using Oracle Enterprise Manager for many years. I am a seller of the solution for my company.

My company's technical team uses the solution since it is stable. It is a stable solution.

It is a scalable solution. So far, my company has not faced any issues with the scalability part of the solution.

Around six or seven customers of my company use Oracle Enterprise Manager.

Whenever my company needed assistance, Oracle's technical support has been helpful. Since my company knows people from Oracle, we get support from Oracle's local team, too.

From whatever knowledge I have gathered from my team, I can say that the beginning phase of the initial setup process of Oracle Enterprise Manager can be complex. Lately, my team has been using Oracle Enterprise Manager as any other solution.

The solution is deployed on an on-premises model.

Oracle Enterprise Manager is a free-of-cost solution. Oracle Enterprise Manager can be expensive only if you go for its licensing part.

I recommend the product to those who plan to use it.

I rate the overall tool an eight out of ten.

On-premises

Monitoring, EM Jobs and IP/BIP Reports

My company either is outsourced DBA or secondary DBA support. I am able to use EM12c to standardize what would be an almost unattainable goal without the product. With standardized monitoring templates and incident rule sets, we are able to consistently monitor, manage and alert all DBAs in each group to the same level SLA for our customer's needs.

We would love to see a migration utility for EM jobs. I've been a proponent for consolidating all database tasks from outside schedulers into Enterprise Manager Jobs. The challenge is if there is an upgrade to EM12c, this must be migrated manually and the interface is almost exactly the same as we had back in EM10g. Some improvements would be greatly appreciated.

1 year and 3 months

I do have a number of clients who's primary OS environment is Windows. They have virtualized with this OS and release 3 build of EM12c experienced serious java failures and I had to change the project sign off to release 2. It was a huge "hit" to the initial credibility of EM12c when having to return to two different clients and ask to downgrade to the previous release.

The stability of the product is excellent. It is sensitive to network issues, but the problem lies in the network, not EM12c.

High heap usage is a common complaint during top EM job utilization. This is a tuning issue over a scalability issue, but it is impacting to the one receiving the incident notifications.

Customer Service: 2 out of 5. I often choose to open an SR as a last resort. My clients just don't have the time it requires to go through an SR process.Technical Support: I would give it a 3 out of 5. There are some service reps that are very helpful and know the product. There are others that I feel I'm wasting my time with and my clients only have me for a set hours per month, so I don't have time to waste.

Some of my customers had either customer scripts scheduled through cron schedulers or Windows schedulers. Having all jobs running within the EM12c eases management for any DBA who might not be familiar with my coding style or know where jobs are scheduled. All they need to know is how to log into the EM12c for that client and they are able to mange the environment when I'm unavailable.

Very simple and well documented.

In house- I was the one who implemented.

As this was for clients and I have 12 that I've implemented, I don't have those costs.

No

Consider EM12c over third party products. This is built to be very transparent to the Oracle database environment. Other's, such as Spotlight, Foglight, etc. are a secondary layer and this is using the ASH/AWR data, which is less impacting to anything in the database.

We use Oracle Enterprise Manager for a lot of services like ERP and PLM. We have different applications that are using the solution.

The solution’s pricing could be improved.

I have been using Oracle Enterprise Manager for more than ten years.

Oracle Enterprise Manager is a stable solution.

I rate Oracle Enterprise Manager a nine out of ten for stability.

Oracle Enterprise Manager is a scalable solution. Around 500 users are using the solution in our organization, and we have plans to increase the usage.

Oracle Enterprise Manager's technical support is good.

Oracle Enterprise Manager's initial setup is easy.

The solution was implemented by Oracle.

I rate Oracle Enterprise Manager’s pricing a five out of ten.

I would recommend Oracle Enterprise Manager to other users.

Overall, I rate Oracle Enterprise Manager an eight out of ten.
