Oracle Enterprise Manager Reviews

Using this product makes our integration process more easy and seamless. Previously, it used to be hard for a few applications. Now with this product, we can easily define our RES service or sub-service and can have multiple platforms hitting the service.

We have a dedicated security layer and use this as a security layer.

In my opinion, this product needs to improve its performance.

We need to have more detailed monitoring when certain services extend beyond a particular time frame. For example, if it goes beyond 60 seconds, we want to get an alert saying something is wrong. Anything that can self-optimize itself would be a great feature. For instance you put an SQL and if this tool can give us a recommendation stating that this SQL doesn't seem to be optimized and so you may run into issues for this feature. Thus, a self-optimization feature would be good.

I have used this product for almost 5 to 6 years.

This is a stable product.

We have experienced some downtime in terms of performance. For example, when we carry out some complicated code, it usually times out; sometimes it goes beyond sixty seconds and that's frustrating for the users.

Right now we don't have it on the cloud platform yet, but once we do most probably we will be able to run as many instances as we can. Currently, we are running it on twelve instances on our own private infrastructure. I think moving onto cloud would give us more flexibility.

Oracle provides good support and we find them very responsive. We tend to use them a lot because we don't have strong expertise in this area. We go ask them questions such as how do we do this, do you have any clients who are already using this kind of feature or do you have any extra plugins for this new feature and they are very supportive.

I would recommend this product to others. One of the things with Oracle is that they are expensive. They have to cut down their costs so that a smaller organization can easily adapt to these features. Although those who have an enterprise platform and wouldn’t mind spending the money on this product, should go for it.

In my opinion, without Enterprise Manager no DBA can do their job. There are better tools out there, but they only complement OEM because it may not do the whole job. OEM, though, is very intuitive when it comes to performance tuning, metrics, and monitoring.

Without it, it's like driving a car without seeing with your eyes. Without OEM, I can't troubleshoot any of the issues that arise. For the Automatic Database Diagnostic Monitor, port reports, memory advisors depending on load, manual memory management and other database analyses that SGAs and PGAs expect -- these are all things that can only be provided by OEM.

It's quite user-friendly when integrating, but when propagating user access and agents, it's not so intuitive. I'm using 12.1.0.3, I believe, and there seems to be a log of bugs that haven't been worked out.

The issues with deployment in 12.1.0.3 have to do with user access and agents. Other than that, it deploys fine.

It is buggy in certain process, but every Oracle product has bugs, although unless you really hit it you would never really come to know about it. For example, one of the Java processes within OEM chews up the entire CPU. This is an obvious bug, but there is a patch that can be applied to correct the issue.

It scales with out issues for us.

Deploying agent is not easy, but the rest of setting up is fairly easy.

We implemented it ourselves with our in-house team.

You need OEM if you are having Oracle databases. OEM is very expensive, but it does some nice things like memory advisors and ADDM reports. There are products that complement OEM, but they can't replace it.

We use Enterprise Manager for databases.

We haven't used Enterprise Manager for very long. We mostly work with another solution.

I rate Oracle Enterprise Manager eight out of 10 for stability.

I rate Oracle Enterprise Manager eight out of 10 for scalability.

Installing Enterprise Manager is complex. The time needed to deploy it varies depending on the environment. 

I rate Oracle Enterprise Manager six out of 10 for affordability. It's expensive. 

I rate Oracle Enterprise Manager seven out of 10 overall.

We are using Oracle Enterprise Manager for managing databases in banking.

Oracle Enterprise Manager has helped our organization by allowing us easy access to data in the extractor manager.

The most valuable features of Oracle Enterprise Manager are the data guide and online monitoring.

Oracle Enterprise Manager could improve the monitoring types and the graphics.

I have been using Oracle Enterprise Manager for approximately six years.

Oracle Enterprise Manager is stable.

I have found Oracle Enterprise Manager to scalable. We are using a lot of data in our large data warehouse. We plan to increase usage and upgrade in the next two or three years. For the next upgrade, we will most likely move to the cloud.

We were previously using SQL and we switched to Oracle Enterprise Manager because of compatibility issues with our system.

The initial setup of Oracle Enterprise Manager was a bit complex. The whole process took approximately two days.

I rate the setup experience of Oracle Enterprise Manager a four out of five.

We used a specialist to do the implementation. The vendor assists with the maintenance of the solution.

We did evaluate other solutions before choosing Oracle Enterprise Manager.

My advice to others is Oracle Enterprise Manager is a stable and scalable enterprise compared to the other similar solutions.

I rate Oracle Enterprise Manager an eight out of ten.

We use the solution for database repositories. The use cases depend on the applications. We can't use Oracle at the back end if our application does not support Oracle. Our company moved us from Oracle to Microsoft SQL Server. The use cases of sales and distribution are very different from manufacturing.

It is a good solution. It is the best database management system.

The deployment is not straightforward.

I have been using the solution since 1997.

The tool is stable.

The tool is scalable. We have around 700 users. We do not have plans to increase the usage.

We must undergo some training to deploy the product. The time taken for deployment depends on what we are deploying. If it is a green system, it will take a lot of time. If it is a single node, it will take less. The configuration is different.

We work mostly with partners.

The product is very expensive.

I would not recommend the solution because of its price. Otherwise, it is good. Overall, I rate the product a nine out of ten.

We use Oracle Enterprise Manager Cloud Control to monitor and manage our Oracle and MySQL databases.

The Oracle Databases are key components of our company. All of our services rely on critical customer data and transactions. We need %99.9995 uptime, and Oracle Enterprise Manager helps us to achieve this goal with its superior monitoring and management capabilities. Even mid-level administrators can quickly detect and solve performance problems, and our monitoring team can easily follow the general status of our databases and servers.

Oracle Enterprise Manager provides comprehensive monitoring features for all Oracle products. It has an extensible architecture, so it’s possible to add third-party plugins to extend its monitoring abilities. These are valuable features of Oracle Enterprise Manager for all Oracle customers.

On the other hand, I think the most valuable feature of Oracle Enterprise Manager is its management capability for Oracle products. It makes a real difference when comparing it to any other monitoring solution in the market. You can manage your Oracle Databases, Oracle VM, WebLogic, and other products with Oracle Enterprise Manager.

It's better to have native agents specially when monitoring legacy systems. So the agents can consume less resources.

I have not encountered any serious stability issues since version 13c.

I did not encounter any scalability issues, and we know that we can easily scale up our Oracle Enterprise Manager system by adding more application servers, and even using RAC database as its repository.

At the same level as other Oracle products.

I used several monitoring solutions, including open source, both free and proprietary. Most of them are designed to monitor system health and require additional plugins to monitor Oracle databases. Unfortunately, they do not provide the same level of insights when monitoring Oracle products as Oracle Enterprise Manager provides.

It is very straightforward because of its improved installer. Since version 12c, installing Enterprise Manager has been very simple. The installer handles everything even including configuration issues with your database repository and OS kernel parameters.

The basic functions are free. You pay license fees only for advanced features. That means you can buy a license for selected (mission-critical) systems which need extensive care, while you can still use basic monitoring for the rest of your target systems.

I’ve been using this product for years. I evaluated other options from different vendors such as Quest Foglight, CA Unified Infrastructure Management, ManageEngine OpManager, Zabbix, Nagios and maybe some other tools I don’t recall right now.

First, check the compatibility index and be sure that your targets are supported with the version you’re planning to install. I also advise keeping your system up-to-date by installing patches regularly.

I am satisfied with the solution. It enables me to keep a check on my business. It is a good product. We can manage everything in our environment. It is the best solution in the market. I am satisfied with the integrations provided by the product.

We are facing a problem due to the upgrade of TLSv1.2. We cannot access OEM currently. We have to upgrade our server to the latest version to be compatible with the security layer of TLSv1.2.

The solution is not as simple as people say it is. We need to be trained in it. It is supposed to manage the whole infrastructure. Currently, I'm using it to manage only my databases and Oracle applications. Oracle must provide some training courses to use the solution.

When we procure Oracle products, they should include training courses. Oracle is responsible for training the users before installing the software or the hardware. Other products provide training.

I have been using the solution since 2016.

Technical support is not good. We have to go through Oracle FDP. We have problems with support.

Neutral

The solution is free.

I am not using the product to its full capability. Overall, I rate the product an eight out of ten.

I think the neatest, most valuable feature of Enterprise Manager (OEM) is that single pane of glass for the whole stack, that it gives me as an admin the ability to look all the way up from my storage all the way up to the application tier.

There's a lot of benefits to Enterprise Manager. From the monitoring capabilities is that single pane of glass. It's being able to look at an application and then look at the database component. Look at the storage component on it from a monitoring, troubleshooting. Once you understand what the pain point is, you can easily automate it through thresholds and events, where you get notifications or tickets opened when you see a similar behavior. But, It's not just the ability to monitor, it's the ability for actual change. I can use Enterprise Manager to actually install Bare Metal systems. I can use Enterprise Manager for all my database, to deploy new database instances, or deploy WebLogic instances. That's the value is it's that single pane of glass for the whole enterprise.

What I would love to see in Enterprise Manager is more support for the hardware, more support for Bare Metal. Right now I can do Bare Metal deployments with Linux and OVM and that's an awesome capability, but I would love to see more functionality with Solaris. I'd also see more change functionality in Enterprise Manager. It's a great tool for monitoring an ODA, Oracle Database Appliance, but it doesn't let me change the database appliance, as an example.

I have been using 12 and 13 since they came out.

A few, but usually due to errors on my part

Stability on 13c has been fairly good. I haven't had any major issues with 13c where it's panic for no reason and just gone dead or anything like that. In 12, again, didn't really have any major stability issues there of it panicking or blowing up.

Scalability for an Enterprise Management system, it does scale well. Both 12 and 13 scale well for high availability as well as for handling more agents, more targets.

Great, the three times I have needed to open a ticket!

Oracle's tech support for OEM is fairly good. Again, I've been using OEM heavily since 12 was released, I think four years ago now. I've had to open up, I think, three tickets since I've really been using it, so it's been a very low volume of tickets.

Generally, with Enterprise Manager, the question is when do you decide to use it. My thought is if you're running an Oracle product and you want to enterprise great IT, you need to use it from day one.

From just the monitoring and the provisioning, just all the capabilities of it, it saves you a lot of time. It simplifies a lot of the workload you do day-to-day in an IT shop.

Very easy for the initial setup, up and running in afternoon

The initial setup on Enterprise Manager is fairly straightforward. Actually, on my own personal blog, I blog step-by-step - installing the database, installing the OMS, it takes a couple hours, depending on the speed of disc, but it's fairly straightforward.

OEM helps with the license complexity, you can ask it for each page what licenses are needed, and it can also report on all your license consumption

Enterprise Manager, I'd probably rate it a nine and a half. If you're not running it, install it and run it.
