Oracle Enterprise Manager Reviews

For us, the most valuable feature is really the ability to monitor. We're using Enterprise Manager to monitor our database infrastructure. Whenever we create a database, we'll apply those templates, and it will monitor. Database will send alerts and create instances that will allow our team to be both reactive and proactive and use some of the warnings that it brings us. We're using it a lot for that -- the ability to do performance tuning, using the OEM, the ability to create different reporting, the ability to be able to get some suggestions from the OEM, in terms of the database performance.

The tool also gives us the ability to create reports for a set of databases, or a set of applications, such that we can create a daily report, weekly report, monthly report, whatever you want, to know about the performance utilization of that group of databases or specific databases.

That's really the key advantage of Enterprise Manager. Although we're using it for Database, the tool has enhancements to provide benefits to an entire IT shop in terms of monitoring and managing the entire IT infrastructure.

As with any organization, before we embark on anything, we have to look at the ROI as well as the ability of a particular tool. Enterprise Manager gives us a tool that's fast and reliable for monitoring and managing our whole IT infrastructure. We're a mutual fund company, so speed is really key in providing satisfactory customer service. The performance and functionality of Enterprise Manager has been huge for us.

The latest release, 13c, which I think came out in December, has additional enhancements in the areas of security, management, creation of users, and different level of functionality. It's much better than before, which was very limited and the majority of users created with the tool were forced to have more privilege than they should have. We're currently working on upgrading to 13c, and I'm looking forward to seeing whether that will apply for our environment.

Deployment has been fine. There have been no issues.

With Enterprise Manager, you've got a tool that's providing end-to-end administration and monitoring of your IT infrastructure. The tool, therefore, has to have a very smooth way to configuring so that it is highly available. This, of course, plays a very important role in functionality because you don't want the tool to be a single point of failure.

So Oracle has claimed that they've enhanced that part of Enterprise Manager. For me, that's important because as a data architect, I play a lot of roles and I've been able to configure the tool to have four nines of High Availability. If you have a tool that you depend on for monitoring and administrating your entire IT infrastructure, the last thing you want is for it to have an level of unavailability.

It's scaled to our needs.

We have premier support from Oracle, so we have a very good relationship with technical support.

Right now, the only complexity is setting up our environment for High Availability so that we can scale it and have it highly available not just within the same data center but spanning to multiple, different locations. That's the only tricky part because it involves additional products from other companies, like Cisco and F5. So for us, setting up a standalone, vanilla Oracle Enterprise Manager is a very, very small part. It's because we have to set up the large, diverse environment with maximum-availability architecture that it's been a challenge for us.

One piece of advice is just why, if you don’t have Oracle Enterprise Manager, you aren't taking advantage of it. I assume your DBA's might be spending extra hours and off hours, and if you set up and deploy Enterprise Manager the right way, you will see at least a 50% decrease in unnecessary, mundane work.

Enterprise Manager is a centralized system. It will help integrate all the Oracle servers and Oracle applications into a central single dashboard that we can see, and it helps to monitor and control all the services from enterprise management.

The single-pane and single interface in the centralized system is the most valuable feature. All the enterprise services can be seen from a single pane, whether it be a database, applications, or hardware. We can manage and monitor from a single page.

Lots of other OEMs we can integrate, but there are very few variants that we can bind and see and monitor from OEM Enterprise Manager. In that case, Oracle can increase the addition of other OEM devices that we can integrate into enterprise management.

There are limited numbers of other OEM devices that can be integrated into enterprise management that can be scaled by Oracle by adding other OEM devices to enterprise management.

I have been working with this solution for more than five years. 

It is a stable solution. I would rate the stability a ten out of ten. 

It is a scalable solution. I would rate the scalability a ten out of ten.

All the clients that have Oracle servers are using the Enterprise Manager. So, there are around six to seven clients using this solution.

The customer service and support was very good.

Positive

I would rate my experience with the initial setup an eight out of ten, with one being difficult and ten being easy. 

The deployment process takes five to six hours. 

The process will take the deployment of our database first. We need to set up the Oracle database. After that, the database is created, and we need to create a listener. And after that, we can set up the Oracle Enterprise Manager database. In the middleware, it will communicate with the database, and after the process is complete, we can browse the Oracle Enterprise Manager. With the help of Oracle Enterprise Manager, we can communicate with all the servers and other posts that support SNMP or with whichever supports the Oracle Enterprise Manager point.

It's a very stable monitoring tool that can help manage all the resources and view all the resources from a single dashboard.

Overall, I would rate the solution a nine out of ten. I deducted one point because it doesn't offer a feature of allowing other operating systems to be hosted on Spark.

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.

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.

We use the solution for data encryption.

The solution is easy to use and has good performance.

The tool is expensive. 

I have been using Oracle Enterprise Manager for ten years. 

I rate the solution’s stability a nine out of ten.

The solution is scalable. The solution’s scalability depends on how you manage your hardware, server type, storage and the processes needed.

We have 200,000 users using the solution. We have sufficient usage of the solution.

The initial setup of the solution is straightforward. The time of deployment depends on the database and customer. The solution needs a third-party integration that uses the database.

Deployment is the same with the wireless license. You first deployed a server to the cloud and then created a schema for all your data links. The deployment process depends on the system type you will implement.

The solution’s licence is expensive. It is a user-based solution and has a yearly subscription for upgrades.

The maintenance of the Oracle Enterprise Manager solution depends on the type of banking system you are using, the number of users, the amount of data, and whether or not you have migrated any data. Since we have not migrated any data, it is going as it is.

You should go for an open-source solution if possible.

Overall, I rate the solution a seven out of ten.

It's a good product for Oracle management and monitoring. This solution is deployed on-premises, and we are using the latest version.

The most valuable feature is the monitoring because it's very useful for checking and troubleshooting compared with other products, like Nagios for example, that have some interaction with Oracle. Enterprise Manager is good for a DB administrator to troubleshoot and check monitoring.

The interface could be more friendly for basic users.

I have been using this solution for one year. 

I haven't used Oracle technical support for this product. But we have used them for other products, like Oracle Server or Oracle Appliance, for example. For Oracle Appliance, I don't have good feedback because recently we had some issues with Exadata, and they were taking too much time with giving us a solution, so the case was still open for weeks.

Technical support is responsive, but the problem is that there are some other customers that we are managing, and there is not good feedback because every now and then, there are issues for which we open a case, and the same issues are continuously appearing. We are experiencing issues with the same hardware, and we never get a fix.

This is for Oracle Private Cloud Appliance and for Oracle Exadata. For Oracle software, we have good feedback about the quality of the support. But as far as the hardware, I cannot say the same.

Setup wasn't very complex, but usually Oracle products are not easy to install. It's normal for there to be some complexity because Oracle products are not "plug and play" like other products.

For monitoring issues, I compared Oracle Enterprise Manager to Nagios. There was a monitoring need that Nagios could not provide but Enterprise Manager could.

I would rate this solution 8 out of 10.

I work on whatever development projects I get with Oracle Enterprise Manager in my company.

The most valuable feature of the solution is that it is a very user-friendly tool. I find Oracle Enterprise Manager to be a complete tool because it has options like SQL Scratchpad, Oracle Migration Workbench, etc.

Oracle Enterprise Manager's scalability is an area with certain shortcomings where improvements are required.

In the future releases of Oracle Enterprise Manager, I would like to see the product offer the ability to its users to scale up the solution whenever required.

I have been using Oracle Enterprise Manager for around ten years. I work as an Oracle consultant.

It is a stable solution.

Though Oracle Enterprise Manager is a scalable product, it may not be as scalable as Oracle Big Data. You can scale up Oracle Big Data to any number, but it may be difficult to do so when it comes to Oracle Enterprise Manager.

Around 10 to 50 people in my company use Oracle Enterprise Manager.

The solution's technical support is good. I rate the technical support a nine out of ten.

Positive

The initial setup of the product is easy.

The product's installation phase may take up to a maximum of 30 minutes.

The product's installation phase can be taken care of by one person.

The solution is deployed on an on-premises model.

Usually, I use Oracle Enterprise Manager for development purposes, and I can say that the development part is very easy with Oracle.

I rate the overall tool a nine out of ten.

This is a very good Oracle tool which enables us to incorporate all the databases throughout our environment, set up several rules and even monitor from there. We can perform a lot of operations. If you have small databases you can plug into the OEM, and you can perform any sort of operation with one click of a button. That makes it more convenient and makes life easier than logging into each database separately.

You can set the rules so that every time you have several maintenance activities you don't need to go to each database and do the same work again and again. Instead you can create jobs in the OEM and you can also create groups, like production, development, performance and environment. All these environments you can club together so that you can perform several operations based on environment-specific criteria.

When you need to perform activities like purging and archiving, this can be done easily and you can even do backups which is a tedious activity. If you have the right description monitor, just click on the buttons in the OEM so that you can fire up the backups everyday at a specific time. It can even alert us by email if by any chance the backup fails and you can just log in to a particular mission and check why it failed.

It's a very easy way of maintaining all the databases instead of wasting time on the regular day to day tasks. You can use your time productively, instead of investing time on these mundane tasks. That way it helps us a lot.

It could improve in some areas like the screen. It's not so clear for the novice, when a new person looks at the screen he/she may not really understand where to start first. They could make that process a little easier, so that even a novice who starts using it can at least have the basic idea what to do.

We've been using the product for almost six years.

It is stable of course, it's from Oracle.

It's scalable depending on the way you build it. From the base configuration itself the server capacity and the installation, you have a number of targets, say 0-10, 10-250, 250-1000. Based on your company's requirement you have to install and configure those so that it will be scalable throughout that time period. You will also require enough memory, CPU cards for supporting those targets.

I would rate the support as 8/10. Once they start responding on the tickets, they'll definitely take you to the solution.

I would recommend it. There are a lot of people who like to write scripts and stuff. If they are comfortable writing scripts then definitely they could use it. But many things can be done which cannot be done through scripting. I would recommend you give it a try. Definitely once you give it a try you will like using it.
