To drive scale and predictable results, Oracle’s integrated functionality and automation for DevOps monitoring and IT operations management aims to make it 50% easier to prevent and solve IT problems.
OEM is very well suited for all Oracle products, especially Oracle databases and Exadata machines; even not Oracle hardware, it is very good and displaying high level details. OEM is not well suited for older hardware vendors like AIX, HP-UX, DEC/Digital, Microsoft (sql server). This is a big negative as most large companies have a heterogeneous environment with many different vendor hardware and (database) software products.
Ideal for a complex organization with requirements to build very complex reports. Especially useful for organizations that already have numerous Oracle products and need to pull information from them. This tool works best when plugged in with other Oracle tools and databases. If you're a larger company, and/or if you're managing a lot of data, Oracle IT Analytics Cloud Service is the perfect tool to manage your Oracle deployment. It provides a number of different options for intelligent analysis while not being too overwhelming to manage. Companies that want a robust tool to manage all data and present it in a visually appealing way to users will greatly benefit from this tool. The tool is very customizable and can be tailored to meet the needs of different users.
Monitoring Templates: There are out of box monitoring templates for each target types, you can customize them or use them as it is.
Administrative Groups: This is a relatively new feature in OEM Cloud Control. This lets you create and manage your targets and monitoring templates smarter and with less re-work.
DB Monitoring: There are so many cool DB monitoring features and visual graphics, that it can be used by both DBA and functional people to see what's going on in the database.
Bugs. Every version we upgrade to has a number of bugs. Some stop us from rolling to production OEM (we have a sandbox OEM), some are simply annoying. If I could improve on one thing, it would be for better QA from oracle before releasing each version.
Flash. I'm told that they are moving from Flash to Jet in version 13.3 and beyond (we are on 13.2 currently). That change cannot come soon enough. The OEM pages load SO slowly due to Flash.
Hierarchy Groups. OEM allows five Hierarchy groups. A Hierarchy group allows a top down metric/rule roll out. However, they limit you to five. I'd like to see them open that up, so that we can have any number of custom groups.
There's a pretty steep learning curve that needs to be overcome in order to properly deploy this tool. So, unless you're a seasoned IT administrator, you may have a fair amount of homework to do. Implementation and maintenance of this takes a bucket of consulting hours from outside consultants to come in and set up the tool and regularly maintain it, in the long run, this could be costly.
The dashboard is not as easy to set up as I would like, however, after setup it will serve your purpose in the best possible way. You may not be able to find out how some data related to another and you can create a report that you think has all the details you need, but it comes up blank because the data really is not connected.
There aren't enough self-learning materials available like tutorials and how-to videos. I would like to have access to more e-tutorials from inside the tool. A steep learning curve for most. It would be nice to have a robust learning portal within the application where users can access self-learning material directly from the application and step to spet guides on how to perform different tasks.
Does not provide the ease of adding additional data sources without lots of complications. Even though it can handle large data sets, rendering of reports can take a fairly long time if the parameter set is large. For some time it seems like processing takes a bit of time when large data sets are being used. This is not the case with other competing tools.
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.
The product management team is very responsive. They are on LinkedIn and Twitter, responding to your questions and offering ideas. I have not opened an Oracle support ticket for this product yet
Being an Oracle shop using Oracle Database and MySQL, management console from Oracle was a better choice than IBM or Microsoft even though we do use Microsoft Azure and storage/servers from IBM (on-prem).
Oracle Analytics Cloud is an enterprise solution and can't be compared apple-to-apple with a data visualization tool like Tableau. This is not the same use at all. Before selecting Oracle Analytics Cloud, it is most important to consider the data you are looking to collect and how you plan to visualize it. Other tools like Tableau and microstrategy feel smoother to work with, have better UI's and are quicker when processing data. It is also important to think through how you will use the data across your organizations. Can have a steep learning curve but once you are well trained on this tool, the possibilities are endless. The tool is highly customizable and will generate what you design it to generate. If you are having issues with reports and analytics, it is most likely due to data quality issues. Oracle Analytics Cloud also benefits by adding Essbase in it, to perform multi-dimensional analytics.
We are a 7x24 shop. Oracle Enterprise Manager Cloud Control helps us meet that objective by proactively warning us before issues cause down time. Things like disk space, archive log issues or temporary table space issues.
Spreading the use of this tool outside of the DBA group has allowed us to not hire additional personnel for those teams. Over time, as folks have retired from our operations team, we are not replacing them. Instead we have used OEM Cloud Control to automate tasks.
We also now have the tools to measure up-time by using specific measurements inside of OEM. This allows us to report real numbers to management.
