Chose Oracle Coherence
Oracle Coherence is more straightforward to deploy than IBM Datapower ExtremeScale. We used ExtremeScale previously in the form of their Datapower caching appliances. The firmware was difficult to upgrade in the appliances, and we had trouble getting them patched …
Coherence kicks Redis's butt when it comes to performance and feature set. However, it lags far behind in terms of market penetration and cloud readiness.
I did not get involved with selecting Oracle Coherence. It was already implemented when I joined the team. As I mentioned, Ehcache is probably the most well-known competitor and it is an open source application. If I were to build a new application now, I would think first …
DataSynapse GridServer has the same cache functionality connected with a grid distributed application deployment platform. It provides all the necessary tools to configure and manage these applications.
On the otherhand Oracle Coherence has more a flexible configuration and …
Datadog is good at collecting metrics, monitoring, and alerting; whereas, with Oracle Enterprise Manager, in addition to all that, we can manage the infrastructure as well as automate certain fixes.
Foglight is great, but expensive. It has great monitoring like OEM, but can negatively impact database performance. OEM is better than Foglight because it is a native application from OEM and has features that Foglight doesn't have.
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 …
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).
OEM is better at monitoring applications, while SolarWinds is better at monitoring the underlying infrastructure such as networks, switches, and routers.
I am using Nagios Enterprise monitoring tool also, but as compared to Nagios, Oracle Enterprise Manager is best for our company. Nagios is very weak in some aspects.
Have not tried via Oracle Enterprise Manager, but CommVault is used by corporate for all backups of storage. However, it is just using Ansible to kick off RMAN jobs.
Toad for Oracle is more suited for individual users who have a strong focus on database development, and it is not as comprehensive as Oracle Enterprise Manager. While it is quite decent in logical database layer tasks, such as schema objects and SQL, it lacks visibility into …
OEM Cloud Control base version is free to use if you have licensed Enterprise Edition of one of the Oracle Product. It's sophisticated single point of control, we have used other monitoring products such as Veeam but none of the products have all the features packed together …
Since OEM Cloud Control comes free with Enterprise Edition, we have mostly worked on OEM Cloud Control. I did have my fair share of experience with DBArtisan. It's good and lighter than OEM Cloud Control. It sort of removes your need to even go to SQLPLUS command line most of …
It is much simpler to install and configure as compared to Spotlight and Solarwinds. Oracle Enterprise Manager measures performance diagnostics accurately and raises alerts and takes preventive actions. Other products can not take preventive actions even if they raise alerts. It …
Oracle Enterprise Manager suited our requirement as the clients were using multiple products of Oracle. They were using several instance of oracle implemented at different geographical locations each in Europe, UK, Canada, and USA. So Oracle Enterprise Manager was best fit for …
We have not used any other products to monitor and/or manage our oracle instances. We have always used Enterprise Manager, although we did use a previous version (11g Grid Control), right around the time I arrived at my position. I upgraded to 12c Cloud Control with the …
SQL Developer DBA module allows user, space management, SQL Tuning, ad-hoc queries, and schema management. Great free product supported and enhanced from Oracle.
Oracle Enterprise Manager is easy to install, use and extend the capability of. It supports many Oracle products, which is what it is used for in my company. We selected OEM for its ease of use, intuitiveness and robustness.
It literally all boils down to the budget a team has. Nowadays, even investment banks look for every opportunity to cut cost. Oracle Coherence is a pretty robust and highly configurable cache application that every team should use if they can afford. If they can't, then open source code is their answer.
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.
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.
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.
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.
Oracle Coherence support team is responsive and knowledgeable. We contacted them to ask a couple of design questions about how we were setting up Oracle Coherence based on how we used IBM's Datapower Extreme Scale. They were able to guide us so that we got the design correct the first time and didn't have to go back and re-architect our design later.
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.
Coherence kicks Redis's butt when it comes to performance and feature set. However, it lags far behind in terms of market penetration and cloud readiness.
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.
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.
