Offers effective monitoring of resources but lacks the ability to connect to an AWS instance and write custom queries.
We use it mainly for monitoring, including CPU, memory, and disk space, and for troubleshooting purposes We've set up alerts to notify us when performance deviates from the baseline we've configured for each resource. So, whenever that happens, we get an alert and can investigate immediately. So,…

Facilitating real-time business insights with enhanced data querying
Coherence is beneficial due to its multi-indexing to the same object and filtering based on data attributes within the object, followed by aggregation. These features facilitate querying data with multiple keys rather than just a single key. Its real-time data processing capabilities provide insights for business decisions with up-to-date information.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"We're able to diagnose issues prior to their actually becoming issues. Without the alerting, we wouldn't have a clue as to what was going to happen. With the alerting, it gives us a heads-up that a specific threshold has been met, and we need to take specific action."
"The ability to go back and look at historical data is the most valuable feature."
"Ability to identify bottlenecks, deadlocks and slow running queries and run monthly and daily reports."
"One of the things that it is used for is to detect anything that could possibly cause our systems not to function well, and it has helped us to determine that before anything has actually happened."
"Baselining our SQL Servers has made a huge impact."
"The most valuable features are disk space projections for planning, and also the Snapshotting ability, to look back in time, to see what was going on the server at a particular time. It's basically the output of an sp_who2."
"There are several monitoring tools, but IDERA SQL Diagnostic Manager is actually better than other competitors."
"The best part of SQL DM is the ability to customize alerts and counters. This allows our team to find an issue then alert on the issue at a granular level."
"Basically reducing response times to extremely small latencies in their apps."
"A single logical cache scattered across various geographies ensured we had only one cache to look against (location transparency) at the same time, ensuring high availability."
"Coherence has helped us to drastically reduce the request time of our web applications."
"We are storing information from one of our applications; this allows us to answer requests in milliseconds, while the application would take seconds to answer requests from clients."
"The product is great, simple, and easy to use and integrate."
"Technical support from Oracle is okay."
"It was suited for stock exchange marketing software, improved performance."
"Oracle Coherence is a very good product which helps to create internet-scale applications using a high-performance grid."
 

Cons

"They can improve checking the status of the CPU, memory, and IO utilization from each task."
"Reporting and overall analysis of data gathered from SQL Server."
"I'm going to do an upgrade which may resolve my issues, but one area for improvement is its ability to handle the amount of data that we collect with it. We're likely one of the largest installations, with over 300 servers being collected with this product, and sometimes there are gaps. That would really be my only concern, in terms of how the data is collected and stored, for consistency."
"Some more granularity in alerting."
"Tech support has been okay, not that great, but they made sure that we got what we were looking for."
"We don't find that it helps us with performance monitoring and diagnostics. We find that SentryOne does that better. Also, in terms of alerts, we had to customize them dramatically so that we didn't get alerted on every little thing."
"One thing I'd like to see is the ability to view the execution plan and have the system automatically recommend potential query optimizations, especially at the query level."
"With basic SQL training in my history, I've found at times I needed to Google SQL counters, for example, to understand what was occurring or how to configure SQL DM to be useful."
"The price is high. I believe there should be a cheaper version for only the caching solution."
"This platform has issues with stability and performance."
"Configuration is too complex."
"It is very expensive. It might not work well for small business people."
"Complexity being a huge contributor to risk/cost for projects, I am more likely to use other products as a result."
"Customer service: Five out of 10."
"OSB could be tuned to do things like Apigee."
"Price is very high - as for any Oracle product."
 

Pricing and Cost Advice

"We were upgraded to Premium Support without their actually asking us, when we were quoted. Then I asked for Standard Support and that they had to re-quote us that. But they don't do that by default. They upcharge you by default, which I didn't think was very nice, without even asking."
"The pricing is reasonable, it's comparable with the competitors."
