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

"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."
"Monitors and alerts on our mission critical instances in real-time on a 24/7 basis."
"Memory and CPU utilization features are good."
"SQL monitoring time has been dramatically reduced and our IT Infrastructure team has improved SQL maintenance and monitoring knowledge over time just by using SQL DM."
"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."
"SQL DM made troubleshooting much easier and allowed multiple people to look into an issue with confidence."
"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."
"Coherence absolutely outperforms others in terms of scalability, reliability, and performance."
"Coherence allows linear on-line scalability across multiple commodity servers."
"Portable object format (POF serialization) allows objects to be serialized and deserialized between Java and .NET so the two platforms can exchange data seamlessly."
"Since we implemented Coherence, this data is in memory all the time; so the results are found in milliseconds instead of five seconds."
"Introducing a data grid, we moved from a vertically scalable solution to full scalability."
"It can handle an extremely high volume of data."
"Oracle Coherence improved site performance and the customer experience."
"Coherence has improved response times for queries of sizeable data sets, and by allowing for data distribution and replication through clustering, it improves the reliability of information systems."
 

Cons

"It would helpful if SQL DM could mark when changes are made within the program."
"Some more granularity in alerting."
"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."
"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."
"They can improve checking the status of the CPU, memory, and IO utilization from each task."
"The initial setup gives too many user rights to the server, so you have to put a user that is part administrator's group - that's the preferred way - on each server, which is kind of a risk. You want to do least privilege and you're not doing that."
"Scalability is what I mentioned earlier, regarding room for improvement. It doesn't seem to scale out to an environment as large as ours, with just a single monitoring server."
"I would absolutely love to create customized dashboards but, unfortunately, they don't provide me the information that I need to create the report. The report I need is the detail or the transaction detail that's happening on those Snapshots. I'd like to be able to go back through time and search for things. I don't have that functionality, which is very disappointing. That's pretty bad and frustrating because I could query it and find out so much information about what's hitting my environment and when, but instead, they want control over it and to not give me that information. So it's encrypted. I can't pull it out and that is really bothersome."
"Cluster management tools that are independent of WebLogic. Dynamic cluster config rollout and rollback."
"Monitoring API needs to be improved and needs to be user friendly. Also, the error and exception handling is not that great as it can be difficult to debug issues."
"Technical support is 3 or even 2 out of 10. Working directly through an account rep or a contact on Coherence dev team helps a lot."
"Oracle Coherence has considerable operational risks."
"The initial setup is complex and time-consuming."
"The price is high. I believe there should be a cheaper version for only the caching solution."
"Would be good if the initial setup was easier."
"It has become very heavy along with the price for Oracle's integrated product as a fusion middleware."
 

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."
