DBArtisan is excellent for large institutions with multiple mission-critical databases. It works especially well for cross-platforms RDBMS support. I am mostly familiar with Oracle, but less familiar with SQL Server and Sybase. So I certainly appreciate having a similar interface that allows me to manage those less familiar RDBMS, as this will mean a smaller learning curve. DBArtisan is mostly for DBAs, it is not suitable for developers, I believe the vendor has a separate tool for that
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.
DBArtisan lacks a utility that does schema or object comparisons, which is a feature in Toad. I find this useful in some situations where I need to find out all differences between Prod and QA for a given schema, for example. DBArtisan doesn't seem to have the capacity to do this.
I wish there was a way for the tool to warn me before performing a long-running task. For example if I want to re-organize a large table or rebuild an index for a table with millions of rows, it should warn me before executing it, so that I may choose to do it in a different way. Sometimes if I let these long operations run for too long, it freezes the program and crashes DBArtisan. I would rather run it on the DB server, and run it in background so that it doesn't time out, if DBArtisan gave me a warning before execution.
Idera has taken over Embarcadero. I never heard of or dealt with Idera for support. I don't know if they have same the quality support as before.
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.
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.
