Nasir Niamat - PeerSpot reviewer
DB Consultant at i2c
Has offered a cost-effective option despite frequent technical issues and limited market demand
We find some bugs in IBM Informix. Maybe we are using it more aggressively than others. Every month or every second month, we find some bugs in it, which is not ideal. It should be rare, not this frequent. The good thing is they cover those bugs in the next release within weeks or days on demand. IBM Informix should become hybrid and should include AI features similar to other DBMS systems such as Snowflake, Redshift, and DataBricks. This would help its value rise with the market.
Saikat Nag - PeerSpot reviewer
Oracle Application Database Administrator at RP Sanjiv Goenka Group
Manages extensive utility billing applications efficiently with trusted performance and robust support
Currently, I have a very good experience with Oracle Multitenant. The pluggable database is easy to handle and manage, sharing resources efficiently. However, Oracle license pricing is an issue due to its high cost. Our organization is compelled to reduce CPU usage by seventy CPUs because the Oracle license cost depends on it.

Quotes from Members

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

Pros

"It is very easy to install IBM Informix, very easy to scale, and support is quite better."
"My advice is to take it; you will never regret it."
"The most valuable feature is concurrency and locking because my customers usually use databases in OLTP mode. So, for a large number of competitive users. Other features that are well valued are quick large-scale data types. It is better than Oracle."
"The stability is incredible. I have customers with uptimes of several years."
"Not looking at Informix would really mean a shot in your own leg before walking a long distance."
"The scalability is very good."
"OLTP processing capacity and the availability of information with high availability implementation have been significantly improved."
"Replication, all levels of replication, query charting, and the MongoDB embedded are the most valuable features of this solution."
"The feature that I like on Multitenant is the ease - it is very easy for my team to run the database."
"We can then share resources like control files, memory, etc. This lets you stop and start each application without impacting the others."
"The most valuable features are the speed and ease of use."
"The best thing about Oracle Multitenant is its ability to consolidate multiple databases into one engine."
"Oracle Multitenant reduces operational costs because it licenses the root container for multiple databases, costing less than traditional non-CDB databases, which results in financial savings for the company."
"The plug/unplug is the great feature, that doesn't even need the Multitenant option."
"The ability to create multiple databases without using any additional memory and CPU, and reallocating resources among these databases as needed, dynamically, without restarting."
"I would rate the scalability a ten out of ten. Our clients are mostly medium and enterprise businesses."
 

Cons

"The solution really doesn't add new features very often."
"This product could be made easier to use for beginners."
"I experienced poor input/output (IO) performance."
"The solution really doesn't add new features very often. Other solutions are much more actively pushing out upgrades and improvements."
"There should be more intelligence surrounding discovering data to be able to automatically create indexes."
"The solution should offer replication. It would be helpful if the solution would allow us to access third-party tools."
"The solution lacks some functionality."
"Informix is very sturdy, but the problem for us is the marketing action around Informix."
"The main area for improvement is regarding backup and recovery. Today, it’s difficult to set a pluggable database to a former point in time because flashback pluggable database doesn’t exist."
"Oracle Support is relatively unprepared for this. It has improved, but it still has a lot of room for improvement."
"It would be beneficial to include this solution with Oracle Enterprise, but Oracle charges additional fees for it."
"While the product is overall excellent, it is quite expensive."
"The solution is partially extendable. It is not very easy to scale. If we want to grow, we need additional servers, which is why we are considering the cloud."
"Oracle has a lot of work to do with Multitenant because it's a new feature."
"It can be complicated to scale up the solution, but it's scalable."
"Technical support could be faster."
 

Pricing and Cost Advice

"For me, it's always too expensive."
"The product has reasonable pricing. We purchase its yearly license."
"The free edition can be enough to handle moderate-size implementations, but you may want a pay for edition to benefit from more functionality, such as replication."
"I am not aware of the licensing costs or terms."
"This solution is a little bit pricey."
"The price is worth the quality."
"For me, I will go with it if I have the budget. Some features are nicer than before, but at the end of the day, you always have a limited budget. I prefer to upgrade and get a specific hardware when possible. At the end, you will have to make a compromise. You will not get everything you would have liked to have."
