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

"The solution's stability, performance, enhanced functionality, and replication are all great features."
"We don't have any problems with the Informix Database."
"Informix can support huge quantities of data with less memory and less capacity."
"My advice is to take it; you will never regret it."
"The initial setup is pretty easy."
"It supports in-house-built applications in .NET and VB6"
"It supports multiple applications and business intelligence tools."
"The solution is quite stable and reliable; we use it mainly due to its general stable nature."
"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."
"Maintaining databases is a valuable feature for us."
"You can scale the solution as needed."
"The modernization aspect of Oracle Multitenant is significant; it wasn't available previously in database technology, but now it is, enhancing database consolidation."
"It is quite stable. We have not faced any kind of instability in the database."
"The ability to create multiple databases without using any additional memory and CPU, and reallocating resources among these databases as needed, dynamically, without restarting."
"The analytics tool, Oracle Analytics Server (OAS), is the main important component of this solution and in the analytics part, the VPD handles all the necessary functions effectively."
"I would rate the scalability a ten out of ten. Our clients are mostly medium and enterprise businesses."
 

Cons

"The solution should offer replication. It would be helpful if the solution would allow us to access third-party tools."
"There should be more intelligence surrounding discovering data to be able to automatically create indexes."
"The technical support services need substantial improvement."
"Every month or every second month, we find some bugs in it, which is not ideal."
"The pricing is a bit expensive."
"The support team could include local engineers to establish efficient communication. It will help us speed up the escalation process."
"It would be helpful to have IBM salespeople know that Informix exists, and sell it. Currently, it is completely ignored by IBM."
"I really would love to have a QT plugin."
"Oracle Support is relatively unprepared for this. It has improved, but it still has a lot of room for improvement."
"The only issue is that shared files for the main container affect all container databases if something happens to them."
"This solution is a bit complicated when collecting from containers - that feature should be a bit better."
"There is room for improvement in customer service and support."
"Stability and full feature coverage will come with future release."
"It can be complicated to scale up the solution, but it's scalable."
"Even though we say Unplug Plug Upgrade is a very good feature and it does work, we are seeing that sometimes it takes longer than what we expect for larger databases."
"From the scope of improvement, I would say that people are adopting new query options. Certain databases like MongoDB adopt new query options so that they can just pull the data."
 

Pricing and Cost Advice

"I am not aware of the licensing costs or terms."
"The product has reasonable pricing. We purchase its yearly license."
"For me, it's always too expensive."
"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."
"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."
"This solution is a little bit pricey."
"The price is worth the quality."
