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.

Has successfully supported tenant data separation and enabled strong analytics capabilities
We use VPD, Virtual Private Database, for the multitenancy. We are selling products and using Oracle Multitenant for tenants, for building the product for our customers. We have many customers, actually thousands, and the main objective is to separate data from one customer to another The…

Quotes from Members

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

Pros

"Informix can support huge quantities of data with less memory and less capacity."
"Replication is a valuable feature and easy to use."
"The initial setup is pretty easy."
"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."
"Every version is faster than the previous."
"The solution is quite stable and reliable; we use it mainly due to its general stable nature."
"Not looking at Informix would really mean a shot in your own leg before walking a long distance."
"It is very easy to install IBM Informix, very easy to scale, and support is quite better."
"There are only benefits to using this solution."
"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."
"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."
"The ability to create multiple databases without using any additional memory and CPU, and reallocating resources among these databases as needed, dynamically, without restarting."
"In the past it would take about five hours for us, on a weekly basis, to clone one database or one environment, and now it takes less than two hours, saving a lot of time over the weekends."
"The feature that I like on Multitenant is the ease - it is very easy for my team to run the database."
"The best thing about Oracle Multitenant is its ability to consolidate multiple databases into one engine."
 

Cons

"The product needs a lot more marketing involvement from IBM."
"The solution doesn't include functionality like data anonymization."
"It would be helpful to have IBM salespeople know that Informix exists, and sell it. Currently, it is completely ignored by IBM."
"I experienced poor input/output (IO) performance."
"I would like to see backups from secondary servers."
"The support team could include local engineers to establish efficient communication. It will help us speed up the escalation process."
"The pricing is a bit expensive."
"The solution lacks some functionality."
"That said, Oracle in general doesn't invest in their UI for any of their applications. If we're talking about the dashboard or other user experience, there is room for improvement. I'm talking about on premises. The cloud version has started to improve."
"The solution lacks a GUI for commands."
"I would rate technical support at Oracle a three out of five. They're good, but not good always."
"Stability and full feature coverage will come with future release."
"It needs to have some more granular control over IO resource allocation."
"This solution is a bit complicated when collecting from containers - that feature should be a bit better."
"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."
"It can be complicated to scale up the solution, but it's scalable."
 

Pricing and Cost Advice

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