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

"This solution has made financial reporting possible by allowing financial people the opportunity to set Informix to "Auto Pilot" so that they can attend other duties."
"The scalability is very good."
"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."
"It supports in-house-built applications in .NET and VB6"
"My advice is to take it; you will never regret it."
"Replication, all levels of replication, query charting, and the MongoDB embedded are the most valuable features of this solution."
"The solution is quite stable and reliable; we use it mainly due to its general stable nature."
"Informix can support huge quantities of data with less memory and less capacity."
"Oracle is a more automated database."
"It's a really great new option for Database 12c, with huge potential because it allows a container database to hold many pluggable databases."
"Multitenant has a container database with many pluggable databases."
"The ability to create multiple databases without using any additional memory and CPU, and reallocating resources among these databases as needed, dynamically, without restarting."
"As far as this product is concerned, we are happy with this product."
"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."
"I would rate the scalability a ten out of ten. Our clients are mostly medium and enterprise businesses."
"I have used it for various clients and it's been working like a breeze."
 

Cons

"The technical support services need substantial improvement."
"It would be helpful to have IBM salespeople know that Informix exists, and sell it. Currently, it is completely ignored by IBM."
"The solution should offer replication. It would be helpful if the solution would allow us to access third-party tools."
"Continue extending the SQL language for compatibility with the competition's language, including Stored Procedure Language."
"This product could be made easier to use for beginners."
"The product needs a lot more marketing involvement from IBM."
"This solution is in need of more current tools."
"For me, it's always too expensive. The problem is that Informix sometimes competes with free products, so yes, it's very expensive, but when we're talking about licensed products like SQL Server or anything, the midsize pricing could be significantly improved."
"Oracle has a lot of work to do with Multitenant because it's a new feature."
"There are many functions where changes are not easy to implement, and we try to avoid modifying these areas due to security issues and the complexity of maintaining them."
"While the product is overall excellent, it is quite expensive."
"Oracle Support is relatively unprepared for this. It has improved, but it still has a lot of room for improvement."
"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."
"Oracle is too complex. Anyone that has experience with Oracle knows that their product design or idea may be very good, but when you go to work it will take you hours because it is very complex."
"It needs to have some more granular control over IO resource allocation."
"The only issue is that shared files for the main container affect all container databases if something happens to them."
 

Pricing and Cost Advice

"For me, it's always too expensive."
"The product has reasonable pricing. We purchase its yearly license."
"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."
"This solution is a little bit pricey."
"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."
