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.
Muhammad Usman Muzaffar - PeerSpot reviewer
Senior Vice President IT Operations at ZTBL
Running secure internal banking applications has been reliable and supports fast deployments
I am still working with Oracle products. I am still using Enterprise Manager 14c. I am using Oracle Database, Oracle ExaCC, Oracle EBS, Oracle WebLogic, Oracle Enterprise Manager, and Oracle Linux. I can answer questions about my experience with WebLogic Suite. I use it in my company. I have not used WebLogic's diagnostic tools. I do not utilize its lifecycle management features. I do not have much experience with WebLogic Java EE support, as I just deploy the application and the other team utilizes this server. I am not directly involved in WebLogic. I have been using Oracle Linux myself. The deployment is local, on-premises. I have been working with Enterprise Manager as well. All the components of Oracle I am using are on-premises. I use Oracle 19c database, Oracle ExaCC, Exadata on Cloud at Customer. I have been using Oracle Linux, Enterprise Manager, and databases as well. I have been working with Oracle Database for about 20 years. My experience has been 100% positive with Oracle Database. I have utilized its Real Application Clusters along with Data Guard. I do not use Oracle's Advanced Analytics and machine learning features right now. I have given this review an overall rating of 9 out of 10.

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."
"My advice is to take it; you will never regret it."
"The solution is quite stable and reliable; we use it mainly due to its general stable nature."
"Replication, all levels of replication, query charting, and the MongoDB embedded are the most valuable features of this solution."
"Informix can support huge quantities of data with less memory and less capacity."
"The initial setup is very simple."
"The scalability is very good."
"I think that Oracle today is the most powerful relational database, especially for PCI compliance, high availability, and high performance."
"I have been satisfied with the technical support from Oracle."
"They are ahead of all other database providers, so we are happy and our client base is also very happy with Oracle Databases."
"We plan to continue using the solution in the future."
"It does what I want it to do. It has got a lot of features. Anytime I need a feature, I am able to find it in Oracle Database. It has never happened that I found a feature in any other database, but I was not able to find it in Oracle."
"Oracle Database is easy to install and set up."
"The product has improved organizations by developing BI applications for banks such as a banking data warehouse, fraud detection, incident detection, ad-hoc BI reports shown on maps with drill-down features, data quality process and ETL."
"It provided better insight and diagnostics when data problems were encountered by the application."
 

Cons

"The solution should offer replication. It would be helpful if the solution would allow us to access third-party tools."
"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."
"In my opinion, the packages could be improved. The version I use doesn't allow for packages. I can do some general procedures, but no packages like in Oracle. So, develop separate modules in SQL language. This would be most beneficial for me."
"Continue extending the SQL language for compatibility with the competition's language, including Stored Procedure Language."
"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."
"There should be more intelligence surrounding discovering data to be able to automatically create indexes."
"I would like to see backups from secondary servers."
"Their support and price could both be improved."
"The pricing could be better."
"Oracle Cloud has a bit of a learning curve, so from an improvement perspective, we need to have a simple way to connect to computing in Oracle Cloud."
"Cloud installations using Oracle are not supported by SAP.​​"
"There is a new version of Oracle and Database Firewall, version 20, for which I would be interested in receiving training."
"The initial setup could be easier."
"Their support is terrible. I stand a better chance talking to my four-year-old grandson than talking to them."
"They could improve the scalability a bit. There are other options that are more scalable, for example."
 

Pricing and Cost Advice

"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 product has reasonable pricing. We purchase its yearly license."
"For me, it's always too expensive."
"I do not have first-hand knowledge of the price of the support. However, I have heard from my seniors or the experienced people who work on the pricing and scaling, the price of Oracle is a bit higher. The reason is Oracle provides enterprise-level applications, only large enterprises can afford Oracle applications or tools."
"The price is a little high for the solution, especially when you try and configure it in certain ways."
"Licensing is on a yearly basis."
"The licenses could definitely be cheaper."
"We need to pay an annual subscription for the solution, which is moderately priced."
"The solution is expensive."
"Its cost is astronomical. They charge by the size of the server rather than what you're actually using. It is just a terrible business model. It has got a ton of features that are great, but you have to pay for them, and we don't want to spend a lot of money. If you use any of their additional products, you have to pay for those. Almost everything extra is at an additional charge. We also use RAC, and there is an additional charge for that."
"It is expensive."
