Allow MAX_PDQPRIORITY to be configurable per user.
We want to Informix to be able to use PDQ but we would not want 3rd party logins to be able to use PDQ and impact processing. The existing onconfig parmeter should be a default is it is not defined for the user.
We need to stay with Informix 12 so that our compiled 4GL will continue to work, but we would like to upgrade to RHEL8. Others have done this and it works for them, but my company has to get confirmation that this will be a supported combination f...
Need an onmode option to terminate orphaned, tightly coupled global transactions. Onmode -Z does not address this case.
If a Java application that uses tightly coupled global transactions (such as from Geronimo / WebSphere app servers) abnormally terminates, it may leave the global transaction orphaned on the Informix database server. In this case, an onstat -G wil...
Limit open partitions to avoid very large rsam pool
In systems with a lot of tables informix can have a very large rsam pool. This can cause informix to allocate so much memory it starts swapping or in memory limiting versions (like workgroup, express etc.) to even let the engine crash. Sometimes t...
We raised a support case as follows: Following the recent change in status of Centos, we have customers who wish to convert their Informix servers to Rocky Linux soon. This will be for both IDS 12.10 and 14.10. Can you confirm that IBM/HCL would s...

We want to use CDC to replicate data changes to a different system. We do schema changes once a month, and this complicates things a lot. According to our vendor, this is a limitation for Informix only, other source systems can hande DDL changes t...

Create some performance tests and evaluate an architecture change in Informix to migrate AIO or Kernel AIO to using kernel io_uring Maybe it's not possible to use io_uring in Informix and nowadays, performance increase from using IO_DIRECT KAIO to...
Enhance EXPLAIN in order to no longer need Informix server access
Currently Informix EXPLAIN generates a server side file. For developers that are working from remote machines, it becomes problematic to retrieve the explain files when they have restricted access to the Informix Server machine.
There are 2 undoc...
I would like the ability to create database/SPL's using Informix 4GL syntax and features. I know forms and such wouldn't work but I could then leverage legacy into efficient data retrieval processes for for Java and Typescript to access
