Get feedback from the IBM team to refine your idea
Help IBM prioritize your ideas and requests
The IBM team may need your help to refine the ideas so they may ask for more information or feedback. The product management team will then decide if they can begin working on your idea. If they can start during the next development cycle, they will put the idea on the priority list. Each team at IBM works on a different schedule, where some ideas can be implemented right away, others may be placed on a different schedule.
Receive notification on the decision
Some ideas can be implemented at IBM, while others may not fit within the development plans for the product. In either case, the team will let you know as soon as possible. In some cases, we may be able to find alternatives for ideas which cannot be implemented in a reasonable time.
Allow Informix to accept Non PAM aware clients to connect when using PAM PASSWORD mode
Standard Informix Authentication on unix will perform a getpwnam() call to retrieve the encrypted shadow password from the OS, it will then compare an encrypted version of the password supplied by the client against this, and if they match, authen...
L0 and L1 backups of informix are taking almost same time since it seems that is limited by disk reading performance: we are using IBM spectrum backup to backup.
From IFX logs we see that they are using /usr/informix/server12/bin/onbar_d...
This feature is about having native support to version data within the table. The application will always be able to access the most current data, however through pseudo columns or via other means older version of the data is available. This featu...
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.
Ability to sync tables to HDR & RSS secondaries when converting from RAW to STANDARD mode.
It is significantly faster to load a table in TYPE(RAW) mode than TYPE(STANDARD) mode. However, this option is not practical for sites using HDR and/or RSS secondary servers for replication as RAW mode tables do not replicate forcing the site to b...
Full HDR switch between primary and secondary with a single command and without any downtime
We have 2 servers with 2 HDR instances each.
For each cluster we have also 2 connection manager each.
On server one there is the primary of cluster 1 and the secondary of cluster 2
On server two there is the primary of cluster 2 and the seconda...
Enhance dbschema to generate SQL for sysuser entries
The sysadmin users is used to store:
PAM trusted users (sysauth)
trusted contexts (systcxusers, systcxattributes, systrustedcontext)
local users (syssurrogates, sysusermap)
Dbschema should be extended to allow generated DDL for:
When removing unused indexes the first step we want is to be able to make index invisible to queries similar to the Oracle feature. As the index is still being maintained the rollback to make the index visible to queries is quick.
Evaluate using io_uring for I/O in Informix Linux Platform
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...
