Informix 2026: v15, watsonx and 12.10 end-of-support
Informix in 2026: v15, watsonx and end of support for 12.10.
Three concrete movements — including an end-of-support that already kicked in — plus IBM's strategic push into analytics and AI. If you run Informix in production or are evaluating it, this is the map worth keeping current.
Informix is one of those databases people occasionally write off — and a couple of years later it's still in production across thousands of organisations running OLTP, time-series and IoT workloads. So far in 2026, three concrete things have happened that are worth knowing about.
At SIXE we deliver the three official Informix courses aligned with the v15 line, and we work with customers running Informix in production for years. Here's the useful recap: what's on the table, which dates matter, and where it fits.
General availability
Latest fixpack
Already in effect
Three movements on a single timeline
If you only have 30 seconds, this is the summary — the rest of the post unpacks each point:
Informix 15 consolidates the line
Removal of internal limits, storage up to half a yottabyte, external smartblobs and refreshed InformixHQ. The most relevant engine update in over a decade.
14.10xC13 (January 2026)
archecker now restores tables with SmartLOB (BLOB/CLOB) columns from backup. Direct I/O with 2K and 4K block sizes. Usual rollup of accumulated fixes.
EOS of 12.10 — in effect
Informix 12.10 has been out of standard support since 30 April 2026. IBM offers Extended Support contractable through 2030 as a bridge for organisations that need one.
What Informix 15 brings
Version 15 — officially announced by IBM on 19 November 2024 — is the most significant engine update in over a decade. Key changes:
- Storage without practical limits. A single Informix 15 instance can manage up to half a yottabyte of data. Removing the internal caps (rows per page, pages per partition, page sizes) means you no longer partition tables to work around the engine — you partition them when it makes functional sense.
- External smartblobs. BLOBs and CLOBs (videos, documents, multimedia) can now live on an external filesystem. Faster backups and cheaper storage.
- Refreshed InformixHQ. The graphical monitoring and administration tool gets easier Enterprise Replication configuration.
- Better diagnostics. Improved SQL debugging to speed up developer work.
For many Informix deployments, table partitioning was driven by the engine's internal limits rather than by business need. That changes with 15: you partition because it makes sense at the data-model level, not because the engine forces you to.
What 14.10xC13 brings (January 2026)
If your organisation is still on the 14.10 line — and that's perfectly fine, it's still a supported release — the latest fixpack shipped in January brings:
archeckernow restores tables with SmartLOB (BLOB / CLOB) columns from backup. Until now this scenario was more manual.- Direct I/O with 2K and 4K block sizes, on top of the previously available sizes. Finer control over I/O performance.
- Usual rollup of accumulated fixes and stability improvements.
14.10xC13 is the maintenance release designed to keep the line healthy while you plan the jump to 15.
Informix in the watsonx.data ecosystem
IBM has published an official Informix connector inside watsonx, also documented in the watsonx SaaS docs portal. The value proposition:
- Zero-ETL. The connector queries Informix data without replicating it to a separate data lake. One copy. IBM puts it literally: "access and query multi-modal data types in IBM Informix [...] with zero-ETL".
- Open formats in watsonx.data. watsonx.data itself uses Apache Iceberg as an open table format to unify and share data across integrations (Db2, Netezza, Informix and others) without re-cataloging. Your data in Informix stays Informix.
- Natural-language queries. watsonx.data's generative AI capabilities — per IBM — allow Informix customers to analyse data "using natural language with no SQL required".
For an organisation with Informix already installed, this integration turns the operational base into an analytical asset too — with no migration or replication.
If your organisation is already using or evaluating watsonx.data, the Informix integration removes one of the typical objections: "how do I connect my operational data to the AI layer without setting up a separate pipeline".
Informix 12.10 — out of standard support since 30 April
Since 30 April 2026, Informix 12.10 (Enterprise, Workgroup and Express editions) is out of IBM standard support. Organisations still running 12.10 can contract IBM Extended Support with coverage through 2030 as a bridge. Without either, there are no security patches or incident resolution from IBM.
Practical implications:
- The 12.10 line no longer accepts new license purchases.
- Instances on 12.10 without an extension are without patches or official support since 30 April.
- Extended Support is the contractable route to extend coverage through 2030 — useful as a bridge while planning migration.
- The usual upgrade path leads to the latest supported release (Informix 15). 14.10 is a valid intermediate stop if application compatibility requires it.
Compatibility and suggested moves
Where Informix fits well in 2026
Scenarios where Informix remains a competitive option:
- Intensive OLTP with low latency. Retail, point of sale, banking, telco — memory footprint and per-core performance remain among the best in the market.
- IoT and time series. The engine supports temporal types and time-series management natively, without depending on external solutions.
- Edge computing. Informix Embedded is designed for devices with constrained hardware and intermittent connectivity — kiosks, remote stores, industrial equipment.
- Long-running databases. When you already have 12.10 or 14.10 in production, the natural path is to move up to 15 — keeping the team's knowledge, applications and existing integrations.
On top of that, the operational upside of a single vendor (IBM) for support, official training and partners with real production experience.
The three courses we deliver
In SIXE's Informix training path we deliver the three official IBM courses aligned with version 15:
Online or on-site, in English, with labs on real infrastructure. Delivered by the SIXE engineers who run Informix at customer sites. In-company from 2 attendees, with volume discount.
The essentials in 4 points
→ Informix 15 (Nov 2024) removes internal limits, adds external smartblobs and refreshes InformixHQ. Target line for migration.
→ 14.10xC13 (Jan 2026) brings SmartLOB restore via archecker and direct I/O in 2K/4K blocks. 14.10 remains a supported version.
→ 12.10 has been out of standard support since 30-Apr-2026. IBM Extended Support contractable through 2030 as a bridge.
→ watsonx.data integration with zero-ETL connector and open Iceberg format — operational data turns into analytical asset without replication.
Frequently asked questions
Is IBM Informix still officially supported in 2026?
Yes. Informix 15 is the active line. Informix 14.10 is still a supported release receiving fixpacks (the latest, xC13, shipped in January 2026). Informix 12.10 has been out of standard support since 30 April 2026; IBM offers Extended Support contractable through 2030 for organisations that need to extend coverage.
Does the watsonx.data integration require moving data elsewhere?
No. The zero-ETL connector accesses Informix wherever it lives (on-premises, cloud, hybrid) without replicating data. One copy, two consumption planes: operational and analytical.
What is HCL's relationship with Informix?
HCL and IBM have co-licensed Informix since 2017. Both IBM Informix and HCL Informix exist with the same technical base and equivalent version numbers (15.0). SIXE's official courses are IBM.
Is it worth migrating to Informix 15 if I'm on 14.10?
Worth planning. The structural changes (removal of internal limits, external smartblobs) are significant, and the watsonx.data connector is aligned with the active line. 14.10 is still a supported release, so the jump can be planned without rush.
I'm on Informix 12.10. What now?
Standard support ended on 30 April 2026. Options are to contract IBM Extended Support (coverage through 2030) as a bridge, or to plan migration. Upgrading to the latest supported release (15) is the usual path; 14.10 works as an intermediate stop if application compatibility requires it.
