1. Adabas & Natural for z/OS

1.1 Natural for z/OS

Natural for z/OS 9.2.5 includes new features that improve operations and developer productivity.

The headline of this release is new capability rather than maintenance. Natural Messaging arrives as a new product on z/OS, connecting your Natural applications directly to IBM MQ with the familiar PUT, GET and BROWSE statements - so business events flow between the mainframe and your distributed systems in real time, with no custom plumbing to build or maintain. Alongside it, a new subprogram server opens the door to Natural API Server, letting you publish existing Natural business logic as secure REST APIs that cloud, mobile and AI-driven applications can consume.

Developers gain a richer, more expressive language. Nested PARSE statements simplify complex XML and document handling, wildcards in edit masks and new formatting options for hex data (commas or blanks) reduce hand-written workarounds, and spacer elements (nX) in COMPRESS make generated output easier to control. Together these enhancements mean less boilerplate code and cleaner programs that are quicker to write and easier for the next developer to read.

Operations and diagnostics get equal attention. Higher precision in *CPU-TIME and Adabas call counters extended to I4 give you accurate measurement of today’s workload volumes; improved RPC server logging and new trace capabilities for the Natural Roll Server shorten the path from symptom to root cause; and Editor Buffer Pool recovery file management protects work in progress. Installation is simpler too - Natural can now be installed using z/OSMF, aligning with the standard IBM tooling your systems programmers already use.

The wider product family moves forward in step. Natural for Db2 now supports Db2 AI statements natively, bringing AI-driven insight to your data without leaving Natural. Natural Security adds password and passphrase handling without the ICU dependency, simplifying deployment, and both Natural for z/OS and Natural Security ship with VPAT-based Accessibility Conformance Reports (ACRs). Natural Development Server follows as a maintenance release and Predict is re-released, keeping your full z/OS stack current and supported.

1.2 Adabas for z/OS

Release Highlights Summary for

• Adabas for z/OS (ADA 8.6.2) and Add-Ons
• Event Replicator Target Adapter (ART 4.1.0) and tools
• Adabas Analytics Collector (EAP 4.1.0)
• Event Replicator Server (ARF 4.2.2)
• Adabas Manager (AMN 9.5)
• Entire Net-Work (WCP 6.6.2)

This release brings targeted improvements to the core Adabas for z/OS database, meaningful upgrades to Event Replicator and auditing capabilities, and continued consolidation of administration tools into Adabas Manager. Alongside these, several components ship as straightforward maintenance releases, keeping the overall platform current and stable.

On the core database side, ADASAV now specifically supports IBM’s Extended Address Volumes (EAV), which significantly improves performance when working with EAV volumes and lets customers make fuller use of their large disks. This can also simplify database administration, since one large dataset can be used instead of managing several smaller ones. In addition, basic administration of Stored Procedures and Triggers (SPATs) has been built into the Adabas Manager Communicator (AMC), laying the groundwork for fuller support in a future Adabas Manager release.

Event Replicator sees two notable additions. The Event Replicator Server now includes initial auditing support: Audit data is written to a dedicated Adabas database, from where it can be processed further using standard tools such as Natural or replication. IBM Guardium Data Protect is also supported as a target for security metadata (excluding business data), in line with Guardium’s own rules. This release spotlights the existing support for long alpha fields in both Event Replicator Server and the Event Replicator Target Adapter.

Administration continues to consolidate into Adabas Manager. Event Replicator can now be defined directly within Adabas Manager, bringing in the major functionality previously found only in the standalone Event Replicator Mapping Tool (AMT), following similar Target Adapter Administration capabilities (AMR) already introduced in AMN 9.4 (previous version). As part of this shift, the standalone AMT and AMR rich-client tools are being retired and will no longer be released starting with the next major/minor release in October 2027, so customers relying on those tools should plan to transition to Adabas Manager.

Rounding out this release, the Adabas Analytics Collector MF (EAP 4.1.0) and Entire Net-Work (WCP 6.6.2) both ship as maintenance releases, with no new functional highlights to report.

2. Adabas & Natural for Linux & Cloud

2.1 Natural for Linux & Cloud

Natural for Linux 9.3.4 and its product family, in alignment with Natural for z/OS, provides new features and new statements as shown in the table below.

Natural for Linux and Cloud moves in lock-step with z/OS, so a single code base keeps working wherever you choose to run it. The same language enhancements apply here: spacer elements (nX) in COMPRESS, wildcards in edit masks, and commas or blanks to format hex data - less workaround code, cleaner programs, and no surprises when applications move between platforms.

The release also opens your Natural logic to the wider world. Natural API Server (NPI 1.1.1) is supported through a new OpenAPI Server as well as new Subprogram Server components, turning existing Natural subprograms into secure REST APIs based on the OpenAPI standard, which cloud-native, mobile and AI-driven applications can call directly - modernizing your integration layer without rewriting proven business logic.

Scale and observability improve where it counts for growing workloads. A higher MAXUSER limit in the buffer pool, an increased Adabas call counter limit, and protocol level 4 with enhanced precision accommodates today’s larger user populations and transaction volumes. Higher precision *CPU-TIME and a new user exit that reveals the USIZE actually consumed by a Natural runtime. The surrounding product family advances too. Natural Development Server adds detailed new log files for faster troubleshooting; Natural Availability Server introduces client HTTP file transfer and a custom client-side theme so you can align the user experience with your corporate look and feel; Natural Security lets you maintain passwords and passphrases independently and ships enhanced API documentation; and Predict is re-released. VPAT accessibility documentation now accompanies Natural for Linux and Cloud and Natural Development Server, supporting your procurement and compliance requirements.

2.2 Adabas for Linux and Cloud

Release Highlights Summary for

• Adabas for Linux and Cloud (ADA 7.5)
• Adabas Encryption for Linux (AEL 7.5)
• Adabas Cluster for Linux (ADC 7.5)
• Adabas Manager (AMN 9.5)
• Adabas Event Replicator for Linux & Windows (ARN 15.0)

This release of Adabas for Linux and Cloud brings a well-rounded set of improvements across security, observability, usability, and high availability. Rather than one headline feature, the update focuses on strengthening the everyday reliability and manageability of your Adabas for Linux and Cloud environment — from better visibility into what the database is doing, to tighter protection of data and credentials, to smoother operations for database administrators.

On the core database side, administrators get much better insight and protection out of the box. The nucleus log now lists used license files with their location and lifetime. OpenTelemetry support through the REST administration service exposes key monitoring metrics and log entries for easier integration with modern monitoring tools. A new safeguard prevents a second nucleus from starting against the same database, protecting against accidental data corruption. Diagnostic tooling has also improved, with the system now warning if the recommended Linux GDB tool is missing, since it significantly speeds up error diagnosis when problems occur.

A notable modernization step is the introduction of long names for database fields, alongside the start of token-based authentication. Long field names make table structures easier to read and maintain, and are fully backward compatible with existing applications, which will be able to adopt them as broader tool support (Natural, Predict, CONNX, and others) becomes available. Token-based authentication begins rolling out as an alternative to traditional user ID and password logins, starting with support across all Adabas utilities, while continuing to work alongside existing role-based access control.

Security-conscious customers will appreciate the enhancements to Adabas Encryption for Linux. Audit logging is now configurable per database for more precise control, and both the Key Encryption Key (KEK) and Data Encryption Key (DEK) can now be rotated to comply with key-lifespan policies, using new and existing utilities respectively. Communication between cluster nodes can now also be secured with TLS/SSL, closing another gap in end-to-end data protection.

Finally, replication, clustering, and management capabilities continue to mature. Event Replicator for Linux & Windows now supports Adabas Cluster for Linux, enabling organizations to combine real-time data replication with clustered database environments for greater resiliency and scalability.. Adabas Cluster for Linux now supports read-only access to secondary nodes, allowing read-heavy applications to be load-balanced away from the primary node, alongside the same secured intra-cluster communication introduced for encryption. Adabas Manager rounds out the picture with support for the new flexible UTC or local-time logging, and new options to capture detailed database statistics and file update timestamps for better operational oversight.
