Modernization without operational interruptions
MCTL — Mythus Control
Migrating mainframe jobs (JCL/JES2) out of z/OS typically requires rewriting. MCTL converts the original JCL into shell scripts executed by the Mythus framework on Linux, preserving queues, scheduling, and the operations console in the z/OS standard.

Migrating or synchronizing data between heterogeneous databases — especially those involving Adabas — typically requires downtime, nightly ETLs, or application rewrites. MDBM replicates in real time between relational databases, near-real-time from Adabas to relational (Oracle, SQL Server, PostgreSQL, MySQL, and Firebird) by reading the PLOG, and Adabas to Adabas (ADA2ADA), keeping source and target synchronized without interrupting production.

Legacy systems in Natural/Adabas rarely record who did what, leaving critical gaps in audit and compliance. MAUD reconstructs this trail in a 6-phase pipeline, cross-referencing Natural Security, PLOG Adabas, DDMs, OS auditd, batch jobs, and corporate security — answering who did what, when, where, and how.

Modernizing Natural applications without a dependency map is risky and leads to costly rework. MNAE reads SYSOBJH dumps and generates AST in JSON for programs, subprograms, subroutines, DDMs, and data areas, extracting dependency metadata for impact analysis and migration planning based on real source code data.

NaturalONE locks the developer into Eclipse and the Software AG stack (EntireX, NDV). MNDD is a Linux daemon in C that exposes Natural via HTTP/JSON and transforms VS Code into a native IDE, with a virtual filesystem mndd://, syntax highlighting, pagination, and native Git.

Frequently Asked Questions
Mission-critical systems are those whose unavailability or failure causes direct and severe impact on business operations — financial, operational, or regulatory. Examples include banking processing platforms, payroll systems, large-scale ERPs, and telecommunications infrastructures. Mythus Solutions specializes in ensuring the availability, performance, and secure evolution of these systems, including IBM z/OS mainframe environments.
Our team has proven expertise across a broad technology spectrum: ADABAS/NATURAL for legacy mainframe databases and applications; Java for API development, microservices, and modern integrations; PostgreSQL for high-performance open-source relational databases; Linux in on-premise and cloud server environments; and IBM z/OS as the reference mainframe platform. We operate in both the maintenance of existing systems and the gradual modernization of these stacks.
We adopt a gradual migration approach, avoiding the risk of the "big-bang" model. The process begins with a detailed assessment of the current environment, followed by a phased modernization plan. Each phase is executed incrementally — keeping legacy systems in production while new modules are validated — until complete and safe replacement. This minimizes operational risks, preserves accumulated knowledge in the legacy system, and allows adjustments throughout the project.
Yes. Our headquarters is in João Pessoa (Paraíba), but we serve clients throughout Brazil and internationally. The majority of projects are conducted remotely, with on-site visits planned as required by each engagement. We have delivered projects for organizations in both the public and private sectors across various regions of Brazil.
We offer a support model structured around four dimensions: contractual SLA with response and resolution times defined by severity; preventive support with proactive monitoring and trend analysis to prevent incidents; corrective support for rapid failure handling and service restoration; and evolutionary support for maintenance, updates, and continuous improvements. The scope and levels of each dimension are agreed upon according to the client's profile and environment criticality.
