migrate-oracle-forms

A migration guide for converting Oracle Forms applications into Mendix applications. Oracle Forms is a legacy tool for building database applications, while Mendix is a low-code development platform.

In plain words
What is it for?
It helps translate .fmb forms to Mendix pages, PL/SQL triggers and procedures to microflows, Oracle tables to entities, and form navigation to page navigation.
Why use it?
It provides mappings for moving old forms, database models, business logic, and navigation into a different application structure.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

migrate-oracle-forms scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Oracle Forms to Mendix Migration Skill

This skill provides comprehensive guidance for migrating Oracle Forms applications to Mendix using MDL (Mendix Definition Language).

When to Use This Skill

Use this skill when:

  • Converting Oracle Forms (.fmb) applications to Mendix
  • Translating PL/SQL logic to Mendix microflows
  • Mapping Oracle Forms UI elements to Mendix widgets
  • Planning a migration strategy for legacy Oracle Forms systems

Migration Overview

Oracle Forms migration to Mendix involves:

  1. Data Model: Oracle tables → Mendix entities
  2. Business Logic: PL/SQL triggers/procedures → Mendix microflows
  3. User Interface: Forms blocks/items → Mendix pages/widgets
  4. Navigation: Form canvases → Mendix page navigation

Reserved Word Conflicts

Most common words (check, text, format, value, type, index, status, select, etc.) now work unquoted as attribute names in MDL. Only structural keywords (create, delete, begin, end, return, entity, module) need quoting.

Naming Best Practices

While most words are no longer reserved, using descriptive names is still recommended for clarity:

Oracle Forms Field Recommended Mendix Name Notes
check check or CheckStatus Works unquoted
text text or TextContent Works unquoted
format format or FormatType Works unquoted
value value or FieldValue Works unquoted
Name Name or ItemName Works unquoted (not a keyword)
type type or ItemType Works unquoted
create "create" or CreatedBy Requires quoting (structural keyword)
delete "delete" or IsDeleted Requires quoting (structural keyword)

Example

create persistent entity MyModule.FormField (
  check: boolean default false,  -- Works unquoted
  text: string(500),             -- Works unquoted
  format: string(50),            -- Works unquoted
  CheckFlag: boolean default false, -- Renamed alternative (also fine)
  TextContent: string(500), -- Renamed
  FormatType: string(50)    -- Renamed
);

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

migrate-oracle-forms is a skill published in the GitHub repository mendixlabs/mxcli (115 stars, last pushed 2d ago), licensed Apache-2.0. It adds 47 tokens to every session and 3,370 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
