Legops

You can manage LegOps in the Resource Center under the Legops tab.

🎯 What is a LegOps?

A LegOps (Legacy Operations) defines:

• The type of backend system you're connecting to
• Connection details (host, credentials, etc.)
• Rules for which files to retrieve (filters, patterns, etc.)

Once defined, a LegOps can be used to explore remote systems and fetch source files such as COBOL programs, or PCML wrappers.

🧭 How to Create a LegOps

1. Go to Resource Center → Legops

2. Click ➕ New Legops

3. Fill in the required fields:

   • Select the Type
   • Enter a Name and optional Description

4. Fill in Configuration

5. Provide the Connection Properties

6. Save the LegOps

💡 You can also test the connection and preview available files after saving.

🛠 Supported LegOps Types

Type	Description
as_400	IBM AS/400 environments
mf_rse	Mainframe via RSE (Remote System Explorer)
ftp	Generic FTP server

Each type has a tailored configuration experience.

🧩 LegOps Structure

1. Basic Info

• Type: Select one of the supported backend types.
• Name: A unique ID for this LegOps.
• Description (optional): Notes about this connection.

---

2. Configuration Fields

Depending on the selected type, you’ll see different configuration fields:

Common Fields

Field	Description
Pattern	File name or dataset filter (e.g. .*PGM, UNIT*)
Recursive	If checked, searches subfolders/datasets (where supported)

AS_400

Field	Description
Library	The AS/400 library to scan

MF_RSE

Field	Description
Dataset	Dataset filter, e.g. ${HLQ}.**
Auto-detect File Extension Strategy	How to determine file types (see below)
Manual File Extension	Override the file extension manually

File Extension Strategies (MF_RSE)

Strategy	Behavior
AUTO	Uses server metadata or content
SERVER_BASED	Uses server-side mappings
CONTENT_BASED	Uses file content to infer type
NONE	No detection applied

---

3. Connection Properties

These fields vary per backend type, but generally include:

• host
• port
• user
• password
• encoding
• timeout (optional)

You must fill these in correctly to fetch files or test the connection.

📁 What Happens After Creation?

Once a LegOps is created:

• You can view it from the Legops tab in the Resource Center.
• You can fetch files using the pattern and connection details defined.
• The fetched files can then be used for analysis, conversion, or enrichment inside the Hub Apps.

💡 Tips & Best Practices

• ✅ Use specific patterns to narrow file searches.
• 🧪 Test connections to ensure your credentials and filters are correct.
• 🧵 Use AUTO file extension detection as a starting point for MF_RSE.
• 🔁 LegOps definitions are reusable across the platform — define once, use often.
