iLibrary 0.0.12

iLibrary - Tools for IBM i library

iLibrary

A lightweight Python helper for working with IBM i (AS/400) libraries. It connects via ODBC (pyodbc) for DB2/SQL queries and uses Paramiko for SSH/SFTP to save and transfer library save files (SAVF).

Overview

• Query library metadata using QSYS2 services
• List objects in a library (and optionally source physical files)
• Create a save file (SAVF) for a library via SAVLIB and optionally download it
• Remove save files
• Simple context manager to handle DB connection lifecycle

Requirements

• Python 3.8+
• IBM i system access
• IBM i Access ODBC Driver (or compatible) installed locally
• Network access to the IBM i for ODBC and SSH/SFTP

Installation

• From PyPI: pip install iLibrary
• From source:
  • Clone the repo
  • Optionally create and activate a virtual environment
  • pip install -r requirements.txt
  • pip install -e .

Quickstart

from os.path import join, dirname
import os
from dotenv import load_dotenv
from iLibrary import Library

# Load ENV file and get the connection settings
dotenv_path = join(dirname(__file__), '.env')
load_dotenv(dotenv_path)
DB_DRIVER = os.environ.get("DB_DRIVER")
DB_USER = os.environ.get("DB_USER")
DB_PASSWORD = os.environ.get("DB_PASSWORD")
DB_SYSTEM = os.environ.get("DB_SYSTEM")

with Library(DB_USER, DB_PASSWORD, DB_SYSTEM, DB_DRIVER) as lib:
    print(lib.getLibraryInfo('QGPL', wantJson=True))
    print(lib.getFileInfo('QGPL'))

Save a library to SAVF and optionally download it

from os.path import dirname

with Library(DB_USER, DB_PASSWORD, DB_SYSTEM, DB_DRIVER) as lib:
    ok = lib.saveLibrary(
        library='MYLIB',
        saveFileName='MYLIBSAVE',
        description='Backup',
        localPath=dirname(__file__),
        remPath='/home/MYUSER/',
        getZip=True
    )
    print('Saved:', ok)

API overview

• Library(db_user, db_password, db_host, db_driver)
  • enter / exit for connection lifecycle
  • iclose(): manually close the connection
• getLibraryInfo(library: str, wantJson: bool = True) -> str | tuple
• getFileInfo(library: str, qFiles: bool = False) -> str
• saveLibrary(library: str, saveFileName: str, ..., getZip: bool = False, ...) -> bool
• removeFile(library: str, saveFileName: str) -> bool

Configuration

• Environment variables expected:
  • DB_DRIVER: e.g. {IBM i Access ODBC Driver}
  • DB_USER
  • DB_PASSWORD
  • DB_SYSTEM
