RPG User-defined Functions (UDFs) & Table Functions (UDTFs)
RPG is the best language in the world for writing business rules. But what happens when you want to use those business rules from SQL? Or from a web application that accesses your business logic through SQL? DB2 for i lets you write User Defined Functions (UDFs) in high level languages like RPG. UDFs can be called from SQL statements run from anywhere, including ad-hoc queries, SQL run from web applications, and SQL run from the embedded SQL precompilers used by RPG and other languages.
UDFs can even return a table (often called a UDTF, User Defined Table Function) which lets them do the same sort of work that a stored procedure would do -- but unlike stored procedures, they can return result sets to any language, including PHP, Java, .NET and embedded SQL written in ILE RPG.
UDFs are a powerful tool for any programmer's toolbox.
1. The Concept of SQL Routines
2. How to write an external UDF in RPG
3. How to write an external UDTF in RPG
All experienced RPG programmers.
PHP, Java or SQL programmers who'd like to reuse existing RPG code.
Setting Up and Scripting the OpenSSH, SFTP, and SCP Utilities
It seems like everyone today is using the FTP protocol to send files. One problem: It's not very secure!
For security's sake, a lot of companies need to use SSH tools, including SSH itself, as well as the SCP and SFTP utilities. IBM provides the OpenSSH software to IBM i customers free of charge, but it runs in the PASE environment.
If you're not familiar with Unix, how do you set up OpenSSH? How do you use it? How can your RPG or CL programs run SFTP scripts? This session will tell you how.
1. Setting up OpenSSH on i
2. The OpenSSH tools, SSH, SFTP and SCP. What are they good for? How do you use them?
3. How do you write programs/scripts in native languages that use the SSH tools?
Programmers that need to transfer files securely with the the SSH tools.
