  • i Can use IBM DVD Images with my USB 3.0 Adapter

    IBM i began supporting USB flash drives back in 2012, but their use was restricted to save/restore and IFS options (refer to the blog IBM i Now Supports USB Flash Drives for additional background information).

    Manage Trigger Programs in Productions

    This week’s blog was written by Scott Forstie. Scott is the Db2 for i Business Architect, SQL development leader, and IBM i developerWorks content manager.



    Trigger programs are a data-centric technology to deploy business logic by establishing code that will run (fire) when the associated triggering event occurs. Trigger programs have been around a long time and come in two forms:

    1. 1) Native Triggers – managed with the Add Physical File Trigger (ADDPFTRG), Change Physical File Trigger (CHGPFTRG), and Remove Physical File Trigger (RMVPFTRG)
    2. 2) SQL Triggers – managed with the CREATE TRIGGER, ALTER TRIGGER, and DROP TRIGGER SQL statements. More recently, users have been able to also use CREATE OR REPLACE TRIGGER to simplify trigger deployment.
