    System Monitoring for HTTP

    I’ve written about system monitors in Navigator for i two times before; first when system monitors were added to Navigator in IBM i 7.2, and then later, when system monitors were enhanced with Visualize Monitor Data in the 7.3 release (which has also been taken back to IBM i 7.2).

    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.

    Route FTP and SMTP Workloads to Their Own Subsystem

    Way back in V5R1, IBM introduced the ability to route FTP and SMTP workloads to their own subsystems. By default, FTP and SMTP server jobs run in the QSYSWRK subsystem, along with a lot of other IBM i server jobs. The Server Table in the IBM i Knowledge Center documents all the IBM i server jobs along with the default subsystem in which they run. The server table does state the subsystem is configurable for these servers, but it doesn’t give you any more information.
