    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).

    The End Subsystem (ENDSBS), End System (ENDSYS), and Power Down System (PWRDWNSYS) commands all have the End Subsystem Options (ENSSBSOPT) parameter. This is nothing new—it’s been there for a long time. In case you are now aware of this parameter, this blog is for you.

    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.

    Trace Output Formatted for PCAP

    Dump a Communications Trace was a blog I wrote back in 2009. That article reviewed the support for dumping the trace data in “packet capture” (PCAP) format and hinted that the DMPCMNTRC command would likely be updated to support this feature (without the need for a data area).

    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.

    Integration Between Navigator and Access Client Solutions

    You should already be familiar with the fact that you can launch Navigator for i from Access Client Solutions (ACS). But did you know that there are now functions, that when requested from Navigator for i, are executed with ACS?

    Client Advisory Council Meetings in June 2017

    If you have wondered why you haven’t seen a new blog published recently, it’s because my day job consumed my time for the past month. I’ve written before about how I work with the Large User Group (LUG), the COMMON Americas Advisory Council (CAAC), and the COMMON Europe Advisory Council (CEAC).  All three of these groups had face-to-face meetings in June that left me with little time for other work.

    Subsystem Configuration Documentation

    Some of you may have read the subsystem configuration experience reports that were written way back in 2004, which was about when V5R3 became available. The experience reports were under the related information section of the Work Management topic.
