  • Ways to Work With Your JVMs

    “i Can…Work With Your JVMs” was one of the very first ‘i Can’ blogs written. That blog covered the commands that were new in the IBM i 6.1 release for working with your JVMs.

    Since that blog was written, additional interfaces have been added to the operating system that expand the ways in which you can work with your JVM jobs.

    Routing Work to Subsystems

    In the blog Route DB2 Requests to a Specific Subsystem, I wrote how you can use the new QSYS2.SET_SERVER_SBS_ROUTING procedure to route work for database queries using the QZDASOINIT or QRWTSRVR server jobs to customized subsystems. This is a new way to route work based upon the requesting user profile that augments the other ways you can route work to subsystems.

    PowerVP Offers New Features

    When IBM released PowerVP a couple of years ago, it was designed to optimize your virtualized Power Systems servers and help you understand your current workload performance from virtual machines to physical hardware. This can help you more quickly identify overcommitted resources and resolve performance issues.

    Route DB2 Requests to a Specific Subsystem

    We all know that a key advantage to IBM i is the work management capabilities, in particular the ability to segregate work into different subsystems. One of the more challenging areas for this, however, has been prestart server jobs.  By default, these prestart jobs run in the QUSRWRK subsystem.  You can configure the subsystem in which these prestart server jobs run by routing the requests based upon the client IP address, but that’s often not sufficient.  Many requests may come from one IP address, or perhaps you would like to segregate work based upon some other criteria - for example, the requesting user profile.

    IBM i 7.2 Improved Temporary Storage Tracking (Part 6)

    The IBM i Temporary Storage Service allows you to use SQL to retrieve information about the temporary storage buckets. You can view the temporary storage buckets in Navigator for i, but there is no command interface to display that information. If you need a text-based interface to display the buckets, this temporary storage service is how you do it.

    Tracking IBM i System Limits, Part 2

    My last blog was an Introduction to IBM i System Limits and Maximum Capacities. In that blog, I introduced System Health Services, which allow you to track system limits. System limits tracking support is provided via DB2 PTFs, so be sure to install the latest DB2 Group PTF when you start to explore this capability. The limits tracked vary by release and DB2 Group PTF level.

    Introduction to IBM i System Limits and Maximum Capacities

    We all know that IBM i is a very scalable platform. It supports businesses from the very small to the very large. However, as the workload running on an IBM i partition increases and becomes large, knowing the limits of your system becomes increasingly important.
