Techical Tips for i by Dawn May
New with the 7.3 release is the ability to automatically download PTF groups to your IBM i partition. The PTFs are downloaded in save files and stored on your system, ready to be installed. This enhancement was requested by requirements received through the COMMON Americas and COMMON Europe Advisory Councils.
While I was at the Power Systems Technical University in London a couple of weeks ago, a conference attendee in my work management presentation asked me this question: “How do I make WRKJOB, option 14 (display open files), display the I/O information rather than the activation group information? I always have to press F11 to see the I/O details.”
I’d like to thank MJ Thompson for writing this week’s blog. MJ is part of the BRMS development team at IBM in Rochester, MN. Thanks MJ!
In release IBM i 7.1 and later, IBM Backup, Recovery and Media Services for i (BRMS) has been enhanced to support the transfer of virtual save media from image catalogs to/from the cloud using product 5733ICC – Cloud Storage Solutions for i. Cloud Storage Solutions for i allows cloud connector resources to be defined for cloud storage providers such as IBM’s SoftLayer and for private interfaces such as file transfer protocol (FTP).
When you sign in to Navigator for i on a partition that is running the 7.3 release, you will discover a new option to display the dashboard.
I’d like to thank Mike Russell, software engineer at IBM, for writing this blog article.
In the 7.3 release, IBM added a new parameter to the End Job Abnormal (ENDJOBABN) command.
Recently I wrote about IBM i 7.3 System Monitor Enhancementsand mentioned the default monitor collection interval was changed to 60 seconds. On the 7.2 release, the default collection interval was 15 seconds; IBM has recently changed the default on 7.2 to 60 seconds. For this change, you will need the Navigator service pack that was made available this past June. You can find the details of the required PTFs and PTF Groups on the developerWorks page for Navigator PTFs.
System Monitor support was added to Navigator with the 7.2 release. Navigator system monitors are similar to Management Central system monitors—they allow you to monitor a set of metrics in real time with the option to set thresholds and define actions to take when those thresholds are hit. However, system monitor support in 7.2 had limited ability to visualize metrics.
IBM receives many requests for the IBM i operating system to process all resources directly out of stream files. An enhancement added in version 7.3 puts IBM i closer to that goal.
I wrote about workload groups some time ago in “i Can … Manage Workloads Better with IBM i 7.1”. The information in that older article is still accurate, and I’m not going to repeat a lot of what I wrote there. If you have not yet used workload groups, you may want to read the older blog for additional information on why workload groups are useful.
Another day, another security vulnerability. System administrators everywhere battle daily to keep their systems secure. When security algorithms are deemed vulnerable or another network attack is disclosed, how do you know if you’re impacted? How many issues could be caused by turning a weak security algorithm off? Tracing network traffic and analyzing the data is a tedious task and isn’t always straightforward.
Back in 2013, IBM first published the IBM i Performance FAQ; this document is a fantastic resource on all types of performance topics. It reviews the various components of system performance, discusses benchmarking, sizing and capacity planning, monitoring, and covers the performance tools that are available on i. The document has answers to many commonly asked questions, and ends with an extensive list of references. I first blogged about it here.
This week, I’m going to share a super-secret enhancement in the 7.3 release. The Display Job Log (DSPJOBLOG) command was enhanced with two new parameters: MSGF and DUPJOBOPT.
I initially wrote about the SET_SERVER_SBS_ROUTING procedure in this post, Route DB2 Requests to a Specific Subsystem, and then again in this post, Route Remote Command Requests to a Specific Subsystem. I’m back again with another post to tell you about more enhancements to this IBM i Service.read more…

IBM i backup strategies may use journaling to shorten or eliminate down time for applications during backups. BRMS provides special control group entries which assist in backing up journal receivers for these backup strategies.read more…
I’m sure most of you know how you can use Qshell to get a Unix -like interactive environment. You start an interactive Qshell session by using the Start QSH (STRQSH) or QSH command with *NONE for the CMD parameter.read more…
IBM i 7.3 is here! IBM i 7.3 has added a feature called “Security Authority Collection” which tracks how applications and application users “use” an object. Inquiries against that collection will provide advice on securing critical business data and applications from intrusion by identifying who needs to have access to data and in what context. This is a major enhancement to security management that is unique to IBM i.read more…
