I recently answered a Facebook group thread about the frequency of doing an IPL. A couple of people said it’s a best practice to do one every week. One even said it was an “IBM best practice.” Of course, there’s no supporting documentation to support that claim. I’m sure it was an offhand remark by an IBM CE in 1997 while he or she was replacing a 4 GB disk drive. But a weekly IPL as a best practice? I completely disagree. Why? Performance. Database performance specifically. The SQL Plan

When using BRMS control groups (WRKCTLGBRM), it is possible to add user commands using the *EXIT option for the backup item. These commands can run many different backup items or end/start applications. First and Last *EXIT If used, these are processed outside of the control group. The first *EXIT is the pre-control group exit that runs before any of the control group attributes are run (signing off users, ending subsystems, holding job queues, and so on). The last *EXIT is the post-control group and is run after all entries in

BRMS is not a set it and forget it backup and recovery application.  Since BRMS uses database files to store information, some of these files can get large and have many records inserted and/or deleted every day.  There are ways that you can clean up BRMS data files on a regular and as-needed basis. Regular BRMS data files cleanup strategy: BRMS recommends that the Start Maintenance for BRM (STRMNTBRM) command with *YES specified for the reorganize BRMS database (RGZBRMDB) parameter, is run at least once a month to clean up

One of the topics that seem to pop up in my email on a regular basis is SMB. If you have users that access the IFS through Windows file shares or mapped drives, then you’re probably already somewhat familiar with NetServer. NetServer is an implementation of the Server Message Block (SMB) protocol used primarily by Windows clients for file and print sharing. It is to IBM i what Samba is to Unix and similar platforms. Over the years, several different versions of the SMB protocol have been released to address

I have been asked by customers using BRMS, if there is an easy way to exclude objects in the IFS, that are unable to be saved, when using *LINK, to prevent getting the softer error: “Save of list *LINK completed with errors” (BRM10A1 is issued)”. There are several methods: Create and use a BRMS backup list in your backup control group, type *LNK, specifying the IFS directories or files you want to include and omit, and use that as a backup item *LNK in your BRMS backup control group for

Have you ever seen or gotten a BRM1744 during a BRMS full system save or SAVSYSBRM?  Here is what you need to do to resolve this, and I am only going to address V5R3M0 and above. When a SAVSYS is performed through BRMS using a backup control group or the SAVSYSBRM command, BRMS will automatically attempt to end the system to a restricted condition by issuing the following command: ENDSBS SBS(*ALL) OPTION(*CNTRLD)
