August 2011 Newsletter
i can do anything with iTech Solutions
First, we hope that you and your families are safe and dry after this weekend’s hurricane. We are all glad to see Irene leave the area. Our phones at iTech Solutions never stopped ringing on Friday as customer after customer called with questions. We were glad that we were able to help so many of you. As with any event like this, we need to reflect on the things we have learned from Hurricane Irene. Our procedures, our backups, location of our tapes, electrical requirements, machine location, etc. I hope you spend the coming week looking back on what you should improve, what steps you can change to make things better, or how you should be testing your disaster recovery procedures. An event like this or similar will happen again, and you need to make sure you are prepared. When was the last time you tested your backups by recovering your system? If you answered never, you really need to think about testing your recovery.
Each month our newsletter brings to light tips and techniques that help many System Administrators in their job, as well as managers know what is happening in the IBM i world. We are happy to be able to help so many people in the IBM i community. The number of iTech Solutions customers is growing each month, and that is due to our commitment to our customers, our services, and the support that we provide. Find out for yourself what it is like to work with a business partner who cares about you and your success.
Due to Hurricane Irene, I am going to focus this month’s articles on Backup, Recovery, and Planning. This issue of our newsletter has five articles. In the first, we look at a iTech Solutions Cloud Based Backup Solution. Giving you the ability to easily and efficiently backup your system to our Virtual Tape Vault, getting your data immediately off-site. How handy would that have been this past weekend? The second article is How to Recover your system. The third article lists some of the upcoming events in which iTech Solutions will be participating. The fourth article is how to start journaling all objects in a library. The last article is for your reference with updated PTF information.

| System Recovery.
Last week, iTech Solutions sent out a special newsletter right before Hurricane Irene hit the area on backing up your IBM i. We discussed what you needed to do to get a full backup. While it makes your recovery extremely easy if you had the luxury of being able to perform a full backup every night, not everyone is able to do a full backup each and every night.
Therefore, the recovery is about putting the pieces back together in the right order and correctly. We do this all the time with customers as we test their recovery. Before you can recover your machine, you need to know and understand what was backed up and how. If you have BRMS then it is extremely easy, as BRMS creates a recovery report that you print out each day. If you are using BRMS and don’t print the recovery report (or have access to it when you need it), you don’t stand a chance to recover that system.
For everyone who doesn’t use BRMS (If you don’t know what BRMS is, you probably don’t use it) you should print your backup procedures and keep them with your tapes. This could be in the form of what you do for daily, weekly, and monthly backups, or even better the actual CL Programs that are used for your backups.
The next question we always seem to get in a recovery is “So, what exactly should I be backing up each night?”. The answer to that question is it depends on a few items: the size of your backup window, if you can be in a restricted mode, will everything fit on one tape, object locks, and the size and number of objects. For those customers who have a large backup window with no one using their system at night, then a full system save is always the best. Is it overkill? Sure, but it will make your restoration easy. Since that isn’t always practical then what I recommend is a monthly GO SAVE 21 which is a Full System Save:
If you don’t have time for that, then do a GO SAVE 22 which backups all the IBM stuff
Either one of these is your basis for recovery. Then each night all you have to backup is backup security data, configuration data, all the user libraries, and user IFS directories. In that order.
Of course, if you don’t have the time or the window each night to do the above, then there is customization you can perform to just backup the libraries that change. This will be a more complicated backup, and a much more complicated restore.
One very important note on Restoration. If you have a fibre connected tape drive, you can’t IPL directly from the tape device. You need to do a D-Mode Manual IPL from your I_BASE_01 CD to load the initial System Licensed Internal Code, and then create your tape drive as an alternative installation device. You will also need to create an alternative installation device on some machines that have an external tape drive and don’t have an HMC. Since we do a restoration a week for different customers, this is easy for us to perform, but you should have these actual steps in your documentation.
Look, the backup is the easy part. The restoration if you don’t know or understand what you are doing is the tough part. Don’t make your first restoration the first time you have to recover your machine. We have machines in our office that you can test your recovery on, and we have machines that we can bring to you to test your recovery on. Our services can range from us doing the recovery and preparing a report to you performing the recovery yourself on one of our machines. In any case, if you haven’t tested recovering your backups, then your backups can’t be depended on !

|Start Journal Library
The Start Journal Library (STRJRNLIB) command introduced in 6.1, and enhanced in 7.1 is a great way to journal an entire library or list of libraries.
Objects created in, move into, or restored into a journaled library may be automatically journaled to the same journal the library is journaled to. Which objects inherit the journal state of the library and what journaling attributes they start journaling with are determined by the inherit journaling attributes of the library. You can’t have an object journaling to more than one journal.
The Inherit Rules parameter can specify different rules for different objects. Remember that these rules only affect objects when they are created, moved into, or restored into the library. The journaling state and journaling attributes of objects within the library do not change if they are renamed.
If the specified library contains a
This is a great command when you want to set up journaling.
|Release levels and PTFs|
People are always asking me how often they should be performing PTF maintenance, and when is the right time to upgrade their operating system. I updated this article from last month with the current levels of PTFs. Let’s look at PTFs. First, PTFs are Program Temporary Fixes that are created by IBM to fix a problem that has occurred or to possibly prevent a problem from occurring. In addition, some times PTFs add new functionality, security, or improve performance. Therefore, I am always dumbfounded as to why customers do not perform PTF maintenance on their machine at least quarterly. If IBM has come out with a fix for your disk drives, why do you want to wait for your disk drive to fail with that problem, only to be told that there is a fix for that problem, and if you had applied the PTF beforehand, you would have averted the problem. Therefore, I think a quarterly PTF maintenance strategy is a smart move. Many of our customers are on our quarterly PTF maintenance program, and that provides them with the peace of mind of knowing their system is up to date on PTFs. Below is a table of the major group PTFs for the last few releases. This is what we are installing for our customers on iTech Solutions Quarterly Maintenance program.
7.1 6.1 V5R4 V5R3
Cumul. Pack 11116 11102 11137 8267
Tech. Refresh 2
Grp Hipers 38 98 161 169
DB Group 10 20 31 24
Java Group 6 17 27 23
Print Group 3 21 44 20
Backup/Recov. 10 23 41 33
Blade/IXA/IXS 7 22 15 –
HTTP 9 21 28 17
TCP/IP 4 12 19 16
Security 8 22 17
The easiest way to check your levels is to issue the command WRKPTFGRP. They should all have a status of installed, and you should be up to the latest for all the above, based upon your release. Now there are more groups than the ones listed above, but these are the general ones that most people require. We can help you know which group PTFs you should be installing on your machine based upon your licensed programs. Here is a nice tidbit. The Cumulative PTF package number is broken down as YDDD, where Y is the year and DDD is the day it was released. Therefore, if we look at the cumulative package for V5R4, the ID is 9104. We can determine that it was created on the 104th day of 2009, which is April 14, 2009. Look at your machine and this will give you a quick indication of just how far out of date in PTFs you may be. I left V5R1 & V5R2 off the list, because if you are on V5R1 or V5R2, you don’t need to be worrying about PTFs, you really need to be upgrading your operating system. The same can be said for V5R3, but there are still customers who are on those releases.
If you have an HMC, you should be running V7R7.3M0 SP1. If your HMC is a C03, then it should stay at V7R3.5 SP3.
For your Flexible Service Processor (FSP) that is inside your Power 5 or Power5+ (520, 515, 525, 550, 570), the code level of the FSP should be 01_SF240_403. Power 6 (940x M15, M25, & M50 machines, and 8203-E4A & 8204-E4A) customers should be running EL350_108. For Power6 (MMA, 560, and 570 machines) your FSP should be at EM350_108. If you have a Power6 595 (9119) then you should be on EH350_108. POWER7 the firmware level is AL730_035 for 8202-E4B (710, 720, 730, 740), AL730_035 for 750 (8233-E8B) & 755 (8236-E8C). Use AM730_035 for 770 (9117-MMB) & 780 (9179-MHB).
