Are you prepared ? Getting ready for that Fixpack install.

Your not alone.
We've all done it. We've all assumed at some point in our lives that our actions can't possibility have any consequences. Its not always the case though. After all, even that clever bloke wrote a law for it - "To every action there is always an equal and opposite reaction"
So why do so many IT professionals fail to take adequate measures before upgrading their software?
IBM periodically releases Fixpacks for the software that it produces. Probably without exclusion every Fixpack has the potential to going wrong. Very wrong. Take IBM Tivoli Monitoring as an example. Installation of a Fixpack could wipe out a TEMS, or a TEPS. How many angry phone calls are you going to have when your TEP clients are all logged out? Or none of the situations are running or firing? You did do that backup. Didn't you ?
The world is full of people who have laid claim to the knowledge that they accept things can do wrong and preparation is key. Why is installing an ITM Fixpack any different ?
IBM goes through great lengths and significant amount of testing to ensure that data loss is mitigated through installation of a Fixpack. Can you honestly say the same for your procedures ?
Can you work out who said the highlighted quotes (and no searching on Google!)?
There's no easy way to say this. Preparation is hard. Time consuming. And if everything goes according to plan, actually, its redundant. But preparing for what could go wrong will save you hours of work one day. Its often said, "There are two types of people in the world; those that HAVE lost data and those that WILL". I include myself in the former category unfortunately, having lost 1000's of digital photos after a hard drive crash a few years ago. Did I backup ? Of course not - I'm an IT Professional! Needless to say, I bought an external hard drive for backup on the afternoon of that fateful day.
I know periodically spend an hour or so every now and again and make sure that all those photos and videos of the kids growing up, or the puppy chewing my wife's new slippers, are backed up. I know I'll loose data again at some point. But I also know I'm prepared for it.
So the disaster has happened. The phone is hot from all the calls you've been fielding. You need to fix the problem, and like, yesterday. You did a quick and dirty backup of a system - "that will be enough ?" you quietly convince yourself. Except its not, and you know it. Spending time knowing what to backup and save before you need it will reap dividends if (sorry, when) the time comes for it to be called into play.
So you look out of your window now, and hopefully the sun is shining for you. So what actions should you be doing NOW ahead of installing that Fixpack ?
Tivoli Enterprise Monitoring Server (TEMS). I cannot write any advise any better than my colleague John Alvord (round of applause please) wrote in one of his Sitw
Tivoli Enterprise Portal Server (TEPS). You should at least have a copy of the TEPS database. Preferably you should do a backup courtesy of the tools provided by your database vendor, eg DB2's "backup database" command. If not - at least run "mig
Unix/Linux : ./itmcmd execute cq "runscript.sh migrate-export.sh"
Windows : <%CA
Better would be to use the following command to backup your portal server database where DB2 Database for Linux, UNIX, and Windows is the relational database management system of choice.
If your using Derby for an embedded TEPS database solution, then consider following procedure to back up
Warehouse. All that data. Gigabytes of it. Its taken you months, even years to collect it all. You don't want to lose it. Fact is, its highly unlikely that any Fixpack installation could wipe out the Warehouse database. But you should still get the data backed up. Just like the TEPS, on DB2, the command is
db2 backup database your
If an existing connection prevents you from backing up the database, use the following commands.
As I said, IBM places a huge amount of resources into ensuring the quality of the Fixpacks that we release to customers. The fact is, that we can't control every step of every process of the Fixpack install. Hard drive failure, power outage, network blip, user error. The little blighters waiting to strike when your not expecting them.
But you are expecting them now. Aren't you. Your PREPARED.
