Hello and welcome to the SAP HANA Academy.
The topic of this video tutorial series is SAP HANA platform Installation and Update
and in this video we will discuss updating an SAP HANA system.
Hi, I am Denys van Kempen.
In most cases, updating SAP HANA systems will be an automated affair, using the command
line installer, hdblcm, with parameter files and maintenance scripts.
However, for those situations, where you want to perform a one-off update, we can also use
the graphical installer (for Windows), or the web interface.
Here we have SAP HANA Lifecycle Management, in graphical disguise - all three versions
pretty much work the same way - First, select the component location - depending
how you start the installer, it might have already detected the installation kit - then
either go for an update, or a new install - that’s the activity - should you have more
systems you want to update, you can indicate that here, then, select the components you
want to update by default, all installed components will be selected and you could, optionally,
add new components to your system at this stage, maybe add Smart Data Access, or an
Application Function Library. Enter the password for the operating system administration account
(+adm) and the password for the database administration account, should you have disabled
the SYSTEM user and want to use another user, you can specify that here as well.
In case the XS advanced runtime is also installed, you need to provide the credentials here,
user name, password and organization name for the SAP space, and select the XSA components
you want to update or install - the default selection is a bit more inclusive, as you can see.
Finally, we get an overview screen that lists all our selections for review.
System T01 is not running, so the installer informs us that it cannot verify and check.
I will cancel for now, start the system up and switch to the web installer.
OK.
The system is coming up.
Here we have SAP HANA Platform Lifecyle Management, web interface.
Offers a bit more functionality, we can download components directly from SAP ONE Software
Downloads, we can create a distributed system by adding a host, or in case we are already
running with multiple hosts, add more hosts to scale out.
We can add or remove host roles, configure system landscape directory registration, and so on.
There are videos on most of these topics in the SAP HANA installation and update or the
administration playlist.
In this video, we are going to update our system,
so I will select Update System and Components.
Like before, we are prompted to select the component location, here labeled Installation Kit.
Now, what’s different from the Windows version we just saw, and what’s new in SAP HANA 2.0 SPS 03,
is that by default, the authenticity of the installation kit will be verified.
In fact, the URL points to the SAP Host Agent which has loaded the resident lifecycle manager for us.
The resident lifecycle manager is trusted, so it can perform software verification for us.
The installer that comes with the installation kit is not trusted, by default
who knows where it may have been?
so you would need to verify it yourself using SAPCAR, for example, and then run hdblcm with
the software_verification=on flag, in case you want lifecycle manager to perform software verification.
Here on the web, this comes out-of-the-box, so let’s Proceed with Update.
Please wait.
Verifying authenticity of the installation kit.
This may take up to 5 minutes.
Well, it only took about 30 seconds on my system, your mileage may vary.
The full installation kit is about 13 gigabytes.
Then, we get our list of detected components.
This is what we can install.
Should we want to install more, we can add additional Software Locations here.
We also have the option here to make changes to the installer configuration.
We could select just to perform the checks but not to update, in case of a test run.
Maybe skip certain checks, there are SAP Notes on this that explain the context.
We can change the update execution mode.
In case you are installing additional components, like Dynamic Tiering, for example, the installer
can bundle the restarts, so it only happens once.
Depending on the component you install, a restart may be required and his way, you can
prevent multiple restarts, which always take a bit of time.
Then, there are different settings for the database client, the plugins, studio, and
the XS Advanced Runtime.
OK - Next
As before, now we need to select the components we want to update or install on our system T01.
Installed components are selected for update automatically.
On my system, that’s the database client and the XS advanced Runtime.
That’s fine.
Next.
hdblcm will now also verify the individual components for us.
Only takes a couple of seconds and then we get the authorization screen: passwords for
the operating system and database administration accounts.
Next.
Input is checked same for the XS Advanced Runtime.
Then we can choose with XS Advanced components we want to install or update.
You get this screen only, of course, if XSA is installed.
I will not make any changes here.
We will look into the SAP Enterprise Architecture Designer for SAP HANA, some other time.
Next - Review and Confirm Entered Data.
Software Components, XS Advanced.
Looking good.
Off we go.
Update - First the packages are extracted on the file
system, upzipping basically.
I will fast forward through these screens here.
I know you are busy.
Then the system is stopped Files are updated and the system is started
again.
This goes all pretty quick, couple of minutes.
Updating the XS advanced runtime, however, will take a bit more.
About an hour, maybe.
Fast forward
and our system is updated.

Close to exit.
Easy does it.
That’s it.
