I finally finished downloading the three Portal and Wireless AS10g
Disks earlier today, together with the two Business Intelligence AS10g
disks and the Business Intelligence Tools disk. Here's how the
installation went.
As with AS10g Release 1, I made sure I had around 20GB of free hard disk
space on my laptop, and with 2GB of RAM this is usually OK. I've got
Windows XP Professional SP2 which officially isn't supported, but as
it's on the laptop anyway I thought I'd give it a go before going
through the process of installing Windows 2000 or Windows 2003. I''ll go
on to it later but the upshot of this is that I've not had any problems.
The first disks I installed were the AS10g Release 2 Portal and Wireless
disks [1,2,3] as I guess (rightly it turns out) that these would contain
the infrastructure install. After unzipping the files to three
directorys (Disk1, Disk2 and Disk3) I ran the installer on Disk 1 and
eventually the install options page came up.

Obviously what's happening here is that these three disks contain two
AS10g tiers; the infrastructure tier, and a mid-tier containing Portal
and Wireless, together with the AS Developer Kits. I selected the
OracleAS Infrastructure Tier and was presented with the following
option:

What we're being given here is the choice of installing the
infrastructure database together with OID, just OID or just the
infrastructure database. I selected the first option (to install both at
the same time) and went on to the next stage of the install.
A couple of steps on a rather scary-looking dialog box came up, asking
me about the service running on port 1521.

I guess what's going on here is that the installer has detected
something listening on 1521 (the regular port for Oracle databases) and
is checking that it's a 10g database - given that the infrastructure
database about to be installed is a 10g 10.1.0.3 database, I know I've
had problems getting 10g databases to automatically register with 9i
listeners, so what's happening here is that the installer is only going
to add the infrastructure database to a 10g listener, which it knows
will go ok.
After a couple more questions to do with OID, the familiar SID and
Service Name screen for the 10g database comes up, which obviously means
we're about to go into the infrastructure database install (10g release
10.1.0.3).

After that it was just a case of naming the infrastructure instance,
setting the password and kicking off the install.

Once this part of the install has completed, you then go through the
configuration stage (which went ok) and then make a note of the URLs and
port numbers that have been assigned.
Now the infrastructure has been installed, the next step is to install
the Portal and Wireless mid-tier, which you do by running the installer
on Disk1 again, and this time select the Oracle Application Server 10g
option.

The Portal install goes through as with earlier releases without any
problems (although a warning comes up that this mid-tier isn't supported
on Windows XP). One issue that did crop up during the setup of the
Portal install was that it wasn't immediately obvious which port number
my OID instance was running on - the two numbers (SSL and Non-SSL)
suggested in the online help didn't work and in the end I had to log on
to the EM Website for the infrastructure instance and retrieve the OID
port number from there (which isn't the end of the world, but everything
so far had been so easy)

After installing the Infrastructure tier and the Portal mid-tier, the
next install was the Business Intelligence mid-tier [1,2]. On earlier
Application Server releases both Portal and Discoverer had been on the
same mid-tier, but now they're separated out - as is Forms and Reports,
which means that if you want Portal, Discoverer and Reports, you've
going to have to install four separate AS10g tiers. First of all a quick
check of Enterprise Manager for the infrastructure and Portal tiers...

and then off with the install. As with the Infrastructure and Portal
installs, the BI install went without any problems.

So now it was time to test out Discoverer Drake. The first thing you
need to do with Drake (if you're going to use the OLAP Option) is to
fire up Enterprise Manager, install the Discoverer Catalog, and
authorise the schemas that will contain data that Discoverer will
analyze.

Then it's just a case of starting up Discoverer Plus, selecting the
Discoverer Plus OLAP Option, logging in and then bringing up Discoverer
Drake.
One point I noted was that, like earlier AS releases, Discoverer by
default doesn't use SSO, so you have to log on twice using your
Discoverer username rather than Discoverer just falling back to the
standard SSO login page. Going into Discoverer Plus OLAP you notice the
new look and feel (compared to the beta) but other than that it's pretty
much as you'd expect.

The total size of the install was 2.38GB for the software, another
1.66GB for the infrastructure database (total of 4.04GB). The start menu
has two entries for each of the tiers (a standard Oracle Home entry, and
a tier control entry) with menu items for starting and stopping each
tier instance

That's it for now, more news as I get to play around with the various
bits more.
