My former colleague in Chicago Richard complains that I haven’t updated this blog in a while.  To help him steal ideas from me and tell his boss he thought them up, I figured I’d post a few miscellaneous new things.

Broken Record

I’ve been sounding like a broken record, in that whenever I went into My Oracle Support (you know, the slow version of what used to be Metalink?) I’d have to log out and log back into their non-flash site to upload files because it didn’t work with Chrome.  Well I don’t know whether it was an update to Chrome or MOS, but you can finally upload all the inane logs and output file your analyst asks you for while in Chrome!

Chrome is not a crime!

While we’re on that subject

Some evidence all my whining about Oracle’s lack of support for Chrome may have merit!  I noticed this on Slashdot today, and, in a nutshell, it says Chrome will overtake Firefox as the #2 browser within the next few months, and IE is taking huge losses to Chrome as well.  I despise IE, avoid it like the plague (virus?) that it is, and will not shed a tear when it finally falls from the top spot.  It all goes back to the way Micro$oft forced IE down our throats, and I will not browse with a known monopolist.

EM 11g from an iPhone

I found another reason my iPhone runs circles around my old Blackberry.  With it’s built-in VPN capabilities, I can actually get to my EM 11g web server and, well, work!  The only exception is, of course, the well publicized lack of flash support for iOS, noted in the screenshot of the performance tab in the database.  If anyone from Oracle is watching… any chance we can get off flash (HTML5?) in some future version so there’s full mobile functionality?  If not, how about an EM Grid Control App?

These are unedited screenshots from the iPhone, except where I had to hide IP addresses and the like.

Making the Oracle 11gR2 client install on Ubuntu 10.04 LTS

Filed under: 11g, Ubuntu — kkempf @ 3:21 pm

A Fresh Start

I recently had to reload my work notebook so it would dual-boot Windows 7 or Ubuntu 10.04 (instead of the old configuration, where Windows 7 ran inside Ubuntu via Virtual Box). As a result, I lost my tried and true Oracle client install on Ubuntu, and had to go about it from scratch again. Officially, like so many things I post about, this is totally unsupported. Realistically, I’ve been using the 11gR2 client on Ubuntu for years without incident. It’s nice to be able to right click to open a terminal session, then sqlplus apps@prod to get into my database.

Just Get to the Good Stuff!

I think I hit every possible trap going through this install; I’m going to spell them all out (as opposed to just saying “Install this package, create these links, and edit your profile this way…”) so that if anyone Googles the error messages, they might find the solution here.

First Point of Failure: Packages

I knew it wasn’t going to work without some manipulation, but I wanted to see what the errors looked like. Of course, the installer says a bazillion packages are not right, and I checked ignore all. In most cases, Ubuntu 10.04 has advanced versions of these packages, so it’s not that they’re not there, it’s just that the installer isn’t seeing the version it wants. That’s not true in the case of AOI access libraries.

The failure looks like this:

The installer chokes...

The install log provides some detail

Ensure aio-dev libraries are installed via the Ubuntu Software Center

Second Point of Failure: Symbolic Links

Without a few symbolic links, you will a mysterious error similar to this in the next in the installer when it tries to link binaries:

Ah, the mysterious nnfyboot and error!

If you see this, create the following symbolic links as root:

ln -s /usr/bin/basename /bin/basename
ln -s /usr/bin/awk /bin/awk
ln -s /lib/ /lib/

ln ­-s $ORACLE_HOME/lib/ $ORACLE_HOME/lib/

Third Point of Failure: Environment

This is a little murkier, as I’m not sure if I was fighting symbolic links and the environment, but ultimately you need this in your profile anyways.  So if you’re still having problems, use vi or append to /etc/profile the following lines and rerun the installer:

export ORACLE_HOME=/home/kkempf/Oracle/product/11.2.0/client_1


No install is complete without!


After (embarrassingly) realizing I forgot my tnsnames.ora file in $OH/network/admin, sqlplus fired up just fine:
