The Sybase market had almost close to hitting the Rock bottom. Sybase is still thriving because of its federal contracts. As so some of the other prime dbs, "Ingress", and "Informnix". DB2 is thriving because it had taken control of Informix, and its an another story of compac slashing Digital. The wall street does use oracle, its that not every body get the opportunity to be hired by them. Citi Bank uses oracle. I have also heard that NYSE too uses oracle, and their servers are all located somewhere in verginia or so.

One word - COST.
Recent case history for a company: ORACLE 12 million, DB2 2 million.

Recently in a conference I was standing amongst a group of DBA's from various companies who were discussing the same topic as this post and one of them said that sybase is very good in handling IO's and since there are millions of small transactions in the financial industries it was the first choice because of the performance.
He did not substantiate his claim though and i wanted to through it out here for comments.

See first they start using Sybase, So all there apps, etc. are
prepared for Sybase. at this stage no body is going to move to
different db because it is working fine. It is very difficult for them to do changes. It doesn't mean that oracle is not fit for finincal ind. I am seeing the lot of telco OLTP database running on Oracle.

Our financial application is installed in banks worldwide (approx 100 banks).
Looking on our clients ( banks ) the approach is as follows:
Mainframe - DB2
UNIX - ORACLE8, ORACLE8i
NT (small banks) - ORACLE and MSSQL
so from my point of view the reason is the platform and existing background in banks.

Here is somebody who doesn't have a firm grasp of versions past 7.x. Of the 31 points, 5 are valid beefs, 15 are simply untrue, and 11 are due to lack of knowlege.

I didn't even see the second page. 32-46 follow approximately the same distribution.

That shows the persons knowlege of the IT requirements!!!, Most of the times you would want to give some permissions and restrict others, so the privileges are of security concerns. Oracle had implemented them long time since, now only other vendors are realising of their needs. So I would agree with Jeff.
Now comming to the point of giving my opinion on the Infoweek, I would think that it was kind of a biased one. I have seen reports and stats showing the market values of Oracle to be the higest when compared to DB2. I would also consider the report to be kind of obsolete, appart from agreeing to its pricing flaws. But again, if you want a good reliable product, you do require to pay the price. Most of the people from other areas doesn't seem to like oracle, because, it requires the novality to manage them, i.e. its not of the order of point and click, SHAZAM!, things are done!. I really like oracle because of its tunability. Most other vendors to my knowledge have scavenged the features from oracle, but so does the oracle too.
The database comparison the article had done used 8.1.5 which I do agree to an extent was not stable. But the later ones were pretty stable. One other thing that people tend to like DB2 was not alone for the DB, but for the bundle of applications that they would get with it for free.

With Oracle's high price and difficult manageability and also with a lot of people out there not liking oracle as sam said how do you go about convincing your management to use Oracle.
Why would somebody invest 2-3 times more money in oracle and also get the headache of hiring expensive DBA's .
The line seperating Oracle and DB2 is very thin now and is getting thinner day by day and the real sale men of oracle products are the thousands of DBA's whose bread and butter is oracle rather than Oracle's sales team.
Also Oracle's financial results have reflected their not so good performance.
