RACs True Value
Likewise, Charlie Garry, senior program director for database research at The META Group Inc., said hes hearing good things about RAC, but scalability isnt one of them. "The stuff Ive heard about RAC is pretty positive," he said in Simsbury, Conn. "In fact, I recommend if youre going with RAC, you might as well go with RAC on Linux, since Linux is [Oracles] strategic platform, so youll get the best support. You want to leverage the true value of RAC. Scalability is not necessarily its strong point. Its strong point is its a great consolidation platform," Garry said. "You can take your existing Oracle instances running on more expensive Sun boxes or IBM or [Hewlett-Packard Co.] boxes and take advantage of more powerful Intel [Inc.] boxes they have nowadays, put it in a single RAC and lower your licensing and hardware costs."Click here for more details on RDBMS market growth in 2003. "Its so new, its basically kind of cutting-edge companies across all sorts of different industries" that are running enterprise databases on Linux, according to Colleen Graham, an analyst at Gartner Dataquest, in Tucson, Ariz. In essence, it requires an enterprise to ask itself if its "willing to go where no one has gone before," she added. That may change, though, what with changes to the Linux kernel that have been back-ported from the 2.6 kernel, Garry noted. "Theyre doing a lot more with I/O handling, synchronous/asynchronous stuff," he said. "A lot of stuff coming is stuff Oracle and IBM themselves have contributed back, initially to the Red Hat [Inc.] edition, but its made its way into the distributions. That makes it easier for databases to run." Oracles Mike Rocha says the Linux kernel is ready to rock and roll. Click here to read the interview. StubHubs with him there. "[Our old] Solaris box was a four-processor box with 4GB of RAM," Kernes said. "That fell well within the limit of Red Hat Linux 2.1 at the time. We felt we could have similar multitasking performance and so forth. "While we were experimenting, Red Hat 2.3 was released with memory enhancements and back-ported to older kernels by Red Hat and Oracle, which allows us to grow our database larger than we could on a single Solaris node." When the time comes, will StubHub be ready to tackle the addition of more nodes to meet its rampant growth? It will have little choice, CEO Fluhr saidlest other sites scalp its ticket growth bonanza away. "As a leader in the ticketing spaceyouve got concerts and college sports, every venue selling 30,000 tickets per show, with 4,000 major venues in the United Statestheres a lot of, lot of tickets," Fluhr said. "Its a big task for the database and for the whole system. For us, its important that our system is able to handle that, and its related to what technologies we choose."

As it is, although interest is running high, merely running Oracle on Linux is still uncharted territory for most enterprises. According to Gartner Inc., RDBMS revenue was about $7 billion in 2003; Linux RDBMS revenue was a puny $300 million slice of that.
