Whether its company flaks, the media or users, everybodys talking about the forthcoming 10g products from Oracle. With Oracle Application Server 10g already out and Oracle Database 10g on the threshold of release, I turned to the International Oracle Users Group to get an update on what early users like and dont like in the new products.
For her part, IOUG President Kim Floss, a database expert who works in the food manufacturing industry, is a self-described tuning nut and is looking forward to diving into 10gs automated SQL tuning. “[Tuning is] a personal passion of mine,” she said. “Any new tools and features Oracle comes out with to make my job easier, Im excited to get out and play with.”
Normally, when Floss goes through a tuning exercise, she evaluates a boatload of alternatives using manual analysis to work through the proof output. With 10gs new automated SQL tuning features, much of that will be delivered to her in a report.

Tuning aficionados will appreciate the significance of automating this work. In previous DBA jobs, Floss said, she has regularly been in situations where a business will try to close its books at months end or years end. The financial side of the house needs to analyze certain reports to get that work done, and it makes a big difference if those reports come out in three days or in 10, or even in 10 minutes versus one minute.
The lineup of sessions in the IOUGs upcoming conference, IOUG Live! 2004, reflect the fact that the IOUGs members share Floss preoccupation with tuning and code optimization.

Thrilling Application Server 10g
For her part, Kelly Cox, an IOUG board member, has been putting Oracle Application Server 10g through its paces. Cox said shes “thrilled” with the new version, which she installed in a fraction of the time shes spent on prior releases.
“I was able to complete the install in about 5 hours, which is unheard of in prior releases,” she said. “Ive never completed an install in less than two or three days.”
Cox, a consultant, said that the small to medium-sized businesses that form her client base will benefit both from the ease of installation and the vastly improved documentation with which 10g ships. Documentation in previous releases seemed to assume that a given user is familiar with Oracle prompts and has a general, pre-existing sense of the product, Cox said.
“For people who are new to the Oracle world, it hasnt been that easy to contend with,” she said. “But Application Server 10g documentation really explains concepts well. It doesnt let you get into the installation part before reviewing what youre doing, and thats just wonderful.”
In addition, Application Server organization has been streamlined, Cox said, and offers much more flexibility. She offered one example: In 9i Release 2, a repository of database structures that support Application Server had to be installed into the applications own database and was very difficult to install into a customers own database.
Unfortunately, putting the metadata repository into their own database is exactly what most customers want, since its much easier to access ones own data to display in a portal, for example.
Another reason a customer might want to install the metadata repository into another database is when deploying a clustered or grid environment. In such a case, metadata must be stored in whatever database has already been configured, Cox said.
With 10g, the choice of putting the repository into an external database is built-in and documented. Thats important not only because its easier to work with your own database but also because most shops have a defined set of databases that their DBAs are in charge of administering. Being powerless against having a new database introduced was not something such shops appreciated, to put it mildly.

Better flexibility in AS

Another flexibility in Application Server 10g is the power to control port numbers and host names. In earlier releases, once installed, host names or port numbers couldnt be changed. This becomes an important issue when moving from development to production.
Usually, when people install, they do so on a test set of systems, in order to work out how the application will be configured. Choice of port numbers is also an issue for those organizations that have standards regarding what port numbers to use for which types of applications. “Without that flexibility, youre real limited and you cant keep to your own standards,” Cox pointed out.
Enough of the accolades. Was there anything these IOUG members didnt like about 10g? Anything that Oracle still needs to work on? Nope, they said. For now, Cox and Floss are happy with their 10g trials. “My wish list has been answered,” Cox said.
Merry Christmas, indeed.
