Performance, SOA, PL/SQL, Storage, Identity Management, Humor

Performance

The AMIS Technology blog has an article that warms the heart of performance folks: Logging in JDeveloper 11g/WebLogic Server.  Instrumentation is a wonderful thing.

SOA

Also of interest recently at the AMIS Technology was a SOA article. I have to admit that, for an old core DBA type like me a title like SOA Suite 11g (TP4) - Create Mediator based SCA Composite Application from XSD - write to output file using File Adapter seemed a tad confusing at first. After that I read around in the article and really found I had no clue. But it does look like a handy thing for a SOA developer to muck with.

PL/SQL

Lucas Jellema of AMIS Technology has another great little item (seems like AMIS week at the Infogram, doesn't it?), and this one I even understand, on how to use a global context for sharing small bits of data (something like a global variable stored in the SGA as a context: Oracle Database Cross Session Data Cache - Introducing the Globally Accessible Database Context

Storage 

In his Little Things Doth Crabby Make Part VI. Oracle Database 11g Automatic Storage Management Doesn’t Work. Exadata Requires ASM So Exadata Doesn’t Work. Kevin Closson talks about yet another thing that makes him crabby, and also links to this page of miscellaneous items that have some real gold for serious storage geeks (and collectors of error traps that annoy much better than they actually point out the source of the error). 

Identity Management

In the second of a series of postings on the pithy topic of federated provisioning (wasn't that something the civil service did during the Civil War?),  Nishant Kaushik  at the Talking Identity blog discusses the topic and links to several other bloggers carrying on a multiblog discussion of the matter.

Humor

Slashdot had a nice link recently to the Gallery of Exploding Servers. Good video for those who are tired of all the patching and user complaints. Based on the videos, don't put your data center in the middle of a field. The temptation for geeks in white coats to dynamite them (or light off a natural gas line under them), will simply be too much. Oh, and keep a remote backup for key systems, which is the real point of the piece.
