Many times I am asked how to tailor the initialization parameters for a specific process or user. Essentially the easiest way to set custom initialization parameters for a particular session is to use the ALTER SESSION SET command in a logon trigger keyed to a specific schema or schemas. For example, say we had an application where we wanted to set ...

I recently went on a very nice vacation to Curacao. Before I went on vacation the Oracle 10g Grid Control (10.2.0.2) I had installed on my Laptop for monitoring my home office systems was working. I took my laptop with me to allow offload of pictures from my cameras and to track email while I was away.

Oracle’s Oracle10g requires more memory than was ever required before. If you utilize any of the new features such as automatic storage management (ASM) and automatic shared memory management (ASMM) then you really need to pay attention to what memory is doing in 10g.

I remember reading “Brave New World” when I was in high school, we needn’t mention the year. I was fascinated by the system described in the book that seemed so logical on the surface but needed so many props underneath to keep it going.

I often see DBAs and developers who don’t know the first thing about tuning SQL.

With each new release of a database, be it Oracle or one of their competitors, we hear the cry that this release will make DBAs as we know them obsolete. We hear again and again how this automated feature set or that new GUI interface will automate the DBA job. So far, all of these claims of DBA obsolescence have been for naught, to mis-quote Samual Clements “The reports of the DBAs death are greatly ex ...

When I started working with Oracle in 1990 there weren’t many SQL tuning tools available. At most you had the Oracle supplied tools which allowed you to capture an explain plan and minimal tracing. Most SQL tuning consisted of either encouragin ...
