Flashback, Blogs, Escalation, Complexity, APEX and RAC, Uptime/Downtime

Flashback

Flashback database is one of those dream features for the DBA - just roll back time and make the waves of people recede from your desk. But it's not a perfect world, even for the Oracle DBA, so read through some of the pitfalls and tips from H.Tonguç Yılmaz in this blog posting.

Some New Blogs

Just an echo from Jonathan Lewis, but if he likes them, these blogs are likely to be in the good to awesome category:

ASH Masters (Kyle Hailey, Graham Wood, John Beresniewicz)

Tanel Poder (who I frequently link to from here)

Alberto Dell'Era (whose blog links show a definite Oak Table flavor).

Escalation

Escalation is a key part of the SDM job. Chris Warticki posted this some time ago, and it bears reading. One of the best complements I ever received for my company was when a customer was talking about a non-Oracle problem and said: "Boy, I wish (vendor name censored) had support like you guys". Yes, we have our good and bad days, but overall Oracle Support is a really impressive device for problem solving.

Complexity

Gavin Parish is starting a discussion on complexity and, since his description of how to arrive at a complex Oracle system sounds very much like a description of one of my customer's architecture I thought some of our readers might like to get involved in Gavin's discussion.

EBS and JDeveloper

A couple of good postings of late at the In Depth Apps blog:

BI Publisher: How do I replace linefeeds, newline or carriage return whitespace / special characters

and

Find JDeveloper with OA Extension patch for Oracle eBusiness Suite Release 11i CU1 CU2 RUP3 RUP4 RUP5 RUP6 R12.0.0 12.0.1 12.0.2 12.0.3 12.0.4

APEX and RAC

Simple, powerful applications on HA steroids. David Peake points out a white paper on running APEX on RAC.

Uptime

Gaurav Verma has a handy script for mining the alert log to determine uptime (and the painful alternative, downtime) from your Oracle RDBMS.
