Parallel Costs

While creating a POC of a SQL rewrite recently I received a little surprise as I switched my query from serial execution to parallel execution and saw the optimizer’s estimated cost increase dramatically. I’ll explain why in a moment, but it made me think it might be worth setting up a very simple demonstration of the anomaly. I created a table t1 by copying view all_source – which happened to give me a table with about 100,000 rows and 1117 (more...)

Introduction

A very small number of applications using JRockit R28.2.2 and later may suffer performance issues when compared to earlier versions of R28. In this post, I will describe the issue in detail, and explain how to resolve or work around it.

What Changed in R28.2.2

In JRockit, object finalization requires that each instance of a finalizable class be registered with the JVM at object creation time so that the JVM (more...)

Why is “Dave Unknown” Trying to Social Media With Me?

I know some people share my opinion on this and others totally disagree – but I fail to appreciate why people I have never met, spoken with or care about want to Social Media with me. If we have not met but there is a high probability we share unusual interests then OK, perhaps – but the fact that we both can spell Oracle or know what a gene is does not count as unusual (more...)

Daten “maskieren”: Data Redaction und APEX

Data Redaction, also das Maskieren sensibler Informationen in der Ausgabe, hat wahrscheinlich jeder schon mal gesehen. Sobald man etwas mit einer Kreditkarte bezahlt, sind die letzten oder die ersten Stellen auf dem Beleg durch "X" oder ein "*" ersetzt - einfach, damit kein Unbefugter die Kreditkartennummer sehen kann.

Solche maskierten Ausgaben sind auch für Unternehmensanwendungen immer wieder gefragt. Sei es das Geburtsdatum, die private Anschrift oder die Personalnummer - viele dieser Informationen dürfen für (more...)

APPEND and PARALLEL

APPEND hint in oracle is very useful, there are many benefits

Fragmented data loading – data will clustered above the HWM so that similar data will be together. Otherwise Oracle will place the records in blocks using PCT_FREE rule

  • No undo will be generated – in large direct path insert will free up large amount of data blocks
  • Less CBC latches (because of no UNDO blocks), less CPU usage
  • Readers need not undo the records, (more...)

OTN APAC 2014 : Auckland – Day 2

My day 2 at the conference started with my analytic functions session. I’m always a bit worried I oversimplify things, but people seem to appreciate it, so perhaps I’m just being paranoid. I’m sure the feedback will let me know. :)

Next I went to Chris Muir‘s session of Developing Web and Mobile Dashboards with Oracle ADF. I had already seen this at the AUSOUG WA event in Perth, but I liked it, so I (more...)
