Bind peeking and session cached cursor

Bind peeking is a nice feature in Oracle to have many optimized plans for an SQL for various bind values.  DBAs believe that bind peeking happens during a soft parse which will identify an alternate plan. Why do I say that?

 

Hard Parse: Parsing first time, nothing exists to bind peek

 

Soft Parse :  SQL cursor is existing and executing not the first time.  Under the soft parse, bind peeking (more...)

SQLcl Commands: Info & Info+ – The New DESC?

We put out a HUGE update for our new SQL*Plus-style command line interface for Oracle Database.

In a recent blog post Eric D. Brown defined an Agile Data Center as

An Agile Data Center is one that allows organizations to efficiently and effectively add, remove and change services at the speed of the business, not the speed of technology - Eric D. Brown

In follow up post he said that a Agile Data Center could be implemented by Software Defined Data Center (SDDC) for example using machine (more...)

Friday Spotlight: Powering a Demanding Enterprise Operation with Oracle VM

| Jan 30, 2015

Much like Oracle’s customer base (some 400,000 companies in 145 countries), Oracle deploys Oracle database, middleware, and application products to support its day-to-day business operations. By virtualizing enterprise applications using Oracle VM, Oracle’s IT organizations realize greater flexibility and lower infrastructure costs. Instead of implementing physical machines for each required operating system version and application release, virtualization using Oracle VM consolidates servers and provides efficiencies that help to decrease capital (CAPEX) and operating expenses (OPEX).

Essbase BSO Parallel Calculation and Calculator Cache

Essbase BSO parallel calculation utilizes calculator cache on a per thread basis. This post is to show the relationship between using parallel calculation and calculator cache.

For calc parallel and calculator (calc) cache:

  • Calc Parallel specifies the number of threads per calculation execution

Finding zero values in an array

| Jan 30, 2015

A common thing to want to do is to find zero values in an array. This is obviously necessary for string length. So we'll start out with a test harness and a simple implementation:

#include "timing.h"

unsigned int len(char* array)
{
  unsigned int length = 0;
  while( array[length] ) { length++; }
  return length;
}

#define COUNT 100000
void main()
{
  char array[ COUNT ];
  for (int i=1; i<COUNT; i++)
  {
    array[i-1] = 'a';
     (more...)

GlassFish 4 Command Line 101

| Jan 30, 2015

At it's heart Java EE is a standard API and SPI for developing applications that are deployed to an application server runtime. Though some people miss this point most application servers like WebLogic and GlassFish are far more than vessels for applications. Application servers also typically provide a rich set of features geared towards scalability, security, systems integration, optimization, diagnostics, management and monitoring. The GlassFish command line interface (CLI) is a great example of just (more...)
