DBMS_SCHEDULER jobs running an hour late – DST/BST issues!

This week one of our developers highlighted the fact that the DBMS_SCHEDULER on one of our 11.2.0.3 databases was running jobs an hour later than scheduled until just recently, when the clocks went back (26/10/2014) for British Summer Time (BST) …and now they’re running on-time again! I’d not seen this before, and at first I thought we

PeopleSoft’s paths to the Cloud – Part II

In my previous blog post, I've covered some ways in which cloud computing features could be used with PeopleSoft, particularly around Infrastructure as a Service (IaaS) and non-Production environments. Now, I'm going to discuss how cloud technologies bring value to PeopleSoft Production environments.

Gain Flexibility



Some of the advantages of hosting PeopleSoft Production environments using an IaaS provider were also mentioned in the my past article as they are also valid (more...)

Mount ASM diskgroups with new ASM instance

Imagine you have 11gR2 Oracle Restart configuration with database files located in ASM.

After server crash you realized that local disks are corrupted and with local disks you lost all Oracle installations. Even though this is important system you don’t have database backup (always take backups!).

But you managed to save all ASM disks as they were located on separate storage.


This will be small beginner guide on how to help yourself in such (more...)

Oracle Trivia Quiz

All the answers can be found in the November 2014 issue of the NoCOUG Journal. Which executive vice-president of product development at Oracle began as the PL/SQL product manager? (page 23) Which senior vice-president of server technologies at Oracle wrote the B-Tree indexing code back in the day? (page 23) What is the evil twin […]

Results of the NoCOUG SQL Mini-Challenge

As published in the November 2014 issue of the NoCOUG Journal The inventor of the relational model, Dr. Edgar Codd, was of the opinion that “[r]equesting data by its properties is far more natural than devising a particular algorithm or sequence of operations for its retrieval. Thus, a calculus-oriented language provides a good target language […]

We Have a Winner!

Kim Berg Hansen from Denmark wins the SQL mini-challenge for his UNION ALL materialized view with fast refresh on commit. An analysis of his solution has been published in the NoCOUG Journal. Judge’s statement: “Kim won on participation, efficiency, and accuracy. He kept submitting refinements, lowering the bar until he reached the theoretical lower limit of 1. His solutions survived the test cases written by the judging committee.”


PeopleSoft’s paths to the Cloud – Part I


Nowadays, all paths seem to lead to cloud computing. In the business applications world, Oracle is pushing hard to position the Oracle Cloud Applications in an increasingly competitive market. The reasons that favor Software as a Service (SaaS) applications over their on premise counterparties are significant, even though there are still a good number of circumstances under which the latter should normally be the preferred option.

Dead Code Kills

Your applications contain 20-30% dead code that is never executed. Not just commented-out code that programmers have left in “just in case”, but routines never called, branches never executed and screens never displayed.

The cost of software maintenance depends on the size of the code base, but systems with dead code are more expensive to maintain. This is because every time a developer comes across a dead piece of code, he becomes unsure: “I wonder (more...)

APEX Tabular Forms Deep Dive at #ORCLAPEX NYC Meetup

Ever heard of APEX$ROW_NUM, APEX$ROW_SELECTOR and APEX$ROW_STATUS? Did you know you can reference tabular form columns using bind variable syntax in your page processes? Are you familiar with the execution scope of tabular form proecesses for modified vs submitted rows? Ever struggled using apex_application.g_fxx arrays with checkboxes?

OCP 12C – Resource Manager and Performance Enhancements

Use Resource Manager for a CDB and a PDB Managing Resources between PDBs The Resource Manager uses Shares ans Utilization limit to manage resources allocated to PDBs.

PeopleTools 8.54 Feature: ExcelToCI Errors and Warnings Worksheet

Some years ago, I wrote this post on ExcelToCI limitations. One of the limitations I've found annoying in the past was the need to move the mouse over each Warning or Error result cell. It was not just annoying, it actually didn't allow the users to easily work on the different error types and analyze useful information such as the most common error messages, how many rows would go through if they solved a particular (more...)

Increase disk space for VM running Linux

When I create virtual machines on my notebook I always create too small disk for root partition or partition where I put Oracle binaries. After a while when I want to perform upgrade, or install another Oracle software, there is not enough space. This time I want to note steps about how to increase disk free space.

I can easily extend or shrink my logical volumes because I am using LVM in my virtual machines. (more...)

Find block in ASM

In the post Where is my data I have shown how to locate and extract a data block from ASM. To make things easier, I have now created a Perl script find_block.pl that automates the process - you provide the datafile name and the block number, and the script generates the command to extract the data block from ASM.

find_block.pl

The find_block.pl is a Perl script that construct the dd or the (more...)
