In-Depth: Thoughts on Testing from a Battle-Scarred Support Engineer

Steven Chan - Mon, 2011-01-24 15:05
"The more I practice, the luckier I seem to get." "If you think safety is expensive, just try having an accident." The two quotes above I think pretty accurately sum up the importance of preparation and planning. The first has been attributed to various professional golfers over the years and suggests luck is never accidental. If things work, they work for a reason and that reason is usually because of good preparation, not good luck. The second quote has been attributed to various airline industry executives. Here the message is that however much time, and inevitably money, that you spend making sure your planes do not crash, it will cost you considerably more if one of them does. The real message is of course that planning and preparation pay off in the long term and, in the context of your Oracle Applications upgrade, you can conclude that successful upgrades are the result of good testing, not good fortune. This article is just a few thoughts from a battle-scarred Support Engineer on why good testing is crucial to the success of your system and why it is important for you to thoroughly test any patches, upgrades or migrations before carrying out the work on your production environment. The great majority of the work that you do in any project will be testing. Underestimate it at your peril. Testing is not simply a necessary evil which has to be endured before the inevitable, white-knuckle ride of the production upgrade. Testing is not where you should be cutting corners. Testing is where you should be going into every conceivable corner you can find and looking for something that might, without warning, jump out of the shadows and derail your production upgrade.

Upgrading EBS 12 to DB 11g with Physical Standby Enabled

Steven Chan - Fri, 2011-01-21 17:08
It's possible to use Oracle Data Guard to create physical standby databases for disaster recovery. E-Business Suite users can configure their environments with the latest version of Oracle Data Guard 11g by following the documents linked in this article: * Business Continuity for EBS Using Oracle 11g Physical Standby DB When upgrading a database to a new release, you can upgrade the Data Guard Physical Standby database inline to minimize the downtime. To achieve this in an EBS 12 environment, additional manual configuration steps are needed on both the primary and standby systems. These manual steps allow redo to be shipped from the primary and applied on the standby during the upgrade. Sreelatha Doma

Experienced Apps DBAs know that they need to monitor database support windows for their E-Business Suite environments.

Top 10 Reasons to Develop in a VM

Jeff Kemp - Mon, 2010-08-30 01:00
The cost of providing Virtual Machines to all your developers can be quite high, especially in terms of initially setting it all up (e.g. a typical developer may require two VMs running concurrently, one for the database server, one for the app server; their desktops will require enough grunt to run these while they also [...]

Generate DML/DDL/QUERY from SQL – the easy way

Jeff Kemp - Wed, 2010-08-25 21:00
This is a comment on’s article “Generate DML/DDL/QUERY from SQL” – comments are not enabled on their blog so here’s my addendum. The following query is offered as a means of generating a script to ONLINE all datafiles in a database: select 'ALTER DATABASE DATAFILE '''|| name || ''' online ;' from v$datafile; I [...]

InSync10 Day 2

Jeff Kemp - Wed, 2010-08-18 08:00
Another good day in Melbourne. Heard Richard Foote talk about Indexing New Features in Oracle 11g release 1 and 2. One thing he demonstrated was the creation of an index on only part of a table – normally I’d use a function-based index for this sort of thing, but his technique results in an index [...]

Never satisfied

Jeff Kemp - Wed, 2010-08-18 03:00
So I followed the great advice here to use the new COLLECT function in Oracle 10g to solve the common string-aggregation-in-SQL problem. I chose this solution over the others because it sorts the results as well, which was a user requirement. This is because the COLLECT function optionally takes an ORDER BY clause – even [...]

InSync10 Day 1

Jeff Kemp - Mon, 2010-08-16 05:00
After a scrumptious breakfast at the Armoury I headed in what I believed was the general direction of the Melbourne Convention Centre – after making a wrong turn I eventually spotted a footbridge over the river that rung a bell from my GoogleEarthing; after taking some photos I was finally at InSync10. The first session [...]

Editing Oracle Reports

Jeff Kemp - Wed, 2010-08-11 01:00
If you’re like me, the above picture will probably have given you a frisson of dread. Just a little. The example here is not a very complicated report, just a few repeating groups based on quite a nice data model. What catches me every time, however, is a few little apparent quirks in Oracle Reports [...]

Directory File List in PL/SQL

Jeff Kemp - Tue, 2010-08-10 01:00
UTL_FILE, unfortunately, does not allow you to query the contents of a directory. One option is to create a java routine. Note: this is not my code – a colleague sent the basics to me and I’ve just modified it somewhat to suit my purpose. CREATE OR REPLACE AND RESOLVE JAVA SOURCE NAMED "DirectoryLister" AS [...]

Purge all Recyclebins without SYSDBA

Jeff Kemp - Mon, 2010-08-09 01:00
Want to purge all the recyclebins for all users in your database? Can’t (or don’t want to) log in as each user individually to run this, one by one: PURGE RECYCLEBIN You could log in as SYSDBA and run: PURGE DBA_RECYCLEBIN But, what if you don’t have SYSDBA access? (Yes, this has happened to me, with [...]

In Oracle, ” = NULL but NULL != ”

Jeff Kemp - Wed, 2010-08-04 19:00
When I get the result of my PL/SQL quiz for the day, I’m pleased when I got it right, but if I got it wrong, I’m either annoyed or overjoyed: If I disagreed with the result, I’m annoyed. If I agreed with the result, I’m overjoyed – because I learned something new, or I was [...]

Tag wikis on StackOverflow

Jeff Kemp - Mon, 2010-08-02 01:00
StackOverflow now allows the creation of wiki articles and tag synonyms. I’ve gone ahead and started a few articles about a few topics dear to my heart: oracle plsql apex – synonyms: htmldb and application-express These articles are not intended to be replacements for the documentation or Wikipedia, but primarily as a guide for people [...]

The Templating Way

Jeff Kemp - Thu, 2010-07-29 18:00
Today, grasshopper, you will learn the Way of the Template. The Templating Way is the path by which complex output is produced in a harmonious fashion. The Templating Way does not cobble a string together from bits and pieces in linear fashion. htp.p('<HTML><HEAD><TITLE>'||:title ||'</TITLE></HEAD><BODY>' ||:body||'</BODY></HTML>'); The Templating Way separates the Template from the Substitutions; by this [...]

A fascinating SQL problem

Jeff Kemp - Thu, 2010-07-29 00:00
Can you solve this problem in SQL – i.e. without resorting to a procedural solution? SQL combine multiple identifiers to create a group id for duplicate records “I have a data extract with three different identifiers: A, B, C Each identifier may appear in more than one row, and each row may have one or [...]
