Virtual Development Server: Add swapfile to VirtualBox as requirement for installing Oracle or build Oracle docker images

As I want later build Oracle docker images, some of this need a swapfile.

Per default my used Vagrantbox, does not have one, so later steps will fail.

As in the last blog I use a Vagrant shell provider.

...
  # add swapfile to the box
  config.vm.provision :shell, :path => "add_swap.sh"
...

This calls the script add_swap.sh in the created VirtualBox machine.
Make sure, that you create your swapfile on a supported (more...)

Node.js tutorial part 1; setting up your environment

In a previous post I explained what Node.js is and how it works. Now, I’ll help you install it and create your first Node.js powered webpage.

I make the assumption you have some basic HTML and Javascript knowledge.

Node.js is installed as part of the npm installation. npm is a very powerful Javascript package manager that will save you tons of work when used properly. We at Whitehorses do not suffer from the “not invented here” (more...)

Real Push Button Refresh with Raspberry Pi

Push Button

In this post, we’re going to perform a push button refresh of an Oracle Database, Application Express (APEX) installation, and Tomcat webserver.

“But Oracle Alchemist,” you’re probably thinking, “we know about that. You’ve told us about how Delphix can provision and refresh data.” And yes, you’d be right. But I wasn’t done yet.

We’re going to perform a refresh of an Oracle Database, APEX installation, and Tomcat running in Amazon Web Services, replicated from (more...)

Deploying Application Express with Delphix

VDBs

Seamless cloning of an application stack is an outstanding goal. Seamless cloning of an application stack including the full production database, application server, and webserver in a few minutes with next to zero disk space used or configuration required is the best goal since Alexander Graham Bell decided he wanted a better way tell Mr. Watson to “come here.”

So in the spirit of discovery, I’ve installed Oracle REST Data Services (ORDS) 2.0 (more...)

Another Great OpenWorld

Steve at the Delphix Booth

Last week I attended Oracle OpenWorld 2014, and it was an outstanding event filled with great people, awesome sessions, and a few outstanding notable experiences.

Personally I thought the messaging behind the conference itself wasn’t as amazing and upbeat as OpenWorld 2013, but that’s almost to be expected. Last year there was a ton of buzz around the introduction of Oracle 12c, Big Data was a buzzword that people were totally excited (more...)

Oracle OpenWorld

Are you going to Oracle OpenWorld 2014? I am, and I hope to see you there! As you probably know, OpenWorld is a humongous event with tens of thousands of people in attendance and some amazing presentations. Why, I even hear Oracle’s new CTO might be there. I wonder if he has anything to talk about?

This year we’ll have a ton of activity at the Delphix booth. You can check out the speaking schedule, (more...)

Frequently Misused Metrics in Oracle

Lying Businessman

Back in March of last year I wrote an article on the five frequently misused metrics in Oracle: These Aren’t the Metrics You’re Looking For.

To sum up, my five picks for the most misused metrics were:

Business Graph

  1. db file scattered read – Scattered reads aren’t always full table scans, and they’re certainly not always bad.
  2. Parse to Execute Ratio – This is not a metric that shows how often you’re hard parsing, no matter how (more...)

Same mistake, three different errors…

Funny thing I had today. Well funny, not when you want to make progress in your work, but still interesting what I discovered when I tried to isolate the problem…I found a way to make the same mistake and have Oracle return three different errors, dependent on the order of (more...)

Oracle BI Publisher Desktop Microsoft Visual Basic System Error &H8000FFFF -2147418113 Catastrophic failure

Conditional Unique Indexes

One way to find that ORA-942 causing missing grant

Uncategorized
| Jan 30, 2013

Hi all,

It has been too long since the last post. It is not that I do not want to, it is just way too busy…

I just came across a small problem where a .NET application written by someone else caused an ugly Stack trace with a ORA-942 (Table or View does not exist) after being moved to the next environment. The error was not there on development, so they asked me what the problem could be. At first I did my compare of grants to the Role I am supposed to use for the application. The problem is (more...)

R12 E-Business Suite Suppliers Query – SQL to join Suppliers, Contacts, Banks

In the Oracle E-Business Suite (EBS) Release 12 the data model of Suppliers has become much more complex. The base tables have changed (Suppliers, Sites, Bank Accounts, Contacts) and some of the fields have become obsolete.

Here is a query to bring many of the Supplier attributes together, with focus on banks / bank accounts, payment methods, contacts, remittance delivery (email, notification method). Please post comments if you find any issues!

Adjust the WHERE clause on the first WITH query to return the suppliers that you need to report on. Hope this query helps someone out.

Add additional fields to (more...)

Track and Trace E-Business Suite Concurrent Request – EBS Logs, O/S Process IDs, Locks

I often get asked to take a look at an Oracle eBusiness Suite concurrent request to see what it is doing, this can come from a few different angles:

  1. What requests are currently running?
  2. I have an operating system process that is taking too much CPU - what is it doing?
  3. Can you tell me where the request is at? I've clicked on the log but it doesn't show anything!
  4. My request is taking too long - can you check for blocking locks?

There are a number of strategies to track and trace where things are at for a running (more...)

How to deal with DBMS_RLS?

 

These last weeks I am trying to get the VPD option (Virtual Private Database) enabled for my application. This time as a developer with no DBA or SYS privileges. I am used to being a DBA for the databases I work on and am used to being able to get the fullest out of the Oracle database. For one, because I think Oracle provides us with a great deal of built-in features that do things more efficiently than we can do ourselves (more efficient, built-in kernel code) and also especially because it seems useless (more...)

EBS Bursting: Filter on XML Elements using XPATH in Bursting Control File

Just a quick post to give an example of a bursting control file that has multiple emails, with a filter based on XML Element in the data to select which email to send.

Environment Variables from database table – Oracle E-Business Suite

Are you running Oracle E-Business Suite (EBS) / Applications and want to get an operating system level environment variable value from a database table, for example for use in PL/SQL? Or perhaps to default a concurrent program parameter? Didn't think environment variables were stored in the database?

Try out out this query that shows you $FND_TOP:

select value
from   fnd_env_context
where  variable_name = 'FND_TOP'
and    concurrent_process_id = 
      ( select max(concurrent_process_id) from fnd_env_context );

VALUE
--------------------------------------------------------------------------------
/d01/oracle/VIS/apps/apps_st/appl/fnd/12.0.0

Or did you want to find out the Product "TOP" directories e.g the full directory path values from fnd_appl_tops under APPL_TOP?

Lessons in Loose Coupling – Special Delivery

Photo credit: Kordite@Flickr

I'm generally nervous when I hear people that deal with software throw around the phrase "loosely coupled" with exhuberance. For me, loose coupling is one of the few phrases that resonates a feeling of ambivalence. An abstraction layer is a necessity, especially in proprietory software, to give you the coding hooks you need. Just be careful though to avoid Special Deliveries of Coal. Classic!

Catch ya!
