This article shows how to configure a Runtime environment for using Oracle Sql Loader.

This is useful when the Runtime server has no Oracle software pre-installed.

 

Download and install Oracle Instant Client

Download "Oracle Instant Client" from the Oracle downloads website.

Make sure to download the "Basic Instant Client" or the "Instant Client Light".

And of course also download the "Tools Package" which contains the Sql Loader utility.

Unzip all this material to a single directory, which will look like this:

D:\apps\oracle\instantclient_12_2>dir
 Volume in drive D is Data
 Volume Serial Number is 2891-91F0

 Directory of D:\apps\oracle\instantclient_12_2

Create the tnsnames.ora file

Create a directory and a text file named "tnsnames.ora". It will contain all your DB connection data strings.

In my example, "D:\apps\oracle\network\admin\tnsnames.ora" :

baseqa=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=qaoora11g2-01)(PORT=1521))(CONNECT_DATA=(SID=ORA112)))

 

Configure the Environment

Add the "Oracle Instant Client" installation directory to the system's Path variable (1).

And also add the new environment variable TNS_ADMIN to declare the location of "tnsnames.ora" (2).

Design your Metadata and Mappings

This is all you need to do in terms of Environment.

Now you can Create / Reverse your Oracle metadata.

Make sure the "Physical Name" of the oracle server reflects the database name in your tnsnames.ora file. In my example : "baseqa".

And develop your mapping, selecting the templates which use Sql Loader.
