Environment Variables

This section describes the environment variables you can set for Cognos
Transformer on UNIX and Linux.
Before you start defining the environment variables, read the section "Controlling
Processing with Preference Settings or Environment Variables" on page 194.
Consider the following:
v Each environment variable must be defined before it is used in a command, and
v The environment variable must be alphanumeric (ASCII-text format), and may
v Special environment variable characters, such as $, {, or }, may appear in a file
v Variable substitution is not performed on the values of environment variables.
Shared Library Variables
To run Cognos Transformer on UNIX or Linux, the loader requires that the library
path variable specify the location of the shared libraries. The library path variable
for each supported operating system is as follows.
Database Variables
If your data sources make use of one or more relational databases, you must install
them before using Cognos Transformer. For more information, see the Cognos
Transformer information in the Installation and Configuration Guide.

Addressing Common UNIX and Linux Processing Problems

This section describes some tools and techniques for addressing common
processing problems in the UNIX or Linux environment.

Checking UNIX and Linux Job Status

When you use Cognos Transformer to create cubes, there are several options for
checking the cube processing status.
These options are as follows:
200
IBM Cognos Transformer Version 10.1.1: User Guide
available to Cognos Transformer during the PowerCube build. Cognos
Transformer can avoid memory exhaustion if WorkFileMaxSize is too high;
however, if there is not enough physical memory, cube build performance may
not be optimal.
must be preceded by a dollar character ($). Optionally, braces ({}) may be used
to enclose the environment variable name.
contain an underscore (_).
name or directory string if they are preceded by the escape character (\). This
backslash is automatically removed before the string is used. For example, a pair
of backslash characters (\\) is replaced by one backslash.
