Environment Variables

Environment Variables

Before you use PowerExchange for Teradata Parallel Transporter API in the native or Hadoop environment, you must configure Java and Teradata environment variables.
In the native environment, set the environment variables on the node that runs the Data Integration Service. In the Hadoop environment, set the environment variables in the
hadoopEnv.properties
file. For more information, see the
Informatica Big Data Management User Guide
.
The following table describes the environment variables that you must configure on Windows and UNIX:
Environment Variable
Value
JAVA_HOME
<Informatica installation directory>/java
JRE_HOME
${JAVA_HOME}/jre
<Shared Library Variable>
Set the shared library variable to include
$TWB_ROOT/lib64
and
$TD_ICU_DATA/lib64
for 64-bit files.
Applicable when you run mappings in the native environment or on the Hive engine without using TDCH.
Set the shared library environment variable based on the operating system. The following table describes the shared library variables for each operating system:
Operating System
Value
Windows
PATH
Applicable when you run mappings in the native environment.
Linux
LD_LIBRARY_PATH
The following table describes the environment variables that you must configure on UNIX when you run mappings in the native environment or on the Hive engine without using TDCH:
Environment Variable
Value
COPERR
Set to the location of the
errmsg.cat
file.
For example:
