Environment variables reference

The table lists the environment variables for controlling how CICS® Transaction Gateway functions.

On Windows, environment variables and the configuration file control how the CICS Transaction Gateway functions. When an environment variable is intended for use with the Gateway daemon or Client daemon the variable must be defined as a system environment variable and the system must be restarted when the variable is first set or changed.

Table 1. Environment variables
Environment variable Description
CICSCLI See Specifying the configuration file
CLASSPATH

On UNIX and Linux set the CLASSPATH for the resource adapter Java™ classes. You must set the Java CLASSPATH environment variable so that the resource adapter Java classes can be used when an ECI request is sent to the CICS server.

On Windows, the CLASSPATH variable is updated by the installation process defining product jar files used by the CICS Transaction Gateway.

CTGDCONF (UNIX and Linux) See Running the Gateway daemon as a background process.
CTG_DATA_PATH (Windows)

Created by the installation process with the value of <product_data_path>. See File path terminology for more information.

CTG_JAVA See Specifying the JVM.
CTG_JNI_TRACE

Specify the name of the JNI trace file. See JNI tracing

CTG_JNI_TRACE_ON

Switch JNI tracing on. SeeJNI tracing

PATH (Windows)

Updated by the installation process to append <install_path>\bin.
