Setting Environment Variables on the PowerCenter Integration Service Machine

Setting Environment Variables on the PowerCenter Integration Service Machine

Set system environment variables before starting the PowerCenter Integration Service process.
The following table describes the system environment variables that you can set:
Environment Variable
Description
MQCHLTAB
Name of the file that contains the client channel definition table.
MQCHLLIB
Directory path to the file that contains the client channel definition table.
MQSERVER
Location of the WebSphere MQ server and the communication method you want to use. When you specify MQSERVER, the PowerCenter Integration Service can read and write WebSphere MQ messages up to 4 MB.
MQSSLKEYR
Location of the key repository that contains the digital certificate for secure sockets layer (SSL) configuration. See the IBM documentation for other SSL environment variables you might want to configure.
Use the following guidelines:
  • Set MQCHLTAB and MQCHLLIB for the PowerCenter Integration Service to be able to connect to multiple queue managers in a session.
  • To configure WebSphere MQ for SSL, set MQSSLKEYR, MQCHLTAB, and MQCHLLIB. Do not set MQSERVER.
  • To connect to one queue manger in a session without secure connections, set MQSERVER. When you set MQSERVER, WebSphere MQ ignores MQCHLTAB, MQCHLLIB, and MQSSLKEYR.
WebSphere MQ also provides other system environment variables. For more information, see the IBM WebSphere MQ documentation.
To set system environment variables:
  1. Stop the PowerCenter Integration Service process.
  2. Set the following values for the environment variables on the machine running the PowerCenter Integration Service process:
    Environment Variable
    Value
    MQCHLTAB 
    MQCHLTAB = AMQCLCHL.TAB
    MQCHLLIB 
    MQCHLLIB = <WebSphereMQ installation directory>/Qmgrs/<queue manager name>/@ipcc
    MQSSLKEYR 
    MQSSLKEYR = <WebSphereMQ installation directory>/Qmgrs/<queue manager name>/ssl/
<key repository>
    MQSERVER 
    MQSERVER = <server-connection channel name>/TCP/<host name>(<port nunber>)
    For example: 
    MQ_cseversonpc/TCP/cseversonpc(1414)
  3. Start the PowerCenter Integration Service process.
