INFORMIXCMCONUNITNAME environment variable

If the Connection Manager raises an event alarm, the INFORMIXCMCONUNITNAME environment variable is used to store the name of the Connection Manager connection unit that raised the alarm. The environment variable is set automatically by the Connection Manager.

The INFORMIXCMCONUNITNAME environment variable corresponds to the connection unit name parameter in the Connection Manager configuration file. The environment variable is used by the CMALARMPROGRAM program to determine the Connection Manager instance responsible for the event alarm. You can also use the environment variable in your own Connection Manager event alarm handler.

The environment variable is set automatically by the Connection Manager and should not be modified.
