Starting with version 11.70xC4, you can view the values that the database server sets in the INFORMIXCMNAME and INFORMIXCMCONUNITNAME environment variables when writing an alarm handler for the Connection Manager. If the Connection Manager raises an event alarm, the server automatically creates and stores:
- The Connection Manager instance name in the INFORMIXCMNAME environment variable
- The Connection Manager connection unit name in the INFORMIXCMCONUNITNAME environment variable.
