The VORTEX_API_LOGOPTS environment variable specifies options for the file determined by VORTEX_API_LOGFILE.


One or more of the following, separated by a plus sign (+):

Vortex API logging is helpful in debugging queries. By recording Vortex API calls made by the xfODBC driver and SQL Connection, you can see the exact SQL statement issued to the database, debug SQL statement errors, and verify optimization.

Use the VORTEX_API_LOGFILE environment variable to specify the name and location of the log file that is generated. If you set VORTEX_API_LOGFILE without setting VORTEX_API_LOGOPTS, the log file includes a list of all operations along with a total count for each operation.

Once you have successfully logged the error, turn logging off by unsetting the VORTEX_API_LOGFILE and VORTEX_API_LOGOPTS environment variables (and reboot if necessary). Logging slows performance, and the log files can quickly fill your disk.

Setting location

The environment. For services such as web servers that use the xfODBC driver, you can use the Env. variables field in the xfODBC Setup window to set this environment variable on the client.
