Adding New Data Sources

To add a new data source entry in the ODBCDSN file, include the data source name

and its description. If the values of the parameters are not specified in the ODBCDSN

file, the OSS ODBC/MX Client Driver uses default values when creating a connection.

Modifying Data Sources

To modify a data source entry, complete the following steps:

1. Modify the ODBCDSN file.

2. Restart the application to reflect the modified changes.

Removing Data Sources

To remove a data source entry, complete the following steps:

1. Edit the ODBCDSN file to remove the data source and its values and save the file.

2. Restart the application to reflect the edited changes.

Tracing OSS ODBC/MX Client Driver

Configure Tracing on a Client Data Source

Tracing of ODBC is enabled or disabled through the ODBCDSN file. This is determined

at the time when all other parameters are fetched from the ODBCDSN file before

establishing connection between the MXOSRVR and the OSS ODBC/MX Client Driver.

If tracing is enabled, the global trace flag is set and all the traceable ODBC data is

logged into the trace file henceforth.

The tracing parameters of the ODBCDSN file are:

•

[ODBC] parameter signifies the tracing support for ODBC.

•

TraceStart parameter determines whether the tracing facility is enabled or

disabled.

•

TraceFlags parameter indicates the tracing level.

Note. It is mandatory to restart the application to view the modified changes in the

ODBCDSN file.

Note. It is mandatory to restart the application to view the edited changes in the

ODBCDSN file.

Note.

To turn tracing on or off, modify the ODBCDSN file accordingly and restart

the application.
