```
[Db2]
Description = Db2 Driver
Driver = <instance_path>/lib/libdb2o.so
fileusage=1
dontdlclose=1
```
if you installed the full IBM®, the <instance_path> is your Db2 instance path, such as IBM Data Server Client, IBM Data Server Runtime Client, or Db2 database server product. If you installed the IBM Data Server Driver for ODBC and CLI, the <instance_path> is your installation path. You can determine the location of the odbcinst.ini configuration file by issuing the following command:
```
odbcinst –j
```
