In order to run the tests you'll need a working connection to a db2 server running with permissions to create and delete tables.
The connection information is taken from the following environment
variables which you can set to control this behavior:
schema: ENV{DBD_DB2_SCHEMA}
dbname: ENV{DBD_DB2_DBNAME}
user: ENV{DBD_DB2_USER}
password: ENV{DBD_DB2_PASSWD}
table: ENV{DBD_DB2_TABLE}
If any variable is not set, you are prompted for a value.
