The Db2 environment could not be initialized. Either enter a valid Db2 instance into the
Instance property or verify that the Db2.NSTANCE environment variable is set to a valid Db2 instance.
An error occurred when the connector requested Db2 to allocate an environment handle. Db2 cannot allocate an environment handle when the environment is not property configured.
If the Instance property in the connector is set, then verify that the value is valid. If
the Instance property is empty, verify that the Db2.NSTANCE environment variable is set to
a valid Db2 instance.
