IIS-CONN-HIVE-30019I The connector could not determine the value for the fetch size.
Explanation
This message indicates that the connector tried to set and determine the effective fetch size,
but the driver returned an error.
User response
No action is required if the driver does not support setting the fetch size. If the driver
supports setting the fetch size, run the job with CC_MSG_LEVEL environment variable set to
level 2 to obtain debug level job log. The job log will contain the details about the error
that the driver returned when the connector tried to set and read the fetch size.
