OpenEdge Data Management: DataServer for Microsoft SQL Server

Initial Programming Considerations
2–42
The NO–WAIT option
The NO–WAIT option works for DataServer applications in the same way that it works for
OpenEdge applications: the DataServer uses a time-out mechanism. If MS SQL Server does not
return a record, the DataServer considers the record to be locked. It then cancels the request to
the MS SQL Server and sets the “locked” and “not available” conditions.
During a period of heavy demand, you might encounter situations where the “not available”
condition is set although the record is not currently locked by a user. In this case, you might want
to increase the time-out interval by using the -Dsrv RESP_TIMEOUT parameter.
