CURRENTDATA for remote access

For requests to remote systems, the CURRENTDATA option applies to ambiguous cursors that use the following ISOLATION options: RR, RS, or CS.

For access to a remote table or index, CURRENTDATA(YES) turns off block fetching for ambiguous cursors. The data returned with the cursor is current with the contents of the remote table or index for ambiguous cursors. Turning on block fetch offers best performance, but it means that the cursor is not current with the base table at the remote site.
