LANGUAGE_CURSOR is a Boolean-valued connection property in jConnect that allows you to determine whether cursors are created as protocol cursors or language cursors:
If LANGUAGE_CURSOR is set to "false," all cursors created during a session are protocol cursors, which provide better performance. jConnect creates and manipulates the cursors by sending cursor commands as tokens in the TDS protocol.
By default, LANGUAGE_CURSOR is set to "false."
If LANGUAGE_CURSOR is set to "true," all cursors created during a session are language cursors. jConnect creates and manipulates the cursors by sending SQL statements to the database for parsing and compilation.
There is no known advantage to setting LANGUAGE_CURSOR to "true," but the option is provided in case an application displays unexpected behavior when LANGUAGE_CURSOR is "false."
