By default, cursor operations are not logged in the IQ message file. If you need to track cursor operations in order to determine the cause of a problem, turn on the LOG_CURSOR_OPERATIONS option to produce a message each time a cursor is opened or closed. Data changes made through an updatable cursor are also logged in the IQ message file. See Chapter 2, “Database Options” in the Sybase IQ Reference Manual for details on the LOG_CURSOR_OPERATIONS option.
