SYMPTOMS

Issuing a CURSORSETPROP() function without first issuing a SET MULTILOCKS ON command results in error number 1589. The error message is:

Table or Row Buffering Requires that SET MULTILOCKS is set to ON

CAUSE

You must enable multilocks prior to beginning to buffer through the CURSORSETPROP() function or through the interface.

RESOLUTION

Issue a SET MULTILOCKS ON command. You can handle this error in a program by using this error routine:

   ON ERROR DO errhandler

     PROCEDURE errhandler

       =aerror(aLastError)
       DO CASE
          CASE aLastError(1) = 1589
             SET MULTILOCKS ON
             RETRY
       ENDCASE

STATUS

This behavior is by design.

MORE INFORMATION

An on error routine should handle a variety of errors that may occur during processing. Include an OTHERWISE section within the DO CASE construct to handle errors that are not specifically included in the on error routine.
