The degree of isolation defines the degree to which:
  • rows that are read and updated by the current application are available to other concurrently executing applications.
  • update activity of other concurrently executing application processes can affect the current application.
DB2 under UNIX and PC Hosts, ODBC: This option is ignored if you do not set the READ_LOCK_TYPE= LIBNAME option to ROW.
See the locking topic for your interface in the DBMS-specific reference section for details.
