Syntax Description

The values for this option are DBMS-specific. See the DBMS-specific reference section for details.

Details

Here is what 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
the degree to which update activity of other concurrently executing application processes can affect the current application.

This option is ignored in the interfaces to DB2 under UNIX and PC Hosts and ODBC if you do not set UPDATE_LOCK_TYPE=ROW. See the locking topic for your interface in the DBMS-specific reference section for details.
