Current Explain Mode in DB2 Universal Database Version 6


UNIX OS/2 WIN

Change 

The type of the "CURRENT EXPLAIN MODE" special register has changed from CHAR(8) to VARCHAR(254).

Symptom  If the application assumes that the type is still CHAR(8), then the value may be truncated from 254 to 8 bytes.

Resolution 

Redefine the type of all host variables which read the special register from CHAR(8) to VARCHAR(254).

This change is required to accommodate two new values for the "CURRENT EXPLAIN MODE" special register. These new values are "EVALUATE INDEXES" and "RECOMMEND INDEXES".

Symptom

Resolution 

Ignore the warning message. See Data Movement Utilities Guide and Reference for additional information.
