SQL Optimizer for DB2 LUW 4.3.1 - Release Notes

Connect to the Database

Prior to installing SQL Optimizer, a client/server system needs to be set up. Set up the host strings in DB2 Client Configuration Assistant to connect to the databases.

SQL Optimizer directly uses the DB2 Client Configuration Assistant to connect to the DB2 LUW database.

Loading information from the Data Dictionary

Information about the tables and indexes from the data dictionary needs to be loaded into the memory of the computer for every connection to a database. The Load data dictionary after database connection option determines whether information is loaded when the connection is made or whether the specific information needed from the database is loaded when a SQL statement is parsed for functions such as scanning, optimization, and index generation.
