  Inside IBM DB2 Viper | InfoWorld | Review | 2006-08-14 | By Sean McCown
Ordinarily, the query optimizer uses statistics to estimate cardinality of the data stored in tables, and this is one of the major factors used to determine an execution plan for a given query.
DB2 9.1 is catching up, albeit with a slightly different method.
Because DB2 keeps the compression dictionaries in memory, my guess is that the lower memory of the server is causing the compression dictionaries to be paged to disk when the server is busy.

DB2 use the multiple indexes to satisfy multiple predicates in a SELECT statement that are joined by an AND or OR.
For a clustered index DB2 maintains rows in the same sequence as the columns in the index for as long as there is free space.
It is a DB2 facility for static SQL statements - it replaces these statements with calls to the DB2 language interface module.

  DB2 Standards - Application Programming
DB2 processes the request, returns the data (or error code) to the interface which then sends the data to the Report Writer component of FOCUS for completion of processing.
Avoid an arithmetic expression in a predicate: DB2 does not use an index on a cursor for a column it expects to be updated unless the updated column is qualified by an equal predicate and the preceding key columns are also qualified by equal predicates.
DB2 will automatically rebind the plans the next time they execute, however, for performance reasons it is better to manually rebind invalid plans.

Early versions of DB2 did not provide any means in SQL syntax to connect to a database at execution time; instead you were expected to code calls to the appropriate SQL API routines.
You use the DB2 Compiler directive to give the DB2 ECM information such as the fact that you are using SQL, and which database you are using.
If you use the NOACCESS option of the DB2 Compiler directive or intend to execute the application on a machine other than the one it was compiled on, bind the application to a particular database before execution.
