Changing the database configuration across multiple database partitions
When you have a database that is distributed across more than one database partition, the database configuration file should be the same on all database partitions.
Consistency is required since the SQL compiler compiles
distributed SQL statements based on information in the database partition
configuration file and creates an access plan to satisfy the needs
of the SQL statement. Maintaining different configuration files on
database partitions could lead to different access plans, depending
on which database partition the statement is prepared. Use db2_all to
maintain the configuration files across all database partitions.
