Function
Defines the page size, in bytes, for on-disk database pages for tables or
indexes used during table or index creation. Set this property prior to issuing
the CREATE TABLE or CREATE INDEX statement. This value will be used for the
lifetime of the newly created conglomerates.
Valid conglomerates
Tables and indexes, including the indexes created to enforce constraints.
Default
automatically tunes
for the database page size. If you have long columns, the default page size for
the table is set to 32768 bytes. Otherwise, the default is 4096 bytes.
Valid values
Page size can only be one the following values: 4096, 8192, 16384, or 32768
bytes. If you specify an invalid value,
uses the default
value.
Example
-- changing the default for the system
derby.storage.pageSize=8192
-- changing the default for the database
CALL SYSCS_UTIL.SYSCS_SET_DATABASE_PROPERTY(
'derby.storage.pageSize',
'8192')
