The considerations that should be taken into account in determining the page length are discussed as follows.
To specify a page length, use the create rdarea statement of the database initialization utility (pdinit) or database structure modification utility (pdmod).
An error results when a row is added to a table and as a result the actual row length exceeds the page length (except in the case of columns whose data type is VARCHAR, NVARCHAR, or MVARCHAR). The actual row length is obtained using the formula for required disk space that is provided in Chapter 16. Determining RDAREA Size. If the obtained row length is greater than the page length of the user RDAREA to be used, the user RDAREA must be reinitialized and then the page size must be redefined. The database structure modification utility (pdmod) is used to reinitialize RDAREAs. For details about how to reinitialize RDAREAs, see the HiRDB Version 9 System Operation Guide.
