When a database is enabled, a DTD reference table, DTD_REF, and an XML_USAGE table are created. The DTD_REF table contains information about all of the DTDs. The XML_USAGE table stores common information for each XML-enabled column.
The XML Extender uses the parameter UDB_SIZE to specify the size
of certain character parameters. The value of UDB_SIZE is
determined by the version of DB2 UDB that is running. The following
list shows the field size values for the different DB2 UDB versions.
DB2 UDB version | Size |
---|---|
6.1 | 32 |
7.1 | 64 |
