Default Schema is the name of the DB2 collection where the driver or the provider looks for catalog information. This is an optional parameter that can be specified while configuring ODBC and OLE DB Data Sources for DB2 to restrict results sets for popular operations, such as enumerating a list of tables in a target collection (for example, ODBC Catalog SQLTables).
If this paramater is not specified (left blank), the driver or the provider uses the default values depending on the platform that DB2 is running on. For DB2 (on Mainframe), it defaults to SYSIBM, for DB2/400 it defaults to QSYS2, and for UDB the default value is SYSCAT.
Retrieving all the tables within these global defaults could be time consuming for the driver and the provider, therefore, it is recommended that you specify the name of the target collection whenever possible.
