The location name maps
to the location in the SYSIBM.LOCATION catalog in the communication
database.
In
SAS/ACCESS Interface
to DB2 under
z/OS, the location is converted to the first level of
a three-level table name:
location.authid.table.
The DB2 Distributed Data Facility (DDF) makes the connection implicitly
to the remote DB2 subsystem when DB2 receives a three-level name in
an SQL statement.
If you omit this option,
SAS accesses the data from the local DB2 database unless you have
specified a value for the SERVER= option. This option is not validated
until you access a DB2 table.
