A program executing under the central version can be directed to access a specific database by using a DCUF SET DBNAME command. DCUF SET DBNAME establishes a default database for the current logical terminal and overrides the subschema named in the program's BIND RUN-UNIT statement. For example, to establish EMPTSTDB as the default database, either the user or the program can issue this CA IDMS command:
DCUF SET DBNAME EMPTSTDB
For more information on specifying a default database, see CA IDMS System Operations Guide.
'z/OS systems'. The specified database can be overridden by a specification in an IDMSOPTI module or SYSCTL file.
'Z/VSE systems'. The specified database can be overridden by a specification in an IDMSOPTI module.
