(SET ANNOTATION ‘this is a virtual db created using DSL api’ | NULL)?

———————————————————————————————————————————————————————————————

ALTER VIRTUAL DATABASE ‘name’ (RENAME AS ‘newName’)?

(SET ANNOTATION ‘this is a virtual db created using DSL api’ | NULL)?

———————————————————————————————————————————————————————————————

SELECT * FROM model.ALL_DATASOURCES WHERE PARENT_PATH = '/services/databases' //to view all published virtual relational datasources

———————————————————————————————————————————————————————————————

//to get the resource properties

SELECT * FROM model.ALL_RESOURCE_PROPERTIES WHERE

        METADATA_ID =

            (SELECT DATASOURCE_ID FROM model.ALL_DATASOURCES

            WHERE DATASOURCE_NAME = 'name' AND                              //name of virtual db

            PARENT_PATH = '/services/databases');                           //parent path of the folder

———————————————————————————————————————————————————————————————

//to get database attribute definitions for Composite Database.

SELECT * FROM model.SYS_DATASOURCE_ATTRIBUTE_DEFS WHERE adapter_name = 'COMPOSITE_DATABASE'
