Managing Oracle BI Discoverer Connections 3-7
When Discoverer end users connect to Discoverer Plus or Discoverer Viewer, they can select the connection that you created.
Notes
■
For information about finding out the unique ID of a connection, see Section 12.4.3, How to find out the connection ID of a connection
.
■
If you specify a database by using the full tnsnames entry for the database SID, address, and port, you can connect to databases that do not have an entry in the
tnsnames.ora file on the Discoverer middle tier.
For example, you might enter the following string in the Database field:
DESCRIPTION=ADDRESS_LIST=ADDRESS = PROTOCOL=TCPHOST=machine_
a.company.comPORT=1521CONNECT_DATA=SERVICE_ NAME=database1
Ensure that you remove spaces from the TNS string.
■
By default, users must enter the TNS alias of the database when creating connections to Discoverer. You can, however, allow users to enter a connect string
rather than a TNS alias, by setting the environment variable DISCOVERER_ ALLOW_DB_CONNECT_STRING to YES.
