One of the columns must meet three requirements:

Question 7

In the spfile of a single instance database, LOCAL_LISTENER is set to LISTENER_1.

The TNSNAMES.ORA file in $ORACLE_HOME/network/admin in the database home contains:

Which statement is true?

1. Dynamic service registration cannot be used for this database instance
2. The LREG process registers services dynamically with the LISTENER_1 listener
3. LISTENER_1 must also be defined in the LISTENER.ORA file to enable dynamic service registration
4. There are two listeners named LISTENER and LISTENER_1 running simultaneously using port 1521 on the same host as the database instances
5. The definition for LISTENER_1 requires a CONNECT_DATA section to enable dynamic service registration

Question 8

Question 10

Which three functions are performed by dispatchers in a shared server configuration? (Choose three.)

1. writing inbound request to the common request queue from all shared server connections
2. checking for outbound shared server responses on the common outbound response queue
3. receiving inbound requests from processes using shared server connections
4. sending each connection input request to the appropriate shared server input queue
5. broadcasting shared server session responses back to requesters on all connections
6. sending shared server session responses back to requesters on the appropriate connection ✅Correct Answer: A, C, F
1. writing inbound request to the common request queue from all shared server connections
3. receiving inbound requests from processes using shared server connections
6. sending shared server session responses back to requesters on the appropriate connection Dispatchers receive inbound requests from processes using shared server connections (C) and write those requests into the single common request queue that all shared server processes read (A). When the work is done, each dispatcher takes the result from its own response queue and returns it to the requester on the correct connection (F).
