- Which are two ways for a database service to be recognized by a listener in Oracle Database 12c?
A) Static registration in the listener.ora file using the service_name parameter
B) Dynamic Registration by the smon process
C) Static registration in the listener.ora file using the global_dbname parameter
D) Dynamic Registration by the pmon process
E) Dynamic Registration by the lreg process
Answer：AE
(解析：如果是靜態註冊的監聽，使用 service_name 設置值爲 cuug.oracle.com，但是在啓動實例時發現 service name 不是cuug.oracle.com，而是實例名，說明它沒有被承認(recognized);而用 global_dbname 設置的值就能夠被承認。動態註冊的只有用 lreg 進程纔可以。來自3組：1015267481)
