發現一臺機器中同時執行多個Oracle例項時。。。
發現一臺機器中同時執行多個Oracle例項時，最好保證 [OracleHome]/network/admin/listener.ora 檔案的 SID_LIST_LISTENER 段中 要對應每個例項都有一段宣告
其實這是個很簡單的問題，呵呵，只是偶以前一直沒留意過，今天剛剛發現。
例如
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
)
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = housename)(PORT = 1521))
)
)
)
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = d:/oracle/ora92)
(PROGRAM = extproc)
)
--就是在這裡，最好為每個例項有對應的一段
(SID_DESC =
(GLOBAL_DBNAME = Ora1)
(ORACLE_HOME = d:/oracle/ora92)
(SID_NAME = Ora1)
)
(SID_DESC =
(GLOBAL_DBNAME = Ora2)
(ORACLE_HOME = d:/oracle/ora92)
(SID_NAME = Ora2)
)
-----------
)
