hi,
below is my listener.ora
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = /opts/u01/app/oracle/product/11.2.0/db_1)
(PROGRAM = extproc)
)
(SID_DESC =
(GLOBAL_DBNAME = TARGET)
(ORACLE_HOME =/opts/u01/app/oracle/product/11.2.0/db_1)
(SID_NAME = TARGET)
)
)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.1.0.13)(PORT = 1521))
)
)
ADR_BASE_LISTENER = /opts/u01/app/oracle
my question is:
1.) why is there a unknown status at:
Service "TARGET" has 2 instance(s).
Instance "TARGET", status UNKNOWN, has 1 handler(s) for this service...
Instance "TARGET", status READY, has 1 handler(s) for this service...
isn't it should be :
Service "TARGET" has 1 instance(s).
Instance "TARGET", status READY, has 1 handler(s) for this service...
------------------------------
