1.平台ORACLE10G RAC,反复lsnrctl stop(start)但，结果还是此报错！
2.用CRS_STATS查看状态
rac1-> crs_stat -t
Name Type Target State Host
------------------------------------------------------------
ora.....CRM.cs application OFFLINE OFFLINE
ora....db1.srv application OFFLINE OFFLINE
ora.devdb.db application ONLINE ONLINE rac2

ora....C2.lsnr application ONLINE OFFLINE
ora.rac2.gsd application ONLINE ONLINE rac2
ora.rac2.ons application ONLINE ONLINE rac2
ora.rac2.vip application ONLINE ONLINE rac2
可以看到状态都为OFFLINE，虽然用lsnrctl status可以看到监听已经起来了；
3.查看LISTENER.ORA，注释(PROGRAM = extproc)
rac1-> more listener.ora
# listener.ora.rac1 Network Configuration File: /u01/oracle/product/10.2.0/db_1/network/admin/listener.ora.rac1
# Generated by Oracle configuration tools.
LISTENER_RAC1 =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
(ADDRESS = (PROTOCOL = TCP)(HOST = rac1-vip)(PORT = 1521)(IP = FIRST))
(ADDRESS = (PROTOCOL = TCP)(HOST = 172.16.96.171)(PORT = 1521)(IP = FIRST))
)
)
SID_LIST_LISTENER_RAC1 =
(SID_LIST =
(SID_DESC =
(SID_NAME = devdb1)
(ORACLE_HOME = /u01/oracle/product/10.2.0/db_1)
# (PROGRAM = extproc)
)
)
4.2节点上分别执行
srvctl stop listener -n rac1
srvctl stop listener -n rac2
srvctl start listerner -n rac1
srvctl start listener -n rac2
5.再次查看状态,可以看到已经起来了
rac2-> crs_stat -t
Name Type Target State Host

6.再次用PL/SQL DEVELOPER连接，OK！
