Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - Production
今天打开监听程序时，报以下错误：
TNS-12560: TNS:protocol adapter error
TNS-00507: Connection closed
开始认为是Linux本身内部错误，检查hosts文件：
[[email protected] ~]$ cat /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost
::1 localhost6.localdomain6 localhost6
没有什么问题。
检查listener.ora:
LISTENER =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost.localdomain)(PORT = 1521))
)
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = jing)
(ORACLE_HOME = /u01/app/oracle/product/11.2.0/dbhome_1)
(SID_NAME = orcl3939)
)
(SID_DESC =
(GLOBAL_DBNAME = tai)
(ORACLE_HOME = /u01/app/oracle/product/11.2.0/dbhome_1)
(SID_NAME = orcl3939)
)
)
SID_LIST_WEN =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = /u01/app/oracle/product/11.2.0/dbhome_1)
(PROGRAM = extproc)
)
)
WEN =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost.localdomain)(PORT = 1522))
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
)
)
检查tnsnames.ora:
diy =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS=(PROTOCOL=TCP)(HOST = localhost.localdomain)(PORT = 1522))
)
)
SQL> show parameter local_listener;
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
local_listener string DIY
SQL> show parameter service_names;
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
service_names string a,b,c,d,diy
SQL> show parameter instance_name;
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
instance_name string orcl3939
以上检查没有异样。
然后重启os后，竟然可以启动监听程序：
[[email protected] ~]$ lsnrctl start listener

以上原因不清楚是OS还是oracle造成的。网上有朋友遇到同样错误解决的方法blog.chinaunix.net/uid-20048945-id-471098.html，尚不明白我重启后可以使用。
