上回把公司的BI库从11.2.0.1升级到11.2.0.4,最后监听出现了问题,挂在了1522端口上。
这两天一顿操作,把监听又换回到1521上,但是监听却出了问题,连不上数据库。登上去看了一下,lsnrctl status提示The listener supports no services,也就是说监听没有识别库,先后采用了两种方法,如下:
一、
SQL> show parameter service_names –查看服务名称
NAME TYPE VALUE
service_names string orcl
SQL>alter system register
system altered
SQL>exit
强制注册一遍,然后重新启动监听,发现还是不行。
二、在listener.ora中添加如下代码:
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = orcl)
(SID_NAME = orcl)
)
)
使之成为这样:
[oracle@oracle11g admin]$ cat listener.ora
# listener.ora Network Configuration File: /u01/app/oracle/product/11.2.0/db_1/network/admin/listener.ora
# Generated by Oracle configuration tools.
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = oracle11g)(PORT = 1521))
)
)
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = orcl)
(SID_NAME = orcl)
)
)
ADR_BASE_LISTENER = /u01/app/oracle
再重新启动监听,
lsnrctl stop
lsnrctl start
这下监听就正常了,也可以连上了。
