oracle 监听静态注册举例解析
网上有很多关于oracle 监听静态注册的文章，但大多都是简单说说，并没有详细的例子，这里，将结合linux as3 下的oracle 10gR2.0.1 举一个具体的例子
1、在 $ORACLE_HOME/network/admin/listener.ora 文件中加入一个静态注册的节点
[oracle@guohui6 oracle]$ cd
$ORACLE_HOME
/
network
/
admin
[oracle@guohui6 admin]$ vi listener
.
ora
#
listener.ora Network Configuration File: /mydatafile2/app/oracle/oracle/product/10.2.0/db_1/network/admin/listener.ora
#
Generated by Oracle configuration tools.
SID_LIST_LISTENER
=
(SID_LIST
=
(SID_DESC
=
(SID_NAME
=
PLSExtProc)
(ORACLE_HOME
=
/
mydatafile2
/
app
/
oracle
/
oracle
/
product
/
10.2
.
0
/
db_1)
(PROGRAM
=
extproc)
)
(SID_DESC
=
(SID_NAME
=
ORCL)
(ORACLE_HOME
=
/
mydatafile2
/
app
/
oracle
/
oracle
/
product
/
10.2
.
0
/
db_1)
(GLOBAL_DBNAME
=
HJD
.
COM
.
CN)
)
)
LISTENER
=
(DESCRIPTION_LIST
=
(DESCRIPTION
=
(ADDRESS
=
(PROTOCOL
=
IPC)(
KEY
=
EXTPROC1))
(ADDRESS
=
(PROTOCOL
=
TCP)(HOST
=
guohui6)(PORT
=
1521
))
)
)
注意这里的global_dbname=HJD.COM.CN
SID_NAME=ORCL
这个SID_NAME 应与你对外提供服务的 $ORACLE_SID 一致
[oracle@guohui6 admin]$
echo
$ORACLE_SID
ORCL
2、配置对应的tnsnames.ora 中的节点
[oracle@guohui6 admin]$ vi tnsnames
.
ora
#
tnsnames.ora Network Configuration File: /mydatafile2/app/oracle/oracle/product/10.2.0/db_1/network/admin/tnsnames.ora
#
Generated by Oracle configuration tools.
ORCL
=
(DESCRIPTION
=
(ADDRESS
=
(PROTOCOL
=
TCP)(HOST
=
guohui6)(PORT
=
1521
))
(CONNECT_DATA
=
(SERVER
=
DEDICATED)
(SERVICE_NAME
=
ORCL)
)
)
GUOHUIORCL
=
(DESCRIPTION
=
(ADDRESS
=
(PROTOCOL
=
TCP)(HOST
=
guohui6)(PORT
=
1521
))
(CONNECT_DATA
=
(SERVER
=
DEDICATED)
(SERVICE_NAME
=
HJD
.
COM
.
CN)
)
)
tnsname GUOHUIORCL 中的 SERVICE_NAME=HJD.COM.CN
这里的服务名为 HJD.COM.CN 而不是通常的 ORCL，因为在 listener.ora 中已经注册了 HJD.COM.CN,lsnrctl 启动时会监听 HJD.COM.CN ，并对应到 SID_NAME=ORCL 上。
3、启动监听和服务
[oracle@guohui6 oracle]$ cat dbstart
lsnrctl start
sqlplus
/
nolog
<<
EOF
connect
/
as
sysdba
startup
EOF
[oracle@guohui6 oracle]$
./
dbstart

可以看到

4、验证该服务可以到达

Used TNSNAMES adapter to resolve the alias
Attempting to contact (DESCRIPTION

=
guohui6)(PORT

)) (CONNECT_DATA

OK (

tnsping guohuiorcl 就是刚才tnsnames.ora 中配置的 tnsname.可以看到，该地址可以通达。
5、利用静态注册的服务登入oracle
[oracle@guohui6 oracle]$ sqlplus tina
