【強調一點】
由於oracle實例的動態註冊只能在默認端口1521上運行，端口修改後監聽一定要記得修改爲“靜態註冊”方式。
否則您永遠也等不到LISTENER動態監聽到您的oracle實例！
【修改步驟】
1.修改listener.ora文件，端口從1521修改成1526；同時將監聽改爲“靜態註冊”
listener.ora文件修改前：
ora10g@testdb /home/oracle$ cat $ORACLE_HOME/network/admin/listener.ora
# listener.ora Network Configuration File: /oracle/app/oracle/product/10.2.0/db_1/network/admin/listener.ora
# Generated by Oracle configuration tools.
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = /oracle/app/oracle/product/10.2.0/db_1)
(PROGRAM = extproc)
)
)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 144.194.192.183)(PORT = 1521)(IP = FIRST))
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
)
)
listener.ora文件修改後：
ora10g@testdb /home/oracle$ cat $ORACLE_HOME/network/admin/listener.ora
# listener.ora Network Configuration File: /oracle/app/oracle/product/10.2.0/db_1/network/admin/listener.ora
# Generated by Oracle configuration tools.
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = /oracle/app/oracle/product/10.2.0/db_1)
(PROGRAM = extproc)
)
(SID_DESC = ## 靜態註冊在這裏體現
(GLOBAL_DBNAME = ora10g)
(ORACLE_HOME = /oracle/app/oracle/product/10.2.0/db_1)
(SID_NAME = ora10g)
)
)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 144.194.192.183)(PORT = 1526)(IP = FIRST)) ## 端口修改在這裏體現
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
)
)
2.修改tnsnames.ora文件，將其中出現的1521端口號修改爲1526
ora10g@testdb /home/oracle$ cat $ORACLE_HOME/network/admin/tnsnames.ora
# tnsnames.ora Network Configuration File: /oracle/app/oracle/product/10.2.0/db_1/network/admin/tnsnames.ora
# Generated by Oracle configuration tools.
ORA10G =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 144.194.192.183)(PORT = 1526))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = ora10g)
)
)
EXTPROC_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
)
(CONNECT_DATA =
(SID = PLSExtProc)
(PRESENTATION = RO)
)
)
3.重新啓動LISTENER
LSNRCTL> stop
LSNRCTL> start

4.使用ora10g進行測試
ora10g@testdb /home/oracle$ sqlplus sec/sec@ora10g
SQL*Plus: Release 10.2.0.1.0 - Production on Tue Jul 21 16:21:32 2009

Connected to:
Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - 64bit Production
With the Partitioning, Oracle Label Security, OLAP and Data Mining Scoring Engine options
sec@ora10g>
一切OK，修改成功！
【買一贈一】修改監聽端口號後企業管理器（Enterprise Manager）對應的調整
1.修改emoms.properties屬性文件中端口信息
ora10g@testdb /home/oracle$ vi $ORACLE_HOME/${HOSTNAME}_${ORACLE_SID}/sysman/config/emoms.properties
這個文件中有兩行含有1521端口號的信息，將他們統統的修改爲1526
oracle.sysman.eml.mntr.emdRepPort=1521
oracle.sysman.eml.mntr.emdRepConnectDescriptor=(DESCRIPTION\=(ADDRESS_LIST\=(ADDRESS\=(PROTOCOL\=TCP)(HOST\=testdb)(PORT\=1521)))(CONNECT_DATA\=(SERVICE_NAME\=ora10g)))
這兩個行修改後的內容如下
oracle.sysman.eml.mntr.emdRepPort=1526
oracle.sysman.eml.mntr.emdRepConnectDescriptor=(DESCRIPTION\=(ADDRESS_LIST\=(ADDRESS\=(PROTOCOL\=TCP)(HOST\=testdb)(PORT\=1526)))(CONNECT_DATA\=(SERVICE_NAME\=ora10g)))
2.修改targets.xml配置文件中端口信息
ora10g@testdb /home/oracle$ vi $ORACLE_HOME/${HOSTNAME}_${ORACLE_SID}/sysman/emd/targets.xml
這個文件中的1521端口號的信息統統的修改爲1526
3.重啓EM
ora10g@testdb /home/oracle$ emctl stop dbconsole
TZ set to PRC

4.驗證EM登陸
在本地瀏覽器中輸入如下的URL
http://144.194.192.183:5500/em/
看到登陸界面了，OK，搞定ed。
