【Oracle】修改oracle监听端口

修改oracle 监听端口号，过程相对比较简单： 1 修改 listener.ora ,tnsnames.ora 文件中的端口号 2 重启监听 lsnrctl stop ，lsnrctl start 上面的过程是对于 监听名为默认的LISTENER 而言的，如果listener.oar文件中的监听名不是默认的，就重启时必须指定监听名。比如将端口号由1521改为1523 oracle@rac3:/opt/oracle/11.2.0/alifpre/network/admin vi listener.ora  # listener.ora Network Configuration File: /opt/oracle/11.2.0/alifpre/network/admin/listener.ora # Generated by Oracle configuration tools. yangdb =   (DESCRIPTION_LIST =     (DESCRIPTION =       (ADDRESS = (PROTOCOL = TCP)(HOST = rac3)(PORT = 1523))     ) ADR_BASE_LISTENER = /opt/oracle oracle@rac3:/opt/oracle/11.2.0/alifpre/network/admin vi tnsnames.ora  # tnsnames.ora Network Configuration File: /opt/oracle/11.2.0/alifpre/network/admin/tnsnames.ora # Generated by Oracle configuration tools. yangdb =   (DESCRIPTION =     (ADDRESS = (PROTOCOL = TCP)(HOST = 10.250.7.241 )(PORT = 1523))     (CONNECT_DATA =       (SERVER = DEDICATED)       (SERVICE_NAME = yangdb)     ) "tnsnames.ora" 77L, 1572C 已写入   重启监听： oracle@rac3:/opt/oracle/11.2.0/alifpre/network/admin lsnrctl stop LSNRCTL for Linux: Version 11.2.0.1.0 - Production on 11-NOV-2011 01:09:20 Copyright (c) 1991, 2009, Oracle.  All rights reserved.
