oracle之 单实例监听修改端口
Oracle 单一主机多个实例多个监听器配置要点 1. 一台服务器主机, 有多个实例, 如: TSDB/ORCL; 又需要配置多个监听器 2. 需要指定不同的LISTENER端口 3.pmon只会动态注册port等于1521的监听器, 其它端口则pmon不能动态注册listener, 要想让pmon动态注册listener, 需要设置local_listener参数 [oracle@12c01 admin]$ cat listener.ora ANDYCDB = (DESCRIPTION_LIST = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = 12c01)(PORT = 1521)) (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521)) ) ) ANDYCDB_TEST = (DESCRIPTION_LIST = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = 12c01)(PORT = 1522)) ) ) [oracle@12c01 admin]$ cat tnsnames.ora # tnsnames.ora Network Configuration File: /home/oracle/app/oracle/product
