1、创建了一个 数据库实例之后,需要配置 listener.ora,不然那个实例默认是不监听的
1.1、我修改了 这个文件,记录下来:
(1)修改前的:(原来 安装好Oracle后就存在的,没有动过的)
# listener.ora Network Configuration File: /opt/oracle/102/network/admin/listener.ora # Generated by Oracle configuration tools. SID_LIST_LISTENER = (SID_LIST = (SID_DESC = (SID_NAME = PLSExtProc) (ORACLE_HOME = /opt/oracle/102) (PROGRAM = extproc) ) ) LISTENER = (DESCRIPTION_LIST = (DESCRIPTION = (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1)) (ADDRESS = (PROTOCOL = TCP)(HOST = CentOS64x64)(PORT = 1521)) ) )
(2)修改后的:
# listener.ora Network Configuration File: /opt/oracle/102/network/admin/listener.ora # Generated by Oracle configuration tools. SID_LIST_LISTENER = (SID_LIST = (SID_DESC = (SID_NAME = PLSExtProc) (ORACLE_HOME = /opt/oracle/102) (PROGRAM = extproc) ) (SID_DESC = (SID_NAME = zzorcl) (ORACLE_HOME = /opt/oracle/102) (GLOBAL_DBNAME = zzorcl) ) ) LISTENER = (DESCRIPTION_LIST = (DESCRIPTION = (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1)) (ADDRESS = (PROTOCOL = TCP)(HOST = CentOS64x64)(PORT = 1521)) ) )
ZC:暂时还不太明白里面的含义,只是仿照网页上搜索到的写了一下,暂时只要做到能用就行...
2、新建的实例 默认是不运行的状态(idle),需要startup操作后 才能 做 "create user"等的操作
