Oracle配置共享服务器:
1.配置第二个监听
netca/手工
手工:listener.ora
LSNR_2 =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = Demon)(PORT = 1526))
)
)
2.启动LSR_2监听 lsnrctl start lsnr_2
3.配置tnsnames.ora
添加:
LSNR_2 =(ADDRESS = (PROTOCOL = TCP)(HOST = Demon)(PORT = 1526))
ORCL_1 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = Demon)(PORT = 1526))
(CONNECT_DATA =
(SERVER = SHARED)
(SERVICE_NAME = ORCL)
)
)
4.注册LSNR_2监听
show parameter service_names
show parameter local_listener
alter system set local_listener='LSNR_2';
alter system register;
注:到此为止,与创建第二监听的差别不是很大,只是改变了一个SERVER = SHARED参数;
此外还可修改数据库服务名,一个数据库可有多个服务名:
show parameter service_names
alter system set service_name=" ……";
alter system set service_names=ORCL,EG;
5.配置共享服务器参数
show parameter shared; 共享进程
show parameter dispatch; 调度参数
6.生成pfile,关库
create pfile from spfile;
shutdown immediate
7.修改参数文件
$ORACLE_HOME/dbs/
ls -ctl
vi initORCL.ora
在pfile参数文件中添加参数:
shared_servers=10
max_shared_servers=30
shared_server_sessiOns=200
dispatchers="(PROTOCOL=TCP) (DISPATCHERS=3)" /网络协议和调度程序参数
max_dispatchers=10
8.生成spfle ,,起库
create spfile from pfile;
startup
9.查看相关参数
show parameter shared; 共享进程
show parameter dispatch; 调度参数
10.测试
sqlplus hr/hr@ORCL_1
查看视图:
select server from v$session; /给予权限
