oracle共享服务器配置汇总(53天)

oracle共享服务器配置汇总对于共享服务器的配置进行了汇总，也发现一些隐藏的错误

方式一，多种监听（专用连接有专有连接的监听，共享服务有共享服务的监听）方式二，一种监听，专有和共享的都设定在一个监听上以下，ｌｉｓｔｅ１是专有服务器连接方式，　　　ｌｉｓｔｅ２是专门的共享服务器连接方式　　　ｌｉｓｔｅ３是专有服务和共享服务混合的方式

listener.ora　配置如下。 LISTE1 = (ADDRESS_LIST= (ADDRESS=(PROTOCOL=tcp)(HOST=oel1.oracle.com)(PORT=1521)) )

SID_LIST_LISTE1= (SID_LIST= (SID_DESC= (GLOBAL_DBNAME=PROD.oracle.com) (SID_NAME=PROD) (ORACLE_HOME=/u01/app/oracle/product/10.2.0/db_1) ) )

LISTE2 = (ADDRESS_LIST= (ADDRESS=(PROTOCOL=tcp)(HOST=oel1.oracle.com)(PORT=1529)) ) SID_LIST_LISTE2= (SID_LIST= (SID_DESC= (GLOBAL_DBNAME=PROD.oracle.com) (SID_NAME=PROD) (ORACLE_HOME=/u01/app/oracle/product/10.2.0/db_1) ) )

LISTE3 = (ADDRESS_LIST= (ADDRESS=(PROTOCOL=tcp)(HOST=oel1.oracle.com)(PORT=1520)) (ADDRESS=(PROTOCOL=tcp)(HOST=oel1.oracle.com)(PORT=1530)) )

SID_LIST_LISTE3= (SID_LIST= (SID_DESC= (GLOBAL_DBNAME=PROD.oracle.com) (SID_NAME=PROD) (ORACLE_HOME=/u01/app/oracle/product/10.2.0/db_1) ) )

tnsnames.ora　文件配置如下－－配置了多个端口的专用服务连接 PROD = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = tcp)(HOST = oel1.oracle.com)(PORT = 1520)) (ADDRESS = (PROTOCOL = tcp)(HOST = oel1.oracle.com)(PORT = 1521)) ) (CONNECT_DATA = (SERVICE_NAME = PROD.oracle.com) ) ) －－配置了共享服务连接 SPROD = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = tcp)(HOST = oel1.oracle.com)(PORT = 1529)) ) (CONNECT_DATA = (SERVICE_NAME = PROD.oracle.com) (SERVER=SHARED) ) ) －－配置共享服务连接，验证可以有多个共享服务器并存 XPROD = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = tcp)(HOST = oel1.oracle.com)(PORT = 1530)) ) (CONNECT_DATA = (SERVICE_NAME = PROD.oracle.com) (SERVER=SHARED) ) )

－－配置ｄｉｓｐａｔｃｈｅｒ SQL> show parameter dispatch

NAME TYPE VALUE ------------------------------------ ----------- ------------------------------ dispatchers string (protocol=tcp)(service=PROD.or acle.com)(dispatchers=2) max_dispatchers integer 2 －－根据需要来配置共享服务的参数。当然ｓｅｓｓｉｏｎ，ｐｒｏｃｅｓｓｅｓ也需要相应的设置，如果值太小，共享服务连接就会很慢。

SQL> show parameter shared

NAME TYPE VALUE ------------------------------------ ----------- ------------------------------ hi_shared_memory_address integer 0 max_shared_servers integer 2 shared_memory_address integer 0 shared_pool_reserved_size big integer 4404019 shared_pool_size big integer 0 shared_server_sessions integer 50 shared_servers integer 1

－－配置本地监听！！！如果配置的共享服务时非默认监听Listeners，默认端口１５２１，则需要在ｌｏｃａｌ　ｌｉｓｔｅｎｅｒ中注册。因为我建了两个监听ｌｉｓｔｅ２，ｌｉｓｔｅ３，所以把它们的端口信息都注册进去 alter system set local_listener='(address_list=(address=(protocol=tcp)(host=oel1.oracle.com)(port=1529))(address=(protocol=tcp)(host=oel1.oracle.com)(port=1530)))';

SQL> show parameter local_lis

NAME TYPE VALUE ------------------------------------ ----------- ------------------------------ local_listener string (address_list=(address=(protoc l=tcp)(host=oel1.oracle.com)( port=1529))(address=(protocol= tcp)(host=oel1.oracle.com)(por t=1530))) －启动监听 LSNRCTL> start liste1
