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)))';

所以本地监听的配置是必须的。
