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

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。

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)))';

所以本地监听的配置是必须的。
