设置了shared server连接，dispatcher进程和shared server进程都没有问题
listener.ora文件配置如下：
LSNR2=
(DESCRIPTION=
(ADDRESS_LIST=
(ADDRESS=(PROTOCOL=tcp)(HOST=edbjr2p1.example.com)(PORT=1526))
))
SID_LIST_LSNR2=
(SID_LIST=
(SID_DESC=
(GLOBAL_DBNAME=PROD1)
(ORACLE_HOME=/u01/app/oracle/product/11.2.0/dbhome_1)
(SID_NAME=PROD1))
)
tnsnames.ora文件配置如下：
PROD1_S =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = edbjr2p1.example.com)(PORT = 1526))
(CONNECT_DATA =
(SERVER = SHARED)
(SID = PROD1)
)
)
但是连接出现错误：
[oracle@edbjr2p1 admin]$ sqlplus system/oracle@PROD1_S

ERROR:
ORA-12519: TNS:no appropriate service handler found
tnsnames.ora文件中shared更改为dedicated连接正常。
此时需要把local_listener.ora初始化参数添加LSNR2监听器,问题解决.
alter system set local_listener='LSNR2','LISTENER';
此参数可以让pmon可以注册实例到监听器
LOCAL_LISTENER specifies a network name that resolves to an address or address list of Oracle Net local listeners (that is, listeners that are running on the same machine as this instance). The address or address list is specified in the TNSNAMES.ORA file or other address repository as configured for your system.
