我使用如下可以连接，但是把"server=dedicated"改为"server=shared"怎么就连不上了？
MISDB =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.1.10.251)(PORT = 1521))
(CONNECT_DATA = (SERVICE_NAME = misdb1.db.chnsys)(SERVER = shared))
)

我的oracle是MTS模式呀:
----------------------------
LSNRCTL> service
Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=IPC)(KEY=EXTPROC)))
Services Summary...
PLSExtProc has 1 service handler(s)
DEDICATED SERVER established:0 refused:0

The command completed successfully

报这个错误：
-----------------------------------------------------------------------
SQL> conn fb@misdb
Enter password:
ERROR:
ORA-12545: Connect failed because target host or object does not exist
-------------------------------------------------------------------------
有哪为大哥知道这是为什么呀！

但是我在安装oracle的那台机器上却可以使用
MISDB =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.1.10.251)(PORT = 1521))
(CONNECT_DATA = (SERVICE_NAME = misdb1.db.chnsys)(SERVER = shared))
)
