Oracle三种连接方式
一、 CONNECT_DATA 设置为 oracle 的全局数据库名
TOS =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = soho-ivgcrcy9al)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = tos.lee.com)
)
)
假定数据库 init.ora 的参数设置为
db_name = tos
db_domain = lee.com
也可以直接指定 service_names = tos.lee.com
注意 ,service_names 是个动态参数， pmon 进程在动态的注册到 listener 时有延迟（大概几分钟）
二、设置 SERVICE_NAME 为 listener.ora 里的 GLOBAL_DBNAME 值
tnsnames.ora
TOS =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = soho-ivgcrcy9al)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = tos)
)
)
listener.ora
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(
GLOBAL_DBNAME = tos)
(ORACLE_HOME = D:oracleora92)
(SID_NAME = oracledb)
)
)
三、设置 sid 为 listener.ora 里的 sid_name 值
tnsnames.ora
TOS =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = soho-ivgcrcy9al)(PORT = 1521))
)
(CONNECT_DATA =
(sid = oracledb)
)
)
listener.ora
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(ORACLE_HOME = D:oracleora92)
(SID_NAME = oracledb)
)
)
其中后两种设置方式， listener.ora 中的 sid_name 必须和 instance_name 一致 .
