Java JDBC - 如何使用服务名称而不是SID连接到Oracle [英] Java JDBC - How to connect to Oracle using Service Name instead of SID
问题描述
我有一个使用JDBC(通过JPA)的Java应用程序,它使用主机名,端口和Oracle SID连接到开发数据库,如下所示:
I have a Java application that uses JDBC (via JPA) that was connecting to a development database using hostname, port and Oracle SID, like this:
jdbc:oracle:thin:@ oracle.hostserver1.mydomain.ca:1521:XYZ
XYZ是Oracle SID。现在我需要连接到不使用SID的不同Oracle数据库,而是使用Oracle服务名称。
XYZ was the Oracle SID. Now I need to connect to a different Oracle database that does not use a SID, but uses an Oracle "Service Name" instead.
我试过这个,但它没有工作:
I tried this but it doesn't work:
jdbc:oracle:thin:@ oracle.hostserver2.mydomain.ca:1522:ABCD
ABCD是另一个数据库的服务名称。
ABCD is the Service Name of the other database.
我做错了什么?

精简式服务名称语法
Thin-style Service Name Syntax
仅支持精简式服务名称JDBC瘦驱动程序。语法为:
Thin-style service names are supported only by the JDBC Thin driver. The syntax is:
@ // host_name:port_number / service_name
@//host_name:port_number/service_name
例如:
jdbc:oracle:thin:scott / tiger @ // myhost:1521 / myservicename
jdbc:oracle:thin:scott/tiger@//myhost:1521/myservicename
所以我会尝试:
jdbc:oracle:thin:@ // oracle.hostserver2.mydomain.ca:1522/ABCD
jdbc:oracle:thin:@//oracle.hostserver2.mydomain.ca:1522/ABCD
另外,根据Robert Greathouse的回答,您还可以在JDBC URL中指定TNS名称,如下所示:
Also, per Robert Greathouse's answer, you can also specify the TNS name in the JDBC URL as below:
jdbc:oracle:thin:@(DESCRIPTION =(ADDRESS_LIST =(ADDRESS =(PROTOCOL=TCP)(HOST=blah.example.com)(PORT=1521)))(CONNECT_DATA=(SID=BLAHSID)(GLOBAL_NAME=BLAHSID.WORLD)(SERVER=DEDICATED)))
