完全正确

https://stackoverflow.com/questions/1646630/what-is-the-correct-jdbc-url-to-connect-to-a-rac-database

jdbc:oracle:thin:@(DESCRIPTION=(ADDRESS_LIST=(LOAD_BALANCE=OFF)(FAILOVER=ON)
(ADDRESS=(PROTOCOL=TCP)(HOST=tst-db1.myco.com)(PORT=1604))
(ADDRESS=(PROTOCOL=TCP)(HOST=tst-db2.myco.com)(PORT=1604)))
(CONNECT_DATA=(SERVICE_NAME=mydb1.myco.com)(SERVER=DEDICATED)))

 

官方文档, 一如既往地冗长, 可靠

PoolDataSource pds = PoolDataSourceFactory.getPoolDataSource();

这个第三方总结很简单, 看样子是第三方驱动厂商

Resolution
 When creating the bootstrap use the following formats for the JDBC connection string.

Case 1: When using tibcosoftwareinc.jdbc.oracle.OracleDriver driver (Oracle (DataDirect)), JDBC URL field should contain:
jdbc:tibcosoftwareinc:oracle://<myhost1>:<myport1>SID=<myservice1>AlternateServers=(<myhost2>:<myport2>SID=<myservice2>)
Example URL:
jdbc:tibcosoftwareinc:oracle://host1:1521;ServiceName=orcl;AlternateServers=(host2:1521)
Case 2: When using oracle.jdbc.driver.OracleDriver (the native driver form Oracle), the JDBC URL field should contain:
jdbc:oracle:thin:@(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=<myhost1>)(PORT=<myport1>))(SERVICE_NAME=<myservice1>))(ADDRESS=(PROTOCOL=TCP)(HOST=<myhost2>)(PORT=<myport2>))(LOAD_BALANCE=yes)(CONNECT_DATA=(SERVICE_NAME=<myservice2>)(FAILOVER_MODE=(TYPE=SELECT)(METHOD=BASIC)(RETRIES=180))))
Example URL:
jdbc:oracle:thin:@(DESCRIPTION=(LOAD_BALANCE=on)(ADDRESS=(PROTOCOL=TCP)(HOST=host1) (PORT=1521))(ADDRESS=(PROTOCOL=TCP)(HOST=host2) (PORT=1521))(CONNECT_DATA=(SERVICE_NAME=orcl)))
See more information in Oracle‘s documentation.
