ORA-28040：与oracle12c一起使用groovy.sql包时，没有匹配的身份验证协议异常

Question

I am trying to connect to oracle12c database using groovy.sql.Sql

Sql sql = Sql.newInstance('jdbc:oracle:thin:@'+hostName:port/serviceName, dbUser, dbPassword, 'oracle.jdbc.driver.OracleDriver')

and it returns

java.sql.SQLException: ORA-28040: No matching authentication protocol

I guess, this is because of the dialect mismatch.

It works fine with oracle11g , but not with 12c . If it is a problem with dialect , how can we externally specify dialect to groovy.sql.Sql . If not, what could be the problem/solution?

I'm using ojdbc14 driver.

Answer 1

The ojdbc14 is a relatively old driver and that could be the problem. I would recommend trying ojdbc6 and see if that fixes your problem.

Note that this appeared to fix a similar problem based on information in the comments in this SO question ORA-28040: No matching authentication protocol exception .

Answer 2

Are you referring to the dialect that is normally configured in DataSource.groovy ? If so, this is irrelevant when creating an Sql instance, because the dialect is only used by Hibernate/GORM.
