After Oracle 11.2.0.4 database is upgraded to 19C, the original interface program reports an error: invalid connection string format, a valid format is host:ip :port
The reason is: Java variables refer to classes12. Jar and Ojdbc14. Jar, which leads to conflicts
Solution: after removing classes12. Jar, it will be normal.
In addition, the program should use JDK1.8 and ojdbc8.jar or above synchronously, which is a big change.
Relevant information:
The driver package classes12.jar is used for JDK 1.2 and JDK 1.3, while ojdbc14.jar is used for JDK 1.4
