数据库迁移前没有问题。迁移前版本为ORACLE 12.1。
数据库从oracle 12.1迁移到12.2之后,就出问题了。
应用服务器tomcat 7 出现如下报错信息:

自己修改过sqlnet.ora
NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)
SQLNET.ALLOWED_LOGON_VERSION_SERVER=8
SQLNET.ALLOWED_LOGON_VERSION_CLIENT=8

修改sqlnet.ora之后报错信息变成:java.sql.SQLException: ORA-01017: invalid username/password; logon denied

确认过该连接用户名和密码都能够连接,用sqlplus测试的。

请教一下如何诊断?

更换tomcat 7的jdbc驱动后恢复。
之前jdbc驱动是oracle-jdbc6.jar
更换成oracle-jdbc7.jar
