Question

在orcale里执行sql语句，提示ORA-03114：未连接到oracle，求解。

Answer 1

ORA-03114 not connected to ORACLE

Cause: A call to Oracle was attempted when no connection was established.
Usually this happens because a user-written program has not logged on. It may
happen if communication trouble causes a disconnection. In addition, this
message could occur when ALTER SYSTEM KILL SESSION or ALTER SYSTEM
DISCONNECT SESSION were issued with the IMMEDIATE qualifier because,
in those cases, the client’s connection to the database is terminated without
waiting for the client to issue a request.

Action: Try again. If the message recurs and the program is user written, check
the program.

Answer 2

都没有连上数据库，怎么执行的sql语句，或者是用到一半断开了。

Answer 3

重新连接数据库

Answer 4

重新登陆
估计在使用的时候，oracle连接断掉了。

Answer 5

未登陆成功,用户密码或者连接服务名有问题
