Ora-03114:未连接数据库
现象: 在使用pl/sql developer编译时总是报 Ora-03114:未连接数据库。
解决方法:
故障原因:PLSQLDev.exe程序和Oracle数据库的CDC功能产生冲突;使用TOAD,OEM等其他客户端工具则不会有以上情况。
操作为:
DROP TRIGGER sys.cdc_alter_ctable_before;
DROP TRIGGER sys.cdc_create_ctable_after;
DROP TRIGGER sys.cdc_create_ctable_before ;
DROP TRIGGER sys.cdc_drop_ctable_before;
做以上操作就可以编译了,如果还是不可以编译,就再执行如下的语句
CALL sys.dbms_java.dropjava('-s rdbms/jlib/CDC.jar');
Oracle CDC简介
官方文档说明:
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.
