我已建立一个服务gliot,但我用pb连上去,创建了一个表,在sql plus8.0中删除不了,好像设置了ipsec,连不上了,又去掉设置,现在创建一个服务时,选择localdatabase,或127.0.01会出现以下错误:
The test did not succeed.
ORA-12203: TNS:unable to connect to destination
There may be an error in the fields entered
or the server may not be ready for a connection.
You can check the server and retry, or continue.
请问是什么错误?
