所以我用openSUSE复制了一个正在运行的VM。当我启动机器时,我总是像lsnrctrl start
一样,然后一切正常。通常我得到以下输出:
# lsnrctl status

我的XE实例在很久以后就开始了。但后来XE出现了,就像我说的,一切正常。现在我做了同样的事,但我的XE服务还没有结束。

ERROR:
ORA-12514: TNS:listener does not currently know of service requested in connect
descriptor
运行我的perl脚本时,我得到:
AH01215: DBI connect('XE','username',...) failed: ORA-12514: TNS:listener does not currently know of service requested in connect descriptor (DBD ERROR: OCIServerAttach) at /srv/www/cgi-bin/lib/myfunctions.pm line 372., referer: http://192.168.0.13/
我不知道这里发生了什么,有人能帮助我吗?需要完成一些事情:/
答案 0 :(得分:0)
我不知道到底出了什么问题,我现在已经使用这台VM近一年了。无论如何,我现在很沮丧,我只是使用http://www.dba-oracle.com/t_sample_listener_ora_files.htm创建了一个新的listener.ora。现在一切似乎都有效。
