plsql不能连接oracle的原因

由 与世无争的帅哥 提交于 2020-03-01 04:00:18
ora-12154原因及解决方法 网上的解决一大片，不外如下： 1.本机的环境变量oracle_home没有设置 2.因为安装过多版本oracle 的原因，plsql中首载入的实例版本不对，解决方法：在登录时，点击取消，工具、首选项，oraclehome选择对应目录及版本。 但是都不是我的菜，最后在把书翻开，看到这么个玩意，才搞定。 Oracle的Net Service在解析连接的时候存在一个Bug，无法解析路径中包括的圆括号。 所以plsql在安装时不要选择带圆括号的。 来源： oschina 链接： https://my.oschina.net/u/99045/blog/49622

ora-12154 could not resolve… with oracle instant client

由 ♀尐吖头ヾ 提交于 2019-12-11 09:19:49
问题 Here are the details: I installed the oracle instant client 11.2.0.2.0 from the OTN download page on a windows 7 64 bit vm (vmware). I am trying to to connect to a remote oracle database, and I can successfully connect with one program using TNS, but not with SQL*Plus and other applications. Trying to connect with SQL*Plus, using schema@servicename, password, etc, gives the above error. To connect via SQL Developer, normally I would use the basic connection info and not rely on tnsnames, but

ODP.NET Managed tnsnames.ora IFILE references

问题 Does Managed ODP.NET x64 12.1.0.2 tnsname.ora support using IFILE?? I cannot get it to work. For example, with the normal "thick client" unmanaged Oracle client that I have had installed for years, I used to have my tnsnames.ora file with one line in it: IFILE=C:\OracleDataSources\tnsnames.MAIN And then the C:\OracleDataSources\tnsnames.MAIN file contains IFILE references to config files that contain the actual data source definitions for each of the other Oracle instances within our

问题 The issue started when i installed the server version with already existing client version of Oracle 10g. Background : The Oracle client version 10g was installed (at c:/oracle) to connect to a database residing in other country. So we can just connect to it and have limited access to it. Path => c:/oracle/ora_client/network/admin/listener.ora So to work as admin I installed 10g server at the same location c:/oracle on windows. I can now work as server. Path => c:/oracle/product/db_1/network

问题 I'm trying to link SQL Server 2005 to an Oracle 10g database.
