64位 Win7 下 Toad for Oracle 10.5 连接Oracle10g
如题,64位 Win7 下 Toad for Oracle 10.5 连接Oracle10g。
Toad可以读取Tnsnames.ora的配置,但是当录入帐号、口令,点击Connect时提示:
Ora-12154:TNS:无法解析指定的连接描述符。
请帮忙,谢谢!
------解决方案--------------------检查输入的服务名与配置的服务名是否一致。另外注意生成的本地服务名文件(Windows下如D:oracleora92networkadmin tnsnames.ora,Linux/Unix下/network/admin/tnsnames.ora)里每项服务的首 行服务名称前不能有空格。
------解决方案--------------------如果你很确定不是以上问题,自己按照这个步骤检查一下
[oracle@localhost ~]$ oerr ora 12154
12154, 00000, "TNS:could not resolve the connect identifier specified"
// *Cause: A connection to a database or other service was requested using
// a connect identifier, and the connect identifier specified could not
// be resolved into a connect descriptor using one of the naming methods
// configured. For example, if the type of connect identifier used was a
// net service name then the net service name could not be found in a
// naming method repository, or the repository could not be
// located or reached.
// *Action:
// - If you are using local naming (TNSNAMES.ORA file):
// - Make sure that "TNSNAMES" is listed as one of the values of the
// NAMES.DIRECTORY_PATH parameter in the Oracle Net profile
// (SQLNET.ORA)
// - Verify that a TNSNAMES.ORA file exists and is in the proper
// directory and is accessible.
// - Check that the net service name used as the connect identifier
// exists in the TNSNAMES.ORA file.
// - Make sure there are no syntax errors anywhere in the TNSNAMES.ORA
// file. Look for unmatched parentheses or stray characters. Errors
// in a TNSNAMES.ORA file may make it unusable.
// - If you are using directory naming:
// - Verify that "LDAP" is listed as one of the values of the
// NAMES.DIRETORY_PATH parameter in the Oracle Net profile
// (SQLNET.ORA).
// - Verify that the LDAP directory server is up and that it is
// accessible.
// - Verify that the net service name or database name used as&nb
