最近中联服务器配置工具一直进不了,提示:ORA-12538: TNS: no such protocol adapter,网上找了一圈,也没有找了多种方法,也没有解决,看到这篇日志:服务器
http://www.dba-oracle.com/t_iora_12538_tns_no_protocol_adapter.htm,看到最后:oracle
Solutions:工具
If TNS_ADMIN is set then you should be able to use a network alias, not the full "(DESCRIPTION..." connect string. The TNS_ADMIN parm tells Oracle clients where to find the tnsnames.ora file.this
Setting the ORACLE_HOME environment variable incorrectly on a Windows based system will create this problem.
由于机器装了oracle8i的一个简易客户端,一个oracle 11g服务端,把ORACLE_HOME设置成了oracle 11g的主目录,试着删除,就能够了。解决!!!!!!!!spa
