很多oracle产品都有自己的TNS文件,如果你的系统里装了多个Oracle的产品的话,那么客户端连instance的时候,到底是使用那个tnsnames.ora呢?这个时候就需要看TNS_ADMIN这个参数了。
The tns_admin parameter is super useful on servers with many databases on different release levels (hence different $ORACLE_HOME directories) because all databases tns_admin values can be set to a single location, allowing a single set of SQL*Net files for all databases on the server.
Without the tns_admin variable, each instance would have it‘s own set of TNS files in the $ORACLE_HOME/network/admin directory.
