Oracle数据库是一个非常重要的数据库系统,在其使用过程中会遇到许多的问题和错误。其中,Oracle 12506和01019错误是比较常见的问题之一。
首先,让我们来看看Oracle 12506错误。这个错误通常会在用户试图连接到数据库时出现。可能的原因有很多,例如网络问题、数据库实例是否可用以及配置问题等等。以下是一个示例:
ERROR:
ORA-12516: TNS:listener could not find available handler with
matching protocol stack
12516, 00000, "TNS:listener could not find available handler with\nmatching protocol stack"
// *Cause: None of the known and available service handlers for the
requested protocol stack are appropriate for the client connection.
// *Action: Check to see if the CONNECT_DATA was correct and adjust
the protocol parameter if necessary. Also, check to see if the
service handler is operational by trying to start it. 本文链接:https://my.lmcjl.com/post/13121.html
