您需要向DB2Fenced用户和/或DB2Fenced用户所属的组授予权限。例如：

在windows中，问题在于路径访问。
以管理员权限运行db2解决了这个问题（通过更改文件路径也可以解决这个问题）。1。您知道这会将文件写入数据库服务器上的一个目录，对吗？2。该目录必须可由实例的受保护用户写入。755意味着只有目录的所有者才有写权限。我也尝试过给文件夹777，仍然是相同的问题。但是，当我删除admin_cmd时，当我直接从实例运行查询时，它会起作用，但在JDBC连接中不起作用？另外-这是一个通过JDBC或类似DataStudio的东西调用admin\u cmd的自制应用程序吗？@proksch\u ibm我试着用admin\u cmd运行，它给出了错误，但没有admin\u cmd它可以工作。它只是一个简单的Java应用程序。
