Plsql 使用数据泵API的备份过程
您好，我尝试创建Oracle过程，该过程从用户模式（POSData）获取备份，并将其放置在名为“Backups”的目录中，POSData使用系统用户提供的代码在目录“Backups”上进行读写操作Plsql 使用数据泵API的备份过程,plsql,oracle11g,Plsql,Oracle11g,您好，我尝试创建Oracle过程，该过程从用户模式（POSData）获取备份，并将其放置在名为“Backups”的目录中，POSData使用系统用户提供的代码在目录“Backups”上进行读写操作 DECLARE h2 NUMBER; BEGIN h2 := DBMS_DATAPUMP.OPEN('EXPORT', 'SCHEMA'); DBMS_DATAPUMP.ADD_FILE(h2,'POSData.dmp','Backups'); DBMS_DATAPUMP.ME

DBMS_DATAPUMP.GET_STATUS will further describe the error.
*Action: Correct the bad argument and retry the API.
请帮助？DBMS\u数据泵有一些非常好的错误消息，但您必须深入了解它们。在下面的示例中，我添加了一个嵌套过程output_expdp_error来转储详细消息。当然，您应该对此进行修改，以便为您的环境执行适当的日志记录：

我找到了问题的解决方案，这里是代码

模式名称是否大写，此处：
DBMS\u DATAPUMP.METADATA\u过滤器（h2，'schema\u EXP'，'in（'POSDATA'）帮助？不幸的是，同样的问题。我注意到“DBMS_DATAPUMP.ADD_FILE（h2，'POSData.dmp'，'Backups'）；”行中的问题，但我不知道为什么？
