我有两个数据库，主要和次要以及两者之间配置的数据保护，我重新启动了suse linux但是在启动数据库时，复制没有完成，我想我采取了错误的方式来启动备用数据库....不，它只是挂载，我有一个不能在备用间隙表中检测到的间隙，以及备用数据库中的“无FAL服务器指定”问题，可能是什么错误？

您需要在init文件或spfile（sqlplus）中设置参数
在主数据库中：
FAL_SERVER='standby_database'
FAL_CLIENT='primary_database'
在备用数据库中：
FAL_SERVER='primary_database'
FAL_CLIENT='standby_database'
获取存档日志文件需要这两个参数（FAL表示Fetch ArchiveLog）。
希望我帮助你。

这个问题是5岁，但我觉得还没有完全回答。
首先，oracle如何解决这个差距：
MRP流程是触发GAP请求的流程。该过程如下所示：没有备用重做日志：alter database recover managed standby database disconnect;使用备用重做：使用当前日志文件断开连接更改数据库恢复受管备用数据库;
如果主数据库只有一个备用数据库，则实际上不需要配置fal_server和fal_client参数。
如果缺少fal_server，oracle将从log_archive_dest_n中获取该信息。
这意味着还需要在备用数据库上配置log_archive_dest_2。
那么如何解决GAP解决问题：
MRP流程每隔一段时间就会发送一次GAP解析请求。如果您想立即获取它以确保它正常工作：SQL> alter database recover managed standby database cancel; SQL> alter database使用当前日志文件恢复托管备用数据库; （使用备用重做日志，它在备用时更快地应用日志）
如果要设置级联备用设置，则实际存在fal_server和fal_client参数。
主数据库A将存档日志发送到备用B如果备用B变为主数据库，则将存档日志发送到备用数据库C.
11.2上的FAL行为（Doc ID 1394472.1）
从11.2开始，无需提及FAL_CLIENT primary将从log_archive_dest_n（从它收到FAL请求的远程目标备用服务器）服务中获取它。
