查看trace文件nc_arc0_177356.trc得知，从11月11日上午10点14分开始报错，也是类似的提示，再目标主机无法创建归档日志文件，平均1分钟报一次错误，在备库查看，发现原来是因为没有定期清理主库传递过来的归档日志，磁盘空间耗尽了！
70G空间全部用完了，由于客户的磁盘本来就比较小，其中一部分还用来存放数据文件，本身就要占用47G。
最后一个归档日志是11月11日，7:25生成的，后面就没有了，这和trace文件中的报错也是符合的，由于这个时刻耗尽了磁盘的最后一些空间，进而造成了主库报警日志中出现的无法创建远程归档的错误，既然找到问题了，那么处理就容易了，先把备库应用过的归档删除掉，释放磁盘空间。
由于备库归档存在GAP，并且这些GAP在主库的归档中也已经没有了，主库并没有保留非常多的归档，切归档日志也没有单独做备份集，因此只能是重新配置DG Configuration。
今天过去客户那边，把DG重新配置了一下。步骤其实很简单，因为之前已经配置过一次，这次只要是同步一下就行了，不需要修改参数，拷贝参数文件、密码文件、tnsnames.ora、listener.Z??http://www.2cto.com/kf/ware/vc/" target="_blank" class="keylink">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
