ORACLE排错记录

1、使用backup archivelog all format '/tmp/oracle/log_arch_%U' delete input;RMAN备份时提示：

RMAN-03009: failure of backup command on ORA_DISK_1 channel at 01/01/2014 11:07:18

ORA-19502: write error on file "/tmp/oracle/log_arch_0hosvi0g_1_1", blockno 1855489 (blocksize=512)

ORA-27072: File I/O error

Linux-x86_64 Error: 2: No such file or directory

Additional information: 4

Additional information: 1855489

Additional information: 577024

解决方法：

起初闪回区空间2G，used 1.5G，怀疑是闪回区空间不足，于是alter system set db_recovery_file_dest_size=6G；但还是不行查询v$recovery_file_dest,v$flash_recovery_area_usage等视图！未找出什么原因，后来想到使用format时，是否应该先创建目录，create directory dir_test as '/tmp/oracle'; 后再使用上述语句备份成功！
