我通過ontape -s -L 0做0級備份
現(xiàn)象：
。。。。。。
60 percent done.
Archive failed  function write to tape failed code -1 errno 6
program over


informix下的online.log顯示：
12:03:13  Level 0 Archive started on rootdbs, logdbs, datadbs, rev_premdbs, insu
rdbs
12:08:25  Checkpoint Completed: duration was 0 seconds.

磁帶容量24G,informix下onconfig設(shè)置：
TAPEDEV         /dev/rct0       # Tape device path
TAPEBLK         20              # Tape block size (Kbytes)
TAPESIZE        20480000         # Maximum amount of data to put on tape (Kbytes
)
設(shè)置應(yīng)該正常，0級備份只有中午做失敗，晚上做成功！
原因在SCO上，還是INFORMIX?
請各位幫忙解決！

有點奇怪，晚上做就成功？
是白天應(yīng)用上有什么影響嗎？
幫你頂了。。。
