informix資料庫頁故障的處理方法

1，在做資料庫全備的時候出現下列錯誤：
16:28:45 Assert Warning: Archive detects that page 7:45157032 is corrupt.
16:28:45 IBM Informix Dynamic Server Version 10.00.UC4

2，執行oncheck -pe 檢測這個頁所屬的資料空間
[informix@tonykorn ~]$ oncheck -pe datadbs2 > datadbs2_oncheck_20080827.log
[informix@tonykorn ~]$

3，根據日誌內容檢視當時錯誤頁所屬的表：
rrldbshop:'informix'.pdykcostitem 45143269 2048
rrldbshop:'informix'.pdgoodscost 45145317 8192
rrldbshop:'informix'.syslog 45153509 8192
rrldbshop:'informix'.pdgoodsitem 45161701 8192

透過上面可以得到45157032和45157033的頁都屬於syslog表

4,執行oncheck -cd 檢測一下這個表的資訊
[informix@tonykorn ~]$ oncheck -cd rrldbshop:syslog

TBLspace data check for rrldbshop:informix.syslog
