kewastUnPackStats(): bad magic 1 (0x1109fe0c2, 0)
kewastUnPackStats(): bad magic 1 (0x1109fe0c2, 0)
環境：
Oracle 11.2.0.1 單例項環境
Aix 6.1
Asm
原因：
這是一個已知BUG導致的，主要是由於升級到11g後的一些變更導致的，
處理
文件提示，這是由於ASH資訊讀取出錯導致的：
It is caused by the variable part of the Active Session History rows (the moduile, action program, etc. information) not being stored properly, causing any read-back of this data through views like (G)V$ACTIVE_SESSION_HISTORY to fail.
該BUG不會引起嚴重問題，在Oracle Database 12c或者11.2.0.2之後的補丁集中被修正。
