当前的数据库采用ODM:VERITAS 4.1.20.00 ODM Library, Version 1.1,而在发生错误时等待的是ODM的IO操作。这个错误在MOS甚至是GOOGLE上都找不到,不过可以很容易的判断出,问题发生在Oracle与Veritas之间的配合有关。
发生错误的语句是SELECT COUNT(*) FROM V$LOGMNR_CONTENTS,但是观察会话的历史执行需要,之前已经做过对V$LOGMNR_CONTENTS的全表访问,并未引发异常:

显然这个错误的发生是偶然的,目前并没有导致或解决这个问题的明确方式,不过考虑只是偶尔影响v$logmnr_contents的访问,可以忽略掉这个错误。
