数据库升级后出现的问题

kluso

trc文件里面有这样一个错误
The following information assists Oracle in diagnosing
causes of ORA-4031 errors.  This trace may be disabled
by setting the init.ora parameter _4031_dump_bitvec = 0
请牛人指点一下！

数据库产生大量的trace文件主要是什么原因呢？该如何解决呢？还请各位高人多多指教！

你在alertlog贴出些trace 怎么产生的信息

grep "Errors in file" alter*log
