请教关于oracle补丁的一个问题：
You must have NO OTHER PATCHES installed on
your Oracle Server since the latest patch set
这是什么意思呢？没有读懂。
------------------------------------
#- Your system configuration (Oracle Server version and patch
#level, OS Version) must exactly match those in the bug
#database entry - You must have NO OTHER PATCHES installed on
#your Oracle Server since the latest patch set (or base release
#x.y.z if you have no patch sets installed).
