<title>Configure Disk Storage for Oracle CRS and Database Files</title>
<description> You do not have to use the same storage option for each type of file; Before you install Oracle Cluster Ready Services, you must choose the storage option that you want to use for the Oracle Cluster Registry and CRS voting disk. You cannot use Automatic Storage Management to store these files If you are not using HACMP, you must use a GPFS file system to store the Oracle CRS files</description>

<title>表行删除后再插入相同的行，该插入的行会使用原先行所在的块吗？</title>
<description>http://www.itpub.net/thread-1048829-1-1.html不一定，有可能删除行所在的块又被放入了其他的行数据或者相同的行被插入其他数据块主要看freelist的排列，当进行插入操作时，oracle会将数据放入队列中第一个满足空间要求的块。你应该是在删除操作之后紧接着就进行插入吧这样经过删除操作的块将位于freelist队列的头部当进行插入操作时，oracle就很自然的会把数据插入原来的块中</description>

where username = 'HR'传输 AWR 数据
假设您要尝试解决生产数据库中的某些性能问题。本文有一部分已经说明了 AWR 数据对于分析是很重要的。但在正常的生产期间分析 AWR 数据可能并不合适，甚至是不可行的。相反，您可能希望将数据加载到某个中心位置以进行比较分析。如何完成该任务呢？ Oracle 数据库 10g 第 2 版中提供了一个用于此目的的新程序包 DBMS_SWRF_INTERNAL。要将它下载到 Data Pump 转储文件，您将使用过程 AWR_EXTR...</description>
