在做database replay预处理的时候遇到一个问题,初略的看,是执行包调用内部(函数/存储过程)出现的错误。感觉是一个典型的传参的错误。 SQL exec dbms_workload_replay.PROCESS_CAPTURE('AAA');BEGIN dbms_workload_replay.PROCESS_CAPTURE('AAA'); END; *ER

这种问题,一般我们都会做10046 trace进一步看调用了那个函数引起的问题。从trace中看到是在运行dbms_wrr_internal.add_capture出的问题。

BEGIN   :1 := dbms_wrr_internal.add_capture( :name,                                        :db_id,                                        :db_name,

                  'TRUE',                                        :status,                                        NULL,

本来以为10046能够把绑定变量这些数值抓出来,但是这里确没有,v$sql_bind_capture也抓不到绑定变量的值。我怀疑和内部的包有关系。所以我们无从判断是哪一个参数的调用类型出了问题。遇到这样的问题也没什么好的办法,以前在自己的Linux环境上搞过database replay,是能够成功的,所以想法就是把Linux上环境的这个包迁移到Hp环境上在试试。于是就用grep去搜索具体是那个文件。搜到了文件名为"prvtwrr.plb"的文件,里面是一堆加密的东西。把这个文件传到HP上运行,运行完后发现,妹的还是报以前的错误。郁闷啊,为什么在我Linux上的环境就可以了,在HP的环境就不行了。走投无路的时候,同事在$ORACLE_HOME目录下面执行了下列命令。

执行find命令居然发现能够找到两个文件,而另外一个文件明眼一看就是补丁文件17411249,赶紧用opatch看了一下补丁的情况。发现这个补丁是最近新装的。

看到了这个信息之后,我们就怀疑是不是安装这个补丁出了问题。如果是的话,我们回退了再试试,于是我们把这个补丁做了一个回退,在readme里面看还要运行一个postinstall.sql脚本,回退完成后在执行预处理的操作发现居然成功了。然后我们再一次安装了这个补丁,运行了postinstall.sql脚本,发现预处理还是成功的。后面问了安装补丁的同事,最终发现是他忘记了执行postinstall.sql脚本。总的来说,这个故事还是很丧心病狂的,如果不去执行一把find命令,根本就不会发现是因为安装了新补丁造成的错误。
