  • Oracle 阻塞(blocking blocked)

       阻塞是DBA经常碰到的情形,尤其是不良的应用程序设计的阻塞将导致性能严重下降直至数据库崩溃。对DBA而言,有必要知道如何定位到当前系统有哪些阻塞,到底谁是阻塞者,谁是被阻塞者。本文对此给出了描述并做了相关演示。1、阻塞及其类型a、什么是阻塞   一个会话持有某个资源的锁,而另一个会话在请求这个资源,就会出现阻塞(blocking)。也就是说新的会话会被挂起,直到持有锁的会话放弃锁定的资源。大多数情况下,在一个交互式应用中被严重阻塞,即可表明应用逻辑有问题,这才是阻塞的根源。b、阻塞得类型   数据库中有5条常见的DML语句可能会阻塞,即:INSERT、UPDATE、DELETE、MERGE 和SELECT FOR UPDATE。2、几种不同类型阻塞的处理办法a、INSERT阻塞主要是由于有一个带主键的表,或者表上有惟一的约束,在两个会话试图用同样的值插入一行时引发阻塞。多表通过引用完整性约束相互链接时,在其依赖的父表正在创建或删除期间,对子表的插入可能会阻塞。对于该类情形建议使用序列来生成主键惟一列值。b、对于UPDATE、DELETE、MERGE 和SELECT FOR UPDATE阻塞,只要有任一session使用这些操作已经锁定行,其余的必须处于等待状态。直到当前锁定行上的锁(排他锁)释放。对于该类情形,建议尽可能快速提交事务,或采用批量SQL方式提交。c、对于一个阻塞的SELECT FOR UPDATE,解决方案很简单:只需增加NOWAIT 子句,它就不会阻塞了。3、演示阻塞--更新表,注,提示符scott@CNMMBO表明用户为scott的session,用户名不同,session不同。scott@CNMMBO> update emp set sal=sal*1.1 where empno=7788; 1 row updated. scott@CNMMBO> @my_env SPID SID SERIAL# USERNAME PROGRAM------------ ---------- ---------- --------------- ------------------------------------------------11205 1073 4642 robin oracle@SZDB (TNS V1-V3) --另起两个session更新同样的行,这两个session都会处于等待,直到第一个session提交或回滚leshami@CNMMBO> update scott.emp set sal=sal+100 where empno=7788; goex_admin@CNMMBO> update scott.emp set sal=sal-50 where empno=7788; --下面在第一个session 查询阻塞情况scott@CNMMBO> @blocker BLOCK_MSG BLOCK-------------------------------------------------- ----------pts5 (1073,4642) is blocking 1067,10438 1pts5 (1073,4642) is blocking 1065,4464 1--上面的结果表明session 1073,4642 阻塞了后面的2个--即session 1073,4642是阻塞者,后面2个session是被阻塞者 --Author : Leshami--Blog : http:blog.csdn.netleshami --下面查询正在阻塞的session id,SQL语句以及被阻塞的时间scott@CNMMBO> @blocking_session_detail.sql SID=||A.SID||WAITCLASS=||A.WAIT_CLASS||TIME=||A.SECONDS_IN_WAIT||CHR(10)||QUERY=||B.SQL_TEXT-------------------------------------------------------------------------------------------------------sid=1067 Wait Class=Application Time=5995 Query=update scott.emp set sal=sal+100 where empno=7788 sid=1065 Wait Class=Application Time=225 Query=update scott.emp set sal=sal-50 where empno=7788 --下面的查询阻塞时锁的持有情况 scott@CNMMBO> @request_lock_type USERNAME SID TY LMODE REQUEST ID1 ID2------------------------------ ---------- -- ----------- ----------- ---------- ----------SCOTT 1073 TX Exclusive None 524319 27412LESHAMI 1067 TX None Exclusive 524319 27412GOEX_ADMIN 1065 TX None Exclusive 524319 27412--可以看到LESHAMI,GOEX_ADMIN 2个用户都在请求52431927412上的Exclusive锁,而此时已经被SCOTT加了Exclusive锁 --查询阻塞时锁的持有详细信息scott@CNMMBO> @request_lock_detail SID USERNAME OSUSER TERMINAL OBJECT_NAME TY Lock Mode Req_Mode---------- -------------------- --------------- ------------------------- -------------------- -- ----------- -------------------- 1065 GOEX_ADMIN robin pts1 EMP TM Row Excl 1065 GOEX_ADMIN robin pts1 Trans-524319 TX --Waiting-- Exclusive 1067 LESHAMI robin pts0 EMP TM Row Excl 1067 LESHAMI robin pts0 Trans-524319 TX --Waiting-- Exclusive 1073 SCOTT robin pts5 EMP TM Row Excl 1073 SCOTT robin pts5 Trans-524319 TX Exclusive 文中涉及到的相关脚本下载:http:download.csdn.netdetailrobinson_06127607033
