  DB Time不包括Oracle后台进程消耗的时间。如果DBTime远远小于Elapsed时间,说明数据库比较空闲。
  在79分钟里(其间收集了3次快照数据),数据库耗时11分钟,RDA数据中显示系统有8个逻辑CPU(4个物理CPU),平均每个CPU耗时1.4分钟,CPU利用率只有大约2%(1.4/79)。说明系统压力非常小。
  可是对于批量系统,数据库的工作负载总是集中在一段时间内。如果快照周期不在这一段时间内,或者快照周期跨度太长而包含了大量的数据库空闲时间,所得出的分析结果是没有意义的。这也说明选择分析时间段很关键,要选择能够代表性能问题的时间段。

  显示SGA中每个区域的大小(在AMM改变它们之后),可用来与初始参数值比较。
  shared pool主要包括library cache和dictionary cache。librarycache用来存储最近解析(或编译)后SQL、PL/SQL和Java classes等。librarycache用来存储最近引用的数据字典。发生在library cache或dictionary cache的cachemiss代价要比发生在buffer cache的代价高得多。因此sharedpool的设置要确保最近使用的数据都能被cache。

  显示数据库负载概况,将之与基线数据比较才具有更多的意义,如果每秒或每事务的负载变化不大,说明应用运行比较稳定。单个的报告数据只说明应用的负载情况,绝大多数据并没有一个所谓“正确”的值,然而Logons大于每秒1~2个、Hardparses大于每秒100、全部parses超过每秒300表明可能有争用问题。
  Redo size:每秒/每事务产生的redo大小(单位字节),可标志数据库任务的繁重程序。
  Logical reads:每秒/每事务逻辑读的块数
  Block changes:每秒/每事务修改的块数
  Physical reads:每秒/每事务物理读的块数
  Physical writes:每秒/每事务物理写的块数
  User calls:每秒/每事务用户call次数
  Parses:SQL解析的次数
  Hard parses:其中硬解析的次数,硬解析太多,说明SQL重用率不高。
  Sorts:每秒/每事务的排序次数
  Logons:每秒/每事务登录的次数
  Executes:每秒/每事务SQL执行次数
  Transactions:每秒事务数
  Blocks changed per Read:表示逻辑读用于修改数据块的比例
  Recursive Call:递归调用占所有操作的比率
  Rollback per transaction:每事务的回滚率
  Rows per Sort:每次排序的行数
  注:
  Oracle的硬解析和软解析
  提到软解析(soft parse)和硬解析(hardparse),就不能不说一下Oracle对sql的处理过程。当你发出一条sql语句交付Oracle,在执行和获取结果前,Oracle对此sql将进行几个步骤的处理过程:
  1、语法检查(syntax check)
  检查此sql的拼写是否语法。
  2、语义检查(semantic check)
  诸如检查sql语句中的访问对象是否存在及该用户是否具备相应的权限。
  3、对sql语句进行解析(parse)
  利用内部算法对sql进行解析,生成解析树(parse tree)及执行计划(execution plan)。
  4、执行sql,返回结果(execute and return)
  其中,软、硬解析就发生在第三个过程里。
  Oracle利用内部的hash算法来取得该sql的hash值,然后在librarycache里查找是否存在该hash值;
  假设存在,则将此sql与cache中的进行比较;
  假设“相同”,就将利用已有的解析树与执行计划,而省略了优化器的相关工作。这也就是软解析的过程。
  诚然,如果上面的2个假设中任有一个不成立,那么优化器都将进行创建解析树、生成执行计划的动作。这个过程就叫硬解析。
  创建解析树、生成执行计划对于sql的执行来说是开销昂贵的动作,所以,应当极力避免硬解析,尽量使用软解析。

  本节包含了Oracle关键指标的内存命中率及其它数据库实例操作的效率。其中Buffer Hit Ratio 也称CacheHit Ratio,Library Hit ratio也称Library Cache Hit ratio。同LoadProfile一节相同,这一节也没有所谓“正确”的值,而只能根据应用的特点判断是否合适。在一个使用直接读执行大型并行查询的DSS环境,20%的BufferHit Ratio是可以接受的,而这个值对于一个OLTP系统是完全不能接受的。根据Oracle的经验,对于OLTPT系统,BufferHit Ratio理想应该在90%以上。
  Buffer Nowait表示在内存获得数据的未等待比例。
  bufferhit表示进程从内存中找到数据块的比率,监视这个值是否发生重大变化比这个值本身更重要。对于一般的OLTP系统,如果此值低于80%,应该给数据库分配更多的内存。
  Redo NoWait表示在LOG缓冲区获得BUFFER的未等待比例。如果太低(可参考90%阀值),考虑增加LOGBUFFER。
  library hit表示Oracle从LibraryCache中检索到一个解析过的SQL或PL/SQL语句的比率,当应用程序调用SQL或存储过程时,Oracle检查LibraryCache确定是否存在解析过的版本,如果存在,Oracle立即执行语句;如果不存在,Oracle解析此语句,并在LibraryCache中为它分配共享SQL区。低的library hit ratio会导致过多的解析,增加CPU消耗,降低性能。如果libraryhit ratio低于90%,可能需要调大shared pool区。
  Latch Hit:Latch是一种保护内存结构的锁,可以认为是SERVER进程获取访问内存数据结构的许可。要确保LatchHit>99%,否则意味着Shared Poollatch争用,可能由于未共享的SQL,或者Library Cache太小,可使用绑定变更或调大Shared Pool解决。
  Parse CPU to ParseElapsd:解析实际运行时间/(解析实际运行时间+解析中等待资源时间),越高越好。
  Non-Parse CPU :SQL实际运行时间/(SQL实际运行时间+SQL解析时间),太低表示解析消耗时间过多。
  Execute toParse:是语句执行与分析的比例,如果要SQL重用率高,则这个比例会很高。该值越高表示一次解析后被重复执行的次数越多。
  In-memory Sort:在内存中排序的比率,如果过低说明有大量的排序在临时表空间中进行。考虑调大PGA。
  SoftParse:软解析的百分比(softs/softs+hards),近似当作sql在共享区的命中率,太低则需要调整应用使用绑定变量。

  Memory Usage%:对于一个已经运行一段时间的数据库来说,共享池内存使用率,应该稳定在75%-90%间,如果太小,说明SharedPool有浪费,而如果高于90,说明共享池中有争用,内存不足。
  SQL withexecutions>1:执行次数大于1的sql比率,如果此值太小,说明需要在应用中更多使用绑定变量,避免过多SQL解析。
  Memory for SQL w/exec>1:执行次数大于1的SQL消耗内存的占比。

  这是报告概要的最后一节,显示了系统中最严重的5个等待,按所占等待时间的比例倒序列示。当我们调优时,总希望观察到最显著的效果,因此应当从这里入手确定我们下一步做什么。例如如果‘bufferbusy wait’是较严重的等待事件,我们应当继续研究报告中Buffer Wait和File/TablespaceIO区的内容,识别哪些文件导致了问题。如果最严重的等待事件是I/O事件,我们应当研究按物理读排序的SQL语句区以识别哪些语句在执行大量I/O,并研究Tablespace和I/O区观察较慢响应时间的文件。如果有较高的LATCH等待,就需要察看详细的LATCH统计识别哪些LATCH产生的问题。
  在这里,log file parallel write是相对比较多的等待,占用了7%的CPU时间。
  通常,在没有问题的数据库中,CPU time总是列在第一个。
  更多的等待事件,参见本报告 的Wait Events一节。

  db file scattered read等待事件是当SESSION等待multi-blockI/O时发生的,通过是由于full table scans或 index fast fullscans。发生过多读操作的Segments可以在“Segments by Physical Reads”和 “SQL orderedbyReads”节中识别(在其它版本的报告中,可能是别的名称)。如果在OLTP应用中,不应该有过多的全扫描操作,而应使用选择性好的索引操作。
  DB file sequentialread等待意味着发生顺序I/O读等待(通常是单块读取到连续的内存区域中),如果这个等待非常严重,应该使用上一段的方法确定执行读操作的热点SEGMENT,然后通过对大表进行分区以减少I/O量,或者优化执行计划(通过使用存储大纲或执行数据分析)以避免单块读操作引起的sequentialread等待。通过在批量应用中,DB file sequential read是很影响性能的事件,总是应当设法避免。
  Log File Parallel Write事件是在等待LGWR进程将REDO记录从LOG缓冲区写到联机日志文件时发生的。虽然写操作可能是并发的,但LGWR需要等待最后的I/O写到磁盘上才能认为并行写的完成,因此等待时间依赖于OS完成所有请求的时间。如果这个等待比较严重,可以通过将LOG文件移到更快的磁盘上或者条带化磁盘(减少争用)而降低这个等待。
  Buffer Busy Waits事件是在一个SESSION需要访问BUFFERCACHE中的一个数据库块而又不能访问时发生的。缓冲区“busy”的两个原因是:1)另一个SESSION正在将数据块读进BUFFER。2)另一个SESSION正在以排它模式占用着这块被请求的BUFFER。可以在“Segmentsby Buffer Busy Waits”一节中找出发生这种等待的SEGMENT,然后通过使用reverse-keyindexes并对热表进行分区而减少这种等待事件。
  Log File Sync事件,当用户SESSION执行事务操作(COMMIT或ROLLBACK等)后,会通知LGWR进程将所需要的所有REDO信息从LOGBUFFER写到LOG文件,在用户SESSION等待LGWR返回安全写入磁盘的通知时发生此等待。减少此等待的方法写Log FileParallel Write事件的处理。
  EnqueueWaits是串行访问本地资源的本锁,表明正在等待一个被其它SESSION(一个或多个)以排它模式锁住的资源。减少这种等待的方法依赖于生产等待的锁类型。导致Enqueue等待的主要锁类型有三种:TX(事务锁),TM D(ML锁)和ST(空间管理锁)。

  • SQL ordered by CPU Time
  • SQL ordered by Gets
  • SQL ordered by Reads
  • SQL ordered by Executions
  • SQL ordered by Parse Calls
  • SQL ordered by Sharable Memory
  • SQL ordered by Version Count
  • SQL ordered by Cluster Wait Time
  • Complete List of SQL Text
  本节按各种资源分别列出对资源消耗最严重的SQL语句,并显示它们所占统计期内全部资源的比例,这给出我们调优指南。例如在一个系统中,CPU资源是系统性能瓶颈所在,那么优化buffergets最多的SQL语句将获得最大效果。在一个I/O等待是最严重事件的系统中,调优的目标应该是physicalIOs最多的SQL语句。
  在STATSPACK报告中,没有完整的SQL语句,可使用报告中的Hash Value通过下面语句从数据库中查到:
  select sql_text
  from stats$sqltext
  where hash_value = &hash_value
  order by piece;
