Hi,

I will continue to explain How to Analyze or Interpret an AWR report in Oracle in this article.

 

 

Read first Article before this.

 

 

Host CPU

You can find how many CPUs,Cores and Sockets are there in the Database Server with this section.

Host and Instance CPU Utilization Statistics are also in this section like following.

 

IO Profile

You can find out how much IO ( Total Requests, Database Requests,Database (blocks), Direct (blocks) and etc. ) are there in the Database with this section.

 

Memory Statistics

You can find out the value ( Begin-End)  of the Host Memory, SGA, PGA.

 

Cache Sizes

You can find out the value ( Begin-End)  of the Buffer Cache, Shared Pool and Log Buffer of the Database and the Standard Block Size information

 

Shared Pool Statistics

You can find out some Shared Pool Statistics in this section.

 

Main Report

You can access all sections via using related links in this section.

 

 

 

 

Time Model Statistics

You can find some special statistics in this section like sql execute elapsed time, RMAN cpu time (backup/restore), hard parse elapsed time, PL/SQL execution elapsed time.

These statistics are very important to detect performance problem or load of database.

For example; If RMAN cpu time (backup/restore) is at TOP, then you can change RMAN Backup date as IDLE time of Database like Night.

 

Operating System Statistics

You can find out Average Busy, IDLE, SYS and User time statistics of operating system in this section. Thus, you can decide database busy ? or operating system is busy ?.
