  Hello

  How to create an Oracle AWR and ADDM report for a multiple instance (RAC) Oracle database 11 g 2?

  Concerning

  Hello

  Oracle DB 11 g 2 AWR Global report before 11 GR 2, the awrrpt.sql generation

  under $ORACLE_HOME/rdbms/admin only generates the report awr for the local instance.

  You will need to collect for each RAC instance awr report.

  11 GR 2, there are two new scripts awrgrpt.sql AND awrgdrpt.sql for CARS

  awrgrpt. SQL - AWR Global report (RAC) (global report)

  awrgdrpt. SQL - overall Diff AWR (RAC) report.

  Some other important scripts under $ORACLE_HOME/rdbms/admin

  spawrrac. SQL - Server Performance RAC report

  awrsqrpt. SQL - statement of the standard ANSI SQL92 report

  awrddrpt. SQL - period diff on the current instance

  awrrpti. SQL - workload repository Instance (RAC) report

• Review of details of AWR and ASH reports

  Hello...
  
  is there than a documentation on AWR and ASH reports so that the report is studied in detail...
  
  For an example
  
  IN the report of the ASH
  
  If you take Section TOP SQL with TOP events section...
  
  There are number of columns such as SQLID, Planhash, sampled # executions, % activity, event, high-ranking Source, TEXT SQL
  
  Here this column sampled number of executions a number of times where SQL has been executed... right...?
  and another high-ranking Source column wrote his ACCESS TABLE - FULL or any group by clause etc.
  
  In the example above, just like that I want to study in detail with each section of the AWR and ASH report
  
  See you soon...

  Hello

  I have a few articles abour AWR in my blog:

  http://Savvinov.com/2012/09/10/a-map-to-AWR-report/

  Maybe they can help you to a certain extent.

  However, you must understand is no detailed instructions on reading AWR, because:

  (1) AWR is just a collection of performance statistics, so read requires an understanding Oracle performance and how it is measured rather something specific to CWA

  (2) practical experience is most important theoretical knowledge of tham

  Hello
  You can try to reduce the channels and the degree of parallel...

  Is backup optimization on?

• AWR and dba_feature_usage_statistics

  Hi gurus.
  
  Important information about the license found below.
  http://download-East.Oracle.com/docs/CD/B19306_01/license.102/b14199/options.htm#CIHJJBGA
  
  It is said that the use of AWR has (to access v$ active_session_history, dba_hist_xxxxxxx, oracle_home/rdbms/admin/awr*.sql, etc.), we need extra license, correct?
  
  After that I installed enterprise edition and set up EM (not in the grid) for test, I have questions
  1. I checked "remove access" on the screen to access the configuration menu of the EM management pack.
  but I can always find all views (dba_hist_xxx, v$ active_session_history, etc...) on CWA.
  is this correct?
  
  2. I ran a $ORACLE_HOME/rdbms/admin/awrrpt.sql script, but I can always find that the value of the column "Currently_Used" of the name 'Automatic workload repository' the view 'dba_feature_usage_statistics' always is 'FALSE. '
  is this correct?
  
  Thank you.

  Yes--or need to license (available only for Enterprise Edition) diagnostics pack

  Yes. It does display in EM. Given that some of these views are also used for other things internally, it does not remove them. You get NO points of view.

• Performance of the database

  Hello
  I have an interesting question here. I have a database of size 80 GB its actuallty a Peoplesoft DB (Remember:Peoplesoft DB is null goal year Oracle DB). I have 120 users accessing it. We have a server of DB with 16 GB of RAM and CPU 8 - core. How to calculate the size to be allocated to the LMS No.. DB writer process required etc... To be short, I would like to have a list of init parameters that would make my DB more quickly. Thanks in advance.

  If you are on 10g or go, you can get help from the oracle Advisor to set your PGA and the LMS.

  V$ sga_target_advice

  in 10g, you can also generate a report AWR and ADDM for details and advice on the performance of the oracle.

• Bug? : cannot execute predefined "last awr" report with the latest version of the SQL Developer

  Using sql developer before 4.x... report works fine

  Using SQL developer 4.0.0.13... report fails with ORA-01422

  using the actual query to generate awr against the same range of component snap works perfectly

  I opened a SR on the question

  Thank you

  It's always a good idea to open a SR when you are able.  I assume that you have already received a response from support.  For others I wondered about this, the question is likely related to running the report against a CCR environment, as indicated in the following bug:

  Bug 18132564 - LAST AWR REPORT FAILS WITH ORA-01422 IN CCR ENVIRONMENTS
  

  The call of the AWR report requires parameters for a DB and an ID of Instance, so that the report should run, as in earlier versions, for only the current instance, or be modified to run all instances in the cluster.

  Kind regards

  P.S.: And, in fact, a discussion prior forum - ai2 4.0-AWR and ASH giving ora-01427

  lead following bugs are connected and supposed to be fixed for SQL Developer 4.0...

  
  

  Bug 17481944 - PERFORMANCE PANELS NEED AWR/ASH/ADDM FOR RAC ENVIRONMENTS SUPPORT

  
  

  ... with the developer commenting

  I've added a number instance selection control to the various reports: ASH,.
  AWR, difference and SQL. The control is supposed to be visible when the
  connection is a RAC system, tests should a RAC.

  So if you are not on a RAC system, or are on CARS but do not see the selection number instance control, please let us know.

• AWR files in oracle

  Hello
  I use AWR reports feature in ORACLE 11 g to get the vital for my application ststiatics. However in SQL sorted by elapsed time, I get a lot of queries table SYS. Please help me with the settings to get the specific schema queries only.

  You may be using the wrong tool?

  A report at the level of the system as AWR or ADDM isn't any use to you, if your application code is not significant at the level of the system.

  You might want to review the follow-up of your application sessions using client_id or module to identify these sessions owned by your application, and then possibly use TRCSESS and TKPROF.

• Load data to the warehouse of the AWR problem

  Hello!

  I started to use warehouse AWR and especially database loaded successfully.

  But a few DB, there is problem, here is the output of 'Instant download now' job:

  SQL > SQL > SQL > BEGIN dbsnmp.mgmt_caw_extract.run_job_now; END;

  *

  ERROR on line 1:

  ORA-20137: NO NEWS EXTRACT SNAPSHOTS

  ORA-06512: at «DBSNMP.» MGMT_CAW_EXTRACT', line 528

  ORA-06512: at line 1

  Someone at - it experience with similar problems?

  Problem solved. things to check:

  -parameter job_queue_processes > 0, scheduller work MGMT_CAW_EXTRACT must run every 3 hours.

  -CAW_EXTRACT directory must exist and point to the directory in the directory agent 12 c.

  Dbsnmo.mgmt_caw_extract.run_extract of procedure can be executed manually first, after that this download job runs successfully.

• Can we all define the difference of hard and soft analysis the analysis

  Can we all define the difference of hard and soft analysis the analysis coming in SQL tuning advisor and ADDM recommendations.

  To improve the same needs to be done. Please advise on the same.

  Thank you

  What is analysis?

  -> any query SQL under validation goes to the shared pool

  Validation: check the syntax, semantic check, etc...

  Hard analysis SQL going for below in the shared pool

  Syntax

  Semantics

  Transformation of the query

  Optimization

  Create an executable

  E/S

  soft analysis (reduced time spent by jumping the redundant task)

  Transformation of the query

• How to find the sql queries executed in one day with the sql and runtime text

  Hi Experts,

  Please tell me the sql query to find out the queries executed on a particular day and the runtime and the sql text of the query.

  Please reply urgent.

  Thanks in advance

  Database instance 'A' may have run 100 SQL queries today.  As for the instance of database 'B' could have exploited queries SQL 1 million today.  Instance of database 'B' to 'keep' the 1 million SQL statements - in memory or on disk do you expect?  Of course not.  There the age or flush or invalidate memory SQL statements.  He can't keep them on the disk (imagine running a completely different set of 1.2million SQL statements tomorrow and 1.3 the next day).

  AWR and StatsPack can make counts the number of "n" top of the page ("n" default to 30) SQL statements which are still present in the cache of the library (not years, rinsed, invalidated) when a snapshot was taken.  They can't declare "all" SQL statements.

  To return to your needs.  WHY do you need all the SQL statements?  Or are there only certain operations specific SQL would you be interested?  Could they have been treated by allowing audit (for example, UPDATE and DELETE with EXTENDED verification instructions)?
