• Generate Statspack report automatically once a day

  Hello
  
  I would like to generate statspack report once per day and send automatically to my emial to important parts of this report. Right now I have this sript:

  su - oracle -c "sqlplus perfstat/perfstat" << EOF
  column esnap new_value end_snap noprint
  select max(snap_id) as esnap from stats$snapshot;
  column bsnap new_value begin_snap noprint
  select max(snap_id)-24 as bsnap from stats$snapshot;
  define report_name=/home/oracle/sp_proba.lst
  @?/rdbms/admin/spreport
  EOF

  Of course I remove the lines below that parse and send information to my email. It is important to me that those command works when I paste the line in perfstat session (from sqlplus), but when I run the script it receive an error ORA-20200. Of course, it is obvious that this snap_id exists because I select in statspack view! Question is, why this code works when I run line by line of sqlplus session, but does not work when run from a script? Someone at - it such a problem?
  
  Best.

  try putting a------before instant stats$ $

  column esnap new_value end_snap noprint
  Select max (snap_id) as snapshot esnap of $ stats\;
  column bsnap new_value begin_snap noprint
  SELECT max (snap_id) - 24 as bsnap of snapshot of $ stats\;
  define report_name=/home/oracle/sp_proba.lst

  Hi guys.
  Is there a way I can change something, so my sql statements are not truncated in the statspack report?

• How to read the Statspack report in Oracle 11.2 g Standard Edition

  Dear all,
  
  I use Oracle 11.2 g Standard Edition in the laboratory.
  
  For the performance tuning, how to read the Statspack report?
  
  Please note I cannot use the feature of Oracle AWR due to the Limitation of the license. Thus, as if I will generate report AWR with Oracle Standard Edition, it will be not correct error and printing "time DB is equal to zero for any report interval."
  
  Sumit-
  Bangalore, India

  The CWA requires additional licenses - Oracle's Diagnostics Pack.
  http://download.Oracle.com/docs/CD/E11882_01/license.112/e10594/options.htm#CIHIHDDJ

  This is only available for the Enterprise Edition licenses on top. I don't know anyway to the CWA standard edition licenses, so I recommend against using it even where it does not on its own.

• Find the sql query in statspack report

  so the question is find this query which is kiiled by admin?
  
  Thank you

  Hello

  Its bad news to can not find this sql... So normally it istn killed by admin, I could find it from stats$ sql_summary or v$ sql_text?

  It is possible.

  And another question... If I have a sql printing is eating my cpu or my server resource, how do I find this sql? Under what title I can find in the statspack report

  Refer to:

• How can I save an AWR/statspack report in xml format?

  How can I save an AWR/statspack report in xml format? or is there a way... coz when you create the report, it offers the possibility for normal (the base sql or txt file) or html... of 10.2.0.3

  Hello

  H4. No format html and txt. will not be properly charged to the top, you will need to extract using the suite to generate .dmp

  This is how to extract the AWR data and

  sqlplus "/as sysdba"
  SQL> @$ORACLE_HOME/rdbms/admin/awrextr.sql
  

  and that's how to load upwards

  sqlplus "/as sysdba"
  SQL>@$ORACLE_HOME/rdbms/admin/awrload.sql
  

  Concerning

• in RAC STATSPACK report

  Hi master,
  
  We have therefore 2 node RAC on RHEL 4.7 (both) with the same set settings.
  
  I would like to know, if we need for setting these two node RAc report performance and database or statspack report of two RAC nodes will do?
  
  I have collected report to both nodes, but not database, because I think that the instances on the nodes represent the load on the database.
  
  Please correct if I am my bad...
  
  any suggestion is appreciated.
  
  
  Thanks and greetings
  VD

  Vikrant,

  You just need to run the /ADDM for the AWR report report of $ORACLE_HOME/rdbms/admin and it will be to collect information for both instances and therefore statspack.

  $> sqlplus '/as sysdba'
  sql> @$ORACLE_HOME/rdbms/admin/awrrpt.sql
  sql> @$ORACLE_HOME/rdbms/admin/addmrpt.sql
  

  Concerning

• In Oracle RAC STATSPACK report

  Dear friends,
  When I tried to do a STASPACK report on RAC nodes, I got the following error:
  Departure snap_id doesnot belong to this instance.
  
  When I tried to use the other node, I get the error:
  The fine snap_id doesnot belong to this instance.
  
  Is it something to do special cars waiting for the constraint of STATSPACK being of level 7 or more.
  
  
  
  Kind regards
  Aravind K R

  Snapshots are different for the different nodes. Please put the correct component ID software snap-in to collect the statpack report.

  After spending a lot of time fixing the formatting of the section of the AWR report posted, what follows is visible:
  Time (s) DB = 1.3 seconds per second wall clock
  Report total time = 645,084.25/1.3 = 496 219 seconds (approximately) = 137,84 hours

  Do not generate an AWR report with 137,84 hours. Why? First of all, allows you to hide the details important but who are lost in the medium - the numbers above show that your database instance has been almost (1.3 idle sessions occupied), these medium-sized sessions 1.3 spend 78.11% of their time waiting for events. Second, the substantive elapsed time is 86% of the time consumed by user sessions - who provided misleading information unless people recognise that the report covers everyday 5.74. Ideally, your AWR report should cover the minimum time necessary for analysis (and if you want to solve a problem with a single session, it is best to use a SQL extended 10046 trace). This amount of time can be 10 minutes, 15 minutes, 1 hour, or 3 hours, but (almost) never 5.74 days.

• Negative value to run to analyze the report in the statspack report

  Hello
  
  I use Oracle 10.2.0.3.
  
  In the Execute to analyze the value of its pack stats report report, I get the negative value-35%. I read that this means that there are more number of parse as executions. But how and where it can be checked off, and what step I can take to resolve/correct this?

  I have a procedure 'a' who calls the procedure b, c and d in it.

  I have a table "t" that is referenced in the proceedings b, c and d (not in one)

  I've run a DDL on the table "t" where, by b, c and d invalid and in which cases invalidate the procedure as well.

  I call the procedure 'a' for execution, but in this procedure, I circumvent enforcement of procedures b, c and d (I can do this based on a condition and I don't call these procedures during execution of the procedure a).

  Then, when I call the procedure, it will be recompiled, but before he could be recompiled, oracle has recompile b, c and d as well.

  So in this case, I don't have that a single execution of procedure 'a' but compilation of a, b, c and d have run to analyze the ratio of 1:4.

  I hope you understand now. Which is why I suspect me that your procedures are be invalidated yet and still have several compilations.

• Unable to find the id of the statspack report snapshot in Oracle 9.2.0.4

  Hello guys,.

  When I run @?/rdbms/admin/spreport.sql I am not able to see any id snapshot. I see all the values as #.

  Please find below the output, I get after I run @?/rdbms/admin/spreport.sql

• Need help for analysis "plan and background events waiting" on the report statspack for oracle database 11.2.0.4 on AIX

  HI: I analyze the STATSPACK report: this is the "volume test" on our UAT server for most of entry or "bind variables".  Our shared pool is well used in oracle.  Recovery of Oracle logs is not configured properly on this server, as in "Top 5 events of waiting", there are 2 for Oder.

  I need to know what other information may be digging from of 'waiting in the foreground events' & ' background waiting events ", and which can help us better understand, in combination of ' Top 5 wait event, that how did the server test /?  It could be overwhelming. wait events, so appreciate useful diagnostic or analyses.  Database is oracle 11.2.0.4 updated from 11.2.0.3 on IBM AIX 64-bit, level 6.x system power

  Thank you very much!

  Hello

  I think that your CPU is overloaded by your stress tests. You have one VCPU with 2 wires (2 LCPU), right? And the load average is greater than one. You have time DB which is not counted in (CPU time + wait events) and which comes no doubt from time spent in the runqueue.

  > Oracle recovery logs is not properly configured on this server, as in "Top 5 events of waiting", there are 2 for oder

  It is an error in statspack for show "log file parallel write here." This moment is historical and is included in 'log file sync '. And I don't think you have to redo misconfiguration. Waiting for 1ms to commit is ok. In OLTP you should have more than one validation in a user interaction so that the user don't worry not about 1 m in batch mode, unless you commit to each row, 1 DC to commit should not increase the total execution time.

  The fact that you have a lot of line lock (enq: TX - line lock conflict) but very little time (on average 97 ms) is probably a sign that testers are running simultaneously a charge affecting the same data. Their set of test data is perhaps too simple and short. An example: when stress tests of an order entry system if you run 1000 concurrent sessions, ordering the same product to the same customer, you can get this kind of symptoms, but the test we unrealistic.

  It's a high activity of 2000 calls per second, 52 transactions per second, user. But you also have low average active sessions, so the report probably covers a period of non-uniform activity, which makes the averages without meaning.

  So note to tell about the events of waiting here. But we don't have any info about 39% of DB time devoted to the CPU which is where something can be improved.

  Kind regards

  Franck.

• Run the report statspack remotely from a client?

  Hello!
  
  I run a statspack report @spreport.sql of SQL * Plus the term on the database server.
  
  Having to go on the DB server because it is sometimes a chore and I prefer to get a report of any customer, or even of in SQL Developer.
  
  Y at - it an easy way to achieve this or is it a tool for that?
  
  Obviously, the spreport.sql may be different from the Oracle DB version to another, and I would need to have a series of these reports on the client scripts and select the right one or I would need to have some mechanisum (stored proc?) coming to rdbms/admin on the server, so run the spreport.sql script, read the output and return from the customer.
  
  Y at - it an easier way or someone knows of a set that will do it?
  
  Thank you
  Marcus

  Marcus,

  I don't think that I don't have your question. Sorry, but don't you mean you want to get a report from the client terminal by running locally on the client only? That's what I got from this line,

  Having to go on the DB server because it is sometimes a chore and I prefer to get a report of any customer, or even of in SQL Developer.

  Or if you want the report is available on the server to the client's local computer?

  If you want the State you will be given on the client side only, I'm not sure that there is no possibly he. What is the problem in the reading of the report on the same server if? If you can connect to db valid db and the o/s user, it can recover the data as well. But it's just a thought. I do not use the tools a lot, so I guess, I'll just join you and see what others have to say about it.

  Aman...
