Statspack snap_level Query
Hi All,
I have started to use statspack to determine performance bottlenecks. However, when I generate a SPREPSQL report using the 'costly' sql hash value I do not see an Execution Plan. I have read the "Oracle Statspack Survival Guide" and see that I will have to change from snap_level 5 (default) to level 6.
http://www.akadia.com/services/ora_statspack_survival_guide.html
Level 5 This level includes capturing high resource usage SQL Statements, along with all data captured by lower levels.
Level 6 This level includes capturing SQL plan and SQL plan usage information for high resource usage SQL Statements, along with all data captured by lower levels.
My query is: Will changing the snap_level have any significant impact on performance?
Regards,
kp
My query is: Will changing the snap_level have any significant impact on performance?If it did it wouldn't be much use as a performance diagnostic tool. Of course it will have some impact but almost certainly too small to be measurable. Most machines should be running with sufficient spare cycles to handle the additional workload without anybody noticing. And if your system is one of the unhappy few, then the sooner you get enough data to fix it the better.
Personally, I think running at level=7 is the best idea.
Cheers, APC

Package.......StatsPack...Error..
Hi.. i m tuning my Oracle Database, for that i need to install Statspack package, when i compiled package... it returned following error.
Warning: Package Body created with compilation errors.
SQL> show error
Errors for PACKAGE BODY STATSPACK:
LINE/COL ERROR
2045/3 PLS-00201: identifier 'SYS.DBMS_SHARED_POOL' must be declared
2045/3 PL/SQL: Statement ignored
HOw to solve above error..Please check the following Package, and do help me.
Note: I m connected perfstat user, no as SYS user.
create or replace package body STATSPACK as

am i runnig the wrong query ?Hello,
You wrote:
SQL> select seg_cr_bks_rc_th from perfstat.stats$snapshot where rownum < 2;
select seg_cr_bks_rc_th from perfstat.stats$snapshot where rownum < 2
ERROR at line 1:
ORA-00904: "SEG_CR_BKS_RC_TH": invalid identifierAs you can check on the description of the Table perfstat.stats$snapshot, the column
SEG_CR_BKS_RC_TH doesn't exist in it.
So the error message is normal.
It seems that you don't have the right Table structure, you may recreate your statpacks
schema and check if it solves the issue.

Thanks for your help.
regards raitsarevoHi
I'm experienced any problem when our application run one transaction it becomes very slow, before it was speed and from yesterday it takes a lot of time to accomplish the transaction. That's why i analyze the problem with statspack and i've done also a trace. It's for my problem and for academic purpose too.
Many thanks for your help. -
Need suggestion on STATSPACK report
Problem:
Application running Very slow that too not consistent.
i am unable to find out where the problem persists.
I have given necessary details and attached Statspack report with this mail.
Need help very urgently...

End of ReportFrederic's right... you're summing up too many statspacks ..
Can't see anything specific apart from the fact that Statspack itself is showing up in the top statements.
First : define 'Slow' . What is your goal for 'Ok' ?
Start thinking about sql_trace, tkprof and 10046 traces -
Performance(statspack) related problem
Anybodyu can suggest me how to improve the database performance as many uiser are complaining that they are getting data very slow........
i have also used statspack analyzer.......

and on what basis you one should have to find out
which query causing the problem....
i also wanted to learn how to read the
statspack.........I personally do not like Statspack reports, but there are several very good sources for understanding Statspack reports:

Peformance of one process is slow ( statspack report is attached)
Hi,
My version is 9.2.0.7 (HP-UX Itanium)
we have recently migrated the DB from windows 2003 to Unix (HP-UX Itanium 11.23).
we have one process which usually takes 15 mins before migration, now it is taking 25 mins to complete. I did not change anything at db level. same init.ora parameters. tables and indexes statistiscs are upto to date.
Please guide me, what might be the wrong at instance level. Here I am skipping the sql query portion of statspack report due to security reasons.
this statspack report is taken before running the process and after completion of process.

Effect of RLS policy (VPD) on execution plan of a query
Hi
I have been working on tuning of few queries. A RLS policy is defined on most of the tables which appends an extra where condition (something like AREA_CODE=1). I am not able to understand the effect of this extra where clause on the execution plan of the query. In the execution plan there is no mention of the clause added by VPD. In 10046 trace it does show the policy function being executed but nothing after that.
Can someone shed some light on the issue that has VPD any effect on the execution plan of the query ? Also would it matter whether the column on which VPD is applied, was indexed or non-indexed ?

VPD is supposed to be invisible - which is why you get minimal information about security predicates in the standard trace file. However, if you reference a table with a security preidcate in your query, the table is effectively replaced by an inline view of the form: "select * from original_table where {security_predicate}", and the result is then optimised. So the effects of the security predicate is just the same as you writing the predicate into the query.
Apart from your use of v$sql_plan to show the change in plan and the new predicates, you can see the effects of the predicates by setting event 10730 with 10046. In current versions of Oracle this causes the substitute view being printed in the trace file.
Bear in mind that security predicates can be very complex - including subqueries - so the effect isn't just that of including the selectivity of "another simple predicate".
Can someone shed some light on the issue that has VPD any effect on the execution plan of the query ? Also would it matter whether the column on which VPD is applied, was indexed or non-indexed ?
Think of the effect of changing the SQL by hand - and how you would need to optimise the resultant query. Sometimes you do need to modify your indexing to help the security predicates, sometimes it won't make enough difference to matter.

ORA-1555 ORA-3136 errors:: elapsed time vs Query Duration
Dear all,
- My Database version is 11.2.0.2, Solaris.
- We have been having a problem in the production database where the front end nodes start going up and down for couple of hours sometimes. ; When node flapping is going on we get connection timed out alerts.
WARNING: inbound connection timed out (ORA-3136) opiodr aborting
process unknown ospid (4342) as a result of ORA-609 opiodr aborting
process unknown ospid (4532) as a result of ORA-609 opiodr aborting

Since this week node flapping is happening every day. Since past 2 days after or during node flapping we are getting ORA-1555 error.
Extract from alert log error:

Create statspack report using sql*developer
Hello,
While connecting with PERFSTAT user I can not create statspack report using SQL*Developer:
@?/rdbms/admin/awrrpt
Error starting at line 1 in command:
@?/rdbms/admin/awrrpt
Error report:
Unable to open file: "?/rdbms/admin/awrrpt.sql"
Actually, my problem or question is that how can PERFSTAT user can generate statspack reports from a Client side. What is the other way a non-dba can see the snapshots histroy and generate report (by using perfstat user ) while joing tables or using views?
Thanks a lot.
Best RegardsHi,
for awr reports @?/rdbms/admin/awrrpt (you need EE+Diagnostic Pack) there is a solution.
Grant execute dbms_workload_repository to <user>;
Grant select_catalog_role to <user>;
get all SNAP_IDs
SELECT TO_CHAR(s.startup_time,'YYYY.MM.DD HH24:MI:SS') INSTART_FMT,
di.instance_name INST_NAME,
di.db_name DB_NAME,
s.snap_id SNAP_ID,
TO_CHAR(s.end_interval_time,'YYYY.MM.DD HH24:MI:SS') SNAPDAT,
s.snap_level LVL
FROM dba_hist_snapshot s,
dba_hist_database_instance di
WHERE di.dbid = s.dbid
AND di.instance_number = s.instance_number
AND Di.Startup_Time = S.Startup_Time
ORDER BY snap_id desc;
Select * From Table(Sys.Dbms_Workload_Repository.Awr_Report_Html(DBID, 1, BEGIN_SNAP_ID, END_SNAP_ID));
For statspack i don't know a solutuion. I think the best idea is, create a job to make the statspack report on the server side and access it via external tables or mail them forward to you.
Best regards

The SQL statement is forcing the use of a specific index, is this the best index?:
SELECT /*+ INDEX (OM_COURSE_FEE OCF_CFC_CODE) */DISTINCT CF_COURSE_CODE FROM OM_COURSE_FEE,OT_STUDENT_FEE_COL_HEAD,OT_STUDENT_FEE_COL_DETL WHERE SFCH_SYS_ID = SFCD_SFCH_SYS_ID AND

NVL(STUD_REG_STATUS,0) != 23 AND STUD_COURSE_CODE != 'CCT' AND CF_COURSE_CODE= STUD_COURSE_CODE ) ORDER BY 1 DESC
Unfortunately, explain plans, even with dbms_xplan.display, may not show the actual execution plan - this is more of a problem when the SQL statement includes bind variables (capturing a 10046 trace at level 8 or 12 will help). With the information provided, it looks like the problem is with the number of logical reads performed: 17,503,305 in 84 executions = 208,373 logical reads per execution. Something is causing the SQL statement to execute inefficiently, possibly a join problem between tables, possibly the forced use of an index.
From one of my previous posts related to this same SQL statement:
SELECT /*+ INDEX (OM_COURSE_FEE OCF_CFC_CODE) */ DISTINCT
CF_COURSE_CODE

OM_COURSE_FEE,

There is the possibility of additional predicates being generated by Oracle which will make this possible without introducing a Cartesian join, but those predicates are not displayed with an explain plan (they will appear with a DBMS_XPLAN). I may not be remembering correctly, but if the optimizer goal is set to first rows, a Cartesian join might appear in a plan as a nested loops join - Jonathan will know for certain if that is the case.
Have you investigated the above as a possible cause? If you know that there is a problem with this one SQL statement, a 10046 trace at level 8 or 12 is much more helpful than a Statspack report.

Finding query access frequency or how many times a query has been executed?
Dear Experts
I need to find the total number of access frequency of individual queries that are requested by the users say at a particular time.
Say there are 20 distinct queries requested in the time difference of 3 hours. All of the 20 queries or some of the queries may be requested for more than 2/3 times at that time by other users. By the way say query Q1 is requested 5 times at that so its query access frequency or how many times this query is executed is 5.
From where and how can I can find this counting of query access frequency or how many times a query has been executed at particular time or a session?
Normally we know the there SQL history dynamic performance views or if it can be possible to query the Shared pool library cache for SQL area it may be possible to find the total number of execution time for a query. But how to find that if anyone knows, please help me about this.
Regards-
Engr. A.N.M. Bazlur Rashid
OCP DBAThat's one of the stats reported by statspack - assuming that your query does sufficient work to meet the thresholds for the standard report. Executions is of course one of the columns of v$sql so you might just wish to sample that yourself. Finally if you are on 11g and the sql you are interested is relatively low resource intensive and you are licensed for AWR then you can use the slightly madly named "colored sql" feature that ensures that a specific statement will always be sampled for AWR.

Response Time of a query in 2 different enviroment
Hi guys Luca speaking, sorry for the bad written english
the questions is:
The same query on the same table, for definition, number of rows, defined on the same kind of tablespace, the tables are analized
*) I have a query in Benchmark with good results in execution time, the execution plan is really good
*) in Production the execution plan is not so good, the response time isn't comparable (hours vs seconds)
#### The Execution Plan are different ####
#### The stats are the same ####
this a table storico.FLUSSO_ASTCM_INC A with this stats in benchmark
chk Owner Name Partition Subpartition Tablespace NumRows Blocks EmptyBlocks AvgSpace ChainCnt AvgRowLen AvgSpaceFLBlocks NumFLBlocks UserStats GlobalStats LastAnalyzed SampleSize Monitoring Status

in Production the stas are the same
the other one is an external_table
the only differences that I noticed at the moment is about the tablespace used to defined the table on:
Production

I'm studing on at the moment
What I have to check to obtain the same execution plan (without change the query)

Thanks a lot LucaHi Luca,
test and production system are nearly identicall (same OS, same HW Plattform, same software version, same release)
you're using external tables. Are the speed of these drives are identically?
have you analyzed the schema with the same statement? Could you send me the statement?
have you system statistics?
have you testet the statement in an environment which is nearly like the production? concurrent user etc.
Could you send me the top 5 wait events from the statspack report.
Are the data from production and test identical? No data changed. No Index drop? No additional Index? All tables and indexes are analyzed
Regards
Marc
