Hi,
can someone advice on what needs tunningFrom what you posted, CPU constitutes 40% of your wait times, yet without seeing the whole report it may be hard to find the root cause.
Sometime, high CPU can be caused by non-reentrant SQL in the library cache or sub-optimal SQL (excessive consistent gets), or any number of other root causes.
From what I see, it's NOT an I/O issue, since we don't see db_file_sequential_reads or db_file_scattered_reads, so it's not likely a data buffer shortage.
I would suggest running your SP report through http://www.statspackanalyzer.com or http://www.oraperf.com and report-back with the output.
Hope this helps. . . .

How to see values for bind variables in statspack output
Hi all.
Oracle9i Enterprise Edition Release 9.2.0.4.0 - 64bit Production
PL/SQL Release 9.2.0.4.0 - Production
CORE 9.2.0.3.0 Production
TNS for Solaris: Version 9.2.0.4.0 - Production
NLSRTL Version 9.2.0.4.0 - Production
Running sprepsql.sql to get full sql and explain plan from hash value...
SQL comes back with bind variables :1, :2, :3 etc.
How can I find out what the values are for the bind variables so i can plug them in and run them in test db?
Thanks for all your help.I don't have a trace file...
I need to know what the values are and if there is anyway to see them from the output of the sprepsql...
currently looks like:
select
r.status,
NVL(r.required_date, to_date('12/31/3999', 'MM/DD/YYYY')),
r.calc_qty,
r.issued_qty,
r.workorder_type,
r.workorder_base_id,
r.workorder_lot_id,
r.workorder_split_id,
r.workorder_sub_id,
r.operation_seq_no,
r.piece_no,
r.warehouse_id,
0,
wbs_code
from
REQUIREMENT r
where r.part_id = *:1*
and r.workorder_type = 'W'
and r.calc_qty > r.issued_qty
and r.subord_wo_sub_id is null
AND STATUS IN ('R', 'S','U','H','F')
AND WAREHOUSE_ID = *:2*
Thanks for your help. -
Sga_target_size and sga_max_size
I noticed our production Oracle Instance sga_target_size configuration might not utilize the host resource very well. The Solaris host has 32G physical memory, it is dedicated host for Oracle Instance, only one instance is running on there, but both SGA_TARGET_SIZE and SGA_MAX_SIZE are configured=2000M which is about 2G.
I want to increased the SGA_MAX_SIZE and SGA_TARGET_SIZE to 24G so that Oracle can better utilize the memory resource.
Any advice on this? Anything else I might neglect to check? Thanks in advance!Pl post details of OS and database versions.

Are there reasons you want to increase SGA ? Are you experiencing any performance issues ? If so, what do AWR / Statspack outputs show ?

Hello,
2 weeks ago our my boss told me to check the hardware of our Oracle 8.1.7 database. Cpu and memory looked fairly normal to me.
Now we have 10 disk in a raid10. Split up our oralog (F:), redolog (G:) and database (E:).
Created seperate disk for paging.
But this is what I get.
PhysicalDisk _Total 1 G: 3 F: E:

This is not even close to what I'm used to do...
Ps: have statspack logs and pslist logs...where do I need to look for!
Thank you in advance!
Cheers,
PJay,
Thank you for your reply. Can I run the sar command in windows?
I tought this was an Unix command.
Here is the statspack output.

9I STATSPACK PACKAGE를 이용하여 생성된 성능보고서 분석 예제
제품 : ORACLE SERVER

9I STATSPACK PACKAGE를 이용하여 생성된 성능보고서 분석 예제
==========================================
PURPOSE
이 문서는 9i 데이타베이스 운영 중 전반적인 System performance
저하를 경험할 경우 StatsPack Package를 이용하여 성능관련 문제
분석에 활용하는 방법을 예제를 통해 알아보기로 한다.
Explanation
<Bulletin:17118>에는 statspack.snap 프로시져를 수행하여 snapshot을
생성하는 데 있어 통계정보 수집 방법에 대하여 자세히 소개되어 있다.
<Bulletin:17119>에는 spreport.sql 수행을 통한 STATSPACK 성능 보고서
생성 방법과 생성되는 report의 내용을 요약적으로 볼 수 있다.
이 문서는 STATSPACK utility에 의해 생성되는 이 output(성능보고서)을
이해하고 진단하는 데 도움을 줄 만한 내용을 알아본다.
데이타베이스 performance tuning은 아주 광범위한 분야이므로,
아 자료는 몇 가지 특정 tuning point에 대해서만 촛점을 맞추어 알아본다.
1. 9i 에서 statspack 수행 시 Summary Information
STATSPACK report for
DB Name DB Id Instance Inst Num Release Cluster Host
ETSPRD7 1415901831 etsprd7a 1 9.2.0.5.0 YES tsonode1
Snap Id Snap Time Sessions Curs/Sess Comment
Begin Snap: 71 11-Jun-04 10:02:41 ####### .0
End Snap: 73 11-Jun-04 12:09:00 ####### .0
Elapsed: 126.32 (mins)
==> 이전의 OPS 항목은 Real Applications Cluster(RAC) 라고 하는 새로운
용어를 나타내기 위해 Cluster로 대체되었다.
그리고, Cursors/Session 과 Comment라고 하는 column이 추가되었다.
2. Oracle 9i Instance Workload Information
모든 statspack report는 instance efficiency를 결정하는 데 도움이 될
만한 인스턴스 metric들과 인스턴스의 workload profile을 보여주는 것으로
시작한다.
Oracle 9i에서 Std Block size는 인스턴스의 primary block size를 나타낸다.
1) Instance cache information:
Cache Sizes (end)
~~~~~~~~~~~~~~~~~
Buffer Cache: 704M Std Block Size: 8K
Shared Pool Size: 256M Log Buffer: 1,024K
2) Load profile Information:
Load profile Information은 Oracle 8i와 9i가 모두 동일하다.

% Blocks changed per Read: 19.12 Recursive Call %: 4.71
Rollback per transaction %: 2.24 Rows per Sort: 20.91
각 항목들의 의미는 다음과 같다.
Redo size: This is the amount of redo generated during this report.
Logical Reads: This is calculated as Consistent Gets + DB Block Gets = Logical Reads
Block changes: The number of blocks modified during the sample interval
Physical Reads: The number of requests for a block that caused a physical I/O.
Physical Writes: The number of physical writes issued.
User Calls: The number of queries generated
Parses: Total of all parses: both hard and soft
Hard Parses: Those parses requiring a completely new parse of the
SQL statement. These consume both latches and shared pool area.
Soft Parses: Not listed but derived by subtracting the hard parses
from parses. A soft parse reuses a previous hard parse
and hence consumes far fewer resources.
Sorts, Logons, Executes and Transactions are all self explanatory

Example
1. Parse가 너무 빈번하여 성능에 영향을 주는 예제
예제1. TARGET 이 100% 인데 다른 항목들은 좋은 편이지만, PARSE 관련
비율들만 낮은 경향을 보임.

shared free memory 125,065,548 107,550,900 14.00
너무 빈번한 Parse를 줄이기 위한 권장사항
- Literal SQL보다는 BIND VARIABLE 사용 권장
- SOFT PARSE가 85%나 차지하므로 Session_cached_cursors 파라미터 설정 권장
( 가령 100 --> 200 )
이 파라미터에 지정한 갯수는 한 session 동안 open된 상태로 cache에
유지할 수 있는 cursor의 갯수이다.
<참고> CURSOR 는 한번 오픈된 다음 여러번 execution 될 수 있다.
예를 들어 V$SQL 뷰에서 한 SQL 이 몇번 execute 되었는지는
v$sqlarea.executions 로 확인 가능하다.
<Note:30804.1> 참조
2. SQL ACCESS PATH(SQL 수행 패턴)와 I/O에 문제가 있어 성능에 영향을 주는 예제
SQL 수행 시 full table scan보다 INDEX scan이 항상 더 빠른 것은 아니다.
예제1. 전체 WAIT TIME 의 대부분(60~70%)이 DB FILE SEQUENTIAL READ,
즉 one block read (주로 인덱스 사용)일 때이다.

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:

Running statspack report remotely from a client?
Hi!
To get a statspack report I run @spreport.sql from an SQL*Plus session on the database server.
Having to go to the DB server for that sometimes is a chore and I would prefer to get a report from any client, or even from within SQL Developer.
Is there an easy way to achive this or is there a tool for that?
Obviously, the spreport.sql might differ from Oracle DB version to version, so I would either need to have a series of these reports scripts on the client and the select the right one or I would need to have some mechanisum (stored proc?) that gets to rdbms/admin on the server, executed the spreport.sql script there, read the output and return that from to the client.
Is there an easier way or anyone knows of a package that will do that?
Thanks,
MarcusMarcus,
I don't think that I did get your question. Sorry but do you mean to say that you want a report from the client terminal , running locally over teh client only? That's what I got from this line,
Having to go to the DB server for that sometimes is a chore and I would prefer to get a report from any client, or even from within SQL Developer. Or do you want the report to be available from the server side to the client's local machine?
If you want the report to be given to you on the client side only, I am not sure that there is any way possibly there. What's the issue in fetching the report from the server though ? If one can connect to db as a valid db and o/s user, he can fetch the data as well. But its just a thought. I don't use any of the tools much so I guess, I shall just join you and see what others have to say about it.

Execution time difference between Statspack and DBM_Monitor trace
Hi Everyone,
We noticed that output of query execution time is quite differ between statspack and session tracing (DBMS_MONITOR) report. The query execution time in Statspack was 1402 sec and in session trace file was 312.25 Sec. FYI database version is 11.2.0.3 which is installed on platform OL 5.8
Both of the following reports (Staspack/tracing) was executed on same system and at the same time. Could you suggest why execution time is differ in staspack and session tracing?
Staspack execution time :-
Elapsed Elap per CPU Old
Time (s) Executions Exec (s) %Total Time (s) Physical Reads Hash Value
1402.50 1 1402.50 9.1 53.92 256,142 3247794574

RajdeepHi,
First of all, please read the [url https://wikis.oracle.com/display/Forums/Forums+FAQ]FAQ page and find out how to use the code tags to format your output properly so that it's readable.
I don't want to work out the stats formatting but I'd guess that if you ran the query first time and the data was not cached, it would be slower than the 2nd query when it was cached. The stats should confirm this so please format them so we can see it properly.

The goal is to obtain the overall system statistics and explain plans for the entire system.
1. The only tool that I can think of is "StatsPack".
2. With AWR there are 2 issues:-
a. It is not free
b. It does not give Explain plan output.
3. We can use 10046 / 10053 Trace's however it wont give you as comphrehensive an output as statspack, you would also have to enable trace for each individual application while its running, grab the trace file, look at the report.
4. We can also use outlines to store the explain plan this was primarily for Oracle version 10g.
5. The last option we have is sql managed baselines. This is good , however it does not tell me conclusively how my system was executing a sql lets say 10 days back. It wont accept the new sql unless we promote it. Still there is no guarantee that the underlying sql plan will not change.
So far statspack with level 6 appears to be the only solution.Personally I'd spend the money and get AWR.
The problem with StatsPack is that when you run it, after an issue, it is too late to capture anything of value. With AWR snapshots are taken as often as you wish, 24 hours a day, and then when someone tells you there was a problem at 4:15 in the morning ... you have something to work with. -

Statspack ?? please correct if anything wrong
Dear all,
executed the spcreate.sql
log in as perfstat
SQL>variable jobno number;
SQL>variable instno number;
SQL>begin
select instance_number into :instno from v$instance;
dbms_job.submit(:jobno, 'statspack.snap;', trunc(sysdate+1/48,'HH'), 'trunc(SYSDATE+1/48,''HH'')', TRUE, :instno);
commit;
end;
To get the report :
spreport
begin snap_id 100
end_snap ID 112
file name : sp_100_112
Are the above steps correct. Where is the statspack file saved.
I see the output on the screen but cannot find the file.
Regards

Elapsed Time in Statspack report
There is a java process that made updates to 1 millon rows in the oracle database table. A commit was issued after each update statement in the code. There were 10 java threads(processes) involved in updating the 1 million rows and the total time took 3 hours and 40 minutes. However, in the statspack report pulled for that time period, it indicates that the total elapsed time was 4 hours and 3 minutes. What may be the cause for this difference ?
Thanks to all. I was also reading the same site. ALso what does these mean in case of session details.
memory sorts, table scans, physical reads, logical reads, cursors.
In some of the sessions I have these figures. What can I figure out from this.
(giving the output in vertical way)
ID 105
Status - INACTIVE
Machine- ebank_prd
User Name - EVENT
Elapsed Time- 16,237
CPU Used -645
Memory Sorts-25
Table Scans - 7866
Physical Reads -134
Logical Reads- 115249
Commits 7981
Cursor 104
Buffer Cache Hit Ratio 100
Another one :
26,INACTIVE,ebank_prd,CAIORA, 239,105, 31,093, 9,636, 67,032, 56,334 45,543, 860 0 8 100
Here the epalsed time is 239,105,
cpu used is 31,093
memory sorts is 9,636
table scans is 67,032
physical read 56,334
logical reads 45,543,860
The figures are so high
I performance is slow and what shall I do next to find out whats wrong by looking at the values.
Waiting for your answer.
Thanks again

Help interpreting v$rowcache_parent output

The number of items you have in the rowcache is quite large - are you making a lot of use of partitioned tables ?
It might be quite interesting to see the results of querying
select cache_name, count(*) from v$rowcache_parent group by cache_name;
select subcache_name, count(*) from v$rowcache_subordiate group by subcache_name;But the bottom line on this is that you should report ORA-00600 / ORA_0060N to Oracle support.
In this case I think they'll tell you that you need to have a larger shared pool (given the ORA-04031). But it's possible that they will suggest you set a hidden parameter to reduce the number of subpools to 1; or adjust the shared pool reserved to allow all this stuff to get into it and avoid fragmentation issues.
The release of 500MB is not a surprise - it's the type of thing that can happen just before the ORA-04031: Oracle kicks out a batch of objects to see if that will free up enough contiguous space to allow for your 4K allocation, then another batch - and so on until (a) it succeeds, or (b) it has to give up with a 4031. As this happens your application may stall for a few seconds as the shared pool goes through a massive latch storm (and it may stall again as a flood of "hard parsing" takes place to replace all the stuff that's been kicked out).
Does your application do a lot of truncating, or permanent or global temporary tables, or lots of create/exchange partition/drop - if you're using partitioned tables ? This can have a catastrophic effect on the shared pool in RAC. It shouldn't introduce a huge growth in the rowcache - but maybe you've found a related memory leak.

Hello All,
I am using Oracle 11g R2
I am new to the STATSPACK, and I have few questions:
Is it only a command line tool ? or it can be accessed through Oracle Enterprise Manager.
Can you provide me the details of how to generate reports? snapshots ? in STATSPACK

Regards,You dont need to take statspack reports anymore in 11gR2 use AWR instead. AWR has its advance functionality and includes almost everything to know whats running in instance.
Yes you can generate AWR report from OEM too.
from sql prompt you can run like
SQL>@?/rdbms/admin/awrrpt.sql
(specify begin snaphot time and end snapshot time)
you can have HTML or Text file as output.
And these will be created on you current OS path. hope this help.
