Order by takes more time
Hi,
My oracle version is 10.2.0.4.
I have a table with 5 million records.
When I query a table with
select * from table1;I get the results.
But when I do the same with
select * from table1 order by 1;the query takes unusally more time.
Even the select coun(1) from table1; doesn't return with the result and the session hangs.
Whereas I am able to do the same operation with a different table with 12mn records and it works fine.
Both indexes and user objects are in a single tablespace with 5 different datafiles.
Could you please guide.
I am not trying to insult your intelligence, but I recently had a user ask the question and it ended up being a very simple misunderstanding. Let me tell you what happened and it explain it and you can tell me if it is similiar or not.
The user launches SQL Developer and queries a table with 40 million records. A Select * returns results right away, a Select * with just about any simple where clause they could think of returned results right away but if they added the Order by statement or attempted to sort the result list by double-clicking the column it just hung for them.
I explained that SQL Developer by default only returns 50 records and stops (Toad does 500). So when they are not sorting the list the first 50 come in quickly and satisfy the query results. But when you perform an order by you must bring in the entire result set to then decide what is the first 50. Lets say you order by a Date, you must get everything in the system for your where clause, order that by date to then take the top 50.
While the user thought what they were doing was similiar there is in fact a night and day difference which they were seeing in the performance.

Automatic DOP take more time to execute query
We upgraded database to oracle 11gR2. While testing Automatic DOP feature with our existing query it takes more time than with parallel.

MRP job takes more time (Duration / Sec)
Hello PP Guru’s,
I have below situation in production environment,
MRP job for plant – A (Takes more time – 14.650)
MRP job for plant – B (Takes less time – 4.512)
When I compare the variant / attributes with plant A and B, I observe only difference in attribute is scheduling (2 - Lead Time Scheduling and Capacity Planning) for plant A.
For plant B scheduling (1- Determination of Basic Dates for Planned) it was updated.
So in my observation this scheduling is playing a major role for MRB job which takes more time in plant – A.
I am in process of changing the variant attribute for plant – A from scheduling 2 to scheduling 1.
I wanted to know from experts whether if I change any impact / problem will happen in future for plant A or not.
Please let me know what all the hidden impacts are there if I change the scheduling in variant attribute.
I look forward to your valuable input to reduce time for my MRP related job.
Regards,
Kumar SHi Kumar,
You have no need to change the inhouse production time you just need to update the Lot size dependent inhouse production time in work scheduling view of material master. That you can do by scheduling the routing/recipe.
Transactions CA97 or CA97N can be used to update the in-house production time with the information from the routing.
If business don't want to have the capacity planning for planned orders then you change the scheduling from 2 to 1 basic date scheduling.
Expert Caetano already answer you query
The reports listed below can be used to compare the MRP past executions regarding the runtime:
RMMDMONI: This report compares the runtime of the MRP execution and also provides the total of planning elements (planned orders, purchase requisitions, etc) changed, created or deleted. It also shows which planning parameters where used and how much time MRP spent on each step (database read, BOM explosion, MRP calculation, scheduling, BAdIs, etc). With this information is possible to observe the relation of runtime and number of elements changed/created/deleted and also to see on which step MRP is taking more time.
RMMDPERF: This report shows the "material hit list", that means, which materials had the highest runtime during the MRP execution and also on which step MRP is taking more time. Knowing which materials have the highest runtime, allow you to isolate the problem and reproduce it on MD03, where it is possible to run an ABAP or SQL trace for a more detailed analysis.

Optimizing the query - which takes more time
Hi,
Am having a query which was returning the results pretty fast one week back but now the same query takes more time to respond, nothing much changed in the table data, what could be the problem. Am using IN in the where clause, whether that could be an issue? if so what is the best method of rewriting the query.

i have followed this link http://www.lorentzcenter.nl/awcourse/oracle/server.920/a96533/sqltrace.htm in enabling the trace and found out the following trace output, can you explain the problem here and its remedial action pls.

Takes more time to start & shutdown the database
Hi All,
I have created a database in oracle9i by following manual steps. Every thing was created successfully and am able to start the database and shutdown also.
but the problem is while giving the startup command it takes more time to start the database and the same during the shutdown. So anyone help me..
the follwing are the pfile specifications:
db_name=practice
instance_name=practice
control_files= 'E:\practice\control\control1.ctl',
'D:\practice\control\control2.ctl'
db_block_size=2048

Thanks in AdvanceEvery thing was created successfully and am able to start the database and > shutdown also.Please restate the above.
problem is while giving the startup command it takes more time to start the >database and the same during the shutdownHow have you compared? Could it be O/S resources, installation of additional software; you have not mentioned the O/S and complete version of your database.
You can review the following although I am bit unclear;

PDF Form Takes More Time To Open when using designer 7.1.3129.1.296948
Hi All,
Adobe Reader Version : 8 and above.
designer : 7.1.3129.1.296948
When i am devloping the adobe interactive form Using designer 7.1.3129.1.296948, When I open the same in the adobe reader 8.1.2 and 9.1 its take more time (Nearly 20 mins).
When I am opening the same in the adobe reader 7.1 its opening fine.
How to resolve This problem in adobe reader 8.1.2,9.0 and 9.1 ?
Regards,
Boopathi MHi,
I have seen this exact same problem happening when, I created/developed a adobe form, on a PC which had adobe livecycle designer 7.1, but had adobe reader 7.
Once the form is created on a machine which had reader 7, then it does not matter whether u try to open that pdf in reader 8 or 9, it will take 20-30min to open, it will freeze your pc, etc.
Please ensure that when/where ever the form was first created, that machine had adobe reader 8 or higher installed it.
I hope this helps,

Please ensure that when/where ever the form was first created, that machine had adobe reader 8 or higher installed it.
I hope this helps,

'BAPI_GOODSMVT_CREATE' takes more time for creating material document
Hi Experts,
I m using 'BAPI_GOODSMVT_CREATE' in my custom report, it takes more time for creating Material documents.
Please let me know if there is any option to overcome this issue.
Thanks in advance

LeoHi,
please check if some of following OSS notes are not valid for your problem:
[Note 838036 - AFS: Performance issues during GR with ref. to PO|https://service.sap.com/sap/support/notes/838036]
[Note 391142 - Performance: Goods receipt for inbound delivery|https://service.sap.com/sap/support/notes/391142]
[Note 1414418 - Goods receipt for customer returns: Various corrections|https://service.sap.com/sap/support/notes/1414418]
The other idea is not to commit each call, but executing commit of packages e.g. after 1000 BAPI calls.
But otherwise, I am afraid you can not do a lot about performance of standard BAPI. Maybe there is some customer enhancement which is taking too long inside the BAPI, but this has to be analysed by you. To analyse performance, just execute your program via tr. SE30.

'BAPI_GOODSMVT_CREATE' takes more time for creating material document for the 1st time
Hi Experts,
I am doing goods movement using BAPI_GOODSMVT_CREATE in my custom code.
Then there is some functional configuration such that, material documents and TR and TO are getting created.
Now I need to get TO and TR numbers from LTAK table passing material documnt number and year, which I got from above used BAPI.
The problem I am facing is very strange.
Only for the 1st time, I am not finding TR and TO values in LTAK table. And subsequent runs I get entries in LTAK in there is a wait time of 5 seconds after bapi call.
I have found 'BAPI_GOODSMVT_CREATE' takes more time for creating material document with similar issue, but no solution or explanation.
Note 838036 says something similar, but it seems obsolete.
Kindly share your expertise and opinions.
Thanks,

Hi All,
I have cloned KSB1 tcode to custom one as required by business.
Below query takes more time than excepted.
Here V_DB_TABLE = COVP.
Values in Where clause are as follows
OBNJR in ( KSBB010000001224 BT KSBB012157221571)
GJAHR in blank
VERSN in '000'
WRTTP in '04' and '11'
all others are blank
VT_VAR_COND = ( CPUDT BETWEEN '20091201' and '20091208' )
SELECT (VT_FIELDS) INTO CORRESPONDING FIELDS OF GS_COVP_EXT
FROM (V_DB_TABLE)
WHERE LEDNR = '00'
AND OBJNR IN LR_OBJNR
AND GJAHR IN GR_GJAHR
AND VERSN IN GR_VERSN
AND WRTTP IN GR_WRTTP
AND KSTAR IN LR_KSTAR
AND PERIO IN GR_PERIO
AND BUDAT IN GR_BUDAT
AND PAROB IN GR_PAROB
AND (VT_VAR_COND).
Checked in table for this condition it has only 92 entries.
But when i execute program takes long time as 3 Hrs.
Could any one help me on this>1.Dont use SELECT/ENDSELECT instead use INTO TABLE addition .
> 2.Avoid using corresponding addition.create a type and reference it.
> If the select is going for dump beacause of storage limitations ,then use Cursors.
you got three large NOs .... all three recommendations are wrong!
The SE16 test is going in the right direction ... but what was filled. Nobody knows!!!!
Select options:
Did you ever try to trace the SE16? The generic statement has for every field an in-condition!
Without the information what was actually filled, nobody can say something there
are at least 2**n combinations possible!
Use ST05 for SE16 and check actual statement plus explain! -

How to stop the sap crm search in the middle if it takes more time
Hi,
We are in SAP CRM 7.0 EHP1.
In webui, if we search for any customer, product, contact, transactions and the volume of results list is more, system takes more time to diplay it in results list and till that time wheel spins. If user decides to stop the search, the only option they have is logoff or F5 which will take to new session.
But I came to know in EHP1, options are there to stop the search manually and proceed with other transactions/search in the same session.If any one knows this, pl share the details.
Regards
SureshHello,

Bind variable code takes more time to complete?
Hello, My database is oracle11g.
I have same plsql code and first one is without bind variable and second one is with bind variable. Usually, bind variable should take less time. But here
the bind variable takes more time than the regular code... Can any one please explain why?

Thanks for the clarification.. Now i understand...
One final question on this thread before i close this thread....
My database is set to CURSOR_SHARING=FORCE for some reason. It seems somebody applied a "quick and dirty fix" to "database is slow" problem. BAD PRACTICE
My question is, when we use bind variable, does it parse the sql code every time? or does it reuse the execution plan?
In my database, it reuse the execution plan... Just checking... When we set CURSOR_SHARING=FORCE, it should generate the execution plan
for every unqiue sql code... Is that correct? Am i confusing?If by "parse" you mean a "hard parse" (which generates execution plan), then the answer is NO. As you observed, it reuses execution plan.
For e.g. with CURSOR_SHARING=FORCE setting, following SQLs
select employee_no, first_name, last_name from employees where dept_no = 10 ;and
select employee_no, first_name, last_name from employees where dept_no = 20 ;would tend to reuse the same execution plan since both of these will be rewritten by oracle (before execution) as
select employee_no, first_name, last_name from employees where dept_no = :SYS01 ;Hope this helps.

DELETE FROM database table takes more time...
Hi Friends,
The below statement takes more time.
LOOP AT i_final.
DELETE FROM zcisconec WHERE werks = i_final-werks
AND aufnr = i_final-aufnr
AND vornr = i_final-vornr.
ENDLOOP.
Internal table I_FINAL will have more than 80,000 records.
DB Table zcisconec have 4 primary key fields out of 10 fields.
Below 4 fields are primary key fields
WERKS
AUFNR
VORNR
MATNR
Please guide me..How to optimize it?
Regards,
VijiHI,
Check this one ,
put a break point on that delete statement and add another line of code after, like .... CHECK SY-SUBRC = 0. Now got to debug and stop at the DELETE statement, check the number of records in your DB table, now hit F5 to step to the next statement, now go back to SE16 and refresh, do you see the number change? It should.........if you are selecting the data correctly, make sure that you are getting data into the IT_ table.
DELETE zcisconec from i_final.
CALL FUNCTION 'DB_COMMIT'.
Regards,
Ansari.
