Query takes long time - Please help!
I've a query like below (not actual query)
update (select eds.title eds_title,edv.title edv_title from mia_data_staging eds, mia_doc_Versions edv where eds.id = edv.id and eds.title != edv.title) set edv_title = eds_title;
In the above query I've more than 70 columns to select, compare and update (I've shown only one above). The explain plan for the query is below, which does not show any significant time, but the query never returns when executed after a long long time. Any ideas?

It also shows an unreasonable cost for that operation. The question is why it is not using a "full table scan" to access the MIA_DOC_VERSIONS table?
You might want to try simply the FULL hint to request a full table scan on the MIA_DOC_VERSIONS table in order to find out how the execution plan then is going to look like:
update (select /*+ FULL(EDV) */ eds.title eds_title,edv.title edv_title from mia_data_staging eds, mia_doc_Versions edv where eds.id = edv.id and eds.title != edv.title) set edv_title = eds_title;or
update /*+ FULL(a.EDV) */ (select eds.title eds_title,edv.title edv_title from mia_data_staging eds, mia_doc_Versions edv where eds.id = edv.id and eds.title != edv.title) a set edv_title = eds_title;Looking at the execution plan of the hinted statement one might get a clue why the optimizer favors an index access path instead.

Can't find a playlist I created on my playlist or computer? I didn't delete it. I don't want to create it again because it took a long time. please help me find and recover.
Playlists only exist as part of the larger iTunes library listing so if you are not seeing it there it doesn't exist anywhere else. I know with my older version of iTunes it is very easy to accidentally delete a playlist. With newer versions it may be possible to recover it with the undo feature in the menu but this likely will only work immediately after the deletion.

Hello experts,
My users have queries on a MultiProvider. Today, the queries take a long time to load. When they want to put a filter on it, the selection pop-up takes a long time to show the possible selections.
Is there any way to find out what causes the long wait time? And what can I do about it, to optimize it?
Thanks in advance.Hi Erica,
Please check load on system(how many users are logged in..?)
Please check : [Checklist for Query Performance|http://sapbwneelam.blogspot.com/2007/10/checklist-for-query-performance.html] some tips for query performance.
Hope it Helps

Query takes long time on multiprovider
Hi,
When i execute a query on the multiprovider, it takes very long time. it doesnt show up the results also. It just keep processing. I have executed the report only for one day but still it doesnt show any result. But when i execute on the cube, it executes quickly and shows the result.
Actually i added one more cube to the multiprovider and ten transported that multiprovider to QA and PRD. Transportation went on successfully. After this i am unalbe to execute the reports on that multiprovider. What might be the cause? your help is appreciated.
Thanks
AnnieHi Annie.......
Checklist for the performance of a Query........from a DOc........
1. If exclusions exist, make sure they exist in the global filter area. Try to remove exclusions by subtracting out inclusions.
2. Use Constant Selection to ignore filters in order to move more filters to the global filter area. (Use ABAPer to test and validate that this ensures better code)
3. Within structures, make sure the filter order exists with the highest level filter first.
4. Check code for all exit variables used in a report.
5. Move Time restrictions to a global filter whenever possible.
6. Within structures, use user exit variables to calculate things like QTD, YTD. This should generate better code than using overlapping restrictions to achieve the same thing. (Use ABAPer to test and validate that this ensures better code).
7. When queries are written on multiproviders, restrict to InfoProvider in global filter whenever possible. MultiProvider (MultiCube) queries require additional database table joins to read data compared to those queries against standard InfoCubes (InfoProviders), and you should therefore hardcode the infoprovider in the global filter whenever possible to eliminate this problem.
8. Move all global calculated and restricted key figures to local as to analyze any filters that can be removed and moved to the global definition in a query. Then you can change the calculated key figure and go back to utilizing the global calculated key figure if desired
9. If Alternative UOM solution is used, turn off query cache.
10. Set read mode of query based on static or dynamic. Reading data during navigation minimizes the impact on the R/3 database and application server resources because only data that the user requires will be retrieved. For queries involving large hierarchies with many nodes, it would be wise to select Read data during navigation and when expanding the hierarchy option to avoid reading data for the hierarchy nodes that are not expanded. Reserve the Read all data mode for special queriesu2014for instance, when a majority of the users need a given query to slice and dice against all dimensions, or when the data is needed for data mining. This mode places heavy demand on database and memory resources and might impact other SAP BW processes and tasks.
11. Turn off formatting and results rows to minimize Frontend time whenever possible.
12. Check for nested hierarchies. Always a bad idea.
13. If u201CDisplay as hierarchyu201D is being used, look for other options to remove it to increase performance.
14. Use Constant Selection instead of SUMCT and SUMGT within formulas.
15. Do review of order of restrictions in formulas. Do as many restrictions as you can before calculations. Try to avoid calculations before restrictions.
16. Check Sequential vs Parallel read on Multiproviders.
17. Turn off warning messages on queries.
18. Check to see if performance improves by removing text display (Use ABAPer to test and validate that this ensures better code).
19. Check to see where currency conversions are happening if they are used.
20. Check aggregation and exception aggregation on calculated key figures. Before aggregation is generally slower and should not be used unless explicitly needed.
21. Avoid Cell Editor use if at all possible.
22. Make sure queries are regenerated in production using RSRT after changes to statistics, consistency changes, or aggregates.
23. Within the free characteristics, filter on the least granular objects first and make sure those come first in the order.
24. Leverage characteristics or navigational attributes rather than hierarchies. Using a hierarchy requires reading temporary hierarchy tables and creates additional overhead compared to characteristics and navigational attributes. Therefore, characteristics or navigational attributes result in significantly better query performance than hierarchies, especially as the size of the hierarchy (e.g., the number of nodes and levels) and the complexity of the selection criteria increase.
25. If hierarchies are used, minimize the number of nodes to include in the query results. Including all nodes in the query results (even the ones that are not needed or blank) slows down the query processing. The u201Cnot assignedu201D nodes in the hierarchy should be filtered out, and you should use a variable to reduce the number of hierarchy nodes selected.

Hi All.
When i execute select query from View it takes about 00:00:45:12 sec to pull the data , but when i execute same query in some other system(different database with same table structure) it takes about 00:00:02:05 sec.
1)I have tried by dropped and recreated the index then i tried by exec dbms_stats.gather_table_stats procedure still no luck.
Please help me to understand the reason difference in response time
Thanks

Query takes long time to execute on exceptional cases
Hi Tuning Experts,
My query runs on prod db on daily basis on fixed scheduled time, out of seven days, for 1-2 exeptional days it takes 7-10 hr which takes 10-15 min on rest of the days.
I want to do RCA for it, so please help me how i can proceed. either i go with
AUTOTRACE,TKPROF, EXPLAIN PLAN or STATSPACK, which is best method to find out the real culprit.
Regards
AsifTo answer your question...
Running AUTOTRACE and EXPLAIN PLAN against the query in your development environment won't help diagnose the abnormal executions in production. Statspack is a global thing. It's a good thing to run but probably of insufficient granularity for here.
TKPROF is an anlyzing tool. You need something to analyze. Read this article on Interpreting Wait Events to find out how to set the 10046 event to gather evidence.

Ah, I just love these tuning questions. "My query is slow. Please make it go fast". Sure, put on these red shoes, click your heels three times and make a wish. Alas, tuning is rather more complicated than that, more of a science than a voodoo rirtual. We would like to help. But we need more data, some concrete figures. Otherwise we're just guessing.
So, first off, please read the Performance Tuning Guide. Apply some of its techniques. If you still don't understand why your query is running slow, come back to us with table descriptions, volumetrics, indexes, explain plans, stats, timings and tkprof output.
Good luck, APC -
Query takes long time to execute.
Hi All,
I have one query that takes 5 minutes to execute.
The query depends on four tables.

Select query takes long time....
Hi Experts,
I am using a select query in which inspection lot is in another table and order no. is in another table. this select query taking very long time, what is the problem in this query ? Pl. guide us.
select bPRUEFLOS bMBLNR bCPUDT aAUFNR amatnr aLGORT a~bwart
amenge aummat asgtxt axauto
into corresponding fields of table itab
*into table itab
from mseg as a inner join qamb as b
on amblnr = bmblnr
and azeile = bzeile
where b~PRUEFLOS in insp
and b~cpudt in date1
and b~typ = '3'
and a~bwart = '321'
and a~aufnr in aufnr1.
Yusufhi
instead of using 'move to corresponding of itab' fields use 'into table itab'.....
coz......if u use move to corresponding it will search for all the appropriate fields then it will place u r data........instead of that declare apprpiate internal table and use 'into table itab'.
and one more thing dont use joins ......coz joins will decrease u r performance .....so instead of that use 'for all entries' ....and mention all the key fields in where condition ........
ok

For a long time now, every time I've tried to log in to ebay (I can get into ebay, but I cannot log into my account, etc) or Paypal (I cannot even access this site), I get an error message stating that "the connection is untrusted" "You have asked Firefox to connect securely to signin.ebay.com, but we can't confirm that your connection is secure".- I've tried the standard solution i.e. resetting the time and date on my computer, but still this does not work.
Please help as this is severely restricting the use on my computer - and it's frustrating as hell!
Many thanksTry to rename the cert8.db file in the Firefox profile folder to cert8.db.old or delete the cert8.db file to remove intermediate certificates that Firefox has stored.
If that helped to solve the problem then you can remove the renamed cert8.db.old file.<br />
Otherwise you can rename (or copy) the cert8.db.old file to cert8.db to restore the previous intermediate certificates.<br />
Firefox will automatically store intermediate certificates when you visit websites that send such a certificate.
If that didn't help then remove or rename secmod.db (secmod.db.old) as well.
You can use this button to go to the Firefox profile folder:
