Trying to cancel Discoverer query - it's taking along time to cancel ....
Hi Everyone,
I cancelled a query bec. it was taking a long time to run
Now it's taking a long time to cancel
The admin is out to lunch...
any advice pls, thx, sandra
Hi Sandra
Typically the reason for canceling a query is that it has been running too long - right?
Behind the scenes, one of two things is happening, either:
1. The query was having a hard time finding any data and is still searching, or
2. The query has found some data but not enough to satisfy the query governor settings
For the latter, depending upon how much data has so far been retrieved, Discoverer has to put that data somewhere. This is called a cache. The more data you put into a cache the more has to be cleared out of it should you decide not to proceed. This is probable what happened to you.
By the way, when you cancel a query you're generally asked a question about whether Discoverer should keep the last change but return no data. If you click Yes in reply to this question this is generally what triggers the clearing of the cache. Most of the time I just click No, even if I made a small change. I tend to get my query back quick.
Finally, if your Discoverer worksheet is a Crosstab or it uses Page Items, or even both at the same time, this is one of the causes of a long running query. In any of these scenarios, Discoverer has buckets to compute and it has no idea how many buckets to allow for until it has read all of the data.
In my Discoverer 10g Handbook and in my training courses I talk about The Query From The Twilight Zone. This are the queries that never or seems like never return any data and either time out or have to be stopped manually. Sometimes these runaway queries are trying to return every row of data from the database but more typically they are caused by the overcasual use of page items or Crosstabs.
Hope this synopsis helps
Best wishes
Michael

Query in timesten taking more time than query in oracle database
Hi,
Can anyone please explain me why query in timesten taking more time
than query in oracle database.
I am mentioning in detail what are my settings and what have I done
step by step.........
1.This is the table I created in Oracle datababase
(Oracle Database 10g Enterprise Edition Release 10.2.0.1.0)...
CREATE TABLE student (
id NUMBER(9) primary keY ,
first_name VARCHAR2(10),
last_name VARCHAR2(10)
2.THIS IS THE ANONYMOUS BLOCK I USE TO
POPULATE THE STUDENT TABLE(TOTAL 2599999 ROWS)...
declare
firstname varchar2(12);
lastname varchar2(12);
catt number(9);
begin
for cntr in 1..2599999 loop
firstname:=(cntr+8)||'f';
lastname:=(cntr+2)||'l';
if cntr like '%9999' then
dbms_output.put_line(cntr);
end if;
insert into student values(cntr,firstname, lastname);
end loop;
end;
3. MY DSN IS SET THE FOLLWING WAY..
DATA STORE PATH- G:\dipesh3repo\db
LOG DIRECTORY- G:\dipesh3repo\log
PERM DATA SIZE-1000
TEMP DATA SIZE-1000
MY TIMESTEN VERSION-
C:\Documents and Settings\dipesh>ttversion
TimesTen Release 7.0.3.0.0 (32 bit NT) (tt70_32:17000) 2007-09-19T16:04:16Z
Instance admin: dipesh
Instance home directory: G:\TimestTen\TT70_32
Daemon home directory: G:\TimestTen\TT70_32\srv\info
THEN I CONNECT TO THE TIMESTEN DATABASE
C:\Documents and Settings\dipesh> ttisql
command>connect "dsn=dipesh3;oraclepwd=tiger";
4. THEN I START THE AGENT
call ttCacheUidPwdSet('SCOTT','TIGER');
Command> CALL ttCacheStart();
5.THEN I CREATE THE READ ONLY CACHE GROUP AND LOAD IT
create readonly cache group rc_student autorefresh
interval 5 seconds from student
(id int not null primary key, first_name varchar2(10), last_name varchar2(10));
load cache group rc_student commit every 100 rows;
6.NOW I CAN ACCESS THE TABLES FROM TIMESTEN AND PERFORM THE QUERY
I SET THE TIMING..
command>TIMING 1;
consider this query now..
Command> select * from student where first_name='2155666f';
< 2155658, 2155666f, 2155660l >
1 row found.
Execution time (SQLExecute + Fetch Loop) = 0.668822 seconds.
another query-
Command> SELECT * FROM STUDENTS WHERE FIRST_NAME='2340009f';
2206: Table SCOTT.STUDENTS not found
Execution time (SQLPrepare) = 0.074964 seconds.
The command failed.
Command> SELECT * FROM STUDENT where first_name='2093434f';
< 2093426, 2093434f, 2093428l >
1 row found.
Execution time (SQLExecute + Fetch Loop) = 0.585897 seconds.
Command>
7.NOW I PERFORM THE SIMILAR QUERIES FROM SQLPLUS...
SQL> SELECT * FROM STUDENT WHERE FIRST_NAME='1498671f';
ID FIRST_NAME LAST_NAME
1498663 1498671f 1498665l
Elapsed: 00:00:00.15
Can anyone please explain me why query in timesten taking more time
that query in oracle database.

Taking Long Time To cancel any document on vl09
Hi,
In vl09 PGI/Delivery cancellation(when i cancel any document),Taking very long time.can i have to check any coding on program.guide me for the same.
ThankuYou can do an SQL trace via ST05 and analize to see what statements are taking that long... you can give this to your ABAPer to amend any faults on the coding or indexes.

Query in SAPKKA12 - taking long time
Hi,
The following query is from program SAPKKA12 and taking a long time to run . Any inputs how can I optimize it?
Will index creation on VBAP help?
SELECT vbeln
posnr
abgrs
objnr
werks
kzbws
fkrel
uepos
FROM vbap
INTO CORRESPONDING FIELDS OF TABLE posnr_tab
WHERE vbeln IN abgrvbel AND
posnr IN abgrposn AND
werks IN r_werks AND
prctr IN vp_prctr AND
kzvbr EQ 'E' AND
vbeln = vbap~vbelv AND
posnr = vbap~posnv AND
objnr <> space and
( (add_selection) AND abgrs IN abgrschl
OR (add_selection1) ).
Thanks in advance.
Neethu MohanRun an SQL trace on this select to find out where the time is burned. Since you are using VBELN and POSNR in the where condition the primary index should be used, but a where with a range is always slower than a where with a certain value.
Therefore an index would probably not help you here.
If the performance is really not acceptable you might want to raise an OSS to SAP regarding the issue.
Please post here in case they come back with a solution for this.
Hope that helps,

Rag: Query performence - Report taking long time when drill down a Char.
Hi All,
After executing the report when we try to Drilldown PO Char, then the report used to take long time nearly 60 to 90 minutes and thorough an errors that "An error is occurred during loading" or "Connection Timed Out".
The report is created on Multiprovider which is build on 7 infocubes and the data for the PO char is coming from all the 7 cubes.
So we have created Aggregates on the 5 Infocubes based on system proposal.
Then,
We checked in RSRT, the data is coming from all 5 Aggregates and also when we drill down the PO also the data is coming from 5 Aggregates itself.
But,
The report is running fine and also when we drilldown the PO to show all the PO values, then the report showing all the POu2019s details by taking nearly 15 mins only.
Here our concern is why the report is taking 15 mins when we drill a PO char.
Could any one give suggestions please.
Thanks in Adv.
Raju. EHi,

IOS5 taking along time to load - what now? it seems stuck.
I have loaded the itunes software, the IOS5 software, etc - now trying to restore the software for the iphone and it's stalled. It seems stuck at 15% - now what?
You have likely ruled out the possibility that the problem was with the iPad (by exchanging it). I would now suspect that the charger or cable is at fault. Take the charger & cable, along with the iPad back to the Apple Store and have them evaluate them all. If the charger and or cable is defective, they will exchange yours for another.

I tried to download a doctor who episode last night and it won't finish processing , how do I fix that ?
Okay, so istumbler says my connection goes to yellow when I go to the Aple TV location, but my internet speed is greatly increased tonight (20Mbps on speedtest.net near the router and 15.49Mbps at the Apple TV). Upload is unchanged at a little under 1Mbps). I did manage to get the Apple Contact location and I am sure they will post a credit for the movie (since their logs will show repeated attepts to download and no joy, although we both know they won't go to the trouble to look at them). As far as I'm concerned, it was a one-time problem and until it happens again to me, I will remain convinced it was on their end of the connection or in between (although that was unlikely). I've been administering and managing netowrks for over 20 years and am pretty confident that the connection on my end was working.

Taking much time when trying to Drill a characterstic in the BW Report.
Hi All,
When we are executing the BW report, it is taking nearly 1 to 2 mins then when we are trying to drill down a characterstic it is taking much time nearly 30 mins to 1 hour and througing an error message that,
"An error has occared during loading. Plese look in the upper frame for further information."
I have executed this query in RSRT and cheked the query properties,
this quey is bringing the data directly form Aggregates but some chares are not avalable in the Agrregtes.
So... after execution when we are trying to drill down the chars is taking much time for chars which are not avilable in the Aggregates. For other chars which are avilable in the Aggregates it is taking only 2 to 3 mins only.
How to do the drill down for the chars which are not avilable in the Aggregates with out taking much time and error.
Could you kindly give any solution for this.
Thanks & Regards,
Raju. EHi,
The only solution is to include all the char used in the report in the aggregates or this will the issue you will face.
just create a proposal for aggregates before creating any new aggregates as it will give you the idea which one is most used.
Also you should make sure that all the navigation characteristics are part of the aggregates.
Thanks

I dunno, it looks like you are getting all the things that are null with an outer join, so won't that decide to full scan anyways? Plus the union means it will do it twice and do a distinct to get rid of dups - see how it does a union all and then sort unique. Somehow I have the feeling there might be a more trick way to do what you want, so maybe you should state exactly what you want in English.
