Oracle mgw more time while fetching data from MQ
Dear All,
Good morning.
I am using oracle 11.2.0.3 version and using MGW to connect to MQ series (IBM WebSphere MQ ,Version: 7.5.0.0).
We are experincing delay while retriving message from MQ for some times and it is not happening always.

BAM reports taking more time while fetching data from EDS
I have created an external Data Source(EDS) in the BAM, and when i create an object with that EDS, it is taking very long to fetch data from the EDS( more than 20 mins.), but as the Database is installed on my local system, when i fire a query there, it don't take much time. Please help me in this, what could be the possible reason?

Hi,
we are using SQL SERVER 2008R2 X64 RTM version.
One of the SSRS report designed by developer is consuming much more time( 5 to 6 minutes ) to fetch data from DB. Even direct run of Stored Procedure (Called in report )takes less than a second to display the result set.
Please help.
Regards Naveen MSSQL DBAHi Naveen,
Based on my understanding, you spend a little time retrieving data with a stored procedure from database in dataset designer. However, it takes long time to run the report to display the data, right?
In Reporting Services, the total time to generate a report include TimeDataRetreval, TimeProcessing and TimeRendering. In your scenario, since you mentioned retrieving data costs a little time, you should check the table
Executionlog3 in the ReportServer database to find which section costs most of time, TimeProcessing or TimeRendering. Then you can refer to this article to optimize your report:
Troubleshooting Reports: Report Performance.
Besides, if parameters exist in the report, you should declare variables inside of the stored procedure and assign the incoming parameters to the variables. For more information, please refer to the similar thread:
Fast query runs slow in SSRS.
If you have any question, please feel free to ask.

I need to fetch data from an Archived table for all the entries in an internal table.
Kindly provide some inputs for the same.
thanks n Regards

I have a query regarding accessing archived data through PBS.
I have archived SAP FI data ( Object FI_DOCUMNT) using SAP standard process through TCODE : SARA.
Now please tell me can I acees this archived data through the PBS add on FM : '/PBS/SELECT_INTO_TABLE'.

How can we improve the performance while fetching data from RESB table.
Hi All,
Can any bosy suggest me the right way to improve the performance while fetching data from RESB table. Below is the select statement.
SELECT aufnr posnr roms1 roanz
INTO (itab-aufnr, itab-pposnr, itab-roms1, itab-roanz)
FROM resb
WHERE kdauf = p_vbeln
AND ablad = itab-sposnr+2.
Here I am using 'KDAUF' & 'ABLAD' in condition. Can we use secondary index for improving the performance in this case.
Regards,
HimanshuHi ,
Declare intenal table with only those four fields.
and try the beloe code....
SELECT aufnr posnr roms1 roanz
INTO table itab
FROM resb
WHERE kdauf = p_vbeln
AND ablad = itab-sposnr+2.
yes, you can also use secondary index for improving the performance in this case.

Eliminate duplicate while fetching data from source
Hi All,
CUSTOMER TRANSACTION
CUST_LOC CUT_ID TRANSACTION_DATE TRANSACTION_TYPE
100 12345 01-jan-2009 CREDIT
100 23456 15-jan-2000 CREDIT
100 12345 01-jan-2010 DEBIT
100 12345 01-jan-2000 DEBITNow as per my requirement, i need to fetch data from CISTOMER_TRANSACTION table for those customer which has transaction in last 10 years. In my above data, customer 12345 has transaction in last 10 years, whereas for customer 23456, does not have transaction in last 10 years so will eliminate it.
Now, CUSTOMER_TRANSACTION table has approximately 100 million records. So, we are fectching data in batches. Batching is divided into months. Total 120 months. Below is my query.
select *
FROM CUSTOMER_TRANSACTION CT left outer join
(select distinct CUST_LOC, CUT_ID FROM CUSTOMER_TRANSACTION WHERE TRANSACTION_DATE >= ADD_MONTHS(SYSDATE, -120) and TRANSACTION_DATE < ADD_MONTHS(SYSDATE, -119) CUST
on CT.CUST_LOC = CUST.CUST_LOC and CT.CUT_ID = CUST.CUT_IDThru shell script, months number will change. -120:-119, -119:-118 ....., -1:-0.
Now the problem is duplication of records.
while fetching data for jan-2009, it will get cust_id 12345 and will fetch all 3 records and load it into target.
while fetching data for jan-2010, it will get cust_id 12345 and will fetch all 3 records and load in into target.
So instead of having only 3 records, for customer 12345 it will be having 6 records. Can someone help me on how can i eliminate duplicate records from getting in.
As of now i have 2 ways in mind.
1. Fetch all records at once. Which is impossible as it will give space issue.
2. After each batch, run a procedure which will delete duplicate records based on cust_loc, cut_id and transaction_date. But again it will have performance problem.
I want to eliminate it while fetching data from source.
Edited by: ace_friends22 on Apr 6, 2011 10:16 AMYou can do it this way....
SELECT DISTINCT cust_doc,
cut_id
FROM customer_transaction
WHERE transaction_date >= ADD_MONTHS(SYSDATE, -120)
AND transaction_date < ADD_MONTHS(SYSDATE, -119)However please note that - if want to get the transaction in a month like what you said earlier jan-2009 and jan-2010 and so on... you might need to use TRUNC...
Your date comparison could be like this... In this example I am checking if the transaction date is in the month of jan-2009
AND transaction_date BETWEEN ADD_MONTHS(TRUNC(SYSDATE,'MONTH'), -27) AND LAST_DAY(ADD_MONTHS(TRUNC(SYSDATE,'MONTH'), -27)) Your modified SQL...
SELECT *
FROM customer_transaction
WHERE transaction_date BETWEEN ADD_MONTHS(TRUNC(SYSDATE,'MONTH'), -27) AND LAST_DAY(ADD_MONTHS(TRUNC(SYSDATE,'MONTH'), -27))Testing..
--Sample Data
CREATE TABLE customer_transaction (
cust_loc number,
cut_id number,
transaction_date date,
transaction_type varchar2(20)
INSERT INTO customer_transaction VALUES (100,12345,TO_DATE('01-JAN-2009','dd-MON-yyyy'),'CREDIT');
INSERT INTO customer_transaction VALUES (100,23456,TO_DATE('15-JAN-2000','dd-MON-yyyy'),'CREDIT');
INSERT INTO customer_transaction VALUES (100,12345,TO_DATE('01-JAN-2010','dd-MON-yyyy'),'DEBIT');
INSERT INTO customer_transaction VALUES (100,12345,TO_DATE('01-JAN-2000','dd-MON-yyyy'),'DEBIT');
--To have three records in the month of jan-2009
UPDATE customer_transaction
SET transaction_date = TO_DATE('02-JAN-2009','dd-MON-yyyy')
WHERE cut_id = 12345
AND transaction_date = TO_DATE('01-JAN-2010','dd-MON-yyyy');
UPDATE customer_transaction
SET transaction_date = TO_DATE('03-JAN-2009','dd-MON-yyyy')
WHERE cut_id = 12345

Sessions opening\closing in oracle while fetching data from XI
Hi Friends,
I used JDBC adaptor to fetch data from Oracle. I set the poll interval 86400 seconds because we need to run it on daily basis.
Now when XI fetch data from Oracle, It will open session in oracle, but it is not closed automatically. So, I have nearly 100 channels, and all channels are activated. So, for each channel 1 session is opened in oracle. By this way, the oracle server performance goes down. It is not working properly at that time.
How can I close these sessions in oracle.
Regards,
NarendraDid u try this paramter in JDBC sender adapter...
Disconnect from Database After Processing Each Message
Set this indicator if the database connection is to be released and reestablished before every poll interval.

Select query taking too much time to fetch data from pool table a005
Dear all,
I am using 2 pool table a005 and a006 in my program. I am using select query to fetch data from these table. i.e. example is mentioned below.
select * from a005 into table t_a005 for all entries in it_itab
where vkorg in s_vkorg
and matnr in s_matnr
and aplp in s_aplp
and kmunh = it_itab-kmunh.
here i can't create index also as tables are pool table...If there is any solutions , than please help me for same..
Thanks ,it would be helpful to know what other fields are in the internal table you are using for the FOR ALL ENTRIES.
In general, you should code the order of your fields in the select in the same order as they appear in the database. If you do not have the top key field, then the entire database is read. If it's large then it's going to take a lot of time. The more key fields from the beginning of the structure that you can supply at faster the retrieval.

Slow Speed While fetching data from SQL 2008 using DoQuery.
Hello,
I am working for an AddOn and tried to use DoQuery for fetching data from SQL 2008 in C#.
There are around 148 records which full fill this query condition but it takes much time to fetch the data.
I wanna know that is there any problem in this code by which my application is getting slower.
I used break Points and checked it, I founds that while connecting to the server it is taking time.
Code:
// Get an initialized SBObob object
oSBObob = (SAPbobsCOM.SBObob)oCompany.GetBusinessObject(SAPbobsCOM.BoObjectTypes.BoBridge);
//// Get an initialized Recordset object
oRecordset = (SAPbobsCOM.Recordset)oCompany.GetBusinessObject(SAPbobsCOM.BoObjectTypes.BoRecordset);
string sqlstring = "select DocEntry,ItemCode From OWOR where OWOR.Status='R' and DocEntry not in ( Select distinct(BaseRef) from IGE1 where IGE1.BaseRef = OWOR.DocEntry)";
oRecordset.DoQuery(sqlstring);
var ProductList = new BindingList<KeyValuePair<string, string>>();
ProductList.Add(new KeyValuePair<string, string>("", "---Please Select---"));
while (!(oRecordset.EoF))
ProductList.Add(new KeyValuePair<string, string>(oRecordset.Fields.Item(0).Value.ToString(), oRecordset.Fields.Item(0).Value.ToString() + " ( " + oRecordset.Fields.Item(1).Value.ToString() + " ) "));
oRecordset.MoveNext();
cmbProductionOrder.ValueMember = "Key";
cmbProductionOrder.DisplayMember = "Value";
Thanks and Regards,
Ravi SharmaHi Ravi,
your code and query look correct. But can you ellaborate a little bit.
It seems to be a DI API program ( no UI API ) ?
When you say "I founds that while connecting to the server it is taking time." do you mean the recordset query or the DI API connection to SBO ? The later would be "normal" since the connection can take up to 30 seconds.
To get data it is usually better to use direct SQL connections.

In the error it is showing that file expense_categories.csv in SOURCE_LOCATION not found but I am 100% sure that file is very much there.
Is anybody face the same issue?
Do we need to configure something before loading data from a flat file from OWB Client?
Any help would higly appreciable.
Regards,
Manmohan SharmaHi Detlef / Gowtham,
Now I am able to fetch data from flat files from OWB Server as well as OWB Client.
One way I have achieved as suggested by you
1) Creating location on the OWB Client
2) Samples the files at client
3) Created & Configured external table
4) Copy all flat files on OWB Server
5) Updated the location which I created at the client.
Other way
1) Creating location on the OWB Client
2) Samples the files at client
3) Created & Configured external table
4) Copied flat files on the sever in same drive & directory . like if my all flat files are on C:\data at OWB Client then I copied flat file C:\data on the OWB Server. But this is feasible for Non-Windows.
Hence my problem solved.
Thanks a lot.

Manmohan -
SELECT is taking lot of time to fetch data from cluster table BSET
<Modified the subject line>
Hi experts,
I want to fetch data of some fields from bset table but it is taking a lot of time as the table is cluster table.
Can you please suggest me any other process to fetch data from cluster table. I am using native sql to fetch data.
Regards,
SURYA
Edited by: Suhas Saha on Jun 29, 2011 1:51 PMHi Subhas,
As per your suggestion I am now using normal SQL statement to select data from BSET but it is still taking much time.
My SQL statement is :
SELECT BELNR
GJAHR
BUZEI
MWSKZ
HWBAS
KSCHL
KNUMH FROM BSET INTO CORRESPONDING FIELDS OF TABLE IT_BSET
FOR ALL ENTRIES IN IT_BKPF
WHERE BELNR = IT_BKPF-BELNR

Thanks in advance,
GauravHi Detlef / Gowtham,
Now I am able to fetch data from flat files from OWB Server as well as OWB Client.
One way I have achieved as suggested by you
1) Creating location on the OWB Client
2) Samples the files at client
3) Created & Configured external table
4) Copy all flat files on OWB Server
5) Updated the location which I created at the client.
Other way
1) Creating location on the OWB Client
2) Samples the files at client
3) Created & Configured external table
4) Copied flat files on the sever in same drive & directory . like if my all flat files are on C:\data at OWB Client then I copied flat file C:\data on the OWB Server. But this is feasible for Non-Windows.
Hence my problem solved.
Thanks a lot.

SSRS reports running slow while fetching data from SQL server DB
We are currently facing issues with lots of our SSRS reports running very slow. Approx they are taking around 15-20 minutes compared to earlier which was 2-3 minutes.
Also, the SSRS reports which fetch their data from a Database is acting as Subscriber for a reporting server. That is we have an OLTP DB server whose Database say 'A' is getting replicated onto the server where say Database 'B'. On this B we have our SSRS
reports fetching the required data and are reported to be running very slow.
As a start I have checked for Index and stats to be properly updated and yes they are.
I am not sure now, from where to start analysing the issue.
I believe replication, not to be the issue as earlier also we had replication set up and never saw the slowness.
IS memory or IO causing a problem, please help as i am not sure on how to find a fix for this?
Thanks in advance!Hi,
You need to first find out what all are slow? Is it that the whole instance is slow? How about other queries /replication etc against those databases? Are they slow?
Check the reports which are slow, try to find the slowest reports and then start looking at execution plans. Check if there is any kind of blocking happening during the time the reports run. Also try running the reports manually and see if there is a difference
in execution time. Take a look at the waitstats during the time the reports are running.
