SQL to BI Scenario

Hi All
I have 9 scenarios.
XI is picking a data from SQL and sending to BI system.
Sender commuication channels poll interval = 7200 for all 9 channels.
Problem is: whenever i activate the channels my SQL server gets down and when i deactivate the XI channels sql starts working properly.
What could be the problem please let me know what can be done.
Receiver side I am using RFC.
Regards
Dheeraj Kumar

Hi Dheeraj,
Refer the note Note 831162 - FAQ: XI 3.0 / PI 7.0 / PI 7.1 JDBC Adapter point 14
JDBC Sender: Performance Issues After Configuring A Large Amount Of     Channels
    * Q: After configuring a large amount of JDBC Adapter sender channels, the J2EE Engine becomes very slow and some services start to block. How can I solve this issue?
    * A: Up to and including XI 3.0 SP13 each JDBC Adapter sender channel permanently consumes a J2EE application thread. To solve this issue, increase the number of configured J2EE application threads using the SAP J2EE Engine Config Tool ("cluster-data" -> "Global server configuration" -> "managers" -> "ApplicationThreadManager" -> "MaxThreadCount").
      Starting with XI 3.0 SP14 application threads are allocated on demand by the JDBC Adapter and returned to the thread pool after it has finished the polling sequence, so thread shortage situations will typically occur much more rarely than with earlier SPs.
Try to increase the number of J2EE application threads

SQL to XI Scenario (message delivery problem)

Hi All
Scenario is:
Sender Communication Channel is polling data from SQL.
From SQL around 2,75,000 records need to be picked up.
Communication Channel has successfully picked up data.
When i see communication channel monitoring getting an error
"Transmitting the message to endpoint http://hkbxiprd:8000/sap/xi/engine?type=entry using connection JDBC_http://sap.com/xi/XI/System failed, due to: com.sap.aii.af.ra.ms.api.RecoverableException: java.io.IOException: Error writing to server."
What is this error and how to sove it.
As XI sender channel already picked up data so flag in SQL side is also updated so cant try to pick up data again from SQL. All the records got stuck in adapter engine.
I also tried to resend the message but still getting the same Error Message.
Please suggest what can be done.
Regards

Hi Priya,
Take the input payload from Moni and test your message mapping (using test tab). Keep the Trace to All and see which target element is not getting created.
Is your mapping like this?
Source Data Type is EMPLOYEE_MST_Data_Type
I-row --->I-Item
I-Field1 --> I-Field1
I-Field2 --> I-Field2
I-Field3 --> I-Field3
I-Field4 --> I-Field1

Security question: Can you decompile a PL/SQL compiled procedure?

I am wondering if anyone would be able to tell me if it is possible to decompile a compiled oracle PL/SQL procedure.
Scenario:
I create some data encryption code in PL/SQL that contains an encryption key string. I compile the PL/SQL as a stored procedure and store that binary object as a BLOB in the database. If a hacker can snag a whole database that would include this BLOB and he figures out that the BLOB might contain the key, can he get access to the key by decompiling somehow the BLOB back into PL/SQL statements?
Thanks in advance!!
Gary Glover, CISSP
[email protected]

Gary, when a hacker gets into your database (with sysdba rights), your are pretty much screwed - even with encrypted code and data.
To obtain that level of access, the hacker must be good. And persistant. Thus you can expect that he will compromise the rest of the stuff inside the database.
Alternatively, your database security was shoddy - trying to patch security via encrypting code in the database is a poor second.
It is also a question of time and effort vs. benefits. Spend 80% attempting to secure the code in the database, and 20% securing the database? Or 90% securing the database and 10% securing the code and data in the database?

Linking two tables in SQL

Hi,
Iam struggling with SQL for this scenario..can you please through some light on this.
Table A:
Order Number || W.O.Number || Enetrprise || ResourcePool
1 || 1 || A || RP1
2 || 2 || A || RP1
3 || 3 || A || RP2
4 || 4 || A || RP2
5 || 5 || A || RP3
B
ResourcePool || Available Date
RP1 || 20-Dec-2007
RP1 || 21-Dec-2007
RP1 || 22-Dec-2007
RP2 || 20-Dec-2007
RP2 || 21-Dec-2007
RP3 || 20-Dec-2007
RP3 || 21-Dec-2007
My query should fetch
Order Number|| W.O.Number|| Enetrprise|| ResourcePool|| Available Date
1 || 1 || A || RP1 || 20-Dec-2007
1 || 1 || A || RP1 || 21-Dec-2007
1 || 1 || A || RP1 || 22-Dec-2007
2 || 2 || A || RP1 || 20-Dec-2007
2 || 2 || A || RP1 || 21-Dec-2007
2 || 2 || A || RP1 || 22-Dec-2007
3 || 3 || A || RP2 || 20-Dec-2007
3 || 3 || A || RP2 || 21-Dec-2007
4 || 4 || A || RP2 || 20-Dec-2007
4 || 4 || A || RP2 || 21-Dec-2007
5 || 5 || A || RP2 || 20-Dec-2007
5 || 5 || A || RP2 || 21-Dec-2007
when Iam including A.resourcepool=B.resourcepool in the query its returning no rows.
Thanks

(repeated)
select Order Number,W.O.Number, Enetrprise, a.ResourcePool, Available Date
from a,b
where a.resourcepool=b.resourcepool;
this is the simplest join condition.
just check whether you have some data in those tables!

XML parsing with SQL/PL-SQL

Hi,
My question is about how can an XML message can be best parsed using SQL/PL-SQL.
The scenario is as follow. The XML message is stored in a CLOB; only some of its data needs to be extracted; there are six different types of structures of XML; the size of each XML is about 50 lines (maximum depth level is 3); the data could be written in English or Greek or French or German or Russian; this is going to be done every hour and the parsing is going to be against 3,000 records approx.
In the development, I need to take into consideration performance. We are using Oracle 10, but we could migrate to Oracle 11 if necessary.
Apologies for this basic question but I have never done XML parsing in SQL/PL-SQL before.
Thank you.
PS I have copied this question to the XML forum.

Sql Server agent Jobs running

Hi All,
We have a scenario where we have to run 30 pkgs at same second. Each pkg is designed to fetch 60 lakh per day records and load it into Oracle/OLEDB destination.
For which we have created 30 SQL agent jobs for each pkg running every 5 mins 24/7. We want to test running with option(1) these 30 jobs on single sql server instance and option(2) 10 jobs each on 3 sql server instances. Can someone please help me out to understand
which would give me the better results.
a) The main advantage of multiple sql server instance scenario when compared with single sql server instance?
b) How much does the hardware configurations impact on the performance?
Thanks in Advance....

1. Exposed to race conditions means ?
2. What you mean distributing computing? Can't the SQL Server handle this much load ?
3. Yes, 60 lakh records per day.
4. Multiple Instances on the same machine. The jobs might scale up to 300 jobs.
So, please suggest whether multiple instances would help the approach in scaling up ? Or the Single instance can handle all the 300 jobs at same second?
Please advice which approach would be best and why?
Re #1: means it will step on each other
#2: is when you take a chunk of data and process each separately at the same time. SQL Server or not will use the resources available on the machine. And they are not elastic.
#3: So thanks @Vaibhav it is 600K records to process so per 5 min it is 300 records which not too many for even one SSIS package on a commodity server. Question though is how long is the record. And what needs to be done to "process", if it takes
longer than 5 min - boom you are trouble with your approach (#1 happens)
Lastly, how do you know it will scale?
To answer you need
1) Provide with technical specs of your prod machine
2) Do a proof of concept
3) Profile a load to see where improvements can be done because in ETL it is common to get more and more data as the time goes by. I also fail to understand how the concurrently running packages will understand what data not to process because another package
grabbed it.

Is it possible to write an abap code be SAP SQL query.(ECC 6)

hello guys,
Is it possible to write an abap code be SAP SQL query.
Scenario : table A has a field say f1 of length 10 and table B has a field say s1 of lenght 20. in sap sql i am able to link all the other tables but i am not able to link
table Af1 --->Table Bs1. as the length doesnot match. so is it possibel that using abap code I can pick 10 characters from table A field f1 adjust it to 20 characters using abap and map it to field s1 of table B.
Please let me know how to accomplish this if possible.
thanks in advance!!

Herm,
Adding code is done in the infoset.
Please do following:
> Goto SQ02
> Type in the infoset that the basis for your query, <change>
> Press <code> OR <shift><f8>
> Tou'll see 4 tabs: Extras, Selections, Code, Enhancements.
> GoTo tab Code
> Choose the coding section (<f4> gives you an overview)
> Enter the code.
You may set a breakpoint to see what the query in SQ01 will do with it.
Succes!

Creating Multiple INSERT statements with SQL

is there a way to create multiple INSERT staements with SQL .
Example scenario : This is only example but i have lot of data in the real time.
sql : Select Emplid from Table A where Emplid between 100 and 350 will retun me 50 rows . i want to insert those rows into another table.
I am looking for output like below instead of Giving output just as EMPLIDs
Insert into PS_LM_DATA ( EMPLID ) values ( 123 )
Insert into PS_LM_DATA ( EMPLID ) values ( 234 )
Insert into PS_LM_DATA ( EMPLID ) values ( 334 )
and so on....
thanks ,
Karu

If you are inserting into another table, you could use
insert into PS_LM_DATA ( EMPLID )
select Emplid from Table A where Emplid between 100 and 350Example:
SQL> insert into emp2(empno) select empno from emp;
14 rows created.
SQL> insert into emp2(empno) select empno from emp where empno between 7369 and 7788;
8 rows created.

SQL Query based on prority

All,
I've 3 task - A,B and C,each task have different prority
Task A has higer priority and then task B and then Task C.
Scenario#1:
clientid      - tname      - sdate      - edate
100      - A      - 20 Jan 11     - 22 Jan 11
100      - B      - 22 Jan 11     - null
in this task A has higer priority then task B ,so outcome should be:
100 - A - 20 Jan 11 - null
Scenario#2:
clientid      - tname      - sdate      - edate
200      - A      - 25 Jan 11     - 25 Jan 11
200      - B      - 25 Jan 11     - 25 Jan 11
200      - C      - 25 Jan 11     - null
in this scenario all task start and end on same day,so final outcome should be:
200      - A      - 25 Jan 11     - 25 Jan 11
200      - B      - 25 Jan 11     - 25 Jan 11
200      - C      - 25 Jan 11     - null
Scenario#3:
clientid      - tname      - sdate           - edate
400      - C      - 1 Mar 11     - 6 Mar 11
400      - B      - 6 Mar 11     - null
in this scenario task B has higer priority then task C ,so outcome should be:
400      - B      - 6 Mar 11     - null
SQL for all scenario: Pls help to do it through sql or any procedure or function.
WITH task_dtl AS
(SELECT 100 client_id, 'A' tname ,to_date('20/1/2011','DD/MM/YYYY') stdate,to_date('22/1/2011','DD/MM/YYYY') edate FROM DUAL UNION ALL

Thanks,

Please learn to post your data and code using {noformat}{noformat} tags as per the FAQ: {message:id=9360002}
As for your question, I'm not sure I understand the logic behind these 'priorities'.
scenario 1 appears to be... if the sdates' are different then take the tname and sdate from the higher priority A, and the null edate regardless of priority.
scenario 2 appears to be... if the sdates = the edate then ignore priorities, including where the edate is null?
scenario 3 appears to be... if the sdates' are different then take the tname and sdate from the higher priority A, and the null edate (similar to scenario 1)
Where is the consistency in the logic?

Is there a way to Insert Data into a Lookup Column Type on a SharePoint List Destination in SSIS?

Greetings.
I have successfully worked out inserting SQL data (2008 R2) into my 2010 SharePoint list (New, Update, Delete) by creating an SSIS Data Flow Task as outlined here:
http://fsugeiger.blogspot.com/2010/01/synchronise-sql-table-with-sharepoint.html
However, the problem I am running into is inserting data into the SharePoint Columns that are "Lookup" column types. I verified that all of the values I am copying from SQL into the SharePoint lookup column exist in the customn list it is pointing to. It
is important to have this column be a lookup column as it links to another custom list that has many more columns of related information.
I have read and re-read the SharePoint SSIS Adapters 2011.docx from
http://sqlsrvintegrationsrv.codeplex.com/ and the only section that seems to apply is this:
"Looking Up Values in a SharePoint List
If you have to look up a value in a SharePoint list, you can use the Lookup transformation in your data flow, and use the SharePoint List source to load the lookup table. You may have to add a Derived Column transformation or a Script component that splits
data in the lookup column on the ";#" delimiter to separate the ID value from the description.
If you are replacing values in your data with the values that you look up in the list, then loading the changed data back into SharePoint, you only have to include the ID from the lookup column. SharePoint ignores the description if you include it."
I am not sure if the above statement means that I should be passing the assocaited ID's other than the actual data into the SharePoint List destination. If that is the case, that will not really work as the lookup contains hundreds of rows. Not too mention
I have several of these lookup column types pointing to several different lists.
Any guidance in how I can put data into a SharePoint Lookup column type via Data Flow Task would be so much appreaciated.
Thank you.
My errors are:
Error: 0x0 at Data Flow Task, SharePoint List Destination: Error on row ID="1": 0x1 - Unspecified error, such as too many items being updated at once (batch), or an invalid core field value.
Error: 0xC0047062 at Data Flow Task, SharePoint List Destination [1903]: Microsoft.Samples.SqlServer.SSIS.SharePointListAdapters.PipelineProcessException: Errors detected in this component - see SSIS Errors at Microsoft.Samples.SqlServer.SSIS.SharePointListAdapters.SharePointListDestination.ProcessInput(Int32

component returned an error from the ProcessInput method. The error is specific to the component, but the error is fatal and will

I have found a solution to my problem and thought I would share it here in case there are others who are struggling with the above scenario. If you have a better way, I would love to hear about it since my way is a bit tedious.
In a nutshell, in order to have an SSIS package put data from an OLE DB Source into a SharePoint List Destination Lookup Column, you need to pass the ID of the value that is being looked up, not the value that is in the “master” OLE DB source.
Rough explanation, OLE DB Source value for column “Approp” is “4005” --> SQL matches “4005” with the ID in the new lookup table (“4005” = ID “5” as defined in the SharePoint lookup list) --> “5” gets passed into SharePoint List destination lookup
column --> SharePoint displays “4005” and successfully links to the lookup list.
Funny thing (not really), the error(s) outlined in my original post are not related in getting data into a SharePoint Lookup column as I am now successful in getting data into the system but I am still getting the same above error(s). I think it has to do
with the ID column in the SharePoint list destination. What I can’t seem to figure out is why since I am not linking any data to that ID column (at least on new records). I am however linking it on Update and Delete and the errors mentioned above disappear
and things work well.
There are three tasks that need to get done in order to get data from SQL into a SharePoint lookup column assuming you have already set up your SharePoint lookup lists:
1. Create new lookup table(s) in SQL that has the IDs from the SharePoint Lookup list and the values coming from the “master” OLD DB Source. You can see the ID column in SharePoint by toggling it on in a view.
2. Create a SQL command that JOINs all the databases and tables so that the ID is passed and not the value into the SharePoint lookup column
3. Change the “Data access mode” to “SQL Command” instead of the “Table or view” in the OLE DB Source and paste your command into the “SQL command text:” area.
Other helpful info is that you may also need to add additional columns in the new lookup tables in SQL for the scenarios when the data is not unique. You can see this two times in my SQL command example for Units and JobTitles:
SELECT
pps.SSNm,
pps.file_updated,
pps.Employee_id,
/* pps.CheckDistNm,*/
Check_Distribution_id = COALESCE( d.ID, 0 ),
pps.Job_nbr,
pps.SeqNm,
pps.action_eff_dt,
Fund_id = COALESCE( f.id, 0 ),
Appropriation_id = COALESCE( ap.id, 0 ),
ActionCode_id = COALESCE( ac.id, 0 ),
SpecNumber_id = COALESCE( jt.ID, 0 ),
pps.Employee_id,
/* pps.Fund,
pps.Approp,
pps.Unit,*/
Unit_id = COALESCE( u.ID, 0 ),
PosNm,
PosCode,
pps.LastName,
pps.FirstName,
pps.MI

x_PPS.aReportVw.pps_screens_active AS pps

Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.
3)When I copy excel file from dev to prod server and Give prod server path ,then SSIS package execute Successfully
NOTE :
a)ACE.OLEDB 64 bit (2010 )driver is installed on prod server
b)Same SP execute successful in Prod SSMS
c) SSIS and SP execute successful in Dev server
I have even Share development server Folder with everyOne so that File in it is accessible
Also given Read Write permission to excel file and folder
WHY my SSIS package with SP FAIL when Picking file from dev server ??? where as same SP runs fine on SSMS
HOW to resolve this.... ?? Please assist

You just gave more valuable info...
exec [dbo].[spLoadexcelEMPdata] runs locally on the prod machine
Thing is, you have the 64 bit driver, so it might work from the package or SSDT/VS if you set them to 64 Bit mode
It is because the complete office is not necessary for OpenRowset.
I assume, you referenced the driver
OPENROWSET('Microsoft.ACE.OLEDB.12.0', 'Excel xyz.0;...

Oracle Performance tunning genral question

Hi,
Below is the list of Areas of Oracle db for which tunning activities are done. You are invited to comment to it weather this is complete list or need some addition or deletion. As I'm learning PT for Oracle now a days, therefore I want to expand my knowledge by sharing what I'm learning and what I need to learn.
So comment with Open hearts on it. Espically from experts and Gurus.
Here is the List
1-Planning for Performance, include Storage consideration( Weather it is SAN, NAS, DAS), Network planning and host OS planning with proper configuration for running Oracle.
2-Database desining (Not under-Normalized and not Over-Normalized with proper usage of Indexes, views and Stored Procedures)
3- Instance tunning (Memory structure + B.g Processes)
4- Session tunning.
5- Segment Space tunning.
6- SQL tunning.
This is what uptill what I've learned. If it needs addition kindly tell me what are these. Please also provide me links(good and precise one) for PT tutorials on web.Also note that I'm discussing this w.r.t Single instance non-rac db.
Looking for Good sugessions
Regards,
Abbasi

How to integrate BW /BI using XI as middleware ?

Hi All
        How to integrate SAP BW/BI using XI to RDBMS(Oracle/SQL) ?
        Our scenario's includes 4 systems in the landscape
        Legacy, RDBMS, R/3 and BW
        RDBMS to BW ?   is it the same as R/3 or any difference ?
        we are not much aware about BW
can any one help on this part
regards
---kiran LVS

Hi
    Integration is almost same as SAP R/3 with few changes
    follow the link which will give clear idea on the integration with BW

Exception [EclipseLink-23004] (Eclipse Persistence Services - 2.0.2.v20100323-r6872): org.eclipse.persistence.exceptions.TransactionException

You have it set to run on the WebLogic platform so it is looking up the TransactionManager from JNDI, but are running the test from within the EclipseIDE. Try deploying it to Weblogic and running it there, or change your persistence.xml settings so that it can connect/run outside the server.
