Question related to performing R computation in database

I am trying an example something similar to the one mention in the following document
http://docs.oracle.com/cd/E11882_01/doc.112/e36761/using.htm#CEGJECHG
However, for me its always failing... Just wanted to check with if you were able to execute a embedded R computation e.g doEval which involved pulling a db table into a data frame ... I tried the following
ore.create(iris, table = "IRISEMBED")
head(IRISEMBED) //works fine
+//following command errors out+
newmod <- ore.doEval(
+function() {+
library(ORE)
ore.sync(table=c("IRISEMBED")) //also tried ore.sync()
dat <- ore.pull(IRISEMBED)
newmod <- lm(Sepal.Length ~ Sepal.Width Petal.Length, dat)+
newmod
}, ore.connect=TRUE);
Error in .oci.GetQuery(conn, statement, data = data, prefetch = prefetch, :
ORA-20000: RQuery error
Error in ore.pull(IRISEMBED) :
error in evaluating the argument 'x' in selecting a method for function 'ore.pull': Error: object 'IRISEMBED' not found
ORA-06512: at "RQSYS.RQEVALIMPL", line 104
ORA-06512: at "RQSYS.RQEVALIMPL", line 101
However , if try to execute the above steps one by one directly from R shell, it works fine... I am facing this issue only when try to pull a table as part of doEval function. Also, I get the same error from SQL also when I try to execute any R function which involves pulling a table into a data frame ... Any idea about this issue ?

Thanks a lot ! It worked.
It will be great if the documentation example can also be updated with it

Question related to project performance management

Hi,
We have implemented peoject management and project accounting module with Grants module for one of the semi public sector client. Now we are planning to enable project performance repporting.
I assume below things
1. If Grant is implemented, Project budgeting doesn't work
And
2. project performance reporting based on project accounting,project budgeting and project management modules.
If anyone of you have done similar requirement , Please let us know the approach your approach.
Thanks in advance

Performance with MySQL and Database connectivity toolbox

Hi!
I'm having quite some problems with the performance of MySQL and Database connectivity toolbox. However, I'm very happy with the ease of using database connectivity toolbox. The background is:
I have 61 variables (ints and floats) which I would like to save in the MySQL-database. This is no problem, however, the loop time increases from 8ms to 50ms when using the database. I have concluded that it has to do with the DB Tools Insert Data.vi and I think that I have some kind of performance issue with this VI. The CPU never reach more the 15% of its maximum performance. I use a default setup and connect through ODBC.
My questions are:
1. I would like to save 61 variables each 8-10ms, is this impossible using this solution?
2. Is there any way of increasing the performance of the DB Tools Insert Data.vi or use any other VI?
3. Is there any way of adjusting the MySQL setup to achieve better performance?
Thank you very much for your time.
Regards,
Mattias

First of all, thank you very much for your time. All of you have been really good support to me.
>> Is your database on a different computer? Does your loop execute 61 times?
Database is on the same computer as the MySQL server.
The loop saves 61 values at once to the database, in one SQL-statement.
I have now added the front panel and block diagram for my test-VI. I have implemented the queue system and separate loops for producer and consumer. However, since the queue is building up faster then the consumer loop consumes values, the queue is building up quite fast and the disc starts working.
The test database table that I add data to is created by a simple:
create table test(aa int, bb char(15));
...I'm sure that this can be improved in some way.
I always open and close the connection to the database "outside the loop". However, it still takes some 40-50 ms to save the data to the database table - so, unfortunatly no progress to far. I currently just want to save the data.
Any more advise will be gratefully accepted.
Regards,
Mattias

two questions related to this:
1. Why Java is designed to only permit single
inheritence, any stories behind the scene? I think
some major reasons why "prefer interfaces toabstract
classes" is accepted is rooted in this limitation.Yes, one of the reasons interfaces are better is that
you can only extend one class, but implement many
interfaces. Say you have a concrete class that should
"implement" two different types. If those types were
defined as abstract classes, you could only use one
type. You could implement both types if they were
interfaces though. So why java is designed to have this limitation? There may be some arguments before this is settled down. I always like to hear this kind of stories:)
2. Base on the fact that once an interface is outof
box and widely implemented, it is almostimpossible
to change it. So how you guys design yourinterfaces?
Could you share some? In my idea, I would designmy
interfaces as compact as possible.You could extend the interface and start using that
if you didn't want to break existing code. You
couldn't use that implementation as an Interface1
though, since the new methods only exist in
Interface2, so that's not an optimal solution.So we may always need to add a new interface when we just want to add a new method.

Basic Questions related EHPs for SEM

Hi Guys,
I've some basic questions related to EHPs: -
1. If we don't mean to implement any of the new functionalities does it make any sense to implement EHP? In other words do EHPs also have some general improments other than the functionalities which can be specifically activated?
2. If we just activate a functionality and don't implement/ use it can there be any negative impact?
3. In case of a pure technical upgrade from SEM 4.0 to SEM 6.0 which EHP would be recommended?
4. Is there a quick way to find all relevant notes in EHPn which are related to corrections for EHPn-1?
Thanks in advance,
-SSC

HI,
If you see some of my older posts I have had many issues with certain features of the EHP2 functionality but that doesn't mean I would recommned against it.
BCS 6 EHPs 3 & 4 (BCS 6.03 / 6.04) - enhancement packs worth implementing?
BCS 6 EHP 2 (BCS 6.02) - activation of enhancement pack
My recommendation is to implement the EHPs but not necesarrily activate the functions (in SFW5) unless you need them - this means that you will only have to test once after EHP implementation and will have the ability to activate the other features as and when required (although testing is required after activation of course) whereas it might be difficult to persuade your client/basis team to implement EHP4 later if you don't do it now.
In the features of EHP2 (activate FIN_ACC_GROUP_CLOSE) it states that there is a general performance improvement - although I have yet to experience it! From OSS note 1171344 "The functionality which is available in EHP2 consists of...
... Performance improvements of status management, reporting and initial start-up of consolidation workbench and monitor.
Since activating FIN_ACC_GROUP_CLOSE I have had many OSS notes requiring application but i discovered that when the technical team implemented the EHPs (before i joined this client) they somehow forgot the latest SP (support packs) and didn't upgrade to the current level - so make sure that you get the right SPs too (see the links in Greg's link above) to avoid the many OSS notes.
As for your question - "is there a list of OSS notes to specific to EHP upgrades? - the answer is most definietly "NO" - I already asked OSS in desperation!
however, you can see the OSS notes that i have applied listed in the above link ( BCS 6 EHP 2 (BCS 6.02) - activation of enhancement pack )

Question related to concept of PCK

Hi All.
I am quite a newbie to XI and am only learning it thru online help. I have one conceptual question related to PCK.
My understanding is that PCK is needed by a small business company to communicate to its larger partner which already has XI running. Correct me if I am wrong here itself.
Now if the larger business partner already has XI, why does the smaller one need a PCK at all? The XI instance on the larger partner will have all the necessary adapters to understand any format send by the partner. So even if the partner(smaller) sends any format- be it IDOC/HTTP/FTP, the XI instance on larger partner will have its adapters ready to perform the conversion.
Then why is this PCK needed at all?
Thanks in advance. Hope my query is clear
Regards.
Samant

Hi Samant,
Your question is a very good one, Though I have not worked on PCK, I can share my ideas based on some brain storming session I had with our collegues & business partners.
While executing projects, there are technical & operational issues. For example, when you access any HR related data of a UK based organisation then all those who work on that project have to undertake data security pledge. Like wise there are many constraints on data & system accesses, which vary across organisations.
When you use PCK*, irrespective of different systems what the small vendors have, you communicate with your Big company's XI system only on the XI's msging protocol http(s)/SOAP. This allows a fair amount of ownership of data/access related issues to the small partners.
-> you go for PCK, when there is no need for small vendors to go for XI.
Hope this is of some help. As Michal said there might be much more (or even better) reasons.
Michal, when you say "all of the mappings and transformations have to be on the small company side", what exactly you mean by this. can you please eloborate.
Thanks & Regards
Vishnu

Question related to Synchronous update

Hi, all
I have some question related to synchronous update:
1. What is the syntax if I want to write synchronous update.
Do i write as:
call funcition A in update task
commit work and wait
Or just
call function A (A declared as update type function )
commit work and wait
Or ...
2.If we use synchronous update, is VBHDR,VBDATA still filled the same way when using asynchronus update?
Thanks in advance,
Liming

Hi,
Why do we use this " In Update Task " ??
The main update technique for bundling database changes in a single
database LUW is to use CALL FUNCTION... IN UPDATE TASK.
How do we Use ??
A typical R/3 installation contains dialog work processes and at least one update work process. The update work processes are responsible for updating the database. When an ABAP program reaches a COMMIT WORK statement, any function modules from CALL FUNCTION... IN UPDATE TASK statements are released for processing in an update work process. The dialog process does not wait for the update to finish. This kind of update is called asynchronous update.
What is the Use... ??
Asynchronous update is useful when response time from the transaction is critical, and the database updates themselves are so complex that they justify the extra system load

Performance issue after upgrading database 9i (9.2.0.5.0) to 10g (10.2.5.0)

Hi,
recently we have upraded our database from 9.2.0.5.0 to 10.2.5.0. After the upgrading of the database some of our SQL-statements, who gather data and fill it in an empty tabless,
shows a really bad performance in the new database version. We already have checked the explain plan it remains the same in both versions (full table scans on the corresponding tables)
E.g. a query running in the 9i database needs 17 minutes for completion in the 10g version it needs 15 hours.
We have checked the running session and have seen that the read of database blocks of the corresponding tables needs immense more time in the 10g version.
Are there any oracle parameter, hidden features we can adjust in 10g in order to get the same performance as in 9i?
thanks in advance

PERFORMANCE while accessing remote database DB2 on AS/400 using WAS

Subject: PERFORMANCE while accessing remote database
We have IBMWebSphere Application Server Standard Edition 3.5.3 running on
AS/400 iSeries Server (V4R5, test)and local DB2 Database.
I am using AS/400 Developer Kit for Java JDBC Driver(type2, com.ibm.db2.jdbc.app.DB2Driver)
to talk to local database. The performance was very good.
When I try to access remote database (every thing same as local) which is on another AS/400
machine of V4R4 (we use it for production, remote database) using IBM Toolbox for Java JDBC driver
(com.ibm.as400.access.AS400JDBCDriver, type 4 driver), I can see 30to40%decrease in performance.
Here we have WAS on previous V4R5 AS/400 machine.
My questions are
Is the performance decrease is due to
1. the driver I am using? if it is Is there any other alternative drivers to access
remote database to boost performance?
2. the release difference of local(V4R5) and remote data base(V4R5)
3. Currently most uses remote database while we do this testing. Is that the cause?
or Is there any other cause or Drivers etc??? Suggestions and help is most welcome.
Thank you.

What about
4. the data has to travel across the network.

Q3)In client side - Can the outlook add-on for SAPCRM be enhanced for different business logic or look n feel?
Thanks,
Vicky

Hello Vicky,
1) Yes the Relate to SAP CRM function is part of Client-side groupware only.
2) The Add-in is only available with Client-side groupware.
3) The Add-in cannot be customized. However the results can be influenced by parameters in transaction GWIPROFILE.
The information displayed in the Business information Pane can be changed.
