Regarding Connectivity

Hi Gurus,
I have requirement like , Non SAP System ( VB.Net ) need to call the SAP sytem through a particular DLL and get the result from the SAP. As of now that DLL calls a stored procedure and get connects to other system.
Please let me know what will be the best way to connect the SAP.Can i write any Stored procedure in Oracle( SAP's Database) and call from the DLL which is in another system .
Regards
Vikranth

Hello Vikranth,
there are several ways to connect you .net application to SAP either to get data or send data to be processed and stored. With the latest ERP versions, the best approach is a webservice generated from RFC function module. You could use the DCOM Connector, but it's an old technology (though not obsolete) which works using a DLL (the DLL will be referenced on your .net app, and though it you call RFC function modules)
Check this [video|http://www2.um.edu.uy/mhobbins/sdn_forums/complete_demo.zip] to see and end to end demo to get a webservice going and how to use it. A short intro before you watch the video: I made a simple RFC, it receives an ID, and returns two variables: name and surname. Only valid ID is value "1", and that will return name=Michael and surname=Hobbins. The demo starts on Tx SE80 building the webservice (notice I don't check the activate webservice just because it didnit work when I tried to when we started working with webservices). With the webservice created, I activate it from Tx WSCONFIG, from there I move to SICF to add the user and password I want it to run with, and finally check for the webservice URL by testing it and adding "&wsdl=1.1". From there I move on to VS2005 and reference and call the methods provided. Code on VS2005 is C#, if you can't follow and recreate for VB.NET, tell and I'll post an example for VB.NET.
Hope this gets you started
Cheers
Michael

Regarding Connection to ECC 6.0

Hi All,
This is regarding connection to ECC 6.0
I have created a system in
System Admin ---> System Landscape --> My_Folder
For the system I have given the foll. parameters for Connector
Application Host
SAP Client
SAP System Id
SAP System Number
Server Port
Do I need to give something else in order to make the connection with ECC 6.0
Also how do I test the connection.
Please help. It's urgent.
Regards
Nikhil Bansal

Hi
When I am testing for the Connection then I get the foll. Results
SAP Web AS Connection
Test Details:
The test consists of the following steps:
1. Check the validity of the system ID in the system object
2. Check whether the system can be retrieved
3. Check whether a SAP system is defined in the system object
4. Validate the following parameters: WAS protocol; WAS host name
5. Check HTTP/S connectivity to the defined backend application
Results
1. The system ID is valid
2. Retrieval of the system was successful
3. The system object represents an SAP system
4. The following parameters are valid: WAS Protocol (http) WAS Host Name (xyz14.xxx.com:8000)
5. HTTP/S connection failed
Seems the WAS Host Name is valid.
What does HTTP/S connection failed mean.

Questions regarding Connection Pooling

Hi
i have some confusion regarding how connection pooling is implemented..i have been doing some digging in to this lately but the more i read the more confused i get. i have some doubts here, will any of the posters here kindly clear them
a. Do i have to connect to my database via the DataSource method to take advantage of the connection pooling provided by my app server?..i have read conflicting information about this suggesting that Connection Pooling will not be provided to my app if i use DriverManager.getConnection()
b. if i chose to use the DataSource method do i have to implement the ConnectionPoolDataSource interface to provide the connection pooling for my app?
c. what is the best way to implement my own custom Connection pool?
Thanx

DriverManager.getConnection() literally creates, that is, builds a connection to the database using the values you previously supplied when you loaded the driver.
A connection pool is an object that contains several already made connections to the database, and simply provides you with one of those existing connections. The confusion arises because a) the method name is frequently the same and b) the connection pool object calls the driver's getConnection() method to create several connections before lending any of them out.
In other words:
DriverManager.getConnection() builds a connection to the database.
ConnectionPool.getConnection() fetches an existing connection.
So, to answer your questions...
A. This is correct. If you use DriverManager.getConnection(), you are indeed bypassing the Connection Pool entirely.
B. I'm not familiar with DataSource specifically, but in general, a third party connection pool will either give you the interface (and you implement the details) or they will give you the class file containing the DataSource object. All you would have to do in the latter case is to import that file, then create a new instance of it using the new keyword ( DataSource foo = new DataSource(); ). I suspect DataSource is indeed the class file.
C. Creating a connection pool is trivial and there are many examples of it - search on this forum or check out your favorite Java/JDBC programming book. Usually, the question "Should I use a connection pool and why?" is a more important question.

Regarding Connecting Two Systems

HI,
I hav a doubt, is it psbl to connect Non-SAP System with SAP System through ALE for data transfering, If it can be done can anyone pls send me the details.
Any suggestions will be much appreciated.
Thanks and Regds
Ramesh.

Hi,
The ALE concept involves using external converters to connect non-SAP systems to the R/3 System. External converters are generic format conversion programs.
They have the following properties:
the transfer of R/3 intermediate document (IDoc) formats straight into their own repository so that these data descriptions can be used as source or target structures when assigning data fields.
adoption and conversion of intermediate documents from R/3 Systems via the ALE interface - a remote function call that can be called up using a normal transaction.
conversion of any data format into intermediate document structures and import into the R/3 System via a remote function call (RFC) in the ALE interface.
ALE converters enhance the concept of EDI subsystem interfaces by:
using direct program-to-program communication instead of a file interface to transfer IDocs
recognizing the format of any interface structure of a non-SAP system and not just standard EDIFACT or ANSI-X12 formats.

Maybe it helps if you select the level and the complete path, like this:
SQL> with student as
2 ( select 'a' name from dual union all
3    select 'b' from dual union all
4    select 'c' from dual union all
5    select 'd' from dual
6 )
7   select name
8        , level
9        , sys_connect_by_path(name,' --> ') scbp
10     from student
11 connect by prior name > name
12 /
N      LEVEL SCBP
a          1 --> a
b          1 --> b
a          2 --> b --> a
c          1 --> c
a          2 --> c --> a
b          2 --> c --> b
a          3 --> c --> b --> a
d          1 --> d
a          2 --> d --> a
b          2 --> d --> b
a          3 --> d --> b --> a
c          2 --> d --> c
a          3 --> d --> c --> a
b          3 --> d --> c --> b
a          4 --> d --> c --> b --> a
15 rows selected.Now it shows you are building up 4 trees. One for each record, because there is no "start with" clause specified. And then the tree is built up using the clause "prior name > name", resulting in that output.
Hope this helps.

Rob.

Regarding connectivity to IR studio after installation of excel addin

Hi Frnds,
Iam facing a issue i have installed interactive reporting for a user and then later i have installed excel add in.
Before installing excel addin user was able to connect to essbase cubes before through brio but later installing excel add-in he was unable to connect essbase cubes through.
What would be the issue
Thanks,
KRK

Hi,
You may try the following---
Go to 'My Computer'---> Right Click----> Properties---> go to 'Advanced'---> in that, open 'Environment Variable'---> In the list, find 'ARBORPATH' which should only contain value '<<Drivename>>:\Hyperion\AnalyticServices'
If there is any other value, you may remove and save it and come out of that.
After that, please check whether the IR and Excel add-in both working fine. Please let me know it works or not.
Thanks & Regards.

Regarding Connection In Xcelsius

Hello Experts,
I have about 10 connections in my Xcelsius dasboard. Now my requirement is untill all connection got active and load the data till that i have to show the loading screen and rest all part off dasboard will be disabled. How do i know that my all connections loaded the data successfully.
Thanks in advance

For each connection you can let XCelsius write a number, let's say 1, in a specific cell when the data is loaded.
You can have a formula in another Excel cell that sums up the values from the loading status cells. Create an additional formula in a different cell to return 1 unless the value of the sum up field (sum of the loading status cells) is 10. In this case it should return 0. LEt's call this TriggerLoadingScreen cell.
Create a loading screen (eg. a JPG) that covers the entire dashboard (put it in the foreground). Setup the visibility of the loading screen to be based to the value of the TriggerLoadingScreen cell.

Stratos

You will get this under the following circumstances:
(1) The process at the other end has crashed.
(2) the other end has closed after messing around with SO_LINGER.
(3) you have sent data to the other end after it has closed its socket.

Regarding Connection Time Out issue in Webservice call to database.

Hi,
We are facing one issue with the webservices call to DB and ILOG. We are declaring and executing the webservice in the following way-
//Request Object
EDP.ILog.PEWM_EXPDOC_Help_Information_ProxyService.DecisionServiceRequest helpRequest = EDP.ILog.PEWM_EXPDOC_Help_Information_ProxyService.DecisionServiceRequest();
//Response Object
EDP.ILog.PEWM_EXPDOC_Help_Information_ProxyService.DecisionServiceResponse helpResponse = EDP.ILog.PEWM_EXPDOC_Help_Information_ProxyService.DecisionServiceResponse();
//Proxy Service Object Initialisation
DecisionServicePEWM_EXPDOC_Help_InformationService helpService = DecisionServicePEWM_EXPDOC_Help_InformationService();
helpService.executeDecisionService(parameters : helpRequest, out parametersOutput : helpResponse);
All the webservices are configured corectly in External Resources of Process Administrator. Now, the issue is that whenever we are trying to execute the service with good amount of load on OBPM Process Admin Engine, it is throwing the following exception-
"Exception:java.net.ConnectException: Connection timed out: connect"
We are unable to find the root cause of the issue as the webservices call is still throwing the above exception.
Please provide some resolution as soon as possible.
Thanks in advance,
Abhishek

Just to be sure, we're talking about a client process in BPM accessing an ILOG web service or a DB web service, right? Is this DB web service something custom built?
Be aware that certain things can run inside the workspace and not the engine. You almost have to work at making this happen. The easiest way is to make this happen is to invoke a BPM object method from within a BPM object presentation or JSP. If you do have this situation open the BPM object method and click on properties and check the box run on server side.
I can't think of anything that wouldn't scale for connections to Web Services in an engine. I'd be looking at tuning your ILog Web services. Perhaps it can't keep up and the engine gets a timeout. How often does this happen? The engine should retry the automatic until is works. But it tries 3 or so times, it gives up. This retry is configurable.
HTH,
Mark

Urgent regarding connection pooling

Please can someone thorw some light on how to implement connection pooling in simple way. I have seen lots of code snippet and did lots of reading.
I need to know about how many classes i would need. and how do i use the classes.
If someone can provide code snippet then that would be great
thanks..please consider it to be urgent.

Why reinvent the wheel?
Most JDBC drivers will have connection pooling already implemented, and you just need to use it.
You should be using the interface javax.sql.DataSource
http://java.sun.com/j2se/1.5.0/docs/api/javax/sql/DataSource.html
The recommended approach in Java/JSP is to have a DataSource object accessed via JNDI.
Most servlet containers will let you define JNDI datasources to access the database connections from your app.
For instance Tomcat: http://jakarta.apache.org/tomcat/tomcat-5.0-doc/jndi-datasource-examples-howto.html
Good luck,

Query regarding connecting dashboards with SQL DATABASE using WSDT

Hello Sir,
I am trying to connect dashboards with Sql database via WSDT, but i have encountered the same problem as described in your SAP community blog (SAP Web Service Design Tool: From web service creation to Xcelsius consumption).
when i tried connecting CR server with WSDT ,it still shows that total number of available licenses is 0.
What can be done to solve this issue.
for your detail reference, we are using CRS NUL version's 60 days Evaluation keys and same with Xcelsius Departmental edition.
I would really appreciate, if you revert back to my mail as soon as possible

Which version of Crystal Reports are you using? The regular ReportDocument SDK probably isn't robust enough to handle this, unless you create a connection using that connection string at design-time which you don't change at runtime. You might be able to add those properties using the in-proc RAS SDK, though. This is available with CRXI R2 as of SP2, and CR2008.
