Executing a MS Assess Data base using exec() problem

I am trying to run an access database from java. I would also like to pass it a command line argument. My code is as follows:
Runtime rt = Runtime.getRuntime();
String fileName = "c:\invoices\aspen\aspen.mdb " /cmd "100"
Process ps = rt.exec(new String[] {"cmd.exe", "/c", "start", fileName});
Every time I run the application, it opens a command window but does not run the access database. Can anyone shed any light on what I am doing wrong.
Thanks.

Newbie here. Sorry for the misunderstanding. The problem I am having is with formating the fileName string. When I do "start: c:\invoices\aspen\aspen.mdb" from the command line, it works fine.
I am having problems formating the fileName parm that is listed on the exec(). I need to point to the correct path where the mdb is located, and also, add the suffix "/cmd 100" where 100 is a command argument that access accepts and act on.

New Data Basis using infocbe 0BCS_C11

Hi,
I am creating new data basis using Infocube 0BCS_C11 in SEM BCS 4.0. Data Stream has been generated properly. Company and Consolidation Profit Center has been assigned Role ''Consolidation Unit'.
However, I am not getting Company as characteristic in 'Authorization/Validity check' tab. I can see:
Consolidation Group
Consolidation Profir Center Group
Consolidation Profit Center
We are using Infocube 0BCS_C11 as we think that in future we might use Matrix Consolidation, though there is no current requirement. At present we are going to use Legal Consolidation only.
Can you please advise?

There is a database toolkit for LabVIEW. I don't think it is a free download however. With the Data Manipulation toolkit, you can integrate with most databases that use the ODBC protocol.
If you don;t need anything fancy, you can write the values out to file using the write/read spreadsheet VIs. If the file is [COMMA] or [TAB] delimited, you can import it into your database with ease.
Another approach is to format you output to a text file as SQL, and import the records that way.

Not filling data in data base using Idoc

Hi experts,
I have a problem while filling data to data base table. My issue is
I'm transferring data from c4c to crm, when customer filling the custom fields in header level for contacts in C4C, the idoc structure is filled but when I look the database table but000 the custom fields values are not updated.
Thanks,
Ashok.

Hi Ashok
What IDoc basic/extension and message type are you using? And what corresponding process code are you using in the inbound partner profile?
If you are using standard for the above, then definitely the custom fields will not be populated automatically - you will need to have custom logic in a relevant user-exit/BADI to extract the custom fields from the IDoc structure and populate it into the table.

Thanks for your help in advance.
Indira

Hi Indra,
Request you to go through the below link in which anoop has beautifully explained the various ways to schedule the jobs.
http://scn.sap.com/docs/DOC-34648
In particular, I would request you to go through "Scheduling using Web service" Part. In this part, Anoop has shown how to publish the jobs and in the subsequent steps showed us how to call the webservice in the Query transform.
In his example he took two query transforms to execute the job sequentially.
If you wann to execute the jobs parallel then just check by calling both the webservices in a single query transform.

Acknowledgement from third party data base using receiver jdbc adapter

Hi ,
I've a scenario where I'm sending material master data to third party database using an automated scheduled prgram in R/3 , i've used asynchronous abap proxy to receiver JDBC scenario. But now they are asking to design in such a way that there should be an acknowledgement to the sender if data has not been updated in database.
pl help me how to design the above .
pointe will be rewarded
thanks
mojib

Hi mohammad,
In the design (IR) when u r specifying the messages interface define it has synchronous message there u will get the reponse message tag below the actual message interface. Here you can define the reponse message frm the thrid party if the message got failed.
Try do this with help of integration senario in which u can define the reponse(which is failed) also..............

Data pump using network_link problem

Hi,
I defined a database link for the sys user as:
create database link xe_remote
connect to hr
identified by hr
using 'xe_remote'
and it works fine:
select * from dual@xe_remote
D
X
Then, tried to import with data pump the user hr from xe_remote in the local system, but it seemed that the database link wasn't valid anymore:
impdp system/pwd schemas=hr network_link=xe_remote remap_schema=hr:hr_remote table_exists_action=replace
ORA-39001: invalid argument value
ORA-39200: Link name "xe_remote" is invalid
ORA-02019: connection description for remote database not found
Thanks,
Gianluca

Hello
oerr says:
oerr ora 39149
39149, 00000, "cannot link privileged user to non-privileged user"
// *Cause: A Data Pump job initiated be a user with
// EXPORT_FULL_DATABASE/IMPORT_FULL_DATABASE roles specified a
// network link that did not correspond to a user with
// equivalent roles on the remote database.
// *Action: Specify a network link that maps users to identically privileged
// users in the remote database.
Solution:
Create a db link from hr_remote to hr
or
Create a db link from system to system (I think, it's easier, because you have all rights...)

Problem of security using ADO from Labview to connect to Access 2000 Data Base

I have a problem using ADO from Labview to connect to Access 2000 Data Base.
First I open a ADO_DB_Engine and create a Workspace as an ODBCDirect. After I execute the open_data_base using the workspace. Here you can specify the parameter connect with /type of connection / user / password.
The problem is the following:
Although you configure a password for the Administrator user in Access, you can read/writte to data base from Labview using ADO without any security and without putting the user and password in the parameter connect. I need to access with security to data base using users and permissions but it seems that the parameter connect does not operate.
I attach
you a example of the vis and database. Remember create a ODBC connect with BD3.mdb
Thanks a lot

Hi Kahn,
If you use ADODB_connection -> Connection.Open and set in connection string :
"Provider=Microsoft.Jet.OLEDB.4.0; Jet OLEDBystem Database=c:\.....\Protegida5.mdw; Password=pepe;user ID=jose; Data Source:c:\......\BD5.mdb";
and after connection.execute ->
INSERT INTO tabla1 VALUES (5,'XXX'
you will be able to access to the database with security using the provider=Microsoft.Jet.OLEDB.4.0. With this provider you have to use the path and the name of the database file c:\.....\mdb file. From this way the problem is solved. (SEE SAMPLE_ADO_W2_JET.VI).
BD5.mdb have the following administrator user: user:jose / passwordepe (Protegida5.mdw)
The problem is when you want to
use ODBC and DSN. The name of this ODBC Provider is MSDASQL;. If you use this type of connection you can not enter to the database I attach you.
This database has a new administrator owner. I deleted the default administrator. If you support the default administrator you can connect to database by ODBC / DSN but the security disappear because you can always enter to database with any password, user o PC.
FINALLY I HAVE 3 QUESTIONS FOR Application Engineers of National Instruments or someone who knows these subjects before deciding the best way to connect locally o remotely with security to Access from Labview:
1.- Is it possible to enter to Database BD5.mdb from ODBC and DSN with this owner?
2.- I want to connect remotely to Access database too. Is it possible to use Microsoft.Jet.OLEDB.4.0 using the path (.mdb file) without DSN?
3. Which is the optimal Provider for Microsoft Access?
I thank you beforehand for your technical support.
Peter Mst.

Enforcing integrity using oracle specific data base commands .v. using fron

Full subject : Enforcing integrity using oracle specific data base commands .v. using front end.
It ought to be generally accepted that it is better to enforce integrity directly in the data base using constraints, dependencies, triggers etc rather than leaving it to specific front end programmes.
In my view, the chief advantages - of enforcing integrity directly in the data base - are:
(1) No process can violate the integrity.
(2) Being server centric, these commands run on the server and so can be easily sized in one place.
(3) One time data migration (imports) into the system using Oracle tools or SQL commands would also need to conform to the integrity constraints. Thus an implementor would be assured that the basic data is alright.
I am faced with a situation where we are about to implement a new Oracle based package. During data migration, when we discovered that there are no integrity constraints built into the target data base, the package vendor asserted that it is not necessary to build in integrity into the database. This seems to be an extreme and risky view.
Further, it is argued by the package vendor that putting constraints directly in the data base would significantly increase the needed resources (RAM) on the server. In my view, this increase is trivial and anyway, hardware costs are crashing day by day.
In the absence of integrity checks in the data base, it seems to me that every program would have to extra zero value work to ensure integrity of the end user data. It will still never be complete.
I would like to know the pros and cons of implementing without integrity constraints.
OK.

OK.It's a shame you seem to be so far into the process and committed to this vendor. I once had a vendor tell us his product would run on Oracle but they recommended MS SQL Server because "oracle can't handle more than 5 concurrent sessions." I made sure that vendor didn't make the short list.
