: How to find the system(machine) in the domain (network)

Hi Everybody,
Can some tell me how can i find the machines(system's computer's ip address)that are their in the network.
Iam developing a small program in Java, which i want to know the m/c's that are there in the network (or domain).
well anything even with ntive program that gives me all the ip's or m/c name as return will do.
Thanks in Advance.
Amit

I have not tried this in java, but the theory is the following:
In IP: if you want to receive response from all machines in your network, you would do the following:
(I will take a class C network as example)
Network: 192.168.1.0
Ping 192.168.1.255 (this is the broadcast address).
This way, all machines should respond. I think it is the ICMP protocol you use to do this.
The other solution (not Ethernet, and I think impossible with java) is to make a layer 2 (data link layer) broadcast rather than a IP (layer 3) broadcast. This can be done with a special MAC address code used to broadcast.
However, the first method should work for you, now the big question. How to use ICMP in java?
Regards... Martin

How to find the Source system table

Hi Experts,
How to find table name in SCM APO system, because I am getting error in process chain, the corresponding table in the source system does contain any data. check the data basis in the source system.
Please provide the solutions how to find the table in APO (DP scm bi).
Thanks in advance.
Bye,
Bharathi.

Hi
I guess you knew that in APO, apart from APO tables.. it is Livecache where the actual transaction data is stored.
But, if you just want to find some of the existing table in APO.. simply go to se11 and in the table name put the pattern as /SAPAPO/* and press F4. It will give a list of tables with the descriptions.
You can find out yourself all APO tables application wise with the following steps:
Use transaction SE11 or SE16
- Press F4 in the selection field
- You will get popup... in the below line of the popup selection SAP Applications.
Here you will get the Application list. In that select your own application for which you want to get the table details
e.g. SCM- Supply Chain Management --> SCM-APO --> Advanced Planning and Optimization --->SCM-APO-MD - Master Data --> /SAPAPO/00_PRODUCT
Here are some examples:
/SAPAPO/v_matloc - material, material number location view
/SAPAPO/TSAREAKO - Planning Area details
/SAPAPO/TSAREATE - Planning Area technial fields
Since there are thousands of tables, I cannot list them all here.
or
You can use transaction ST05 (database trace) to help you find the tables you are looking for. You can turn on the trace function, run an APO transaction, and looks at the ST05 logs for the tables

How to find the Data source name on linux server

Hello All,
Good Morning...
I created a rpd in my local machine and deployed on the server through Fusion middle ware.
and copied the catalog file there in the server.
While working on my local machine I have two odbc connections... one is for development and other is for production.
at the time of deployment to the server I changed the development instance to production instance throught the connection pool.
I am encountering the following error while working on the analyis....
Odbc driver returned an error (SQLExecDirectW).
Error Details
Error Codes: OPR4ONWY:U9IM8TAC:OI2DL65P
State: HY000. Code: 10058. [NQODBC] [SQL_STATE HY000] [nQSError: 10058] A general error has occurred. [nQSError: 43113] Message returned from OBIS. [nQSError: 16001] ODBC error state: IM002 code: 0 message: [DataDirect][ODBC lib] Data source name not found and no default driver specified. (HY000)
I think this is because of the mismatch of the datasource name in server and my local machine...could you please tell me how to find the datasource names on the server?
Thanks!

Hi Dpka-
I created two ODBC connections in my system.
one for development and another for Production.
while deploying the rpd to the server I changed the development login credentials with production login.
The problem here is I just want to know whether Iam giving the same datasource name which was presented on the server or not.
I don't have access to the server now.
Is there any way to find out the datasource names which were presented on the server with the help of admin console?
Thanks!

How to find the number of fetched lines from select statement

Hi Experts,
Can you tell me how to find the number of fetched lines from select statements..
and one more thing is can you tell me how to check the written select statement or written statement is correct or not????
Thanks in advance
santosh

Hi,
Look for the system field SY_TABIX. That will contain the number of records which have been put into an internal table through a select statement.
For ex:
data: itab type mara occurs 0 with header line.
Select * from mara into table itab.
Write: Sy-tabix.
This will give you the number of entries that has been selected.
I am not sure what you mean by the second question. If you can let me know what you need then we might have a solution.
Hope this helps,
Sudhi
