ABAP Unix

Hi gurus,
In my requirement i need to write unix script also along with abap .. i still did not get any spec for this so to give more information to you.
But i never worked Unix and abap together...
Can you pls tell me why and when we use Unix scripting with ABAP?
how can we use UNiX in SAP system?
any sample unix scripts... will be appreciated..
Thanx in Advance
Giri.

I don't send PDFs around.
"Unix" is a generic Term for an operating system (see http://en.wikipedia.org/wiki/Unix).
Since I don't know why you need to execute Unix scripts from SAP I can't tell you what you need to do in order to accomplish that. I can just say, that it's possible to do so (external commands using transaction SE49).
It can be used to e. g. copy files to a (non-SAP)-System, do FTP and many other things.

Small question related to Unix and ABAP

Hi Guys,
I had a new SAP ABAP requirment in which they are asking for unix shell scripting.
I am just wondering as what unix shell scripting has to do in SAP ?

Stop CIF queues always during online Backup on SCM system

Hello,
On Upgrade Guide "SAP SCM 5.1 ABAP UNIX Oracle Version 1.00" under
chapter 3.4 --> Backup before prepare JAVA we found this :
"Before performing a database backup, you have to stop the CIF queues in your
SAP SCM system in order to ensure a consistent recovery state."
Is this relevant for every online backups (also outside from Upgrading)?
Should we stop the CIF queues on daily online backups too? Or is this a special-feature during Upgrade?

Hello,
Do you have above said log file available ?
Instead of the option 'Overflow log path', did you try rollforward with the option of timestamp (point in time) (till the time you have the log files) Or with the option overflow log path but with 'NORETRIEVE' as well ?
For the query status command, Last committed transaction time stamp is not what you thought.
Please revise the command options,
http://publib.boulder.ibm.com/infocenter/db2luw/v8/index.jsp?topic=/com.ibm.db2.udb.doc/core/r0001978.htm
'It is looking for log file S0000XXX.LOG whose time stamp is older than the time stamp of online backup.'
If you want to restore only until the online backup, then use the option End of Backup and stop - to rollforward until the last log when backup was in progress
Thanks

UNIX command in ABAP code

Hi All,
I need to use unix command (MOVE) in ABAP code for transfering a file from one directory to another directory.
Can any one help with how to used unix commands in ABAP?
Thanks in advance.
Regards,
Hemendra

The recommended approach always used to be to use transaction SM69 to define a "soft" command name to the operating system command so that it could be configured to work across Windows, Unix etc. For example:
Command name OS Type OS command Parameters for operating system command
Z_FILE_MOVE SunOS Customer mv ? ?
You can then call function module SXPG_COMMAND_EXECUTE (quite well documented) to actually perform the command passing in the appropriate number of parameters.

1 But when i run it using call 'SYSTEM' .. i get message security risk , command not executed ..
2 I also created the command in SM69 and tries to run it but same error.
3 I also created a shell script , but i get another message when i try to run sh ...
Please help to find out a way to make it work ..
Kunal

Hi kunal,
1. probably ur basis team might be able to help u.
2. even if we have authorisations thru sap
   to run external os command,
   the actual OS user on application server
   must have the right for it
   and access/write/read/modify
   for the files (provided thru the command)
   in question.
3. Due to this , the systems gives the message
   of SECURITY RISK.

How to generate a empty file in AL11 using ABAP and unix command

Hi Experts,
when load infopackage triggers it will search file from AL11 if file is available it will get loaded successfully. When there is no file in AL11 error while opening file (orgin A) and the load will fail. At this level i have to write a abap code using unix command to generate a empty file.
Is there any way to achieve the above requirement.
Thanks
Vara

Hi,
If i get your requirement properly then you want to create a blank file if there is no file on the application server so that your infopackage does not fail, am i correct.
If this is your requirement then this can be easily done if you use process chain to load the file via infopackage. Follow the following steps:
1. Add a ABAP program before the infopackage and check if the file is present on the server or not. Use a simple ABAP statement OPEN DATASET <FNAME>. Check the SY-SUBRC after this statement if it is not 0 then it means that the file does not exist on the application server.
2. Once you have established that the file is not present create a flat file using a code similar to the below one
OPEN DATASET FILENAME FOR OUTPUT IN TEXT MODE
MESSAGE D_MSG_TEXT.
IF SY-SUBRC NE 0.
WRITE: 'File cannot be opened. Reason:', D_MSG_TEXT.
EXIT.
ENDIF.
* Transferring Data
LOOP AT INT_table.
TRANSFER INT_table-field1 TO FILENAME.
ENDLOOP.
* Closing the File
CLOSE DATASET FILENAME.
3. Add your infopackage step after this ABAP program in your process chain.
I hope this helps.

Kush Kashyap

Trying to print ABAP List in Unix

I am new to SAP and I am trying to print using unix as my host spooler. I am printing to a Xerox machine connected to a print server. I am just trying to print the test ABAP list you get when you go into SPAD and select Utilities/ouput devices then select ABAP List. When I print this I get nothing but ABCD and a bunch of numbers. I am trying to figure if the ABAP list is supposed to be that way or if something is wrong with my driver.

Hello Rodney,
What device type did you specify in the SPAD Output Device definition? You need to make sure you select a device type which is compatible with the printer. If the printer supports postscript printer language, then you need to select the 'Post2' or 'postscpt' device types. If the printer support PCL, then test with 'hplj4' device type. Most likely the currently selected device type is not compatible with the printer and therefore creates a print file which the printer cannot interpret.

Nathan

ABAP to FTP connect to non SAP UNIX system

Greetings~
I'm looking for a way (via function modules and/or BAPI) to transfer data in flat files from an SAP UNIX system to a non-SAP UNIX system using an ABAP program. I see FM's FTP_CONNECT and FTP_COMMAND however these seem to only work with UNIX systems running SAP as they require RFC_DESTINATION information. Anybody know which (if any) FM's can be used without the necessity of the target system running SAP/RFC?
Thanks!

Call ABAP program from Unix script passing dynamic filename

Hi,
Does anyone know if it is possible to call an ABAP program from a Unix script passing a dynamic filename to the ABAP program?
We are receiving a file from an external company and on receipt of the file want to call an ABAP program passing the filename. The filename is made up of File ID, Date and Time which we need to read in the ABAP program. We usually use Events to trigger a program which is fine when the filename if static however since this filename will be dynamic we cannot do this. In addition we cannot just rename the file to a static name in the Unix script as we need to know the value of the date and time from the file ID in the ABAP program. I can change the ABAP program to check our /in directory for a Filename that starts with the fixed File ID however I thought there must be a better way of doing this. We want the external company to put this information in a file header record but they don't want to change the file contents. Any ideas would be appreciated.
Thanks,
Sinead.

You could follow the following method
1.Let the external file reside in the SAP application layer in a defined path e.g. /usr/sap/tmp/interface/working/
2.Write an ABAP program which will include the following steps:-
i) read all files in the file path using function module EPS_GET_DIRECTORY_LISTING
ii) Read the data from files existing in the directory using OPEN_DATASET statement
iii) After the files have been read move the files to another directory e.g. /usr/sap/tmp/interface/backup/ or you can delete the file.
3.Schedule this program to be executed depending on the frequency of the external file being generated.

To execute from ABAP code an external Unix program

HI,
I would like to know how to execute from ABAP code an external Unix program and check for a return code?

HI,
There are different ways to this:
(1) OPEN DATASET <file> FOR OUTPUT 'unix command'
CLOSE DATASET <file>
This command executes the unix command and writes the output into <file>
Look into OSS Note 9391.
(2) or try the following program but unfortunately the command CALL SYSTEM is
not supported by SAP. If you are on R/3 2.1 - 2.2x you can get some idea's from the program SAPMSOS0.
REPORT ZUNIXCOM .
DATA: U_COMMAND(200).
Table for system messages
DATA: BEGIN OF RT OCCURS 100 ,
LINE(100) ,
END OF RT .
START-OF-SELECTION .
MOVE 'unix command' to U_COMMAND .
REFRESH RT.
CALL 'SYSTEM' ID 'COMMAND' FIELD U_COMMAND
ID 'TAB' FIELD RT-SYS .
LOOP AT RT.
WRITE : / RT-LINE .
ENDLOOP.
