wait for file activity is perfect for you.
I presume wildcard doesn't work here. You should have a specific file name.

Clarification do you have server on the machine where the file arrives?

I a routine you can open the directory like a hash file.

Code: Select all

Ans = @FALSE
DirName = Arg1
FileName = Arg2
openpath DirName to MyDir then
   read Rec from MyDir, FileName then
      Ans = @TRUE
   end
end

I gave you a routine to find one file. You should be able to find the next 39. We are not here to do your job. Just point you in the right direction.

Hello Sir,

I will give clear explanation here.

I have path of files like this \\data\USA\Processed.txt or
\\data\IND\Processed.txt
\\data\RUS\Processed.txt
\\data\CAN\Processed.txt
\\data\BRT\Processed.txt
.............................
Like this for 40 countries.If any on of the file exits i have to abort the job
before the jobX.
Is there any DOS command to find the file path like this

\\data\*\Processed.txt.

Please help me on this.

Thanks
Narasa

Take a good look at the "dir /s Processed.txt" command in dos, this will give you a list of the files found. You can write a Function that calls this command and gets the result in a string.

There is a little-known utility that ships in the DataStage bin folder. The utility is called uvwalk and can perform a treewalk in a directory structure, much like find does in UNIX.

This might provide a more flexible solution.

Get to a DOS prompt and execute uvwalk with no command line arguments; it will issue a "this is the correct syntax" message showing you the options.

Why should uvwalk be different from any other operating system command?

If you expect some help, you might want to explain what 'not working for me' means.

What you've tried, what error message you've gotten, that sort of stuff.

(I wonder, how many posts in a row can we get with rolly eyes in it?)

I could not find uvwalk in the bin directory,if searched in

Code: Select all

/ds/Ascential/DataStage/DSEngine/bin

(i cant stop rolling my eys)

Kumar,

I have 7.5.1 on AIX and couldn't find it either, perhaps Ray is referring to a Windows-only executable... especially as UNIX does have a "find".
