ApexМожно еще проще:
1) В типе файла указываете Command, а в свойстве Indirect File List источника указываете саму команду dir /b *.txt.

Обалденная фича :-)

Informatica KB Forward slash is converted to a back slash when using the Command Generate File List option with a flat file source

Problem Description

A session will fail when it has a source flat file that is configured with the Command generating file list option and the command text has a forward slash ("/") in it.

Example:
This occurs with the following command:

dir /b C:\Informatica\PowerCenter8.6\server\infa_shared\SrcFiles\*.txtRun a session with this command and it fails with the following error

INFO : (4196 | READER_1_1_1) : FR_3086 : Reading input filenames from standard output of the shell command [dir \b C:\Informatica\PowerCenter8.6\server\infa_shared\SrcFiles\*.txt].
INFO : (4196 | READER_1_1_1) : CMN_1937 : [SQ_jaco] Starting shell command [dir \b C:\Informatica\PowerCenter8.6\server\infa_shared\SrcFiles\*.txt].

INFO : (4196 | READER_1_1_1) : CMN_1951 : [SQ_jaco] Started shell command [dir \b C:\Informatica\PowerCenter8.6\server\infa_shared\SrcFiles\*.txt]. Process id is 2428.
INFO : (4196 | READER_1_1_1) : CMN_1948 : [SQ_jaco] Process id 2428. The shell command completed successfully.
INFO : (4196 | READER_1_1_1) : CMN_1954 : [SQ_jaco] Process id 2428. Standard output and error:
File Not Found

The command is converted to the following at session run time:

dir \b C:\Informatica\PowerCenter8.6\server\infa_shared\SrcFiles\*.txtThe file infa_shared/Temp/iPmCmd55_7_0_826 does not actually exist after the session run.


Cause

This is a known issue (CR 191249) with PowerCenter on Windows.


Workaround

Create a batch script to wrap the command and set the command as the name of the batch file.

Example:
In this example the following can be used in the batch file:

@echo offcd C:\Informatica\PowerCenter8.6\server\infa_shared\SrcFilesdir /b ff*.txt
