EBCDIC file handling

Sourcing the EBCDIC file from mainframes to Informatica can be a harder job! Verifying and managing the Packed decimals and the zoned decimals are as easy as the normal flat file handling. You should be in a position to know various flat file options to have it done!
In informatica to read an EBCDIC file VSAM source file strucure is used. Where we can prepare EBCDIC file from the flat file by the tool called 'Ultraedit'. To prepare from ASCII, first need to convert to EBCDIC format. Then to remove null spaces convert it to hex mode and serch and remove for "0D 25" with null. After that again return it to EBCDIC mode and this file with .TRX extension you can use for testing purpose.

Using a well known file enditor VEDIT ,the EBCDIC file can directly be edited without translating it and then can be transferred back to a mainframe computer. For transfering to a PC or a UNIX system particularly to a database such as SQL or MS Access, using VEDIT, the EBCDIC file can be translated to ASCII before transfer. The EBCDIC files that do not contain packed-decimal fields are particularly easy to translate to ASCII using the VEDIT.
