Using FTP to Move Structured Files Without Causing Corruption

Using FTP to Move Structured Files Without

Causing Corruption

Symptom

After using FTP to copy structured files from one NonStop server to another, the

target file is corrupted.

Version

All.

Problem

Using FTP products other than those designed to move structured files between

NonStop systems results in a corrupted target file.

Fix

Use the NonStop systems FTP client to move structured files, such as

key-sequenced, relative, and entry-sequenced files, between NonStop servers.

To ensure that structured files are correctly transferred, you must first issue the

FUP INFO command using the DETAIL option for the file you wish to transfer. All

file attributes that are present in the display must be included in the get (or put)

command.

Note: If the file you want to copy is a structured file containing embedded

<CRLF> character sequences, you must first issue the stru command with the r

option. For more information about the stru command:

In G06.20 and later, see the NonStop TCP/IP Applications and Utilities

User Guide.

In G06.19 and earlier, see the NonStop TCP/IP Applications User Guide.●

Example

This example copies a remote key-sequenced structured file, named KEYSEQ, to the local

NonStop server.

Before starting the FTP session, obtain a detailed listing of the file:1.

100>FUP INFO KEYSEQ,DETAIL

$ABC.SOURCE.KEYSEQ (file name)

ENSCRIBE

TYPE K (filetype)

CODE 1001 (filecode)

EXT ( 5 PAGES, 5 PAGES) (primary and secondary extents)

REC 60 (record-len)

BLOCK 512

IBLOCK 512 (index_blk_len)

KEYLEN 4 (pri-key-len)

KEYOFF 0 (key-offset)
