We actually do this with many of our big active files.  Many benefits to 
distributed files when it comes to maintenance :)

The file in question here is a deep archive file which will see little activity 
and, once it's sized properly, will *hopefully* never change again.

Subject: Re: [U2] [UV] RESIZE INPLACE

Hi,

Given the risk of manipulating a file of this size, I recommend the use of 
distributed files (DEFINE.DF).
Just as effective, if not better, each part file is administered individually 
(backups, resizing, indexing, !accessing, locking,...)

Procedure :

1 - analyse the keys to build a distribution algorythm ; at worst use hashing 
algorythm ; don't forget a elsewhere partnumber (1 ) 

2 - create part files (define how many, size, ...,  by analysing number 
key-records, time growing ,...)

3 - define distributed file ; DICT adress the original DICT

4 - copy all record from orig.file to df.file (do it one time before live to 
check if all keys can be processed by your algorythm)

5 - edit VOC orig.file to adress df.file as data file

6 - resize all part file individually.

7 - delete the orig.DATA file &index from os ; to get back your 144gb

My two pence
