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

Before I go and resize a 144GB file has anyone had any experiences with the
INPLACE option of RESIZE in UniVerse?  Good, bad, ugly???

Thanks.
