Hi..

We Are using Lytec a medical Billing Software...Which Uses Pervasive as its database..

We Have recently Converted Our Lytec 2001 to Lytce XE...

The size of some of the files tripled...


example...

File A
                                                Old Structure                                          New Structure
Record length                             892                                                      1105        


With The Number of records remaining the same..

The Size of the Files trippled

Before  220 MB..Now 660 Mb..

any suggestions on this...

That's  pretty significant increase.  How many records are in the table?  I created a table with an 1105 byte record, addeded 12,000 records and my table was only 880 KB.
Also, what happens if you rebuild the data file? Does the size drop?

Can you post a BUTIL-STAT of the file?  If the reseller says it's normal, then that's possible.  Especially if a rebuild didn't help.

THe most likely reasons for that significant an increase:

(1)  Page size:  In Btrieve, the default page size id 4096 bytes.  With the old structure, 4 records would fit per page.  The new only allows 3 records per page.  Automatic increase of +33 percent

(2) Indexes:  If there were a significant number of indexes added, this could easily add to the table size.  As a (bad) example, I have seen a reasonably large table with 20+ indexes go from about 700K to about 2MB just by adding indexes.

Lytec de-compressed the data files in the XE version. They were told that this would not affect the performance by Pervasive. However, this slowed down the reporting process in many cases. In the new 2004 version ther compressed the data files again. The file size that you are seeing is probably due to the de-compression
