segmented file name

  • Follow


Hi,

if you have "Limit Segment Size to 2 Gb" set to ON, Pervasive will
split your files, if they grow upon 2GB, into files named filename.^01
filename.^02 and so on.

This will be OK until there are more than 100 segments.

In PSQL9 there is a limit of filesize of 128 GB, so there is no
problm, because there never more than 64 segemtns, but with 10.3 the
filesize limit is 256GB, so we can have up to 128 segments.

Does anybody know, how they will be named?
may be filename.^A0 filename.^A1 ...
or filename.^001?
I dont know.

Files are named in hexadecimal extensions, not decimal.  So, after ^09 
comes ^0A, ^0B, through ^0F, then ^10.  With this naming scheme, there 
is room for 256 segments, or 512GB total file size.

Currently, the maximum file size is only 256GB, so there's LOTS of room 
for growth.
