{newbie}Powerhouse with flat file back end

[Boyle, Joe]

Hi Matt,

many PowerHouse users on Unix make extensive use of indexed c-isam files. 

A number are moving to Oracle due to the current c-isam file size limitation
of 2 gig within current versions of PowerHouse 8.23 which makes use of the
c-isam release 7.1.2.

However, new releases of PH ( 8.4 and higher ) will take advantage of the
new c-isam releases (7.2.5 and higher) which allow for a much increased file
size limit. 

At this time it is thought that the new c-isam release will be supported on
platforms Solaris, AIX and HPUX, but it will be included wherever it is
available as and when development permits.

My company is investigating use of a powerhouse application that uses a flat
file back end on HP-UX UNIX.

<questions type=newbie>
I seem to be the only one that thinks this is a problem.  In this day and
age this seems pretty archaic to me.  Has anyone had experience with such a
system?  Are there scalability and file locking issues?  What about
contention and/or possible corruption of files?

Not knowing much about it does PH talk directly to the files?  Or does it
use something else as an intermediary to handle the I/O?
</questions>

Thanks

Matt Butler
