Hi,
I have old applications that use DBISAM 4.27 and that share data with a new
application in Delphi XE2 that use DBISAM 4.32.
There is a warning from Elevate on mix old release 4.27 and 4.28 and newest
on BLOB truncate problems.
For solve this, can I install  DBISAM 4.27 on Delphi XE2 for blob
compatibility? Or there is a compatibility option in DBISAM 4.32?
Thanks in advance!

Stefano Monterisi

If you have the source you can try compiling it if you don't then you can't use it since the dcu/bpl files will be incompatible.

Hi Roy,
yes, I have the source...
You think is only a buil packages and libraries....or there is code to
change?
Thanks in advance!

No idea. Tim will have to answer that - try it and see.

Stefano,

These are peer supported NGs and while Tim does occasionally read them
best way to contact him is thru the support email : support@elevatesoft.com

As to your question there are no compatibility modes in either 4.27 to
support newer blob mode or 4.28+ to support older blob mode. Your best
bet is to upgrade both or not use XE for newer app.

As others have said 4.27 might compile under xe2 but there have been
number of fixes since 4.27 to address XE2 compatibility (some are 64 bit
related but number are not) so at best you'd have an install that might
have problems already are already solved in newer builds.

How is the data sharing taking place? The blob issue would only affect
you once the newer version of the  app opens the older tables - if
sharing is one way only (old to new) then you might be in the clear.
Also if you're using dbsrvr then you might be able to work around this
since only dbsrvr accesses data there is no blob issues (of course there
might be some client side changes but those are easy to test - running
older client against newer dbsrvr or vice versa).

Hi Raul,
thanks for help...
You think that I upgrade older applications (4.27) to 4.32 I have solved my
problems?  I can open old files and upgrade them to 4.32 without problems
(in pratice all application open old files and save them with 4.32) ?
Thanks in advance!
Stefano

Stefano,

If you are able to upgrade the old app to use the 4.32 then yes that
would resolve your blob issues as well as XE2 support.

The blob change meant that you cannot mix old and new versions of DBISAM
accessing same tables - so for example if you open and modify the tables
with app that is using dbisam 4.32 then you should not access them again
with 4.27 app.  Upgrading both to 4.32 allows you to safely access same
database files from both apps.
