Hi,
The firebird that I am using is in version: SO-V6.2.796 Firebird 1.0.
I have done a few testing on firebird database and its shadow
(auto/manual mode)features. Here are the test cases, please let me
know whether all the experience that I encoutered is the normal
behaviour for firebird.
case 1:
I have created a shadow for my database. When I remove the primary
database file, my application still managed to update the data to
database without prompting any error. So, user would not know that
the database file has been accidentally removed ?
case 2:
When my database is in force write off, I notice the datbase file
size is increasing and same to shadow file. When I remove the
database file, the size of shadow file is still increasing.
case 3:
for the other case, when I turn on force write, the database and
shadow file size is STATIC (no change) though data is still inserted.
but the timestamp of the files are changed accordingly.
