able to run (more or less) a full IB6.5 & IB7 install from CD... I'd have
to dig into the code, it gets messy and hairy, but so far it has infact
The gross summary of what needs to be done:
1) DB itself needs to be marked read-only
2) Environment Variables for Temp Spaces and what not need to be set to an
R/W area (in our case we sent them to where ever TEMP environment pointed)
3) IB's User Database (isc4.gdb) had to be copied to TEMP as well
4) Needed to store any existing IB install's registry Information,
over-write it with our temporary server's information, then restore no
matter what (program exited it normally or severe failure)
5) Run IBServer as an application, checking to see if it was first running,
and if it was running if it was an appropriate version (had to support RO
gdb files), etc
