Subject Re: [IBDI] GDB file physical description
I don't have that documentation but I recently faced that problem
while filling a GDB with the contents of a DBF. There's a physical
limitation of 2Gb per file and if you reach it Interbase doesn't report
anything, it just behaves oddly. I mean, I couldn't make changes
like adding constraints, but I still could query the database. (?)
As you say, I couldn't apply the gfix neither (it got connected but
hung up). I had to backup and restore with the multiple files option,
slicing the database in 4 chunks of 1Gb (just to be safe, I expected
3 Gb of data).
Hope this helps you in some way.
