Re: [Firebird-net-provider] using fb 2.5 and 3.0 embedded concurrently
I changed my backup/restore routine and used gbak instead of the FBRestore
class. That helps no more shutdowns now.
There seems to be something wrong with FBRestore. Calling the class is pretty
straight. So I don't see a ~usage~ error of that class.
FbRestore restore = new FbRestore();
restore.BackupFiles.Add(new FbBackupFile(fromPath));
restore.ConnectionString = connectionString;
restore.Options = FbRestoreFlags.Create;
restore.PageSize = 4096;
restore.Verbose = true;
restore.ServiceOutput += delegate(object sender, ServiceOutputEventArgs e) {
callback(e.Message); };
restore.Execute();

Checked. No dangling connections in the transaction pool after backup restore.
Then when the ~connection shutdown~ error state is reached only 3.0 connections
are in the pool.
If i wasn't clear I can't create any connection in that state. Not even create
a new Database and connect to that. Any connection will throw a ~connection
shutdown~ Exception after that state is reached.
It is not dependent to a certain database. Feels more like the hole embedded
Firebird client is in a shutdown state then :(

I call FbConnection.ClearPool before backup. So there shouldn't be any 2.5
connections to that database still hanging around.
The backup restore I do is inplace. I have replaced the fdb database in its
original location (2.5 before a 3.0 version afterwards). I assume if I had
2.5er connections still in the pool that won't be allowed since there would be
open handles to the database and I couldn't replace the file then?
I will check if clearing the pool when I'm running into the ~ connection
shutdown~ error state helps. But I doubt that this problem has something to do
with the connection pool.

Are you sure. Isn't just cleaning the pool for that connection enough?

Re: [Firebird-net-provider] using fb 2.5 and 3.0 embedded concurrently
Hi, it looked good at first. But I have a problem when upgrading a database from 2.5 to 3.0 in the process. Means I first open the database with the 2.5 client then do a backup/restore cycle via the FbBackup/FBRestore classes (Backup with the 2.5 fbembed.dll in the connectionstring, restore with the 3.0 fbembed.dll). I can then use the database for, looks like, 60 seconds. After that I get an IscException (connection shutdown, error code 335544528) for any 3.0 database currently used in that process. To get that fixed I need to restart the process. Anything in the provider or firebird itself with a 60 seconds timing? -Ursprüngliche Nachricht- Von: Ralf Jansen [mailto:ralf.jan...@mailstore.com] Gesendet: Mittwoch, 22.
