We are using NHibernate and firebird with C# code. We have a server application that run 24/7. Our problem is that sometimes we get an exception from when starting new transaction: FirebirdSql.Data.FirebirdClient.FbException (0x80004005): Error reading data from the connection. We always dispose the nhibernate session. The problem is that it is not able to recover from this failure unless we set pooling to false(Pooling=false;). This is of course not desirable. I see that there is a bug filed for the ADO.net Provider: http://tracker.firebirdsql.org/browse/DNET-678 Is this the cause, and if so when will this be fixed? Also is there any good ways to work around this problem? -- Jardar Maatje Nortek Data Services AS Brugata 1 0168 Oslo tlf: +47 95184034 |

How to cancel FBbackup/FbRestore service? If I use cancelToken in c# Task I can't cancel service process. As a result, service continue execution in background (with low speed).

Hi *, I'm reading the JDBC-446 now and thinking we might do something similar. The default connection charset of NONE is pretty wrong in most cases. For .NET it might make sense to change to default UTF8, which on the other hand is correct in a lot of cases. And devs can change it if they really know what they are doing. Not sure whether forcing to specify some charset, thus not having default, is good idea in .NET world. -- Mgr. Jiří Činčura Independent IT Specialist |

That is expected, because there can't be any logging when using the streaming backup. The channel that in FbBackup is used to get log information is not available, because instead the backup data is sent over that channel.

The snapshot build on firebirdsql.org is older than the tracker case. So the fix is presumably not in there. I could get the master from Github but the recent commit history doesn't look like CORE-5307 has been fixed (at least it's not stated directly). -----Ursprüngliche Nachricht----- Von: Thomas Steinmaurer [mailto:ts...@ib...] Gesendet: Donnerstag, 4.

I recently switched from an older provider version (2.x something) to the current 5.0.5.0 build and use it in an embedded scenario. In that process I also switched from FB 2.5 to 3.0 I have stability problems when the system gets under heavy load with concurrent transactions/connections. I receive 335544332 errors (invalid transaction handle) from random locations. Any pointers at what to look? Typical stacks look like FirebirdSql.Data.Common.IscException: invalid transaction handle (expecting explicit transaction start) at FirebirdSql.Data.Client.Native.FesDatabase.ProcessStatusVector(IntPtr[] statusVector) at FirebirdSql.Data.Client.Native.FesStatement.Prepare(String commandText) at FirebirdSql.Data.FirebirdClient.FbCommand.Prepare(Boolean returnsSet) at FirebirdSql.Data.FirebirdClient.FbCommand.ExecuteCommand(CommandBehavior behavior, Boolean returnsSet) at FirebirdSql.Data.FirebirdClient.FbCommand.ExecuteScalar() or FirebirdSql.Data.Common.IscException: invalid transaction handle (expecting explicit transaction start) at FirebirdSql.Data.Client.Native.FesDatabase.ProcessStatusVector(IntPtr[] statusVector) at FirebirdSql.Data.Client.Native.FesTransaction.Commit() at FirebirdSql.Data.FirebirdClient.FbTransaction.Commit() or FirebirdSql.Data.Common.IscException: invalid transaction handle (expecting explicit transaction start) at FirebirdSql.Data.Client.Native.FesDatabase.ProcessStatusVector(IntPtr[] statusVector) at FirebirdSql.Data.Client.Native.FesStatement.Prepare(String commandText) at FirebirdSql.Data.FirebirdClient.FbCommand.Prepare(Boolean returnsSet) at FirebirdSql.Data.FirebirdClient.FbCommand.ExecuteCommand(CommandBehavior behavior, Boolean returnsSet) at FirebirdSql.Data.FirebirdClient.FbCommand.ExecuteScalar() |

I would still like to see a shim and as one default implementation you could use SharpZibLib. Von: Jiří Činčura [mailto:ji...@ci...] Gesendet: Freitag, 29. Juli 2016 15:05 An: fir...@li...
