[firebird-support] How safe is the restart of Firebird 3.0 Windows service/Nix daemon?
Hi! Sometimes I need to alter procedures on running Firebird 3.0 database and I need to disconnect all the users for doing that (there is 'procedure in use' control exception, there is no similar control for triggers). Sometimes I have no other option than to restart Firebird Windows service/Nix daemon and then run alter procedure script. So - my question is - how safe is the usual restart of Windows service/Nix daemon? Can I rely that Firebird gracefully makes all the pending writes to the disk, releases all the necesary resources and (the most important part of my quetion) that the restart can not lead to the gds inconsistency check errors?
[firebird-support] Re: How safe is the restart of Firebird 3.0 Windows service/Nix daemon?
Especially - what happens to the SQL (especially update) commands that are running during the restart of the service? I know that service is not waiting for the completion of those commands. I fear that some interrupted commands can introduce gds corruption errors, that is my greated concern in the case of routine use of service restart.

If it is not enough, use database shutdown with force disconnect of ordinary users. In both cases there is no need to restart server. -- WBR, SD. ++ Visit http://www.firebirdsql.org and click the Documentation item on the main (top) menu.

[firebird-support] Possible problem garbage collector in 32bit 2.5.8
I have a few customers still working on XP with Firebird 2.5.8 32 bit. And it seems that a problem is introduced in 2.5.7 or 2.5.8. In semi regular periods, the Firebird server hangs (hogs CPU). This reappears after a restart of the Firebird server and accessing the database again. Only solution is making a backup, without Garbage collection, and restore. I can deliver databases with the problem for reproduction.

[firebird-support] Re: Possible problem garbage collector in 32bit 2.5.8
I tested a few problematic databases with gfix: Number of record level errors : 1 Number of database page errors : 374 Number of record level errors : 2 Number of database page errors : 67 Number of record level errors : 2 Because some customers have a bad habit when switching of computers, I register abnormal termination of my program. I can also detect power failures etc with this feature. But it seems normal.

I tested a few databases with gfix: Number of record level errors : 1 Number of database page errors : 374 Number of record level errors : 2 Number of database page errors : 67 Number of record level errors : 2 So there are problems in the database. I have added a feature in my software for the usage and termination registration. It seems al normal. So no bad behaviour or power failures. Maybe it is the hardware. But suddenly a large increase of problems with a few different customers puts my suspicion also on the latest Firebird 2.5.8 self.

[firebird-support] Re: Possible problem garbage collector in 32bit 2.5.8
Yes, I have shutdown Firebird (via Services) and copied the FDB file. After restart of the Firebird service and restart of my own program, Firebird "hangs" again. I took the FDB file to my own computer (Firebird 2.5.8 64 bit) and did run gstat on it.
