[firebird-support] Unavailable database error when running gbak from my apllication
Greetings colleagues! I need to programmatically create Firebird 1.5 db backup file within an app written on C++.NET. Problem is that when I run gbak using System.Diagnostics.Process class, it throws message gbak: ERROR: unavailable database. Parameters string looks like this:-b -se localhost:service_mgr localhost:Ñ:\\DB\\mol.GDB C:\\DB\\molbk.fbk -user sysdba -pass masterkey Thing is that when I run gbak from console (with the same rights as my app) with exactly the same parameters it works well. So the problem seems not to be with access rights. Any ideas on this? [Non-text portions of this message have been removed]

[firebird-support] unavailable database
In case somebody's just reading by and has a clue, don't hold back :-) For the first time since working with Firebird I'm probably about losing data. Here's what I did to successfully break my precious: - shutdown -f while 1 one user who told he's not working was in fact still working with the database - starting a backup which was expected to run some 7 minutes - terminated the process after some 30 minutes (no CPU usage of gBak.exe for more than 20 minutes) Now an ODBC connection test works fine. Connecting via Jiri's .net provider times out (CPU 50% for 2++ minutes) Connecting via IBExpert times out (CPU 50% for 2++ minutes) From 6 databases on that server, only 1 is making trouble. I made a file copy of the offending file to C:\Current.fdb. gfix -v -n C:\Current.fdb results in unavailable database (userpw supplied...) gfix -v -n localhost:C:\Current.fdb results in a new child process fb_inet_server.exe at 50% for a short time (~2 seconds), a new blank line in the command window. gbak -b -v C:\Current.fdb C:\Current.fbk results in unavailable database gbak -b -v localhost:C:\Current.fdb C:\Current.fbk a new process gbak.exe with constantly 0%, a new file C:\Current.fbk with 0 bytes, a new child process fb_inet_server.exe at 50% for a loong time, some update to the database, because c:\current.fdb gets a new file-timestamp. ouput says: readied database... creating file ... starting transaction nothing more happens. How would I best go about trying to fix this? I have a good backup which is 4 hours old. There are worse things in the world than having to revert back to that, but if possible I'd try to restore this one.

Re: [firebird-support] unavailable database
How would I best go about trying to fix this? I forgot some things: - of course I brought the database online again after backup first failed. - users are logging in with explicit usernames and roles. nobody and no software is using SYSDBA besides me - database only has 1 file (no limbo problems) gfix -v -full reports Number of record level errors:1 so does gfix -m ... , gfix -m -i ..., gfix -m -full -i ... after executing all possible combinations of gfix -m, gfix -v still reports Number of record level errors: 1, and gbak -b -g -i -v ... still does not get over starting transaction. ++ Visit http://www.firebirdsql.org and click the Resources item on the main (top) menu.

Re: [firebird-support] unavailable database
Oh, I expressed that wrong, I think. What I really meant was (so, no problems with distributed files) and also non with limbo transactions. I am not using shadows nor 2-phase transactions.

Re: [firebird-support] unavailable database
after executing all possible combinations of gfix -m, gfix -v still reports Number of record level errors: 1, and gbak -b -g -i -v ... still does not get over starting transaction. I don't have any idea what happened, but suddenly the backup *did* work. This completely toils my understanding of why - after a clean reboot of the server and all users disconnected - a command would at first not work, but then suddenly would when just trying often enough. So, I made a backup, restored that to a new database, and this one seems to work so far. I hope there are no hidden surprises. ++ Visit http://www.firebirdsql.org and click the Resources item on the main (top) menu. Try Knowledgebase and FAQ links !

Limbo transactions are the result of an incomplete two phase commit and have nothing to do with multi-file or even shadowed databases. The application has to initiate a two phase commit with a call to PREPARE. Normally that's done to coordinate updates in different databases, but it can also be done to coordinate a database commit with some other activity that does not have the ability to rollback. Good luck, Ann [Non-text portions of this message have been removed]

When a database is broken, the first thing to try to make a back-up is to use -g option, to avoid garbage collection, sometimes the problems resides on versions that are not needed to complete the back-up. see you ! ++ Visit http://www.firebirdsql.org and click the Resources item on the main (top) menu.

[firebird-support] Unavailable database
FB1.5.6.5026/w32 Win7 x64/sp1 When I began my transition from Win2k to Win7 x64, I couldn't get any of my apps which ran an fb db to run: it was always unavailable database or from a Delphi message box, check that the database is present. Drove me mad. Then I started changing Win7 user permissions, and finally everything worked again. Recently I've been having windows problems with dbl-clk not opening pdf and rtf files. So I ran Windows Folder and File fix applet and it didn't find anything. Shortly after I shut down. This AM all of my fb apps returned unavailable database or the equivalent from a delphi app. I mainly use IBO_SQL to do my testing: that's what gives the unavailable database -904 335544375 error. I uninstalled and reinstalled twice. Same thing. So I started looking at my db permissions and they had been reduced. So I gave them full permissions, but I still can't get anything to open. Running this, however, appears to work: isql 'C:\Program Files (x86)\Firebird_1_5\examples\employee.fdb -user SYSDBA -password masterkey CON That is, if I can presume that the 'CON' return means that fb connected to the db. I'm logged in as an administrative user. employee.fdb lists full control for SYSTEM and Administrators(MyComputer\Administrators) Only 'Read Execute and Read' for (Users\MyComputer\Users) Any suggestions?
