Re: [Firebird-net-provider] fbstreambackup: free disk space exhausted
Hello,
the database is at the moment on the same pc. When I have mastered the art of
local backup I will move to the remote servers as well.

I'm not sure, but can you check disk space on the remote server where database
is placed?

Hallo,
I try to move from calling gbak as an external tool for backup and use
fbstreambackup instead.
Unfortunatly I get an error message free disk space exhausted, which is
confusing. The disk has enough space to store the backup file. For that reason
I am guessing that there is something wrong with the way I call the backup.
This is the code (in vulcan.net http://vulcan.net ):
// declare variables
LOCAL fsb AS FbStreamingBackup
LOCAL fs AS System.IO.FileStream
// create new backup
fsb := FbStreamingBackup{ sb:ToString() }
fs := System.IO.FileStream{D:\temp\test.gbk, FileMode.Create }
fsb:OutputStream := fs
fsb:Execute() // It fails here
Can please somebody point out what I am missing here? Maybe the filestream is
not correct assign to FbStreamingBackup…
Thanks
Niko

Re: [Firebird-net-provider] fbstreambackup: free disk space exhausted
Hello Jiri, thanks - that explains the message. I will update the FB Servers on the customers site to 2.5.4 over the next weeks/months. Then the feature is ready to go.

Re: [Firebird-net-provider] Migrations
Ok. For now we had such issues: 1. Long names of tables causes foreign key script creation fail with error Name exceeded implementation limitation. This caused by 31 characters limitation to almost anything not only FK. We crutched this with hashing names with base64 convert. Ugly but works. 2. Second it is drop from support databases with pages less than 16384 because of another impl. limitation for max string field length. This breaks creating MigrationHistory table. We didn't fixed this, because started using separate database. But in near future our previous database would also need to have migrations. I think this can be crutched to use blob field only for Model field of this table. 3. Issue with sequence generators. Maybe you remember discussion about this on github. Looks like I've found good place to configurate particular field. It is in OnModelCreating Properties().Configure(x=x.AddAnotation()) for property. There user can specify what sequence behavior does he need or provide custom. Today I tried to add tests for all this to repo but found out that we need to add separate test infrastructure for EF tests. -Original Message- From: Jiří Činčura j...@cincura.net Sent: 8/29/2015 7:29 PM To: For users and developers of the Firebird .NET providers firebird-net-provider@lists.sourceforge.net Subject: Re: [Firebird-net-provider] Migrations Also if you have some feedback you can discuss it here ahead of time.

For me it doesn't make much sense to have it in beta for say 5+ months. -- Mgr.

Re: [Firebird-net-provider] Migrations
1. I've used hashes from names to avoid dictionaries for mapping name-guid. 2. I think it was about Model field. More precise error I'll tell tomorrow when PC will be available. I don't want to constraint page size, because changing page size for existing databases is done only via backup-restore AFAIK. In case of several GB dbs it's not an option. 3. Yes. Default behavior maybe several pre defined and possibility to provide custom. 4. One more issue I remembered. Dbs created with Initial migration and via CreateDatabaseIfNotExists have different underlying scheme in part of names. I think this should be also fixed. -Original Message- From: Jiří Činčura j...@cincura.net Sent: 8/29/2015 10:08 PM To: For users and developers of the Firebird .NET providers firebird-net-provider@lists.sourceforge.net Subject: Re: [Firebird-net-provider] Migrations 1.
