[firebird-support] Re: How to access Firebird DB on NAS storage device from client workstations
Hello, so if I see it right, it's possible to run a firebird server on a NAS with Linus as OS, have the database on that NAS as well and access it from client workstations, right? Is there a HowTo / a tutorial about such a setup? I have no idea about Linux, unfortunatelly, and so no experience with this. Some customers do ask about such a setup, so I wanted to see if it's possible, what requirements my application has to meet, what steps have to be done to setup Firebird on a NAS / on Linux in general etc. All tipps and advices are welcome. Best regards, Patrick --- In firebird-support@yahoogroups.com, Kjell Rilbe wrote: mariofb123 skriver: Thank you Lester. Based on your reply, I assume that it is not possible to run the Firebird server on the NAS drive, to control the database files located on that drive ? Seems to me you still haven't got this question answered. 1. It is not viable to have the DB file on the NAS and have multiple FB processes access it from variaous workstations. This is not what Marius asks about above, and he has stated that he undrestands that this doen't work. 2. It is not recommended to have the DB file and the server process on two different machines. If this is still going to be done, make sure only one single FB process is connected (has the file open) at any one time. Again, this is not what Marius asks about above. 3. Marius asks about the option to have both the DB file and the FB process(es) on the NAS. Some NAS devices have a Linux distro as OS and allows custom software to be installed directly on the NAS. This is what he wants to do. Noone seems to have answered this. I can't say anything else than I guess it's up to the NAS what it allows and how. From the FB point of view I can't see that there would be a problem with it. So, Mario, maybe you should contact the NAS supplier rather than asking here. What you need is to know how to install FB on the NAS and how to get the NAS to allow connection via port 3050 or whatever you set it up to use. Good luck!

Maybe an old Interbase lib could connect to a modern FB server. Doubt fbembed would be possible, for starters I think it uses modern C++ stuff that old win16 targeted compilers wouldn't support[0]. Worse, it'd be written to assume larger memory ranges than win16 could offer. Scott [0] I think it's something like Visual C++ 4 was the last to target 16-bit.

It seems to me it should be possible to access a firebird server from windows 3.11. We accessed Interbase with windows 3.11 and the connection for at least version 2.0, 2.1 and 2.5 of firebird is about the same. If you can find an old copy of Delphi version 1, 2 or 3 you could write something that accesses firebird. However, it would be difficult to write something in much else since the support libraries would not exist for windows 3.11. Though firebird will not compile on windows 3.11 because of lack of support libraries. Of course the question Mark asked is still relevant, why would you want to access from windows 3.11? Though I admit after much research I succeeded in getting windows 98 and older versions of programs running on a relatively new computer. It was sooo fast it was almost beyond belief. However, many web sites complained about the old browser. Ted

[firebird-support] Rolling back from 2.5 to 2.0
Hi all, I work with proprietary software that interfaces with Firebird 2.0. I recently updated to 2.5, but found that some features of our software had stopped working. Unfortunately, when I tried to roll back my test machine (Win7x64) to 2.0, the features of software that broke with 2.5 remain broken. I've performed a complete uninstall (including the registry), the directory has been deleted, but the software still acts like it did when 2.5 was installed. Does anyone know what might be persisting from the update? Thanks for your time.
[firebird-support] Re: ASCII_VAL for BLOB
I found out that typecasting as a text blob was the solution: ASCII_VAL(CAST(SUBSTRING(Image FROM 1 FOR 1) AS BLOB SUB_TYPE TEXT)) Note typecasting as (VAR)CHAR(1) or CHAR(1) CHARACTER SET ASCII does *not* work. According to the Firebird documentation, ASCII_VAL is only supported for (VAR)CHAR and text blobs, still i think it is better that also the right value should be returned for a byte in a binary blob, or that a 'not supported' error is raised.

Thanks, that was very informative! I'll try to include more information to better explain my situation. Our software uses SQL scripts to create databases that we can then interface with. After installing 2.5 I can access and modify existing databases. If I roll back to 2.0, I can still access and modify those same databases, but the script to *create* a database no longer works and instead throws an ISC error (335544375). Since it works in machines running a virgin 2.0 install, but not on 2.5 or a machine that has been rolled back from 2.5, which suggests to me that the uninstaller is missing something.

That exception is Unavailable database. What that means in the context you describe is that the sql CREATE DATABASE has probably gotten as far as creating a file in the filesystem with the basic infrastructure for making it into a database; but something is preventing the server from connecting the client app (isql? calls in a batch script?) to it. If it can't do that, then no database. Database unavailable can occur for several reasons, not all of them related to one another. If the server is not running, or if the script is not supplying the correct security info (user name password), or the client's connection to the server got dropped (or crashed); if (in 2.0) your script is trying to make a serverless connection to a Classic server; you (or the script) tried to create the database on a non-physical disk or partition (a Windows share, for example)...and so the list goes on. Since it works in machines running a virgin 2.0 install, but not on 2.5 or a machine that has been rolled back from 2.5, which suggests to me that the uninstaller is missing something. The uninstaller uninstalls what its installer installed, on the whole. Be very, very careful to back up components of the server that were customised for your application package, such as the security database, aliases.conf and possibly firebird.conf. AFAIR, the uninstaller does leave these behind; but I think you said you deleted those. You said originally that you had installed Fb 2.5 on Win7 X64. However, if you installed the 64-bit Firebird and instructed the installer to install fbclient.dll into the system directory on 64-bit Windows, then it will be the 64-bit client library, which the installer may have been unable to delete because it was loaded. Your app is probably 32-bit and, if you are trying to run it locally, it's possibly not finding the 32-bit library of the same name. It could be worth checking. Let me know if there is any additional information I can provide that would further explain my situation. IBPhoenix does installation assistance as a professional service. IBP pays me (and others) to do this stuff for its paying customers. I'd better bow out here, lest I find myself in hot water with my principals.
