Re: [firebird-support] Compatibility questions: Current release versus 1.5.3.4870
Hi ! It's dificult to tell... From version to version there is minor problens that can occur, like new reserved wirds and so on. But in general, you will be safe doing the upgrade. It's recommend to perform a back-up/restore cycle to upgrade de database ODS. But FB 2.5 can read databases created by 1.5 version. You have a problem, in the actual state, it's not working, what can you lost if you try to upgrade and discover that it will not work ? Make a copy of the database and give it a try, it will not hurt. good luck ! Em 26/7/2017 12:52, scott...@comcast.net [firebird-support] escreveu: Hello!

Re: [firebird-support] Enable authorization for legacy Firebird clients
HI Em 7/7/2016 05:49, tomi.j...@oscar.fi [firebird-support] escreveu: Hi, I don’t know if i have understand “Enable authorization for legacy Firebird clients” right but.. I just installed Firebird 3 to new development server and checked “Enable authorization for legacy Firebird clients” so I can test connection from old 2.5 clients. In this installation window I create random password like “pass1234”. When I connected to database from same server connection is okay with “pass1234”. But when I tried to connect from old development server where firebird 2.5 is installed with “pass1234” I get error “Your user name and password…”. My surprise was when I tried connect database from old server with pasword “masterkey” that connection is succesfully. I have not created user SYSDBA with “masterke” password and still I get connected in database. So my question is that should this be like this? Best regards, -Tomi I don't know how are your configurations, but to enabled Legacy Auth you must change: AuthServer = Srp, Legacy_Auth UserManager = Srp, Legacy_UserManager WireCrypt = Enabled after that, the server is enabled to authenticate using the old protocol. I think you are in this point, but are unable to authenticate from other users because the other users was create by the default plugin (SRP), you must create those users using the Legacy_UserManager plug in.The SYSDBA was automatically created by the installer using the Legacy_UserManager plugin this is the reason you could connect using SYSDBA. connect to your database and execute the following: select sec$user_name, sec$plugin from sec$users; You should see something like: SEC$USER_NAME SEC$PLUGIN === === User1 Srp User2 Srp This indicates that the users are created but with the new SRP plugin, to authenticate legacy users you need to create them using the legacy user manager plugin. execute this: create user User1 password 'pas1234' using plugin Legacy_AuthManager; commit; after that execute this: select sec$user_name, sec$plugin from sec$users; You shoud see: SEC$USER_NAME SEC$PLUGIN === === User1 Srp User2 Srp User1 Legacy_UserManager Note that you have two entries for User1, one for the SRP plugin and the other for the Legacy Authentication.

[firebird-support] FB 3 - Per database configurations (Providers and Security Database vs Legacy Auth)
Hi !
I am looking at the per-database configuration (FB 3) and have two doubts:
I defined my databases.conf like:
demo_naolocal=c:\bd\demo_naolocal.fdb
{
Providers = Remote,Loopback
}
after that on the same machine I tryed:
C:\fb3>isql demo_naolocal -user teste -password abc
Statement failed, SQLSTATE = 08001
I/O error during "CreateFile (open)" operation for file "demo_naolocal"
-Error while trying to open file
-O sistema não pode encontrar o arquivo especificado. (Translates to:
The system could not find the specified file)
Use CONNECT or CREATE DATABASE to specify a database
SQL> quit;
C:\fb3>isql localhost/3053:demo_naolocal -user teste -password abc
Statement failed, SQLSTATE = 08001
unavailable database
Use CONNECT or CREATE DATABASE to specify a database
SQL>
I expected the first one to fail and the second to succeed.
On the release notes page 18 I found this:
Disable embedded connections
If you don't want any type of direct access, you may disable embedded
mode (= direct filesystem-level
access) altogether by opening firebird.conf and locating the Providers
entry. The default (which is
probably commented out) is:
#Providers = Remote,Engine12,Loopback
Now, either remove the hash mark and the Engine12 provider (this is the
one that makes the embedded
connections), or – better – add an uncommented line:
Providers = Remote,Loopback
The Remote provider takes care of remote connections; the Loopback
provider is responsible for TCP/IP
connections via localhost, as well as (on Windows) WNET/NetBEUI and XNET
connections to databases
on the local machine. All these connection types require full
authentication and have the server process, not
the user process, open the database file.
Please notice that you can also set the Providers parameter on a
per-database basis. You can set a default
in firebird.conf as shown above, and then override it for individual
databases in databases.conf
like this:
bigbase = C:\Databases\Accounting\Biggus.fdb
{
Providers = Engine12,Loopback
}
if I change the databases.conf to:
demo_naolocal=c:\bd\demo_naolocal.fdb
{
Providers = Remote,Loopback,Engine12
}
I can connect with both alternatives.
C:\fb3>isql demo_naolocal -user teste -password abc
Database: demo_naolocal, User: TESTE
SQL> quit;
C:\fb3>isql localhost/3053:demo_naolocal -user teste -password abc
Database: localhost/3053:demo_naolocal, User: TESTE
SQL> quit;
C:\fb3>
What I am doing wrong ?
The second doubt is regarding per-database security vs Legacy User Manager
I have on databases.conf the following entry:
demo_s2=c:\bd\demo_s2.fdb
{
SecurityDatabase = demo_s2
}
SQL> create user t4 password 't4' using plugin legacy_usermanager;
Statement failed, SQLSTATE = 42S02
add record error
-table PLG$VIEW_USERS is not defined
SQL>
I can create SRP users without a problem, my question is:
Is it possible to have legacy users stored on a database distinct from
security3.fdb ? if so... I just need to create the missing view ?
SQL> show view plg$view_users;
PLG$USER_NAME (SEC$USER_NAME) VARCHAR(31) CHARACTER

Sorry if I misunderstood or my knowledge of SP is lacking. I did not read it in full details... But the case of select on views be able to use the index on the first table I believe that's because of using of outer joins, with inner joins that would not be the case... see you ! --- Este email está limpo de vírus e malwares porque a proteção do avast!

Re: [firebird-support] Suboptimal plan
Hi ! There is some tricks to change the way optimizer will choose the order of tables: example: select * from LongTable L left join ShortTable S on (S.FieldA = L.FieldA) The outer join would force the table on the left to be scaned first. Another option is select * from LongTable L join ShortTable S on (S.FieldA = L.FieldA+0) the +0 (or || '' if the field is a char/varchar) would prevent the optimizer to use the index on LongTable.FieldA and could lead to change the join order see you ! Em 1/8/2014 18:09, Aldo Caruso aldo.car...@argencasas.com [firebird-support] escreveu: Sean and Carlos, thanks for your answer. Although the statistics are up to date the optimizer still chooses the shorter stream as the controller. Nevertheless, I found a workaround using a subquery on the shorter table instead of a join. This forced the optimizer to traverse the longer table first and boosts the performance even more than using an optimized query with a fixed plan. Thank you very much for your help.

Carlos Firebird Performance in Detail - http://videos.firebirddevelopersday.com www.firebirdnews.org - www.FireBase.com.br ACacacfs Hello, ACacacfs In a select statement there are two tables joined by a single ACacacfs matching field, with search conditions in both of them.

Re: [firebird-support] How to convert big FIREBIRD DB to one charset (win1251) to UTF8 ?
Em 30/5/2014 04:26, loris.lu...@gmail.com [firebird-support] escreveu: I need your help and/or suggestions to solve a (maybe uncommon) task. I searched a lot on the web and I had some success using a tool called fbclone but this is definitely not a solution (due to extreme slowness of the conversion, many days, something must be wrong with this software) I have a large Firebird 2.5 DB (a couple of tables have few millions records) to convert from WIN1251 charset to UTF8 charset. Is there a way to do efficiently this kind of conversion? (preferably not using a intermediate text sql dump, that would not applicable because the size of the DB). I'm using Firebird on a linux machine, and I really like to do the job using a bash script, but I can fallback also using a remote Windows pc. Thanks for any suggestions. Best regards. I don't know if there is a faster way... But this one would be a secure and very easy way: 1.) Extract metadata from the source database (isql -x) 2.) Change the definition of the domains and/or fields to the desired charset 3.) Create a new database with the corrected script 4.) Use IBDatapump (or any other datapump tool) to transfer the data I don't know the size of your database, but I doubt it will take days to transfer it. To speed up the process, turn forced writes off, try to keep the source/destination database on diferent disks and use local/embedded connection see you !
