Hi!
I have set of Delphi applications that uses IBX and Zeos for connecting to
Firebird 3.0 server. Some are direct client-server solutions (i.e. Delphi
application uses IBX or Zeos components to open connection on the Firebird
server) and some are 3-tier applications which have Delphi server

Sometimes I receive error message (during development and tests, of course):
deadlock
update conflict with concurret update
concurrent transaction number is 2926
Then I can find the other attachment with the long-running transaction using:
select a.mon$user,
We should move the project to the github and use google groups for discussions.
It is obvious, wondering, why such proposal has not emerged so far already.

Sometimes I need to deactive all indices (for some special processing whose
intermediate results can invalidate constraints) and then reactive them all
again. Of course, I can do this with DB restore option which does not activate
indices during restore process. But so far I have always

My client occassionally receives "connection rejected by remote interface"

of versions between gds32.dll/fbclient32.dll and server version can create such
errors, but those are deterministic errors that happens

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

OK, there are multiple error reports in Flamerobin trackers about this and no
solution in more than 1.5 years. Flamerobin 9.2 works as expected, although it
does not support internal functions, but such feature is not necesary for
script execution. Apparently, Flamerobin is ceasing to exist.
It appears, that Delphi XE 10.2 code makes the second call only in the specific
case:
if (fetch_res = isc_bad_stmt_handle) then And that makes the erroneous second
call rare enough to solve the problem in my question. So, the solution is to
replace the initial general condition (fetch_res <>
Maybe someone knows why Jeff introduced such second call and what bugs this
second call tried to solve?

Hi!
My question is the result of the investigation of the database that froze
during backup (as reported in

https://groups.yahoo.com/neo/groups/firebird-support/conversations/topics/131840).

For DB upgrade (from 1.5 to 3.0) I need to define custom internal function like
this:
create or alter function F_ABS (
VAR_1 double precision)
returns integer
AS
declare variable result double precision;
begin
result = abs(var_1);
return result;
end
But I am confused. My
I checked the system again - we use 3.0.2 indeed.
There is no particular reason why we use -mend. We use it routinely between
backup/restore operations to prevent the situation that any corruption errors
my intervene in our operations. My understanding is that mend can not and it
should not
No, we don't use -g.
We are doing immedate restore anyway after each backup. The freeze during
backup time greatly increases time when the system is down and unavailable and
it is becoming unacceptable.
I have experience that such freeze happened once to the database that soon got
corrupted.
Operating system is Windows
Hi!
We have observed, that Firebird 3.0.1 freezes on one specific table for some
10-20 minutes during backup. This freezing happens only in the case when
gfix/mend had been performed before backup. Backup runs smoothly when no
gfix/mend had been performed previously. There are no significat
OK, I guess there is not available better solution than quite risky:
in autonomous transaction do execute statement 'alter table accounts add
balance double precision';
etc.
Hi!
I am using Firebird 3 and I need to write one execute block statement which
makes several alter table and update table commands, like:
execute statement 'alter table accounts add balance double precision'

etc.

Hi!
I am running Firebird 2.1 and I am receiving deadlock error with the
transaction Id. From this Id I can find the attachment with the SQL:
select a.*
from mon$transactions t
left join mon$attachments a on (t.mon$attachment_id=a.mon$attachment_id)
where t.mon$transactionid=2264690
Solution found - I had to use the "create user" command with the "using" clause:
SQL> create user SYSDBA password 'masterkey' using plugin Srp;
My firebird.cong indicated that Legacy_Auth is the first (default) user manager
and it was necessary for isql to know that Srp manager had to be used:
isql allowed to change the password of the SYSDBA account but that did not
removed original error message about "installation incomplete"...
OK - I am starting to understand. Apparently client had Firebird default
instance Windows registry entry from the Firebird installations of the previous
versions. That is why Firebird 3.0 installation wizard did not displayed
extended configuration form with the possibility to initialize
OK, I have working Firebird 3.0.1 installation and I have copied security3.fdb
from the broken Firebird installation and now I am also receiving the error
message. So - security3.fdb is somehow broken, problem is in security3.fdb
Actually, I don't understand this thing about old and new authorization system.
Does it mean that there are two SYSDBA and other user accounts - one for old
and other for new authorization system and does it mean that there are two sets
of passwords?
Is it safe to check 'Enable authorization

Hi!
IBExpert uses two settings for database charsets:
- Charset (apparently Database related) and
- Font Character Set (apparently Client related)
As I understand then Charset is the same setting as lc_ctype=UNICODE_FSS in
TIBDatabase.Params parameters. But how can I indicate Font Character Set
I am sorry, this was false alarm! I used IBExpert and Flamerobin with the
gds32.dll from the previous Firebird versions (not 3.0.x). After updateing
gds32.dll all is working as expected.
Empty body is not the cause of the error message, because:
- in old times the empty body problem was reported as SQL syntax error and the
server remained alive
- the problem happens with the procedures that already were created in Firebird
1.5 and that have large bodies.
This is becoming serious, because datbase has several hundreds procedures and
some of them have the same situation (date arguments and variables) and have
the same problem. Problem manifsts only when free statement is issues. Problem
disappers when the procedure is changes from the IBExpert
Problem happens only on dialect 1 database, dialect 3 database accepts this SQL
as expected.
I am trying to create or modify the following procedure:
create or alter procedure test_procedure(id integer, p_from_date date)

I know that it was necessary to execute ALTER PROCEDURE for the parent

We managed to use Firebird 1.5 and 2.1.7 clients (gds32.dll/fbclient.dll)

OK. After Firebird 64 bit installation it was necessary to make Firebird32 bit
client installation and with Firebird 3.0 32bit fbclient.dll/gds32.dll this
statement can be executed normally.
Are the following statements correct?
- Most Firebird client software still is 32bit (Flamerobin, IBExpert, Delphi
2009 and older editions) and therefore it requires 32bit Firebird 3.0 client
dlls (fbclient.dll or gds32.dll) even if it connects to the 64bit edition of
server.

I have Firebird 2.x database which from time to time has rather long

Hi!
I have different Firebird instances/databases, one is running on Windows,
another on Linux (the servers have different RAM amount as well). The execution
of the same SQL code results in almost the same indexed reads, non-indexed

I managed to find the exact cause (in terms of SQL) of this difference.
I have simple update statement like
update contract set
total=total
where contract_number=5;
When I call this statement 2 times (in the same transaction) on the Windows
server, then the number of reads for the second
Of course, I checked the triggers of this table. There are not any dependencies
or futher updates in them. The size of the table is very modest - less several
thousands of records. It is heavily used - both in selects and updates.
The strangest part of the store is this - such unexpected reads
