[firebird-support] Re: XE4, Interbase Express, 32/64bit, Firebird 2.5.2
I'm aware of that. We're using Firebird (since 1.5.0 up to the latest 2.5.2) + IBX (Delphi 7) without problems. Currenty I'm testing XE4 with the latest IBX. My first tests are working with no problem both on x32 and x64. So maybe its officially not supported.

Yep, /TASKS=SuperClassicTask was the answer, it works. :) Thank You! --- In firebird-support@yahoogroups.com, Thomas Steinmaurer ts@... wrote: I'm updating an installer made with Inno Setup. Current version is installing CS : /COMPONENTS=ServerComponent,ServerComponent\ClassicServerComponent,DevAdminComponent,ClientComponent'; I want to change it to SC. What sould I change in the firebird install parameters? The executable file (fb_inet_server.exe) is the same for both, Classic and SuperClassic. The visual installer offers a checkbox to run SuperClassic, which is according to the inno setup project file implemented as a task called SuperClassicTask. So you could try to add the following part to your inno setup call: /TASKS=SuperClassicTask or if you are already using /TASKS with other entries, simply add SuperClassicTask to the comma separated list. I'm not sure if this works, but it's worth for a test. -- With regards, Thomas Steinmaurer (^TS^) Firebird Technology Evangelist http://www.upscene.com/ Do you care about the future of Firebird?

[firebird-support] Re: Slow Commit
Hi! Maybe this is your case : Forced Writes Performance impact on #Ubuntu with ext4 no barrier http://www.firebirdnews.org/?p=6421 --- In firebird-support@yahoogroups.com, aalliana aalliana@... wrote: Hello, I'm trying to upgrade a box running ubuntu + firebird that has been running for a while. The old box has Ubuntu 8.04 + firebird 2.1.1 SS running on dual core hardware. The new box has Ubuntu 10.04 + firebird 2.1.4 SS running on a 8 core hareware. I undestand that there are too many variables involved, but is hard to maintain all systems the same to perform the tests. After performing many tests using a profiler, I arrived to the conclusion that the commits take a lot longer on the new hardware configuration. Everything is running faster but commiting takes longer. The hard disk hardware is better, a 7200 RMP SATA drive. Does anybody have any suggestions? PS: On the new hardware, I first installed firebird 2.1.4 Classic, because of lousy performance I changed it to SS. Thanks in advance.

hi,
i have a firebird superserver v2.5.1 on win32, and a table with several
varchar columns of different sizes. for instance,
insert into INTERES (ianrede, itelefon) values ('1234567890',
'123456789012345678901234567890')
where ianrede is a varchar(10) and itelefon is a varchar(30) works as
expected. The database is utf-8, don't know if this is related. Now the
problem:
insert into INTERES (ianrede, itelefon) values ('12345678901',
'123456789012345678901234567890')
gives a 'arithmetic overflow...' error, again just like expected.
BUT
insert into INTERES (ianrede, itelefon) values ('1234567890',
'1234567890123456789012345678901')
works! The entry ist created, and contains 31 characters in a varchar(30)
row. (This results in an exception later on in a delphi component).
Only
insert into INTERES (ianrede, itelefon) values ('1234567890',
'12345678901234567890123456789012')
gives a 'arithmetic overflow...' error just like the sql statement with the
31 chars should do already.
Is this a known problem/bug?

[firebird-support] UDF memory allocation for result string in Linux
Hi!
When I run my UDF (udf_op), I get an error : Bad written UDF detected: pointer
returned in FREE_IT function was not allocated by ib_util_malloc
I use ib_util_malloc in my Win version, no problem there. What should I use in
Linux version? Currently memory allocated with malloc.
SQL:
DECLARE EXTERNAL FUNCTION UDF_OP
RETURNS CSTRING(10) FREE_IT
ENTRY_POINT 'udf_op' MODULE_NAME 'UDF3s';
C:
char * udf_op();
char * udf_op()
{
char *buffer = (char *)malloc(10);
strncpy(buffer, Linux, 6);
return buffer;
}
C compiled with :
gcc -c -O -fpic UDF3s.c
ld -G UDF3s.o -lm -lc -o UDF3s.so
Thank You!
[firebird-support] Re: UDF memory allocation for result string in Linux
I've already have an x86 (LI-V2.5.1.26351 Firebird 2.5 Firebird/linux Intel on port 52), and an x86_64 (LI-V2.5.2.26415 Firebird 2.5 Firebird/linux AMD64 on port 50) Firebird already running paralell. Tried as you said, but no luck (see my prev. reply). :( Guess I have to install an x32 Linux on a VM.

How I compile to get x32? -m32 option gives me a bunch of errors : You need i686 version of Firebird (to get 32-bit libfb_util.so) and 32-bit compatibility development libraries in your Linux distribution (so-called ia32-libs). The simpliest way is probably a parallel 32-bit Linux distribution (maybe in a virtual machine?) with 32-bit Firebird installed. Otherwise, it would be better to have some experience (or someone experienced ;) ) with cross-compiling from x86_64 to x86. A general hint: install 32-bit Firebird in a different location, use -L/firebird-32-location/lib and -m32 when compiling for x86, and -L/firebird-64-location/lib when compiling for x86_64. regards Tomasz -- __--==--__ __--== Tomasz Tyrakowski==--__ __--==SOL-SYSTEM==--__ __--== http://www.sol-system.pl ==--__ __--==--__

[firebird-support] rdb$procedure_parameters non index read
Hi! I'm analysing my stored procedure run with IBExpert, and I can't figure out what can cause rdb$procedure_parameters non index reads. facts : - procedure do not read rdb$procedure_parameters directly - procedure creates and alters procedures, view, triggers (via execute statement in autonomous transaction) It looks like, that firebird inner engine does something wrong, and do not user index (missing index or wrong select?). Any idea? Thank You!
