The DontDlClose was a suggestion to stop the seg faulting on exit.
When I said you can use DSN=emanuel-sbart;UID=*;PWD=*; I did of course mean to say you need to keep the 'dbi:ODBC' on the front. i.e.
'dbi:ODBC:DSN=emanuel-sbart;UID=*;PWD=*;'
blush :-)
I have fixed that now.
Ok, got one step further.
Now the test program no longer segfaults, but seems to go into an
endless loop, trying to connect WITHOUT UID and password, and it gets snubbed by the Adabas library for that (see sql.log below).
Window Hdl = (nil)
Str In =
[DSN=emanuel-sbart;UID=walter;PWD=***;;UID=;PWD=;][length = 48]It seems, as if additional empty UID and PWD fields contents get tacked at the end of the connection string so that UID and PWD get passed onto the ADABAS-Driver empty. The question now is: what is doing such an ungodly thing ?
Furthermore the programs size grows constantly (memleak).

Martin, thanks.
I checked. my unixodbc is indeed threaded.
The driver library however, is not:
/usr/local/lib/odbclib.so /lib/libNoVersion.so.1 => /lib/libNoVersion.so.1 (0x400a9000) linux-gate.so.1 => (0xffffe000) libsqlrte.so => /usr/local/lib/libsqlrte.so (0x400ce000) libm.so.6 => /lib/tls/libm.so.6 (0x40109000) libc.so.6 => /lib/tls/libc.so.6 (0x4012c000) /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x80000000)
Even with dontDLClose=1 set, I get the dreaded:
Can't connect to data source DSN=emanuel-sbart;UID=*;PWD=*;, no database driver specified and DBI_DSN env var not set at odbc-emanuel-test.pl line 17
message. In particular, do you have any idea how I should interpret the
'no database driver' specified part of the message; is this the result of an earlier failure or does it mean something?

Martin,
thanks for your reply.
as to the version of unixodbc, I use what is part of SuSe 9.2:
Name : unixODBC Relocations: (not relocatable) Version : 2.2.9 Vendor: SUSE LINUX AG, Nuernberg, Germany Release : 4 Build Date: Mo 04 Okt 2004 22:49:44
Is there a way other than recompiling to check whether threading is enabled in this build ?
Try running ldd on libodbc.so and if it mentions pthread library it is probably built with --enable-threads=yes.
Changing the connect string to
my $dbh = DBI->connect('DSN=emanuel-sbart;UID=***;PWD=***;')
|| die "can't connect to $data_source: $DBI::errstr";
as you suggested results in the message:
Can't connect to data source DSN=emanuel-sbart;UID=***;PWD=***;, no database driver specified and DBI_DSN env var not set at odbc-emanuel-test.pl line 17
You asked about the driver I am using:
-----------/etc/unixODBC/odbcinst.ini-------------- [AdabasD] Description = AdabasD -Treiber Driver = /usr/local/lib/odbclib.so
this .so is from the adabas11-06 distribution.
-------------/etc/odbc.ini [emanuel-sbart] Description = Adabas 11.06 on emanuel Driver = AdabasD Server = emanuel Database = sbart
Try adding DontDLClose=1 to your driver entry in the odbcinst.ini file. It stop unixODBC calling dlclose. Sometimes drivers install atexit handlers and once the driver manager has unloaded the .so they are invalid at exit time.

I might be wrong - my info is well out of date... but on Linux, Perl built multithreaded always segfaulted with unixODBC. I think this happened even
if
unixODBC was built threaded (--enable-threads=yes - the default for
unixODBC's
configure but I'd check your unixODBC was built threaded). I can't remember
the
exact reason I'm afraid. isql is not threaded.
The data source not found message may be related to what DBD::ODBC does. It first tries to call SQLDriverConnect with (in your case) emanuel-sbart
and
when that fails calls SQLConnect(emanuel-sbart) - you can see this in your
log.
You can get around this by making the DBI connect string "DSN=emanuel-sbart;UID=db_user;PWD=db_pass;". See
http://www.easysoft.com/products/9999/faq_answer.phtml?ID=97&product=2002
but it won't make the segfault go away. I'd rebuild your Perl without
threads if
I were you.
You can also see from your log that the SQLConnect succeeeds.
BTW, you did not mention which driver you were using.

Hi, all
I am experiencing a puzzling problem while trying to get an DBD::ODBC connection (via unixODBC) working from a client machine A (Suse linux) to a an ADABAS-D-11 database running on a remote machine (B, also Suse linux)
-------------------------- Machine A (client)
Linux 2.6.8-2
Perl : 5.008005 (i586-linux-thread-multi)
OS : linux (2.6.8.1)
DBI : 1.43
DBD::Proxy : install_driver(Proxy) failed: Can't locate RPC/PlClient.pm in @INC
DBD::ODBC : 1.06
----------------------------------------------
Connections using isql (unixODBC) from machine A to machine B run smoothly, hence I reckon, unixodbc and prima facie odbc-configuration blotches are not the problem.
When I try to trivially connect with DBD::ODBC to the very same DSN that I could connect to using isql without a problem, I get a segmentation fault.
----------trivial-connect---------------------- #!/usr/bin/perl use DBI; my $dbh = DBI->connect('dbi:ODBC:emanuel-sbart', '***','***') || die "can't connect to $data_source: $DBI::errstr"; $rc = $dbh->disconnect; exit(); --------------------------------
and inspection of the sql.log (of unixodbc) reveals the error message:
---------------------
Message Text = [[unixODBC][Driver Manager]Data source name not found, and no default driver specified]
[ODBC][13206][SQLError.c][424]
-------------------------------
Can anybody give me an idea which direction could be pursued to solve this problem ?
What beats me is that isql can connect to my remote database, but an dbd::odbc connection to the same DSN utterly fails.
Any hints welcome.
