DBI->trace(...) might help. You should also review the docs on the use of errstr. You should be using $DBI::errstr, not DBI->errstr to the best of my knowledge and according to the docs.
Eric D. Berg IPRS Infrastructure From: dbenti...@gmail.com [mailto:dbenti...@gmail.com] On Behalf Of Dan Bent Sent: Wednesday, June 26, 2013 4:15 AM To: dbi-users@perl.org Subject: "connect" not connecting I have been using DBI for several years, and have a fairly extensive group of programs that relay on DBI to connect to a database and extract data. All my programs use a common library of functions that includes a function which connects to the database: $dsn = 'dbi:ODBC:prod1' ; $user = 'user' ; $passwd = 'XXXXXXXX' ; $dbh = DBI->connect($dsn, $user, $passwd, {RaiseError => 1, AutoCommit => 0}) or die "Could not connect to database: " . DBI->errstr ; This has worked for years, but yesterday, it suddenly stopped working. Now my programs get to this function, and stop. No error messages are generated, and the database logs do not show a connection attempt, failed or otherwise. The database itself is an odd thing that I don't expect folks to be familiar with. We use Relativity, which allows CISAM flat files to be used like a relational database. There have not been recent changes to Relativity, and I can see that other (non-Perl) applications are accessing the database without any issues. So the problem seems to be isolated to Perl programs attempting to connect to this database. I am not sure what to do to gather more information about this issue. I wrote s test program to isolate the DBI->connect method, and gather information. I am able to list the available drivers: Proxy, Sponge, DBM, ExampleP, File, ODBC, but I'm not sure what else I can do. I would appreciate any suggestions about how to gather more information or resolve this issue. _______________________________________________ This message is for information purposes only, it is not a recommendation, advice, offer or solicitation to buy or sell a product or service nor an official confirmation of any transaction.
