    DBD::Oracle

    Hey folks,

    On our test server (Solaris 10) we have numerous test and train databases at 10g.

    We now have an 11g database set up on the server aswell.

    Does anyone have any experience with perl DBI (DBD::Oracle)?

    Some of our test interface scripts are not running on this new 11g database with problems at the DBI connect part of the script. I have written a little test connect script to try and get working

    Code:
    #!/usr/local/bin/perl -w
    
    #use  strict;
    
    use DBI;
    
    
    
    
    open(OUTP,">test_out.txt") || die("Could not open the test file\n");
    
    my $dbh = DBI->connect("DBI:Oracle:testdb","user", "pass")
      or die "error occured   $DBI::errstr\n";
    
    $sql = "select table_name from user_tables  ";
       $sth = $dbh->prepare( $sql );
        $sth->execute or die "Can't execute SQL Statement: $DBI::errstr\n";
    
       while ( @row = $sth->fetchrow_array() ) {
          print OUTP "@row\n";
      }
    
    
    #   $sth->finish;
       $dbh->disconnect();
       print "Disconnected from Oracle\n";
    
    
    exit;
    I can successfully run this against my 10g test database but get errors trying to run against 11g train database.

    Error as follows

    DBI connect('mydb','user',...) failed: ERROR OCIEnvNlsCreate. Check ORACLE_HOME env var, NLS settings, permissions, etc. at ./dbconnectIFSTEST.pl line 12
    error occured ERROR OCIEnvNlsCreate. Check ORACLE_HOME env var, NLS settings, permissions, etc.

    Do i have to reinstall DBD::Oracle within my 11g environment to get it to work?
    Could this affect the numerous other test systems on this server that are using perl to connect to their oracle databases?

    Thanks
    Phil

    Wild guess... are you pointing to the right ORACLE_HOME?

    Can you connect sqlplus using the same environmentals?

    Yeah, sqlplus works fine, just using perl dbi.

    I am assuming i have to install DBD::Oracle against this database. I am confused as to how many DBD::Oracle drivers you can have. I was thinking you just had one in your perl installation that would connect to all your databases but perhaps this is not the case.

    Path

    in your PATH for 10g you are pointing to you ORACLE 10g bin , lib and lib32. You are not pointing to all of those things in your 11g PATH

    may be you can use 'truss' command and see where the script is failing.

    See Jeff's notes on 'truss' ing
