Im connecting to a database on a remote machine. The node and catalog
command were successfully run. I can connect to the database from the
db2 command line.

db2 => connect to dkt_old user xxx using yyy

  Database Connection Information

Database server        = DB2/LINUX 7.1.0
SQL authorization ID   = DOCKET
Local database alias   = DKT_OLD

I can view and select tables from the remote db.

When I try to connect via DBI it fails

$dbh = DBI->connect("DBI:DB2:dkt_old", <username>, <password>,
                                  { PrintError => 0,
                                    RaiseError => 1,
                                    AutoCommit => 0 } )};

DBI connect('dkt_old','docket',...) failed: [IBM][CLI Driver] SQL1031N
The database directory cannot be found on the indicated file system.
SQLSTATE=58031

I would greatly appreciate any suggestions to the cause of this
problem.

thanks
