Can't use DBI and mod_perl together in Cygwin.

Fri Dec 17 16:30:00 GMT 2004

Here is a more specific description of the DBI error I'm seeing that has 
me checking out the TCP/IP stack:

DBI connect('','uid/pass@(DESCRIPTION=
     (ADDRESS=(PROTOCOL=TCP)(HOST=$host)(PORT=1521))
     (CONNECT_DATA=(SID=$sid)))',...) failed: ORA-12545: Connect failed 
because target host or object does not exist (DBD ERROR: 
OCIServerAttach) at /var/www/htdocs/bin/testperl.pl line 34

dbi status: ORA-12545: Connect failed because target host or object does 
not exist (DBD ERROR: OCIServerAttach)
