That all sounds good. 0E0 is a true value in Perl. It means "zero but true." And undef is a false value. You don't need to test for undef. > Since I changed DBD::Oracle subroutine ping to use 'select 1 from dual', I don't actually understand why you did that. What was wrong with the normal ping? In any case, there's no need to change the Apache::DBI code, even with your "select 1 from dual" test. It returns a true value (0E0) if it succeeds and a false value (undef) if it fails. Did your script succeed in reconnecting after it lost the connection? > I have another request. The Apache::DBI cached a dead database handle for apache version 1.3.42 if startup.pl create a database handle. The apache child processes inherits this dead handle. It doesn't cause application error but it does take memory space. If there is many apache processes, that's not good. Can you please identify and change the code for this problem? Yes, I haven't forgotten about that, but I haven't had time to work on it yet. You can try fixing it yourself by looking at the code in Apache::DBI that checks if the server is starting under apache 1.x. Otherwise, I will eventually get to it. - Perrin
