DESCRIPTION

SYNOPSIS

my $dbiHydra = Bio::Das::ProServer::SourceHydra::dbi->new();

SUBROUTINES/METHODS

sources : DBI sources

Effectively returns the results of a SHOW TABLES LIKE '$basename%'
query. In Oracle I guess this would need changing to table_name from
all_tables where like '$basename%' or something.

my @sources = $dbihydra->sources();

$basename comes from $self->config->{'basename'};

This routine caches results for $CACHE_TIMEOUT as show tables can be
slow for a few thousand sources.

last_modified : machine time of last data change

Gets the most recent update time for any of the hydra's tables.
Only knows how to do this for MySQL databases.

my $unixtime = $dbihydra->last_modified();

DIAGNOSTICS

Run ProServer with the -debug flag.

transport = dbi
basename  = hydra              # dbi: basename for db tables containing servable data
dbname    = proserver
dbhost    = mysql.example.com
dbuser    = proserverro
