Error messages and such

[kschmidt]

Hi,

I have two questions. First, where can I find the possible error
strings that $DBI::errstr might contain? 

Second, when a connection to a database is made via DBI->connect(..),
how long will that connection stay open? Does it matter if the
database is on the same machine or on a separate machine from the DBI
application?

Thanks,
-Kevin
