Perl + DBI + DBD::Oracle

What is the advantages of building a dynamicaly linked version of DBD::Oracle over a staticaly one ?

Thank you.

Re: Perl + DBI + DBD::Oracle

1. Startup speed
2. Resource use (if more processes start, they share the code)
3. Size of your modules

Re: Perl + DBI + DBD::Oracle

How can you tell that DBD::Oracle is dynamicaly linked ?

Re: Perl + DBI + DBD::Oracle

It should not be questioned, since it's the default.

What's the size of Oracle.sl in your install tree? My DBD-Oracle-1.16 for 9.2 is 4.9 Mb on HP-UX 11.00 with perl-5.8.5-dor

find it (.../perl5/5.8.5/PA-RISC-2.0/auto/DBD/Oracle/Oracle.sl), and do

# chatr Oracle.sl

and/or

# ldd Oracle.sl

if the chatr line has entries like

dynamic /your/path/to/oracle/v8170/lib/libclntsh.sl

and a few more, it is dynamic
