Re: ORA-911 during DBD::Oracle prepare

The problem are bind parameters. With DBI, you don't specify bind variables by name, you have to use positional binds. Your statement should read something like this:
my ($usrenv,$ip,$osuser,$mach,$prog,$c1,$c2);

$sth = $dbh->prepare(q{

        DECLARE
        usrenv vachar2(32)  :=?;
        ip  varchar2(17)    :=?;
        osuser varchar2(32) :=?;
        mach varchar2(128)  :=?;
        prog varchar2(128)  :=?;
        c1   varchar2(128)  :=?;
        c2   varchar2(128)  :=?;
        BEGIN
	SELECT machine, program, SYS_CONTEXT(usrenv, ip),SYS_CONTEXT(usrenv, osuser) 
         INTO  mach,prog,c1,c2
 		FROM v$session VS;
        END; ));
#       Now binding parameters.......
        $sth->bind_param_inout(1,\$usrenv,32);
        $sth->bind_param_inout(2,\$ip,17);
        $sth->bind_param_inout(3,\$osuser,17);
        $sth->bind_param_inout(4,\$mach,128);
        $sth->bind_param_inout(5,\$prog,128);
        $sth->bind_param_inout(6,\$c1,128);
        $sth->bind_param_inout(7,\$c1,128);

In other words, the invalid character is ':'.
