This does not make much sense to me.
If a user has access to a database through code, and the user can develop & run his own code against the database then your security is the problem. PROD databases are not supposed to allow that. Block the user either at the source or at the oracle login.
Try:
1. move the user to another box that cannot access PROD or whatever
2. change tnsnames.ora - stop everyone
3. create two client oracle directory trees. The only difference is the tnsnames.ora in one tree does not allow the DB box/or users you want to block. Set up the problem user in a group, such that he uses the limited directory and cannot see the other. In other words effectively change ORACLE_HOME for him/her.
DBI used to require an ODBC license from oracle. Put the problem user in a group that cannot activate the license file. You can also remove/delete/uninstall the DBI code from the perl install. You can also put the DBI pm files in a directory some users cannot read. So they cannot excute perl DBI.
You know, if you told us what the actaul problem was instead of asking how to implement a really unusual off-the-wall kind of fix, we could help.
I'm sure you know that trying to block DBI acess to oracle from another server pretty much means nobody on the non-db server will be able to use it. You can disable DBI locally, on the remote server, not remotely on the DB server.

DBIx::Class::Storage::DBI::mysql(3) User Contributed Perl Documentation DBIx::Class::Storage::DBI::mysql(3)
NAME
DBIx::Class::Storage::DBI::mysql - Storage::DBI class implementing MySQL specifics
SYNOPSIS
Storage::DBI autodetects the underlying MySQL database, and re-blesses the $storage object into this class.
my $schema = MyApp::Schema->connect( $dsn, $user, $pass, { on_connect_call => 'set_strict_mode' } );
DESCRIPTION
This class implements MySQL specific bits of DBIx::Class::Storage::DBI, like AutoIncrement column support and savepoints. Also it augments
the SQL maker to support the MySQL-specific "STRAIGHT_JOIN" join type, which you can use by specifying "join_type => 'straight'" in the
relationship attributes
It also provides a one-stop on-connect macro "set_strict_mode" which sets session variables such that MySQL behaves more predictably as far
as the SQL standard is concerned.
STORAGE OPTIONS
set_strict_mode
Enables session-wide strict options upon connecting. Equivalent to:
->connect ( ... , {
on_connect_do => [
q|SET SQL_MODE = CONCAT('ANSI,TRADITIONAL,ONLY_FULL_GROUP_BY,', @@sql_mode)|,
q|SET SQL_AUTO_IS_NULL = 0|,
]
});
