Perl interpreter supporting both oracle and sybase - oracle

Question

Can some one let me know how to use both sybase functions and oracle functions in same perl script using a perl interpreter supporting both syb and ora modules?
I have 2 perl interpreter running in same machine currently.
Sybase package is build on below version of perl. I could see that version in the README file of sybase modues
bash-4.1$ /usr/bin/perl -v
This is perl, v5.10.1 (*) built for x86_64-linux-thread.
I am able to use this interpreter in script and compile successfully when I use sybase supported functions to fetch from db*
1st interpreter
test1.pl
#!/usr/bin/perl
2nd perl interpretor came with oracle sdk package.
its supporting only oracle fucntions to interact with Db
bash-4.1$ /home/oracle/12.2.0/client_1/perl/bin/perl -v
This is perl 5, version 22, subversion 0 (v5.22.0) built for x86_64-linux-thread-multi->this is supporting only oracle*
test2.pl
#!/home/oracle/12.2.0/client_1/perl/bin/perl
I tried to include oracle modules from this path /home/oracle/12.2.0/client_1/perl/bin/perl while running a script using perl bin from /usr/bin/perl path and #INC file i pointed to /home/oracle/12.2.0/client_1/perl/DBD/Oracle.pm it will throw error.
So I found oracle build on 1 perl version can't be included with other version of perl
test3.pl
#!/home/oracle/12.2.0/client_1/perl/bin/perl

Can I have 1 perl interpretor version supporting both Sybase and Oracle functions?
I am not talking about the DBI module to connect to to oracle and sybase.
I meant functions used using database handlers to support oracle and sybase after connection.
I managed to follow the below steps
Downloaded DBD-Oracle-1.73_01.tar.gz and tried to install got erros. So downloaded and installed the below dependencies first
2.downloanded dependencies ExtUtils-MakeMaker-7.4 and ExtUtils-ParseXS-35.tar.gz
downloaded a oracle sdk package 12.2.0 . it has perl.jdk,plsql,sqlplus.. etc
oracle/12.2.0/client_1/perl
set ORACLE_HOME =/oracle/12.2.0/client_1 and LD_LIBARRY_PATH=oracle/12.2.0/client_1/perl
cd DBD-Oracle-1.73_01/
--execute using perl v5.10 (perl Makefile.PL)
make && make install -> this step is throwing lot of errors
I am assuming oracle driver module and along with oracle sdk clients , can there be any kind of version mismatch here ?

The standard way to talk to Sybase databases is using Perl's DBI (database interface) module and DBD::Sybase (which is the database driver for Sybase). Similarly, for an Oracle database, you'd use DBI together with DBD::Oracle.
It is perfectly possible to have both of these modules installed in the same Perl installation. It probably makes most sense to add DBD::Oracle to the version of Perl in /usr/bin/perl. You can do that by running
$ sudo cpan DBD::Oracle
on your command line. Note that you will need sudo access on the system and it will also need a C compiler and the Oracle development libraries.
If you have problems when you try it, post details of the errors you get in a new question here and we'll try to help you.
