Golden gate postgres

Hello Gurus,

im in the process of settling up replication between oracle 12c and postgres dB 9.6

do I’ve to install odbc drivers explicitly on Linux system(RHEL 7) or by default will have them on systems or the GG software for postgres includes that drivers?

if separately ,how do I install it. I read few blogs and articles but it’s very confusing for first timers.

please any guidance or help is appreciated.

Thanks
