Bad script file for Ubuntu --with-oracle

[AlphaGeek509]

There are some documentation mistakes that prevent Oracle from being properly installed.

1. The readme file expelectly calls out `instantclient_19_5'. Oracle doesn't offer version 19.5 of the basic and sdk instantclients respectfully.

... README
After navigating to the Oracle website you'll want to download the basic and sdk instant client files:
instantclient-basic-linux.x64-18.5.0.0.0dbru.zip
instantclient-sdk-linux.x64-18.5.0.0.0dbru.zip
...

I corrected the script by modifying line 416 from
echo "/opt/oracle/instantclient_19_5" >/etc/ld.so.conf.d/oracle-instantclient.conf
to
echo "/opt/oracle/instantclient_18_5" >/etc/ld.so.conf.d/oracle-instantclient.conf

2. Pecl install is invalid for PHP 7. According to their website to download and install OCI8 for PHP you have to use
   pecl install oci8-2.2.0
   The script on line 418 needs to be changed to since DreamFactory still uses PHP 7. NOTE - I did change the instantclient reference to 18_5. That matches the aforementioned note.
   printf "instantclient,/opt/oracle/instantclient_18_5\n" | pecl install oci8-2.2.0
