Handle CORS Client-side

Cross-origin resource sharing (CORS) is a mechanism that allows restricted resources (e.g. fonts) on a web page to be requested from another domain outside the domain from which the first resource was served. This is set on the server-side and there is nothing you can do from the client-side to change that setting, that is up to the server/API. There are some ways to get around it tho.

Sources : MDN - HTTP Access Control | Wiki - CORS

CORS is set server-side by supplying each request with additional headers which allow requests to be requested outside of the own domain, for example to your localhost. This is primarily set by the header:

Access-Control-Allow-Origin

First of all, it just seems like doing anything with Oracle is obnoxiously painful for no good reason. It's the nature of the beast I suppose. cx_oracle is a python module that allows you to connect to an Oracle Database and issue queries, inserts, updates..usual jazz.

Step 1:

sudo apt-get install build-essential unzip python-dev libaio-dev

	# It is intended to be used as mount.afuse in command line. F.e. in /etc/fstab you may mount directory like:
	# afuse# /mnt/remote afuse auto 0 0
	# And then as regular user just do:
	# $ cd /mnt/remote/[email protected]/remote/path
	# and folder /mnt/remote/[email protected] will be mounted automatically!

	# On Mac some also recommend add defer_permissions,noappledouble mount options.
