# NOTES on mysql:
#  - CREATE DATABASE oc_autotest;
#  - CREATE USER 'oc_autotest'@'localhost' IDENTIFIED BY 'owncloud';
#  - grant all on oc_autotest.* to 'oc_autotest'@'localhost';
#
#  - for parallel executor support with EXECUTOR_NUMBER=0:
#  - CREATE DATABASE oc_autotest0;
#  - CREATE USER 'oc_autotest0'@'localhost' IDENTIFIED BY 'owncloud';
#  - grant all on oc_autotest0.* to 'oc_autotest0'@'localhost';
#
# NOTES on pgsql:
#  - su - postgres
#  - createuser -P oc_autotest (enter password and enable superuser)
#  - to enable dropdb I decided to add following line to pg_hba.conf (this is not the safest way but I don't care for the testing machine):
# local	all	all	trust
#
#  - for parallel executor support with EXECUTOR_NUMBER=0:
#  - createuser -P oc_autotest0 (enter password and enable superuser)
#
# NOTES on oci:
#  - it's a pure nightmare to install Oracle on a Linux-System
#  - DON'T TRY THIS AT HOME!
#  - if you really need it: we feel sorry for you
