# Jails vs bhyve (https://forums.freebsd.org/threads/jails-vs-bhyve.57817/)

# bhyve - Virtualisation: Creates a blank-disk that can be used to run an entire-OS 
  (bootloader, kernel, userland, etc.) by the virtualisation software.

# Jails - OS-Level Virtualisation: Jails uses the same kernel and main resources as 
  the host OS (FreeBSD). But creates a separate and isolated userland and network-space.
  So the Jail cannot see the filesystems of the host OS.

It all depends on your hardware resources and needs. It would be a waste of resources to run FreeBSD inside Bhyve if using the same

Start spring-boot app without depending on Database?
https://stackoverflow.com/questions/23850585/how-to-start-spring-boot-app-without-depending-on-database/23875516#23875516
Spring boot apps will start fine even if DB is down or there is no DB.
Apps will pick up the connections on the fly as DB comes up which means there is no need to restart the web server or redeploy the apps.
There is no need to start the tomcat or redeploy the apps, if DB goes down from running state and comes up again.
application.yml :

spring:
  datasource:
    driverClassName: com.mysql.jdbc.Driver

Good analysis. People rush to “optimize the code” but they don’t bother to measure or look for the best algorithm.

Please note that the way how to install plugins differs from each version of Eclipse to the next one. 
The following description is for Eclipse 3.5 - 4.3. See http://subclipse.tigris.org/servlets/ProjectProcess?pageID=p4wYuA
for more detailed information by the plugin provider.

    If not installing on Windows (32-bit), i.e. on Linux, Mac OS X, or Windows 64-bit, first have a look at the notes below,
    as you first need to install Subversion for your operating system.
    In Eclipse, select the menu "Help > Install New Software".
    Enter the Update Site, depending on your version of subversion you installed:
        If you installed Subversion 1.6: http://subclipse.tigris.org/update_1.6.x
        If you installed Subversion 1.7: http://subclipse.tigris.org/update_1.8.x

Download Oracle Java JRE & JDK using a script

Oracle has recently disallowed direct downloads of java from their servers (without going through the browser and agreeing to their terms, which you can look at here: http://www.oracle.com/technetwork/java/javase/terms/license/index.html). So, if you try:

wget "http://download.oracle.com/otn-pub/java/jdk/7u4-b20/jdk-7u4-linux-x64.tar.gz"

you will receive a page with "In order to download products from Oracle Technology Network you must agree to the OTN license terms" error message.

This can be rather troublesome for setting up servers with automated scripts.
