Managing Backend Services

Managing Backend Services

The AgileApps Cloud platform has several backend services. Each of them can be run on a different server, to improve performance and scalability. They can be disabled, as well, if they are not used.

It is highly recommended that the customer-facing web server is not used for the backend services. Instead, they should run in one or more dedicated instances of LongJump, running on one more separate servers.

Important: Each of the services should enabled on only one server--not on multiple servers.

About the Backend Services

An Application Server instance can run one or more of the following services. Enabling and disabling them determines which instance they run in--or whether they are available at all.

Service	Default Status	Description
Report Scheduler	Disabled	Runs scheduled reports when they're due
Import	Disabled	Imports of data into the database
Export	Disabled	Exports data from the database
Memcached	Disabled	Data caching mechanism (installed separately)
Marketing	Disabled	Handles email campaigns
Bounce	Disabled	Handles bounced emails that result from such campaigns
Quartz	Enabled	Time keeper for all scheduled events.

Configuring Backend Services at Installation

Backend services can be figured at installation, using the installation.properties file. It looks like this:

# Specify Java Home Directory
    java_home = /opt/jdk1.6.0_12
# Specify MYSQL parmaters
    mysql_port =  3306
    mysql_username = root
    mysql_password =  mysql123
    mysql_host = localhost
# Specify Services to be enabled at installation/upgrade [ 0 - disable / 1 - enable ]
    report_scheduler_server = 1	Kicks off scheduled reports and email.
    import_server = 1      	Imports CSV data into LongJump.	
    export_server =  1		Exports data from LongJump.
    marketing_server = 1	Sends marketing emails.
    bounce_server = 1		Handles bounced emails.
    quartz_server = 1		Enables scheduling on the server.
    memcached_server = 1	Enables memcached, if it is installed.

After changing installation.properties, run the configuration script:

# ./configure.pl
