====== Alarm Sync - Remote Database Test Config Setup ======
Author: Andrew Kavanagh

**Disclaimer** This Wiki was created to facilitate the testing process of Database Alarm Sync Operations. This guide is only concerned with outlining the basic configuration that is necessary for testing the EMS's capabilities to retrieve raw alarm data by means of database query and make this data available to the RDF for further processing. This set-up configuration is NOT suitable for testing the capacity of the RDF to process this data to active alarms in our applications.
====== Basic Configuration Requirements For Testing ======

  * Remote Database Configuration
  * Remote Discovery Scripts
  * Alarm Sync Setting
  * Network Element


==== Remote Database Configuration ====
Holds relevant configuration information for estiablishing connections to remote databases for alarm sync.
Such as driver information, connection URLs, usernames and password and login script. 
Represented by a domain class in the SNMP application. It provides convenient behaviours for establishing connections
to targeted remote databases.

**Schema**
<code>
id
version
name
user_name
password
driver
connection_url_prefix
datasource_required
login_script_id
</code> 

== Test Entry Remote Database Configuration ==

INSERT INTO remote_database_configuration (version,name,user_name,password,driver,connection_url_prefix,datasource_required, login_script_id) VALUES ('1.72','TestRemoteDB','reader','ozzrules','com.mysql.jdbc.Driver','jdbc:mysql:%%//%%', false, ${ID Of Your DB RDF Login Script});

==== Remote Discovery Scripts ====

In order to test alarm synchronisation through DB query requires a minimum of 4 basic remote discovery scripts.
From the remote discovery script controller in the SNMP manager application create 4 scripts of the following
types:

  * DB Login Script(Note - Ensure DB Server For AS Is Accessible From Current QA Server)
  * Alarm Sync Path
  * Current Alarm Parser
  * Disabled Alarm Parser
  
**DB Login Script**

==== Test Alarm Sync Setting  ====
An alarm sync setting for database sync is necessary so it can be associated with Network Elements which support such operations.
The relevant ID's of the test remote discovery script you created above are inserted into a test alarm sync setting entry. See query outline below:

<code>
INSERT INTO alarm_sync_setting (version,name,retrieve_path_script_id,current_alarm_get_type,current_alarm_mib_id,current_alarm_parse_script_id,disabled_alarm_get_type,disabled_alarm_mib_id,disabled_alarm_parse_script_id,disabled_alarm_cache_expiry_days,parameter_populate_script_id,max_running_time)
VALUES (0,'TestDBSync',${IDOfTestAlarmSyncPath},'DB_QUERY',null,${IDOfTestCurrentAlarmParser},'DB_QUERY',null,${IDOfTestDisabledAlarmParser},30,null,10);
</code>

==== Network Element ====
A test controller needs to be selected from the current QA server. **Please ensure this controller has active alarms or at least - an active alarm history**. This controller and its children need to be assigned the key of the Test remote database configuration entry which was created at the start of this Wiki. This is important as the SNMP manager application will use this key to instantiate a Remote Database Connection Manager which handles alarm sync DB tasks on the remote database server.

The test controller and its children also need to be assigned the key of the alarm sync setting which was created in the previous step of this wiki.

**Network Element - Remote Database Connection Manager Assignment**
<code>
update network_element set remote_database_manager_configuration_id = ${Id Of Remote Database Configuration} where id = ${controllerID} or parent_id = ${controllerID}
</code>

**Network Element - Alarm Sync Setting Assignment**
<code>
update network_element set alarm_sync_setting_id = {Id Of Test Alarm Sync Setting} where id = ${controllerID} or parent_id = ${controllerID}
</code>
