=== Domain management ===
==== Adding new testbed ====

Currently, information about resources i.e. testbeds are kept into 2 databases, scheduler database (newScheduler) and inventory database (inventory54). To add new virtual domain we need to update both databases.
There is a script addVirtualDomais.rb on internal2, /usr/share/omf-aggmgr-5.4/omf-aggmgr/ogs_loginCommon/w. Calling that script will add virtual domains into inventory database and prepare sql script to run from mysql to update scheduler database.
{{{
ruby addVirtualDomais.rb listOfdomains.txt
}}} 
listOfDomains.txt is file with following information

domainName; <listo of nodes that belong to new domain>; <domain description>

Output file is machines.sql
There is also file testbed_attributes.yaml to define necessary testbed information. 

==== Make testbed inactive ====
To remove testbed from scheduler page just mark it inactive into both databases.

For scheduler databases run

UPDATE resources set status = 'u' where name='<testbed_name>';

For inventory, change INF_status attribute to 0:

{{{
 wget -qO- 'http://new.orbit-lab.org:5054/inventory/attribute_modify?name=<testbed_name>&attribute=INF_status&value=0
}}}


==== Updating testbed information ====
To change testbed name, make it active and change list of nodes do the following:
===== Scheduler database =====
 * Make domain active in scheduler database i.e set status to 'a':
{{{
Update newScheduler.resources set status='a' where name = '<old_name>';
}}}
* Change name and description:
{{{
Update newScheduler.resources set name='<new_name>', notes='node3-3 i node4-10' where name = '<old_name>';
}}}

or with one statement
{{{
Update newScheduler.resources set status='a', name='<new_name>', notes='node3-3 i node4-10' where name ='<old_name>';
}}}

===== Inventory database =====
* Change name
It's not possible to change resource name using inventory service. This can be done directly into database. Anytime you can delete resource with <old_name> and create new one. To change resource name run flowing script:
{{{
UPDATE inventory54.resource SET name='<new_name>' where name='<old_name>';
}}}

* Make it active, i.e set INF_status to 1 if domain should appear on status page
{{{
 wget -qO- 'http://new.orbit-lab.org:5054/attribute_modify?name=<new_name&attribute=INF_status&value=1
}}}
Domain have to have INF_x_max and INF_y_max attributes. It is necessary to restart status service after these changes.
* Change description 
{{{
 wget -qO- 'http://new.orbit-lab.org:5054/attribute_modify?name=<new_name>&attribute=INF_description&value=<new_description>
}}}

===== Define list of nodes =====

* Delete old list of nodes  - currently, there is no possibility to do it trough service, it has to be done into database directly
{{{
DELETE FROM inventory54.relations WHERE subject_id=(SELECT id FROM inventory54.resources where name='<new_name>');
}}}
Pay attention, <new_name> is used because name is already changed. If you this before changing the name, than use <old_name>.
* Add nodes  - do the flowing for each node that belongs to resource i.e. testbed
{{{
 wget -qO- 'http://new.orbit-lab.org:5054/relation_add?parent=<new_name>&child=<node_name>
}}}
