You will find here a basic access to all TANGO database components:
an online status of the database,
the devices management and creation,
the properties and
attributes management for devices and classes
and finally a brief description of how the database
is accessed from this page.
Online status
The online status of the database as returned by
the command "DbInfo" from the TANGO Databasedevice server. It shows the
name of the database, since when the database has been running,number of
devices registered, exported, number of hosts and number of device, class
and attribute, properties in the database.
Remove from the TANGO database a device and all its associated properties
and attributes.
WARNING once removed there will be no way to regenerate the information.
Remove from the TANGO database a server, all the devices defined for this
server and therefore also all the properties and attributes associated to
these devices.
WARNING once removed there
will be no way to regenerate the information.
Query and add properties to the TANGO database for
Devices and
Classes.
Browse all Device Properties defined
Browse the entire database (not enter properties at the moment). It's also
possible to browse the database using a Java standalone application called
/segfs/tango/bin/JiveDb
Query and add attributes to the TANGO database for
Devices and
Classes.
Add an Attribute to a Device
Store in the database a device attribute and store also
a single property for that attribute. If the attribute doesn't already exist
then it will be created. If the attribute already exists then the property
given here will be added to the list of properties of that attribute.
Store in the database a Class attribute and store also
a single property for that attribute. If the attribute doesn't already exist
then it will be created. If the attribute already exists then the property
given here will be added to the list of properties of that attribute.
The TANGO database web interface
uses an html page with forms (this page) to input user requests.
Each form is submitted to a Java servlet running on a servlet enabled http
daemon. The servlets connect to the TANGO database device server
using CORBA (ORB from OOC) and execute
commands on the database using the TANGO cmd_inout() method (see the TANGO
Database
User Guide for the list of commands). The servlet returns the result
as an html page which is then displayed in the user's browser. Simple isn't
it!
