Added by Matt Jones about 12 years ago

Updated configuration documentation in admin guide for Metacat DataONE section. Changed links in configuration utility to point at the Admin guide.

registers with the DataONE Coordinating Nodes (when you click 'Register' at the
159 159 
bottom of this form), the Node Identifier is automatically set.  **It is critical that
160 160 
you not change the Node Identifier**, as that will break the connection with the
161 
DataONE network.  The ability to edit this field is only provided for the rare case
161 
DataONE network.  Changing this field should only happen in the rare case
162 162 
in which a new Metacat instance is being established to act as the provider for an
163 163 
existing DataONE Member Node, in which case the field can be edited to set it to
164 164 
the value of a valid, existing Node Identifier.

proper operation of the node.  To act as a Member Node in DataONE, you must obtain
168 168 
an X.509 certificate that can be used to identify this node and allow it to securely
169 169 
communicate using SSL with other nodes and client applications.  This certificate can
170 
either be obtained from the DataONE Certificate Authority, or from a commercial
171 
provider of certificates. Once you have the certificate in hand, use a tool such

Once you have the certificate in hand, use a tool such
172 172 
as ``openssl`` to determine the exact subject distinguished name in the
173 173 
certificate, and use that to set the Node Subject field.  Set the Node

Certificate Path to the location on the system in which you stored the

certificate file. Be sure to protect the certificate file, as it contains the
176 
private key that is used to authenticate this node within DataONE.

The ``Synchronize`` checkbox allows the administrator to decide whether to turn on


  		




  178
  
  
    
synchronization with the DataONE network.  When this box is unchecked, the DataONE


  		




  179
  
  
    
Coordinating Nodes will not attempt to synchronize at all, but when checked, then


  		




  180
  
  
    
DataONE will periodically contact the node to synchrnize all metadata content.

The ``Enable DataONE Services`` checkbox allows the administrator to decide whether to 


  		




  
  179
  
    
turn on synchronization with the DataONE network.  When this box is unchecked, the 


  		




  
  180
  
    
DataONE Coordinating Nodes will not attempt to synchronize at all, but when checked, 


  		




  
  181
  
    
then DataONE will periodically contact the node to synchrnize all metadata content.


  		




  181
  182
  
    
To be part of the DataONE network, this box must be checked as that allows 


  		




  182
  183
  
    
DataONE to receive a copy of the metadata associated with each object in the Metacat


  		




  183
  184
  
    
system.  The switch is provided for those rare cases when a node needs to be disconnected

hour (such as ``11``) and the ``Minutes`` field to a concrete value like``15``, 


  		




  192
  193
  
    
which would change the schedule to synchronize at 11:15 am daily.

The Replication section is used to configure replication options for the node


  		




  
  196
  
    
overall and for objects stored in Metacat.  The ``Accept and Store Replicas``


  		




  
  197
  
    
checkbox is used to indicate that the administrator of this node is willing to allow


  		




  
  198
  
    
replica data and metadata from other Member Nodes to be stored on this node.  We


  		




  
  199
  
    
encourage people to allow replication to their nodes, as this increases the


  		




  
  200
  
    
scalability and flexibility of the network overall.  The three "Default" fields set


  		




  
  201
  
    
the default values for the replication policies for data and metadata on this node


  		




  
  202
  
    
that are generated when System Metadata is not available for an object (such as when


  		




  
  203
  
    
it originates from a client that is not DataONE compliant).  The ``Default Number of


  		




  
  204
  
    
Replicas`` determines how many replica copies of the object should be stored on


  		




  
  205
  
    
other Member Nodes.  A value of 0 or less indicates that no replicas should be


  		




  
  206
  
    
stored.  In addition, you can specify a list of nodes that are either preferred for


  		




  
  207
  
    
use when choosing replica nodes, or that are blocked from use as replica nodes.


  		




  
  208
  
    
This allows Member Nodes to set up bidirectional agreements with partner nodes to


  		




  
  209
  
    
replicate data across their sites. The values for both ``Default Preferred Nodes``


  		




  
  210
  
    
and ``Default Blocked Nodes`` is a comma-separated list of NodeReference identifiers 


  		




  
  211
  
    
that were assigned to the target nodes by DataONE.


  		




  
  212

Once these parameters have been properly set, us the ``Register`` button to


  		




  195
  214
  
    
request to register with the DataONE Coordinating Node.  This will generate a


  		




  196
  215
  
    
registration document describing this Metacat instance and send it to the
