The URL for the file that describes the local applications.
The CL-CEC needs to read this file when it starts up to determine what
it may run. The URL normally points to a local file but may point to
a public web-server.
org.astrogrid.registry.query.endpoint
The service endpoint (or access URL) for querying a registry web-service. The CL-CEC
will use this registry to locate servers in VOSpace. Therefore, if this
entry is not set correctly you will find that the CL-CEC will not be able to
complete jobs that read or write files in VOSpace.
The default value points to AstroGrid's central reference registry. This
value will most probably work satisfactorily for your CL-CEC. However,
you may be able to get better performance by changing to a different
registry, e.g. one with lower load or closer on the network to the CL-CEC.
You will definitely have to change to change reference registry if your
VOSpace assets are on servers not known to AstroGrid.
org.astrogrid.registry.update
The service endpoint (or access URL) for updating a registry via its
web service. The CL-CEC will use this registry to register itself and its
applications. Therefore, if you do not complete this entry the CL-CEC will
not be able to register by itself. (You could then register it manually,
by writing the registration documents yourself.)
AstroGrid strongly recommends that you run your own publishing registry and
register your CL-CEC (and other services) in that. The main reference
registries in the VO then harvest the registrations from your publishing
registry. This gives you tight control over the registry metadata for
your services and makes it easier for you to manage your own resources
(finding all your own registrations in a large, reference registry can
be trying).
You can, currently,
register in the central AstroGrid reference registry. However, in later
versions of the AstroGrid system this will no longer be allowed and you
will have to use your own registry.
The default value for this environment entry specifies the server "localhost"
and the port number 8080. This won't work in general; you have to
set this entry. The default is only there to show you the URL pattern for
an AstroGrid registry.
cea.job.records
The absolute path (not a URL) to the directory where the CL-CEC can store
records of its jobs. The CL-CEC keeps these files indefinitely as a record of
the jobs it has run. The files are not large.
cea.job.temp.files
The absolute path (not a URL) to a directory where the CL-CEC can store
temporary files associated with the jobs its runs. The temporary files are
data going to or from the application. They can be any size, possibly very
large.
cea.component.manager.class
The name of the Java class that manages the CL-CEC at the top level.
This is the class that defines the CEC as a CL-CEC and draws in the code
for dealing with command-line software.
You should not change this value during configuration.
