SYNOPSISccs_test [options] <command>
DESCRIPTIONccs_test is part of the Cluster Configuration System (CCS). It is a
diagnostic tool that reads cluster.conf information to test ccsd.

COMMANDS
connect [force] [block] [cluster name]
This command creates a connection to ccsd. It returns a
descriptor, which is used as an parameter to other commands.
The 'force' key-word is used to establish a connection to ccsd
in the absence of a quorate cluster manager.
The 'block' key-word is used (with the 'force' key-word) to tell
ccsd to keep broadcasting for a valid configuration file until
one is found.
The 'cluster name' is used (with the 'force' key-word) to spec‐
ify that only configuration files containing the given cluster
name are valid possibilities.
get <desc> <request>
Get the results of a given request. The 'desc' is the number
returned from the connect command. The 'request' is a valid
Xpath request.
If 'request' results in multiple matches, the first will be
returned. Subsequent calls with the same 'request' will result
in the subsequent matches. Once all the matches have been
returned, a subsequent call will begin again with the first
result.
get_list <desc> <request>
Similar to the get command. However, issuing subsequent calls
with the same 'request' will result in all matches being
returned (one at a time), then null, then starting over with the
first result.
set <desc> <path> <value>
Sets a particular 'path' to the given 'value'. Not yet imple‐
mented.
get_state <desc>
Get the state associated with a given connection.
set_state <desc> <ncwp>
Set the current working path (cwp) to 'ncwp' for a given connec‐
tion.
EXAMPLES
To connect to ccsd:
> ccs_test connect
Connect successful.
Connection descriptor = 0
Or, if the cluster is not yet quorate and the name of the cluster is
'mycluster':
> ccs_test connect force block mycluster
Connect successful.
Connection descriptor = 0
To get the cluster name from ccsd:
> ccs_test get 0 /cluster/@name
Get successful.
Value = <mycluster>
To get the connection state:
> ccs_test get_state 0
Get state successful.
Current working path:
Previous query : /cluster/@name
To set the connection state:
> ccs_test set_state 0 /cluster
Set state successful.
After setting the connection state, note the change:
> ccs_test get_state 0
Get state successful.
Current working path: /cluster
Previous query : /cluster/@name
After setting the connection state, you can now query with an absolute or
relative path:
> ccs_test get 0 @name
Get successful.
Value = <brassow>
> ccs_test get 0 /cluster/@name
Get successful.
Value = <brassow>
To disconnect:
> ccs_test disconnect 0
Disconnect successful.
