Cluster::CCS3pm
Perl wrapper for the cluster configuration service library
Usage
use Cluster::CCS;my $ccs = new Cluster::CCS();$ccs->fullxpath(1);my $ccshandle = $ccs->connect();if ($ccshandle < 1) {print "Cannot comunicate with libccs\n";exit $ccshandle;}my $rtn;my $err;$err = $ccs->get($ccshandle, '/cluster/@name', $rtn);if ($err != 0) {print "Query is not valid\n";}print "My Cluster name is $rtn\n";$err = $ccs->disconnect($ccshandle);if ($err != 0) {print "Problems disconnecting from libccs\n";}exit $err;
Overview
Cluster::CCS provides a perl XS wrapper for libccs.
Methods
new
Creates a new Cluster::CCS object.
fullxpath(value)
Enable or disable full xpath queries. Set 1 to enable, 0 to disable.This has to be set before connect() or force_connect.In order to change this value, a disconnect operation is required.
connect(void)
Initialize the connection to libccs/libconfdb/corosync objdb.Returns 1 on success or negative on failure.
force_connect(cluster_name, blocking)
Initialize the connection to libccs/libconfdb/corosync objdb.If blocking is set, it will retry the operation until it succeed.Returns 1 on success or negative on failure.
disconnect(desc)
Disconnect and free resources allocated during opertaion.Returns 0 on success.
get(desc, query, rtn)
