Abstract
An apparatus, clustered computer system, and program product rely on cluster-private group names to perform accesses to groups that are resident in a clustered computer system. Thus, for a cluster-accessible group, all nodes capable of participating in a cluster are configured to map to the same cluster-private group name for that group, so that any external user that has access to the clustered computer system can access the group name and utilize the group name to initiate operations by the group.
Claims12
An apparatus, comprising:
- a memory accessible by a first node among a plurality of nodes in a clustered computer system;
- and
- a program resident in the memory and executed by the first node, the program configured to access a group that includes a plurality of members resident respectively on the plurality of nodes by receiving an access request that identifies a cluster-private group name associated with the group, wherein the plurality of members in the group map to the cluster-private group name, and processing the access request to initiate a group operation on at least a subset of the plurality of nodes that map to the cluster-private group name.
A clustered computer system, comprising:
- a plurality of nodes coupled to one another over a network;
- a group including a plurality of members resident respectively on the plurality of nodes, wherein the plurality of members in the group map to a cluster-private group name;
- and
- a program resident in a first node among the plurality of nodes and configured to access the group by receiving an access request that identifies the cluster-private group name associated with the group, and processing the access request to initiate a group operation on at least a subset of the plurality of nodes that map to the cluster-private group name.
A program product, comprising:
- a program resident in the memory and executed by a first node among a plurality of nodes in a clustered computer system, the program configured to access a group that includes a plurality of members resident respectively on the plurality of nodes by receiving an access request that identifies a cluster-private group name associated with the group, wherein the plurality of members in the group map to the cluster-private group name, and processing the access request to initiate a group operation on at least a subset of the plurality of nodes that map to the cluster-private group name;
- and
- a non-transitory computer storage medium storing the program.
