Abstract

A status data repository operable with a distributed processing environment including a plurality of processing regions. The status data repository includes a data storage unit adapted to store status data representative of the availability of the plurality of processing regions. The status data repository is adapted to share stored status data with a client device so as to enable the client device to obtain information regarding the availability of one or more of the plurality of processing regions.

First claim

What is claimed is:

1. A computer-implemented method of facilitating processing in a computing environment, said computer-implemented method comprising:
establishing a connection, by a client device, to a server of a plurality of servers of a distributed processing environment;
maintaining, by the client device, an affinity data structure identifying one or more outstanding affinities that the client device has with one or more specific servers of the plurality of servers with which the client device has lost contact, wherein the one or more outstanding affinities were created during a synchronization operation;
based on the client device determining, with reference to the affinity data structure, that there are one or more outstanding affinities with the one or more specific servers of the plurality of servers, and while connected to the server of the plurality of servers of the distributed processing system, the client device inquiring of a shared repository separate from the client device, and coupled to the distributed processing environment, as to status of the one or more specific servers that the client device lost contact with, and with which the client device has one or more outstanding affinities;
based on the inquiring, obtaining, by the client device, information stored at the shared repository, the information comprising availability information of the one or more specific servers, wherein the availability information is indicative of a status of the one or more specific servers of the plurality of servers indicating that another server of the one or more specific servers is currently available;
determining, by the client device, to release connection to the server and reconnect with the another server of the one or more specific servers of the plurality of servers, the determining using the availability information; and
controlling, by the client device, release of the connection with the server and reconnection with the specific server of the one or more specific servers to resolve, at least in part, the one or more affinities, the controlling being based on the determining, and wherein the one or more affinities include one or more processing relationships between the client device and the one or more specific servers that the client device has lost contact with.

2. The computer-implemented method of claim 1 , wherein the shared repository is updated based on receiving availability information from the one or more specific servers of the plurality of servers.

3. The computer-implemented method of claim 1 , wherein the inquiring comprises sending polling messages to the shared repository, the sending being controlled by one or more configurable controls.

4. The computer-implemented method of claim 3 , wherein based on receiving a query from the client device, a service provides the availability information to the shared repository.

5. The computer-implemented method of claim 1 , wherein the availability information for the specific server of the one or more specific servers of the plurality of servers comprises information indicative of whether the specific server is at least one of: running or available.

6. The computer-implemented method of claim 1 , wherein the distributed processing environment comprises a cluster of servers, and wherein the cluster of servers cooperate to control a set of resources accessible to the client device via a single connection address associated with the cluster of servers.

7. A computer program product for facilitating processing in a computing environment, the computer program product comprising:
a non-transitory computer readable storage medium readable by a processing circuit and storing instructions for execution by the processing circuit for performing a method comprising:
establishing a connection, by a client device, to a server of a plurality of servers of a distributed processing environment;
maintaining, by the client device, an affinity data structure identifying one or more outstanding affinities that the client device has with one or more specific servers of the plurality of servers with which the client device has lost contact, wherein the one or more outstanding affinities were created during a synchronization operation;
based on the client device determining, with reference to the affinity data structure, that there are one or more outstanding affinities with the one or more specific servers of the plurality of servers, and while connected to the server of the plurality of servers of the distributed processing system, the client device inquiring of a shared repository separate from the client device, and coupled to the distributed processing environment, as to status of the one or more specific servers that the client device lost contact with, and with which the client device has one or more outstanding affinities;
based on the inquiring, obtaining, by the client device, information stored at the shared repository, the information comprising availability information of the one or more specific servers, wherein the availability information is indicative of a status of the one or more specific servers of the plurality of servers indicating that another server of the one or more specific servers is currently available;
determining, by the client device, to release connection to the server and reconnect with the another server of the one or more specific servers of the plurality of servers, the determining using the availability information; and
controlling, by the client device, release of the connection with the server and reconnection with the specific server of the one or more specific servers to resolve, at least in part, the one or more affinities, the controlling being based on the determining, and wherein the one or more affinities include one or more processing relationships between the client device and the one or more specific servers that the client device has lost contact with.

8. The computer program product of claim 7 , wherein the shared repository is updated based on receiving availability information from the one or more specific servers of the plurality of servers.

9. The computer program product of claim 7 , wherein the inquiring comprises sending polling messages to the shared repository, the sending being controlled by one or more configurable controls.

10. The computer program product of claim 9 , wherein based on receiving a query from the client device, a service provides the availability information to the shared repository.

11. The computer program product of claim 7 , wherein the availability information for the specific server of the one or more specific severs of the plurality of servers comprises information indicative of whether the specific server is at least one of: running or available.

12. The computer program product of claim 7 , wherein the distributed processing environment comprises a cluster of servers, and wherein the cluster of servers cooperate to control a set of resources accessible to the client device via a single connection address associated with the cluster of servers.

13. A computer system for facilitating processing in a computing environment, the computer system comprising:
a data storage unit including a shared repository coupled to a distributed processing environment; and
a client device in communication with the data storage unit, wherein the computer system is configured to perform a method, said method comprising:
establishing a connection, by a client device, to a server of a plurality of servers of a distributed processing environment;
maintaining, by the client device, an affinity data structure identifying one or more outstanding aff
