System and method for protocol support in a multitenant application server environment

1. A system for supporting an object-based stateful protocol in a multitenant application server environment, comprising:

one or more computers, each computer including one or more microprocessors;

an application server environment executing on the one or more computers, wherein the application server environment includes a plurality of partitions, wherein at least two or more of the plurality of partitions reside on a particular server instance;

a client application that initiates a plurality of partition-level connections and one or more domain-level connections to the particular server instance using an object-based stateful protocol;

a remote Java virtual machine (RJVM) on each of the client application and the particular server instance for use in managing the partition-level and domain-level connections.

2. The system of claim 1 , further comprising

a smart stub for each partition-level connection on the client application, wherein the smart stub contains a partition name and a plurality of references to server instances in a particular cluster.

3. The system of claim 1 , wherein, in the event of a failure of a connection, the client application dynamically constructs a connection URI using the information in the smart stub to connect to a new server instance.

4. The system of claim 1 , wherein the partition-level and domain-level connections are established through a single server channel.

5. The system of claim 1 , wherein the client application is selected from a group consisting of a standalone Java application and a server instance.

6. The system of claim 1 , wherein each partition-level connection is associated with a partition context that associates that connection with a partition.

7. The system of claim 1 , each partition-level connection is associated with a token for use in identifying the connection.

8. The system of claim 1 , wherein each connection is added to a partition connection table.

9. The system of claim 1 , wherein all communications between the client application and the particular server instance pass through a traffic director in the domain.

10. The system of claim 1 , further comprising a connection manager, which references a partition connection table, to determine if an existing connection for a particular connection already exists before attempting to establish a new connection for the partition.

11. The system of claim 1 , wherein the object-based stateful protocol is T3protocol.

12. A method for supporting an object-based stateful protocol in a multitenant application server environment, comprising:

providing an application server environment executing on one or more computers, wherein each computer includes one or more microprocessors, wherein the application server environment includes a plurality of partitions, wherein at least two or more of the plurality of partitions reside on a particular server instance;

providing a client application that initiates a plurality of partition-level connections and one or more domain-level connections to the particular server instance using an object-based stateful protocol; and

providing a remote Java virtual machine (RJVM) on each of the client application and the particular server instance for use in managing the partition-level and domain-level connections.

13. The method of claim 12 , further comprising

providing a smart stub for each partition-level connection on the client application, wherein the smart stub contains a partition name and a plurality of references to server instances in a particular cluster.

14. The method of claim 12 , wherein, in the event of a failure of a connection, the client application dynamically constructs a connection URI using the information in the smart stub to connect to a new server instance.

15. The method of claim 12 , wherein the partition-level and domain-level connections are established through a single server channel.

16. The method of claim 12 , wherein the client application is selected from a group consisting of a standalone Java application and a server instance.

17. The method of claim 12 , wherein each partition-level connections is associated with a partition context that associates that connection with a partition.

18. The method of claim 12 , wherein each partition-level connection is associated with a token for use in identifying the connection.

19. The method of claim 12 , wherein each connection is added to a partition connection table.

20. A non-transitory computer readable storage medium, including instructions stored thereon which when read and executed by one or more computers cause the one or more computers to perform the steps comprising:

providing an application server environment executing on the one or more computers, wherein each computer includes one or more microprocessors, wherein the application server environment includes a plurality of partitions, wherein at least two or more of the plurality of partitions reside on a particular server instance;

providing a client application that initiates a plurality of partition-level connections and one or more domain-level connections to the particular server instance using an object-based stateful protocol; and

providing a remote Java virtual machine (RJVM) on each of the client application and the particular server instance for use in managing the partition-level and domain-level connections.
