Abstract

A system and computer-implemented method for providing a load-balanced server architecture to end users and allowing software on the server architecture to be updated without downtime during a transition to the new software version. Run-time errors due to incompatibilities between datatypes, interfaces, deserialization methods, and classes loaded by class loaders in object oriented server software may be avoided by using the system to track a software version used in association with a particular task. By routing requests related to a particular task to a particular server running the same software version, compatibility is maintained and efforts to migrate data across software servers or add code to handle cross-version compatibility are unnecessary.

Claims20

Dependent claims

A system for providing software services, comprising:

a first software server or software module of a plurality of software servers or software modules, using a first software version to operate upon software sessions generated by the first software version, wherein the software sessions comprise at least one of serialized persistent software sessions and non-persistent software sessions;
a second software server or software module of the plurality of software servers or software modules, using a second software version to operate upon software sessions generated by the second software version, wherein the software sessions comprise at least one of serialized persistent software sessions and non-persistent software sessions;
a database storing a plurality of records, each record of the plurality of records comprising a reference to a software session and a reference to a software version;
a gateway router configured to:
receive a request to access an existing particular software session;
query the database to determine which software version is associated with the particular software session;
determine which software server or software module is executing the software version associated with the particular software session;
and
forward the request to the software server or software module determined to be executing the software version associated with the particular software session;
and
wherein, responsive to receiving the request forwarded by the gateway router, the software server or software module determined to be executing the software version associated with the particular software session is configured to:
retrieve a serialized form of the particular software session;
deserialize the serialized form;
and
provide a user interface to perform one or more operations using the particular software session.

12 more elements

A method for upgrading a software execution system from a first software version to a second software version, comprising:

receiving all client requests to the software execution system at a gateway router;
tracking, in a database connected to the gateway router, a software version used to initiate a software session associated with each client request received by the software execution system, wherein the software sessions comprises one of a serialized persistent software session and a non-persistent software session;
entering a first mode of operation wherein all newly initiated software sessions are handled by a software server or software module of the software execution system running the first software version, wherein the newly initiated software sessions comprise at least one of serialized persistent software sessions and non-persistent software sessions;
after one or more software sessions have been initiated, transitioning from the first mode of operation to a second mode of operation wherein all newly initiated software sessions are handled by a software server or software module of the software execution system running the second software version, wherein all client requests related to modifying an existing software session are forwarded to a software server or software module of the software execution system running a same software version as a software server or software module of the software execution system used to initiate the existing software session, and wherein the gateway router forwards client requests related to modifying an existing software session based on querying the database to determine the software version used to initiate the existing software session.

1 more element

A method for providing software services, comprising:

operating a first software server or software module using a first software version to operate upon software sessions generated by the first software version, wherein the software sessions comprise at least one of serialized persistent software sessions and non-persistent software sessions;
operating a second software server or software module using a second software version to operate upon software sessions generated by the second software version, wherein the software sessions comprise at least one of serialized persistent software sessions and non-persistent software sessions;
receiving, at a gateway router, a request to access a particular software session that has been previously serialized;
querying a database that stores a plurality of records, each record of the plurality of records comprising a reference to a software session and a reference to either the first software version or second software version, to determine which software version is associated with the particular software session;
determining which software server or software module is executing the software version associated with the particular software session;
forwarding the request from the gateway router to the software server or software module determined to be executing the software version associated with the particular software session;
retrieving, by the software server or software module, a serialized form of the particular software session;
deserializing the serialized form;
and
providing a user interface to perform one or more operations using the particular software session.
