Abstract

Session persistence storage schemes are provided. These schemes may include identifying a change in a session attribute for an application client session, querying a session persistence table associated with the application running in the application-server environment, and updating an attribute in the record identified by the query of the session persistence table, where the query is made to a session persistence table with session attributes grouped by common traits.

Claims

1. An article of manufacture comprising:

a non-transitory computer readable medium, the computer readable medium storing instructions thereon for managing application server session persistence, the instructions, which when executed, promoting actions comprising;

managing records in a session persistence table for an application client session running in an application server environment, the managing including grouping two or more attributes of a first record by shared distinguishing traits of the attributes, which when the attributes are grouped together, reduce the number of serializations for storing the first record or the length of the first record to be serialized;

identifying a change in a session attribute for the application client session;

querying the session persistence table associated with the application running in the application server environment, the query to identify a record having the identified changed session attribute; and

updating an attribute in the first record identified by the query of the session persistence table.

2. The article of claim 1, wherein the traits comprise one or more of the following:

application background data;

a selection made by a client;

a selection made by an administrator;

a setting rejected by a client during a session;

page fragments;

or partial page settings.

3. The article of claim 1 storing instructions, which when executed, further comprise:

identifying one or more common attribute traits from a plurality of session attributes; and

grouping attributes identified as sharing one or more common traits, the grouped attributes for use with the session persistence table.

4. The article of claim 1 storing instructions, which when executed, further comprise:

using an autonomic learning algorithm for grouping attributes of the first record for improved querying or serialization or storage of the first record.

5. The article of claim 3 wherein the common traits for grouped attributes include a shared range of time required to serialize the grouped attribute.

6. The article of claim 1, wherein the first record is an array containing a plurality of rows associated with the application session.

7. The article of claim 6 wherein the rows contain groupings of session attributes, the session attributes sharing one or more traits and wherein the grouping of attributes further comprises grouping by:

time between access and serialization time, and common threading mechanisms.

8. The article of claim 1, wherein a system administrator identifies traits by which session attributes are grouped, the traits identified before the initiation of the session in which the attributes are grouped according to the trait.

9. A method comprising:

managing records in a session persistence table for an application client session running in an application server environment, the managing including grouping two or more attributes of a first record by shared distinguishing attribute traits, which when the attributes with the shared distinguishing trait are grouped together, reduce the number of serializations for storing the first record or the length of the first record to be serialized;

identifying a change in a session attribute for the application client session;

querying the session persistence table associated with the application running in the application server environment, the query to identify a record having the identified changed session attribute; and

updating an attribute in the first record identified by the query of the session persistence table.

10. The method of claim 9 wherein the traits comprise one or more of the following:

application background data;

selection made by a client;

selection made by an administrator;

setting rejected by a client during a session;

page fragments;

or partial page settings.

11. The method of claim 9 further comprising:

identifying one or more common attribute traits from a plurality of session attributes; and

grouping attributes identified as sharing one or more common traits, the grouped attributes for use with the session persistence table.

12. The method of claim 11 wherein the common traits for grouped attributes include a shared range of time required to serialize the grouped attribute.

13. The method of claim 9 further comprising:

using an autonomic learning algorithm for grouping attributes of the first record for improved querying or serialization or storage of records in the sessions persistence table.

14. The method of claim 9 wherein the first record is an array containing a plurality of rows associated with the application session.

15. The method claim 14 wherein the rows contain groupings of session attributes, the session attributes sharing one or more traits.

16. The method of claim 9 wherein a system administrator identifies traits by which session attributes are grouped, the traits identified before the initiation of the session in which the attributes are grouped according to the trait.

17. A computer comprising:

a non-transitory computer readable medium, the computer readable medium storing instructions thereon for managing application server session persistence, the instructions, which when executed, promoting actions comprising;

managing records in a session persistence table for an application client session running in an application server environment, the managing including grouping two or more attributes of a first record by shared distinguishing traits of the grouped attributes, which when grouped together, reduce the number of serializations for storing the first record and the length of the first record to be serialized;

identifying a change in a session attribute for the application client session;

querying the session persistence table associated with the application running in the application server environment, the query to identify a record having the identified changed session attribute; and

updating an attribute in the first record identified by the query of the session persistence table.

18. The computer of claim 17 wherein the traits comprise one or more of the following:

application background data, a selection made by a client, a selection made by an administrator, a setting rejected by a client during a session, page fragments, or partial page settings.

19. The computer of claim 17 storing instructions, which when executed, further comprise:

identifying one or more common attribute traits from a plurality of session attributes; and

grouping attributes identified as sharing one or more common traits, the grouped attributes for use with the session persistence table.

20. The computer of claim 17 storing instructions, which when executed, further comprise:

using an autonomic learning algorithm for grouping attributes of the first record for improved querying or serialization or storage of the first record.

21. An article of manufacture comprising:

a non-transitory computer readable medium storing instructions thereon for managing application server session persistence, the instructions, which when executed, promoting actions comprising;

identifying one or more common attribute traits from a plurality of session attributes for an application server session running in an application server environment; and

grouping attributes from the application server session in a session persistence table supporting the application server session, the grouped attributes identified as having one or more of the common attribute traits,

wherein the common attribute traits for grouping attributes in the session persistence table include a shared range of time required to serialize the grouped attribute.

22. A method of session persistence storage comprising:

identifying one or more distinguishing attribute traits from a plurality of session attributes for an application server session running in an application server environment; and

grouping attributes from the application server session in a session persistence table supporting the application server session, the grouped attributes identified as sharing one or more of the distinguishing attribute traits,

wherein the distinguishing traits for grouping attributes in the session persistence table include a shared range of time required to serialize the grouped attribute.
