Abstract

In accordance with an embodiment, described herein is a system and method for supporting proxy data sources in a multitenant application server environment, such as Java SE and Java EE environments. In multitenant environments, various tenants can have data sources that an administrative application can access without needing to know the actual data sources. A system and method provide a proxy data source mechanism such that applications in Java EE and Java SE environments can access tenant data sources, each tenant data source having a JNDI name that is tenant or partition specific, through the proxy data source, the proxy data source comprising a JNDI name which is not tenant or partition specific. The proxy data source can also provide for switching between tenant data sources based upon a caller context.

Claims

1. A system for proxy data source support in a multitenant application server environment, comprising:

one or more computers, including an application server environment executing thereon, together with

a plurality of deployable resources which can be used within the application server environment,

one or more resource group templates, which define groupings of deployable resources within a domain, and

one or more partitions, wherein each partition provides an administrative and runtime subdivision of the domain, that can be associated with a tenant; and

a proxy data source, the proxy data source enabling an application running within the application server environment to access a first of a plurality of data sources, the proxy data source comprising a JNDI name that is not tenant specific;

wherein the proxy data source uses a caller context to enable the application running within the application server environment to access the first of the plurality of data sources.

2. The system of claim 1, wherein the plurality of data sources comprises tenant data sources, each tenant data source associated with at least one of the one or more partitions, each tenant data source comprising a tenant specific JNDI name.

3. The system of claim 2, wherein the proxy data source is configured to switch the application access from the first of a plurality of data sources to a second of the plurality of data sources, the switching based upon a change in the caller context.

4. The system of claim 2, wherein each of the tenant data sources are further associated with one of a plurality of tenant databases, and wherein the proxy data source further uses the caller context to enable the application running within the application server environment to access at least one of the plurality of tenant databases.

5. The system of claim 1, further comprising:

a caller context module, the caller context module providing the caller context to the proxy data source.

6. The system of claim 1, wherein the application server environment supports a Java Standard Edition (SE) environment.

7. The system of claim 1, wherein the application server environment supports a Java Enterprise Edition (EE) environment.

8. A method for proxy data source support in a multitenant application server environment, comprising:

providing, at one or more computers, including an application server environment executing thereon,

a plurality of deployable resources which can be used within the application server environment,

one or more resource group templates, which define groupings of deployable resources within a domain, and

one or more partitions, wherein each partition provides an administrative and runtime subdivision of the domain, that can be associated with a tenant; and

enabling, by a proxy data source, an application running within the application server environment access to a first of a plurality of data sources; and

a transaction manager within the application server environment, the proxy data source comprising a JNDI name that is not tenant specific;

wherein the proxy data source uses a caller context to enable the application running within the application server environment to access the first of the plurality of data sources.

9. The method of claim 8, wherein the plurality of data sources comprises tenant data sources, each tenant data source associated with at least one of the one or more partitions, each tenant data source comprising a tenant specific JNDI name.

10. The method of claim 9, wherein the proxy data source is configured to switch the application access from the first of a plurality of data sources to a second of the plurality of data sources, the switching based upon a change in the caller context.

11. The method of claim 9, wherein each of the tenant data sources are further associated with one of a plurality of tenant databases, and wherein the proxy data source further uses the caller context to enable the application running within the application server environment to access at least one of the plurality of tenant databases.

12. The method of claim 8, further comprising:

providing a caller context module, the caller context module providing the caller context to the proxy data source.

13. The method of claim 8, wherein the application server environment supports a Java Standard Edition (SE) environment.

14. The method of claim 8, wherein the application server environment supports a Java Enterprise Edition (EE) environment.

15. A non-transitory computer readable storage medium, including instructions stored thereon for proxy data source support in a multitenant application server environment which when read and executed by one or more computers cause the one or more computers to perform steps comprising:

providing, at one or more computers, including an application server environment executing thereon,

a plurality of deployable resources which can be used within the application server environment,

one or more resource group templates, which define groupings of deployable resources within a domain, and

one or more partitions, wherein each partition provides an administrative and runtime subdivision of the domain, that can be associated with a tenant; and

enabling, by a proxy data source, an application running within the application server environment access to a first of a plurality of data sources; and

a transaction manager within the application server environment, the proxy data source comprising a JNDI name that is not tenant specific;

wherein the proxy data source uses a caller context to enable the application running within the application server environment to access the first of the plurality of data sources.

16. The non-transitory computer readable storage medium of claim 15, wherein the plurality of data sources comprises tenant data sources, each tenant data source associated with at least one of the one or more partitions, each tenant data source comprising a tenant specific JNDI name.

17. The non-transitory computer readable storage medium of claim 16, wherein the proxy data source is configured to switch the application access from the first of a plurality of data sources to a second of the plurality of data sources, the switching based upon a change in the caller context.

18. The non-transitory computer readable storage medium of claim 16, wherein each of the tenant data sources are further associated with one of a plurality of tenant databases, and wherein the proxy data source further uses the caller context to enable the application running within the application server environment to access at least one of the plurality of tenant databases.

19. The non-transitory computer readable storage medium of claim 15, the steps further comprising:

providing a caller context module, the caller context module providing the caller context to the proxy data source.

20. The non-transitory computer readable storage medium of claim 15, wherein the application server environment supports one of a Java Standard Edition (SE) environment or a Java Enterprise Edition (EE) environment.
