Abstract

Systems and techniques are provided for identifying and tracing an individual session of a web application hosted at a server in a network communication system, based on a request message from a client requesting a function of the web application. Data stored in a database may be accessed by one or more virtual machines executing at the server via one or more data connections from a connection pool allocated to each of the virtual machines. Reference and logging information are stored for each virtual machine and corresponding connection pool, thereby enabling operations performed by each virtual machine for the requested function to be traced with a relatively high degree of granularity at each of various functional layers or tiers of the network communication system.

Claims

1. A method, comprising:

at a server hosting a web application receiving, through a communication network from a client, a request message requesting a function of the web application to be performed during a session of the web application;

establishing a plurality of data connections to a database for accessing data stored in the database during the session, based on the function of the web application requested by the request message;

initializing a connection pool including the plurality of established data connections for a virtual machine to be executed at the server, the connection pool enabling the virtual machine to access data stored in the database during the session;

initiating execution of the virtual machine at the server in order to perform operations for the requested function based on data retrieved from the database via at least one of the plurality of data connections of the connection pool initialized for the virtual machine, wherein reference and logging information for the connection pool are stored in the database, the stored reference and logging information enabling the operations performed by the virtual machine to be traced for the session of the web application; and

sending a response message from the server through the communication network to the client, based on the operations performed by the virtual machine for the function requested by the client during the session of the web application.

2. The method of claim 1, wherein the virtual machine is a Java Virtual Machine (JVM).

3. The method of claim 1, wherein the virtual machine is initiated based on commands in a startup script associated with the virtual machine.

4. The method of claim 3, wherein the initialized connection pool is allocated to the virtual machine based on properties defined in the startup script, the properties including a predetermined minimum number of data connections to be used by the virtual machine.

5. The method of claim 3, wherein the commands in the startup script are Structured Query Language (SQL) commands to be executed at the database.

6. The method of claim 1, wherein the connection pool is one of a plurality of connection pools allocated to the virtual machine for accessing data in the database during the session.

7. The method of claim 6, wherein the virtual machine is one of a plurality of virtual machines executing at the server, and each virtual machine of the server is allocated one or more of the plurality of connection pools during different sessions of the web application.

8. The method of claim 7, wherein the server is one of a plurality of servers within a clustered computing environment having one or more server clusters, each server in the clustered computing environment executing one or more virtual machines, and each of the one or more virtual machines is configured to perform operations during the different sessions of the web application.

9. The method of claim 8, wherein reference and logging information are stored for each of the plurality of connection pools in association with information identifying one or more of the plurality of virtual machines to which each connections pool is allocated and connection properties associated with each of the one or more virtual machines.

10. The method of claim 9, wherein the information identifying the one or more virtual machines includes information identifying the corresponding server in the clustered computing environment executing each of the respective one or more virtual machines.

11. The method of claim 9, wherein the connection properties associated with each of the one or more virtual machines include one or more of a status identifier, a timestamp, a session identifier identifying the session and a client identifier identifying the client associated with the requested function of the web application during the session.

12. An application server, comprising:

a network communication device configured to exchange data communications through a communication network, the communication network including at least one database accessible to the network communication device;

a processor coupled to the network communication device;

a storage device accessible to the processor; and

an application program in the storage device, the application program including a plurality of functions of a web application, wherein execution of the application program by the processor configures the application server to exchange data communications related to the plurality of functions with a client through the communication network,

wherein the processor is configured to perform functions, including functions to;

receive through the communication network from the client, a request message requesting at least one of the plurality of functions of the web application to be performed during a session of the web application;

establish a plurality of data connections to the database for accessing data stored in the database during the session, based on the function of the web application requested by the request message;

initialize a connection pool including the plurality of established data connections for a virtual machine to be executed by the processor, the connection pool enabling the virtual machine to access data stored in the database during the session;

initiate execution of the virtual machine in order to perform operations for the requested function based on data retrieved from the database via at least one of the plurality of data connections of the connection pool initialized for the virtual machine, wherein reference and logging information for the connection pool are stored in the database, the stored reference and logging information enabling the operations performed by the virtual machine to be traced for the session of the web application; and

transmit a response message through the communication network to the client, based on the operations performed by the virtual machine for the function requested by the client during the session of the web application.

13. An article of manufacture, comprising a non-transitory computer-readable medium and computer-executable instructions embodied in the medium that, if executed by a computing device, cause the computing device to perform functions, including functions to:

receive through a communication network from a client, a request message requesting a function of a web application hosted at the computing device to be performed during a session of the web application;

establish a plurality of data connections to a database for accessing data stored in the database during the session, based on the function of the web application requested by the request message;

initialize a connection pool including the plurality of established data connections for a virtual machine to be executed at the computing device, the connection pool enabling the virtual machine to access data stored in the database during the session;

initiate execution of the virtual machine at the computing device in order to perform operations for the requested function based on data retrieved from the database via at least one of the plurality of data connections of the connection pool initialized for the virtual machine, wherein reference and logging information for the connection pool are stored in the database, the stored reference and logging information enabling the operations performed by the virtual machine to be traced for the session of the web application; and

send a response message from the computing device through the communication network to the client, based on the operations performed by the virtual machine for the function requested by the client during the session of the web application.

14. The article of claim 13, wherein the virtual machine is a Java Virtual Machine (JVM).

15. The article of claim 13, wherein execution of the virtual machine is initiated based on commands in a startup script associated with the virtual machine.
