A system for improving memory management in a hybrid programming environment where a server program receives a request to execute a script. The server program instructs an embedded script engine to execute the script. The server program creates a session manager to manage objects associated with the script. The objects are comprised of host objects that reside in a program memory space, and script objects that reside in an embedded script engine memory space. The session manager creates a session associated with the execution of the script, and associated objects created during the execution of the script. Upon receiving notification of completion and/or termination of the execution of the script, the server program requests invalidation and/or deletion of the objects associated with the session. Deletion of host objects immediately releases memory in the program memory space without waiting for the scheduled garbage collection.

Effective memory management for host objects in a runtime environment with embedded garbage-collected based dynamic language

Embodiments relate to an isolated program execution environment. An aspect includes receiving, by the isolated program execution environment on a computer comprising a processor and a memory, a request to run a program. Another aspect includes wrapping program code corresponding to the program as a function. Another aspect includes cloning a real global object of the isolated program execution environment to create a fake global object. Another aspect includes passing the fake global object to the function. Another aspect includes executing the function, such that the function executes the program.

A Universal TAI handles multiple identifications by means of an internal lookup table. When authenticating and authorizing requests, from a pre-registered customer, that are serviced by an application server, a reverse proxy security server receives requests of different protocols and associates user identification information of a single user with different formats based on the types and protocols of the requests. The Universal TAI determines a fundamental identification of the user from a lookup table, substitutes the fundamental identification into the requests of different protocols for the same user principal, and passes the request with the fundamental identification to the application server.

Assigning user requests of different types or protocols to a user by trust association interceptors

A method, system and program product for overriding existing functionality provided in an application programming interface (API) for a local protocol implementation is provided. The method includes providing an API for a local protocol implementation having a raw interface function that can be invoked by a client application to override existing functionality provided in the API. The method further includes defining for the raw interface function an array of pre-formed payload elements to be included for creating a customized protocol request message for requesting a protocol service from a server application using a remote protocol implementation different than the local protocol implementation, populating data for each element in the array defined, and invoking the raw interface function, which takes as input the array defined and inserts them, in order, behind a protocol message header of the protocol request message and sends the customized protocol request message to the server application.

Method, system and program product for adapting to protocol changes

A mediation server assigns customized 'plug-ins' to particular network access servers (NAS) that allow a service provider application to use a single interface to communicate with multiple types of NASs. Vendor specific details of NAS transaction processing are hidden in the customized plug-ins implementations in which a service provider application has no knowledge of such transaction processing information. The mediation server extracts a user identifier from a call request, and uses the user identifier to select a mediation handler plug-in. The mediation server then uses the mediation handler plug-in to communicate with a particular NAS. In addition, a RADIUS server uses a NAS identifier to assign a RADIUS handler plug-in to a NAS session, and uses the assigned RADIUS handler plug-in to communicate with the NAS.

Multi-vendor mediation for subscription services

Apparatus and method for automatically testing hardware and software components of a system. A request type message is generated in the software component of the system. A request-type message, including a destination address and a source address, is made to traverse the transmit channel of the system. The destination address and source address are swapped, i.e., interchanged, and the message is wrapped into the receive channel where it is forwarded to the software component for further analysis. Modification is in the transmit channel to modify the message by swapping the source address and the destination address to preclude discarding of the message by the receive channel.

Extended wrap mode with source/destination wrap

A primary ARP server and a backup ARP server are connected to an ATM communications network. The primary and backup ARP servers each have associated ATM addresses. Also, a LIS is connected to the ATM communications network. Either the primary or backup ARP server is the active ARP server and resolves IP addresses to ATM addresses for the LIS. When the backup ARP server recognizes the removal of a redundancy virtual channel connection (VCC) between the backup ARP server and the primary ARP server, the backup ARP server registers using the ATM address associated with the primary ARP server. This allows the backup ARP server to take over for the primary ARP server to become the active ARP server. In addition, a primary default gateway and a backup default gateway are connected to the ATM communications network. These default gateways have associated ATM addresses. One of the primary and backup default gateways is active at a time. The active default gateway provides routing services for hosts that do not run routing topology protocols. When the backup default gateway recognizes the removal of a redundancy virtual channel connection (VCC) between the backup default gateway and the primary default gateway, the backup default gateway registers a mapping between the ATM address associated with the backup default gateway and an IP address of the default gateway. In this manner the backup default gateway takes over for the primary default gateway to become the active default gateway.
