摘要:
A mechanism is provided for configuring different computers of a network. Each computer plays a specific physic role (defined by an architecture of the network) and/or a specific logic role (defined by the applications running in the network). A reference model and a transition table are associated with each product to be installed in the network; the reference model specifies a target configuration for each role (defined by the components of the product to be installed), while the transition table specifies the actions required to reach each target configuration from each current configuration of the computers. A server identifies the role and the current configuration of each computer; the actions required to enforce the desired target configuration on the computer are then established and executed.

摘要:
Building a package for installing a software application on a data processing system with a distributed architecture is provided. The installation package is built using an authoring tool based on a declarative model. A descriptor is used to define a desired configuration of the system. The installation package is built declaring a discoverer element, a producer element and a consumer element into the wizard tree. During the installation process, the discoverer element detects a current configuration of the system. The producer creates a working queue dynamically, inserting the installation operations that are needed for reaching the desired configuration from the current configuration of the system. The producer then executes the installation operations defined in the working queue. In this way, the installation operations are determined at runtime.
摘要:
A method (300) of installing software applications using a wizard-based installation package (for example, built using “InstallShield”) is proposed. The installation package is defined declaring a discoverer Bean (308), a producer Bean (312), a consumer Bean (314) and a debugger Bean (315) into the wizard tree (while the product tree is left empty). During the installation process, the discoverer creates (322-346) a working queue dynamically, inserting the installation operations that are needed for reaching a desired configuration (defined in a descriptor of the software application) from a current configuration (detected at run-time). The consumer executes (348-362) the installation operations defined in the working queue in succession. Whenever an error condition is detected (352, 356, 360), the installation process is suspended (368) and the debugger is invoked (372). An administrator can browse (378) an execution log of each installation operation and update (380-383) any wrong operative parameter. The installation process is then resumed (375) without having to repeat the installation operations already executed.

A method (300) of building a package for installing a software application on a data processing system with a distributed architecture is proposed. The installation package is built using an authoring tool based on a declarative model. In the proposed method, a descriptor is used to define (309) a desired configuration of the system (specifying the software products to be installed for each role that can be played by the different target computers of the system). The installation package is build declaring a discoverer element (312), a producer element (315) and a consumer element (318) into the wizard tree (while the product tree is left empty). During the installation process, the discoverer element detects (330-332) a current configuration of the system (including the role assigned to each target computer). The producer creates (337-351) a working queue dynamically, inserting the installation operations that are needed for reaching the desired configuration from the current configuration of the system. The producer then executes (357-372) the installation operations defined in the working queue. In this way, the installation operations are determined at runtime (according to the actual structure of the system wherein the software application must be installed).

A method (300) and a corresponding system are proposed for configuring different computers of a network. Each computer plays a specific physic role (defined by an architecture of the network) and/or a specific logic role (defined by the applications running in the network). A reference model and a transition table are associated (306-312) with each product to be installed in the network; the reference model specifies a target configuration for each role (defined by the components of the product to be installed), while the transition table specifies the actions required to reach each target configuration from each current configuration of the computers. A server identifies (330-336) the role and the current configuration of each computer; the actions required to enforce the desired target configuration on the computer are then established and executed (333,339-366).
摘要:
A method, system, and computer program for installing a shared software component on a computer are proposed. The process is driven by an exploiter of this (new) shared component. If the required shared component is not available on the computer, it is installed at the desired location (specified by the exploiter). On the contrary, if another shared component is already available (for further exploiters), the process verifies whether this available shared component is at the required level. If not, the available shared component is upgraded accordingly; for example, this result can be achieved by causing the available shared component to refuse any new request and then waiting for the completion of any pending request. In this case, the install location of the available shared component is returned to the exploiter, so as to have it point to the available shared component automatically.
