Embodiment Construction

[0086] Figure 1 illustrates the functional structure of an intermediate application implementing the present invention;

[0087] In a cluster, an AOP master application (such as a transactional application) provides a certain number of services to users or clients, especially by inputting and outputting data in different forms. In a cluster, the application can be single or multi-tasking (multi-process or multi-threaded) and use a certain amount of resources. In particular, these resources may be data, eg in the form of data files, spaces of shared memory or working memory, or may be status indicators, eg in the form of signals or mutexes.

[0088] The main application is executed on one or more computers constituting a node called an operating node OP or master node. In one or more cluster nodes, a function management application called an intermediate application INT is implemented in one or more parts.

[0089] According to an embodiment, the intermediate application may ...

Abstract

This invention relates to a method for replaying, from a log file, internal events within a process belonging to a software application in a network. This method comprising the following steps: - executing at least one replay instruction by the target process, initiating a replayed operation (EVI) that returns, to this target process (PB1), at least one result datum obtained (RRJ) by this replayed operation; - performing, by a software agent (PRI) external to the restart process, a forcing process (7) comprising a forcing operation upon the target process, instead and in place of the replay result datum (RRJ), of a forced datum, (RLi), extracted from logging data. Advantageously, the target process (PB1) executes the replay instruction of its own initiative from its executable file (EXE; 7).

Description

technical field [0001] The present invention relates to a method for replaying events within a process belonging to a software application from a log (log) file. The method is particularly directed to internal events within the processes belonging to applications executing in a multi-computer environment. [0002] The field of the invention is that of a cluster or network of computers consisting of several computers working together. These clusters are used to execute software applications that provide one or more services to users. Such an application may be a single or multiple processes and may be executed on a single computer or distributed over several computers, for example as a distributed application of the MPI ("Message Passing Interface") type or of the "Shared Memory" type. [0003] In particular, the invention enables the management of such a functioning of a so-called master or primary application within a cluster, for example by means of another software applic...
