A method, apparatus, and computer instructions are disclosed for displaying the true status of hierarchical operations being performed in a data processing system. For example, a Z-order layering technique can be used to display simultaneously on a screen the status of a plurality of operations being performed on elements of a hierarchical structure, such as, for example, on an inverted tree directory and a plurality of its sub-trees. Advantageously, the display can be scaled to include operations being performed for many nested levels of the hierarchical structure, without having to increase the overall footprint of the display. Also, an application for copying a directory has to traverse the directory's structure only one time (e.g., during the copying operation), because the application does not need to know in advance the total number of files that have to be copied.

Method and apparatus for displaying status of hierarchical operations

Optimizing an application to reduce local memory usage. At least one executable class file of the application can be instrumented with analysis code, the executable class file including bytecode. The class file can be executed on a virtual machine, wherein during execution the analysis code generates data related to the application's use of local memory. The data related to the application's use of the local memory can be analyzed to generate a memory profile analysis. Based on the memory profile analysis, at least one portion of the bytecode can be automatically revised to reduce an amount of the local memory used by the application.

Optimization of an application to reduce local memory usage

A method of optimizing an application to reduce local memory usage. The method can include instrumenting at least one executable class file of the application with analysis code, the executable class file including bytecode. The method also can include executing the class file on a virtual machine, wherein during execution the analysis code generates data related to the application's use of local memory. The method further can include, via a processor, analyzing the data related to the application's use of the local memory to generate a memory profile analysis. The method further can include, based on the memory profile analysis, automatically revising at least one portion of the bytecode to reduce an amount of the local memory used by the application.

Under the present invention, when a configuration change for a computer system is monitored and a message corresponding thereto is issued, a response to the message will be observed. Thereafter, the configuration change, the message and the response will be logged. In logging this information, the respective times and identities of corresponding users will be stored together. Thus, if an error condition results from the configuration change, a supervisor or the like will be able to access the log file and see (among other things): (1) the configuration change that caused the error condition; (2) the identity of the user who made it; and (3) the user's response to the corresponding message that was provided.
