Abstract: A system and method for employing bytecode modification techniques for tracing services within an application server. Application servers, such as those based on the Java 2 Enterprise Edition (“J2EE”) standard, include a variety of different services. In one embodiment of the invention, a group of services executed on an application server are identified for tracing. For each service in the group, a group of entry and/or exit methods to be traced are identified. The group of entry/exit methods may represent entry and/or exit points to and from the service, respectively. Once the service's method are identified, the service's bytecode is modified based on the particular group of entry/exit methods specified. The service is then executed and method invocations of the bytecode modified entry/exit methods are registered.

Abstract: A method for detecting locking states in communication and/or control appliances (SGi) dispersedly networked together by a data bus (2) compares a message currently transmitted by a communication and/or control appliance (SGi) to a previously transmitted message. It determines and the absence of a locking state of the communication and/or control appliance (SGi) if the messages are different. A message counter is encoded in the transmitted message if the messages are identical and decodes the message counter in a communication and/or control appliance (SGi) receiving the message. It determines the absence of a locking state at the communication and/control appliance (SGi) if the value of the message counter has changed relative to a previous value of the message counter of a previously transmitted message and determines a locking state of the communication and/or control appliance (SGi) if the message counter value has not changed after a specific waiting time (tw).

Abstract: A run-time monitor allows defining sets of run-time error criteria and corresponding diagnostic action to take when the run-time error criteria is satisfied. One way to define the run-time error criteria is to take a baseline measurement of run-time errors that occur during normal processing conditions. A run-time error criteria may then be defined that is based on the baseline measurement. In this manner, a rate of run-time errors that normally occur may be ignored, while a rate of run-time errors in excess of the run-time error criteria could automatically initiate diagnostic action. In this manner, the ability of a programmer to debug run-time errors is significantly enhanced.

Data from the program is packetized by the packet daemon executing on the computer and transmitted to the packet daemon executing on the remote management module, which forwards the data to a program specific daemon on the remote management module for forwarding to the client.

Abstract: Events that repeatedly occur during a detection period are intercepted and suppressed before being written to a log. When the same error has been detected a predetermined number of times within the detection period, the event logging for the event is suppressed for a suppression period. At the end of the suppression period an entry is made in the log summarizing the events during the suppression period. Additionally, diagnostic information relating to an application is collected and then stored within a high speed memory. Upon the occurrence of a triggering event, the diagnostic information from the high speed memory is stored within a data store for later use.

Abstract: An approach for determining compression intervals generally involves determining a compression interval based upon frequencies of event instances. According to the approach, event data is received that specifies instances of an event. The event data is analyzed and a compression interval is determined based upon frequencies of the instances of the event. The compression interval is selected to provide a balance between insufficient compression (under compression) and poor performance associated with over compression. Event compression may then be performed using the compression interval and report data may be generated that specifies the occurrence of the event.

Abstract: Data stored in relational databases can be retrieved using a relational database query language, while data stored in a multidimensional database is typically retrieved using a multidimensional database query language. However, most users do not have a functional working knowledge of multidimensional database query languages, which leaves large amounts of data inaccessible. Further, while some relational database query languages may be translated into a multidimensional database language, the information generated by such translations is often unusable, or returns large numbers of errors. In order to obtain effective translation of a relational database query language to a multidimensional database query language effective translation and filtering needs to occur. Using effective mapping and retrieval of database metadata along with effective, customizable business logic filtering of query components, more effective and reliable results may be achieved.

Abstract: The present invention provides a session filter associated with an element to be protected in a communication network. Session requests intended for the protected element are processed by the session filter prior to being forwarded to the protected element. The protected element or a device associated therewith will provide event information indicative of undesirable session conditions, such as an overload condition, which necessitates a reduction or stoppage of incoming session requests for the protected element. The session filter will directly or indirectly receive the event information and take steps to reduce or stop the session requests being sent to the protected element. The session filter may filter the incoming session requests for the protected element and selectively send select session requests to the protected element, as well as send system protection responses to minimize the number of new session requests to devices generating or forwarding the incoming session requests.

Abstract: The chip is placed in self simulation mode. When the trace logic does not have any more data to output it changes the state of the advance signal. The clock generator detects this state change and issues one gated clock to the functional logic. This creates a new CPU state and causes the change signal to toggle, and the trace logic notes the state change in the signal. It then exports the internal state presented to it. Once it completes the export, it changes the state of advance and the process begins anew.

Abstract: A novel click-less tool system for performing user input device actions on computer systems, such as mouse clicks, automatically and without the need to mechanically perform these actions. All input is carried out by moving the cursor only. The system provides a user with visual trigger windows arranged near the position of the cursor on the screen and which becomes visible for a short period of time whenever the user mouse/input cursor stops. When the user moves the cursor and hovers over one of the visible activator windows, the click-less tool program automatically performs a preprogrammed action, then places the cursor back to where the user stopped before the trigger windows were visible. Once the action is performed the trigger windows disappear.

Action priority of the classified unknown error group is determined; and the unknown error group for which the action priority has been determined is registered in an unknown error pool database.
