Data collection is provided, in which one or more affected transactions related to one or more transaction exceptions are determined. Based on one or more features of the one or more affected transactions, one or more trace features are determined. Based on the one or more trace features, a data collection rule is generated. Data of a subsequent transaction complying with the data collection rule is collected.

Data collection in transaction problem diagnostic

A method, system, and computer program product may generate synchronous application logs. A client device may create a session with a server, and the client device may be granted privileges to receive a backend service log associated with the session. A socket accompanying the session may be created between the client and server for communicating the backend service log. The requests from the client device may be monitored at the server, and log information related to the requests may be extracted by the backend service associated with the backend service log. The extracted log information may be transferred, via the socket, to the client device.

Synchronous client-side log service

Implementations of the present disclosure relate a method, system and computer program products that dynamically compile conditional statements. According to the method, a first number of times that a first conditional statement of a plurality of conditional statements has been satisfied during execution of the plurality of conditional statements for a time period is obtained, wherein the plurality of conditional statements are compiled in a first order during the execution. Based on the first number of times and the first order, a determination is made whether the plurality of conditional statements are to be reordered. In response to a determination that the plurality of conditional statements are to be reordered, a second order of the plurality of conditional statements is determined, wherein the second order being different from the first order. The plurality of conditional statements are then compiled in the second order.

Dynamic compiling for conditional statements during execution

Provided are systems, methods, and media for concurrency conflict testing for shared resources. An example method includes identifying shared resources that are to be accessed by an application. Generating a plurality of concurrency test scenarios based on the shared resources. Analyzing a plurality of concurrency test cases to detect which concurrency test cases include a reference to the shared resources. Executing a concurrency test scenario. Performing the following while or before the concurrency test scenario is executing, obtaining analyzed concurrency test cases associated with the concurrency test scenario which referenced the shared resources, obtaining application modules pertaining to the obtained concurrency test cases, generating concurrency application modules by adding breakpoints to the obtained application modules, executing the obtained concurrency test cases until all of the obtained concurrency test cases are latched at the breakpoints, and simultaneously resuming the execution of the obtained concurrency test cases.

White box code concurrency testing for transaction processing

A computing system performs file conversion upon format expiration. A computing system evaluates a risk of expiration of a first format associated with a first format object. The computing system determines if the risk of expiration is above a threshold. The computing system identifies in response to determining the risk of expiration is above the threshold, one or more files stored in the first format for conversion. The computing system converts one or more files stored in the first format to a second format. The computing system saves the one or more files in the second format.

Format management for a content repository

A method for indexing with redundant information. The method may identify unknown code points for a document in response to an indexing request for the document. The method may further convert the identified unknown code points into a plurality of converted code points. Each set of converted code points of the plurality uses a different codepage. The method may further identify sets of same code points and sets of redundant code points from the plurality of converted code points. The method may build an index based on the sets of same code points and the sets of redundant code points.
