Methods, systems and computer program products for an intelligent processor for user-provided routines (IPUR) in a transaction processing system are provided. An interface module, interposed between a transaction processing module and a user-provided routine intercepts a request for an operation. If the user-provided routine is supported for the request, the interface module asynchronously passes the request to the user-provided routine and synchronously passes the request to the IPUR. Thus, the IPUR learns the processing of the user-provided routine, which eventually can be removed from the transaction processing system.

Intelligent processor for user-provided routines in a transaction processing system

Methods, systems and computer program products for operating an output processor a transaction processing system are provided. Aspects include receiving a request by an output processor to deliver an output message having a plurality of message segments and obtaining a target buffer size. Aspects also include allocating an output buffer for the output message, the output buffer having the target buffer size and iteratively obtaining a message segment of the plurality of message segments and storing the message segment in the output buffer. Based on a determination that all of the plurality of message segments have been stored, aspects include delivering the output message. Based on a determination that the output buffer is full and that all of the plurality of message segments have not been stored in the output buffer, aspects further include increasing the target buffer size to a maximum buffer size.

Output processor for transaction processing system

According to embodiments a technique for utilizing an error prediction an avoidance component for a transaction processing system is provided. The technique includes identifying critical functions of the transaction processing system, and collecting usage data. The technique also includes determining a focus area based on the usage data for each of the critical functions, and generating a data message for the focus area, the data message combining internal data and the usage data. The technique includes transmitting the data message to a data processing component (DPC), the data message includes DPC timer information used by the DPC for performing a summarization process, and receiving a summary message from the DPC based on the summarization process performed by the DPC. The technique also includes identifying a summary message focus area from the summary message, and determining a condition of the summary message focus area of the summary message.
