A method, system, and computer program product that includes a processor assigning a network connection to an application, based upon the application requesting the network connection from a pool of network connections for connecting applications to a network resource, the assigned network connection for communicating a message with the network resource. The processor replaces the assigned network connection in the pool with a placeholder comprising configuration data of the assigned connection. The processor determined a period of inactivity of the assigned network connection, and the processor returns the assigned network connection to the pool, based upon the period reaching a defined threshold of inactivity.

Connection pool management

Batch compression management of messages. A message being sent to a batch for transmission is intercepted. The message is assigned to a batch pool, in which multiple batch pools are provided as sub-sets of the batch. The assigning of the message to the batch pool is based on a similarity of properties of the message with other messages and determined by looking up the properties in a batch pool mapping database. The message is added to the batch pool or a new batch pool is created for the message. A batch pool of messages is compressed using a dictionary of the properties common to at least some of the messages in the batch pool. The compressed batch pools are transmitted over an input/output channel.

Batch compression management of messages

An integration flow is monitored to determine a processing location of a message. The integration flow includes a route, one or more nodes, and one or more secure connectors. A first message is received by the integration flow. A central processing unit serialization load is received including a serialization of the first message on a first secure connector and a deserialization of the first message on a second secure connector. A processing load of the first message running on a first node of the one or more nodes is received. A first threshold of a processing load of the first message is received. The first threshold is determined to have been reached. Based on the first threshold being reached, a processing location of the integration flow is altered such that the first message is processed on a second node of the one or more nodes.

Optimization of integration flows in cloud environments

Methods, computer program products, and systems are presented. The methods include, for instance: obtaining a native code having a large number of counters embedded for profiling. Use cases that is serviced by the native code is identified and respective use case profiles representing performance characteristics of a corresponding use case are created. Best predictors identifying one of the use case profiles are determined and variants for a production code is created with only the best predictors instead of the large number of counters. The variants are produced with the use case profiles to to a production environment for performing the use cases.

Static optimization of production code for dynamic profiling

A method and system for handling sensitive data required by an application in a secure computer system. The secure computer system transforms sensitive data in a request message from a data format required by the application into a data format required by a service in an external computer system. The secure computer system tokenizes the sensitive data by replacing the sensitive data with tokenized data and stores a mapping between the sensitive data and the tokenized data in the secure computer system. The secure computer system sends the request message to an external computer system and receives, from the external computer system, a response message that includes annotations for the tokenized data with transform instructions for transforming the transformed sensitive data from the data format required by the service into the data format required by the application. The secure computer system replaces the tokenized data with the sensitive data.

Handling sensitive data in an application using external processing

A method and system for handling sensitive data required by an application in a secure computer system. An external computer system that is external to the secure computer system receives a transformed request message that includes one or more data aspects having tokenized data that has replaced transformed sensitive data after sensitive data in the one or more aspects had been transformed from a data format required by a service in the external computer system into a data format required by the application. The external computer system generates a response message from the transformed request message by including, in the response message, annotations with transform instructions for transforming the transformed sensitive data, from the data format required by the service into the data format required by the application, after the tokenized data has been replaced by the transformed sensitive data in the one or more data aspects.

A method and system for secure message handling of an application across deployment locations. The application is analyzed to identify processing nodes referencing one or more data aspects having deployment constraints on locations in which aspect data in the one or more data aspects may be deployed. It is ascertained whether the one or more data aspects are accessed by an identified processing node of the application. If so, a restriction is determined for the identified processing node based on deployment constraints included in the accessed one or more data aspects and the identified processing node is deployed according to the determined restriction for the identified processing node. If not, the identified processing node or a preceding processing node is marked to indicate a required tokenization of the one or more data aspects, wherein the tokenization removes the deployment constraints for the identified processing node.

Extraction and transformation of executable online documentation

Managing connections for execution of a client software application. A client software application is analyzed before execution of the application using code analysis and, optionally non-functional metadata analysis, of the application to determine one or more classifications of operations of the application. A mapping of application operation classifications to server characteristics suited to the application operation classifications is maintained. Multiple servers currently available to process at least a portion of the client software application may be monitored, and each of the multiple servers may be characterized according to their performance and resources. The classifications of operations of the analyzed application may be compared to the characteristics of the multiple servers currently available using the mapping, and a server may be selected based on the comparison.

Publish/subscribe messaging using a message structure carried out at a messaging intermediary system is provided. A plurality of lists to which publishing entities can publish messages and to which subscribing entities can subscribe to messages is maintained. A list for messages conforming, at least partly, to a common message structure is provided. A request from a publishing entity or a subscribing entity is matched to one or more provided lists by comparing a message having a message structure or an abstract representation of one or more messages to the provided lists. Messages conforming, at least partly, to the common message structure via the list are shared.

Publish/subscribe messaging using message structure

A messaging system comprises a plurality of connected components and including a schema defining fields for messages, at least one field defined as non-essential. A mechanism for operating the messaging system comprises the steps of collecting one or more performance metrics for one or more components of the messaging system, determining that at least one performance metric has crossed a predetermined threshold, informing one or more components of the messaging system that a surge in workload has occurred, and the informed components removing non-essential fields from transmitted messages and/or not processing non-essential fields from received messages.
