A connection request including a connection model key and a partner system attribute of a partner system requesting a connection is received at an application server from the partner system within a distributed system. Using a predefined connection model, a determination is made as to whether the received connection model key and the received partner system attribute respectively match a configured connection model key and a configured authorized partner system attribute within the predefined connection model. A logical connection is created that includes a first unique connection name derived from the received partner system attribute in response to determining that the received connection model key and the received partner system attribute match the respective configured connection model key and the configured authorized partner system attribute within the predefined connection model.

Connection model-based control of concurrent connection count and properties

In an approach for connecting an access point in a client region to an access point within a cluster of server regions for a transaction process, a processor receives a connect request to a cluster of server regions sharing a network end point from a client region. A processor reroutes the connect request by a connection balancing mechanism to a network end point corresponding to a server region within the cluster of server regions. A processor transmits connection information to the client region, wherein the connection information allows the client region to connect to the server region within the cluster of server regions. A processor connects the server region within the cluster of server regions to the client region.

Client system communication with a member of a cluster of server systems

A computer implemented method generates a visualization of a topology of a flow of multiple transactions. One or more processors detect that a first computer system has received a current transaction initiation request from a precursory transaction. The current transaction initiation request is for an initiation of a current transaction in a computer system, and contains parameter information that is recorded by each computer in a set of interconnected computer systems on which a transaction in the other precursory transactions is executed. One or more processors identify the flow of multiple transactions based on a flow transaction identifier and an identifier of the current transaction in the computer system. The one or more processors generate a visualization of a topology map of the current transaction and the other transactions based on information in the parameter information from the current transaction initiation request.

Flow topology of computer transactions

A connection request including a connection model key and a partner system attribute of the partner system requesting a connection is received at an application server from a partner system. Using a predefined connection model, as determination is made as to whether the received connection model key and the received partner system attribute respectively match a configured connection model key and a configured authorized partner system attribute within the predefined connection model. In response to determining that the received connection model key and the received partner system attribute match the respective configured connection model key and the configured authorized partner system attribute within the predefined connection model, a connection is created that includes a first unique connection name derived from the received partner system attribute.

A visualization of a topology of a flow of multiple transactions is generated. A first computer system receives a current transaction initiation request from a precursory transaction. The current transaction initiation request is for an initiation of a current transaction in the first computer system, and the precursory transaction is part of a flow of other transactions that are upstream from the current transaction. The current transaction initiation request contains parameter information that holds a hop count, which identifies how many computer systems have received other transaction initiation requests in the flow of other transactions, and a transaction initiation count, which identifies how many transaction initiation requests have been transmitted in the flow of other transactions. A processor generates a visualization of a topology map of the current transaction and the other transactions based on information in the parameter information from the current transaction initiation request.
