In a network capable of handling a number of concurrent network connections between network nodes, referred to as client and server, the client and server connection managers are customized by adding respective status handler components which add server status information requests, from client to server, and responsive status information, from server to client into message headers of messages being sent between the server and client. The supported server status information types for any given connection are defined when a connection is established through dialogue between the client and server, and then persist for the lifetime of the connection. The customizations of the server and client connection managers are modest and the increase in network traffic over the connection is proportionally very small. Moreover, status information requests can be processed and responded to quickly by attaching to messages that are being sent between the nodes.

Embodiments of the present invention provide efficient systems and methods for scaling past the Java Virtual Machine (JVM) thread limit in a Java Virtual Machine. Embodiments of the present invention can be used to ensure that a received workload is executed, even if the workload is greater than a JVM thread limit of the system, by spawning a reduced number of threads from a main process, in order to provide enough resources for the effective execution of a received workload.

Method and system are provided for automatic failover between multiple nodes in a middle-tier layer between client applications and a back-end service. The method at a first node includes: receiving a request from a client application; determining that the first node cannot service the request successfully; forwarding the request from the first node to a second peer node; receiving a response at the first node on completion of the request by the second peer node; and forwarding the response from the first node to the client application. An original path of communication between the client application and the first node is maintained. The failover of the request from the first node to the second peer node is transparent to the client application. Nodes may be registered in a group, wherein a node in a group has awareness of other nodes in the group.

A method for recording execution information for a software application executable in a computer system, the computer system including a message queue, the method comprising the steps of: generating the execution information by the software application; and recording the execution information to the message queue for subsequent retrieval, wherein the message queue is accessible by the software application and persistent with respect to the software application.

Recording execution information

A method, system, and computer programming product for returning a response directly to a transaction request originator in a customer information control system (CICS) is provided. The method can include receiving a transaction request in a CICS and allocating resources in the CICS in response to receiving the transaction request. The method additionally can include determining whether the CICS is an intended endpoint of the transaction request. Finally, the method can include extracting an address of an originator of the transaction request from the transaction request and sending a response to the originator at the extracted address upon determining that the CICS is the intended endpoint of the transaction request, but otherwise routing the transaction request to a different CICS along with the address within the transaction request.

An apparatus and method for monitoring a computer system operable for alerting an operator to failures associated with critical resource consumption and comprises: a resource monitoring component for monitoring resource consumption; a threshold setting component for setting a threshold of resource consumption between an average resource consumption value and a critical resource consumption value; a diagnostic data collection component; and a threshold crossing detection component; wherein the diagnostic data collection component is operable, in response to the threshold crossing detection component detecting a threshold crossing, to start or stop diagnostic data collection.

Apparatus and method for monitoring a computer system

A system and computer program product for assigning runtime artifacts to software components. Source code and metadata are extracted from a library, where the metadata includes a component membership for the source code. A compile unit is formed from the extracted source code and metadata. Runtime artifacts are produced from the compile unit or an element derived from the compile unit. Each runtime artifact is interrogated to determine the defined component for each runtime artifact. The determined component is recorded.
