An approach for sharing an asset in a peer-to-peer (P2P) network is provided. After a computer sends a request to a new node for a new subscription and prior to the computer receiving the new subscription, the new node requests a digital certificate or permission from a user. The new node receives the digital certificate or permission. The new node determines a number of P2P connections in the network does not exceed a threshold amount and determines that no bandwidth degradation exists in the network. Responsive to receiving the digital certificate or permission, determining the number of P2P connections does not exceed the threshold, and determining that no bandwidth degradation exists in the network, the new node transfers the asset to the computer and updates a local list of nodes authorized to receive assets shared by the new node by adding an identification of the computer.

Asset sharing within an enterprise using a peer-to-peer network

An approach for sharing an asset in a peer-to-peer network is provided. After determining a locally stored first list does not include meta data specifying the asset, a new node is identified. In response to receiving a subscription from the new node, a second list locally stored at the new node is received. The second list includes the meta data and an identification of a source node that has the asset. The first list is updated to include the meta data and the identification of the source node. The updated first list is searched and in response, the meta data and the identification of the source node are detected. Based on the detected meta data and identification, the source node is identified. A request to retrieve the asset is sent to the source node, and in response, the asset is received.

A method and system for sharing an asset in a peer-to-peer network. Meta data and a source node identification are received. The meta data specifies properties and content of the asset to be shared by the source node. The received source node identification and the meta data are locally stored as a couple in a catalog. Subsequently, content specifying the asset and a request to search for and retrieve the asset based on the content is received. The locally stored catalog is loaded and searched to detect the couple that includes the source node identification and meta data, where the received content matches the meta data. The source node is identified based on the detected couple. A request is sent to the source node to retrieve and share the asset, and in response, the asset is received.

An approach for replicating data is provided. A job that modifies data objects in a first system to generate a first set of changed data objects is determined to be a candidate for a job replication. Based on the job being a candidate for job replication, attributes of the job are retrieved, the retrieved attributes are sent to a second system, and an execution of the job by the second system is initiated as part of the job replication. The execution of the job causes data objects included in the second system to be modified to generate a second set of changed data objects as a replication of the first set of changed data objects.
