The present invention relates to a method for the dynamic creation or reconfiguration of a contact group listing based upon retrieved metadata. The method comprising identifying a contact that is to be added to a primary contact list, the primary contact list being configured to be accessed by at least one sub-list group, wherein sub-list groups are associated with predetermined metadata classification criteria. The method further comprises interrogating data sources in order to identify metadata that is associated with the contact, and retrieving from the data sources all metadata that has been associated with the contact. The retrieved metadata is subsequently utilized to dynamically generate or reconfigure sub-list groupings in accordance with the information that is retrieved from the metadata.

Dynamic group creation or reconfiguration based upon available metadata

A computer system and storage medium that, in an embodiment, receive an allocation request for a resource and registers the resource as a non-voting participant if the resource desires to delegate commit voting to another resource. The registered resource is then prohibited from participating in an enclosing transactional context and instead is informed when the transaction completes. The resource is enlisted as a voting participant if the resource does not desire to delegate commit voting. In this way, when multiple resources are used in a transaction, a resource may be registered and receive notifications of transaction completion instead of being enlisted and voting on commit decisions. The result of a transaction in which a single resource takes responsibility for a number of other resources is that transaction completion avoids the two-phase commit protocol and the resulting performance degradation.

Registering a resource that delegates commit voting

An apparatus, program product and method monitor the state of a cache during a cache preload operation in a clustered computer system such that the monitored state can be used after a failover to potentially avoid the need to restart the cache preload operation from the beginning. In particular, by monitoring the state of the cache during a cache preload operation, any data that has been preloaded into a cache prior to a failure may be retained after a failover occurs, thus enabling the cache preload operation to continue from the point at which it was interrupted as a result of the failure.

An instant messaging system for providing transparent participation of third parties in instant messaging, the system comprising: a first server and a second server configured to create a first chat session between a first chat party and a second chat party, communication in the first chat session being bidirectional between the first chat party and the second chat party, the first chat session being a sub-chat of a chat thread, the first server is further configured to create a second chat session between the first chat party and a third chat party, communication in the second chat session being bi-directional between the first chat party and the third chat party, the second chat session being another sub-chat of the chat thread, the third chat party enabled to passively participate in the first chat session while actively communicating with the first chat party, and the third chat party and second chat session being transparent to the second chat party.

A method, apparatus, system, and signal-bearing medium that, in an embodiment, receive an allocation request for a resource and registers the resource as a non-voting participant if the resource desires to delegate commit voting to another resource. The registered resource is then prohibited from participating in an enclosing transactional context and instead is informed when the transaction completes. The resource is enlisted as a voting participant if the resource does not desire to delegate commit voting.
