    摘要： Provided are techniques for data stream switching. While accepting data change messages from a historical data stream, in response to determining that the end of the historical data stream is approaching, consumption from a real time data stream is resumed. In accepting data change messages from one of a historical data stream and a real time data stream, a data change message identifier (DCMID) for a data change message is obtained. Then, it is determined whether the data change message is from the real time data stream. In response to determining that the data change message is from the real time data stream, the DCMID is processed against a historical data structure to determine whether the related data change message has been seen in the historical data stream. In response to determining that the data change message is from the historical data stream, the DCMID is processed against a real time data structure to determine whether the related data change message has been seen in the real time data stream. It is determined whether a threshold for a number of DCMIDs that correspond to each other in the real time data stream and the historical data stream has been met. In response to determining that the threshold has been met, there is a switch from capturing data change messages in the historical data stream to capturing data change messages in the real time data stream.

    摘要： A converged service frame format is defined to support any-to-any connections between Ethernet and Token Ring LANs. The converged service frame format is a superset of standard Ethernet frame formats defined in IEEE 802.3 specifications. Where the frame source is an Ethernet LAN, an 802.1Q tag is added. Where the frame source is a Token Ring LAN, other operations are performed, including mapping of Token Ring priority bits into an appropriate field in the converged service frame. The operations required to map either an Ethernet or a Token Ring frame into the converged service frame are performed at an edge device at a point of ingress into an intervening network. The inverse operations required to restore the Ethernet or Token Ring frame are similarly performed in an edge device at a point of egress from the network.

    摘要： A system for identifying and utilizing a secondary index to access a database using a management system without an internal catalogue of online metadata. The system receives an application request to access a database from the application program, and parses the application request to determine at least one column name and at least one table name. The system utilizes an online catalogue containing metadata to translate the column name to a field name and the table name to a segment name, wherein the segment name has an associated secondary index. The system utilizes the online catalogue to determine an associated secondary index name, and builds a database request that includes the segment name, the field name, and the associated secondary index name. The system then sends the database request to the database management system, so that the associated secondary index can be used by the database management system in response to the database request.
