Abstract: A method for committing transactions in a distributed system are provided. The method provides for receiving a request from a client to commit a transaction at a coordinator node in the distributed system, tracking a tail log sequence number for every other node in the distributed system, determining a max log sequence number associated with the transaction for each participant node in the distributed system, and committing the transaction at the coordinator node when the tail log sequence number for each participant node is greater than or equal to the max log sequence number associated with the transaction at the respective participant node.

Abstract: A data server of a data processing system is operably coupled to a database and in communication with a middleware server. A connection between the data server and the middleware server is established and managed. A set of attributes identifying trusted middleware servers is instituted with the data server. The middleware server transmits a connection request to the data server. The connection request has request attributes including identifying the connection request as being for a new connection or reuse of an existing connection with different connection request attributes. A connection with the middleware server is established by the data server based on the connection request. A connection status message is received by the middleware server from the data server indicating a status of the connection request. A trust indicator for the connection is established at the data server according to a trust status identified by the set of attributes for the middleware server.

Abstract: A computer program product and system for committing transactions in a distributed system are provided. The method, computer program product, and system provide for receiving a request from a client to commit a transaction at a coordinator node in the distributed system, tracking a tail log sequence number for every other node in the distributed system, determining a max log sequence number associated with the transaction for each participant node in the distributed system, and committing the transaction at the coordinator node when the tail log sequence number for each participant node is greater than or equal to the max log sequence number associated with the transaction at the respective participant node.
