  • Patent number: 8954397
    Abstract: A method for replaying a simulation workload is provided. The simulation workload identifies a plurality of workload parts. Each workload part is at least a portion of a respective captured workload. In an embodiment, a first workload part is a portion of a first workload executed relative to a first capture database server and a second workload part is a portion of a second workload executed relative to a second capture database server. A portion of the first workload part and a portion of the second workload part may be replayed concurrently.

  • Publication number: 20140328791
    Abstract: Conjugates of an IL-2 moiety and one or more nonpeptidic, water-soluble polymers are provided. Typically, the nonpeptidic, water-soluble polymer is poly(ethylene glycol) or a derivative thereof. Also provided, among other things, are compositions comprising conjugates, methods of making conjugates, methods of administering compositions to an individual, nucleic acid sequences, expression systems, host cells, and methods for preparing IL-moieties.

  • Patent number: 8732126
    Abstract: A method and apparatus for capturing database system workload and replaying that workload in a database system is provided. According to one aspect, in order to subject a test database system to the same workload to which the production database system actually would be subjected, a database server in the production system captures and records workload that the database server receives from external entities. This captured workload is processed. Processes external to a database server in the test database system send the processed workload to that database server. As a result, the test database system is subjected to the same workload to which the production database system originally was subjected. The foregoing technique permits a database administrator to determine how the production database system will fare if the difference that is present in the test database system is introduced into the production database system.

  • Patent number: 8438144
    Abstract: A method, apparatus, and computer-readable medium is provided for replaying captured workload data in a database environment with connection pools. A replay system includes a dispatcher that manages a connection pool. In one aspect, the dispatcher selects available connections for sending database commands that are ready to be executed against a database, but prevents from being sent, or holds, commands that are not ready to be executed against the database. Commands may be stored at the dispatcher until the database advances to a state that allows the commands to be executed. In another aspect, the dispatcher may use an available connection to send a command to a database instance even though the command is not ready to be executed, as long as at least a threshold number or percentage of connections remains available.

  • Patent number: 8326816
    Abstract: A method, apparatus, and computer readable medium for preserving data dependency during replay of database commands without strictly preserving a global ordering of the database commands is provided. A capture process captures a workload of database commands executed by a production system. The captured workload includes object identifiers that identify database objects that were referenced directly or indirectly during execution of the database commands by the production system. The captured workload also includes an indication of whether the database objects were potentially read or written during execution of the commands. The workload is processed to determine that an object accessed during execution of a command was previously modified during execution of one or more other commands. A replay process on a test database system prevents the command from being replayed until after the one or more other commands have been replayed to modify the object.

  • Patent number: 7680960
    Abstract: A method for interworking between a first signaling network and a second signaling network is provided. The first signaling network includes a first signaling point and a signaling transfer point, and the second signaling network includes a second signaling point, the first signaling network is connected with the second signaling network via an interworking point. The method includes: receiving by the interworking point a first signaling point TransFer Prohibited message from the first signaling network; detecting all the links between the interworking point and the first signaling network, if there is any interworking link, dropping the TransFer Prohibited message; otherwise, transmitting a Signaling Unavailable message to the second signaling point. This invention also provides an interworking point of signaling networks and a communication system. In this invention, TFP message in narrowband MTP3 protocol and DUNA message the broadband M3UA protocol are combined for informing the route state.
