摘要： 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.

摘要： Described herein are methods for determining patterns based on requests received by a server. Based on the determined patterns, insight into the types of requests received by the server can be gained. Additionally, performance statistics and query statistics can be aggregated in a useful way. For example, performance statistics may be summarized for each determined pattern. One technique for determining patterns includes determining a sequence of template identifiers identifying templates that correspond to sub-sequences of requests in a sequence of server requests. A model may be created based on the sequence of template identifiers. Based on the model, template patterns may be determined. Template patterns may further be grouped into pattern clusters.

摘要： 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.

摘要： 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.
