The current limit of the regulator may be adjusted using digital circuits, such as a counter and a digital to analog converter, or analog circuits using a pulsed current source, for example. The slew rate may be controlled to exceed a target slew rate or to stay within a range of slew rate limits. | 09-25-2008 |

20090106262 | SCRUBBING AND EDITING OF DIAGNOSTIC DATA - Techniques that enable a user or customer at a system site to review and, if desired, modify data identified at the system site for transmission to a diagnosis site prior to the transmission. The identified diagnostic data may be modified such that data that the user does not want to be sent to the diagnosis site (e.g., sensitive data) is excluded from the data communicated to the diagnosis site. The data may be modified by removing or excluding the sensitive data from the data that is communicated to the diagnosis site or replacing the sensitive data with non-sensitive data. The modified data may then be communicated from the system site to the diagnosis site in the form of a package. | 04-23-2009 |

In one embodiment, a health monitor infrastructure is provided that is configured to perform one or more health checks in a monitored system for diagnosing and/or gathering information related to the system. The one or more health checks may be invoked pro-actively on a scheduled basis, reactively in response to a condition detected in the system, or may even be invoked manually by a user such as a system administrator. | 04-23-2009 |
20110276550 | FINE GRAIN SYNCHRONIZATION FOR DATABASE REPLAY - 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. | 11-10-2011 |
20110295801 | FILTERING WORKLOAD FOR DATABASE REPLAY - 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. | 12-01-2011 |
