摘要： A radio receiver includes a voice-only detection mechanism that detects when the current radio station is transmitting mostly voice, and that changes the function of the receiver depending on whether or not the current radio station is transmitting mostly voice. In a first embodiment, the radio receiver mutes its audio output when the voice-only detection mechanism detects a voice broadcast, or mutes its audio output when the voice-only detection mechanism detects a music broadcast. In a second embodiment, the radio receiver changes to a different radio station when a voice-only signal is detected, or when a music signal is detected. The second embodiment preferably includes a spectrum analyzer that can store a frequency spectrum “signature” of a radio signal, and a second tuner that scans the available radio stations for a signal that matches the stored signature.

摘要： A database manager selectively caches journal entries for certain database changes based on dynamic selection criteria. Preferably, a journal disk drive is provided for storing changes to the database. Database change entries are sequentially cached in a main memory journal buffer, awaiting journal write. When a buffer is filled, its buffer contents are written to the journal disk. However, certain change operations will cause the contents of the buffer to be written to the journal disk immediately, before filling the buffer. Certain database change entries selectively cause the buffer to be written, depending on dynamic selection criteria. Preferably, these selection criteria take into account both the estimated time to recover in the event of a system crash and the current level of activity on the system. Generally, the busier the system, the more data will be cached, and vice versa.

摘要： A method and system of journal bundling that provides improved performance. In the preferred embodiment, a journal controller starts a timer to expire at a predetermined maximum time-to-wait. The journal controller then accumulates journal records in a bundle and transmits the bundle to the journal. The journal controller determines the number-of-journal-records accumulated in the bundle based on an adjustable preferred-bundle-size, which it calculates from an average-bundle-size over a history interval. If the timer expires, the journal controller writes the bundle to the journal even if the preferred-bundle-size has not been reached. By basing the preferred-bundle-size on an average-bundle-size over a history interval, the journal controller prevents rapid changes in the journal traffic-rate, which increases journal performance.

摘要： Disclosed are an apparatus, method, and program product which each provide an enhanced database engine. Access to precise values is provided while permitting unfettered access to those who are not interested in precise values. This is accomplished via an enhanced database index and indexing method. The entries of the database index are normalized to exclude precision. Individuals interested in precision can then specify precision as part of their query through use of a PRECISE keyword. Results are then filtered to account for the specified precision.

摘要： An apparatus and method includes a database journal that records journal entries. Each journal entry includes a validation value that is computed from the data and metadata for the record before it is changed. In this manner, journal entries may be applied with confidence to a record in a database. This is especially useful when minimized data journal entries are used. If the validation value of the journal entry matches the validation value computed from the data and metadata of the record that the journal entry is to be applied to, then the record before applying the journal entry is identical to the record in the original database, and the journal data may be applied to the database record. If the validation value of the journal entry does not match the validation value computed from the data and metadata of the record that the journal entry is to be applied to, the record is not the same as in the original database when the journal entry was generated. As a result, an error message is generated to indicate that an error was encountered when applying the journal entry. In this manner, the apparatus and method of the preferred embodiments automatically validate a database record before applying journal data to the record.

摘要： A protection utility for compiled data in a computer system having dynamically configurable logical partitions determines the time for rebuilding compiled data, and selectively stores data in a form not requiring rebuild to meet a pre-specified recovery time limit. If the configuration changes, the protection strategy is automatically migrated to adapt to the new configuration. Preferably, the compiled data is multiple database indexes, which are selectively logged to reduce recovery time. Logging is selectively discontinued or extended responsive to changes in partition configuration, allowing a gradual migration to the target recovery time using the new set of configured resources.

摘要： A method, memory system, and computer program product are provided for implementing lock based delayed space recycle control. The memory space recycle method is used with a memory in a computer system. A data element lock is obtained for a data record in a data block. Then an update on the data record is performed. A waiting to be recycled index for the data block is maintained. The waiting to be recycled index includes a record number, an address of the large object block (LOB) and the length of the LOB space. When the last lock on a data element is about to be released the waiting to be recycled areas associated with that data element are freed.
