Methods and systems are disclosed which utilize Little's law to improve cache management in a computer based storage system in which the cache is a partitioned or non partitioned write-back cache. In a first aspect, a method and system for managing a write-back cache in a computer based system to accommodate for deferred write operations is disclosed. The method. and system comprises determining an average cast out delay for a cache entry. In a second aspect the method and system comprises utilizing the average castout delay for estimating the number of dirty cache entries which will be needed by the cache if the write operations rate and the average cast out delay does not change significantly. In a third aspect, a method and system for managing a partitioned and prioritized cache in a computer based system to provide sensitivity to a local maximum is disclosed. The method and system comprises determining an average residency time for a cache entry in the cache and then determining the minimum number of clean pages which should be made available to a particular cache partition based upon that average residency time.

A system and method are provided for managing persistent and non-persistent data in a log structured disk array. In a log structured array, data are first collected in a log stored in a buffer. When the buffer is full, the data are written to a disk drive. Persistent data are continually accessed over a long period of time such that, most disk activity is associated with persistent data. Preferably, the persistent data are stored in the part of the disk where access times are minimal (active region), such as in the middle cylinders of a disk. When writing data (including during garbage collection procedure) persistent data is written to the active region and non-persistent data is written to the other regions (inactive region). The persistence of the data is monitored. Persistent data is migrated to the active region and non-persistent is migrated to the inactive region.

Methods for managing a Least Recently Used (LRU) cache in a staged storage system on a prioritized basis permitting management of data using multiple cache priorities assigned at the data set level. One method uses the signed difference between an assigned and actual hit ratio to dynamically allocate cache size to a class of data and its correlation with priority of that class. Advantageously, the hit ratio performance of a class of data can not be degraded beyond a predetermined level by a class of data having lower priority. Another method dynamically reallocates cache space among partitions asymptotically to the general equality of a weighted hit rate slope function attributable to each partition. This function is the product of the slope of a weighting factor and the partition hit rate versus partition space allocation function. Cache space is dynamically reallocated among the partitions in a direction that forces the weighted hit rate slope for each partition into equality over the entire cache.

Storage is managed in a shared electronic store (SES) by assigning storage classes (STCs) to each directory entry having a data item stored in SES. The assignments of directory entries and data elements to the respective STCs can be changed at any time by any CPC. Eventually, no free space remains in the SES cache, and then space for new directory entries and data items must be obtained by reclaiming space occupied by directory entries and associated unchanged data items. The reclaiming of SES space is controlled on a STC basis. Any specified STC may reclaim from itself or from another STC using reclaiming software/microcode in SES, which includes a reclaim vector, a reclaim counter, a queue, and reclaiming controls. The vector and counter have respective elements for all possible STCs to controls how a specified STC may reclaim space from any or all target STC. Any enabled target STC reclaims its space according to an LRU algorithm maintained by a queue for the STC.

Methods, program products, and systems for visual manipulation of database schema are disclosed. In general, in one aspect, a system can display a schema view and a data view in graphic representation in an integrated GUI on a display device. The system can display a schema in the schema view, and one or more data records in the data view. The system can receive a touch input from the display device in the schema view, or the data view, or both. In response to the touch input, the system can modify the schema, or the data records, or both. The system can update the schema view and data view substantially simultaneously to reflect the modification in the schema or data records.
