Abstract: In a computer having one or more secondary storage devices attached thereto, a Finite Data Environment Processor (FDEP) manages Data Sets residing on the secondary storage devices and in memory using Set Lists (SLs) and General Record Pointers (GRPs). The Data Sets contain either data or logical organizational information. The Set Lists comprise Data Sets organized into a hierarchy by listing a identifier for each of the data sets with a corresponding identifier for the logical parent of that data set. These set lists are also data sets and can be identified as child or parent in a set list. The General Record Pointers identify information in terms of Data Sets and records within them. Using the principal idea that a Data Set is uniquely identifiable, the present invention eliminates problems normally associated with referencing the location of data after the data has been moved.

Abstract translation: 在具有连接到其上的一个或多个辅助存储设备的计算机中，有限数据环境处理器（FDEP）使用集合列表（SL）和通用记录指针（GRP）来管理驻留在辅助存储设备上和存储器中的数据集。 数据集包含数据或逻辑组织信息。 集合列表包括通过列出每个数据集的标识符与该数据集合的逻辑父节点的对应标识符来组织成层次结构的数据集。 这些集合列表也是数据集，可以在集合列表中标识为子节点或父节点。 一般记录指针根据数据集和其中的记录识别信息。 使用数据集唯一可识别的主要思想，本发明消除了在数据移动之后参考数据位置通常相关的问题。

Abstract: A computer-executed method permits one or more of the following three functions to be performed on a DB2 data table: (1) dynamically altering (replacing) the EDITPROC parameter in the DB2 catalog definition of the DB2 data table, without the necessity of unloading the data from the table; (2) dynamically adding an EDITPROC to an existing DB2 data table whose DB2 catalog definitional information does not include an EDITPROC parameter; and (3) dynamically adding a column (field) to an existing DB2 data table that already includes an EDITPROC. The method does not make the assumption, made by IBM's DSNUTILB utility program, that the DBD records for a given database are untrustworthy and that all definitional information therefore must be verified. The method makes use of code to trick DB2 into bringing certain definitional information for the data table in question, including the DBD and OBD records, into memory from DASD (disk) storage. The method also makes use of a swapping routine which provides a dynamic procedure for exchanging DBD and OBD information between the DB2 table to be modified and a shadow DB2 table which already contains the modified DBD and OBD information.

Abstract translation: 计算机执行的方法允许在DB2数据表上执行以下三个功能中的一个或多个：（1）在DB2数据表的DB2目录定义中动态地更改（替换）EDITPROC参数，而不需要卸载 表中的数据; （2）动态地将EDITPROC添加到其DB2目录定义信息不包括EDITPROC参数的现有DB2数据表中; 和（3）动态地将列（字段）添加到已经包含EDITPROC的现有DB2数据表中。 该方法不会由IBM的DSNUTILB实用程序做出假设，给定数据库的DBD记录是不可信赖的，因此必须验证所有定义的信息。 该方法利用代码来欺骗DB2将有关数据表（包括DBD和OBD记录）的某些定义信息带入DASD（磁盘）存储器的内存中。 该方法还使用交换例程，该例程提供用于在要修改的DB2表和已包含修改的DBD和OBD信息的影子DB2表之间交换DBD和OBD信息的动态过程。

Abstract: A method and system for updating data stored on a computer storage device are provided. The data is contained in records or entries. Each record or entry has a primary pointer and an indicator. The indicator initially has each bit set to a predefined bit value. When data is to be updated (and thus, the record or entry containing the data is to be superseded), at least one bit of the indicator is changed from the predefined bit value to another bit value to point to the new record or entry and to indicate that the data in the new record or entry is an update of the data in the superseded record or entry. This method and system are especially suitable to be used in a write-once computer storage device.

Abstract translation: 提供了一种用于更新存储在计算机存储设备上的数据的方法和系统。 数据包含在记录或条目中。 每个记录或条目都有一个主指针和一个指示符。 指示器最初将每个位设置为预定义的位值。 当要更新数据（因此，包含数据的记录或条目将被替代）时，指示符的至少一个位从预定义位值改变为另一个位值以指向新的记录或条目，并且 以指示新记录或条目中的数据是取代的记录或条目中的数据的更新。 该方法和系统特别适用于一次写入计算机存储设备。

Abstract: A method is described for managing data records stored in non-volatile memory in a disk drive system with cache memory. A variable-length directory containing descriptors of disk records is used to locate a selected record non-volatile memory. A table, ordered sequentially by record number, is used to quickly locate a record in non-volatile memory without having to perform a time-consuming search. In order to efficiently utilize space in non-volatile memory, a list is kept of free space for storing record descriptors. After an initial nominal allocation, additional free space is allocated only when required, thus further increasing the efficiency of use of non-volatile memory.

Abstract: A peripheral data storage hierarchy includes three storage levels. The top storage level is a fast accessing direct access storage device(s), such as magnetic disk drives. The intermediate level is an automatic warehouse type library, storing a large plurality of optical disks, which are automatically transferred between storage cells of the library and optical disk drives operatively connected to the host processor. The bottom level of the storage hierarchy includes one or more stand-alone optical disk drives and a shelf unit. Personnel manually carry the optical disks between the stand-alone drives and the shelf unit upon mount and demount commands received from the host processor. The intermediate library level uses the same type of optical disk as used in the bottom level of the data storage hierarchy. An I/O station in each of the automatic libraries enables manual access to the optical disk for transferring the optical disks between the intermediate and bottom levels. Preferably, the transfer is only from the intermediate level to the bottom level. Access to named storage objects in disks stored in the bottom level are through the stand-alone drives. A host processor has an independent access path to each level of the data storage hierarchy. A directory and other data structures indicate the number of copies made of each named data object and the location of such copies, such that the host processor 10 can independently access a copy from any level of the data storage hierarchy.

Abstract: A memory assignment method used with a disk file management system operating with a hard disk memory wherein data is stored in appropriate ones of a number of discrete files on the disk, and each file has an assigned amount of memory space exclusively associated therewith for the storage of data that should be in the file. The disk file management system keeps track of how much of the memory dedicated to the exclusive use of each file on the disk is yet available for the storage of data in each file, and also keeps track of how much of the memory on the disk is yet available for storage but has not yet been assigned to the exclusive use of any particular file. When the system determines that the amount of not yet used memory dedicated to the exclusive use by a file for the storage of data has reached a predetermined low level the system automatically takes a predetermined amount of memory not yet assigned to the exclusive use of any file and transfers it to the exclusive use of the file with the low level of not yet used memory.

Abstract: Deletion of a particular message in a file unit is accomplished for those messages with deletion set code in a file directory displayed on a screen. Operation of the deletion of a message includes (a) depression of a "deletion" key for indicating a file directory on a screen, (b) designating messages to be deleted by depression of a deletion set/reset key to change a deletion set/reset code to a set code, and (c) execution of deletion by the depression of a "deletion execution" key to delete a message with said deletion set code. A file directory indicated on a screen includes a deletion set/reset code, a message number, nature of a message, length of a message, and first 60 characters of a message, which simplifies identification of a message to be deleted.
