    • A method is disclosed to debug a computer program. The method provides a computer program comprising source code, and a listing of that source code. The method further provides a computing device comprising a data storage medium, and stores the computer program in that data storage medium. The method then runs the computer program, and subsequently detects an error condition. The method creates and saves to the data storage medium a dump file comprising (N) save areas. Using information abstracted from the dump file and the source code listing, the method reproduces the source code execution at the time the error condition was detected.
    • 公开了一种调试计算机程序的方法。 该方法提供包括源代码的计算机程序和该源代码的列表。 该方法还提供包括数据存储介质的计算设备,并将计算机程序存储在该数据存储介质中。 然后该方法运行计算机程序,并随后检测到错误状况。 该方法创建并保存包含(N)个保存区域的转储文件到数据存储介质。 使用从转储文件和源代码列表中提取的信息,该方法在检测到错误条件时再现源代码执行。

    • Methods and apparatus are provided for managing data in a hierarchal storage subsystem. A plurality of volumes is designated as a storage group for Level 0 storage; a high threshold is established for the storage group; space is allocated for a data set to a volume of the storage group, storing the data set to the volume; the high threshold is compared with a total amount of space consumed by all data sets stored to volumes in the storage group; and data sets are migrated from the storage group to a Level 1 storage if the high threshold is less than or equal to the total amount of space used by all of the data sets stored to volumes in the storage group. Optionally, high threshold are assigned to each storage group and, when the space used in a storage group reaches or exceeds the high threshold, migration of data will begin from volumes in the storage group, beginning with the volume having the least free space. Thus, contention between migration and space allocation is reduced. Also optionally, when a volume is selected for migration, a flag is set which prevents space in the volume from being allocated to new data sets. Upon completion of the migration, the flag is cleared and allocation is allowed. Thus, contention between migration and space allocation is avoided.
    • 提供了用于管理分层存储子系统中的数据的方法和装置。 多个卷被指定为用于0级存储的存储组; 为存储组建立高阈值; 为数据集分配空间到存储组的卷,将数据集存储到卷; 将高阈值与存储到存储组中的卷的所有数据集的总消耗空间进行比较; 如果高阈值小于或等于存储到存储组中的卷的所有数据集的总空间量,则数据集从存储组迁移到1级存储。 可选地,高阈值被分配给每个存储组,并且当存储组中使用的空间达到或超过高阈值时,数据的迁移将从存储组中的卷开始,从具有最小可用空间的卷开始。 因此,迁移和空间分配之间的争用减少了。 另外,当选择用于迁移的卷时,设置一个标志,该标志防止卷中的空间被分配给新的数据集。 完成迁移后,该标志被清除并允许分配。 因此,避免了迁移和空间分配之间的争用。

    • A platform for and method of computer processing to support processor failover are disclosed. A plurality of computer processors are connected to an internal communication network. A virtual local area communication network over the internal network is defined and established. Each computer processor in the virtual local area communication network has a corresponding virtual MAC address and the virtual local area network provides communication among a set of computer processors but excludes the processors from the plurality not in the defined set. A virtual storage space is defined and established with a defined correspondence to the address space of the storage network. In response to a failure by a computer processor, a computer processor from the plurality is allocated to replace the failed processor. The MAC address of the failed processor is assigned to the processor that replaces the failed processor. The virtual storage space and defined correspondence of the failed processor is assigned to the processor that replaces the failed processor. The virtual local area network is reestablished to include the processor that replaces the failed processor and to exclude the failed processor.
    • 公开了一种用于支持处理器故障转移的计算机处理的平台和方法。 多个计算机处理器连接到内部通信网络。 定义并建立内部网络上的虚拟局域网通信网络。 虚拟局域通信网络中的每个计算机处理器具有对应的虚拟MAC地址,并且虚拟局域网提供一组计算机处理器之间的通信,但不排除来自多个处理器的处理器。 以与存储网络的地址空间的定义的对应关系来定义和建立虚拟存储空间。 响应于计算机处理器的故障,分配来自多个的计算机处理器来替换故障处理器。 故障处理器的MAC地址被分配给替换故障处理器的处理器。 故障处理器的虚拟存储空间和定义的对应关系被分配给替换故障处理器的处理器。 重新建立虚拟局域网,以包括替换故障处理器并排除故障处理器的处理器。
