摘要： One system of a multisystem environment takes over log entries owned by another system of the environment. When a system owning entries on a primary log stream is inactive (or a sync point manager on the system is inactive), another system of the multisystem environment writes the log entries corresponding to the inactive system to other locations. The entries within the other locations are not owned by any system. Thus, the resource managers associated with those log entries are eligible for restarting on any system of the multisystem environment. However, all resource managers involved in a common set of transactions are to restart on the same system. The other resource managers can restart on another system. When one of the resource managers restarts on a system, the system takes back ownership of the entries associated with the common set of transactions.

摘要： A multisystem log stream of a multisystem environment is compressed. The oldest record needed for each system that can write or delete entries from the multisystem log stream is tracked, and that information is used in compression of the log stream. The block ids associated with those oldest records are maintained within a vector, and when the vector is updated, a determination is made as to whether the entry in the vector that it replaced previously contained the lowest block id in the vector. If so, all the records having block ids lower than the new lowest block id in the vector are deleted.
摘要翻译： 多系统环境的多系统日志流被压缩。 跟踪可以从多系统日志流中写入或删除条目的每个系统所需的最早的记录，并且该信息用于日志流的压缩。 与这些最旧的记录相关联的块ID保持在向量内，并且当更新向量时，确定先前替换的向量中的条目是否在向量中包含最低块id。 如果是这样，所有具有低于向量中新的最低块ID的块ID的记录将被删除。

摘要： An indicator is provided in a Page Frame Table Entry to identify a page frame as “Permanently Non-Preferred” (PNP). The indicator is set for page frames in storage subincrements which have locations corresponding to page frames determined to be “bad” (permanent errors) during system IPL, when reconfiguring storage on-line, or when a storage-related error occurs for such a frame during system execution. Mechanisms are provided to convert even PNP page frames to preferred status when shortages of preferred pages exist; but the mechanism used for choosing PNP frames, and for determining which PNP frames to convert to preferred status when conversion is needed, increase the likelihood of locating a target subincrement to use in copying pages from a preferred storage subincrement when the preferred storage is taken off-line.

摘要： Segments of storage of a computer system are shared among any number of users at varying virtual addresses. The virtual addresses can be in the same address space or different address spaces. The sharing of a segment of storage is provided by storing the real address of a page table corresponding to the segment of storage to be shared at different virtual addresses. This allows users of the same or different address spaces to share the same segment of storage by referencing the same page table.
摘要翻译： 计算机系统的存储部分在变化的虚拟地址的任何数量的用户之间共享。 虚拟地址可以在相同的地址空间或不同的地址空间中。 通过存储与要在不同虚拟地址共享的存储段相对应的页表的实际地址来提供存储段的共享。 这允许相同或不同的地址空间的用户通过引用相同的页表来共享相同的存储段。

摘要： The amount of real memory space used by descriptor tables of a computer system is reduced. On system initialization, sufficient contiguous virtual memory space for each table is allotted for descriptors in the tables to define all memory space in both central storage and expanded storage. However, only descriptors for on-line storage locations, relative to a particular partition, are placed in these tables. As the system operates, the tables are continuously updated, removing descriptors for storage locations taken off-line and adding descriptors for blocks of memory brought on-line so that the tables reflect only the storage locations then on-line in the particular partition.
摘要翻译： 计算机系统的描述符表使用的实际存储空间的数量减少了。 在系统初始化时，为表中的描述符分配了每个表的足够的连续虚拟内存空间，以定义中央存储和扩展存储中的所有内存空间。 但是，相对于特定分区，只有在线存储位置的描述符被放置在这些表中。 随着系统的运行，这些表不断更新，删除离线存储位置的描述符，并为在线提供的内存块添加描述符，以便这些表仅反映特定分区中的在线存储位置。
