摘要： A method and system are provided for conducting a cluster software version upgrade in a fault tolerant and highly available manner. There are two phases to the upgrade. The first phase is an upgrade of the software binaries of each individual member of the cluster, while remaining cluster members remain online. Completion of the first phase is a pre-requisite to entry into the second phase. Upon completion of the first phase, a coordinated cluster transition is performed during which the cluster coordination component performs any required upgrade to its own protocols and data structures and drives all other software components through the component specific upgrade. After all software components complete their upgrades and any required data conversion, the cluster software upgrade is complete. A shared version control record is provided to manage transition of the cluster members through the cluster software component upgrade.

摘要： There is provided, in a computer processing system, an apparatus for managing object data. The apparatus includes a changed objects manager for creating and managing a changed objects list that at least identifies the objects that have changed based on time of change. The changed objects list is associated with a plurality of time buckets. Each of the plurality of time buckets is associated with a respective date and time period and with object change records for objects having a timestamp falling within the respective date and time period. Each of the object change records is associated with a unique object identifier and the timestamp for a corresponding one of the objects. The timestamp specifies a date and a time corresponding to a latest one of a creation time or a most recent update time for the corresponding one of the objects.

摘要： A method and system for efficiently determining compatibility between a server node and a shared resource. The system includes a version control record that organizes metadata relating to the cluster and to data within the shared resource into a searchable format. A server node joining the cluster accesses the version control record at a known location (102). Prior to joining the cluster, the server node will use the version control record to determine compatibility with the disk header version (104), compatibility with the control record version (110), and compatibility with each data item in the version control record (112). In addition, the system may be used as a control mechanism for upgrades to system resources for existing cluster members.
摘要翻译：一种用于有效地确定服务器节点和共享资源之间的兼容性的方法和系统。该系统包括版本控制记录，其将与集群相关的元数据和共享资源内的数据组织为可搜索的格式。加入集群的服务器节点在已知位置访问版本控制记录（102）。在加入群集之前，服务器节点将使用版本控制记录来确定与磁盘头版本（104）的兼容性，与控制记录版本（110）的兼容性，以及与版本控制记录中的每个数据项（112）的兼容性）。此外，该系统可以用作用于升级现有集群成员的系统资源的控制机制。
