摘要： Provided are a computer program product, system, and method for replicating a source data set to a target data store. A point-in-time copy of the source data set is generated having a data structure identifying the data in the source data set as of a point-in-time. A restore operation is initiated to copy the source data set represented by the point-in-time copy to a restored copy of the source data set consistent with the source data set. The source data set records are transferred from the restored copy to the target data store in the target storage.

摘要： A method is described for determining whether to trigger an early commit of a micro-batch transaction. The method includes, during the micro-batch transaction, requesting access to a record using a record retrieval get record call. The method further includes receiving a response to the record retrieval get record call, and determining whether the response includes the record or a flag. The record is processed in response to a determination that the response includes the record. Additionally, in response to a determination that the response includes the flag, it is determined whether to trigger an early commit of the micro-batch transaction.

摘要： In one embodiment, a method includes determining a data node corresponding to a data record to be inserted/updated in an index structure of a record-oriented file system, creating a lock on a corresponding data node, splitting the corresponding data node sequentially into two data nodes and storing the data record in one of the two data nodes in response to the corresponding data node not having free space sufficient to store/update the data record, storing a high key of the first of the two data nodes to a parent index node, splitting the parent index node sequentially into two index nodes in response to the parent index node not having free space sufficient to store/update the high key of the first of the two data nodes, and storing the high key of the first of the two data nodes in one of the two index nodes.

摘要： In one embodiment, a process includes determining a data node for a data record to be inserted and/or updated in an index structure of a record-oriented file system. A lock on the corresponding data node is created, and the data record in the corresponding data node is stored and/or updated. However, when the corresponding data node does not have free space sufficient to store and/or update the data record, the corresponding data node is split sequentially into two data nodes. The new data record is stored in one of the two data nodes. The process continues by creating a lock on and updating a parent node in a sequence set which includes information about the corresponding data node and any parent index nodes above the parent index node which are affected by splitting the parent index node.

摘要： A computer-implemented method according to one embodiment includes establishing a predetermined checkpoint and storing a log of duplicate read data in association with the predetermined checkpoint during a running of an application that is processing at least one data set, the duplicate read data including an image of all data retrieved from the at least one data set in response to a plurality of data reads made by the application before the predetermined checkpoint; identifying a first failure of the application; and restarting the application and performing a first replay of the application in response to the first failure.

摘要： In one embodiment, a method for providing alternate keys in a keyed index includes creating a first base record in a keyed index of a database, the first base record including a first unique key and a first data record, wherein the first data record includes at least one sub key and at least one first value, each sub key being correlated with a different one of the at least one first value in a sub key/value pair, and creating one or more alternate key records in the database, each of the alternate key records including one of the at least one sub key which is correlated with the first base record and the first unique key of the first base record. The database adheres to virtual storage access method (VSAM) in some approaches. In other approaches, a number of alternate key records created is equal to a number of first sub keys in the first data record.

摘要： In one embodiment, a method includes receiving a request to perform an update on a base data set in a record-oriented file system, wherein one or more affected records within the base data set are modified by the update. Affected alternate index (AIX) records corresponding to the affected records are located, and individual record-level locks are acquired on each affected AIX record. Each of the affected AIX records is updated according to the update after acquiring the individual record-level locks on each of the affected AIX records.

摘要： In one embodiment, a system includes at least one processor and logic configured to receive a request to process data stored in one or more index records in a keyed index of a database, determine an active key range for the one or more index records, and group the one or more index records into a number of groups for parallel processing thereof. In another embodiment, a method for utilizing a keyed index includes receiving a request to process data stored in index records in a keyed index of a database, determining an active key range for the index records, wherein the active key range is determined based on any of: a type of the index records, a horizontal pointer to a next index record, and a low key value for each index record, and grouping the index records into a number of groups for parallel processing thereof.
