  • Publication number: 20230315585
    Abstract: Described systems and techniques enable log recovery that spans inter-tablespace movement of one or more tables within a database. Log-related processing, including, e.g., system recovery, auditing, or reporting, may be maintained, even when such inter-tablespace table movements occur within a time window defined for the log-related processing. A table movement of a moved table from a source tablespace to a target tablespace within a database may be identified. Within a plurality of log records of the database, pre-move log records identifying the moved table as being included within the source tablespace may be identified, and post-move log records identifying the moved table as being included within the target tablespace may be identified. The pre-move log records may be updated to obtain updated pre-move log records identifying the moved table as being included within the target tablespace.

  • Patent number: 8595190
    Abstract: In one general aspect, an apparatus can include a completion identifier configured to identify, for completion processing, a large object (LOB) deleted from an auxiliary table within a DB2 database environment based on a space map record associated with the large object where the auxiliary table functions as an auxiliary space to a base table. The apparatus can also include a completion analyzer configured to identify a resource where an image of the large object is stored at a time before the deletion of the large object from the auxiliary table.

  • Patent number: 8121992
    Abstract: A mechanism works in conjunction with a DB2® Log and an analysis tool, such as BMC's Log Master™, to handle logged data for Large Objects (LOBs) stored in tables of a DB2 database system. A plurality of controls track data logged for the LOBs. The mechanism reads log records from a DB2 Log and uses the controls to determine which of the tracked LOBs is associated with the log records and obtains data from those associated log records. The mechanism builds keys to index the data and stores the keys and the data in a Virtual Storage Access Method store having Key Sequenced Data Sets maintained separate from the log record store for the DB2 Log. When requested by the analysis tool, the data in the store can be reassembled using the keys and map records in the first store that map the logged data for the tracked LOBs.
