NAME : DMSUCT DESCRIPTION: Bi-Lingual mapping of UCT Control Blocks DSECT : UCTA (first) NOTES : Module Type - Macro Make sure the correct OID, SCID, and TID are in the FST returned by UCT look-up routines. The Uncommitted Change Table stores information about SFS objects that have been changed, but whose changes have not been committed. This implies the data is currently valid only for the unit of work for which the changes were made. There are two portions of the table, both of which are implemented as chains. The first is a chain of all units of work that have any UCT data associated with them. The second is the chain of data about objects that have the same unit of work. The first are called UCT Anchor blocks, and the second are called UCT Entry Blocks. |
