Ordering change accumulation file data
Data extracted from log records is written to each change accumulation file in order by target table space, DSNUM, page number, and log point. Target table spaces are ordered by EBCDIC collating sequence with respect to the database name and then the table space name. For example, log record data for table space A.AB is written to the change accumulation file before the log record data for table space AA.A.
Following the log record data for each table space, log record data for the associated indexes is written in an order that corresponds to the ordering of spaces on a wildcarded image copy for the BMC AMI Recover for Db2 product. This ensures optimal use of recovery resources when you use image copies and change accumulation files in a recovery.
