Using parallel MERGE phases and log sorts

BMC AMI Recover allows multiple log sorts and parallel MERGE phases to run concurrently in subtasks, which can provide an improvement in recovery performance.

For each table space, the log sorts are distributed over the number of sorts specified by the MAXLSORT option (MAXLSORT integer and MAXLSORT=0). MAXLSORT also determines the number of MERGE phases that can run in parallel. When you combine index key sorts (see Using multitasking index key sorts and index rebuilds) with log sorts, the KSORTSHARE option (KSORTSHARE and KSORTSHARE=YES) determines whether BMC AMI Recover shares the key sorts among table space recoveries (MERGE phases) running in parallel.

For more information, see MAXLSORT and KSORTSHARE options.
