3.3.4 Operands related to full recovery processing
- 10) pd_max_recover_process = concurrently-executable-full-recovery-processes-count
<unsigned integer>((1-10))- Specifies the number of processes to be recovered during full recovery processing. For a HiRDB/Parallel Server, this operand specifies the number of processes to be recovered per server (dictionary server or back-end server).
- Condition
- You need to use the raw I/O facility.
- Specification guidelines
- There are three or more logical volumes for which an RDAREA is defined (per server): 3
- There are fewer than three logical volumes for which an RDAREA is defined (per server): Number of logical volumes
- Increasing the value of this operand increases the input/output concurrency during full recovery processing, and thus can shorten the recovery time. However, because a number of processes equaling value-of-this-operand
server-count are started, determine a value by taking the aforementioned specification value guideline and HiRDB resources into consideration.
