- 11) 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
- Parallel input/output processing is not performed for regular files.
- Specification guidelines
- The value to be specified depends on the file type:
| Condition |
Specification guideline |
| Character special files |
There are at least 10 character special files (per server) that define RDAREAs |
10 |
| There are fewer than 10 character special files (per server) that define RDAREAs |
Number of character special files |
| Regular file |
1 |
- 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.
