2.3.4 Operands related to reduced activation
- 12) pd_start_level = 0 | 1
- This operand is applicable to a HiRDB/Parallel Server.
- Specifies whether or not reduced activation is to be used when a unit cannot be started during HiRDB startup. For details about reduced activation, see the HiRDB Version 8 System Operation Guide.
- 0:
- Do not use reduced activation. HiRDB will not start if an error prevents any unit from being activated.
- 1:
- Use reduced activation. Even if an error prevents a unit from being activated, HiRDB (all other units) will be started.
- 13) pd_reduced_check_time = wait-time-for-reduced-activation-startup-notice
<unsigned integer>((300-1200))<<1200>>(seconds)- This operand is applicable to a HiRDB/Parallel Server.
- Specifies the amount of time to wait for receipt of a notice of activation completion from each unit. If the activation completion notice is not received from a unit before the amount of time specified here elapses, reduced activation without that unit is used.
- Condition
- 1 must be specified for the pd_start_level operand.
- Specification guidelines
- Before specifying this operand, you should determine how long it takes for the KFPS01826-I message to be output after the pdstart command is entered (the KFPS01826-I message is output to the unit that defines the system manager). The value specified here must be greater than this message's output time.
- Notes
- Even when the wait time specified by this operand elapses, reduced activation cannot be executed if all the conditions for reduced activation have not been satisfied. In this case, HiRDB is abnormally terminated. For details about the conditions for reduced activation, see the HiRDB Version 8 System Operation Guide.
- 14) pd_start_skip_unit = name-of-unit-not-to-be-started[,name-of-unit-not-to-be-started]...
- This operand is applicable to a HiRDB/Parallel Server.
- Specifies the names of units that need not be started when reduced activation is executed. The units specified here are excluded from the startup process.
- Condition
- The pd_start_level operand must be set to 1.
- Advantage
- During a startup, HiRDB waits for up to 20 minutes for activation startup notifications from all units. If reduced activation is in effect, HiRDB will wait the full 20 minutes for units that cannot be started. If units that cannot be started are specified in this operand, HiRDB will not wait for activation startup notifications from them, thus saving up to 20 minutes of wait time and reducing the time for reduced activation to be implemented.
- Note
- If the standby-less system switchover (effects distributed) facility is being used, not all units within the HA group need to be active, and therefore specification of this operand is invalid. However, all back-end servers within the HA group must be running at some unit for HiRDB to be able to start.
- Even if a recovery-unnecessary front-end server unit is specified for this operand, that server unit is not treated as a reduced activation target.
