The process for activating the standby system waits for the running system to be activated. When activation of a unit in the standby system using the rapid system switchover facility takes too much time, perform the following checking procedure.
- Check to see if the running system was activated. Activate the running system if it was not activated.
- Use the pdls -d prc -a command to check to see if the pdenvcp command that is issued internally by the HiRDB in the standby system has responded. If the pdenvcp command did not respond, check to see if the _pd0envc command process remains on the running system. If this command process does remain, terminate it, then reactivate the standby system.
- Use the pdls -d rpc command to see if RPC or a file input/output process stopped the pdenvcp command that HiRDB in the running system issues internally. Eliminate the cause of the network or OS error, and then reactivate the standby system.
- If the process of activating the standby system during system switchover times out, redefine the value of the pd_system_complete_wait_time operand (completion wait time for the pdstart command). Set a value that takes into account the activation time of the standby system then reactivate the standby system. If the process for activating the standby system times out, use the pdls -d prc -a command to see if the _pd0envc command process remains on the running system. If this command process does remain, terminate the process, and then reactivate the standby system.
- When using a large number of lists, the list initialization process may increase the time required for system switchover. In such a case, consider changing the list initialization time with the pd_list_initialize_timing operand. For details about changing the list initialization time, see 13.21(9) Changes when initializing (deleted) lists.
