This section provides notes on errors during unit startup. You should consult this section when the following conditions are applicable.
All of conditions 1, 2, and 3 or all of conditions 1, 2, and 4 must be satisfied:
When a unit is started, HiRDB starts all servers at the unit concurrently. If an invalid system definition operand is detected or an error occurs in one of the servers, startup of the entire unit fails. In such a case, the following events may occur:
In such a case, HiRDB allocates a new current file the next time unit startup is performed. The current file allocated during the previous unit startup is closed (it is not reused). The HiRDB administrator must take one of the actions described below in order to reallocate this closed system log file as the current file.
After executing pdlogunld or pdlogchg for the corresponding system log file, one of the actions listed below can be taken, depending on HiRDB's activity status:
HiRDB's activity status | HiRDB administrator's action |
---|---|
During HiRDB operation | Execute the pdlogopen command on the corresponding system log file. |
Before normal startup of unit | No action is required. This file is identified as the available current system log file during unit startup. |
Before unit restart | After the unit is restarted, execute the pdlogopen command on the corresponding system log file. |
