HiRDB automatic startup means that HiRDB starts automatically when OS starts. Manual startup means that the pdstart command is entered after OS has started to start HiRDB. Which startup method is to be used is specified in the pd_mode_conf operand of the system common definition.

When automatic startup is specified, HiRDB (the unit) restarts automatically, even after HiRDB (the unit) has terminated abnormally. However, if three restart attempts in a row result in abnormal termination, there are no more attempts to restart the system automatically.

Reference note

• If HiRDB terminates abnormally during its startup or termination processing, the next startup will have to be by manual startup.
• A startup mode (forced startup, unit-basis startup, server-basis startup) that involves specification of pdstart command arguments (options) cannot be specified when startup is by automatic startup.
