Executor: Superuser

The superuser must register users who will manage HiRDB into the OS on each server machine. Table 2-1 lists the information that is to be registered.

Table 2-1 Information to be registered in OS on each server machine

Information to be registered	Format
Log-in name	1-8 alphanumeric characters beginning with an alphabetic character*
User ID	Any characters

^* None of the following words can be used: ALL, HiRDB, MASTER, or PUBLIC.

If the system switchover facility is to be used with HiRDB/Parallel Server or HiRDB/Single Server, specify the same user ID as the HiRDB administrator registered in the OS for all server machines that operate HiRDB.

Note

A password should be registered after the user ID has been registered.

The user who uses the user ID registered here to log onto the system is called the HiRDB administrator. The following privileges are granted to the HiRDB administrator:

1. Access privilege as the owner of various HiRDB system files and directories. The holder of this privilege can prohibit write operations by other users.
2. Privilege to execute the HiRDB operation commands and utilities.

Multi-HiRDB

A HiRDB administrator must be registered for each HiRDB.
