A different HiRDB administrator must be registered for each HiRDB. For details about registering a HiRDB administrator, see 2.1.2 Registering the HiRDB administrator.

1. To install a HiRDB at the server machine where HiRDB has already been installed by the standard setup method, select Setup with Identifier during installation and specify the setup identifier. A setup identifier is a string of 1-4 alphanumeric characters (case sensitive) including no space that is unique within a single server machine.
2. A setup identifier is specified to identify a HiRDB environment.
3. Specify a different installation directory for each HiRDB to be installed.
4. HiRDB 05-05 or a later version allows multiple HiRDBs to be installed. Do not mix these versions with HiRDB 05-04 or a earlier version.
5. You cannot mix a HiRDB/Single Server with a HiRDB/Parallel Server.
6. To use a product that does not support multi-HiRDB, you need to select the standard installation method (format with no setup identifier) for the HiRDB.

For details about how to install HiRDB, see 2.2 HiRDB installation procedure.

If you install a HiRDB specifying a setup identifier, you need to specify the communication port's service name and service number in the SERVICES file before starting HiRDB services. The following shows the procedure from selection to specification of the communication port's service name and service port number.

(a) Checking the system configuration

Determine the service name and service port number for the communication port that are the same in the HiRDB system and that are unique within the server machine.

(b) Registering the service port number in the OS

In the SERVICES file (under %windir%\system32\drivers\etc), register the communication port's service name and service port number determined in (a) previously that are the same in the HiRDB system and that are unique within the service machine.

(c) Changing the communication port's service name

Specify the communication port's service name, registered in (b) previously, for each unit. For the units in the HiRDB server, use the same service name and service port number for the communication port. To specify the service port number, use the pdntenv command.

Immediately after the installation, the system assumes pdrshsrv as the communication port's service name if you have used the standard setup method and pdrshsrv with the setup identifier if you have specified the setup identifier. Figure 10-1 shows an example of a service name and service port number for the communication port when a multi-HiRDB consists of a HiRDB/Parallel Server installed by the standard setup method and another HiRDB/Parallel Server installed with a setup identifier (P001) specified.

Figure 10-1 Example of service name and service port number for communication port

Explanation:

1. Specify the communication port's service name pdrshsrv and service port number 29999 in the SERVICES file.
2. Use the pdntenv command to change the communication port's service name to pdrshsrv for the HiRDB/Parallel Server with setup identifier P001.
