4.2.2 Adding Directors and Director Servers

Extra directors must be added if there are more searchers that can be managed by a single director.

Directors can be added to an existing director server. However, in order to handle large amounts of data and improve performance, it is also possible to add a new director server.

Director servers can be added while the Shunsaku system is operating.

Refer to Systems that operate with additional director servers in Server Configurations in Chapter 2, Design for more information on server configurations.

[Figure : Procedure for Adding Director Servers]

Use the following procedure to add director servers.

1. Install and set up the directors on the director server being added.

   

   There is no need to install or set up a conductor or sorter when adding a director server.

   If a director is to be added without adding a director server, the director does not need to be installed. It is sufficient to simply set up the director.

   

   Refer to Installation and Setup with Additional Director Servers in Chapter 3, Shunsaku System Installation and Setup of the Installation Guide for more information on installing directors.

2. Install and set up the searchers on the search server being added.

   

   Refer to Installation and Setup with Additional Search Servers in Chapter 4, Shunsaku System Installation and Setup of the Installation Guide for more information on installing searchers.

3. Edit the system environment file on the director server where the conductor is located, and distribute it to the additional servers.

   Edit the system environment file by adding the following execution parameters:

   Execution parameter name	Meaning	Explanation
   Director	Server information for directors	Add information for directors on the director server being added
   Searcher	Server information for searchers	Add all of the information for searchers on the search server being added

   

   

   • Distribute the system environment file to the "\etc\system" folder in the Shunsaku installation folder on all servers.

   

   • Distribute the system environment file to the /etc/opt/FJSVshnsk/etc/system directory on all servers.
4. Execute the shunsysstart command on the additional search server and director server to start the searchers and directors.

   shunsysstart -n Shunsaku system name

   
   
5. Edit the conductor environment file on the director server where the conductor is located.

   Add the following execution parameters:

   Execution parameter name	Meaning	Explanation
   File (*1)	File information	If Shunsaku File is used, add File information for the directors being added.
   Domain (*1)	Domain information	Edit this information if a new File is being created and the newly created File is to be included in a Domain
   InsertPoint	Information for the director where data is to be inserted	If multiple directors are to be used without using Files, specify the director where data from APIs is to be inserted. If Files are to be used, specify the director where data from APIs is to be inserted for each File on which multiple directors have been registered.

   *1) Specify this parameter only when Shunsaku File is used.

6. If host names have been specified in the server information for directors and server information for searchers without using IP addresses, specify the IP addresses and host names of the additional director servers in the following file on the director server where the conductor is located.

   

   Windows installation folder\system32\drivers\etc\hosts

   

   /etc/hosts

   

   This procedure is not required when adding directors to the director server where the conductor is located.

7. Execute the shunsyscfgedit command on the director server where the conductor is located in order to reflect the additional director information on the conductor.

   Newly added directors are enabled after the shunsyscfgedit command has been executed.

   shunsyscfgedit -n Shunsaku system name
