8.6.1 Installing and Setting Up Shunsaku Systems Including Alternative Searchers

The following diagram explains the procedure for installing and setting up Shunsaku systems including alternative searchers.

[Figure : Installing Shunsaku Systems with Alternative Searchers]

1. Perform the following operations on the director server.
   • Install the conductor, directors, and sorters
   • Set up the conductor
   • Set up directors
   • Set up sorters

   The procedure for installing and setting up Shunsaku on the director server is the same as for normal (non-cluster) systems.

   

   Refer to Installation and Setup for Systems Running Searchers on Separate Servers in the Installation Guide for more information on installing and setting up Shunsaku on the director server.

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

   The procedure for installing and setting up Shunsaku on the search server is the same as for normal (non-cluster) systems.

   

   Refer to Installation and Setup for Systems Running Searchers on Separate Servers in the Installation Guide for more information on installing and setting up Shunsaku on search servers.

3. Install the alternative searchers on search servers other than the ones that are being used normally. The procedure for installing and setting up alternative searchers is the same as for regular searchers.
4. Edit and distribute the system environment file.

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

   Edit the system environment file by adding information for the alternative searchers.

   In the alternative searcher information, add AlternativeSearcher parameters, and specify searcher identifiers for the alternative searchers, as well as their host name or IP address and the port number for receiving requests from directors.

   Specify "1" for the SearcherFailureEscalation parameter to have search servers fail over separately when errors are detected on search servers where multiple searchers are located.

Example

#--- Server information for alternative searchers---#
AlternativeSearcher  shuns1w  SchWSvr01  33501  shund1
AlternativeSearcher  shuns2w  SchWSvr02  33501  shund2
AlternativeSearcher  shuns3w  SchWSvr03  33501

#---Error recognition range in the event of a searcher error---#
SearcherFailureEscalation   1

After editing the system environment file, distribute it to all servers.

Refer to A.1 Execution Parameters in System Environment File for more information on the execution parameters in the system environment file.

• If "1" is specified for the SearcherFailureEscalation parameter, degradation processing will also be performed separately for each server.

• Place the system environment file in the following folder of all servers:

Shunsaku installation folder\etc\system

• Place the system environment file in the following folder of all servers:

/etc/opt/FJSVshnsk/etc/system

1. Start Shunsaku.

   Alternative searchers will start running in the same way as searchers operating normally when the shunsysstart command is executed.

   shunsysstart -n Shunsaku system name

   

   Refer to 3.2.1 Starting for more information on starting Shunsaku.

   

   

   Services must be registered before starting alternative searchers.
