8.6.2 Adding Alternative Searchers

Alternative searchers can be added while Shunsaku is operating. The procedure for adding alternative searchers is as follows:

[Figure : Adding Alternative Searchers]

1. Install and set up alternative searchers.

   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.

   

   Refer to Installing and Setting Up Additional Search Servers in the Installation Guide for more information on installing and setting up searchers.

2. Edit and distribute the system environment file.

   Add AlternativeSearcher parameters to the system environment file, and specify the searcher identifiers for the alternative searchers, as well as their host names or IP addresses and port numbers. Distribute the edited system environment file to all servers. To limit the directors that each alternative searcher can use, add director identifiers to the end of the parameter specification.

   Example

   #--- Server information for alternative searchers---#
   AlternativeSearcher  shuns4w  SchWSvr04  33501  shund1
   AlternativeSearcher  shuns5w  SchWSvr05  33501  shund2
   AlternativeSearcher  shuns6w  SchWSvr06  33501

   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.

   

   

   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.

3. If host names have been specified in the system environment file without using IP addresses, specify the IP addresses and host names of the additional search servers in the following file on the director server where the conductor is located:

   

   Windows installation folder\system32\drivers\etc\hosts

   

   /etc/hosts

4. Dynamically add the alternative searchers.

   Execute the shunsyscfgedit command on all director servers to dynamically add the information for the alternative searchers specified in the AlternativeSearcher parameter in the system environment file.

   shunsyscfgedit  -n  Shunsaku system name

5. Start the alternative searchers.

   

   Before starting the alternative searchers, register the service by executing the shunsservice command on the search servers where the alternative searchers are located.

   shunsservice  -n Shunsaku system name -s  alternative searcher identifier

   Start the alternative searchers. Execute the shunsysstart command on the search servers where the alternative searchers are located.

   shunsysstart -n  Shunsaku system name
