3.2.1 Starting Shunsaku

The procedure used to start Shunsaku is explained below.

Use the procedure to start sort servers, search servers, any additional director servers, and the director server where the conductor is located.

[Figure : Shunsaku Start Procedure]

*1) A search server connected to an additional director server.
*2) A search server connected to a director server where the conductor is located.

Execute the shunsysstart command on sort servers, search servers, any additional director servers, and the director server where the conductor is located.

To start Shunsaku, execute the shunsysstart command on all servers in the same way.

shunsysstart -n Shunsaku system name

The following explanation applies when a multi-server configuration is in place. Users of systems that operate on a single server or systems in which searchers run on separate servers should only read the sections relevant to their configuration.

Note the following points when starting additional director servers, search servers, and the director server where the conductor is located:

• When directors start up, they become available only after all of the searchers defined by the Searcher parameter in the system environment file have finished starting up, and the distribution of director data has completed.

  However, if degradation has been performed before a director starts up, the number of searchers that will be available when the director starts depends on how many searchers have produced abnormalities, as follows:

  • If only some searchers have produced abnormalities

    The number of searchers that were connected last time the director stopped

  • If all searchers have produced abnormalities

    The number of searchers that are registered to the relevant directors

• If the searcher degradation is controlled, the following procedures are necessary to recommence the operation after an error with searcher occurs.
  • If the degradation cannot be performed, start the searchers with the minimum number of searchers that can be started (Number of all searchers - number of searchers specified by the DegradableSearcherCnt parameter). Then start the director to recommence an operation.
  • If the degradation is performed and the number of malfunction searchers is less than the number of searchers specified at the DegradableSearcherCnt parameter, it is possible to start the director and continue the operation.

  Refer to A.1 System Environment Files and A.3 Director Environment Files for more information on the DegradableSearcherCnt parameter.

• When searchers start up, they access the director defined in the system environment file. If the director has not begun starting up, searchers will try to access the director at one-second intervals.
• Start the director server where the conductor is located after other servers have finished starting up.
• Data cannot be imported, searched, updated, sorted, or aggregated until all directors, searchers, sorters, and the conductor have finished starting up.

• Before the directors, searchers, sorters, and the conductor can be started, they must be registered with the service.

  Refer to the Installation Guide for more information on registering directors, searchers, sorters, and conductors with the service.
