Starting the system

If your system includes crawlers, you must start the crawler sessions. The servers for processing documents, building the index, and processing query requests start automatically when there is data available to parse, analyze, index, or query.

To start the system:

1. Log in as the default Watson Explorer Content Analytics administrator and start the system components:

   esadmin system startall

   This command starts all of the system components and sessions, such as:

   • The CCL on the computer where you run the command, if the CCL is not already running
   • The database network server on the crawler server
   • The ESAdmin session for the administration console on the master server
   • Search applications and the content analytics miner on the search servers
2. Start the administration console and log in as the administrator. If you use administrative roles, you can log in as a collection administrator or operator who has authority for the collection that you want to start.
3. On the Collections view, expand the collection that you want to administer.
4. In the Crawl and Import pane, click an icon to start a specific crawler or click the icon to select multiple crawlers and start them at the same time.
   • If you start a Web crawler, the crawler begins crawling data immediately. These types of crawlers run continuously to crawl and recrawl Web documents.
   • If you start one of the other crawler types, the crawler session starts. The crawler begins crawling documents according to the action that you selected in the crawler properties (a full crawl, all updates, or only new and modified documents). You can control the type of crawl that is done by editing crawler properties, configuring a crawler schedule, or monitoring details about the content crawled by a specific crawler.

     After the crawler starts, you can let it run continuously. If you scheduled the crawler, the crawler will run again at the scheduled dates and times.
