Stop and Restart Data Repository

Situations can arise when you must stop and restart Data Repository. For example, the computer where Data Repository is installed can lose power or can lock up. Or, you want to relocate the computer. In this case, stop and restart Data Repository. If you want to install an operating system patch or you want to upgrade to a new version of Data Repository, stop and restart Data Repository.

Follow these steps:

1. Log in to the computer where Data Aggregator is installed. Log in as the root user or a sudo user with access to a limited set of commands.

   Note: For more information about the sudo user, see the Data Aggregator Installation Guide.

2. Open a command prompt and type the following command:

   service dadaemon stop
   

3. Log in to the database server you use for Data Repository as the database administrator user, not as the root user.

Stop and Restart the ActiveMQ Broker

Restart the Apache ActiveMQ broker if Data Aggregator detects a problem with ActiveMQ and Data Aggregator is unable to restart the broker successfully. You can also manually stop and restart the service when needed.

Follow these steps:

1. Open the following directory from the command line:

   cd da_install_dir/broker/apache-activemq-version/bin
   

   da_install_dir

   Specifies the location of the Data Aggregator installation directory.

   apache-activemq-version

   Specifies the version of Apache ActiveMQ.

   Example: apache-activemq-5.5.1b

2. Run the stop command:

   ./activemq stop -jmxurl service:jmx:rmi:///jndi/rmi://localhost:11099/jmxrmi --jmxuser admin --jmxpassword activemq da_broker
   

   –jmxurl service:jmx:rmi:///jndi/rmi://localhost:11099/jmxrmi

   Specifies the location of the activemq broker. This location only changes when a user modifies the port, or a user externalizes the broker to another system.

   Note: Modifying the port number is supported, but we do not support externalizing the broker.

   --jmxuser admin

   Specifies the username for shutting down the service.

   Default: admin

   --jmxpassword activemq

   Specifies the password for shutting down the service.

   Default: activemq

   da_broker

   Specifies the broker name that will be shut down.

   Default: da_broker

3. Run the start command:

   ./activemq start
