Stopping and restarting Data Aggregator

 

 

Run the following to stop the Data Aggregator:

 

 

/etc/init.d/dadaemon stop

 

 

Polling continues on Data Collector if it is running and polling when Data Aggregator is stopped. Data Collector queues polled data for future delivery to Data Aggregator.

 

 

Run the following to start the Data Aggregator:

 

 

/etc/init.d/dadaemon start

 

 

Data Aggregator starts and synchronizes with CA Performance Center automatically.

 

 

When Data Aggregator starts, any queued, polled data on the Data Collector host are sent to Data Aggregator. The newest data is discarded if the queued data exceeds a disk space limit that is configured on the Data Collector system. As a result, there is a gap in the polled reporting data.

 


Stopping and restarting Data Repository

 

 

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

 

 

Follow these steps:

 

 

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.

 

 

Open a command prompt and type the following command:

 

 

/etc/init.d/dadaemon stop

 

 

Log in to the database server you use for the data repository as the database administrator user, not as the root user.

 

 

Type the following command:

 

 

/opt/vertica/bin/adminTools

 


The Administration Tools dialog opens.

 

 

Select (4) Stop Database.

 

 

Press the Space bar next to the database name, select OK, and press Enter.

 

You are prompted for the database password.

 

 

Enter the database password and press Enter.

 

The data repository database stops.

 

 

Note: If the data repository does not stop, select (2) Stop Vertica on Host from the (7) Advanced Tools Menu.

 

 

Select Exit and press Enter.

 

 

Relocate the computer, or perform any other administrative tasks.

 

 

Log in to the database server you use for the data repository as the database administrator user, not as the root user.

 

 

Type the following commands:

 

 

/opt/vertica/bin/adminTools

 

 

The Administration Tools dialog opens.

 

 

Select (3) Start Database.

 

 

Press the Space bar next to the database name, select OK, and press Enter.

 

You are prompted for the database password.

 

 

Enter the database password and press Enter.

 

The data repository database starts.

 

 

Select (E) Exit and press Enter.

 

 

Start Data Aggregator by logging 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.

 

If you installed Data Aggregator as the sudo user, you set up a sudo command alias for the /etc/init.d/dadaemon command. Use the sudo command to run the dadaemon start script.

 

 

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

 

 

Open a command prompt and typing the following command:

 

 

/etc/init.d/dadaemon start

 

 

The data repository restarts.

 


Stopping and restarting Data Collector

 

 

To stop the Data Collector run the following command:

 

 

/etc/init.d/dcmd stop

 

 

When Data Collector is stopped, all ongoing polling stops. You cannot run any discoveries.

 

 

To start the Data Collector run the following command:

 

 

/etc/init.d/dcmd start

 

 

When Data Collector is restarted, scheduled polling resumes. You can resume running discoveries. Data Collector resynchronizes with CA Performance Center automatically.
