This article explains how to start a database.

Prerequisites

There are no prerequisites for this procedure.

Procedure

This procedure uses the c4 and confd_client command-line tools in a Linux terminal. For more information about these tools, see Exasol Deployment Tool (c4) and ConfD.

  1. Connect to the cluster operating system (COS) using c4 connect -i PLAY_ID -s cos.

    Example:
    Copy 
    ./c4 connect -i c3275f84 -s cos

    For more information about how to use c4 connect, see How to use c4.

  2. To find the database name when you are connected to COS, use the ConfD job db_list.

    Example:
    Copy 
    confd_client db_list
    - MY_DATABASE

  3. To start the database, use the ConfD job db_start with the db_name parameter:

    Example:
    Copy 
    confd_client db_start db_name: MY_DATABASE

Verification

To verify that the database is running, use the ConfD job db_state.

Example:
Copy 
confd_client db_state db_name: MY_DATABASE
...
Result:
'running'
