The Database Configuration screen enables you to create and configure databases using the embedded HyperSQL server or connect to an external MySQL or Oracle database. You can also create and restore database backups, as well as port existing backups to a different type of database. For example, you could back up a HyperSQL database, then re-create it as an Oracle or MySQL database. Or, you could capture the current state of a database and use that for a rollback. 

Choose Database Configuration from the administration drop-down menu (gear icon) to open the Database Configuration screen.

In this section:

Connecting to an Existing Database

  1. Choose the database software from the Type drop-down menu.
  2. Specify the settings for connecting to your database. See Database Settings.
  3. Click Test Connection to verify the settings. Contact your database administrator if you have trouble using the settings you specified.
  4. Click Save to complete the configuration.

Creating a New Database

  1. Click Create Database in the Database Connection Settings section. 
  2. Choose the database software from the Type drop-down menu.
  3. Specify the settings for connecting to your database. See Database Settings. Alternatively, you could create a database from a backup file (see to Creating a Database from a Backup).
  4. Enable the Create a new user option if you want to create a new user with access to the database.
  5. Click Create 

Creating a Backup

  1. Click Backup Database in the Database Connection Settings section.
  2. Click the file link when prompted to download the backup file.

Backing Up Databases with Large Files (MySQL Only)

If you are using a MySQL database and the backup fails, try increasing the MySQL size limits as follows:

  1. Find the my.cnf/my.ini file for your installation of MySQL. For MySQL 5.7, see http://dev.mysql.com/doc/refman/5.7/en/option-files.html. For other versions, see the appropriate manual at http://dev.mysql.com/doc/index.html.
  2. Edit the file to use the parameter settings outlined below.
  3. Restart the MySQL Service 

[mysqld]

[mysql]

[client]

Creating a Database from a Backup

  1. Click Create Database in the Database Connection Settings section.
  2. Specify information about the new database  
  3. Browse for a backup file In the Create from Backup File section and click Create.

A new database will be created in the specified location  then it will be populated with the data saved in the backup file. After a new database is successfully created, CTP will ask you if you want it to delete the previous database (the database whose connection settings are shown in the main page behind the dialog).

Adding Multiple Databases

To add multiple databases of the same type, specify a different location (e.g., schema, SID, service name, or path) when creating a new database. This prevents the existing database from being overwritten. 

To port a database to a different database type, select the target database type, then specify the desired location for the new database.

To create a new database account from this interface, enter the desired username and password, check Create a new user, then confirm the password. For new accounts on Oracle, you can also specify a data tablespace and temp tablespace—or you can leave those fields empty to use the defaults (<USER>_DATA> and <USER_TEMP>).

Current Configuration

You can view the current database configuration in this section. 

Database Table Limits

Messages received by CTP's underlying Virtualize server are logged in the database. The event message, payload, hit statistics, and time information are stored. You can change the number of event messages and entries about each hit to the server in this section.
