Page History

The Database Configuration screen enables you to create and configure databases using the embedded HyperSQL server or connect to an external MySQL or Oracle , supported database. You can also create and restore database backups, as well as port existing backups to a different type of database.  For 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. . See System Requirements for details about supported database versions and requirements.

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

4. Click Test Connection to confirm that it is correct.
   

   Info
   For MySQL databases, the root user must have the GRANT OPTION privilege.

5. Click Next.

Database Backups

Creating a Database Backup

Anchor
BackUpDatabase BackUpDatabase

To back up your CTP database, click Back Up Database on the Database Configurations page. What happens next depends on your database type:

• If the database is HyperSQL, MariaDB, or MySQL, the backup will begin immediately.

• If the database is Oracle, a dialog will appear asking for the data tablespace. Enter the name of the tablespace and click Create Backup and the backup will begin.

• If the database is PostgreSQL, a dialog will appear for the schema. Enter the name of the schema and click Create Backup and the backup will begin.

Once the backup is complete, you can click Download to download it to your device.

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 http8, see https://dev.mysql.com/doc/refman/58.70/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

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.
   Image Removed

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 (for example, schema, SID, service name, or path) when creating a new database. This prevents the existing database from being overwritten. 

• HyperSQL: Enter a new file path.
• MySQL: Enter a new schema.
• Oracle: Enter a new SID or service name.

Image Removed

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, enable 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 limit the number of event messages, entries about each hit to the server, and days of hit summary in this section.

Note that Virtualize hit statistics row is set to 100,000 by default. This affects the number of individual rows of statistics data at the bottom of the Service Virtualization Hit Statistics report. Increasing this limit beyond 1,000,000 is not recommended since performance decreases as the table size increases.

The Virtualize hit summary days limit prevents the database from growing out of control. The number of days of summary data also effects performance, but to a lesser degree than the number of Virtualize hit statistics rows.

Database Settings

See System Requirements for details about supported database versions and requirements.

HyperSQL Settings

CTP ships with an embedded HyperSQL database. To use it, choose File path as the connection mode.

• JDBC URL:  Specify the JDBC URL used to connect to your database. Example JDBC URL:
  jdbc:hsqldb:file:/hsqldb/em;ifexists=true
• Username: Specify a user that will be able to access to the database. Default is the em user. If the Create a new user option is enabled, a new user with the name specified in this field will be added to the database.
• Password: Specify the password for the user that will be able to access the database. Default is the password for the em user. If the Create a new user option is enabled, a new user with the password specified in this field will be added to the database. 

MySQL and MariaDB Settings

• JDBC URL: Specify the JDBC URL used to connect to your database. Example JDBC URLs:
  jdbc:mariadb://hostname:3306?useUnicode=true&characterEncoding=UTF-8&sessionVariables=sql_mode=NO_BACKSLASH_ESCAPES
jdbc:mysql://hostname:3306?useUnicode=true&characterEncoding=UTF-8&sessionVariables=sql_mode=NO_BACKSLASH_ESCAPES&useSSL=false&allowPublicKeyRetrieval=true
• Username: Specify a user that will be able to access to the database. Default is the em user. If the Create a new user option is enabled, a new user with the name specified in this field will be added to the database.
• Password: Specify the password for the user that will be able to access the database. Default is the password for the em user. If the Create a new user option is enabled, a new user with the password specified in this field will be added to the database.

Oracle Settings

• JDBC URL: Specify the JDBC URL used to connect to your database. Example JDBC URLs:
  jdbc:oracle:thin:@//hostname:1521/service_name
jdbc:oracle:thin:@//hostname:1521:sid
jdbc:oracle:thin:@(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=hostname)(PORT=1521))(CONNECT_DATA=(SERVICE_NAME=service_name)))
• Username: Specify the name of the schema (database) that should contain the data. Default is em.
• Password: Specify the password for the user that will be able to access the database. Default is the password for the em user. If the Create a new user option is enabled, a new user with the password specified in this field will be added to the database.

DatabaseFromBackup DatabaseFromBackup

You can create a new database from a backup. This process creates a new database and populates it with data from a backed-up database; do not attempt to use it to overwrite an existing database. Use a database backup from the same version of CTP; you should not attempt to create a new database using a backup from a different version of CTP.

1. Click Restore Database.
2. Choose one of the following options and enter the database and user information as described:
   • Create new CTP database, user, and schema
     1. Choose a database type: HyperSQL, MariaDB, MySQL, Oracle, or PostgreSQL.
     2. Enter the database URL and root credentials.
     3. Click Test Connection to confirm that it is correct.
        
     4. Click Next.
     5. Enter new user and credentials and click Next.
   • Create CTP database schema
     1. Choose a database type: HyperSQL, MariaDB, MySQL, Oracle, or PostgreSQL.
     2. Enter the database URL and user credentials.
     3. Click Test Connection to confirm that it is correct.
     4. Click Next.
3. Click Browse and navigate to the backup file. When the backup has finished uploading, click Restore Database.

A new database will be created in the specified location then it will be populated with the data saved in the backup file.

Migrating a Database

You can migrate a database from one type to another (for example, from HyperSQL to PostgreSQL). Doing so is a basic two-step process:

1. Create a backup of your existing database. See Creating a Database Backup.
2. Restore your backup to the new database type. See Creating a Database from a Backup.

You should only do this within the same version of CTP. Keeping with the HyperSQL-to-PostgreSQL example from before, you want to create the backup of your HyperSQL database in the same version of CTP as your PostgreSQL database. Doing something like backing up your HyperSQL database in a previous version of CTP, then upgrading CTP and trying to create your PostgreSQL database with that backup could create errors.
