Introduction
Parasoft DTP requires a relational database. DTP can be connected to an external MySQL, PostgreSQL, or Oracle database server. This section describes installing and configuring MySQL servers. Contact your Oracle or PostgreSQL administrator for details on installing and configuring those database servers.
Database Requirements
DTP supports MySQL 5.7.x to 8.0.x.
If data continuously loads in an explorer view, increase the value of the read_rnd_buffer_size variable.
If binary logging is enabled in MySQL, you must use the "ROW" or "MIXED" binary log format. The "STATEMENT" format will not work.
DTP does not ship with the MySQL, PostgreSQL, and Oracle JDBC drivers necessary to set up a database connection. Download the drivers and place them in the <DTP_DATA_DIR>/lib/thirdparty directory after completing the installation.
Installing MySQL Database Server
Refer to the MySQL documentation for instructions on how to install and configure MySQL:
- Windows: http://dev.mysql.com/doc/refman/8.0/en/index.html.
- Linux: https://dev.mysql.com/doc/refman/8.0/en/linux-installation-native.html
Many Linux distributions come with MySQL pre-installed. Contact your Linux administrator for details on your Linux system. If you need to install MySQL, consult the MySQL documentation for installation instructions specific to your Linux distribution.
Additional Notes
- MySQL should be installed as a service to be launched automatically upon system startup.
- Do not set for an international character set.
- Check the available disk space in the location where Report Center data will be located. On Windows, the location is usually: C:\Program Files\MySQL\MySQL Server [version]\data\
Assign and remember a password for the root user. You can set the password from the command line:
mysqladmin -u root password 'new-password'
Check your MySQL database for corruption on a regular basis to ensure data integrity using the following command (Windows):
mysqlcheck -u dtp -pgrs DTP
DTP Enterprise Pack Database
DTP Enterprise Pack, which includes Extension Designer, ships with its own embedded MongoDB. If you are installing DTP Enterprise Pack, and intend to use the embedded MongoDB, we recommend using an XFS file system in Linux or an NTFS file system in Windows, as per the MongoDB documentation and described in the excerpt below. If you are planning to use an external MongoDB instead, refer to the requirements for whatever version you intend to use.
- Linux/Unix: format your drives into XFS or EXT4. If possible, use XFS as it generally performs better with MongoDB.
- With the WiredTiger storage engine, use of XFS is strongly recommended to avoid performance issues found when using EXT4 with WiredTiger.
- If using RAID, you may need to configure XFS with your RAID geometry.
- Windows: use the NTFS file system. Do not use any FAT file system (i.e. FAT 16/32/exFAT).
Minimum Number of Database Connections
The database server should provide at least 150 concurrent connections for DTP. If the database server does not provide sufficient connections, DTP may not be able to create a new connection to the database prior to reaching the maximum number of connections.
JDBC Drivers
The standard DTP distribution installation does not ship with the MySQL, PostgreSQL, and Oracle JDBC drivers necessary to set up a database connection. You will need to download the driver for your database software separately.
| MySQL | For MySQL databases (5.7.x - 8.0.x), it is recommended that you use the latest version (8.0.x) of MySQL Java Connector. |
|---|---|
| PostgreSQL | For PostgreSQL database, it is recommended that you use the latest version (42.x) of JDBC driver. |
| Oracle | For Oracle databases, you will need to download the JDBC driver version recommended for your version of Oracle that will work with DTP:
Refer to the Oracle documentation for information on choosing the correct driver: https://www.oracle.com/database/technologies/faq-jdbc.html |
When the installation is complete, place the drivers in the <DTP_DATA_DIR>/lib/thirdparty directory. By default, the <DTP_DATA_DIR> directory for Windows is installed in the C:\ProgramData\Parasoft directory. On Linux, the data directory is set during installation. See Installation Directories for details.
You do not need to download and install the JDBC drivers if you are installing the DTP distribution that includes an embedded database server. The drivers are packaged with the database server so that you can begin using the database immediately.
MySQL Charset and Collation Settings
The MySQL creation script for the DTP database uses the character set utf8 and collation utf8_general_ci so that UTF-8 characters (e.g., Japanese or Chinese) can be stored in the database. DTP does not support UTF-8 4 byte character encoding ("utf8mb4")
The MySQL server character set and collation must also be set to UTF-8 to save UTF-8 characters in the database. We highly recommend that the MySQL server changes are made prior to creating the database:
- Locate the my.ini (Windows) or my.cnf (Linux) and open it in an editor
- In the section under [mysqld], add/edit the following properties:
character-set-server = utf8
collation-server = utf8_general_ci
See the MySQL documentation for more information about server character set configuration: https://dev.mysql.com/doc/refman/5.6/en/charset-server.html.
Oracle Charset and Collation Settings
Oracle recommends setting the target character set to AL32UTF8. See the Oracle Database Migration Assistant for Unicode documentation for instructions: https://docs.oracle.com/database/121/DUMAG/ch2migrasteps.htm#DUMAG136.
Open File Descriptor Limit
DTP may make many simultaneous requests to the server, which may cause the MySQL server to open many files at the same time to process the requests. As a result, the limit on open file descriptors set by MySQL may be exceeded. Please refer to the MySQL documentation for more information on this issue, including possible resolutions: http://dev.mysql.com/doc/refman/5.6/en/table-cache.html.
