Important

  • For on-premises customers using MySQL 8.0 or later (which has binary logging enabled by default), the system variable log_bin_trust_function_creators must be set to ON so that Contrast can create stored procedures. For more details, see MySQL documentation.

  • For on-premises customers using MySQL 8.0 or later, the system variable local_infile must be set to ON so that Contrast can accept CSV files to help the import of SCA data. For more details, see icon-external-link.svgSecurity Considerations for LOAD DATA LOCAL.

MySQL and Java requirements for distributed installations

Use these requirements if you are deploying Contrast as a distributed application or are using your own MySQL database. For all other on-premises installations, use the MySQL and Java software included in the Contrast installer.

SuperAdmin account

To ensure that connections for integrations work correctly, create a SuperAdmin account that is different from the default account that Contrast Security created. Continuing to use the default SuperAdmin account can result in connection errors.

Distributed configuration for a large number of agents

If you plan to use more than 100 connected agents, use a distributed configuration. Without a distributed configuration for this situation, you are likely to experience performance issues.
