Table of system settings for RapidMiner Server
Notice that you can link directly to any of the properties in the table using the whole property name as an ID, for example #com.rapidanalytics.web.anonymous_resources
| Property | Description | Accepted values | Default |
|---|---|---|---|
| Database | |||
| com.rapidanalytics.db.max_rowlength | Sets the maximum number of bytes per row when storing an ExampleSet. If an ExampleSet contains more Attribute data than can be stored in max_rowlength, RapidMiner Server splits it into multiple tables. Reduce this number if you receive a database error that RapidMiner Server created tables with too many columns. | Integer | 20000 |
| com.rapidanalytics.db.stream_chunk_size | Sets the buffer size when reading data from the database. | Integer | 500 rows |
| com.rapidanalytics.db.table_prefix | Sets the prefix for tables storing example sets in the RapidMiner Server database. | Any string allowed as an identifier in your database | es_ |
| com.rapidanalytics.db.exampleset.jndi | Sets the JNDI name of the data source connections where RapidMiner Server stores example sets; defined in standalone.xml. | JNDI identifier | java:/jdbc/RapidAnalyticsDS |
| com.rapidanalytics.db.sql_dialect | Sets the SQL dialect used by the operations database. | MYSQL, ORACLE, MICROSOFT, POSTGRES. But no need to ever edit. | Set on installation by the DB System argument, in the Database Configuration window (so no need to edit). |
| Anonymous access—Requires an "anonymous" user account | |||
| com.rapidanalytics.web.anonymous_resources | Sets whether resources can be accessed without authentication under /api/rest/public/resources. Use this when implementing the anonymous user functionality. | True to allow access or false to deny access | False |
| com.rapidanalytics.web.anonymous_services | Sets whether web service processes can be accessed without authentication under /api/rest/public/processes. Use this when implementing the anonymous user functionality. | True to allow access or false to deny access | False |
| com.rapidanalytics.web.anonymous_reports | Sets whether web apps can be accessed without authentication. Web apps do not have a fixed URL; the access URL is shown while editing the app. Use this when implementing the anonymous user functionality. | True to allow access or false to deny access | False |
| Process log | |||
| com.rapidanalytics.process.log.enable | Sets whether to log process output. Logs are visible in the web interface under Processes > Scheduler and linked from RapidMiner Studio. | True to log process output or false to discard. | True |
| com.rapidanalytics.process.log.update_delay | Sets the interval, in milliseconds, between updates to the database with the latest log records. That is, instead of writing immediately to the log, messages can be delayed for this interval and written at one time. | Integer | 1000 milliseconds |
| com.rapidanalytics.process.log.continuous | Specifies whether to write to the logs as a process executes or whether to write all log data at process completion. | True to write continuously or false to write at completion | True |
| com.rapidanalytics.process.log.limit_access_to_owner | Sets accessibility of the process log. If true, log is only available to the user that started the process. If false, log is available to any user with Read access to the folder. | True or false | False |
| Process execution | |||
| com.rapidanalytics.webservices.concurrency | Sets the concurrency level (i.e. how many CPU cores are used) for each web service that runs. Defaults to 1 which means each web service runs in a single thread and thus responds faster. If you offer web services that take longer to run(several minutes to hours), you can increase this setting to make use of multiple CPU cores (limited by your license) for each web service process. This has the same effect as the Number of threads setting in RapidMiner Studio. Note that if you have many web service calls (hundreds at the same time) for processes that can use multiple cores (e.g. via Loop operators), this can cause new web service calls to fail! This is due to a global limit in the number of threads depending on various system parameters. | Integer | 1 |
| Directories | |||
| com.rapidanalytics.plugindir | Defines the directory where RapidMiner Server stores user-added extensions that are loaded at start up. | You can create the plugin directory anywhere that is accessible to your machine, but be sure that you have write permission to the location. Bundled extensions (no installation necessary) are stored in a separate directory that is independent of the path specified here. | Specified at installation |
| com.rapidanalytics.uploaddir | Defines the directory where RapidMiner Server stores temporary binary files uploaded by the user and needed for processes. | You can create the uploads directory anywhere that is accessible to your machine, but be sure that you have write permission to the location. If the RapidMiner Server host has a small hard disk, make sure you create the directory in a place that can handle the potentially large temporary files. | Specified at installation |
| Logging | |||
| com.rapidanalytics.accesslog.db.mode | Determines when access to resources are logged to the database. | ALWAYS, NEVER, or ONLY_ERROR. | ALWAYS |
| com.rapidanalytics.accesslog.file.mode | Determines when access to resources are logged to a file. | ALWAYS, NEVER, or ONLY_ERROR. | NEVER |
| com.rapidanalytics.accesslog.file.destination | Specifies the destination to write the access log file to. Only applicable if com.rapidanalytics.accesslog.file.mode is ALWAYS or ONLY_ERROR. | Filename | None |

| LDAP username and group filters | |||
| com.rapidanalytics.access.userfilter | Sets the filter to restrict access of LDAP authenticated users based on their username. If the username matches the filter then access is granted. Blank or undefined value does not restrict access. | Regular expression | |
| com.rapidanalytics.access.groupfilter | Sets the filter to restrict access of LDAP authenticated users based on their LDAP group membership. If any of the LDAP groups name that the user belongs to matches the filter then access is granted. Blank or undefined value does not restrict access. | Regular expression | |
| Security | |||
| com.rapidanalytics.security.x_frame_options | Set the X-FRAME-OPTIONS header for web site responses to prevent embedding of pages into other websites (e.g. as an iframe). This prevents clickjacking attacks. Please note that setting this header to DENY might also affect the RapidMiner Server UI. | DENY, SAMEORIGIN, or ALLOW-FROM https://example.com/ | Header not set |

If a whitelist is defined, the blacklist will be ignored. | Any comma-separated combination of file extensions, including "none" as a filter for files without any extensions. In case of an empty whitelist all uploads will be blocked. For example, the whitelist 'pdf,csv,none' permits the upload of files with pdf and csv extensions and the upload of files with no file extension. | |
| com.rapidanalytics.security.upload.blacklist | A blacklist for file extensions that should NOT be uploaded via the Web UI and from Studio. If a whitelist is defined, this blacklist will be ignored. | Any comma-separated combination of file extensions, including "none" as a filter for files without any extensions. For example, the blacklist 'exe,sh,none' blocks files with the file extensions exe and sh and also blocks files with no file extension. | |
| com.rapidanalytics.security.upload.content_type.allowed_types | Defines allowed content-types of uploads via the Web UI and from Studio. The content-type check will happen after a file has been uploaded. It uses magic bytes to extract the real content-type of a file regardless of the file extension. | Any comma-separated combination of allowd content-types. In case of an empty list all uploads will be blocked. For example, the content-types 'application/pdf,application/zip' permit the upload of PDF and Zip files. | |
