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
Mail
com.rapidanalytics.mail.jndi_name Sets the JNDI name of the email session. See changing outgoing email. JNDI identifier None
Triggers
com.rapidanalytics.triggers.delay Sets the delay between active triggers that check conditions (for example, file modifications). Integer 10000 ms
Web
com.rapidanalytics.web.hostname Sets the RapidMiner Server hostname to display to users (to use, for example, for web service URLs). Auto-detected based on configuration. Any None
com.rapidanalytics.web.myport Sets the RapidMiner Server port to display to users (to use, for example, for web service URLs and other generated direct links). Auto-detected based on configuration. Any valid port number 80
com.rapidanalytics.web.session.timeout Sets the timeout for web sessions. Integer 1800s
com.rapidanalytics.web.session.limit.enabled Set to true if the web interface should disallow multiple sessions per user. The server needs to be restarted once this feature is switched on. It's not supported in high availability mode. Boolean false
com.rapidanalytics.web.session.limit.amount Sets the maximum amount of allowed sessions per user in the web interface. Integer 1
com.rapidanalytics.web.rooturl Sets the RapidMiner Server root URL to display to users. Auto-detected based on configuration. Valid URL None
com.rapidanalytics.web.reverse_dns_lookup Specifies whether RapidMiner Server does a reverse DNS (IP address to hostname) when writing to the access log. True to write the reverse DNS lookup results or false to write the IP address to the log False
Scripting extensions
rapidminer.r_scripting.path Specifies the path to the RScript executable in your R installation. Anywhere that is accessible to your machine, but be sure that you have write permission to the location None
rapidminer.python_scripting.path Specifies the path to the Python executable in your Python installation. Anywhere that is accessible to your machine, but be sure that you have write permission to the location None
License
com.rapidanalytics.license.reload_interval Sets an interval in which a trigger periodically reloads the licenses in milliseconds. Long 1800000ms (30 minutes)
Miscellaneous

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
com.rapidanalytics.security.access_control_allow_origin Used to specify the content of the Access-Control-Allow-Origin header for CORS requests. *, or https://example.com/ Header not set (CORS disabled)
com.rapidanalytics.security.access_control_allow_credentials Used to specify the content of the Access-Control-Allow-Credentials header for CORS requests. true or false true
com.rapidanalytics.security.access_control_allow_headers Used to specify the content of the Access-Control-Allow-Headers header for CORS requests. Any comma-separated combination of headers: origin, content-type, accept, authorization origin, content-type, accept, authorization

com.rapidanalytics.security.upload.whitelist A whitelist for file extensions that may be uploaded via the Web UI and from Studio. 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.
com.rapidanalytics.security.upload.max_size Defines the maximum allowed file size in bytes of uploads via the Web UI and from Studio. Integer
com.rapidanalytics.encryption.key Used to specify the key used for property encryption. Currently only relevant for the LDAP Property Encryption Any
