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

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
