On Windows platforms, both the R session created by Rserve and Apache Tomcat used by DeployR have default memory limits of 2 GB. To transfer data and perform operations that may require more memory, these defaults can be increased.Rserve R session memory limit:To increase the memory available to the R session, add the following to the beginning of R scripts that may create objects too large for 2 GB of RAM:
memory.limit(size=#####)
where ##### is the amount of memory to make available to the R session (in MB) up to the amount of physical memory available. Apache Tomcat POST limit:Apache Tomcat has a default POST message size limit of 2 GB. If it is necessary to increase this to transfer larger DeployR messages, edit Tomcat's C:\Revolution\DeployR-7.1\Apache_Tomcat\conf\server.xmland add maxPostSize="0" to the Connector stanza as shown below:
<Connector port="7100" protocol="org.apache.coyote.http11.Http11NioProtocol" compression="1024" compressableMimeType="text/html,text/xml,text/json,text/plain, application/xml,application/json,image/svg+xml" connectionTimeout="20000" maxPostSize="0"redirectPort="7101" />
Restart Apache Tomcat/DeployR.
