Resolution:
The recommended memory size depends on a number of factors including number of concurrent users viewing the screens, amount of data contained in the screens, etc. but typically we recommend that customers allocate at least 256-512 MB to the server process.

This can be done by setting the following environment variable:

RTV_JAVAOPTS=-Xmx256m

This env variable can be used to pass other JVM specific options to RTView. All RTView components (builder, server, historian) will be affected by RTV_JAVAOPTS.

It should also be remembered that  RTV_JAVAOPTS is not included in the Start menu launchers. The Start menu launchers do not include the %RTV_JAVAOPTS% variable that allows the input of Java options.  In order to use Java options you must run programs from the command line.

In order to apply the RTV_JAVAOPTS, you will need to start the RTView components from the command line, for instance:

run_dataserver
or
run_viewer
