Standard execution environment limits
The amount of r-code that you can run at one time and how much memory it uses are determined by the following factors:
*R-code directory size — The default is 100 entries, the minimum is five entries, and the maximum is 2,147,483,647. You can set the initial number of entries using the Directory Size (-D) startup parameter. OpenEdge dynamically increases the directory size up to the maximum, as required. Use the Hardlimit (-hardlimit) startup parameter to force OpenEdge to adhere to the limit specified by the Directory Size (-D) startup parameter.
*Execution buffer ceiling — The default is 3096K. You can set the initial ceiling for this buffer up to 65,534K using the Maximum Memory (-mmax) startup parameter. OpenEdge dynamically increases the execution buffer size up to the maximum, as required. Use the Hardlimit (-hardlimit) startup parameter to force OpenEdge to adhere to the limit specified by the Maximum Memory (-mmax) startup parameter.
*Available memory — Available memory is a factor only if it is smaller than the execution buffer ceiling or OpenEdge needs to allocate memory beyond that ceiling.
