Release 10.1A: OpenEdge Deployment:
Managing 4GL Applications

R-code execution

OpenEdge executes r-code procedures in different ways, depending on whether you store the r-code files in an r-code library and the type of library.

When executing an r-code procedure from an operating system file in a directory, or from a standard r-code library, OpenEdge accesses and executes the r-code file segments in an execution buffer in local memory. For more information about the standard r-code execution environment, see the "Standard r-code execution environment" section.

When executing an r-code procedure from a memory-mapped r-code library, OpenEdge accesses and executes the r-code file segments in shared memory. For more information about the memory-mapped r-code execution environment, see the "Memory-mapped r-code execution environment" section.

For information about monitoring execution environment activity during a Progress 4GL client session, see the "R-code execution environment statistics" section.

For information about monitoring and optimizing r-code performance, see Chapter 5, " Managing Client Performance."
