Maximum Size of Data

The M server can transmit very large buffers of data back to the Microsoft Windows client. The Windows client receives the returned data from an RPC into a 32-bit PASCAL string. RPCs can be written on the VistA M Server so that they store their results in an M GLOBAL structure, which can span RAM and disk storage media. This GLOBAL storage could be quite large depending on the assigned system quotas to the VistA M Server process. The return of the RPC can deliver this quantity to the Windows client. The actual limit will depend on the capacity that the Microsoft Windows operating system will allow the client to process. Tests on a 32-megabyte RAM system have allowed buffers of several megabytes of data to be transmitted from the VistA M Server to the Microsoft Windows client.
