181 Use case: receiving 10 1GB instances in parallel can consume up to 20 GB
Alain Mazy <am@osimis.io>
parents: 4978

182 Alternative option 1: write an "external application/plugin" that would take care of these receptions, write the
Alain Mazy <am@osimis.io>
parents: 4978
diff changeset
183 file at the right place and send a signal to Orthanc to "adopt" the file.
Alain Mazy <am@osimis.io>
parents: 4978
diff changeset
184 Alternative option 2: declare a memory resource (X GB) that is available for reception. Every time
Alain Mazy <am@osimis.io>
parents: 4978
diff changeset
185 Orthanc starts receiving a file, it reserves the memory or twice the memory (through a Semaphore)
Alain Mazy <am@osimis.io>
parents: 4978
diff changeset
186 if no memory is available, it waits and possibly timeouts returning a 503 or DIMSE A700 (out of resources).
