The OnePacs Study Retriever will download DICOM instances into memory up to a configurable limit before the instances are stored to a DICOM destination. By default, that limit is 50 individual instances or any single instance greater than 1 MB of size. Thus, the maximum number of instances that the study retriever will store in a single DICOM association is 50, and may be less depending on the size of the instances. On systems with a high-overhead for DICOM network communication, it may be desirable to increase the batch size to a larger value (e.g. 200 instances instead of 50).
The following steps describe the process of modifying the storage batch size in the OnePacs Study Retriever in Windows:
- Stop the OnePacs Study Retriever by right-clicking on the taskbar icon and selecting "Exit"
- Open the file called poller.properties in C:\onepacs\poller\conf in a text editor.
On a new line, add the following property.
storeBatchSize=200
The example above may be modified to use any batch size; 200 is an example.
- Restart the OnePacs Study Retriever by double-clicking on the "Restart OnePacs Study Retriever" desktop icon.
For mac OS Study Retriever, the process is similar, however the poller.properties file is located in the user's home directory under <USERNAME>/onepacs/poller.conf .
Please note that this may increase the overall memory usage of the Study Retriever. You may wish to increase the maximum memory settings to accommodate a larger batch size.
