The OnePacs Study Retriever has configurable memory settings for the maximum amount of memory that the embedded java executable may consume. In situations where multiple concurrent downloads of large instances are required, it may be necessary to increase the maximum memory setting for the Study Retriever. Conversely, on systems with very limited memory, it may be desirable to limit the maximum amount of system memory used by the Study Retriever. The default memory settings varies based on the version installed.
Max Memory Settings (-Xmx)
| SR Version | Default | Minimum | Maximum |
|---|---|---|---|
| 8.1 and later | 2048 MB | 256 MB | 4096 MB |
Modifying the minimum memory setting (Xms) is not recommended or supported. Please leave this value at its default.
