HTTP I/O buffer
When HTTP I/O requests exceed the memory limit, caching switches to a temporary file. The following lines from boot.properties
display the default values related to buffer size:
# initial size of the in-memory I/O buffer for HTTP requests
#openidm.temporarystorage.initialLength.bytes=8192
# maximum size of the in-memory I/O buffer for HTTP requests
#openidm.temporarystorage.memoryLimit.bytes=65536
# maximum size of the filesystem I/O buffer for HTTP requests, for when memoryLimit is exceeded
#openidm.temporarystorage.fileLimit.bytes=1073741824
# absolute directory path of filesystem I/O buffer for HTTP requests, and uses system property java.io.tmpdir by default
#openidm.temporarystorage.directory=/var/tmpopenidm.temporarystorage.initialLength.bytes-
Initial size of the memory buffer in bytes.
Default: 8192 bytes (8 KB). Maximum: The value of
openidm.temporarystorage.memoryLimit.bytes. openidm.temporarystorage.memoryLimit.bytes-
Maximum size of the in-memory I/O buffer for HTTP requests. When the memory buffer is full, the content is transferred to a temporary file.
Default: 65536 bytes (64 KB). Maximum: 2147483647 bytes (2 GB).
openidm.temporarystorage.fileLimit.bytes-
Maximum size of the temporary storage file. If the downloaded file is larger than this value, IDM throws the exception
HTTP 413 Payload Too Large.Default: 1073741824 bytes (1 GB). Maximum: 2147483647 bytes (2 GB).
openidm.temporarystorage.directory-
The absolute directory path of the filesystem I/O buffer for HTTP requests.
Default: The value of the system property
java.io.tmpdir.
