Description

Spool Directory

Dependencies

Attributes

ArchiveDirPath

Path of Archive Spool Directory, where the DICOM Storage SCP files received DICOM instances. Relative path names will be resolved against directory $DCM4CHEE_HOME/server/default/data/."

Default Value

archive

NumberOfArchiveBuckets

Number of Sub Directories in Archive Spool Directory.

Default Value

337

ArchiveDiskUsage

Estimated current Disk Usage in Archive Spool Directory.
Calculated by accumulation of length of files, but ignoring allocation of disk space by directories. 1MB = 1000000 Byte, 1GB = 1000MB.

ArchiveHighWaterMark

High Water Mark for Archive Disk Usage.
Format: #.#MB or #.#GB with 1MB = 1000000 Byte, 1GB = 1000MB.
Storage of further Objects by DICOM Storage SCP will be rejected, as long ArchiveDiskUsage > ArchiveHighWaterMark.

The actual maximal used disk space is higher than this value, because the current ArchiveDiskUsage must EXCEED the configured HighWaterMark, to cause DICOM Storage SCP to reject further storage requests.

Default Value

10GB

ArchiveHighWater

True if ArchiveDiskUsage > ArchiveHighWaterMark.

ArchiveDiskUsageRefreshInterval

Interval between (re)calculating of ArchiveDiskUsage in days (##d), hours (##h) or minutes (##m). Corrects possible inaccuracy of incremental updates of ArchiveDiskUsage.

Default Value

1h

PurgeArchiveDirAfter

Maximal persistence duration for Instances in Archive Spool Directory in days (##d), hours (##h) or minutes (##m). 0 = Infinite Persistenz.

Default Value

2h

FilesetDirPath

Path of File-set Spool Directory, where the Media Composer Service prepares media content directories and the Make ISO Image Service stores generated ISO image files. Relative path names will be resolved against directory $DCM4CHEE_HOME/server/default/data/."

Default Value

fileset

FilesetDiskUsage

Estimated current Disk Usage in File-set Spool Directory.
Calculated by accumulation of length of files, but ignoring allocation of disk space by directories. 1MB = 1000000 Byte, 1GB = 1000MB.

FilesetHighWaterMark

High Water Mark for File-set Disk Usage.
Format #.#MB or #.#GB with 1MB = 1000000 Byte, 1GB = 1000MB.
Initiation of further Media Creation via N-ACTION RQ will be rejected by the Media Creation Management SCP, as long #FilesetDiskUsage > #FilesetHighWaterMark.

The actual maximal used disk space is notable higher - ~ 2x capacity of media; in case of media splitting even higher - than this value, because the current FilesetDiskUsage must EXCEED the configured HighWaterMark, to cause the Media Creation Management SCP to reject further Media Creation Initiation requests.

Default Value

10GB

FilesetHighWater

True if #FilesetDiskUsage > #FilesetHighWaterMark.

FilesetDiskUsageRefreshInterval

Interval between (re)calculating of #FilesetDiskUsage in days (##d), hours (##h) or minutes (##m). Corrects possible inaccuracy of incremental updates of FilesetDiskUsage.

Default Value

1h

PurgeFilesetDirAfter

Maximal persistence duration of residual File-set directories and ISO image files in File-set Spool Directory in days (##d), hours (##h) or minutes (##m). 0 = Infinite Persistenz.

Default Value

2h

RequestDirPath

Path of Directory where received Media Creation Requests are stored. Relative path names will be resolved against directory $DCM4CHEE_HOME/server/default/data/."

Default Value

request

PurgeMediaCreationRequestsAfter

Persistence duration for Media Creation Requests in days (##d), hours (##h) or minutes (##m). 0 = Infinite Persistenz.

Default Value

1d

LabelDirPath

Path of Directory where created Disk Label Files are stored. Relative path names will be resolved against directory $DCM4CHEE_HOME/server/default/data/."

Default Value

label

PurgeLabelDirAfter

Persistence duration of residual Disk Labels in Label Spool Directory in days (##d), hours (##h) or minutes (##m). 0 = Infinite Persistence.

Default Value

1h

PurgeInterval

Interval in hours (##h), minutes (##m) or seconds (##s) to check the Spool Directory for expired files.

Default Value

1m

Default Value

dcm4chee.cdw:service=Scheduler
