TAR Retriever Service.
Dependencies
Attributes
#CacheRoot
Root directory in which retrieved tars are extracted. A relative path name is resolved relative to archive-install-directory/server/default/.
For reliable function of the deletion of least recent accessed objects, a separate file system should be used for the cache. You also have to take care for moving existing files in the cache to the new location yourself!
Default Value: tar-extracted
#CacheJournalRootDirectory
Root directory for cache journal files. A relative path name is resolved relative to archive-install-directory/server/default/.
You have to take care for moving existing journal files to the new location yourself!
Default Value: tar-extracted-journal
#CacheJournalFilePathFormat
Defines journal file path, with 'yyyy' will be replaced by the current year, 'MM' by the current month, 'dd' by the current date, 'HH' by the current hour and 'mm' by the current minute.
Can only be modified if the cache is empty!
Default Value: yyyy/MM/dd/HH/mm
#MemoryCacheCapacity
Defines maximal number of journal file entries cached in memory to reduce number of duplicate entries in journal files. Should be set about the expected number of concurrent retrieves of objects located on TAR file systems.
Default Value: 5
#MinimumFreeDiskSpace
Minimum free disk space on Cache Directory. If the free available disk space on the cache directory falls below this value, least recent accessed sub-directories are deleted, BEFORE further TARs are retrieved and extracted. 1MB = 1000000 bytes, 1GB = 1000MB.
Default Value: 50MB
#PreferredFreeDiskSpace
Preferred free disk space on Cache Directory. If the free available disk space on the cache directory falls below this value, least recent accessed sub-directories are deleted, WITHOUT blocking retrieve and extraction of further TARs. 1MB = 1000000 bytes, 1GB = 1000MB.
Default Value: 100MB
#CheckMD5
Defines if the MD5 sum of TAR file entries shall be checked against values in first entry MD5SUM file during retrieval. If the check fails, the retrieval will fail. If activated, but the first TAR entry is not the MD5SUM file, a WARN messages will be logged in server.log.
Default Value: true
#TarFetchCommand
External command to fetch tarballs from the source file system, with
- %d will be replaced by the source file system name,
- %f will be replaced by the path of tarball on the source file system,
- %p will be replaced by the destination path.
NONE = TAR file on local accessable file system.
Default Value: NONE
#TarIncomingDirectory
Directory in which TARs shall be retrieved by external #TarFetchCommand. A relative path name is resolved relative to dcm4chee_home/server/default/.
Not effective if #TarFetchCommand='NONE'.
Default Value: tar-incoming
#BufferSize
Size of write byte buffer.
Default Value: 8192
#LRUCacheSize
Number of cached references to least recent accessed directories.
Default Value: 20
#Name

#State
The status of the MBean
#StateString
