Value cache settings
Registry settings for the Value Cache are stored under:
HKEY_LOCAL_MACHINE\Software\SPSS\mrInterview\3\InterviewCache
Settings
CacheSubscriptionTimeout
The maximum time in minutes that a file can remain in the cache.
Default: 2880 minutes (48 hours)
CompletedFolder
The location to move cached files to after they have been successfully transferred.
If no value is specified for CompletedFolder, the cached files are deleted after they have been successfully transferred.
If it is not possible to move a file to the CompletedFolder, an error is logged and the file is left in its current location.
Completed cache files can be kept for each project. This might be useful where a particular project needs the original data files for auditing purposes.
To save completed cache files for a particular project, do the following:
1. Add the KeepCompletedCacheFiles DPM site property at the site level, and then set it to False.
2. For the particular project, add the KeepCompletedCacheFiles property at the <ProjectName>\mrInterview level, and then set it to True.
3. Set CompletedFolder.
To save completed cache files for all projects, do the following:
1. Either set the KeepCompletedCacheFiles property at the site level to True, or delete the property.
2. Set CompletedFolder.
Default: Not set
CompletedFolderGroupByProject
True moves completed cache files to a subfolder under the project folder based on the project name.
FailureFolder
The location to move cached files to if they cannot be transferred.
When no value is specified for the FailureFolder, cache files that fail to transfer are renamed with a .BAK extension to ensure that they are no longer considered as cache files by the cache component.
If the cached file cannot be moved to the FailureFolder, the transfer is continually retried until either the transfer succeeds or the file can be moved to the specified failure folder. In this situation the configured MaxRetryAttempts value might be exceeded.
Default: Not set, but the installation default is:
[INSTALL_FOLDER]\IBM\SPSS\DataCollection\<version>\Interviewer Server\Cache\TransferFailed
LocalDirectory
The pathname of a local folder to use for the Value Cache.
Default:
[INSTALL_FOLDER]\IBM\SPSS\DataCollection\<version>\Interviewer Server\Cache
MaxRetryAttempts
The number of times to retry transferring a file if the initial attempt fails.
Default: 3
RetryDelay
The delay in minutes before attempting to re-transfer a file that previously failed to transfer.
Default: 15 minutes
ScanInterval
The time in minutes between searches for files that require transfer.
Default: 5 minutes
