Configuring the RDC
You can fine-tune the performance of the RDC in your environment by adjusting its configuration settings, for example, for batching, data validation, and retries.
RDC configuration file
You can use the information in this section to update the configuration settings used by the RDC. The Import API also uses these same settings located in the app.config file.
Use the following instructions to locate the config file on your machine, and set custom configuration properties for the RDC:
- Exit the RDC if it is currently open.
- Navigate to the Relativity.Desktop.Client.exe.config file on the machine where the RDC is installed. By default, this configuration file is located in the following directory:
[Installation_Directory]\kCura Corporation\Relativity Desktop Client
Make a backup copy of this file in case you need to rollback any configuration changes made to it.
- Open the Relativity.Desktop.Client.exe.config file in a text or XML editor and modify it as necessary.
Configuration settings
The Relativity.DataExchange section of the Relativity.Desktop.Client.exe.config contains the configuration properties in the following table.
General settings
| Name | Description | Default Value |
|---|---|---|
| CreateErrorForInvalidDate | When this value is set to True, a zeroed date, such as 0/0/0000, causes an Invalid Date error. When False, the date is treated as a NULL value. | True |
| FileTypeIdentifyTimeoutSeconds | Defines the maximum number of seconds to identify a file type before reaching the timeout. | 10 |
| HttpExtractedTextTimeoutSeconds | Defines the timeout, in seconds, for HTTP/REST-based API web services specifically used for extracted text. This value doesn't impact WebAPI-based web services, which means that WebAPIOperationTimeout setting is still honored. | 900 |
| HttpTimeoutSeconds | Defines the timeout, in seconds, for HTTP/REST-based API web services. This value doesn't impact WebAPI-based web services, which means the WebAPIOperationTimeout setting is still honored. | 300 |
| IOErrorNumberOfRetries | Defines the number of times the RDC retries an operation within an import or export process after an IO failure occurs. | 20 |
| IOErrorWaitTimeInSeconds | Defines the number of seconds the RDC waits before retrying an operation within an import or export process after an IO failure occurs. | 30 |
| LogAllEvents | Enables an option to Save Progress Log when job completes. | False |
| LogConfigFile | Defines the Relativity Logging configuration file name. | LogConfig.xml |
| SuppressCertificateCheckOnClient | When this value is set to True, SSL certificate validation errors are suppressed. When False, SSL certificate validation errors cause job failures. | False |
| TempDirectory | Defines a temp directory override where short lived import files are stored. When not defined, the user profile %TEMP% directory is used. | |
| WebAPIOperationTimeout | Defines the time in milliseconds, which an XML Web service client waits for the reply to a synchronous XML Web service request to arrive. | 600000 |
Transfer settings
| Name | Description | Default Value |
|---|---|---|
| BadPathErrorsRetry | When this value is set to True, bad path errors are
retried during a transfer. When False, permission errors aren't retried and
cause job failures. This setting is a transfer specific setting that addresses scenarios where transfer clients (Aspera in particular) fail to transfer a file because of intermittent I/O errors. | True |
| PermissionErrorsRetry | When this value is set to True, permission errors are retried before and during a transfer. When False, permission errors aren't retried and cause job failures. | True |
| TapiAsperaBcpRootFolder | Defines the root folder where the BCP files are uploaded when using the Aspera transfer client. | |
| TapiFileNotFoundErrorsDisabled | When this value is set to True, missing files aren't treated as errors. When False, missing files are treated as errors. | False |
| TapiFileNotFoundErrorsRetry | When this value is set to True, missing files are retried. When False, missing files aren't retried. | True |
| TapiForceAsperaClient | When this value is set to True, the Aspera transfer client is forced. When False, the best fit transfer client is chosen at runtime. | False |
| TapiForceBcpHttpClient | When this value is set to True,
the HTTP transfer client is forced only for BCP operations. When false, the
best fit transfer client is chosen at runtime. | False |
| TapiForceClientCandidates | Forces an ordered list of transfer clients when probing a workspace and choosing the best client. This value represents a semi-colon delimited list. Native transfer client identifiers must be used, such as FileShare, Aspera, or Http. | |
| TapiForceFileShareClient | When this value is set to True, the file share transfer client is forced. When False, the best fit transfer client is chosen at runtime. | False |
| TapiForceHttpClient | When this value is set to True, the HTTP transfer client
is forced. When false, the best fit transfer client is chosen at runtime. This setting is the same as web mode. | False |
| TapiLargeFileProgressEnabled | When this value is set to True, large-file progress is used by transfer clients to display "Trip x of y" chunk info within the status area. When False, no chunk info is displayed . | False |
| TapiMaxInactivitySeconds | The maximum number of seconds that elapse with no data movement occurring before the transfer is treated as inactive. When this occurs, the import or export job continues but performance may be degraded. | 180 |
| TapiMaxJobParallelism | Defines the maximum degree of parallelism for a transfer client job. This value isn't guaranteed to be honored by all clients. | 10 |
| TapiMinDataRateMbps | Defines the minimum data rate in Mbps units. If set to zero, the best value is chosen. This value isn't guaranteed to be honored by all clients. | 0 |
| TapiPreserveFileTimestamps | When this value is set to True, the RDC preserves the import and export file timestamps. Only direct modes support this functionality. By default, this value is set to False, because preserving file timestamps may degrade performance between 10-20%. | False |
| TapiTargetDataRateMbps | Defines the target data rate in Mbps units. This value isn't guaranteed to be honored by all clients. | 100 |
| TapiTransferLogDirectory | Defines the directory where Relativity Logging and transfer client logs are stored. | %temp%\RDC_log\ |
Import settings
| Name | Description | Default Value |
|---|---|---|
| AuditLevel | Controls the details collected in an audit:
| FullAudit |
| CreateErrorForInvalidDate | When this value is set to True, a zeroed date, such as 0/0/0000, causes an Invalid Date error. When False, the date is treated as a NULL value. | True |
| DisableImageLocationValidation | Disables the validation of the image file locations for all jobs when set to True. See Additional guidelines for disabling file validation. | False |
| DisableImageTypeValidation | Disables the validation of image file types for all jobs when set to True. Image type validation is dependent upon image location validation. See Additional guidelines for disabling file validation. | False |
| DisableNativeLocationValidation | Disables the validation of the native file locations for all jobs when set to True. See Additional guidelines for disabling file validation. Don't use the DisableNativeLocationValidation flag when copying files to a repository. File locations are validated regardless of the flag before they are copied. | False |
| DisableNativeValidation | Disable the validation of native file types for all jobs. Native type validation is dependent upon native location validation. See Additional guidelines for disabling file validation. | False |
| DynamicBatchResizingOn | When this value is set to True, the batch size is automatically decreased by 100 when a large import job is in progress, and it causes a timeout. | True |
| ImportBatchMaxVolume | Defines the maximum number of bytes before the metadata is imported. | 10485760 |
| ImportBatchSize | Defines the maximum number of documents or objects before the metadata is imported. | 1000 |
| JobCompleteBatchSize | Defines the file count threshold at which the RDC completes and recreates the transfer job used to transfer files. | 50000 |
| MinimumBatchSize | When AutoBatch is set to True, this value represents the lower bound on the batch size. Batch sizes can't be smaller than this value. | 100 |
Additional guidelines for disabling file validation
You can disable file validation by setting these configuration settings to true:
- DisableImageLocationValidation
- DisableImageTypeValidation
- DisableNativeLocationValidation
- DisableNativeValidation
Review the following guidelines before disabling file validation:
- When you disable file type validation, you do not receive any warnings regarding unsupported file types. It's therefore possible for files to be imaged and result in errors.
- Disabling the file type validation also causes the application to set the Relativity Native Types field to Unknown Format.
- Setting a native type to unknown has no effect on productions or OCR.
- Setting a native type to unknown has no effect on how the viewer or imaging engine handles the file. This means that a native type of unknown can't be the sole cause of an error in the viewer or the imaging engine. If a file is designated unknown and it actually has an unsupported file type, the Viewer or imaging engine throws an error based on the fact that it has an unsupported file type.
Export settings
| Name | Description | Default Value |
|---|---|---|
| ExportBatchSize | Defines the maximum number of export documents per batch. | 1000 |
| ExportErrorNumberOfRetries | Defines the number of times the RDC retries an operation within an export process after a non-IO failure. This value should be greater than or equal to the IOErrorNumberOfRetries value. | 20 |
| ExportErrorWaitTimeInSeconds | Defines the number of seconds the RDC waits before retrying an operation within an export process after a non-IO failure. This value should be greater than or equal to the IOErrorWaitTimeInSeconds value. | 30 |
| ExportThreadCount | Defines the number of threads that get created during
export. This configuration setting is only used when the UseOldExport setting is true. | 2 |
| UseOldExport | When this value is set to True, the legacy export method is used. When False, the new export method is used. The old export should only be used when encountering compatibility issues. | False |
