To open the real-time Disk_Deprecated forwarding agent configuration dialog from a workflow configuration, you can do one of the following:
- right-click the agent icon and select Configuration...
- double-click the agent icon
Disk_Deprecated Tab
General Tab
Disk_Deprecated forwarding agent - General tab
| Setting | Description |
|---|---|
| Input Type | The agent can act on two input types:
If you select MultiForwardingUDR, the behavior of the agent will be different. For further information, see Real-Time Disk_Deprecated Forwarding Agent MultiForwardingUDR Input. |
File Information
| Setting | Description |
|---|---|
| Directory | Enter the path of the target directory on the local file system of the EC, where the forwarded files will be stored. The path can be absolute or relative to the |
| Create Directory | Select this check box to create the directory path that you specify in Directory. The directories are created when the workflow is executed. |
| Compression | Select Gzip to decompress files before collection and insertion into the workflow. If the collected files are not compressed, select No Compression. |
File Closing Criteria
When any of the following criteria is fulfilled, the current file will be closed and an output file will be generated.
The time and volume counters that are evaluated against the criteria are reset each time a batch is closed.
Enter 0 (zero) in a field to disable a criterion.
| Setting | Description |
|---|---|
| Volume (bytes) | Enter a file closing criterion based on the processed UDR volume in bytes. The size of the output file will not exceed the value in this field unless it is set to 1 (one byte). |
| Volume (UDRs) | Enter a file closing criterion based on the number of processed UDRs. |
| Timer (sec) | Enter a file closing criterion based on time. |
File Synchronization CriteriaÂ
When any of the following criteria is fulfilled, the agent will synchronize a disk buffer with the batch data that is stored the in-memory. The synchronized data is stored in a subdirectory named DR_TMP_DIR under the target directory.
| Setting | Description |
|---|---|
| Volume (bytes) | Enter a synchronization criterion based on the processed UDR volume in bytes. |
| Volume (UDRs) | Enter a synchronization criterion based on the number of processed UDRs. |
| Interval (sec) | Enter the length of synchronization interval in this field. |

Each batch is handled by a separate worker process with its own processing queue. If the queue size or maximum number of concurrent batches is exceeded, the agent immediately sends the received data to error handling by routing an ErrorUDR to the workflow. This UDR contains the original data and error information.
If a worker fails to write or move data, the agent will retry the last operation for a configurable number of times. As a last resort, it will send the data to error handling. Data that is received while the agent is attempting to recover from an error is immediately sent to error handling.
For more information about error handling, see Closing Batches from APL and Error Handling.
Use the settings below to define the worker queue size and how the agent should behave when error conditions occur.
| Setting | Description |
|---|---|
| Concurrent Batches Limit | Enter the number of open batches that can be handled by the agent. Use the value zero (0) for an unlimited number of batches. It is recommended to use a non-zero when there is a high throughput of small batches, e g containing a single UDR. This will prevent out-of-memory errors. |
| Worker Queue Limit | Enter the maximum number of incoming UDRs that can be queued by worker processes. |
| Error Buffer Limit | The error buffer contains data will be routed to the workflow via Enter the maximum number of bytearray UDRs that can be stored in the buffer, and in the routed UDR. |
| Error Buffer Timeout (sec) | Enter the maximum time in seconds that worker processes should wait for new data, assuming that the error buffer is not empty, before routing an ErrorUDR to the workflow. |
| Retries on Failure | Enter the maximum number of times worker processes should attempt synchronization on failure, e g when writing to the file stream. |
| Retries for Moving Files | Enter the maximum number of times that worker processes should attempt to move the synchronized data in DR_TMP_DIR to the target destination. |
| Recovery Attempt Interval (sec) | Enter the number of seconds between retry attempts. |
| Orphan File Suffix | Enter a suffix that should be appended to the target file names when the agent recovers temporary files after a workflow restart. |
FileName Template Tab
The names of the created files are determined by the settings in the Filename Template tab. For a detailed description of the Filename Template tab, see Workflow Template.
