## Overview

Data processor captures raw files as input, processes the data and saves it in a shared memory. It also creates correlation services corresponding to that data in High Performance Daemon (SERVICE VIRTUALIZATION SERVER) correlation directory. Data manager arranges the data saved in shared memory according to session ids. Responses are mapped corresponding to different session ids.

## Directory

- Log Directory: Directory from where data processor captures the log data for processing.
- Response Directory: After processing, the response is provided at the response directory.
- Backup dump shared memory in file:To create a backup in shared memory, select ‘Yes’ from the drop-down list.
- Total Threads: Select the Total Threads from the drop-down list. It denotes the number of threads to be created during the processing of the access log file. It can range from 1 to 32. Default value is 1.

## Services

Here, user needs to provide a service name for a particular URL.

- Service: Specify the service name:
- URL: Enter the URL of the service.

## Headers

Here, user can add headers in the response.

- Header: Enter the header details in Name: Value
- URL: Specify the URL.

Here, in this section, user can configure some advance settings for data processor. There are following labels under this:

- Maximum Day(s): Denotes the maximum number of days for which the log files can be processed.
- Request/Response Table Size: Denotes the chunk size for intermediate request/response tables. User needs to provide the following details.
  - Initial: It is the initial file size. By default, it is 1024 KB.
  - Incremental: It is the incremental to the initial file size in KB. By default, it is incremented by 1024 KB.
- Big Buffer Size: It denotes the chunk size of big buffer used. User needs to provide the following details.
  - Initial: It is the initial buffer file size. By default, it is 1048576 KB.
  - Incremental: It is the incremental to the initial file size. By default, it is 1048576 KB.
- Delimeter: The separator between two fields of the raw files. Default is pipe delimeter (|).
- Shared Memory Path: It denotes the shared memory data path.
- Shared Memory Key Path: It denotes the shared memory key path. The Default path is /var/www/Service Virtualization Server/reactive_replay.
