- Include Sample Services: When it is checked, the User can see system bundled services on the Manage service screen. System bundled services are stored in "Project: Sample" and "Sub project : Sample" Users can't edit or delete these services.
- Enable IPv6: To enable IPV6 support in NetOcean.
- Maximum Request Size: Maximum size of the request. Provide the value in 'bytes' with a range from 0 to 10GB
- Enable Other Protocols: To enable other protocols in NetOcean. By default only HTTP protocol is enabled.
- Maximum Number of IO Vectors:Maximum number of segments to be made for response. Rest response data is truncated. The size should not be less than 256 and should not be more than 256000.

## IO Vector settings

- Increment By: It is set to a certain value, when the I/O vector needs to grow, it will increase its size by that value.
- Maximum Size: The "maximum size" is the upper limit or the maximum capacity that an I/O vector can reach.

## Forward Settings

Disable Forward for all Services To enable/disable the forward requests. Requests are forwarded to the next server (whose server details has to be provided in the forward text field) to serve the response.

- Connection Timeout: Provide the connection timeout value, if forward setting enabled. Its unit is in seconds and default value is 45 sec.
- Response Timeout: Provide the response timeout value, if forward setting enabled. Its unit is in seconds and default value is 60 sec

## NetOcean Performance Settings

- Start Up Mode:To start the HPD in startup mode. Multiple HPD processes are started to handle the load.
  - Normal Mode:To listen on specified IP addresses.
  - Server IP Based Mode:
- Optimize Ethernet Packet Flow: Optimizing Ethernet packet flow typically involves improving the efficiency and performance of data transmission over Ethernet networks.
  - 0: stands for Disable
  - 1: stands for TCP_QUICKACK which helps in quicker acknowledgment of received data
  - 2 stands for TCP_NODELAY , this option is typically used to reduce the latency in data transmission.
- Time Stamp: Timeout in milliseconds (for connections) for the first request.
  - Use Kernel Jiffy:
  - Use CPU frequency:
  - Use Unix System Call (get time of day): a way of representing a timestamp by representing the time as the number of seconds since January 1st, 1970 at 00:00:00 UTC.
- Maximum Connections Per Child: Number of connections established per child. Maximum number of concurrent connections to be handled by one HPD process. Default value is 32768 connections.
- Number of NetOcean Virtual Machine: The number of processes that HPD runs. Number of processes is 2 per CPU. For example: if the machine is dual core CPUs, then total 8 (2*4). processes run. There are the following options.
  - Auto (2 per core)
  - Specified

## PINPAD Settings

- PINPAD Settings: PinPad services are used to serve the requests of PinPad devices. A PIN pad or PIN entry device is an electronic device used in a debit, credit, or smart card-based transaction to accept and encrypt the cardholder's personal identification number (PIN), for example - an ATM machine. Below are the required information required
  - Enable Pinpad Trace
  - Pinpad Ports
  - Keys
