You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: session_ctx.go
    path of file: ./repos/scan4all/vendor/github.com/sijms/go-ora/v2/network
    
    the code of the file until where you have to start completion: package network

import "github.com/sijms/go-ora/v2/network/security"

type SessionContext struct {
	//conn net.Conn
	ConnOption *ConnectionOption
	//PortNo int
	//InstanceName string
	//HostName string
	//IPAddress string
	//Protocol string
	//ServiceName
    
func NewSessionContext(connOption *ConnectionOption) *SessionContext {
	return &SessionContext{
		SessionDataUnit:   connOption.SessionDataUnitSize,
		TransportDataUnit: connOption.TransportDataUnitSize,
		Version:           317,
		LoVersion:         300,
		Options:           1 | 1024 | 2048, /*1024 for urgent data transport*/
		OurOne:            1,
		ConnOption:        connOption,
