This study provides some insights into the use of speech acts by Vietnamese EFL learners from a cross-cultural perspective. It is suggested that the influence of culture has resulted in students’ common failures to understand and perform English speech acts. To minimize this kind of pragmatic failure, it is recommended that EFL teachers raise students’ awareness of some cultural issues in cross-cultural communication. Furthermore, it is necessary to incorporate speech acts into English language teaching with authentic input and lifelike communicative activities.

Cài Oracle cần như sau: 1. Tạo 2 Groups: đặc tên là oinstall và dba 2. Tạo 1 User account tên là: oracle (note: Đúng ra đặt là Tí Tèo gì củng được, nhưng conventional, thấy thiên hạ cài Oracle hay đặt là vậy.) Login as root, run: � # groupadd oinstall # groupadd dba # useradd -m -g oinstall -G dba oracle Tạo password cho user: oracle # passwd oracle Changing password for user oracle. New UNIX password: Retype new UNIX password: passwd: all authentication tokens updated successfully.

Users and Security Security domain The database administrator defines the names of the users who are allowed to access a database. A security domain defines the settings that apply to the user. Authentication mechanism A user who requires access to the database can be authenticated by one of the following: Data dictionary Operating system Network The means of authentication is specified at the time the user is defined in the database and can be altered later. This lesson covers authentication by database and by operating system only.

Initialization Parameter Files In order to start an instance and open the database, you must connect as SYSDBA and enter the STARTUP command. The Oracle server will then read the initialization parameter file and prepare the instance according to the initialization parameters contained within. Note: You must have SYSDBA privilege. Authentication and the SYSDBA privilege will be discussed in later lessons.

We now begin our look at building protocols using the basic tools that we have discussed. The discussion in this lecture will focus on issues of key establishment and the associated notion of authentication These protocols are not real, but instead are meant to serve just as a high-level survey Later lectures will go into specific protocols and will uncover practical challenges faced when implementing these protocols
