8. conv = conversion: Convert the file with the specified parameter.
Ascii: Convert ebcdic to ascii
Ebcdic: Convert ascii to ebcdic
Ibm: Convert ascii to alternateebcdic
Block: converts each row to the length of cbs. spaces are used to fill the remaining parts.
Unblock: the length of each row is cbs, and the remaining part is fi

I,FTP: File Transfer Protocol
1. FTP protocol: two TCP connections are used to transmit a file.(1) control connection:The control connection is usually established on the client server. The control connection always waits for the customer to communicate with the server. The connection sends the command from the client to the server and returns the server's response.(2) Data Connection:This connection is used for data transmission.2. Data Representation:(1) file type:◆ ASC

Because the hyphen '-' indicates itself in quoted-printable encodingWhen encoding the body content of a multipart object, we must note thatPurpose: we must not make a boundary identifier appear in the subject part of the encoding!(A better way is to include a "= _" in boundary so that it will never be repeated.For more information, see the defi
FTP protocol specification provides multiple options for controlling file transfer and storage. You must make a choice in the following four aspects.1. File Type(1) The type of the ASCII code file is generally selected by default.(2) ebcdic file type this type of transmission method requires both ends of the ebcdic system.(3) image file type (also called binary) data transmission is presented as a bit stre
the number of bytes may be followed by one or more of the following suffixes:C =1, W =2, b =512, KB =1000, K =1024, MB =1000*1000, M =1024*1024, XM =mGB =1000*1000*1000, G =1024*1024*1024, and so in for T, P, E, Z, Y.
Each CONV symbol may be:

when you pick up the phone and talk, the phone converts your voice to electrical signals. A telephone is an interface between a person and a telecommunications network. You don't need to know the details of how your voice is converted, just know who you want to contact. In the same way, the socket hides the complex transmission of binary data and plays a role as a high-level interface.

We can see the meaning of the above command. We can note that the meaning of won't and don't depends on whether it is in binary transmission mode. If it is in ebcdic mode, and one side does not know any binary transfer command, if it receives the DOTRANSMIT-BINARY, it does not know what it is, so it returns won 'ttransmit-binary, if the default value for Won '
architecture defines the ccsid value of SDCS (Single Character Set), The ccsid value of MBCS (Multi-Character Set), and the mixed ccsid value of mixed single character multi-character set. The ccsid of multiple character sets is generally used in languages, such as Chinese, Japanese, and Korean. These languages have a large number of characters and cannot be represented by single-byte code values.
All sbcs ccsids define a similar basic set of characters, although they might define them in diff

1. Introduction to the SET command
Set command sets the running environment of SQL * Plus. The syntax FORMAT OF THE set command is:
SET system_variable value
The system_variable parameter represents the variable name, and the value parameter represents the variable value.
For example, set time on is a temporary operation and will be restored after logon is restarted.

You must be connected to a common user with the Create user privilege.2. The current database must be the root container database.3. The user name of a common user must be prefixed with "c##" or "c##" and contain a unique ASCII or EBCDIC character.4. In all containers the common user name mu

A control connection is a communication link that is built between the client protocol interpreter and the server protocol interpreter for exchanging commands and responses.2. A data connection is a full-duplex connection that transmits dat
