format using TAR. The first tape archive begins storage (tar #0) from the physical start of the tape. The next step is the tar #1, and so on.Tape Device name on Unix /dev/rmt/0 or/DEV/RMT/1 or/dev/rmt/[0-127]: A generic tape device name on Unix. The tape is automatically inverted back. /dev/rmt/0n: Featur

tags and block sizes Figure 01: tape file tag Each tape device can store multiple backup files. The tape backup file is created using commands such as cpio, tar, and dd. At the same time, tape devices can be opened, written, and closed by a variety of programs. You can store several backups (Tape files) to a physical tape. There is a "tape file tag" between each tape file ". This indicates the end of a tape file on a physical tape and the start of another file. You need to use the mt command t

At the same time, tape devices can be opened, written, and closed by a variety of programs. You can store several backups (tape files) onto a physical tape. There is a "tape file mark" between each tape file. This is used to indicate the end of a tape file on a physical tape and the beginning of another file. You need to use

indicate the end of a tape file on a physical tape and the beginning of another file. You need to use the MT command to locate the tape (fast forward, rewind, and Mark).How the data on the tape is storedAll data is stored continuously in a continuous tape storage format using TAR. The first tape archive begins storage (tar #0) from the physical start of the tape. The next step is the tar #1, and so on.Tape Device name on Unix/dev/rmt/0 or/DEV/

From the user's point of view, any unix device can be seen as a file. Therefore, you can "open" an appropriate tape drive file to write data to the file. Although it sounds too simple, this is the actual situation. The Unix system treats every device as a file and processes it like a common file, so that the operations on the file and the device are as unified as possible. From the user's point of view, the use of devices is the same as that of General files. Therefore, the most effective way to

a look at the file compression method. With File compression, we can try to avoid the DMP file size exceeding the limit of 2 GB. We use the Unix pipeline technology, the specific steps are as follows, 1. Start the compress process to read data from the pipeline and output the data to the disk file. $ Mknod/tmp/exp_pipe P $ Compress 2. exp to MPs queue. $ Exp file =/tmp/exp_pipe... IMP is similar. Let's take a look at the method to directly import exp to the tape. $ Exp file =/dev/

given the physical layout of the database, it is useful to create a table space and users in advance. 2, if export use is incremental/cumulative mode, you need to set up a table space, users, data files.
