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.

4 GB. In this 4G space, the user space occupies 3G (0x00000000 to 0 xbfffff), and the core space occupies 1G (0xc0000000 to 0 xffffffff ). Such an allocation policy is called 3G/1G allocation.
The specific allocation method is as follows:
1. 0 GB-1 GB User space-Used for text/code and brk/sbrk allocations (malloc uses brk for small chunks)
