-bash: ulimit: pipe size: cannot modify limit: Invalid argument

The problem shown in the title occurs when switching from a root user to an Oracle user.

Solution: under Oracle, the vi editor opens the / etc/profile file.

There is a paragraph when configuring the file:

If [$USER = "oracle"]; then

If [$SHELL = "/ bin/ksh"]; then

Ulimit-p 16384

Ulimit-n 65536

Else

Ulimit-u 16384-n 65536

Fi

Fi

Add spaces on both sides of the "=" of the first and second lines, so you ok!

Pay attention to the spaces between parameters

The following is the meaning of each line

If the user is oracle, user shell= "/ bin/ksh"

Ulimit-p 16384 limits the size of the pipe buffer to 16384

Ulimit-n 65536 indicates that the maximum number of file descriptors that can be opened is 65536

Ulimit-u 16384 limits users to a maximum of 16384 processes
