Hi

Description
This parameter determines the type of pipe that is created by the pipe() system call. If set to the default value of zero, all pipes created by pipe() are normal HP-UX file-system pipes. If the value is 1, pipe() creates streams-based pipes and modules can be pushed onto the resulting stream.

If this parameter is set to a non-zero value, the pipemod and pipedev module and driver must be configured in file /stand/system.

Acceptable Values:
Minimum
0
Maximum
1
Default
0

Hi,

According to a common perception, setting it to 1 will actually slow the I/O of most database systems down.

Hope this helps. Regards.
