UNIX PIPES:- The UNIX domain sockets (UNIX Pipes) are typically used when communicating between two processes running in the same UNIX machine. UNIX Pipes usually have a very good throughput. They are also more secure than TCP/IP, since Pipes can only be accessed from applications that run on the computer where the server executes. When starting a server using UNIX Pipes, you must reserve a unique listening name (inside that machine) for the server, for instance, 'soliddb'. Because UNIX Pipes handle the UNIX domain sockets as standard file system entries, there is always a corresponding file created for every listened pipe. In solidDB®'s case, the entries are created under the path /tmp Our example listening name 'soliddb' creates the directory/tmp/solunp_SOLIDDB and shared files in that directory. The /tmp/solunp_ is a constant prefix for all created objects while the latter part ('SOLIDDB' in this case) is the listening name in upper ca...
