Home -> Community -> Mailing Lists -> Oracle-L -> RE: Compressing Rman Disk Backups
Lex,
that interface is available in 9i also. but it *only* supports sending rman commands and rman output of those commands. I was looking for piping the backup set to gzip to compress it.
thanks for the reply!!

from the 10g documentation:
RMAN Pipe Interface
The pipe interface is invoked by using the PIPE command-line parameter. RMAN uses two private pipes: one for receiving commands and the other for sending output. The names of the pipes are derived from the value of the PIPE parameter. For example, you can invoke RMAN with the following command:
% rman PIPE abc TARGET SYS/oracle_at_trgt
RMAN opens the two pipes in the target database: ORA$RMAN_ABC_IN, which RMAN uses to receive user commands, and ORA$RMAN_ABC_OUT, which RMAN uses to send all output back to RMAN.
All messages on both the input and output pipes are of type VARCHAR2.
Note that RMAN does not permit the pipe interface to be used with public pipes, because they are a potential security problem. With a public pipe, any user who knows the name of the pipe can send commands to RMAN and intercept its output.

At one point a couple years ago I met the lead developer for RMAN, and mentioned this. He agreed that it should check for the existence of a named pipe rather than clobbering it, and expressed the intention to fix this defect in a future version. Has anyone checked to see if this still happens in 10g?
