So there I was, reading on the internet about having set echo on for RMAN and started to incorporate it into RMAN scripts.
It was a waste of time since it is not needed according to my test cases.
Lesson learned is that don’t trust what is provided to you without a complete test case.
Here’s the test case.
[oracle@lax:db01]/home/oracle
$ cat bk.rman
connect target;
run {
allocate channel d4 device type disk format '/tmp/%d_%I_%T_%U' maxopenfiles 1;
backup tablespace system;
}
exit
$ nohup rman @bk.rman > rman.log 2>&1 &
[1] 3115
[oracle@lax:db01]/home/oracle
$
[1]+ Done nohup rman @bk.rman > rman.log 2>&1
[oracle@lax:db01]/home/oracle
$ cat rman.log
nohup: ignoring input
