Problem: How to keep a standby database in continuous managed recovery
without having to maintain an open terminal session. (Version 8.1.7.2)

When you execute the following...
-------------------------------------------------------------- 
SQL> RECOVER MANAGED STANDBY DATABASE;
-------------------------------------------------------------- 
...SQL*Plus does not return a prompt and the database is in continuous
recovery BUT... as soon as you exit the session, recovery discontiues and
the logs are nolonger automagically applied. "No problem," I said, "I'll
just wrap it in a shell script and launch it in the background." Doesn't
work and it appears SQL*Plus is a misbehaving process. (Linux)

So then I tried nohup:
-------------------------------------------------------------- 
$ nohup sqlplus "/ as sysdba" @managed_recov.sql & 
[1] 23412 
$ nohup: appending output to 'nohup.out' 
[1]+ Exit 127 nohup sqlplus "/ as sysdba" @managed_recov.sql 
-------------------------------------------------------------- 
The managed_recov.sql script contains this one line: 
RECOVER MANAGED STANDBY DATABASE; 
This works but it does not persist as a background process- it terminates
when I hit enter or leave the terminal session. I think it terminates
because SQL*Plus is misbehaving. What do you think? 

So with a little help from a *nix geek I did this...
-------------------------------------------------------------- 
sqlplus "/ as sysdba" @managed_recov.sql </dev/null &>standby.log &
-------------------------------------------------------------- 
...presto chango, it works- standard I/O is OK and running in the
background. The standby DB is in continuous recovery and I can shutdown my
PC and go home and managed recovery just keeps on running. Cool.

Is there a better way to do this? I submitted a TAR but OWS hasn't been any
help. Doesn't it seem lame that Oracle gives the "RECOVER MANAGED STANDBY
DATABASE" command but is unable to provide a means to implement it without
requiring the terminal session to remain open?
