I may say load of nonsense as just got home not too well and very tired so forgive me...
What I see is what you say give what you expected for an output is a command line:
Code:
 ps -ef|grep pmon_$ORACLE_SID|grep -v grep

What is it made of? I see 3 processes, and yes nothing wrong there so you get what is expected but
looking at your if, what do you think is the condition?


So what about replacing your if by :
Code:
if  [ -n  "$(ps -ef|grep pmon_$ORACLE_SID|grep -v grep)" ]

or the correct variant ( sorry can't test, and in bed now...)

Addendum:
That is what I would do in ksh...

zgrep

ZGREP(1)						      General Commands Manual							  ZGREP(1)

NAME

       zgrep - search possibly compressed files for a regular expression

SYNOPSIS

       zgrep [ grep_options ] [ -e ] pattern filename...

DESCRIPTION

       Zgrep  invokes  grep  on  compressed  or  gzipped  files.   These  grep	options  will  cause  zgrep  to  terminate  with  an  error  code:
       (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*).  All other options specified are passed directly to grep.  If no file is specified,  then  the
       standard input is decompressed if necessary and fed to grep.  Otherwise the given files are uncompressed if necessary and fed to grep.

       If the GREP environment variable is set, zgrep uses it as the grep program to be invoked.

EXIT CODE

       2 - An option that is not supported was specified.
