Code:
chk_refresh=`cat $LOGDIR/Erefresh.log|grep "ORA-"` if [[ -z $chk_refresh ]];  then echo "The $ORACLE_SID ERfrsh done, NO ERRORS on $(date)"|mailx -s "Refresh" Bob.Ross@NG.com else echo "The $ORACLE_SID ERfrsh done, ERRORS. on $(date)"|mailx -s "Refresh Errors" Bob.Ross@NG.com fi

I think RudiC will have discovered one basic error but i don't understand why you have opted for backticks for your chk_refresh=`cat $LOGDIR/Erefresh.log|grep "ORA-"` yet use $(date) in the "echo" part.

Also there should also be a semi-colon just before "else" and "fi"!
You really should structure your code and thus these would be picked straight up.

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.
