I was able to do it in another way
Code:
cat fileA | while read CLIENT DB POLICY SCHEDULE DATE TIME
do
  if ( grep -w "$DB" fileB | grep -w "$CLIENT" | grep -w "$POLICY" | grep -w "$SCHEDULE" )
  then echo $DB $CLIENT $POLICY $SCHEDULE $DATE $TIME >> fileC
  else echo $DB $CLIENT $POLICY $SCHEDULE $DATE $TIME >> fileD
  fi
done

now situation becomes more complicated; we need to apply 2 more conditions Smilie

INITIAL SETUP
base condition
values from column 1 to 5 of fileA should match with fileB Smilie
;
if matching, put it on fileC and if not fileD

NOW
values from column 1 to 5 of fileA should match with fileB
and
values of column 6 & 7 of fileA are greater than fileB
;
if matching, put it on fileC and if not fileD Smilie


i wrote one script

Code:
cat fileA | while read STATUS CLIENT DB POLICY SCHEDULE DATE TIME ; do
  if  ( grep -w "$DB" fileB | grep -w "$CLIENT" | grep -w "$POLICY" | grep -w "$SCHEDULE" ) ; if ( $6 < "'$DATE'"  )  ;  if ( $7 < "'$TIME'" )
  then echo $STATUS $DB $CLIENT $POLICY $SCHEDULE $DATE $TIME >> fileC
  else echo $STATUS $DB $CLIENT $POLICY $SCHEDULE $DATE $TIME >> fileD
  fi
done


but its erroring out as below Smilie

line 14: syntax error near unexpected token `done'

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. AUTHOR
