Your code is now escaping special characters and printing server name. But it is also printing below line after each server's output.

Code:
 /<Oracle_home>/ohs/bin/odl_rotatelogs -h:/<app_Home>/config/OHS/ohs1/component_events.xml_ohs1
/<Oracle_home>/ohs/bin/odl_rotatelogs -h:/<app_Home>/config/OHS/ohs1/component_events.xml_ohs2
 serverA1 awk server=serverA1

How do I suppress that?

Or, if you quote EOF all expansion is disabled, this does leave you to resolve server on the remote side perhaps you could use hostname like this:

Code:
ssh $server "bash -s" << "EOF"
ps -ef | awk -v server=$(hostname -s) '/[r]otate/ && /config/ {print server, $8" "$10}'
EOF

Code:
server=$(hostname -s)

is resolving hostname to local hostname.

Below code is working.. but I am not sure how its working, can you explain?
Code:
 
 ps -ef | awk -v "server=$server" '/[r]otate/ && /config/ {print server, \$8" "\$10}'

it is filtering out
Code:
serverA1 awk server=serverA1

That's the awk process itself. It should not be matched due to the [r] brackets. Are you sure you used above command pipe?

Add a 1 between closing brace and closing quote and post the result.

The quotes around "EOF" are important, they stop this local-side expansion of the $() command substitution eg:

Code:
$ hostname -s
MyPC

$ ssh MyServer <<EOF
   echo $(hostname -s)
EOF
MyPC

$ ssh MyServer <<"EOF"
  echo $(hostname -s)
EOF
MyServer
