Code:
while [[ 1 -eq 1 ]]
do
   check=$(psu | egrep -v "ps|grep" | grep -ic ASP)
   if [[ $check -eq 0 ]]
   then
      ASP_SH 101
      sleep 10
   else 
      echo "Process is running"
   fi
done

What is 1> 2? When is 1 ever greater than 2? The syntax is -gt.
What is ASP_SH?

Did you define ASP_SH as a function?

Use [[ 1 -eq 1 ]].

Did you remove all the semi colons?

Updated and tested:

Code:
root@ms:/>cat /tmp/a
#!/usr/bin/ksh

while [[ 1 -eq 1 ]]
do
   check=$(ps -ef | egrep -v "ps|grep" | grep -ic ksh93)
   if [[ $check -ge 1 ]]
   then
      echo "Process is running."

   else
      echo "Process is not running."

   fi

   sleep 10

done
root@ms:/>/tmp/a
Process is running.
Process is running.
