count multiple objects in shell script

Hi all:

Trying to count the number of oracle instances on HPUX 11.23 - using ksh. I have multiple instances running and I would like to have a count for how many processes for each instance. Example, run the 'ps -efu oracle' command and for each instance increment a counter. So I am looking for
INT1=# INT2=# INT3=# ... INTn=#

I keep thinking a 'do-while' or some type of 'while' loop but I am missing something, somewhere...

Many thanks!

Do you have pstree?

Here's an example:

$ pstree | grep mingetty
|-6*[mingetty]

This shows that there are 6 instances of mingetty running on my system.
