Checking Oracle user Process in unix

hi List,
I am checking some oracle users (user1 and user2) processes (sunsolaris) using ps -ef|grep.

$ps -ef|grep sqlplus
 user1 26671 5991 0 10:36:35 pts/20 0:00 sqlplus sys   me 27415 25766 0 11:47:36 pts/17 0:00 grep sqlplus  user2 27408 26250 0 11:46:27 pts/7 0:00 sqlplus tlcrsdev/tlcrsdev_at_crsprod @/home/dcook/TIPS/BDE/v1/tlcrs_load_tables/lo

checking oracle process...for user1
$ps -ef|grep 26671
  user1 26671 5991 0 10:36:35 pts/20 0:00 sqlplus sys   oracle 26672 26671 0 10:36:38 ? 0:00 oracleTERAPROD (DESCRIPTION=(LOCAL=YES)(ADDRESS=(PROTOCOL=beq)))

checking oracle process .. for user2 (running script for shell programupdating  table)
$ps -ef|grep 27408

   dcook 27408 26250 0 11:46:27 pts/7 0:00 sqlplus tlcrsdev/tlcrsdev_at_crsprod @/home/dcook/TIPS/BDE/v1/tlcrs_load_tables/lo

My question is for user2 why I am not able to see the oracle process.

can somebody tell me what is happening here? am i missing something.
