prstat and ps -ef showing different username

PID USERNAME SIZE RSS STATE PRI NICE TIME CPU PROCESS/NLWP
4890 miscn 2917M 2899M cpu4 14 2 0:02.47 12% oracle/1
10496 ah_low 2949M 2925M cpu3 20 0 0:24.39 12% oracle/11
22932 oracle 2918M 2900M cpu1 59 -20 0:37.19 3.0% oracle/1

then when I do a ps -ef | grep 10496 , it shows :

$ ps -ef | grep 10496
oracle 10496 1 12 Oct 30 ? 28:29 ora_snp3_MMI2K

As you can see, prstat show PID 10496 username is ah_low, but when i do a ps -ef , it shows 10496 is run by oracle.

anyone got a link or document why this happpen?

thanks.
