Without additional data it is hard to suggest.

Different AIX-versions (especially 4.x to 5.x but others too) have different ways of memory management. Tell us your OS version as detailed as possible.

Please show the output of (taken at - roughly - the same moment):

Code:
vmstat -tw 1 10
vmstat -v
ioo -a
vmo -a
lsps -a
svmon -G

You mentioned a running Oracle database: how big is your SGA or - if you run several instances - each SGA respectively? Which version of Oracle are you running?

swapon

SWAPON(8)						      System Manager's Manual							 SWAPON(8)

NAME

       swapon - specify additional device for paging and swapping

SYNOPSIS

       swapon -a
       swapon name ...

DESCRIPTION

       Swapon  is  used to specify additional devices on which paging and swapping are to take place.  The system begins by swapping and paging on
       only a single device so that only one disk is required at bootstrap time.  Calls to swapon normally occur in the system multi-user initial-
       ization file /etc/rc making all swap devices available, so that the paging and swapping activity is interleaved across several devices.

       Normally, the -a argument is given, causing all devices marked as ``sw'' swap devices in /etc/fstab to be made available.

       The  second  form gives individual block devices as given in the system swap configuration table.  The call makes only this space available
       to the system for swap allocation.

SEE ALSO

       swapon(2), init(8)

FILES

       /dev/[ru][pk]?b	   normal paging devices

BUGS

       There is no way to stop paging and swapping on a device.  It is therefore not possible to make use of devices which may be dismounted  dur-
       ing system operation.

       swapon is not implemented in 2.11BSD.
