I'm not sure with AIX but from my understanding you don't need to do this in Unix. After a bit of time your RAM will be released when the program that was using it no longer is running.

See this info:

Why does the "fre" field from vmstat sometimes show lots of free
RAM pages?

This will happen after an application that used a lot of RAM via
"working" storage (not NFS storage, and not disk file or "persistent"
storage) exits. When RAM pages that were used by working storage (a
program's stack and data area) are no longer needed, there is no need to
leave them around. AIX completely frees these RAM pages. The time to
access these pages versus a RAM page holding a "sync'd" mapped file is
almost identical. Therefore, there is no need to periodically "flush" RAM.
