You should work with your DB2 DBA and your AIX admin to reduce the usage of filesystem cache. Your maxperm is set to 90% (of 110 Gb). That's way too high. Is PO the only application running on that LPAR? Because 110 Gb seems quite large for a single LPAR.
Use concurrent I/O to improve DB2 database performance
