DB2 FOR LUW / DB2FORLUW / A50 - DB2

The virtual shared memory allocation for FMP memory on UNIX was 
increased to 256MB on DB2 version 9.5. (the documentation will 
be corrected as it indicates a smaller value for non-AIX 
platforms).  It may be desirable to set DB2_FMP_COMM_HEAPSZ to 
override the default setting to a lower value for 
small-footprint instances on consolidated systems, and this 
should be honored as documented (as it is when setting a value 
higher than 256MB - 65536 4K pages).  This is more relevant for 
operating systems where the virtual shared memory allocation 
counts towards some resource or limit - swap and shared memory 
limits on Solaris, HP-UX, or shmall shared memory virtual limit 
on Linux.

* USERS AFFECTED:                                              * 
* Systems with small instance memory footprints (typically     * 
* consolidated systems) AND where virtual shared memory limits *

increase resource (swap on Solaris or HP-UX) or virtual shared 
memory limit (Solaris, HP-UX, Linux)
