Status: Verified
GOAL:
Running 64 bit version of Progress and cannot increase Database Buffer Pool (-B)
GOAL:
Cannot increase -B parameter even though not hitting limits for Progress 64 bit shared memory storage
FACT(s) (Environment):
HP-UX 11.0
Progress 9.0B
Progress 9.1x
FIX:
The amount of memory you have available for Database Buffers (-B) on HP-UX can be limited by not having pseudo-swap reservation enabled in the kernel. By not having this parameter configured, the database broker process is limited to device swap space on disk.
To enable this kernel parameter, change swapmem_on to 1 instead of 0 in your kernel settings.
The following information was taken from docs.hp.com and provides information regarding the swapmem_on kernel parameter:
swapmem_on is a kernel parameters which can be used to enable or disable pseudo-swap reservation on an HP-UX machine. This kernel parameter by default is set to 1 which indicates pseudo-swap reservation is enabled. Pseudo-swap, is space in system memory considered as available virtual memory space in addition to device swap space on disk.
On systems that have massive amounts of installed RAM and large disks or disk arrays, there may be situations where it would be advantageous to not be restricted to the allocated device swap space.
