SAP 64bit Linux application server (Linux on Power) memory config issues

Question

Hello Everyone,
Let me give some background. I have been tasked with replacing our AIX6.1 SAP application server with new Linux on Power servers (SLES11SP3)
Our current production BW application servers (AIX) are running fine given their current setup. We are fine implementing the same size of the AIX systems on the new Linux systems, but we now have more room to grow in the fur, however when I tried to implement the Linux server using the same memory sizing I am getting runtime errors: "TSV_TNEW_PAGE_ALLOC_FAILED" with a specific user created program and process chain. The AIX servers do not run into this issue running the exact same program. When this process runs, it utilizes 3 BTC process for the program.
Using the note 941735, I have tried to correctly setup the system using STD memory implementation, however I have a feeling that I am missing something or setup something incorrectly which is causing the above issue. Looking in ST02 here is the SAP buffer parameters for two of the systems. Perhaps someone might notice something that I am not see or point me in the right direction. Please let me know if more parameters from the profile are needed. Thanks!

Yes sapconf has been installed. sapconf however only sets the kernel settings.
I was able to resolve the issue by having Zero Admin tool using 'es/implementation = map' and setting the PHYS_MEMSIZE to the desired amount. Then commenting out all the values that are defaulted in the 32bit version of the memory management guide for linux and let it size many of the values. Then I simply copied those from st02. I updated the profile with those values to override default for  'es/implementation = std' and commented out PHYS_MEMSIZE as it is not needed. In a nut shell, the following parameters were updated.
es/implementation = std
em/address_space_MB = 4096
em/blocksize_KB = 4096
em/initial_size_MB = 14320
em/max_size_MB = 14326
rdisp/PG_MAXFS = 131072
rdisp/PG_SHM = 16384
rdisp/ROLL_MAXFS = 131072
rdisp/ROLL_SHM = 131072
ztta/roll_area = 6500352
ztta/roll_extension = 4000000000
ztta/roll_extension_dia = 4000000000
ztta/roll_extension_nondia = 4000000000
ztta/roll_first = 1
