Hello.
I made changes for parameters abap/heap_area_nondia, abap/heap_area_total, abap/heap_area_dia but when i checked values i recieved message:
<b>abap/heap_area_dia 3000000000
E:abap/heap_area_dia greater than maximum 2147483647
ztta/roll_area 6500000
abap/heap_area_nondia 3000000000
E:abap/heap_area_nondia greater than maximum 2147483647
abap/heap_area_total 4000000000
E:abap/heap_area_total greater than maximum 2147483647 </b>
whats whrong?
Hi,
Change these values so that they don't cross the maximum values using rz10.
Then restart the cluster for the changes to take affect.
regards and reward with good points of helpful

hello Satya,
we're using SAP BW 3.5 , patch sapkw35018, sap kernel 64-bit , hp-ux 11.11, oracle 920.
memory 8 Gb
swap 20 Gb
em/initial_size_MB = 4092
ztta/roll_extension = 2000000000 (2 Gb)
We need use more memory, because encountered dumps:
SYSTEM_NO_ROLL, TSV_TNEW_PAGE_ALLOC_FAILED.
I have enlarged em/initial_size_MB to 5120 and ztta/roll_extension to 3000000000(3 Gb) and trying restart instance. But instance not started. Then i return value to back instance are started.
regards,
Denis
Satya,
could you tell me how clean share memory segment ?
is ipc/shm_psize_10 and ipc/shm_psize_40 parameters of hp-ux kernel?
and what consequence of checking ipc/shm_psize_10 and ipc/shm_psize_40 :
first - change parameters
second - check by running sappfpar
third - restart instance?
regards,
Denis
Hi Denis,
ipc/shm_psize_10 and ipc/shm_psize_40 is parameter in SAP Instance profile. They are kind of shared memory segment. So, if you increase any memory parameter, they need to be adjusted accordingly..
Steps:
1. Increase em/initial_size_MB and ztta/roll_extension from RZ10 inside SAP and activate the profile
2. Stop SAP instance (stopsap r3)
3. then logon as <SID>adm and go to Profile directory (/sapmnt/<SID>/profile)
4. run from HPUX level: sappfpar check pf=<Your SAP instance profile name>. this should show some errors/warnings and suggest a new value for Shared memory key 10 and 40. Adjust those value for ipc/shm_key_10 and 40 accordingly
5. Check for active shared memory segment ipcs | grep sap
6. delete the active shared memory segments (if any) via ipcrm -m <number from ipcs output> -s <number from ipcs output> (this step is optional) More info see 'man ipcrm' under HPUX
7. restart SAP
Cheers !!

Hello Satya,
I've made settings of parameters:
ztta/roll_extension = 3000000000
em/initial_size_MB = 5120
but when checked profile instance recieved message :
<b>ztta/roll_extension grater than 2147483647</b>.
Where is the restrictions 2147483647 of ztta/roll_extension ?
and <b>sappfpar</b> about too:
for example i have:
<b> Key: 10 Pool
Size configured.....: 124000000 ( 118.3 MB)
Size min. estimated.: 119695426 ( 114.1 MB)
Advised Size........: 122000000 ( 116.3 MB)
Key: 40 Pool for database buffers
Size configured.....: 114000000 ( 108.7 MB)
Size min. estimated.: 108975040 ( 103.9 MB)
Advised Size........: 112000000 ( 106.8 MB)
</b>
what does it mean? Should i set up ipc/shm_psize_10 = 116.3 MB and
ipc/shm_psize_40 = 106.8 MB?
regards,
Denis
Hi Denis,
It's strange. For 6.40 kernel this ztta/roll_extension should not have any more 2GB limit...
Anyway, could you check if your HP-UX kernel paramaters are set properly as per recommendation from note: 172747. That might cause the bottleneck.
However, as you can increase em/initial_size_MB, I propsoe to increase it even further (e.g. 7168 ) and keep ztta/roll_extension as 2GB as now.
That already should help you...
regarding ipc/shm_psize_* looks your configured value s already bigger than they advise. So, no changes would be required.
Cheers !!

Hi Denis,
You need to increase atleast....
<b>shmmax = >=17,179,869,184
maxdsiz_64bit >=17,179,869,184</b>
msgmap should take from msgtql which needs to be set at 4096.
pls go thru note 172747 and set all the parameter accordingly.
you will then need to regenerate the kernel and reboot the machine.
Cheers !!

Hello Satya,
We can't change parameters of hp-ux kernel, because strong reglament there is, i.e. it's work of other men - specialist of hp-ux.
But, you now, this some strange, we''ve occupied 3GB оf extended memmory howewer and what is more we've occupied 5Gb. although during checking profile instance (tr. RZ10) we are getting message: ztta/roll_extension grater than 2147483647.
Regards,
Denis
Hi Denis,
You have to ask your HPUX administrators to prepare Unix server as required by SAP
I can't see why you cannot increase ztta/roll_extension. From 6.40 kernel (64-bit) it's up to 16,384 petabytes. For 32-bit the limit is at 2 GB.
I guess you first make sure you are using indeed 64-bit kernel and then there is no limitation imposed by OS.
Cheers !!
Satya.
