memory problem with Sybase after ios upgrade
I recently installed hpux 11.0 on a K370 server. The server previously ran 10.20. We are running Sybase 11.92. When Sybase starts up now an error appears:
kernel Locking shared memory into physical memory.
kernel os_create_region: can't allocate 777211904 bytes.
kernel kbcreate: couldn't create kernel region.
kernel kistartup: could not create share.
unlockable memory set to 0.
Any ideas???

Re: memory problem with Sybase after ios upgrade
Hi,
1.You can try to install all the required patches on HP-UX using custom patch manager.
2. try to set the parammeter maxdziz to max value that is
0x7b03A000 (2 GB)
Hope this helps ,

Re: memory problem with Sybase after ios upgrade
Hi ernest
Check glance to see memory usage
swapinfo -tam to check swapinfo
Have a look at the following link regarding unlockable_mem parameter
http://forums.itrc.hp.com/cm/QuestionAnswer/1,,0xc6fb5e938a10d6118ff40090279cd0f9,00.html
Also
Whats your buffer cache set to
sysdef | grep nbuf
sysdef | grep bufpages
You can allow the system to use dynamic buffer caching by setting them both to 0 then manage them through the settings
dbc_min_pct
dbc_max_pct
general advise is to set them to 5 and 15
This will be a percentage value of your systems memory
Also have a look at the following regarding other tunable parameters
http://docs.hp.com/hpux/onlinedocs/os/KCparams.OverviewAll.html

Steve

Re: memory problem with Sybase after ios upgrade
Hi ernest,
it seems that your configured shared memory
shmmax is to small and sybase is not able to allocate the total memory configured in SERVERNAME.cfg
