Fresh Install: os_create_region: can't allocate x bytes

[Former Member]

Hi,

I'm attempting a fresh install to get to grips with installation and configuration of ASE16, and I'm repeatedly coming across this issue.

I'm following the guide for Installing on Linux, and I've run through all the pre-install steps and configuration right up to running the console installer, but it always fails at seemingly the last hurdle, running the server.

Here's the error message I've received:

os_create_region: can't allocate 247144448 bytes

The error message according to my research is related to my "kernel.shmmax" property, but I've tried boosting it to ensure there's enough memory allocated (running "/sbin/sysctl -p" shows the correct values) without any effect.

In additon, I've run "ipcs -l" which gives me a shared memory report, which states that I should have > 8GB shared memory able to be allocated, so this is clearly not a memory issue, there must be something else going on.

Any help would be greatly appreciated.

Here's the full log (/opt/sap/ASE-16_0/install/ASE.log):

I found the source of the issue.

In my question, I mentioned that I had increased the memory as per the guide, but what I didn't say is that all this is running on a VirtualBox machine.

I hadn't given enough memory to the server itself within VirtualBox, therefore, despite me saying I wanted to allow 8GB of shared memory, the server it was running on only had 1GB on it. I increased this, re-ran the installer and it all works correctly now.
