Hana Installation Error - Cannot create initial topology

[Former Member]

Hi dear experts, I'm getting the following problem trying to install Hana on SLES 11 on a VMWare. You can find attached the error log, as you can see I'm using a laptop but I think the memory amount doesn't has to affect  the installation because I'm setting --ignore=check_diskspace,check_min_mem.

In addition I'm getting the same error when I use a VM with 30gb RAM.

Can anybody help me?

Hi Damian,

The issue appears to be that hdbnsutil is running OOM during the -initTopology process. As stated by Amerjit, 7132 GB is too small for HANA. The OOM occurs not because of the check but because there just is not enough memory available:

Damian,

I see you have now decided to try with REV82 as opposed to your other attempt with REV91.

You really are asking for nothing but trouble when trying to install HANA on a virtual machine with 7132MB of memory. That's 7132MB for both the o/s and HDB !!!!!!

Anyway, the following OSS note also covers a SIG 11 during install but I see in your install you have already passed that step (check the permissions mentioned in the note anyway). What you are hitting is a OOM which really doesn't surprise me. The nameserver itself needs ~8GB.
