● For hardware with 8 IvyTown sockets and larger, the maximum number of processes for the sapsys

group is not sufficient. This causes the the installation of SAP HANA to fail. The solution is to create

the /etc/security/limits.d/99-sapsys.conf file:

@sapsys soft nproc unlimited

By default, RHEL for SAP HANA is configured in such a way as to prevent "fork bombs". The fact that the

group sapsys can now create an unlimited number of processes can be a potential security issue.

● The occurrence of SAP HANA crashes is entirely unrelated to operating system mechanisms. We can

therefore omit the application crash and core file handling of the operating system.

○ The abrt service which handles application crashes needs to be disabled completely.

# chkconfig abrtd off

# chkconfig abrt-ccpp off

# service abrtd stop

# service abrt-ccpp stop

○ The same applies with core file creation. To disable core dumps for all users, open /etc/security/

limits.conf, and add the following line:

* soft core 0

* hard core 0
