Description of problem:
Configure kernel params by creating a file /etc/sysctl.d/sap.conf with the following content:

# SAP settings
vm.max_map_count = 2147483647
kernel.pid_max = 4194304

Version-Release number of selected component (if applicable):
8.4 for SAP on AWS only

How reproducible:
always

Additional info:
SAP note 2772999

Comment 1 Irina Gulina 2021-05-12 17:55:58 UTC

When fixed, the following commands should return the corresponding output: 

# sysctl vm.max_map_count
vm.max_map_count = 2147483647
# sysctl kernel.pid_max
kernel.pid_max = 4194304
# sysctl kernel.sem
kernel.sem = 32000 1024000000 500 32000

Hi,

Since the issue described in this bug should be resolved (VERIFIED), could you please close this bug with resolution 'CURRENTRELEASE' if this bug got fixed ?

If the fix for this is not released yet, check if this will ever get fixed. In case of a negative answer then please change it as WONTFIX.

If there's anything else to be done on this BZ, if it's still active, not released yet and we actually intend to release it, then please ignore my message.

Please note: for those bugs which are not included in errata, please add 'TestOnly' keyword, and those bugs with 'TestOnly' keyword will be closed automatically after GA.
TestOnly: Use this when there is no code delivery involved, or for use when code is already upstream and will be incorporated automatically to the next release for testing purposes only.

Thank you.
