1. 900929 - Linux: STORAGE_PARAMETERS_WRONG_SET and "mmap() failed"
Increase the value of the Linux kernel parameter "vm.max_map_count" to a sufficiently high number. For the sake of simplicity, we recommend the maximum possible value of 2147483647 (231-1).
To influence "vm.max_map_count", please edit the file /etc/sysctl.conf as the user "root". You can then activate the new parameter value using "sysctl -p":
vm.max_map_count=2147483647
Check of currently active setting:
# cat /proc/sys/vm/max_map_count
2147483647
If you need to increase the value of vm.max_map_count during ongoing SAP operations, we recommend that to be on the safe side you then restart the SAP system if terminations have already occurred. Otherwise, a restart is not necessary.
# SAP settings
kernel.sem=1250 256000 100 1024
vm.max_map_count=2000000 (see SAP Note 900929 for more information)
Please check SAP Note 941735 for recommendations on how to configure the kernel parameters kernel.shmmax and kernel.shmall and other memory related settings for 64bit systems. Run the command "sysctl --system" to activate the modified kernel parameters. You can use the command "ipcs -l --human" to check the current limits for shared memory, semaphores and message queues in the Linux kernel.

Linux kernel parameters
Some Linux kernel parameters have to be adjusted to meet the requirements of SAP software. To do this create a file /etc/sysctl.d/sap.conf with the following content (the valuies shown here are the required minimum values, higher values can be used as well):
