*** It is recommended that the /usr/sap/<SID>/SYS/exe/run directory be copied to /usr/sap/<SID>/SYS/exe/backup_run before replacing the kernel ***
1. Log on to the appropriate server as <sid>adm.
2. Double check that the SAP instance, SAPOSCOL, and SAP<SID>_00 services are stopped.
3. To apply the new kernel patch to a R/3 instance, copy the new files into usr\sap\<SID>\SYS\exe\run directory. If prompted for overwrites, say yes to all.
4. After the new kernel has been copied make sure that the following file ownerships are correct:
All files in /usr/sap/<SID>/SYS/exe/run <sid>adm
/usr/sap/<SID>/SYS/exe/run/saposcol root
/usr/sap/<SID>/SYS/exe/run/br* ora<sid>
/usr/sap/<SID>/SYS/exe/run/sapdba ora<sid>
5. After the successful completion of the kernel patch, you may bring the instance back up and log off the server.
