安装SAP在REHL76 系统要按SAP官网的说明配置
1. limits 配置
cat /etc/security/limits.conf|grep -v ^#|grep -v ^$: * soft core 65536 * hard rss 65536 * hard nproc 65536 * soft nproc 65536 oradev soft nproc 65536 oradev hard nproc 65536 oradev soft nofile 65536 oradev hard nofile 65536 oradev soft stack 65536 oradev hard stack 32768 oradev hard memlock 8000000 oradev soft memlock 8000000 oracle soft nproc 65536 oracle hard nproc 65536 oracle soft nofile 65536 oracle hard nofile 65536 oracle soft stack 65536 oracle hard stack 32768 oracle hard memlock 8000000 oracle soft memlock 8000000 @sapsys hard nofile 32800 @sapsys soft nofile 32800 @dba hard nofile 32800 @dba soft nofile 32800 cat /etc/security/limits.d/20-nproc.conf |grep -v ^#|grep -v ^$: * soft nproc unlimited root soft nproc unlimited
2 .系统参数配置
cat /etc/sysctl.conf|grep -v ^#|$: fs.aio-max-nr = 1048576 fs.file-max = 6815744 kernel.sem = 250 32000 100 128 net.ipv4.ip_local_port_range = 9000 65500 net.core.rmem_default = 262144 net.core.rmem_max = 4194304 net.core.wmem_default = 262144 net.core.wmem_max = 1048586 kernel.msgmni=1024 kernel.panic_on_oops = 1 kernel.sem = 1250 256000 100 1024 kernel.shmmax = 214748364800 kernel.shmall = 52428800 kernel.shmmni = 4096 vm.nr_hugepages = 2500 vm.max_map_count=2000000
3. DNS 配置(待更新)
