echo "dmdba soft nofile 65536" >> /etc/security/limits.conf
echo "dmdba hard nproc 10240" >> /etc/security/limits.conf
echo "dmdba soft nproc 10240" >> /etc/security/limits.conf
echo "dmdba hard core unlimited" >> /etc/security/limits.conf
echo "dmdba soft core unlimited" >> /etc/security/limits.conf
echo "dmdba hard data unlimited" >> /etc/security/limits.conf
echo "dmdba soft data unlimited" >> /etc/security/limits.conf
echo "dmdba hard fsize unlimited" >> /etc/security/limits.conf
echo "dmdba soft fsize unlimited" >> /etc/security/limits.conf
echo "root hard nofile 65536" >> /etc/security/limits.conf
echo "root soft nofile 65536" >> /etc/security/limits.conf
echo "root hard nproc 10240" >> /etc/security/limits.conf

麒麟v10 SP1版本检查RemoveIPC参数设置

检查RemoveIPC参数设置，要求为no ：
systemctl show systemd-logind | grep -i removeipc
参数修改
如果不是no，用以下方法调整：
修改/etc/systemd/logind.conf配置文件中的RemoveIPC参数，将#注释去掉，并修改yes为no，
重启服务
systemctl daemon-reload;
systemctl restart systemd-logind
./dminit path=/home/dmdba/dmdbms/data EXTENT_SIZE=32 PAGE_SIZE=32 LOG_SIZE=2048 CASE_SENSITIVE=1 CHARSET=1 LENGTH_IN_CHAR=1 ARCH_FLAG=1
./dm_service_installer.sh -t dmserver -dm_ini /home/dmdba/dmdbms/data/DAMENG/dm.ini -p DMSERVER
