##官方文档对shmmax的设置解释，(文档 ID 567506.1)，我一般直接使用当前设置/sbin/sysctl -a | grep shm#Oracle Global Customer Support officially recommends a " maximum" for SHMMAX of "1/2 of physical RAM".#The maximum size of a shared memory segment is limited by the size of the available user address space. On 64-bit systems, this is a theoretical 2^64bytes. So the "theoretical limit" for SHMMAX is the amount of physical RAM that you have.However, to actually attempt to use such a value could potentially lead to a situation where no system memory is available for anything else.Therefore a more realistic "physical limit" for SHMMAX would probably be "physical RAM - 2Gb".#In an Oracle RDBMS application, this "physical limit" still leaves inadequate system memory for other necessary functions. Therefore, the common "Oracle maximum" for SHMMAX that you will often see is "1/2 of physical RAM". Many Oracle customers chose a higher fraction, at their discretion.#Occasionally, Customers may erroneously think that that setting the SHMMAX as recommended in this NOTE limits the total SGA.That is not true.Setting the SHMMAX as recommended only causes a few more "shared memory segments" to be used for whatever total SGA that you subsequently configure in Oracle.

##安装前检查脚本./runcluvfy.sh stage -pre crsinst -n rhel7-ora12c-ip21,rhel7-ora12c-ip22-fixup -verbose >> check.txt
##安装数据库软件和实例./gridSetup.sh
注意：12c R2强制安装GIMR，要求空间最低37G注：这里没有设置DNS，我把对DNS提示的错误全部忽略，物理内存要求大于8G，我忽略
##安装rdbms和instance和11G区别不大，正常安装即可
