CentOS7.6静默安装19C实例脚本 ORA-27125 [FATAL] [DBT-10322]

脚本：

dbca -silent -createDatabase -templateName General_Purpose.dbc -gdbname test -sid test -characterSet AL32UTF8 -TOTALMEMORY 4096 -STORAGETYPE FS -DATAFILEDESTINATION /oracle/oradata/tbomtest/ -sysPassword oracle -systemPassword oracle

--------------------------------------------------------------------------需要注意的是19c的实例名不能添加"_"下划线，要不然会报错

上边脚本实例名跟下边实操的实例名不是一个！

alphanumeric characters:字母数字字符来自有道翻译，下面的报错就是我实例名加上下划线，去掉下划线就可以正常运行了

[oracle@tldbompx03 ~]$ dbca -silent -createDatabase -templateName General_Purpose.dbc -gdbname tbom_px -sid tbom_px -characterSet AL32UTF8 -TOTALMEMORY 4096 -STORAGETYPE FS -DATAFILEDESTINATION /oracle/oradata/tbom_px/ -sysPassword oracle -systemPassword oracle

这里ORA-27125 - Unable to create shared memory segment error 共享内存段错误，一般调整/etc/sysctl.conf中的最大共享内存kernel.shmmax、kernel.shmmni就可以，sysctl -p使参数生效

没有分配kernel.shmmax、kernel.shmmni内存创建实例失败

重新分配内存

shmall 是全部允许使用的共享内存大小，shmmax 是单个段允许使用的大小。这两个可以设置为内存的 80%

kernel.shmmax=例如 24G 内存，24*1024*1024*1024*80% = 20615843021
kernel.shmall=kernel.shmmax(20615843021)/4k=5033165
