### 修改/etc/sysctl.conf
获取分页大小
getconf PAGE_SIZE
4096为4kb
shmmax用于定义单个共享内存段的最大值。设置应该足够大，能在一个共享内存段下容纳下整个的 SGA,建议值为多于物理内存的一半，一般取值大于 SGA_MAX_SIZE 即可
shmmax=32*1024*1024*1024*.64+(1G*1024*1024)=23063974389
vm.nr_hugepages=(32*1024*0.8*0.8)/2+10=10500 此值应略大于SGA
shmall 该参数控制可以使用的共享内存的总页数。 Linux 共享内存页大小为 4KB, 共享内存段的大小都是共享内存页大小的整数倍
shmall=shmmax(KB)/4 或shmmax(byte)/4096

mkdir -p $ORACLE_HOME
unzip LINUX.X64_193000_db_home.zip -d $ORACLE_HOME
/u01/app/oracle/product/19.3.0/db/runInstaller -silent -responsefile /soft/db_soft.rsp

Moved the install session logs to:
/u01/app/oraInventory/logs/InstallActions2021-08-18_04-12-36PM
注意已root用户执行上面的脚本
6.静默建库
mkdir -p /oradata/oadb/{datafile,tempfile,onlinelog,controlfile}
/u01/app/oracle/product/19.3.0/db/bin/dbca -silent -createDatabase -responseFile /soft/dbca.rsp
7.建库后参数调整
参数建议一项一项的调整，防止一下修改多个参数出问题混乱不好定位
1.开启归档
设置归档路径alter system set log_archive_dest_1='location=/oradata/arch';
正常关库，shutdown immediate;
启动至mount，开启归档alter database archivelog;
启动至open
2.调整内存SGA,PGA
https://blog.csdn.net/coco3600/article/details/100232524
pga_aggregate_limit PGA自动管理情况下，限制PGA的最大值，此数值must be between 9000M and 100000G,在自动 PGA 内存管理模式下， Oracle DB 尝试通过动态控制分配给工作区的 PGA 内存量遵从 PGA_AGGREGATE_TARGET 中指定的值。但是，有时候 PGA 内存使用量可能会因为以下原因超过 PGA_AGGREGATE_TARGET 指定的值
PGA_AGGREGATE_TARGET是一个目标，而不是一个限制
这里需要注意（SGA+PGA）小于80%的物理内存，不然在启动时会报下面的错误
PGA_AGGREGATE_TARGET specified is high
Errors in file /u01/app/oracle/diag/rdbms/oadb/oadb/trace/oadb_ora_25429.trc (incident=576025):

alter system reset memory_target scope=spfile sid='*';

alter system set sga_target=16G scope=spfile sid='*';
alter system set pga_aggregate_target=4G scope=spfile sid='*';
3.按需要调整控制文件,数据文件，redo,template文件的位置(注意权限问题)
--控制文件
mkdir -p /oradata/oadb/{controlfile,datafile,onlinelog,tempfile}
此时数据库状态为open
alter system set control_files='/oradata/oadb/controlfile/control01.ctl','/u01/app/oracle/product/19.3.0/db/dbs/control02.ctl' scope=spfile;
shutdown immediate;
mv /oradata/OADB/datafile/OADB/control01.ctl /oradata/oadb/controlfile/
mv /oradata/OADB/datafile/OADB/control02.ctl /u01/app/oracle/product/19.3.0/db/dbs/
启动数据库，startup;
查看控制文件新路径select name from v$controlfile;
--数据文件
查看当前文件位置select name from v$datafile;
正常关闭数据库，shutdown immediate;
移动数据文件
mv /oradata/OADB/datafile/OADB/users01.dbf /oradata/oadb/datafile/users01.dbf
mv /oradata/OADB/datafile/OADB/undotbs01.dbf /oradata/oadb/datafile/undotbs01.dbf
mv /oradata/OADB/datafile/OADB/system01.dbf /oradata/oadb/datafile/system01.dbf
mv /oradata/OADB/datafile/OADB/sysaux01.dbf /oradata/oadb/datafile/sysaux01.dbf
mv /oradata/OADB/datafile/OADB/temp01.dbf /oradata/oadb/tempfile/temp01.dbf
启动至mount,startup mount;
alter database rename file '/oradata/OADB/datafile/OADB/users01.dbf' to '/oradata/oadb/datafile/users01.dbf';
alter database rename file '/oradata/OADB/datafile/OADB/undotbs01.dbf' to '/oradata/oadb/datafile/undotbs01.dbf';
alter database rename file '/oradata/OADB/datafile/OADB/system01.dbf' to '/oradata/oadb/datafile/system01.dbf';
alter database rename file '/oradata/OADB/datafile/OADB/sysaux01.dbf' to '/oradata/oadb/datafile/sysaux01.dbf';
alter database rename file '/oradata/OADB/datafile/OADB/temp01.dbf' to '/oradata/oadb/tempfile/temp01.dbf';
--redo文件
查看当前文件位置
col MEMBER for a50
select GROUP#,MEMBER from v$logfile
正常关库，shutdown immeiate
移动文件
mv /oradata/OADB/datafile/OADB/redo*.log /oradata/oadb/onlinelog/
启动至mount,startup mount;
alter database rename file '/oradata/OADB/datafile/OADB/redo03.log' to '/oradata/oadb/onlinelog/redo03.log';
alter database rename file '/oradata/OADB/datafile/OADB/redo02.log' to '/oradata/oadb/onlinelog/redo02.log';
alter database rename file '/oradata/OADB/datafile/OADB/redo01.log' to '/oradata/oadb/onlinelog/redo01.log';
8.打补丁
以下均为oracle用户操作
--p32399816_190000补丁
可能会有这个Prerequisite check "CheckSystemCommandAvailable" failed.报错
root安装软件包即可yum search fuser,yum -y install psmisc.x86_64
查看补丁信息
/u01/app/oracle/product/19.3.0/db/OPatch/opatch lsinventory
关库后备份当前软件目录,shutdown immediate
tar -czvf /home/oracle/u01.tar.gz /u01/
解压Opatch包
mv $ORACLE_HOME/OPatch $ORACLE_HOME/OPatch.old
unzip /soft/p6880880_190000_Linux-x86-64.zip -d $ORACLE_HOME
解压补丁包
unzip /soft/p32399816_190000_Linux-x86-64.zip -d /soft/
打补丁
正常关闭数据库，shutdown immediate
cd /soft/32399816
/u01/app/oracle/product/19.3.0/db/OPatch/opatch apply 期间需要键入的一直输入y
Verifying environment and performing prerequisite checks...
Prerequisite check "CheckSystemCommandAvailable" failed.
The details are:

这个错误，安装psmic包即可
以upgrage模式启动数据库，startup upgrade
cd $ORACLE_HOME/OPatch
./datapatch -verbose
待此项结束
cd $ORACLE_HOME/rdbms/admin
sqlplus / as sysdba
@utlrp.sql
shutdown
--p32545008_190000补丁
解压补丁
unzip /soft/p32545008_190000_Linux-x86-64.zip -d /soft/
