集群数据库都是两节点两个用户打补丁
19c是root用户的打的补丁
补丁包：
p34130714_190000_Linux-x86-64.zip
解压
unzip p34130714_190000_Linux-x86-64.zip
chown -R grid:oninstall 34130714cat readme.html 查看需要的opatch版本12.2.0.1.30
ORACLE_HOME/OPatch#./opatch version 查看当前opatch版本12.2.0.1.17
适用高版本Opatch:p6880880_122010_Linux_x86-64.zip(scp上)
unzip p6880880_122010_Linux_x86-64.zip
grid:mv $ORACLE_HOME/Opatch $ORACLE_HOME/OPatchbak
/u01/app/soft#:mv Opatch /u01/app/19.0.0.0/grid
chown -R grid:oninstall OPatch
chown -R oracle:oninstall OPatch使用响应文件打补丁：(root用户)
打grid补丁：($ORACLE_HOME/OPatch)
./opatchauto apply /oracle/soft/29698727 -oh /oracle/app/product/11.2.0/grid打oracle补丁：($ORACLE_HOME/OPatch)
./opatchauto apply /oracle/soft/29698727 -oh /oracle/app/product/11.2.0/db
补丁报错方案：
检查权限是否正确
lsof /u01| grep lib将占用lib进程杀掉，尽量在dbca之前补丁，建库后补丁还需进行重新编译对象，根据补丁内的readme.html
文件表空间无法扩展（是否需要改）
报错：

oracle原厂给出的解决方案
you can set the diskgroup attribute compatible.rdbms to a value greater than 10.1 with alter diskgroup command ( v$asm_attribute ), but the file size limit will be the old limit for the existing files. The new value of compatible.rdbms will be effective for the new files only.
必须把compatible.rdbms参数大小设为10.1以上，但是对旧有数据文件无效
×××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××
该数据库参数设置
select name,value from v$asm_attribute where name='compatible.rdbms';
NAME VALUE
-------------------- ------------------------------
compatible.rdbms 10.1.0.0.0
asmcompatible.rdbms 10.1.0.0.0根据远程检查 asm磁盘组的compatible.rdbms 为10.1.0.0.0
设置大于10.1将能够保证文件大小最大128TB，可以使用如下命令修改磁盘组属性，但是退的这是个不可回操作
ASMCMD > setattr -G data compatible.rdbms 10.2.0.0.0dbca模板建库
