oracle19c rac补丁升级及回退（19.3-＞19.22）_oracle 19c opatch回退

一、准备工作及打补丁

1.备份当前集群的所有文件（两个节点都要做）

cd /u01/app/19.3.0/grid/bin/
crsctl stop crs
tar -zcvf /u01/app.tar.gz /u01/app
/u01/app/19.0.0/grid/bin/
crsctl start crs

2.解压压缩包并替换opatch(两节点都要做)

# 替换GI的OPatch
su - grid
cd /u01/app/19.3.0/grid
mv OPatch OPatch.bak20
su - root
cd /soft
chown -R grid:oinstall /soft
unzip p6880880_190000_Linux-x86-64.zip
 
chown -R grid:oinstall /soft
su - grid -c "unzip -q -o /soft/p6880880_190000_Linux-x86-64.zip -d /u01/app/19.3.0/grid"
su - grid -c "unzip -q /soft/p35940989_190000_Linux-x86-64.zip -d /soft"
chown -R oracle:oinstall /soft
su - oracle -c "unzip -q -o /soft/p35943157_190000_Linux-x86-64.zip -d /u01/app/oracle/product/19.3.0/db"
cp -r OPatch /u01/app/19.3.0/grid/
chown grid:oinstall -R /u01/app/19.3.0/grid/OPatch
# 替换DB的OPatch
cd $ORACLE_HOME
mv OPatch/ OPatch_bak20
su root
chown -R oracle:oinstall /soft
cp -r /soft/OPatch /u01/app/oracle/product/19.3.0/db
chown -R oracle:oinstall /u01/app/oracle/product/19.3.0/db
su - oracle
cd $ORACLE_HOME/OPatch
./opatch version 

3.验证ORACLE清单信息（两节点）

su - root
chown grid:oinstall -R /soft
su - grid
$ORACLE_HOME/OPatch/opatch lsinventory > /soft/grid_patch.txt
$ORACLE_HOME/OPatch/opatch lsinv -detail -oh $ORACLE_HOME >> /soft/grid_patch.txt
$ORACLE_HOME/OPatch/opatch lspatches >> /soft/grid_patch.txt
 
su - root
chown oracle:oinstall -R /soft
su - oracle
$ORACLE_HOME/OPatch/opatch lsinventory > /soft/oracle_patch.txt
$ORACLE_HOME/OPatch/opatch lsinv -detail -oh $ORACLE_HOME >> /soft/oracle_patch.txt
$ORACLE_HOME/OPatch/opatch lspatches >> /soft/oracle_patch.txt
 

4.冲突检测（两节点）

# grid用户下
cd /u01/app/19.3.0/grid/OPatch/ 
 
$ORACLE_HOME/OPatch/opatch prereq CheckConflictAgainstOHWithDetail -phBaseDir /soft/35940989/33575402
 
$ORACLE_HOME/OPatch/opatch prereq CheckConflictAgainstOHWithDetail -phBaseDir /soft/35940989/35943157
 
$ORACLE_HOME/OPatch/opatch prereq CheckConflictAgainstOHWithDetail -phBaseDir /soft/35940989/35956421
 
$ORACLE_HOME/OPatch/opatch prereq CheckConflictAgainstOHWithDetail -phBaseDir /soft/35940989/35967489
 
$ORACLE_HOME/OPatch/opatch prereq CheckConflictAgainstOHWithDetail -phBaseDir /soft/35940989/36115038

# oracle用户下
su - oracle
cd /u01/app/19.3.0/grid/OPatch
 
$ORACLE_HOME/OPatch/opatch prereq CheckConflictAgainstOHWithDetail -phBaseDir /soft/35940989/35943157
 
$ORACLE_HOME/OPatch/opatch prereq CheckConflictAgainstOHWithDetail -phBaseDir /soft/35940989/35967489

5.空间检测

su - root
chown grid:oinstall -R /soft
#grid用户下
vim /soft/patch_list_gihome.txt
 
/soft/35940989/35943157
/soft/35940989/35967489
/soft/35940989/35956421
/soft/35940989/36115038
/soft/35940989/33575402
 
$ORACLE_HOME/OPatch/opatch prereq CheckSystemSpace -phBaseFile /soft/patch_list_gihome.txt
 
 
su - root
chown oracle:oinstall -R /soft
#  oracle用户下
vim /soft/patch_list_dbhome.txt
 
/soft/35940989/35943157
/soft/35940989/35967489
 
$ORACLE_HOME/OPatch/opatch prereq CheckSystemSpace -phBaseFile /soft/patch_list_dbhome.txt

6.应用修补程序补丁（两节点）

/u01/app/19.3.0/grid/OPatch/opatchauto apply /soft/35940989 -analyze

7.打补丁（双节点）

su - root
# 如果节点2没有这个文件可以从节点1拷过去
scp -r /u01/app/oraInventory/ContentsXML/oui-patch.xml root@p19c02:/u01/app/oraInventory/ContentsXML
chmod 777 /u01/app/oraInventory/ContentsXML/oui-patch.xml
cd /soft/35940989/35967489/files/bin/
chmod 777 *

# 执行以下命令应用补丁（采用的是 grid和db一起打的方式）
/u01/app/19.3.0/grid/OPatch/opatchauto apply /soft/35940989
 
 
# 另外一个节点选择分开打
/u01/app/19.3.0/grid/OPatch/opatchauto apply /soft/35940989 -oh /u01/app/19.3.0/grid
/u01/app/oracle/product/19.3.0/db/OPatch/opatchauto apply /soft/35940989 -oh /u01/app/oracle/product/19.3.0/db

8.将修改的sql文件应用到库中

# 一个节点执行就行
cd $ORACLE_HOME/OPatch
./datapatch -sanity_checks
./datapatch -verbose

二、回退补丁

su - root
cd /
/u01/app/19.3.0/grid/OPatch/opatchauto rollback /soft/35940989
