12c打补丁前置检查

备份文件，可以不做，因为文件可能很大，如果可以备份整个安装文件。

1.check

grid：

% /u01/app/12.1.0/grid/OPatch/opatch prereq CheckConflictAgainstOHWithDetail -phBaseDir /home/software/27010872/26910974 

% /u01/app/12.1.0/grid/OPatch/opatch prereq CheckConflictAgainstOHWithDetail -phBaseDir /home/software/27010872/26925218 

% /u01/app/12.1.0/grid/OPatch/opatch prereq CheckConflictAgainstOHWithDetail -phBaseDir /home/software/27010872/26925311 

% /u01/app/12.1.0/grid/OPatch/opatch prereq CheckConflictAgainstOHWithDetail -phBaseDir /home/software/27010872/26983807 

oracle：

% /u01/app/oracle/product/12.1.0/db_1/OPatch/opatch prereq CheckConflictAgainstOHWithDetail -phBaseDir /home/software/27010872/26925311

% /u01/app/oracle/product/12.1.0/db_1/OPatch/opatch prereq CheckConflictAgainstOHWithDetail -phBaseDir /home/software/27010872/26925218

\3. os space check

grid:

3.1.    Create file /tmp/patch_list_gihome.txt with the following content: 

% vi /tmp/patch_list_gihome.txt

/home/software/27010872/26910974 

/home/software/27010872/26925218 

/home/software/27010872/26925311 

/home/software/27010872/26983807 

3.2. 

% /u01/app/12.1.0/grid/OPatch/opatch prereq CheckSystemSpace -phBaseFile /tmp/patch_list_gihome.txt

oracle:

3.3.    Create file /tmp/patch_list_dbhome.txt with the following content: 

% vi /tmp/patch_list_dbhome.txt

/home/software/27010872/26925311 

/home/software/27010872/26925218 

3.4. 

% /u01/app/oracle/product/12.1.0/db_1/OPatch/opatch prereq CheckSystemSpace -phBaseFile /tmp/patch_list_dbhome.txt 

\4. backup 相关文件，最好整个安装目录

打补丁步骤如下：

oracle

/u01/app/oracle/product/12.1.0/db_1/bin/srvctl stop home -o /u01/app/oracle/product/12.1.0/db_1 -s /home/oracle/patch20180123 -n hn-lbs-5885-01

root

/u01/app/12.1.0/grid/crs/install/rootcrs.pl -prepatch

如果出现crs报错rollback mode问题（滚动升级，二节点）

/u01/app/12.1.0/grid/crs/install/roothas.sh -unlock

grid

$ /u01/app/12.1.0/grid/OPatch/opatch apply -oh /u01/app/12.1.0/grid -local /home/software/27010872/26925218

$ /u01/app/12.1.0/grid/OPatch/opatch apply -oh /u01/app/12.1.0/grid -local /home/software/27010872/26910974

$ /u01/app/12.1.0/grid/OPatch/opatch apply -oh /u01/app/12.1.0/grid -local /home/software/27010872/26983807

$ /u01/app/12.1.0/grid/OPatch/opatch apply -oh /u01/app/12.1.0/grid -local /home/software/27010872/26925311

oracle

$ /home/software/27010872/26925218/custom/scripts/prepatch.sh -dbhome /u01/app/oracle/product/12.1.0/db_1

$ /u01/app/oracle/product/12.1.0/db_1/OPatch/opatch apply -oh /u01/app/oracle/product/12.1.0/db_1 -local /home/software/27010872/26925218

$ /u01/app/oracle/product/12.1.0/db_1/OPatch/opatch apply -oh /u01/app/oracle/product/12.1.0/db_1 -local /home/software/27010872/26925311

$ /home/software/27010872/26925218/custom/scripts/postpatch.sh -dbhome /u01/app/oracle/product/12.1.0/db_1

root

/u01/app/12.1.0/grid/rdbms/install/rootadd_rdbms.sh

root

两个节点都打完再执行下面步骤

/u01/app/12.1.0/grid/crs/install/rootcrs.pl -postpatch

打完补丁后(二节点滚动升级)

/u01/app/12.1.0/grid/crs/install/rootcrs.sh -patch

oracle

/u01/app/oracle/product/12.1.0/db_1/bin/srvctl start home -o /u01/app/oracle/product/12.1.0/db_1 -s /home/oracle/patch20180123 -n hn-lbs-5885-01

su - oracle

srvctl start database -d lbs1

srvctl start database -d lbs2

srvctl start database -d lbs3

srvctl start database -d lbs4

srvctl start database -d test

12c特有步骤如下：

SQL> alter pluggable database all open;

cd $ORACLE_HOME/OPatch

./datapatch -verbose

select patch_id,action,status from dba_registry_sqlpatch; 

回滚（如果打补丁失败，进行回滚操作）

root

/u01/app/12.1.0/grid/OPatch/OPatch/opatchauto rollback /home/software/27010872

手动

oracle

$ /u01/app/12.1.0/grid/bin/srvctl stop home -o /u01/app/12.1.0/grid -s /home/oracle/patch20180123 -n hn-lbs-5885-01

root

\# /u01/app/12.1.0/grid/crs/install/rootcrs.sh -prepatch -rollback

grid

/u01/app/12.1.0/grid/OPatch/opatch nrollback -local -id 26925218,26910974,26983807,26925311 -oh /u01/app/12.1.0/grid

oracle

$ home/software/27010872/26925218/custom/scripts/prepatch.sh -dbhome /u01/app/oracle/product/12.1.0/db_1

$ /u01/app/oracle/product/12.1.0/db_1/OPatch/opatch nrollback -local -id 26925218,26925311 -oh /u01/app/oracle/product/12.1.0/db_1

$ home/software/27010872/26925218/custom/scripts/postpatch.sh -dbhome /u01/app/oracle/product/12.1.0/db_1 

root

/u01/app/12.1.0/grid/rdbms/install/rootadd_rdbms.sh 

\# /u01/app/12.1.0/grid/crs/install/rootcrs.sh -postpatch -rollback

oracle

$ /u01/app/oracle/product/12.1.0/db_1/bin/srvctl start home -o /u01/app/oracle/product/12.1.0/db_1 -s /home/oracle/patch20180123 -n hn-lbs-5885-01 

注意：

如果出现crs报错rollback mode问题（同11g不同之处）

/u01/app/12.1.0/grid/crs/install/roothas.sh -unlock

打完补丁后（同11g不同之处）

/u01/app/12.1.0/grid/crs/install/rootcrs.sh -patch
