1.Stop the CRS managed resources running from DB homes. If this is a GI Home environment, as the database home owner execute:
su - oracle
/u01/app/oracle/product/11.2.0/db_1/bin/srvctl stop home -o /u01/app/oracle/product/11.2.0/db_1 -s /home/oracle/db_state.txt -n xxxx1

2.Run the pre root script. If this is a GI Home, as the root user execute:
su - root
/u01/app/grid/perl/bin/perl /u01/app/grid/crs/install/rootcrs.pl -unlock

3.Apply the CRS patch
su - grid
/u01/app/grid/OPatch/opatch napply -oh /u01/app/grid -local /u01/software/31718723/29938455
/u01/app/grid/OPatch/opatch napply -oh /u01/app/grid -local /u01/software/31718723/29509309
/u01/app/grid/OPatch/opatch napply -oh /u01/app/grid -local /u01/software/31718723/31537677

4.Run the pre script for DB component of the patch
su - oracle

/u01/software/31718723/29938455/custom/server/29938455/custom/scripts/prepatch.sh -dbhome /u01/app/oracle/product/11.2.0/db_1

5.Apply the DB patch
su - oracle
/u01/app/oracle/product/11.2.0/db_1/OPatch/opatch napply -oh /u01/app/oracle/product/11.2.0/db_1 -local /u01/software/31718723/29938455/custom/server/29938455
/u01/app/oracle/product/11.2.0/db_1/OPatch/opatch apply -oh /u01/app/oracle/product/11.2.0/db_1 -local /u01/software/31718723/31537677

6.Run the post script for DB component of the patch
su - oracle
/u01/software/31718723/29938455/custom/server/29938455/custom/scripts/postpatch.sh -dbhome /u01/app/oracle/product/11.2.0/db_1

7.Run the post script
su - root
/u01/app/grid/rdbms/install/rootadd_rdbms.sh
/u01/app/grid/perl/bin/perl /u01/app/grid/crs/install/rootcrs.pl -patch

8.Start the CRS managed resources that were earlier running from DB homes
su- oracle
/u01/app/oracle/product/11.2.0/db_1/bin/srvctl start home -o /u01/app/oracle/product/11.2.0/db_1 -s /home/oracle/db_state.txt -n xxxx1

/u01/app/oracle/product/11.2.0/db_1/OPatch/opatch lsinv
/u01/app/grid/bin/crsctl stat res -t
