1. The current RHEL version is 7.1 and the kernel is
uname -r 3.10.0-123.el7.x86_642. Before the OS upgrade stop the HAS and disable the auto start on reboot.
crsctl stop has crsctl disable has CRS-4621: Oracle High Availability Services autostart is disabled.3. Comment the entries in oracle-ohasd.service
cat /etc/systemd/system/oracle-ohasd.service # Copyright (c) 2014, Oracle and/or its affiliates. All rights reserved. # # Oracle OHASD startup [Unit] #Description=Oracle High Availability Services #After=syslog.target [Service] #ExecStart=/etc/init.d/init.ohasd run >/dev/null 2>&1 </dev/null #Type=simple #Restart=always [Install] #WantedBy=multi-user.target graphical.target4. Upgrade the RHEL 7 OS. Kernel and RHEL7 version after the upgrade are
uname -r 3.10.0-327.el7.x86_64 cat /etc/redhat-release Red Hat Enterprise Linux Server release 7.2 (Maipo)5. Uncomment the entires in oracle-ohasd.service file and enable auto start of HAS
crsctl enable has CRS-4622: Oracle High Availability Services autostart is enabled.Until this point the steps are common for both 11.2.0.4 and 12.1.0.2.
Relinking 11.2.0.4 GI and Oracle Homes
1.Relinking Oracle Home as oracle user. Make sure the relink binary in the PATH is from Oracle home
which relink /opt/app/oracle/product/11.2.0/dbhome_4/bin/relinkRun relink all
cd $ORACLE_HOME/bin ./relink all writing relink log to: /opt/app/oracle/product/11.2.0/dbhome_4/install/relink.logAt the end of the relink the log file have the following
test ! -f /opt/app/oracle/product/11.2.0/dbhome_4/bin/oracle ||\ mv -f /opt/app/oracle/product/11.2.0/dbhome_4/bin/oracle /opt/app/oracle/product/11.2.0/dbhome_4/bin/oracleO mv /opt/app/oracle/product/11.2.0/dbhome_4/rdbms/lib/oracle /opt/app/oracle/product/11.2.0/dbhome_4/bin/oracle chmod 6751 /opt/app/oracle/product/11.2.0/dbhome_4/bin/oracle2. Relinkning GI Home
Set ORACLE_HOME=$GI_HOME
As root unlock the GI Home. Using the RHEL 7 provided perl version will result in following error

As root unlock the GI Home by using the $GI_HOME/crs/install/roothas.sh. Unlike 11.2.0.4 there are no issues in unlocking GI home in 12c
