I am not going to add  output of all commands. The output should looks like as above.

2)

Shut down all instances and listeners associated with the Oracle home that you are updating.

Stop a PDB from Oracle home:

alter pluggable database KARDBPDB close immediate;

srvctl stop database -d KARDBTST

srvctl status database -d KARDBTST

Database is not running.

Stop Listener from GI Home

srvctl stop  listener -l LISTENER

srvctl status listener -l LISTENER

Listener LISTENER is enabled

Listener LISTENER is not running

Stop ASM

srvctl stop asm -f

srvctl status asm

ASM is not running.

3)

As root user execute the following command.

You have following options

 i) To patch only the GI Home

 <GI_HOME>/OPatch/opatchauto apply <UNZIPPED_PATCH_LOCATION>/31750094 -  oh <GI_HOME>

ii) To patch oracle_home

  opatchauto apply <UNZIPPED_PATCH_LOCATION>/31750094 -oh <oracle_home1_path>

 iii) Patching Oracle Home and Grid Home togather:

 As root user, execute the following command on each node of the cluster:

 # <GI_HOME>/OPatch/opatchauto apply <UNZIPPED_PATCH_LOCATION>/31750094

I am going to apply the path for both grid home and oracle home together.

NOTE: make sure that the Clusterware is running:

crsctl stat res -t

If it is not running, you need to start it as follow.

crsctl start has

export PATH=$PATH:$GRID_HOME/OPatch
$GRID_HOME/OPatch/opatchauto apply $DOWNLOAD_PATCH/31750094

Post-Installation Instructions

Single/Multitenant (CDB/PDB) DB

sqlplus / as sysdba

startup

alter pluggable database all open;

quit

cd $ORACLE_HOME/OPatch

./datapatch -verbose

Any databases that have invalid objects need to execute utlrp.sql run

For example:

cd $ORACLE_HOME/rdbms/admin

sqlplus /nolog

SQL> CONNECT / AS SYSDBA

SQL> @$ORACLE_HOME/rdbms/admin/utlrp.sql

-- You can check valid or invalid objects with the following command.

set pagesize 250;

col STATUS format a20;

col COMP_NAME format a35;

select COMP_NAME, version, status from dba_registry;

Patch 31668898 - Oracle JavaVM Component Release Update 12.2.0.1.201020

p31668898_122010_Linux-x86-64.zip

For a Non Oracle RAC environment, shut down all databases and listeners associated with the Oracle home that you are updating.

From Oracle_home.

Normally no need to stop ASM. You need to just stop the DB and Listener

alter pluggable database KARDBPDB close immediate;

srvctl stop database -d KARDBTST

srvctl stop  listener -l LISTENER

export PATH=$PATH:/usr/ccs/bin

#$ORACLE_HOME/OPatch/opatch apply $DOWNLOAD_PATCH/31668898

Post installation Steps.

startup upgrade

alter pluggable database all open upgrade;

cd $ORACLE_HOME/OPatch

./datapatch -verbose
