How to Patch oracle 18c/19c Non RAC (Single Instance) database

NOTE: Starting from 18c Oracle calls Patch Set Update (PSU), as Release Update (RU).
S
tep1> Download the Patch
Download the patch to be applied from oracle support

 Step2> Transfer the patch on the sever and unzip it using unzip utility
Note: I am using OCT2019 PSU(RU) together with OJVM patch
p30112122_180000_Linux-x86-64.zip  <= OCT DB PSU (DB RU)
p30133603_180000_Linux-x86-64.zip  <= OCT JAVA Patch

 $unzip p30112122_180000_Linux-x86-64.zip -d /OCT_2019_PSU/
$unzip p30133603_180000_Linux-x86-64.zip -d /OCT_2019_PSU/

 Step3> Verify Utility the Opatch version
OPatch Utility:
You must use the OPatch utility version as described in README file for the patch. Oracle recommends that you use the latest released OPatch version for 18c, which is available for download from My Oracle Support patch 6880880 by selecting the 18.0.0.0.0 release.
$export PATH=$PATH:$ORACLE_HOME/OPatch
$opatch version
OPatch Version: 12.2.0.1.17
OPatch succeeded.

Step4> Perform Patch Conflict Detection and Resolution
export ORACLE_HOME=/u01/app/product/18c/db_home
export PATH=$PATH:$ORACLE_HOME/OPatch
cd /OCT_2019_PSU/30112122/
opatch prereq CheckConflictAgainstOHWithDetail -ph ./

cd /OCT_2019_PSU/30133603/
opatch prereq CheckConflictAgainstOHWithDetail -ph ./

 Logs Provided Below "Conflict Resolution Run Log"

 Step5> Apply the patch
To apply the patch shut down all the database listener from the OH you are going to patch
Apply DB PSU
as oracle user
$cd /OCT_2019_PSU/30112122/$opatch apply

 Apply Java Patch

$cd /OCT_2019_PSU/30133603/
$opatch apply

logs for DB patch and JAVA patch provided below 
"DB Patch Run Log"
"JAVA Patch Run Log"

Step6> Start the oracle processes (DB + Listener)
sqlplus /nolog
SQL> Connect / as sysdba
SQL> startup
SQL> alter pluggable database all open;
SQL> quit
$lsnrctl start LISTENER01

 Step7> Load Modified SQL Files into the Database

cd $ORACLE_HOME/OPatch
./datapatch -verbose
Logs provided below "Datapatch Run Log"

 Step8> Run utlrp.slq to compile the invalid Objects
cd $ORACLE_HOME/rdbms/admin
sqlplus /nolog
SQL> CONNECT / AS SYSDBA
SQL> @utlrp.sql

How to Switch Log File from All Instances in RAC

<<Back to Oracle RAC Main Page Switch The Log File of All Instances in Oracle RAC. In many cases you need to switch the logfile of the database. You can switch logfile using alter system switch logfile command but if you want to switch the logfile from all the instances you need to execute the command on all the instances individually and therefore you must login on all the instances. You can avoid this and switch logfile of all instances by just running the below command from any of the instance in RAC database SQL> ALTER SYSTEM SWITCH ALL LOGFILE;   System altered.

Note: Oracle does not recommend deleting keystore file (ewallet.p12) that belongs to a database. If you have multiple keystores, you can choose to merge them rather than deleting either of them.
