If not already exists a „not used“ Oracle Home. create a new one..

dbsw_install dbs 19.EE 19.20
(19.EE is our 19.16 Prepared Image) 

Now it will create our new Home in 
/app_oracle/product/dbs/19.20

(it will prompt that you have to make an root commando, please do that)

Replace the OPatch utility with the newest Version

mv $ORACLE_HOME/OPatch $ORACLE_HOME/OPatch_old
unzip /app_oracle/local/tools/p6880880_210000_Linux-x86-64.zip -d $ORACLE_HOME/

Oracle recommends to use the autoupgrade Tool to switch the home and install all correctly: You have to create an cfg to use autoupgrade correctly.

cd /app_oracle/local/tools/autoupgrade.jar

vi autoupgrade_patch_CDB.cfg

patch_C10P.log_dir=/app_oracle/log
patch_C10P.sid=C10P1
patch_C10P.source_home=/app_oracle/product/dbs/19.EE
patch_C10P.target_home=/app_oracle/product/dbs/19.20
patch_C10P.start_time=NOW
patch_C10P.run_utlrp=yes

Okay last Check – autoupgrades brings an „analyze“ with it

$ORACLE_HOME/jdk/bin/java -jar autoupgrade.jar \
-config autoupgrade_patch_CDB.cfg \
-mode analyze

cat /app_oracle/cfgtoollogs/autoupgrade/cfgtoollogs/upgrade/auto/status/status.log

looks good -- everthing fine

Okay start the upgrade- now the database is a while unavailable – if it is a singe instance


$ORACLE_HOME/jdk/bin/java -jar /app_oracle/autoupgrade/autoupgrade.jar \
-config /app_oracle/autoupgrade/autoupgrade_patch_CDB.txt \
-mode deploy

cat /app_oracle/cfgtoollogs/autoupgrade/cfgtoollogs/upgrade/auto/status/status.log

Within our Sphinx Environment now its needed to change some things


cd /app_oracle/local/etc
Copy our oraenv specific shellscript too 

cp oraenv-dbs-19.EE.sh oraenv-dbs-19.20.sh

change the .EE with the current version
vi oraenv-dbs-19.20.sh -- change .EE mit .20

Relink oraenv-default.sh

rm oraenv-default.sh
ln -s oraenv-dbs-19.20.sh oraenv-default.sh

Switch to the current environment an take a look
chenv c10p
sqlplus "sys/sx123 as sysdba"

Also change listener.ora to run on 
ORACLE_HOME=/app_oracle/product/dbs/19.20
instead of 19.EE

-- 19.20.0.0 -- all is good

Worksfine, it can be used for x Databases in one Script
