Oracle Database Upgrade Guide
Upgrade Oracle Database 19c Non-CDB to Oracle AI Database 26ai PDB using AutoUpgrade
Source Database: Oracle Database 19c (19.3 Non-CDB) >>> to
Target Database: Oracle AI Database 26ai (23.26.1) <<<<
Upgrade Method: AutoUpgrade
Operating System: Oracle Linux
1. Objective
This document describes the procedure for upgrading an Oracle 19c Non-CDB database into an Oracle AI Database 26ai Pluggable Database (PDB) using Oracle AutoUpgrade.
2. Environment
Parameter Value
Source Database ORCL
Source Version 19.3.0.0
Target Version Oracle AI Database 26ai (23.26.1)
Source Oracle Home /u01/app/oracle/product/19.0.0/db_1
Target Oracle Home /u01/app/oracle/product/26.0.0/dbhome_1
Target CDB cdb26i
Target PDB ORCL
3. Install Oracle AI Database 26ai Software
Set Environment
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/26.0.0/dbhome_1
export PATH=$ORACLE_HOME/bin:$PATH
export ORACLE_SID=cdb26i
export SOFTWARE_DIR=/home/oracle
export ORA_INVENTORY=/u01/app/oraInventory
Create Oracle Home
mkdir -p $ORACLE_HOME
Extract Software
cd $ORACLE_HOME
pwd
/u01/app/oracle/product/26.0.0/dbhome_1
unzip -oq ${SOFTWARE_DIR}/LINUX.X64_2326100_db_home.zip
unzip -oq ${SOFTWARE_DIR}/LINUX.X64_2326100_db_home.zip
Install Software
./runInstaller \
-ignorePrereq \
-waitforcompletion \
-silent \
-responseFile ${ORACLE_HOME}/install/response/db_install.rsp \
installOption=INSTALL_DB_SWONLY \
UNIX_GROUP_NAME=oinstall \
INVENTORY_LOCATION=${ORA_INVENTORY} \
ORACLE_HOME=${ORACLE_HOME} \
ORACLE_BASE=${ORACLE_BASE} \
installEdition=EE \
OSDBA=dba \
OSBACKUPDBA=dba \
OSDGDBA=dba \
OSKMDBA=dba \
OSRACDBA=dba
After installation completes, execute:
root.sh
as the root user.
4. Create the Target 26ai Container Database
Create the database storage location.
mkdir -p /u01/app/oracle/oradata/cdb26i
Run DBCA to create database
from Oracle home
dbca -silent -createDatabase \
-templateName General_Purpose.dbc \
-gdbname cdb26i \
-sid cdb26i \
-responseFile NO_VALUE \
-characterSet AL32UTF8 \
-sysPassword sys \
-systemPassword sys \
-createAsContainerDatabase true \
-numberOfPDBs 0 \
-databaseType MULTIPURPOSE \
-memoryMgmtType auto_sga \
-totalMemory 1536 \
-storageType FS \
-datafileDestination "/u01/app/oracle/oradata/cdb26i" \
-redoLogFileSize 50 \
-emConfiguration NONE \
-ignorePreReqs
5. Resolve ORADISM Permission Issue
If DBCA fails with:
DBT-10011 Incorrect ownership/permissions detected for oradism
Login as root and execute:
cd $ORACLE_HOME/bin
chown root:oinstall oradism
chmod 4750 oradism
Verify:
ls -l oradism
Expected:
-rwsr-x--- root oinstall
Re-run DBCA after correcting the permissions.
6. Update AutoUpgrade Utility
Backup the existing JAR.
cd $ORACLE_HOME/rdbms/admin
mv autoupgrade.jar autoupgrade.jar.$(date +%F)
Download the latest version.
wget https://download.oracle.com/otn-pub/otn_software/autoupgrade.jar
Copy the new JAR into:
$ORACLE_HOME/rdbms/admin
7. Configure Archive Log Mode
Login as SYSDBA.
sqlplus / as sysdba
ALTER SYSTEM SET db_recovery_file_dest_size=20G;
ALTER SYSTEM SET db_recovery_file_dest='/u01/app/oracle/fast_recovery_area26ai';
ALTER SYSTEM SET db_create_file_dest='/u01/app/oracle/oradata/cdb26i';
SHUTDOWN IMMEDIATE;
STARTUP MOUNT;
ALTER DATABASE ARCHIVELOG;
ALTER DATABASE OPEN;

8. Create AutoUpgrade Configuration File
Example:
global.global_log_dir=/home/oracle/upgrade
upg1.sid=ORCL
upg1.target_cdb=cdb26i
upg1.source_home=/u01/app/oracle/product/19.0.0/db_1
upg1.target_home=/u01/app/oracle/product/26.0.0/dbhome_1
upg1.target_pdb_name=orcl
upg1.start_time=NOW
upg1.upgrade_node=grid26
upg1.run_utlrp=yes
upg1.timezone_upg=yes
upg1.target_version=26
upg1.restoration=no
9. Run AutoUpgrade Analysis
Execute:
$ORACLE_HOME/jdk/bin/java \
-jar $ORACLE_HOME/rdbms/admin/autoupgrade.jar \
-config /home/oracle/upgrade/config.txt \
-mode analyze
Monitor jobs:
lsj
If analysis reports:
FLASH_RECOVERY_AREA_SETUP
ARCHIVE_MODE_ON
Configure the FRA and enable ARCHIVELOG mode, then rerun the analysis until all prechecks succeed.
10. Start the Upgrade
Execute:
$ORACLE_HOME/jdk/bin/java \
-jar $ORACLE_HOME/rdbms/admin/autoupgrade.jar \
-config /home/oracle/upgrade/config.txt \
-mode deploy
Monitor progress using:
lsj
Typical stages include:
PRECHECKS
PREFIXUPS
DRAIN
DBUPGRADE
NONCDBTOPDB
POSTCHECKS
POSTFIXUPS
POSTUPGRADE
SYSUPDATES
