Upgrading to Oracle Database 19c (Non-CDB) - 11g to 19c

Oracle Database 19c, Oracle Database Exam Prep, Oracle Database Preparation

This article provides an overview of upgrading an existing non-CDB database to Oracle 19c. Upgrades can be very complicated, so you must always read the upgrade manual, and test thoroughly before considering an upgrade of a production environment.

This article also includes the conversion of the upgraded database to a pluggable database. You don't have to do this step if you want a non-CDB instance.

Remember, 19c is essentially 12.2.0.3, so the possible upgrade options will be similar to those described in upgrading to Oracle Database 12c.

◉ Assumptions

This article is focused on upgrading a non-CDB database. If your starting point is a database using the multitenant architecture, you should be reading one of the following articles instead.

Multitenant : Upgrading to Oracle Database 19c

Multitenant : Upgrade a PDB using Unplug/Plugin

This article assumes your source database is of a version supported for direct upgrade to 19c.

11.2.0.4, 12.1.0.2, 12.2.0.1, 18

In this example we are doing an upgrade from 11.2 to 19c. The process is very similar for all supported versions, but the pre-upgrade and post-upgrade fixup actions may vary a little.

It's important to have backups of everything before you start! Some of these steps are destructive, and if something goes wrong you have no alternative but to restore from backups and start again.

◉ Prerequisities

Make sure you have all the OS prerequisites in place by running the 19c preinstall package. On Oracle Linux you can do this by installing the preinstall package. It probably makes sense to update the remaining packages also.

yum install -y oracle-database-preinstall-19c

yum update -y

◉ Install 19c Software

You can read about the installation process in more detail here, but for this example I'll keep it brief. The following commands will perform a silent installation of the 19c software.

export ORACLE_HOME=$ORACLE_BASE/product/19.0.0/dbhome_1

export SOFTWARE_DIR=/u01/software

export ORA_INVENTORY=/u01/app/oraInventory

mkdir -p ${ORACLE_HOME}

cd $ORACLE_HOME

/bin/unzip -oq ${SOFTWARE_DIR}/LINUX.X64_193000_db_home.zip

./runInstaller -ignorePrereq -waitforcompletion -silent                        \

    -responseFile ${ORACLE_HOME}/install/response/db_install.rsp               \

    oracle.install.option=INSTALL_DB_SWONLY                                    \

    ORACLE_HOSTNAME=${ORACLE_HOSTNAME}                                         \

    UNIX_GROUP_NAME=oinstall                                                   \

    INVENTORY_LOCATION=${ORA_INVENTORY}                                        \

    SELECTED_LANGUAGES=en,en_GB                                                \

    ORACLE_HOME=${ORACLE_HOME}                                                 \

    ORACLE_BASE=${ORACLE_BASE}                                                 \

    oracle.install.db.InstallEdition=EE                                        \

    oracle.install.db.OSDBA_GROUP=dba                                          \

    oracle.install.db.OSBACKUPDBA_GROUP=dba                                    \

    oracle.install.db.OSDGDBA_GROUP=dba                                        \

    oracle.install.db.OSKMDBA_GROUP=dba                                        \

    oracle.install.db.OSRACDBA_GROUP=dba                                       \

    SECURITY_UPDATES_VIA_MYORACLESUPPORT=false                                 \

    DECLINE_SECURITY_UPDATES=true

Run the root scripts when prompted.

As a root user, execute the following script(s):

        1. /u01/app/oracle/product/19.0.0/dbhome_1/root.sh

At this point you should also patch the new Oracle home, but in this case we will forgo that step to keep things simple.

◉ Run preupgrade.jar

Download the latest "preupgrade.jar" file from MOS 884522.1. If you don't have MOS access you can miss out the next step.

At the time of writing, the latest preupgrade.jar is the one shipped with 19c, so there is no need to download a newer one. I's worth checking to see if this situation has changed when you do your upgrade.

Put the latest "preupgrade.jar" into the 19c Oracle home.

export ORACLE_HOME=$ORACLE_BASE/product/19.0.0/dbhome_1

cd $ORACLE_HOME/rdbms/admin

unzip -o /u01/software/preupgrade_19_cbuild_??_lf.zip

Make sure you are using the original Oracle home and run the "preupgrade.jar".

export ORACLE_SID=db11g

export ORAENV_ASK=NO

. oraenv

export ORAENV_ASK=YES

export ORACLE_HOME=$ORACLE_BASE/product/11.2.0.4/db_1

$ORACLE_BASE/product/19.0.0/dbhome_1/jdk/bin/java -jar $ORACLE_BASE/product/19.0.0/dbhome_1/rdbms/admin/preupgrade.jar TERMINAL TEXT

Here is the output from an example run against an 11.2 database.

$ $ORACLE_BASE/product/19.0.0/dbhome_1/jdk/bin/java -jar $ORACLE_BASE/product/19.0.0/dbhome_1/rdbms/admin/preupgrade.jar TERMINAL TEXT

BEFORE UPGRADE

==============

  REQUIRED ACTIONS

  ================

  None

  RECOMMENDED ACTIONS

  ===================

  1.  Update NUMERIC INITIALIZATION PARAMETERS to meet estimated minimums.

      This action may be done now or when starting the database in upgrade mode

      using the 19 ORACLE HOME.

       Parameter                                 Currently  19 minimum

       ---------                                 ---------  ------------------

       processes                                       150                 300

      The database upgrade process requires certain initialization parameters

      to meet minimum values.  The Oracle upgrade process itself has minimum

      values which may be higher and are marked with an asterisk.  After

      upgrading, those asterisked parameter values may be reset if needed.

  2.  Remove the EM repository.

      - Copy the $ORACLE_HOME/rdbms/admin/emremove.sql script from the target

      19 ORACLE_HOME into the source 11.2.0.4.0 ORACLE_HOME.

      Step 1: If database control is configured, stop EM Database Control,

      using the following command

        $> emctl stop dbconsole

      Step 2: Connect to the database using the SYS account AS SYSDBA

        SET ECHO ON;

        SET SERVEROUTPUT ON;

        @emremove.sql

      Without the set echo and serveroutput commands, you will not be able to

      follow the progress of the script.

      The database has an Enterprise Manager Database Control repository.

      Starting with Oracle Database 12c, the local Enterprise Manager Database

      Control does not exist anymore. The repository will be removed from your

      database during the upgrade.  This step can be manually performed before

      the upgrade to reduce downtime.

  3.  Remove OLAP Catalog by running the 11.2.0.4.0 SQL script

      $ORACLE_HOME/olap/admin/catnoamd.sql script.

      The OLAP Catalog component, AMD, exists in the database.

      Starting with Oracle Database 12c, the OLAP Catalog (OLAP AMD) is

      desupported and will be automatically marked as OPTION OFF during the

      database upgrade if present. Oracle recommends removing OLAP Catalog

      (OLAP AMD) before database upgrade.  This step can be manually performed

      before the upgrade to reduce downtime.

  4.  Upgrade Oracle Application Express (APEX) manually before the database

      upgrade.

      The database contains APEX version 3.2.1.00.12. Upgrade APEX to at least

      version 18.2.0.00.12.

      Starting with Oracle Database Release 18, APEX is not upgraded

      automatically as part of the database upgrade. Refer to My Oracle Support

      Note 1088970.1 for information about APEX installation and upgrades.

  5.  (AUTOFIXUP) Gather stale data dictionary statistics prior to database

      upgrade in off-peak time using:

        EXECUTE DBMS_STATS.GATHER_DICTIONARY_STATS;

      Dictionary statistics do not exist or are stale (not up-to-date).

      Dictionary statistics help the Oracle optimizer find efficient SQL

      execution plans and are essential for proper upgrade timing. Oracle

      recommends gathering dictionary statistics in the last 24 hours before

      database upgrade.

      For information on managing optimizer statistics, refer to the 11.2.0.4

      Oracle Database Performance Tuning Guide.

  6.  (AUTOFIXUP) Directly grant ADMINISTER DATABASE TRIGGER privilege to the

      owner of the trigger or drop and re-create the trigger with a user that

      was granted directly with such. You can list those triggers using: SELECT

      OWNER, TRIGGER_NAME FROM DBA_TRIGGERS WHERE

      TRIM(BASE_OBJECT_TYPE)='DATABASE' AND OWNER NOT IN (SELECT GRANTEE FROM

      DBA_SYS_PRIVS WHERE PRIVILEGE='ADMINISTER DATABASE TRIGGER').

      There is one or more database triggers whose owner does not have the

      right privilege on the database.

      The creation of database triggers must be done by users granted with

      ADMINISTER DATABASE TRIGGER privilege. Privilege must have been granted

      directly.

  7.  (AUTOFIXUP) Gather statistics on fixed objects prior the upgrade.

      None of the fixed object tables have had stats collected.

      Gathering statistics on fixed objects, if none have been gathered yet, is

      recommended prior to upgrading.

      For information on managing optimizer statistics, refer to the 11.2.0.4

      Oracle Database Performance Tuning Guide.

  INFORMATION ONLY

  ================

  8.  To help you keep track of your tablespace allocations, the following

      AUTOEXTEND tablespaces are expected to successfully EXTEND during the

      upgrade process.

                                                 Min Size

      Tablespace                        Size     For Upgrade

      ----------                     ----------  -----------

      SYSAUX                             490 MB       738 MB

      SYSTEM                             740 MB      1175 MB

      TEMP                                29 MB       150 MB

      UNDOTBS1                            70 MB       446 MB

      Minimum tablespace sizes for upgrade are estimates.

  9.  Run $ORACLE_HOME/rdbms/admin/catnoexf.sql located in the new Oracle

      Database Oracle home to remove both EXF and RUL.

      Expression Filter (EXF) or Rules Manager (RUL) exist in the database.

      Starting with Oracle Database release 12.1, the Expression Filter (EXF)

      and Database Rules Manager (RUL) features are desupported, and are

      removed during the upgrade process.  This step can be manually performed

      before the upgrade to reduce downtime.

  10. Check the Oracle Backup and Recovery User's Guide for information on how

      to manage an RMAN recovery catalog schema.

      If you are using a version of the recovery catalog schema that is older

      than that required by the RMAN client version, then you must upgrade the

      catalog schema.

      It is good practice to have the catalog schema the same or higher version

      than the RMAN client version you are using.

  ORACLE GENERATED FIXUP SCRIPT

  =============================

  All of the issues in database DB11G

  which are identified above as BEFORE UPGRADE "(AUTOFIXUP)" can be resolved by

  executing the following

    SQL>@/u01/app/oracle/cfgtoollogs/db11g/preupgrade/preupgrade_fixups.sql

=============

AFTER UPGRADE

=============

  REQUIRED ACTIONS

  ================

  None

  RECOMMENDED ACTIONS

  ===================

  11. Upgrade the database time zone file using the DBMS_DST package.

      The database is using time zone file version 14 and the target 19 release

      ships with time zone file version 32.

      Oracle recommends upgrading to the desired (latest) version of the time

      zone file.  For more information, refer to "Upgrading the Time Zone File

      and Timestamp with Time Zone Data" in the 19 Oracle Database

      Globalization Support Guide.

  12. To identify directory objects with symbolic links in the path name, run

      $ORACLE_HOME/rdbms/admin/utldirsymlink.sql AS SYSDBA after upgrade.

      Recreate any directory objects listed, using path names that contain no

      symbolic links.

      Some directory object path names may currently contain symbolic links.

      Starting in Release 18c, symbolic links are not allowed in directory

      object path names used with BFILE data types, the UTL_FILE package, or

      external tables.

  13. (AUTOFIXUP) Gather dictionary statistics after the upgrade using the

      command:

        EXECUTE DBMS_STATS.GATHER_DICTIONARY_STATS;

      Oracle recommends gathering dictionary statistics after upgrade.

      Dictionary statistics provide essential information to the Oracle

      optimizer to help it find efficient SQL execution plans. After a database

      upgrade, statistics need to be re-gathered as there can now be tables

      that have significantly changed during the upgrade or new tables that do

      not have statistics gathered yet.

  14. Gather statistics on fixed objects after the upgrade and when there is a

      representative workload on the system using the command:

        EXECUTE DBMS_STATS.GATHER_FIXED_OBJECTS_STATS;

      This recommendation is given for all preupgrade runs.

      Fixed object statistics provide essential information to the Oracle

      optimizer to help it find efficient SQL execution plans.  Those

      statistics are specific to the Oracle Database release that generates

      them, and can be stale upon database upgrade.

      For information on managing optimizer statistics, refer to the 11.2.0.4

      Oracle Database Performance Tuning Guide.

  INFORMATION ONLY

  ================

  15. Check the Oracle documentation for the identified components for their

      specific upgrade procedure.

      The database upgrade script will not upgrade the following Oracle

      components:  OLAP Catalog,OWB

      The Oracle database upgrade script upgrades most, but not all Oracle

      Database components that may be installed.  Some components that are not

      upgraded may have their own upgrade scripts, or they may be deprecated or

      obsolete.

  ORACLE GENERATED FIXUP SCRIPT

  =============================

  All of the issues in database DB11G

  which are identified above as AFTER UPGRADE "(AUTOFIXUP)" can be resolved by

  executing the following

    SQL>@/u01/app/oracle/cfgtoollogs/db11g/preupgrade/postupgrade_fixups.sql

◉ Perform Pre-Upgrade Actions

The output from the "preupgrade.jar" lists a number of pre-upgrade recommendations. Some must be manually applied. Others are incorporated into the "preupgrade_fixups.sql" script. In the following example we run all the manual operations as well as the "preupgrade_fixups.sql" script.

# 1) Increase the processes parameter.

sqlplus / as sysdba <<EOF

alter system set processes=300 scope=spfile;

shutdown immediate;

startup;

exit;

EOF

# 2) Remove EM DB Console config.

cp $ORACLE_BASE/product/19.0.0/dbhome_1/rdbms/admin/emremove.sql $ORACLE_HOME/rdbms/admin/emremove.sql

sqlplus / as sysdba <<EOF

SET ECHO ON;

SET SERVEROUTPUT ON;

@$ORACLE_HOME/rdbms/admin/emremove.sql

exit;

EOF

# 3) Remove OLAP catalog.

sqlplus / as sysdba <<EOF

@$ORACLE_HOME/olap/admin/catnoamd.sql

exit;

EOF

# 4) Ignoring the APEX upgrade. This is a junk test instance. Normally APEX would be at latest version.

# 5) Included in AUTOFIXUP.

# 6) This will be unnecessary after removal of EM repository above.

# 7) Included in AUTOFIXUP.

# Recompile invalid objects.

sqlplus / as sysdba <<EOF

@$ORACLE_HOME/rdbms/admin/utlrp.sql

SET SERVEROUTPUT ON;

EXECUTE DBMS_PREUP.INVALID_OBJECTS;

exit;

EOF

# Run preupgrade-fixups.sql script.

sqlplus / as sysdba <<EOF

@/u01/app/oracle/cfgtoollogs/db11g/preupgrade/preupgrade_fixups.sql

exit;

EOF

◉ Upgrade the Database

With the pre-upgrade actions complete we can start the upgrade. Shutdown the source database.

sqlplus / as sysdba <<EOF

shutdown immediate;

exit;

EOF

Copy the config files from the old to the new Oracle home. You should check the contents of the "listener.ora" file to see if there are any references to the Oracle home path. If there are, amend them.

cp $ORACLE_HOME/network/admin/*.ora $ORACLE_BASE/product/19.0.0/dbhome_1/network/admin

# Add this to $ORACLE_BASE/product/19.0.0/dbhome_1/network/admin/sqlnet.ora

# Need to correct password versions and remove this.

cat >> $ORACLE_BASE/product/19.0.0/dbhome_1/network/admin/sqlnet.ora <<EOF

# This should be temporary while you deal with old passwords.

SQLNET.ALLOWED_LOGON_VERSION_SERVER=11

EOF

cp $ORACLE_HOME/dbs/orapwdb11g $ORACLE_BASE/product/19.0.0/dbhome_1/dbs/

cp $ORACLE_HOME/dbs/spfiledb11g.ora $ORACLE_BASE/product/19.0.0/dbhome_1/dbs/

Switch to the 19c listener.

lsnrctl stop

export ORACLE_HOME=$ORACLE_BASE/product/19.0.0/dbhome_1

export PATH=${ORACLE_HOME}/bin:$PATH

lsnrctl start

Start the database using the 19c Oracle home, ready for the upgrade.

sqlplus / as sysdba <<EOF

startup upgrade;

exit;

EOF

You can run the upgrade using either of the following commands. The second is actually just a shorthand for the former.

# Regular upgrade command.

cd $ORACLE_HOME/rdbms/admin

$ORACLE_HOME/perl/bin/perl catctl.pl catupgrd.sql

# Shorthand command.

$ORACLE_HOME/bin/dbupgrade

Here is the output from an example run against an 11.2 database.

The database is shutdown at the end of the upgrade process, so you need to start it before moving on to the post-upgrade actions.

sqlplus / as sysdba <<EOF

startup

exit;

EOF

◉ Perform Post-Upgrade Actions

The output from the "preupgrade.jar" lists a number of post-upgrade recommendations. Some must be manually applied. Others are incorporated into the "postupgrade_fixups.sql" script. In the following example we run all the manual operations as well as the "postupgrade_fixups.sql" script.

# 11) Time zone file.

sqlplus / as sysdba <<EOF

-- Check current settings.

SELECT * FROM v$timezone_file;

SHUTDOWN IMMEDIATE;

STARTUP UPGRADE;

-- Begin upgrade to the latest version.

SET SERVEROUTPUT ON

DECLARE

  l_tz_version PLS_INTEGER;

BEGIN

  l_tz_version := DBMS_DST.get_latest_timezone_version;

  DBMS_OUTPUT.put_line('l_tz_version=' || l_tz_version);

  DBMS_DST.begin_upgrade(l_tz_version);

END;

/

SHUTDOWN IMMEDIATE;

STARTUP;

-- Do the upgrade.

SET SERVEROUTPUT ON

DECLARE

  l_failures   PLS_INTEGER;

BEGIN

  DBMS_DST.upgrade_database(l_failures);

  DBMS_OUTPUT.put_line('DBMS_DST.upgrade_database : l_failures=' || l_failures);

  DBMS_DST.end_upgrade(l_failures);

  DBMS_OUTPUT.put_line('DBMS_DST.end_upgrade : l_failures=' || l_failures);

END;

/

-- Check new settings.

SELECT * FROM v$timezone_file;

COLUMN property_name FORMAT A30

COLUMN property_value FORMAT A20

SELECT property_name, property_value

FROM   database_properties

WHERE  property_name LIKE 'DST_%'

ORDER BY property_name;

exit;

EOF

# 12) Ignored

# 13) AUTOFIXUP

# 14) Gather fixed object stats.

sqlplus / as sysdba <<EOF

EXECUTE DBMS_STATS.GATHER_FIXED_OBJECTS_STATS;

exit;

# AUTOFIXUP

sqlplus / as sysdba <<EOF

exit;

Assuming you didn't hit any problems along the way, your database is upgraded and ready to go now. The following steps are only necessary if you want to convert the non-CDB instance to a pluggable database (PDB).

◉ Create New Container Database (CDB)

There are a number of considerations when creating a container database, but for this example we will keep it simple. The command below creates a new container database (CDB) with no user-defined pluggable databases (PDBs).

# Create new instance.

export SYS_PASSWORD=SysPassword1

export ORACLE_SID=cdb1

dbca -silent -createDatabase                                                    \

     -templateName General_Purpose.dbc                                          \

     -gdbname ${ORACLE_SID} -sid ${ORACLE_SID} -responseFile NO_VALUE           \

     -characterSet AL32UTF8                                                     \

     -sysPassword ${SYS_PASSWORD}                                               \

     -systemPassword ${SYS_PASSWORD}                                            \

     -createAsContainerDatabase true                                            \

     -numberOfPDBs 0                                                            \

     -databaseType MULTIPURPOSE                                                 \

     -memoryMgmtType auto_sga                                                   \

     -totalMemory 2000                                                          \

     -storageType FS                                                            \

     -datafileDestination "/u02/oradata/"                                       \

     -redoLogFileSize 500                                                       \

     -emConfiguration NONE                                                      \

     -ignorePreReqs

For a proper conversion we would have to make sure the CDB had all necessary configuration in place, including options and initialisation parameters. We will ignore the rest of the instance setup to keep it simple.

◉ Convert Non-CDB to PDB

Oracle Database 19c, Oracle Database Exam Prep, Oracle Database Preparation
Describe the non-CDB instance and turn it off.

export ORACLE_SID=db11g

sqlplus / as sysdba <<EOF

SHUTDOWN IMMEDIATE;

STARTUP OPEN READ ONLY;

BEGIN

  DBMS_PDB.DESCRIBE(

    pdb_descr_file => '/u01/software/db11g.xml');

END;

/

SHUTDOWN IMMEDIATE;

exit;

EOF

Create a PDB using description of the non-CDB, moving the datafiles into the new location, remembering to run the "noncdb_to_pdb.sql" to clean up before opening the pluggable database.

export ORACLE_SID=cdb1

mkdir -p /u02/oradata/CDB1/pdb1/

sqlplus / as sysdba <<EOF

CREATE PLUGGABLE DATABASE pdb1 USING '/u01/software/db11g.xml'

  MOVE

  FILE_NAME_CONVERT = ('/u02/oradata/db11g/', '/u02/oradata/CDB1/pdb1/');

ALTER SESSION SET CONTAINER=pdb1;

@$ORACLE_HOME/rdbms/admin/noncdb_to_pdb.sql

ALTER PLUGGABLE DATABASE OPEN;

ALTER PLUGGABLE DATABASE SAVE STATE;

exit;

EOF

◉ Final Steps

We need to clean up the remains of the non-CDB instance. We can use the DBCA to do this.

dbca -silent -deleteDatabase -sourceDB db11g -sysDBAUserName sys -sysDBAPassword ${SYS_PASSWORD}

We can delete any remaining files.

rm /u01/app/oracle/product/11.2.0.4/db_1/dbs/*db11g*

rm /u01/app/oracle/product/19.0.0/dbhome_1/dbs/*db11g*

rm -Rf $ORACLE_BASE/admin/db11g

rm -Rf /u01/app/oracle/diag/rdbms/db11g

rm -Rf /u02/oradata/db11g

Edit the "/etc/oratab" file as required.
