How to upgrade ORACLE 11G to 19C

In this article, we are going to learn how to upgrade the oracle 11g to 19c database on the Linux platform step by step.

My Environment for this practice

Upgrade oracle 11g to 19c

Prerequisites:

Before starting the upgrade make sure you have done the below checklist:

  1. Stop the Listener
  2. Take full database backup using RMAN
  3. Purge Recycblebin
  4. Gather Dictionary stats
  5. Install Oracle 19c

Click here to know how to install oracle 19c on the Linux platform.

Let’s performing step by step

Step 1: Stop the Listener

Stop the listener before starting the upgrade, it blocks the user connections from the application.

$lsnrctl stop

Step 2: Take full database backup using RMAN

Before starting the database upgradation you must create a full database backup using RMAN.

$rman target/

RMAN>  run {
 allocate channel ch1 type disk;
 backup incremental level 0 tag 'BEFORE_UPGRADE' database format '/u02/backup/%d_%U';
 backup tag 'CONTROL_FILE' current controlfile format '/u02/backup/%d_%T_%s_%p_CONTROL';
 release channel ch1;
 }

Check database status if it’s running or completed before the upgrade using the below commands.

SQL> SELECT * FROM v$backup WHERE status != 'NOT ACTIVE';

no rows selected

Step 3: Purge Recyclebin

This is not mandatory but it will create a problem during the upgrade so you must purge the recyclebin.

SQL> PURGE DBA_RECYCLEBIN ;

DBA Recyclebin purged.

Step 4: Gather Dictionary Stats

Gather dictionary stats before the upgrade, it’ll make it smooth.

SQL> EXEC DBMS_STATS.GATHER_DICTIONARY_STATS;

Upgrade oracle 11g to 19c steps

Follow the below steps to upgrade oracle 11g to 19c step by step.

Upgrade oracle 11g to 19c

Step 1: Run the preupgrade tool

The preupgrade tool helps us to generate prefix and postfix scripts. Before running the preupgrade tool create a directory where it will create these scripts.

$/u01/app/oracle/product/11.2.0/db_1/jdk/bin/java -jar /u01/app/oracle/product/19.3.0/db_1/rdbms/admin/preupgrade.jar FILE DIR /u01/preupgrade/

Output from the above query:

==================
PREUPGRADE SUMMARY
==================
/u01/preupgrade/preupgrade.log
/u01/preupgrade/preupgrade_fixups.sql
/u01/preupgrade/postupgrade_fixups.sql

Execute fixup scripts as indicated below:

Before upgrade:

Log into the database and execute the preupgrade fixups
@/u01/preupgrade/preupgrade_fixups.sql

After the upgrade:

Log into the database and execute the postupgrade fixups
@/u01/preupgrade/postupgrade_fixups.sql

Preupgrade complete: 2022-04-21T21:11:41

Step 2: Run preupgrade_fixups.sql first

The preupgrade_fixups.sql will check if your database is ready to upgrade or not, if there need any fixups it will show in the output, so first fix the issue then go ahead. In my case everything is perfect.

SQL> @/u01/preupgrade/preupgrade_fixups.sql
Executing Oracle PRE-Upgrade Fixup Script

Auto-Generated by: Oracle Preupgrade Script
Version: 19.0.0.0.0 Build: 1
Generated on: 2022-04-21 21:19:24

For Source Database: OCP19C
Source Database Version: 11.2.0.4.0
For Upgrade to Version: 19.0.0.0.0

Preup Preupgrade
Action Issue Is
Number Preupgrade Check Name Remedied Further DBA Action
------ ------------------------ ---------- --------------------------------
1. parameter_min_val NO Manual fixup recommended.
2. em_present NO Manual fixup recommended.
3. amd_exists NO Manual fixup recommended.
4. apex_manual_upgrade NO Manual fixup recommended.
5. dictionary_stats YES None.
6. trgowner_no_admndbtrg YES None.
7. pre_fixed_objects YES None.
8. tablespaces_info NO Informational only.
Further action is optional.
9. exf_rul_exists NO Informational only.
Further action is optional.
10. rman_recovery_version NO Informational only.
Further action is optional.

The fixup scripts have been run and resolved what they can. However,
there are still issues originally identified by the preupgrade that
have not been remedied and are still present in the database.
Depending on the severity of the specific issue, and the nature of
the issue itself, that could mean that your database is not ready
for upgrade. To resolve the outstanding issues, start by reviewing
the preupgrade_fixups.sql and searching it for the name of
the failed CHECK NAME or Preupgrade Action Number listed above.
There you will find the original corresponding diagnostic message
from the preupgrade which explains in more detail what still needs
to be done.

Step 3: Check the timezone version before upgrade

Before upgrading the database check timezone and keep it in a text file to remember that, it will be changed after the upgrade in 19.3.0.

SQL> SELECT version FROM v$timezone_file;

VERSION
-------
14

OR

SQL> SELECT PROPERTY_NAME, SUBSTR(property_value, 1, 30) value
FROM DATABASE_PROPERTIES
WHERE PROPERTY_NAME LIKE 'DST_%'
ORDER BY PROPERTY_NAME; 

PROPERTY_NAME            VALUE
------------------------ -----
DST_PRIMARY_TT_VERSION   14
DST_SECONDARY_TT_VERSION 0
DST_UPGRADE_STATE        NONE

Start to upgrade oracle database 11.2.0.4 to 19.3.0

Step 4: Shutdown the database

Shutdown the database normally.

$sqlplus / as sysdba

SQL> shu immediate

Step 5: Copy the spfile and password file

Create a copy of the spfile and password file from 11g home to 19c home using the below commands.

$ cp /u01/app/oracle/product/11.2.0/db_1/dbs/spfileOCP.ora /u01/app/oracle/product/19.3.0/db_1/dbs/
$ cp /u01/app/oracle/product/11.2.0/db_1/dbs/orapwOCP /u01/app/oracle/product/19.3.0/db_1/dbs/

Step 6: Start database from 19c Home

Start the database upgrade from oracle 19c home.

$ export ORACLE_SID=OCP
$ export ORACLE_HOME=/u02/app/oracle/product/19.3.0/db_1
$ export PATH=/u02/app/oracle/product/19.3.0/db_1:$PATH
$ sqlplus / as sysdba

Step 10: Check Invalid objects details

After the update, you must check the details of invalid objects using the below query.

SQL> select count(*) from dba_objects where status='INVALID';

COUNT(*)
----------
9465

Step 11: Compile Invalid Objects

After the upgrade there are many objects’ status got invalid, so compile these invalid objects using the UTLRP utility.

SQL> @utlrp.sql

Step 12: Update Compatible parameters

Once the upgradation is completed, we should update the compatible parameters as below.

SQL> show parameter compatible;

NAME              TYPE    VALUE
----------------- -------- ---------
compatible        string  11.2.0.4.0
noncdb_compatible boolean FALSE


SQL> ALTER SYSTEM SET COMPATIBLE = '19.3.0' SCOPE=SPFILE;


System altered.

Step 13: Bounce the database

Take your database restart normally.

SQL> shut immediate
Database closed.
Database dismounted.
ORACLE instance shut down.

SQL> startup
ORACLE instance started.

Total System Global Area 2516580184 bytes
Fixed Size 8660824 bytes
Variable Size 671088640 bytes
Database Buffers 1828716544 bytes

Database mounted.
Database opened.

SQL> show parameter compatible;

NAME              TYPE     VALUE
----------------- -------- ---------

Post upgradation steps

Here are the steps which we need to perform after upgradation.

Step 1: Update the timezone version

Start the database in upgrade mode and update the timezone version using the below commands.

SQL> startup upgrade
ORACLE instance started.

Total System Global Area 1543500136 bytes
Fixed Size 8896872 bytes
Variable Size 1040187392 bytes
Database Buffers 486539264 bytes

Database mounted.
Database opened.

SQL> 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;
/

l_tz_version=32
An upgrade window has been successfully started.

SQL> 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;

Executing Oracle POST-Upgrade Fixup Script

Auto-Generated by: Oracle Preupgrade Script
Version: 19.3.0 Build: 1
Generated on: 2022-04-21 21:12:30

For Source Database: ocp
Source Database Version: 11.2.0.4.0
For Upgrade to Version: 19.3.0

Preup                        Preupgrade
Action                       Issue Is 
Number Preupgrade Check Name Remedied      Further DBA Action
------ ------------------------ ---------- ----------------------------
11. old_time_zones_exist YES None.
12. dir_symlinks YES None.
13. post_dictionary YES None.
14. post_fixed_objects NO Informational only.
Further action is optional.
15. upg_by_std_upgrd NO Informational only.
Further action is optional.

The fixup scripts have been run and resolved what they can. However,
there are still issues originally identified by the preupgrade that
have not been remedied and are still present in the database.
Depending on the severity of the specific issue, and the nature of
the issue itself, that could mean that your database upgrade is not
fully complete. To resolve the outstanding issues, start by reviewing
the postupgrade_fixups.sql and searching it for the name of
the failed CHECK NAME or Preupgrade Action Number listed above.
There you will find the original corresponding diagnostic message
from the preupgrade which explains in more detail what still needs
to be done.

Step 4: Verify the below details after the upgrade

Our Oracle 11g to 19c upgrade is completed, just verify the below details.

Check database timezone.

SQL> SELECT * FROM v$timezone_file;

FILENAME             VERSION    CON_ID
-------------------- ---------- ----------
timezlrg_32.dat      32         0

Check version and open mode

SQL> select name,version,open_mode from v$database,v$instance;

NAME      VERSION      OPEN_MODE
--------- ----------  ----------
OCP    19.3.0       READ WRITE

Finally, we have successfully upgraded the oracle 11.2.0.4 database into 19.3.0 on the Linux platform. If you found this article helpful please write your fillings in the comment box.
