Upgrade oracle 12c to 19C

A system perform well, but we have to update it then and now due to this evolving era

Why upgrade to 19c

Long term release <-> Premier support <-> end of support coming soon for old versions

current DB version : 12.1.0.2.0 (single instance non PDB)

upgraded DB version : 19.0.0.0.0

12C oracle home : /apps01/product/12.1.0/dbhome

19C oracle home : /data01/product/19.0.0

Database name : orcl19x1

Direct upgrade paths recommendation :

Other database versions apart from below doesnot support direct upgrade

for example (12.1.0.1) has to be upgraded to 19c ,once it is upgraded to the below intermediate versions

From the above paths,we have 12.1.0.2 version which can be directly upgraded to 19c

Download the 19c software from the link and stage the file in oracle home directory

https://www.oracle.com/downloads/software-license-agreement.html#license-lightbox

PREREQUISITES:

Unzip the 19c file:

[root@orcl19x 19.0.0]# unzip LINUX.X64_193000_db_home

Install the 19C software on the host

Take a tar ball of 12c oracle home

[root@orcl19x 12.1.0]# tar -cvf dbhome12c.tar /apps01/ >/dev/null 2>&1
[root@orcl19x 12.1.0]#
[root@orcl19x 12.1.0]# ls
dbhome_1  dbhome12c.tar

Notify application team to refrain access the database

Start the database in restricted mode to stop incoming connections to the database

Take consistent cold backup if downtime can be afford or take hot incremental backup of database (the database should be in archivelog mode for hot backup)

Create a new directory for 19c and give permissions to 19c oracle home

[root@orcl19x product]# mkdir 19.0.0
[root@orcl19x product]# pwd

Check for invalid objects on database.If there are invalid objects then recompile objects with UTLRP or UTL_RECOMP.recomp_parallel(4)

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

If you find invalid objects,then recompile the objects

Create a temporary directory to store the upgrade scripts

[oracle@orcl19x admin]$ mkdir /tmp/preupgrade
[oracle@orcl19x admin]$ echo $ORACLE_SID

[oracle@orcl19x admin]$ echo $ORACLE_HOME
/apps01/product/12.1.0/dbhome_1

Invoke the preupgrade.jar script in 19c OH from 12c java package to generate the pre and post upgrade scripts

[oracle@orcl19x admin]$ /apps01/product/12.1.0/dbhome_1/jdk/bin/java -jar /apps0                                                                                                             1/product/19.0.0/dbhome/rdbms/admin/preupgrade.jar FILE DIR /tmp/preupgrade

==================
  /tmp/preupgrade/preupgrade.log
  /tmp/preupgrade/preupgrade_fixups.sql
  /tmp/preupgrade/postupgrade_fixups.sql

Execute fixup scripts as indicated below:

Before upgrade:

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

After the upgrade:

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

Preupgrade complete: 2020-11-24T18:39:58

Check the preupgrade.log file and follow the steps

Note: If there are errors in any step,dont skip the errors until you resolve them.Otherwise you might get into trouble in the middle of the upgrade process and waste time

Keep track of the tablespace size because after upgrade they increase in size

                                                 Min Size
      Tablespace                        Size     For Upgrade

It is good practice to have the catalog schema the same or higher version than the RMAN client version you are using.After upgrade ,catalog also should be upgraded

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.

Determine the Installation Type

Check the count for schema APEX with the version on wwv_flows table

If the query returns 0, it is a runtime only installation, and apxrtins.sql should be used for the upgrade.

If the query returns 1, this is a development install and apexins.sql should be used.

APEX component should be manually upgraded,so it can be done before database upgrade to save downtime

Check for the materialized views in the database currently

Refresh the materialized views which are there on the database

Please make sure that all the MVs are refreshed and sys.sumdelta$ becomes
      empty before doing upgrade, unless you have strong business reasons not
      to do so. You can use dbms_mview.refresh() to refresh the MVs except
      those stale ones  to be kept due to business need. If there are any stale
      MVs depending on changes in sys.sumdelta$, do not truncate it, because
      doing so will cause wrong results after refresh.

Before upgrade,the sumdelta sys view should be empty

Gather stale data dictionary statistics prior to database upgrade in off-peak time.This will boost SQL execution performance

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.

Check for triggers which doesnot have ‘ADMINISTER DATABASE PRIVILEGE‘.

If not grant the right privileges.In my case,all triggers has correct privileges in place

Find the tablespaces for which autoextend is enabled

Tablespace grow after upgrade.Keep monitor them and check the estimates

Purge the recyclebin table

After the fixup,verify the actions column again if we need to take any action

We can ignore optional messages

Check the FRA and archive log destinations on the server for available space

Database should be in archivelog mode

Stop the listener

Enable guaranteed flashback on database for safer side in case of failure,we can rollback the database to previous state

Create a restore point with GF

Verify the restore point

Compatible parameter should be same as database version

START UPGRADE ACTIVITY

Verify if pfile,spfile,password file and network files are there in place in 19c dbs location

export the env variables like oracle sid and home

Connect to 19c home sqlplus and start the instance in upgrade mode

Verify the version and status of instance.Note that from this step onwards, i have renamed the database name from orcl19x to orcl19x1

Call the catctl and catupgrd scripts from 19c home and based on the CPU cores ,give the degree of parallelism for faster upgrade process or use dbupgrade script

Monitor the CPU consumption for peak utilization on the host using TOP during the upgrade process

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.

Test the application connectivity and behaviour with 19c oracle for any performance issues but obviously 19c has more performance benefits !

Delete the flashback logs from mountpoint to clear unwanted flashback logfile generated from guarantee flashback after application connections are validated

Just decrease the flashback retention target to delete files automatically

Here i given 1 sec to instantly delete the log files to clear space
