In previous<\/a> article we saw how to patch an Oracle database. In this article we will see the same process in an environment Oracle Data Guard<\/strong> on a UNIX operating system. The steps we will follow allow us to do the process even online<\/strong> if we make use of it Oracle TAF<\/a>.<\/p>\n\n\n\n

<\/p>\n\n\n\n

How to download the patch set update<\/h2>\n\n\n\n

Through the Oracle support portal, we connect to the following link:<\/p>\n\n\n\n

https://support.oracle.com\/portal\/<\/code><\/pre>\n\n\n\n
We select Patches & Updates and search for the patch id we want. In this case we are looking for patch 33192793 to upgrade from version 19.03 to 19.13:<\/p>\n\n\n\n
\"\"
01<\/figcaption><\/figure>\n\n\n\n
When it is downloaded, copy it to \/oracle\/home and unzip it on both Data Guard servers:<\/p>\n\n\n\n
cd $HOME\nunzip p33192793_190000_Linux-x86-64.zip\n<\/pre>\n\n\n\n
<\/p>\n\n\n\n
How to install the latest OPatch<\/h2>\n\n\n\n
However, in order to apply a latest patch, we must also have updated the Oracle tool that performs this process, which is called OPatch.<\/p>\n\n\n\n
To download the latest version we connect to the link below:<\/p>\n\n\n\n
https://updates.oracle.com\/download\/6880880.html<\/code><\/pre>\n\n\n\n
We choose the correct release and operating system (careful with 32 and 64bit):<\/p>\n\n\n\n
\"\"
02<\/figcaption><\/figure>\n\n\n\n
After we download it, we transfer it to both servers, e.g. in the \/oracle\/home<\/code>, from there we transfer it to $ORACLE_HOME<\/code> of each and unzip it in place of the old OPatch folder:<\/p>\n\n\n\n
\"\"
03<\/figcaption><\/figure>\n\n\n\n
cp p688* $ORACLE_HOME\/\ncd $ORACLE_HOME\nunzip p6880880_121010_LINUX.zip\n<\/pre>\n\n\n\n
When the process is complete, we run the following on both servers to see that the version has passed successfully:<\/p>\n\n\n\n
$ORACLE_HOME\/OPatch\/opatch version<\/pre>\n\n\n\n
\"\"
04<\/figcaption><\/figure>\n\n\n\n
<\/p>\n\n\n\n
The process<\/h2>\n\n\n\n
For a start in the case that we have activated the Fast-Start Failover <\/strong>in Data Guard we disable it:<\/p>\n\n\n\n
dgmgrl \"sys\/Kwdikos1!\"@ORADEV\n\nshow configuration;\n\ndisable fast_start failover\n<\/pre>\n\n\n\n
\"\"
05<\/figcaption><\/figure>\n\n\n\n
Then we connect to Standby <\/strong>and we stop the base which is now mount state and the listener:<\/p>\n\n\n\n
lsnrctl stop\n\nsqlplus \/ as sysdba\nshutdown immediate;\nexit;\n<\/pre>\n\n\n\n
Go to the folder where the patch is located:<\/p>\n\n\n\n
cd $HOME\n\nls -ltr\n\ncd 33192793<\/pre>\n\n\n\n
Now we can start the update process:<\/p>\n\n\n\n
$ORACLE_HOME\/OPatch\/opatch apply<\/pre>\n\n\n\n
Patching component oracle.jdk, 1.8.0.201.0...\nPatch 33192793 successfully applied.\nSub-set patch [29517242] has become inactive due to the application of a super-set patch [33192793].\nPlease refer to Doc ID 2161861.1 for any possible further required actions.\nLog file location: \/oracle\/app\/oracle\/product\/19.3.0\/dbhome_1\/cfgtoollogs\/opatch\/opatch2022-07-06_22-26-07PM_1.log\n\nOPatch succeeded.<\/code><\/pre>\n\n\n\n
With that completed we connect to the database, raise it to mount state and raise the listener:<\/p>\n\n\n\n
sqlplus \/ as sysdba\nstartup mount\nexit;\n\nlsnrctl start<\/pre>\n\n\n\n
As a next step we connect to Primary's Data Guard Broker <\/strong>and after we see that it has synchronized, i.e. that the Configuration Status has turned to success, we switchover to Standby:<\/p>\n\n\n\n
* It may take some time for the status to show success, so we run the show configuration command until it shows no error<\/em><\/p>\n\n\n\n
dgmgrl \"sys\/Kwdikos1!\"@ORADEV\n\nshow configuration verbose;\n\nswitchover to oradevdr;<\/pre>\n\n\n\n
\"\"
06<\/figcaption><\/figure>\n\n\n\n
After returning to Standby, we can now apply the patch to the Primary <\/strong>with the same process as we did before. <\/p>\n\n\n\n
We connect to Primary <\/strong>and we stop the base which is now mount state and the listener:<\/p>\n\n\n\n
lsnrctl stop\n\nsqlplus \/ as sysdba\nshutdown immediate;\nexit;\n<\/pre>\n\n\n\n
Go to the folder where the patch is located:<\/p>\n\n\n\n
cd $HOME\n\nls -ltr\n\ncd 33192793<\/pre>\n\n\n\n
Now we can start the update process on the old Primary as well:<\/p>\n\n\n\n
$ORACLE_HOME\/OPatch\/opatch apply<\/pre>\n\n\n\n
Patch 33192793 successfully applied.\nSub-set patch [29517242] has become inactive due to the application of a super-set patch [33192793].\nPlease refer to Doc ID 2161861.1 for any possible further required actions.\nLog file location: \/oracle\/app\/oracle\/product\/19.3.0\/dbhome_1\/cfgtoollogs\/opatch\/opatch2022-07-06_23-08-03PM_1.log\n\nOPatch succeeded.<\/code><\/pre>\n\n\n\n
With that completed we connect to the database, raise it to mount state and raise the listener:<\/p>\n\n\n\n
sqlplus \/ as sysdba\nstartup mount\nexit;\n\nlsnrctl start<\/pre>\n\n\n\n
Now we connect again to Secondary's Data Guard Broker<\/strong> and after we see that it has synchronized, i.e. that the Configuration Status has turned to success, we switchover to the old Primary:<\/p>\n\n\n\n
* It may take some time for the status to show success, so we run the show configuration command until it shows no error<\/em><\/p>\n\n\n\n
dgmgrl \"sys\/Kwdikos1!\"@ORADEVDR\n\nshow configuration verbose;\n\nswitchover to oradev;<\/pre>\n\n\n\n
If it completes successfully we can activate it again Fast-Start Failover<\/strong>:<\/p>\n\n\n\n
enable fast_start failover;\nexit;<\/pre>\n\n\n\n
<\/p>\n\n\n\n
The patch on the Oracle binaries has been completed, but now it remains to pass the update to the database tables as well<\/h2>\n\n\n\n
To do this we need to run the command datapatch<\/strong>, so we connect to Primary and run the following:<\/p>\n\n\n\n
$ORACLE_HOME\/OPatch\/datapatch -verbose<\/pre>\n\n\n\n
\"\"
07<\/figcaption><\/figure>\n\n\n\n
If it shows us an error, we can see more information about what is causing it by selecting the following view:<\/p>\n\n\n\n
select * from OPATCH_XML_INV;\n\n--https:\/\/support.oracle.com\/epmos\/faces\/DocumentDisplay?_afrLoop=331756942002519&parent=EXTERNAL_SEARCH&sourceId=PROBLEM&id=1602089.1&_afrWindowMode=0&_adf.ctrl-state=l7kdhyc44_4<\/pre>\n\n\n\n
When the process is complete we connect to the database and run the following query to confirm that it has been updated:<\/p>\n\n\n\n
sqlplus \/ as sysdba\n\nselect patch_id,status,action_time,description from dba_registry_sqlpatch order by action_time;<\/pre>\n\n\n\n
\"\"
08<\/figcaption><\/figure>\n\n\n\n
To delete the garbage left from the installation, run it opatch cleanup<\/strong>:<\/p>\n\n\n\n
$ORACLE_HOME\/OPatch\/opatch util cleanup<\/pre>\n\n\n\n
<\/p>\n\n\n\n
If we want to rollback the patch...<\/h2>\n\n\n\n
In the event that we want to rollback the patch, we can, while we have downloaded the database, run the following command stating the patch id that we want to remove:<\/p>\n\n\n\n
$ORACLE_HOME\/OPatch\/opatch rollback -id 31113348<\/pre>\n\n\n\n
However, after the rollback to the Oracle binaries is completed, we should run datapatch again (with the database uploaded) so that the changes to the database tables will also be passed:<\/p>\n\n\n\n
