19c Combo OJVM-DB-RU

TOC

Overview

The following covers applying the OJVM-DB Release Update (RU) combo patch to a standard database. Patch 37591483 is used in these examples (AKA April 2025).

Combo Patch Fun Facts!

opatch

  • opatch updates the Oracle binaries.
  • You must shutdown all databases and listener before running opatch.

datapatch

  • datapatch loads modified SQL files into the database.
  • datapatch must be run for each separate database being patched.
    Set the ORACLE_SID for each before running.

Data Guard (DG) Environment

  • Patch DG systems first.
  • Patch binaries (opatch) on both primary and standby.
  • For SQL Patching (datapatch), only run on the primary.

Misc

  • Perform above logged in as the oracle user.
  • Combo Patch includes both Database RU and the OJVM RU.
  • RU = Release Update.
  • An RU changes the minor version.
    For example: 19.nn to 19.27.

Prerequisites

  • If using VMware or VirtualBox, take a snapshot before beginning.
  • Ensure you have the latest OPatch.
  • Confirm the Oracle inventory is OK.
    Example: $ORACLE_HOME/OPatch/opatch lsinventory -detail -oh $ORACLE_HOME
  • Download Combo patch (Doc ID 2118136.2):
    1. What would you like to download? OJVM Update/PSU/Bundle Patches
    2. Please select the version: 19.0.0.0
    3. Download: OJVM + DB Update (37591483) 🠊 Select OS (Linux x86-64)
    4. As oracle user copy patch .zip file to your patches dir.
  • Run My Oracle Support's Conflict Checker to detect and resolve any conflicts.
  • Unzip the downloaded combo patch zip file.

Example 

 su - oracle
 mkdir /u04/patches/2025-Apr
 DL to /u04/patches/2025-Apr
 cd /u04/patches/2025-Apr
 cp p37591483_190000_Linux-x86-64.zip /u01/orasw/patches/
 cd /u01/orasw/patches
 unzip p37591483_190000_Linux-x86-64.zip
A sub directory with the matching patch number (37591483) will be created.
  • List included major patch sets.

cd /u01/orasw/patches/37591483
ls -l
37642901 (DB RU)
37499406 (OJVM RU)

• There is a README.html in each top-level sub dir that identifies type (DB or OJVM).
• <title>Oracle Database Patch 37642901 - Database Release Update 19.nnn</title>
• <title>Oracle Database Patch 37499406 - Oracle JavaVM Component Release Update 19.nnn</title>

One of the biggest reasons patches fail is lack of disk space in your ORACLE_HOME. Ensure you have 25gb or more free.

Database RU

Database RU: opatch

 su - oracle

 -- If Data Guard Environment, Stop Managed Recovery
 dgmgrl sys/*********@${ORACLE_SID,,}
 DGMGRL> edit database 'standby_db' set state='apply-off';
 Replace standby_db with your SB name.

 -- Stop Database(s) and Listener
 oracle> export ORACLE_SID=MyOraSid
 oracle> sqlplus / as sysdba
 SQLPLUS> shutdown immediate
 SQLPLUS> exit

 oracle> lsnrctl stop

 -- Prep Env (keep this window open to do OJVM as env already set)
 export PATH=$PATH:/usr/ccs/bin
 export PATH=$PATH:$ORACLE_HOME/OPatch
 cd $ORACLE_HOME/OPatch

 If Linux 8 run: export CV_ASSUME_DISTID=OEL8.1

 All cmds on one line (includes OEL8.1):
 export CV_ASSUME_DISTID=OEL8.1;export PATH=$PATH:/usr/ccs/bin;export PATH=$PATH:$ORACLE_HOME/OPatch;cd $ORACLE_HOME/OPatch

 -- Execute opatch
 ./opatch apply /u01/orasw/patches/37591483/37642901

    Verifying environment and performing prerequisite checks...[5-15 minutes]

    Do you want to proceed? [y|n]: y
    Is the local system ready for patching? [y|n]: y
    Process runs...

    Upon completion the status will be displayed on screen.
    Example: OPatch succeeded.

 -- Start Database(s) and Listener
 oracle> lsnrctl start

 oracle> export ORACLE_SID=MyOraSid
 oracle> sqlplus / as sysdba
 SQLPLUS> startup
          IF Data Guard Database 🠊 startup mount
 SQLPLUS> exit

 -- Update Permissions
 DBRU relinks libraries & executables and can change permissions.
 Execute the following as root user:
 export ORACLE_HOME=/u01/app/oracle/product/19.3.0.0.0/dbhome_1
 chown root $ORACLE_HOME/bin/extjob
 chmod 4750 $ORACLE_HOME/bin/extjob

The chown 4 (setuid) allows file to run with the priv of owner, rather than privs of user running executable.

OJVM RU

OJVM RU: opatch

 -- Shutdown DB and Listener
 sqlplus / as sysdba
 shutdown immediate
 exit

 lsnrctl stop

 -- Run: opatch apply 
 cd $ORACLE_HOME/OPatch
 ./opatch apply /u01/orasw/patches/37591483/37499406 -oh $ORACLE_HOME

    Do you want to proceed? [y|n]: y
    Is the local system ready for patching? [y|n]: y
    Process runs...

    Upon completion the status will be displayed on screen.
    Example: OPatch succeeded.

 -- Startup DB and Listener

 lsnrctl start

OJVM RU: datapatch

OJVM Status Check

Rollback Patch

Patch Deinstallation Instructions for a Non-RAC, Non-CDB Environment.

Rollback Fun Facts

  • Do the OJVM then Database Update.
  • opatch rollback also automactically rolls back the SQL changes (AKA datapatch).

Procedure

 0. Note current patch versions.
    $ORACLE_HOME/OPatch/opatch lspatches 

 0. Prep Env
    export CV_ASSUME_DISTID=OEL8.1;export PATH=$PATH:/usr/ccs/bin;export PATH=$PATH:$ORACLE_HOME/OPatch;cd $ORACLE_HOME/OPatch

 1. Shut down all instances and listeners associated with the Oracle home. 

     If Linux 8 run: export CV_ASSUME_DISTID=OEL8.1

     -- Stop Database(s) and Listener
     oracle> export ORACLE_SID=MyOraSid
     oracle> sqlplus / as sysdba
     SQLPLUS> shutdown immediate
     SQLPLUS> exit

     oracle> lsnrctl stop

 2. Run the OPatch utility specifying the rollback argument as follows:
    opatch rollback -id 37499406 (OJVM)
    opatch rollback -id 37642901 (Database Update)

 3. QC
    $ORACLE_HOME/OPatch/opatch lspatches

 4. After the rollback is complete, you will need to restart the 
    database for the changes to take effect.

    -- Start Database(s) and Listener
    oracle> lsnrctl start

    oracle> export ORACLE_SID=MyOraSid
    oracle> sqlplus / as sysdba
    SQLPLUS> startup
    SQLPLUS> exit
