Clone database home (clone.pl) deprecated in Oracle 19c

-
Back to blogging, at last. Well, this time it's about clone.pl.

Background about clone.pl

The easiest way to install a patched and up-to-date Oracle home is to physically copy it from a source server (that is already patched and up-to-date) and use clone.pl on the target server so that the binaries are linked to the target server's OS binaries (like gcc, libstdc++ etc.,), registered with the Oracle Inventory etc.

The alternative to clone.pl is to:

  1. Install Oracle binaries using GUI or command line
  2. Apply the latest patchset (PSU/CPU patches)

As you can see now, clone.pl is really useful in order to cut down time to build a database in a new server.

More about clone.pl here and here (12c), here (18c).

However, in Oracle 19c, Oracle has officially said - "Starting from oracle database 19c ,the clone.pl script is deprecated  and can be removed in a future release. Hence, Oracle recommends that you use the software-only installation option, available in the database installer, instead of clone.pl to clone your database.This document provides instructions on how to clone oracle home using gold image concept ." (2565006.1)

Here I list the simple steps to create a gold image and then cloning the target oracle home using that gold image. Hope it helps.

STEP 1: Create gold image zip file

 

Once the 19c software is installed and patched, use the below command to create the gold image zip file:

 

$ $ORACLE_HOME/runInstaller -silent -createGoldImage -destinationLocation <DESTINATION_DIRECTORY>

Launching Oracle Database Setup Wizard...

 

Successfully Setup Software.

Gold Image location: <DESTINATION_DIRECTORY>/db_home_2020-03-30_07-38-54AM.zip

 

STEP 2: Copy gold image to the target location


$ rsync -aS <DIRECTORY_OF_GOLD_IMAGE_ZIP>/db_home_2020-03-30_07-38-54AM.zip <TARGET_USER>@<TARGET_SERVER>:<TARGET_DIR>

 

STEP 3: Unzip the gold image under $ORACLE_HOME

 

Unzip the gold image under the ORACLE_HOME directory (/oracle/product/19.0.0):

 

$ cd $ORACLE_HOME

$ unzip -d $ORACLE_HOME <DESTINATION_DIRECTORY>/db_home_2020-03-30_07-38-54AM.zip

 

 

STEP 4: Execute runInstaller to clone the target ORACLE_HOME

 

Execute runInstaller command to clone the target ORACLE_HOME. Ensure to use the runInstaller binary directly under $ORACLE_HOME.

 

$ ${ORACLE_HOME}/runInstaller -silent -responseFile <PATH_TO_RESPONSE_FILE>

$ ${ORACLE_HOME}/runInstaller -silent -responseFile install.rsp

 

RESPONSE FILE CONTENTS:

 

$ cat install.rsp

oracle.install.responseFileVersion=<PATH>/rspfmt_dbinstall_response_schema_v19.0.0

oracle.install.option=INSTALL_DB_SWONLY

UNIX_GROUP_NAME=dba

INVENTORY_LOCATION=<ACTUAL_INVENTORY_LOCATION>

ORACLE_HOME=<ACTUAL_ORACLE_HOME_LOCATION>

ORACLE_BASE=<ACTUAL_ORACLE_BASE_LOCATION>

oracle.install.db.InstallEdition=EE

oracle.install.db.OSDBA_GROUP=dba

oracle.install.db.OSOPER_GROUP=dba

oracle.install.db.OSBACKUPDBA_GROUP=dba

java.lang.ExceptionInInitializerError while trying to Access login page

-
Today morning, we (the DBAs) were faced with a strange issue. On Saturday (the 14th of February - (St.) Valentine's day!!), the UNIX boxes hosting our critical test instance went down for scheduled maintenance without any prior information. So, we could not bring down our databases and applications. As soon as the unix box came up, we encountered this issue. Let me briefly describe the environment, the issue, the analysis performed and of course, the solution to this most vexing problem. Environment : Apps Version : 11.5.10.2 with ATG RUP 5 DB Version : 10.2.0.3 Architecture : Two Node instance with database + admin on one tier and web server on another. PS : Another instance (development) exists on the same server with the same configuration, which was working fine. Issue : When trying to access the login page of Oracle Apps, received the below error. Even OAM login page was throwing the same error. Request URI: /OA_HTML/AppsLocalLogin.jsp Exception: java.lang.ExceptionInIniti

Solution to "End Program - WMS Idle"

Though this topic is unrelated any Apps DBA topics, I found it necessary to share the solution so that everyone benifits out of it ! Issue: I used to receive the below error message whenever I tried to shutdown windows XP. A rather vexing problem, no doubt. Cause: This message appears because when windows is trying to shutdown and end all the running processes, the WMS idle process keeps working. Thus an end-program message appears. The two most common reasons for this are: Scout service run by Nero 7 Microsoft Office Communicator 2005 Solution: The fix is simple, disable the Nero 7 scout service if it is enabled. For this, go to Start > All Programs > Nero > Tools > Nero Scout . On this screen , Uncheck Enable the Nero scout. This will fix the issue for most of the users, for the rest of you who are not using Nero are most probably getting this error because of Microsoft Office Communicator 2005. For that you need to either manually exit the communicator 2005 from the s

WGET shell Script for downloading patches

-
What I have to offer this time is a script using which you can download patches using WGET from Meta.....oops, from My Oracle Support, I should say! This script needs (or accepts) the following parameters: 1. Me...oops...MOS Username 2. MOS (I got it right this time!) password 3. Patch file name 4. ARU Number You can get 3 and 4 in the following way: Using MOS: Query for the particular patch, click on the download link, click on WGET Options on the left side bottom corner and then copy the WGET script to clipboard. That script will have both the patch name and the ARU number. Using HTML (supporthtml.oracle.com): Query for the particular patch, click on the patch, then RIGHT CLICK on the patch zip file link and click on copy shortcut in IE (or copy link location in Mozilla Firefox). This link will have both the patch file name and the ARU number. Using the classic patches window: Query for the particular patch, then RIGHT CLICK on the DOWNLOAD button and click on copy shortcut in IE (or
