CreateGoldImage Followup – Is CreateGoldImage Required for Cloning Oracle Home?

Posted in: Oracle, Technical Track

On October 31, 2019, I blogged about How To Use CreateGoldImage For Cloning In 19c.

CreateGoldImage seems like a nice new feature; however, it’s also very buggy.

Here are a few bugs:

2641469.1 27432355.8 27432338.8

I received a suggestion to use tar to clone Grid Home; however, I was uncertain if it would work.

Why would Oracle create a new process for CreateGoldImage when traditional tar works?

Out of curiosity, I decided to test this by creating tarball for GRID_HOME from 19.8 RAC.

Use the tarball to upgrade Oracle Restart 12.2 to 19.8

Source: 19c Oracle RAC is located at /u01/app/

### Create tarball for 19.8 GRID_HOME from RAC instance:

[[email protected] grid]# pwd
[[email protected] grid]# time tar -cvzpf /tmp/grid19.8_clone.tar.gz . > /tmp/clone_grid19.8.log ; echo $?

### Transfer tarball to target.

TARGET: 19c Oracle Restart is located at /u01/app/oracle/

I know what you are thinking. Why is GRID_HOME at two different locations?

The two vagrant boxes I have used to create test cases were created by two different individuals.

### Review current patch for 12.2 Oracle Restart:

[[email protected] ~]$ $ORACLE_HOME/OPatch/opatch lspatches
27144050;Tomcat Release Update (27144050)
26839277;DBWLM RELEASE UPDATE (26839277)
28163235;ACFS JUL 2018 RELEASE UPDATE (28163235)
28163190;OCW JUL 2018 RELEASE UPDATE (28163190)
28163133;Database Jul 2018 Release Update : (28163133)
OPatch succeeded.

### Copy tarball to /u01/app/oracle/

[[email protected]]$ time cp -fv /media/swrepo/grid19.8_clone.tar.gz . ; echo $?
‘/media/swrepo/grid19.8_clone.tar.gz’ -> ‘./grid19.8_clone.tar.gz’
[[email protected]]$ ls -l
total 7015760
-rwxr-xr-x 1 grid oinstall 7184131622 Aug 15 22:30 grid19.8_clone.tar.gz

### Unzip tarball to /u01/app/oracle/

[[email protected]]$ time gunzip grid19.8_clone.tar.gz
[[email protected]]$ ls -l
total 13542216
-rwxr-xr-x 1 grid oinstall 13867223040 Aug 15 22:30 grid19.8_clone.tar

### Create directory for GRID_HOME – /u01/app/oracle/

[[email protected]]$ mkdir grid

### Untar to GRID_HOME – /u01/app/oracle/

[[email protected]]$ cd grid
[[email protected] grid]$ time tar xf ../grid19.8_clone.tar . ; echo $?

### Upgrade 12.2 Oracle HAS to 19.8 using 19.8 tarball (GUI Method):

[[email protected] grid]$ ./

### Verify Oracle Restart is 19.8:

[[email protected] grid]$ $ORACLE_HOME/OPatch/opatch lspatches
31335188;TOMCAT RELEASE UPDATE (31335188)
31305087;OCW RELEASE UPDATE (31305087)
31304218;ACFS RELEASE UPDATE (31304218)
31281355;Database Release Update : (31281355)
OPatch succeeded.
[[email protected] grid]$

In conclusion, there is an option to use tarball if CreateGoldImage does not work; thereby avoiding creating a ticket with Oracle support.

Please note: I am unaware whether using tarball is supported — it would be best to check with Oracle support.
