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/19.0.0.0/grid ============================== ### Create tarball for 19.8 GRID_HOME from RAC instance: [code] [root@ol7-19-lax1 grid]# pwd /u01/app/19.0.0/grid [root@ol7-19-lax1 grid]# time tar -cvzpf /tmp/grid19.8_clone.tar.gz . > /tmp/clone_grid19.8.log ; echo $? [/code] ### Transfer tarball to target. ============================== TARGET: 19c Oracle Restart is located at /u01/app/oracle/19.8.0.0/grid ============================== I know what you are thinking. Why is GRID_HOME at two different locations? The two vagrant boxes I have used to create test cases were created by two different individuals. ### Review current patch for 12.2 Oracle Restart: [code] [grid@db-asm-1 ~]$ $ORACLE_HOME/OPatch/opatch lspatches 27144050;Tomcat Release Update 12.2.0.1.0(ID:171023.0830) (27144050) 26839277;DBWLM RELEASE UPDATE 12.2.0.1.0(ID:170913) (26839277) 28163235;ACFS JUL 2018 RELEASE UPDATE 12.2.0.1.180717 (28163235) 28163190;OCW JUL 2018 RELEASE UPDATE 12.2.0.1.180717 (28163190) 28163133;Database Jul 2018 Release Update : 12.2.0.1.180717 (28163133) OPatch succeeded. [/code] ### Copy tarball to /u01/app/oracle/19.8.0.0. [code] [grid@db-asm-1 19.8.0.0]$ time cp -fv /media/swrepo/grid19.8_clone.tar.gz . ; echo $? ‘/media/swrepo/grid19.8_clone.tar.gz’ -> ‘./grid19.8_clone.tar.gz’ [grid@db-asm-1 19.8.0.0]$ ls -l total 7015760 -rwxr-xr-x 1 grid oinstall 7184131622 Aug 15 22:30 grid19.8_clone.tar.gz [/code] ### Unzip tarball to /u01/app/oracle/19.8.0.0 [code] [grid@db-asm-1 19.8.0.0]$ time gunzip grid19.8_clone.tar.gz [grid@db-asm-1 19.8.0.0]$ ls -l total 13542216 -rwxr-xr-x 1 grid oinstall 13867223040 Aug 15 22:30 grid19.8_clone.tar [/code] ### Create directory for GRID_HOME - /u01/app/oracle/19.8.0.0/grid [code] [grid@db-asm-1 19.8.0.0]$ mkdir grid [/code] ### Untar to GRID_HOME - /u01/app/oracle/19.8.0.0/grid [code] [grid@db-asm-1 19.8.0.0]$ cd grid [grid@db-asm-1 grid]$ time tar xf ../grid19.8_clone.tar . ; echo $? [/code] ### Upgrade 12.2 Oracle HAS to 19.8 using 19.8 tarball (GUI Method): [code] [grid@db-asm-1 grid]$ ./gridSetup.sh [/code] ### Verify Oracle Restart is 19.8: [code] [grid@db-asm-1 grid]$ $ORACLE_HOME/OPatch/opatch lspatches 31335188;TOMCAT RELEASE UPDATE 19.0.0.0.0 (31335188) 31305087;OCW RELEASE UPDATE 19.8.0.0.0 (31305087) 31304218;ACFS RELEASE UPDATE 19.8.0.0.0 (31304218) 31281355;Database Release Update : 19.8.0.0.200714 (31281355) OPatch succeeded. [grid@db-asm-1 grid]$ [/code] 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.
