By Mouhamadou Diaw<\/strong><\/p>\n

Oracle 12.2 is released and we will have to upgrade. And in this blog we are going to talk about upgrading to oracle 12.2 using the dbupgrade utility.<\/p>\n

Of course the dbua tool is still available and can be also used.<\/p>\n

Oracle Database 12.1 introduced the Parallel Upgrade Utility, catctl.pl. This utility reduces the total amount of time it takes to perform an upgrade by loading the database dictionary in parallel, and by using multiple SQL processes to upgrade the database.<\/p>\n

In Oracle 12.1 catcpl.pl had to be run using perl like
\n$ORACLE_HOME\/perl\/bin\/perl catctl.pl -n 8 -l \/home\/oracle catupgrd.log<\/code>
\nStarting with Oracle 12.2, we can use dbupgrade utility which starts up catctl.pl instead to run it from perl.<\/p>\n

In this article we will describe the steps for upgrade using dbupgrade<\/span>.<\/p>\n

The first step is to run the preupgrade information tool preupgrade.jar<\/span> tool which replaced the preupgrd.sql and utluppkg.sql scripts. This tool can be run from operating system command line. Remember that in 12.1, the Pre-Upgrade Information Tool was run within SQL*Plus as a SQL file.<\/p>\n

Following environment variables must be set. Indeed ORACLE_HOME must point to the earlier release.
\n
\n[oracle@serveroracle ~]$ export ORACLE_HOME=\/u01\/app\/oracle\/product\/12.1.0\/dbhome_1
\n[oracle@serveroracle ~]$ export ORACLE_BASE=\/u01\/app\/oracle
\n[oracle@serveroracle ~]$ export ORACLE_SID=ORCL
\n[oracle@serveroracle ~]$ export PATH=.:$ORACLE_HOME\/bin:$PATH
\n<\/code>
\nThe preupgrade.jar file is located to the oracle 12.2 $ORACLE_HOME\/rdbms\/admin. We can execute it using the TERMINAL or FILE options. The TERMINAL option will send output in the terminal and with FILE we will have the output in a file.
\n
\noracle@serveroracle:~[ORCL] $ORACLE_HOME\/jdk\/bin\/java -jar \/u01\/app\/oracle\/product\/12.2.0.1\/dbhome_1\/rdbms\/admin\/preupgrade.jar TERMINAL TEXT

\noracle@serveroracle:~[ORCL]
\n<\/code>
\nAs specified if we want the output in a file, we can use the option FILE instead of TERMINAL. The output directory is $ORACLE_BASE\/cfgtoollogs\/$ORACLE_SID
\n
\n[oracle@serveroracle ~]$ $ORACLE_HOME\/jdk\/bin\/java -jar \/u01\/app\/oracle\/product\/12.2.0.1\/dbhome_1\/rdbms\/admin\/preupgrade.jar FILE TEXT

\n\/u01\/app\/oracle\/cfgtoollogs\/ORCL\/preupgrade\/postupgrade_fixups.sql
\n[oracle@serveroracle ~]$
\n<\/code>
\nOnce the execution done, the tool will identify possible issues during the upgrade and will also generate 2 scripts
\n\uf0d8 preupgrade_fixups.sql: fixes issues that an automated script can fix safely. This script must be run before the upgrade
\n\uf0d8 postupgrade_fixups.sql: fixes the upgrade issues that can be automatically fixed after the upgrade.
\nFor all other issues we have to manually fix them.
