==============
BEFORE UPGRADE
==============

  Run /preupgrade_fixups.sql to complete all
  of the BEFORE UPGRADE action items below marked with '(AUTOFIXUP)'.

  REQUIRED ACTIONS
  ================
   + Adjust TABLESPACE SIZES as needed.
                                                Auto      12.2.0.1.0
     Tablespace                        Size     Extend    Min Size    Action
     ----------                     ----------  --------  ----------  ------

     SYSAUX                             500 MB  ENABLED      1401 MB  None
     SYSTEM                             750 MB  ENABLED      1253 MB  None
     TEMP                                20 MB  ENABLED       150 MB  None
     UNDOTBS1                            50 MB  ENABLED       400 MB  None

     Note that 12.2.0.1.0 minimum sizes are estimates.
     If you plan to upgrade multiple pluggable databases concurrently,
     then you must ensure that the UNDO tablespace size is equal to at least
     the number of pluggable databases that you upgrade concurrently,
     multiplied by that minimum.  Failing to allocate sufficient space can
     cause the upgrade to fail.




   + Update NUMERIC INITIALIZATION PARAMETERS to meet estimated minimums.

     Parameter                         12.2.0.1.0 minimum
     ---------                         ------------------
     processes                                        300




  RECOMMENDED ACTIONS
  ===================
   + Remove the EM repository.

     - Copy the $ORACLE_HOME/rdbms/admin/emremove.sql script from the target 12.2.0.1.0 ORACLE_HOME into the source 11.2.0.4.0 ORACLE_HOME.

     Step 1: If database control is configured, stop EM Database Control,
     using the following command

       $> emctl stop dbconsole

     Step 2: Connect to the database using the SYS account AS SYSDBA

       SET ECHO ON;
       SET SERVEROUTPUT ON;
      @emremove.sql

     Without the set echo and serveroutput commands, you will not be able to
     follow the progress of the script.

     The database has an Enterprise Manager Database Control repository.

     Starting with Oracle Database 12c, the local Enterprise Manager Database
     Control does not exist anymore. The repository will be removed from your
     database during the upgrade.  This step can be manually performed before
     the upgrade to reduce downtime.

   + Remove OLAP Catalog by running the 11.2.0.4.0 SQL script
     $ORACLE_HOME/olap/admin/catnoamd.sql script.

     The OLAP Catalog component, AMD, exists in the database.

     Starting with Oracle Database 12c, the OLAP Catalog (OLAP AMD) is
     desupported and will be automatically marked as OPTION OFF during the
     database upgrade if present. Oracle recommends removing OLAP Catalog
     (OLAP AMD) before database upgrade.

   + (AUTOFIXUP) Gather stale data dictionary statistics prior to database
     upgrade in off-peak time using:

      EXECUTE DBMS_STATS.GATHER_DICTIONARY_STATS;

     Dictionary statistics do not exist or are stale (not up-to-date).

     Dictionary statistics help the Oracle optimizer find efficient SQL
     execution plans and are essential for proper upgrade timing. Oracle
     recommends gathering dictionary statistics in the last 24 hours before
     database upgrade.

     For information on managing optimizer statistics, refer to the 11.2.0.4
     Oracle Database Performance Tuning Guide.

   + Directly grant ADMINISTER DATABASE TRIGGER privilege to the owner of the
     trigger or drop and re-create the trigger with a user that was granted
     directly with such. You can list those triggers using "SELECT OWNER,
     TRIGGER_NAME FROM DBA_TRIGGERS WHERE BASE_OBJECT_TYPE=''DATABASE'' AND
     OWNER NOT IN (SELECT GRANTEE FROM DBA_SYS_PRIVS WHERE
     PRIVILEGE=''ADMINISTER DATABASE TRIGGER'')"

     There is one or more database triggers whose owner does not have the
     right privilege on the database.

     The creation of database triggers must be done by users granted with
     ADMINISTER DATABASE TRIGGER privilege. Privilege must have been granted
     directly.

  INFORMATION ONLY
  ================
   + Consider upgrading APEX manually, before the database upgrade.

     The database contains APEX version 3.2.1.00.12 and will need to be
     upgraded to at least version 5.0.4.00.12.

     To reduce database upgrade time, you can upgrade APEX manually before
     the database upgrade.  Refer to My Oracle Support Note 1088970.1 for
     information on APEX installation upgrades.

   + Ensure there is additional disk space in LOG_ARCHIVE_DEST_1 for at least
     5315 MB of archived logs.  Check alert log during the upgrade that there
     is no write error to the destination due to lack of disk space.  Execute
     'archive log list' and query v$archive_dest for more
     LOG_ARCHIVE_DEST_ destinations to check.

     Archiving cannot proceed if the archive log destination is full during
     upgrade.

     Archive Log Destination:
      Parameter    :  LOG_ARCHIVE_DEST_1
      Destination  :  /u02/arch/coke

     The database has archiving enabled and LOG_ARCHIVE_DEST_ set.  The
     upgrade process will need free disk space in the archive log
     destination(s) to generate archived logs to.

=============
AFTER UPGRADE
=============

  Run /postupgrade_fixups.sql to complete all
  of the AFTER UPGRADE action items below marked with '(AUTOFIXUP)'.

  REQUIRED ACTIONS
  ================
  None

  RECOMMENDED ACTIONS
  ===================
   + Upgrade the database time zone version using the DBMS_DST package.

     The database is using timezone datafile version 14 and the target
     12.2.0.1.0 database ships with timezone datafile version 26.

     Oracle recommends using the most recent timezone data.  For further
     information, refer to My Oracle Support Note 1585343.1.

   + (AUTOFIXUP) Gather dictionary statistics after the upgrade using the
     command:

       EXECUTE DBMS_STATS.GATHER_DICTIONARY_STATS;

     Oracle recommends gathering dictionary statistics after upgrade.

     Dictionary statistics provide essential information to the Oracle
     optimizer to help it find efficient SQL execution plans. After a
     database upgrade, statistics need to be re-gathered as there can now be
     tables that have significantly changed during the upgrade or new tables
     that do not have statistics gathered yet.

   + Gather statistics on fixed objects two weeks after the upgrade using the
     command:

       EXECUTE DBMS_STATS.GATHER_FIXED_OBJECTS_STATS;

     This recommendation is given for all preupgrade runs.

     Fixed object statistics provide essential information to the Oracle
     optimizer to help it find efficient SQL execution plans.  Those
     statistics are specific to the Oracle Database release that generates
     them, and can be stale upon database upgrade.

  INFORMATION ONLY
  ================
   + Check the Oracle documentation for the identified components for their
     specific upgrade procedure.

     The database upgrade script will not upgrade the following Oracle
     components:  OLAP Catalog,OWB

     The Oracle database upgrade script upgrades most, but not all Oracle
     Database components that may be installed.  Some components that are not
     upgraded may have their own upgrade scripts, or they may be deprecated
     or obsolete.
