Practical part: conversion of Oracle Database Standard Edition (SE) to Enterprise Edition (EE)

Preface

quite a lot Oracle The standard version was selected during the initial installation of the database , Compared with the enterprise version, there is less ：RAC、ASM、DataGuard、 Flashback function 、 Partition table and other useful functions ：

SELECT *
  FROM v$option
 WHERE parameter IN ('Oracle Data Guard',
                     'Active Data Guard',
                     'Flashback Table',
                     'Flashback Database',
                     'Online Index Build',
                     'Partitioning');
PARAMETER                       			VALUE
-------------------------------------------------
Partitioning                    			FALSE
Online Index Build              			FALSE
Oracle Data Guard               			FALSE
Flashback Table                 			FALSE
Flashback Database              			FALSE
Active Data Guard               			FALSE 

So how to upgrade the standard version to the enterprise version ？Oracle Provided us with specific plans ：

• How to Convert Database from Standard to Enterprise Edition (till 11gR2)? (Doc ID 117048.1)

Now let me test the upgrade process ！

Environmental preparation

Host name

IP Address

Host version

Oracle edition

Instance name

orcl

10.211.55.100

rhel8.6

19.15 SE2

orcl

Formal conversion

Oracle Create databases using the same SQL.BSQ Script , So the database is almost the same internally , The conversion process is not very complicated .

Backup database

First , For the sake of data security , Make a backup before conversion ：

run {
allocate channel c1 device type disk;
allocate channel c2 device type disk;
backup database include current controlfile format '/backup/backdb_%d_%T_%t_%s_%p';
backup archivelog all format '/backup/arch_%d_%T_%t_%s_%p';
release channel c1;
release channel c2;
}

Make sure the backup is successful ：

select input_type,
       status,
       to_char(start_time,
               'yyyy-mm-dd hh24:mi:ss'),
       to_char(end_time,
               'yyyy-mm-dd hh24:mi:ss'),
       input_bytes_display,
       output_bytes_display,
       time_taken_display,
       COMPRESSION_RATIO
  from v$rman_backup_job_details
 order by 3 desc;

It is better to put the parameter file 、 Password file and monitoring file ：

cp -r $ORACLE_HOME/dbs /soft/
cp -r $ORACLE_HOME/network/admin /soft/

Close the database

Shut down all services related to the database ：

lsnrctl stop
sqlplus / as sysdba<<EOF
shu immediate
exit
EOF

uninstall Oracle SE Software

Uninstallation here is not recommended deinstall, It is recommended to use runInstaller To uninstall ORACLE_HOME：

$ORACLE_HOME/oui/bin/runInstaller -silent -detachHome -invPtrLoc /etc/oraInst.loc ORACLE_HOME=$ORACLE_HOME

Use the above command $ORACLE_HOME All files and directories under are preserved , In fact, there is no such thing as $ORACLE_HOME Delete anything from the file system . It just comes from Oracle Central Inventory The specific $ORACLE_HOME All the information about .

May refer to MOS file ：Behaviour of the Oracle De-install/Deinstall/Uninstall Utility in 11gR2 (Doc ID 1363753.1)

install Oracle EE Software

Because of the old ORACLE_HOME Not deleted , So it is suggested to create a new ORACLE_HOME Catalog ：

##  Create a new  ORACLE_HOME
mkdir -p /u01/app/oracle/product/19.3.0/db1
##  Modify environment variables 
export ORACLE_HOME=/u01/app/oracle/product/19.3.0/db1
##  decompression  DB  Software to new  ORACLE_HOME
unzip -q LINUX.X64_193000_db_home.zip -d $ORACLE_HOME
##  decompression  OPatch  Patch pack 
unzip -q -o p6880880_190000_Linux-x86-64.zip -d $ORACLE_HOME
##  install  RU  Patches and  Oracle EE  Software ( You need to call the graphical interface )
cd $ORACLE_HOME
./runInstaller -applyRU /soft/33806152
##  perform  root.sh
/u01/app/oracle/product/19.3.0/db1/root.sh

thus ,Oracle EE installation is complete .

Start database

Before starting the database , The original... Needs to be $ORACLE_HOME/dbs The parameter file under 、 Copy the password file to the new $ORACLE_HOME Next ：

##  Recover parameter file and password file 
cd /soft/dbs
cp orapworcl $ORACLE_HOME/dbs
cp spfileorcl.ora $ORACLE_HOME/dbs

##  Recover the listening file 
cd /soft/admin
cp listener.ora $ORACLE_HOME/network/admin
cp sqlnet.ora $ORACLE_HOME/network/admin
cp tnsnames.ora $ORACLE_HOME/network/admin

Start monitoring and database ：

lsnrctl start
sqlplus / as sysdba<<EOF
startup
exit
EOF

At this time, query the version and optional functions again :

--  Check the database version 
SQL> select banner_full from v$version;

BANNER_FULL
----------------------------------------------------------------------
Oracle Database 19c Enterprise Edition Release 19.0.0.0.0 - Production
Version 19.15.0.0.0
--  Check the optional functions 
SELECT *
  FROM v$option
 WHERE parameter IN ('Oracle Data Guard',
                     'Active Data Guard',
                     'Flashback Table',
                     'Flashback Database',
                     'Online Index Build',
                     'Automatic Storage Management',
                     'Partitioning',
                     'Real Application Clusters');
PARAMETER                       			VALUE
-------------------------------------------------
Partitioning                    			TRUE
Online Index Build              			TRUE
Oracle Data Guard               			TRUE
Flashback Table                 			TRUE
Flashback Database              			TRUE
Active Data Guard               			TRUE 

At this time, the conversion has been successful .

Execute the upgrade script

function catalog.sql and catproc.sql Script ：

sqlplus / as sysdba @?/rdbms/admin/catalog.sql
sqlplus / as sysdba @?/rdbms/admin/catproc.sql

The execution of these two scripts may not be mandatory in all cases , But it's best to run them , Because of the complexity of the data dictionary , We cannot ensure that all EE object .

Compile invalid object

Last , Recompile all invalid objects in the database ：

sqlplus / as sysdba @?/rdbms/admin/utlrp.sql

matters needing attention

Throughout the conversion process , What should we pay attention to ：

• Make sure the version number of your enterprise server software （ And patch versions ） The same version as the original standard server software ;
• Windows System , You must re create the database service after re installing the software （ adopt ORADIM）;
