- Database Rolling Upgrade using Transient Logical Standby (SQL Apply)
- Allows for running different database versions during rolling upgrade window.
- Gives you more time to test the new version, before activating it.
- In case you already use Data Guard – no additional hardware/storage(*) footprint,license fees and knowledge(*) necessary.
- Near zero downtime – reduced to one switchover (two, if you go back).
- Fairly simple method, compared to some other replication technologies.But with some restrictions.
Environment Details:- Lets Start the Demo:-
- We have primary & standby database running in 11.2.0.4 Here
- Already installed oracle 12.2.0.1 binaries on both nodes
Step1:-Check the Standby database status
SQL> SELECT ARCH.THREAD# "Thread", ARCH.SEQUENCE# "Last Sequence Received", APPL.SEQUENCE# "Last Sequence Applied", (ARCH.SEQUENCE# - APPL.SEQUENCE#) "Difference" FROM (SELECT THREAD# ,SEQUENCE# FROM V$ARCHIVED_LOG WHERE (THREAD#,FIRST_TIME ) IN (SELECT THREAD#,MAX(FIRST_TIME) FROM V$ARCHIVED_LOG GROUP BY THREAD#)) ARCH,(SELECT THREAD# ,SEQUENCE# FROM V$LOG_HISTORY WHERE (THREAD#,FIRST_TIME ) IN (SELECT THREAD#,MAX(FIRST_TIME) FROM V$LOG_HISTORY GROUP BY THREAD#)) APPL WHERE ARCH.THREAD# = APPL.THREAD# ORDER BY 1; Thread Last Sequence Received Last Sequence Applied Difference ---------- ---------------------- --------------------- ---------- 1 14 14 0
Step2:-Stop the mrp process
SQL> ALTER DATABASE RECOVER MANAGED STANDBY DATABASE CANCEL;
Database altered.
Step 3:-Open the database in read only mode
SQL>ALTER DATABASE OPEN READ ONLY;
Database altered.
Step 4:-Ensure Flashback is ON in both primary and standby databases
SQL>SELECT FLASHBACK_ON FROM V$DATABASE;
FLASHBACK_ON
————–
YES
Step 5:-Create restore point at Primary database
SQL>CREATE RESTORE POINT BEFORE_UPGRADE GUARANTEE FLASHBACK DATABASE;
Restore point created.
SQL>select GUARANTEE_FLASHBACK_DATABASE,NAME from v$restore_point;
GUARANTEE_FLASHBACK_DATABASE Name
———————————– ——————–
YES BEFORE_UPGRADE
START APPLY PROCESS:
Step 6:- Start the log apply process by executing the below query in standby and make sure the standby is in sync with primary
SQL>ALTER DATABASE RECOVER MANAGED STANDBY DATABASE DISCONNECT FROM SESSION;
Database altered.
LOGICAL STANDBY DATABASE CONVERSION:
Step 1:-Stop the media recovery at standby database
SQL>ALTER DATABASE RECOVER MANAGED STANDBY DATABASE CANCEL;
Database altered.
Step 2:-Build data dictionary at primary database for logical standby database
SQL>ALTER DATABASE RECOVER MANAGED STANDBY DATABASE CANCEL;
Database altered.
Step 3:-Convert physical standby database to logical standby database (ensure database is not in open state)
SQL>ALTER DATABASE CLOSE;
Database altered.
SQL>ALTER DATABASE RECOVER TO LOGICAL STANDBY KEEP IDENTITY;
Database altered.
Step 4:-Restart the database, once it gets started logical standby role will be enabled
SQL> SHUT IMMEDIATE
SQL> STARTUP
SQL>SELECT DB_UNIQUE_NAME,DATABASE_ROLE FROM V$DATABASE;
DB Unique Name Database Role
———————— —————-
ORCL_PROD102 LOGICAL STANDBY
Step 5:-Start the log shipping process at logical standby database
SQL>ALTER DATABASE START LOGICAL STANDBY APPLY IMMEDIATE;
Database altered.
Check the alert log for the Logminer process would have been started in the background:-
$tail -100f alert_ORCL.log
LOGSTDBY Apply process AS02 started with server id=2 pid=46 OS id=38615
LOGMINER: End mining logfile for session 1 thread 1 sequence 16, /oradb/app/oracle/archive/orcl_prod102/orclp102_1_16_981941460.arc

LOGMINER: Begin mining logfile for session 1 thread 1 sequence 19, /oradb/app/oracle/oradata/ORCL_PROD102/redo05.log
Also you can notice archive log sequence got reset in Standby:-
SQL>ARCHIVE LOG LIST
Database log mode Archive Mode
Automatic archival Enabled
Archive destination /oradb/app/oracle/archive/orcl_prod102
Oldest online log sequence 1
Next log sequence to archive 2
Current log sequence 2
Step 6:-Check if the data dictionary build is completed by executing below query in primary
SQL>SELECT * FROM V$LOGSTDBY_STATE WHERE STATE = ‘LOADING DICTIONARY’;
no rows selected
START THE UPGRADE PROCESS:
Step 1:-Upgrade Logical standby database to Oracle 12c (12.2.0.1.0) database version
Create the below directory before starting the upgrade and run the preupgrade.jar from Oracle 12.2.0.1 home as below and check the logs in the below created log directory if any prerequisite as to be done before the upgrade:-
$ mkdir -p /oradb/app/oracle/scripts/logs/12cR2
$ cd /oradb/app/oracle/scripts/logs/12cR2
$ sqlplus ‘/ as sysdba’
$ /oradb/app/oracle/product/11.2.0.4/db_1/jdk/bin/java -jar /oradb/app/oracle/product/12.2.0.1/db_1/rdbms/admin/preupgrade.jar FILE TEXT DIR /oradb/app/oracle/scripts/logs/12cR2
Upgrade can be done either using DBUA or Manual upgrade. Here we followed manual upgrade:
Shutdown logical standby database and it’s listener at Oracle 11g (11.2.0.4)
SQL>SHUTDOWN IMMEDIATE
$ lsnrctl stop

Step 2:-Copy listener.ora and tnsnames.ora to 12c ORACLE_HOME and edit listener.ora to 12c ORACLE_HOME. Copy pfile and password file to Oracle 12c (12.2.0.1.0) home
$ export ORACLE_HOME=/oradb/app/oracle/product/12.2.0.1/db_1
$ export PATH=$ORACLE_HOME/bin:$PATH
$ export ORACLE_SID=ORCL
$ sqlplus ‘/ as sysdba’
SQL> STARTUP UPGRADE
Step 3:-Start the manual upgrade process using catctl.pl as below
$ cd $ORACLE_HOME/rdbms/admin

Step 5:-Start the log apply process at Logical standby which is now Oracle 12c (12.2.0.1.0) version. Primary still in Oracle 11g (11.2.0.4.0) version
SQL> ALTER DATABASE START LOGICAL STANDBY APPLY;
Database altered.
SWITCHOVER FROM LOGICAL STANDBY TO PRIMARY:-
Step 1:-Switchover the roles. Now primary database will become Oracle 11g (11.2.0.4.0) Logical standby and other side Oracle 12c (12.2.0.1.0) will be as primary database
1) Execute the below query at primary(Oracle 11.2.0.4):
SQL>ALTER DATABASE COMMIT TO SWITCHOVER TO LOGICAL STANDBY;
Database altered.
2) Execute the below query at standby(Oracle 12.2.0.1):
SQL> ALTER DATABASE COMMIT TO SWITCHOVER TO PRIMARY;
Database altered.
3) Now the Primary database become as Standby database:
SQL> SELECT DB_UNIQUE_NAME,DATABASE_ROLE FROM V$DATABASE;
DB Unique Name Database Role
———————— —————-
ORCL_PROD101 LOGICAL STANDBY
4) Standby database become Primary database:
SQL> SELECT DB_UNIQUE_NAME,DATABASE_ROLE FROM V$DATABASE;

—————————— —————-
ORCL_PROD102 PRIMARY
Step 2:-We cannot directly convert Logical standby database to physical standby database, hence flashback to guarantee restore point which was created prior to upgrade
SQL> SHUTDOWN IMMEDIATE
SQL> STARTUP MOUNT
SQL> FLASHBACK DATABASE TO RESTORE POINT BEFORE_UPGRADE;
Flashback complete.
SQL> ALTER DATABASE CONVERT TO PHYSICAL STANDBY;

Now the current logical standby database Oracle 11g (11.2.0.4.0) becomes physical standby database. i.e Logical to physical conversion:-
Step 1:-Shutdown database and start Physical standby database with Oracle 12c (12.2.0.1.0) binary

Step 4:-Check the flashback restore point and drop it
SQL> select GUARANTEE_FLASHBACK_DATABASE,NAME from v$restore_point;
GUARANTEE_FLASHBACK_DATABASE Name
—————————— ————————
YES BEFORE_UPGRADE
SQL> select flashback_On from v$database;
FLASHBACK_ON
——————
YES
SQL> alter database flashback off;
Database altered.
SQL> select flashback_On from v$database;
FLASHBACK_ON
——————
RESTORE POINT ONLY
SQL> drop restore point BEFORE_UPGRADE;
Restore point dropped.
SQL> select flashback_On from v$database;
FLASHBACK_ON
——————
NO
SQL> ALTER SYSTEM SET COMPATIBLE = ‘12.2.0.1.0’ SCOPE=SPFILE;
System altered.
SQL> ALTER SESSION SET nls_date_format=’DD-MON-YYYY HH24:MI:SS’;
Session altered.

CURRENT PRIMARY DATABASE:-
Step 1:-Convert primary database to physical standby database and shutdown the database. It can be used in future
SQL> ALTER DATABASE COMMIT TO SWITCHOVER TO PHYSICAL STANDBY WITH SESSION SHUTDOWN;
Database altered.
CURRENT STANDBY DATABASE:-
SQL> ALTER DATABASE COMMIT TO SWITCHOVER TO PRIMARY;
Database altered.
Step 2:-Now open the database
SQL> ALTER DATABASE OPEN;
Database altered.
Step 3:-Check the components have been upgraded to 12c
SQL> col COMP_ID format A10
SQL> col COMP_NAME format A30
SQL> col VERSION format A10
SQL> col STATUS format A15
SQL> SELECT SUBSTR(COMP_ID,1,15) COMP_ID,
SUBSTR(COMP_NAME,1,30) COMP_NAME,
SUBSTR(VERSION,1,10) VERSION,STATUS
FROM DBA_REGISTRY
/
