Database Upgrade from 12c to 19c using Datapump

Database Upgrade from 12c to 19c using Datapump

Overview steps:

Step:1 Check the database size in source.
Step:2 check which tablespace holds the schema objects.
Step:3 compile invalid objects in source.
step:4 check the  count of invalid dba_objects in the source.
Step:5 create a directory for export purpose both in OS level and database level.
Step:6 Estimate the size of dumpfile, so that we can know when will the export get completed.
Step:7 export the database(TANSTAL).
Step:8 create a fresh database for import.
Step:9 Now create a directory in both OS level and database level for import purpose in the newly created database.
Step:10 import the database.(ZHIGOMA)
Step:11 Post upgrade steps in target database.
               11.1 compile invalid objects in target database.
               11.2 check whether any invalid objects present.
               11.3 Run the query to check for currently installed database components.

Step:12  Verify the timezone of the upgraded database.

Step:13  Check the CONSTRAINTS count in both source & target.it is used to display the constraints that are defined in the database.

Step:1 Check the database size in source .

SQL> col "Database Size" format a20
col "Free space" format a20
col "Used space" format a20
select round(sum(used.bytes) / 1024 / 1024 / 1024 ) || ' GB' "Database Size"
, round(sum(used.bytes) / 1024 / 1024 / 1024 ) -
round(free.p / 1024 / 1024 / 1024) || ' GB' "Used space"
, round(free.p / 1024 / 1024 / 1024) || ' GB' "Free space"
from (select bytes
from v$datafile
union all
select bytes
from v$tempfile
union all
select bytes
from v$log) used
, (select sum(bytes) as p
from dba_free_space) free
group by free.p

Database Size             Used space         Free space
-------------------- -------------------- --------------------
    2 GB                    2 GB               0 GB

SQL>

Step:2 execute the following query to check which tablespace holds the schema objects.

set pagesize 130
break on Tablespace on Owner
column Objects format A20
select Tablespace_Name,Owner,COUNT(*)||’ tables’ Objects
from DBA_TABLES
group by Tablespace_Name,Owner
union
select Tablespace_Name, Owner, COUNT(*)||’ indexes’ Objects
from DBA_INDEXES
group by Tablespace_Name, Owner;

Step:3 compile invalid objects in source to reduce dependencies, so that we can find the best way to recompile it.

SQL> @?/rdbms/admin/utlrp.sql

COMP_TIMESTAMP UTLRP_BGN 2021-01-31 20:19:36

DOC> The following PL/SQL block invokes UTL_RECOMP to recompile invalid
DOC> objects in the database. Recompilation time is proportional to the
DOC> number of invalid objects in the database, so this command may take
DOC> a long time to execute on a database with a large number of invalid
DOC> objects.
DOC>
DOC> Use the following queries to track recompilation progress:
DOC>
DOC> 1. Query returning the number of invalid objects remaining. This
DOC> number should decrease with time.
DOC> SELECT COUNT(*) FROM obj$ WHERE status IN (4, 5, 6);
DOC>
DOC> 2. Query returning the number of objects compiled so far. This number
DOC> should increase with time.
DOC> SELECT COUNT(*) FROM UTL_RECOMP_COMPILED;
DOC>
DOC> This script automatically chooses serial or parallel recompilation
DOC> based on the number of CPUs available (parameter cpu_count) multiplied
DOC> by the number of threads per CPU (parameter parallel_threads_per_cpu).
DOC> On RAC, this number is added across all RAC nodes.
DOC>
DOC> UTL_RECOMP uses DBMS_SCHEDULER to create jobs for parallel
DOC> recompilation. Jobs are created without instance affinity so that they
DOC> can migrate across RAC nodes. Use the following queries to verify
DOC> whether UTL_RECOMP jobs are being created and run correctly:
DOC>
DOC> 1. Query showing jobs created by UTL_RECOMP
DOC> SELECT job_name FROM dba_scheduler_jobs
DOC> WHERE job_name like 'UTL_RECOMP_SLAVE_%';
DOC>
DOC> 2. Query showing UTL_RECOMP jobs that are running
DOC> SELECT job_name FROM dba_scheduler_running_jobs
DOC> WHERE job_name like 'UTL_RECOMP_SLAVE_%';
DOC>#

PL/SQL procedure successfully completed.

COMP_TIMESTAMP UTLRP_END 2021-01-31 20:19:39

DOC> The following query reports the number of invalid objects.
DOC>
DOC> If the number is higher than expected, please examine the error
DOC> messages reported with each object (using SHOW ERRORS) to see if they
DOC> point to system misconfiguration or resource constraints that must be
DOC> fixed before attempting to recompile these objects.
DOC>#

0

DOC> The following query reports the number of exceptions caught during
DOC> recompilation. If this number is non-zero, please query the error
DOC> messages in the table UTL_RECOMP_ERRORS to see if any of these errors
DOC> are due to misconfiguration or resource constraints that must be
DOC> fixed before objects can compile successfully.
DOC> Note: Typical compilation errors (due to coding errors) are not
DOC> logged into this table: they go into DBA_ERRORS instead.
DOC>#

Function created.

PL/SQL procedure successfully completed.

Function dropped.

PL/SQL procedure successfully completed.

step:4 check the  count of invalid dba_objects in the source.

SQL> select count(*) from dba_objects where status=’INVALID’;

COUNT(*)
----------
0

Step:5 create a directory for export purpose both in OS level and database level.

mkdir /u01/export

create directory export as '/u01/export';

Directory created

[oracle@orcldbs ~]$ mkdir export
[oracle@orcldbs ~]$ ls
12c.env Documents export oraprod.env Templates
19c.env Downloads Music Pictures utlrp.out
Desktop em13400_linux64-3.zip oradiag_oracle Public Videos

Create  a table employee in the user : rahul.

Step:6 Estimate the size of dumpfile by this we are able to know the completion time of export activity.

[oracle@orcldbs export]$ expdp directory=export full=Y nologfile=Y estimate_only=Y

yes now we can login to the zhigoma database and we can verify our user(rahul) and the table(employee) in that user is  imported into this database or not.

We have successfully upgraded our database from 12 c to 19c using datapump !!!!

DBVERIFY

DBVERIFY

It is an external command-line utility that performs a physical data structure integrity check. It can be used on offline or online databases, as well on backup files.
You use DBVERIFY primarily when you need to ensure that a backup database (or datafile) is valid before it is restored, or as a diagnostic aid when you have encountered data corruption problems.

Overview:

  • Verifying the table and tablespaces
  • Checking the header block for the table
  • Stimulating a corruption
  • Recovering the block using RMAN
  • Verifying using DATABASE BLOCK CORRUPTION

Step 1:

Verifying the TABLESPACE_NAME and its associated SEGMENT_NAME.

SQL> select SEGMENT_NAME,TABLESPACE_NAME from dba_segments where OWNER=’SCOTT’;

SEGMENT_NAME TABLESPACE_NAME
————— ——————————
SALGRADE USERS
DEPT USERS
EMP USERS
PK_DEPT USERS
PK_EMP USERS

Step 2:

By issuing the below command we can check the header block for the table ‘DEPT’

SELECT header_block FROM dba_segments WHERE segment_name=’DEPT’;

SQL> select file_name from dba_data_files;

FILE_NAME

/u01/app/oracle/oradata/ORACLE19C/datafile/o1_mf_users_j21snyfk_.dbf
/u01/app/oracle/oradata/ORACLE19C/datafile/o1_mf_undotbs1_j21snxbn_.dbf
/u01/app/oracle/oradata/ORACLE19C/datafile/o1_mf_system_j21skfkg_.dbf
/u01/app/oracle/oradata/ORACLE19C/datafile/o1_mf_sysaux_j21sn40n_.dbf

Step 3:

Command to corrupt the block ,

[oracle@oracle19c ~]$ dd of=/u01/app/oracle/oradata/ORACLE19C/datafile/o1_mf_users_j21snyfk_.dbf bs=8192 conv=notrunc seek=347 << EOF

corruption test
EOF
0+1 records in
0+1 records out
16 bytes (16 B) copied, 4.9494e-05 s, 323 kB/s

Step 4:

To flush the buffer cache we need to provide the below command

SQL> ALTER SYSTEM FLUSH BUFFER_CACHE;

System altered.

Step 5:

Selecting the corrupted table , but it shows error

Step 6:

Viewing the corrected block in the database

select * from V$DATABASE_BLOCK_CORRUPTION;

Step 7:

Command to verify the corrupted block across the datafile using the below command

dbv file=/u01/app/oracle/oradata/ORACLE19C/datafile/o1_mf_users_j21snyfk_.dbf blocksize=8192

Step 8:

Command to recover the block and datafile using RMAN,
The datafile and corrupted block we can check it in the previous step ‘DBVERIFY-DBV’ command

recover datafile 7 block 347;

Verification’s:

After recovering there are no rows found in database block corruption ,
And after issuing dbverify command ,there we can see the marked corruption is ‘0’

Patch Oracle Home 19c (19.3 to 19.9)

 

Here I am going to upgrade steps of Oracle Database Home 19c from 19.3 to 19.9 within Oracle Linux 8.2 The patch is 31771877 – Database Release Update 19.9.0.0.201020 Prerequisites: “You must use the OPatch utility version 12.2.0.1.19 or later to apply this patch.” from READ ME of the Patch 31771877 Checking current ORACLE_HOME – OPATCH Version:

[oracle@db101:USA] ./opatch version
OPatch Version: 12.2.0.1.17 
OPatch succeeded.

Hope everyone is aware of how to upgrade the opatch utility. We need to take a backup of the existing patch and replace our new downloaded opatch in the ORACLE_HOME location.

Step 1: Install OPatch utility “6880880”:

Backup the Old OPatch utility 

[oracle@db101:USA] cd [oracle@db101:USA]ORACLE_HOME
[oracle@db101:USA] mv OPatch/ OPatch_backup

Set up the latest Optach Utility 12.2.0.1.23

[oracle@db101:USA] unzip p6880880_190000_Linux-x86-64.zip
[oracle@db101:USA] ./opatch version
OPatch Version: 12.2.0.1.23 
OPatch succeeded

Step 2: Install the patch 31771877

Stop all services using the Oracle HOME: Databases or Listeners, .. Install the Patch:

[oracle@db101:USA] unzip p31771877_190000_Linux-x86-64.zip
[oracle@db101:USA] cd 31771877/
[oracle@db101:USA] $ORACLE_HOME/OPatch/opatch apply

Step:3 Select a guest operating system, I have chosen the Linux operating system.

 

Step:4 Specify the virtual machine name and location of the virtual machine.

Step:5 Configure the maximum disk size I have configured the 200GB disk size and select the option store virtual disk as a single file.

 

Step:6 Specify the memory size of the virtual machine.

 

Step:7 Use  ISO image file, specify the OS location OEL 7(Linux 7) software.

Step:8 Set the Date and time, choose the timezone, region and city as Asia and Kolkata respectively.

Step:9 Select the base environment and adds on for selected environment, select all the check boxes for all the base environments.

 


Step:10 Specify the installation destination, here we can partition our storage either by  automatic partitioning or customized partitioning.

Step:11 Do the partition manually. Such as create the following mount points /boot , / , swap.

 

Step:12 This page asks for the confirmation, whether we can go with the configured partitions.

Step:13 Setup the password for the root user.

 

Step:14 We can create the user, I have created the user oracle and set up the password for the oracle user. Now we all set for the installation we can proceed further.

Step:15 Now we can login to the oracle user and get in to the VM.

Step:16 Choose the language as English(United states).

Step:17 Now we can use the Virtual Machine installed with Linux 7 OS and I checked my internet is working within  the VM by pinging google.com.

Change PDB name with DBNEWID Utility in 19c


DBNEWID Utility:

NID utility has been introduced with Oracle 10g to change the database name and id. Without NID changing the DBNAME is only possible by recreating the control files. Changing the DBID was not possible before, as this is the database unique identifier. Giving a database a new DBNAME is common after migration of a database instance using Data Guard or duplicate where DBNAME and DB_UNIQUE_NAME differs and shall be synchronized afterwards. In some situation an ORA-01103 error occurs and changing the DBNAME to a new value may be needed.

OVERVIEW:

  1. Verifying the pluggable database
  2. For rename the pluggable database, We need to open the database in Restricted Mode
  3. Set the container database name
  4. Renaming the pluggable database
  5. Open the pluggable database

Note : For an example , I am taking Source PDB “Mumbai” and renaming as “Noida”,  

Step 1:

Verifying the available pluggable database in our local CDB

SQL> select con_id,name,open_mode from v$Pdbs;

Step 2:

Before we need to rename the pluggable database ,We should bring the PDB close and open it in “RESTRICTED MODE”

alter pluggable database mumbai close;

Step 3:

Opening the PDB in restricted mode,

alter pluggable database mumbai open restricted;

Step 4:

Set the PDB “MUMBAI”

alter session set container=mumbai;

Step 5:

Here we are renaming the pluggable database name “mumbai” as “noida”

alter pluggable database rename global_name to noida;

Step 6:

Here we can check the renamed pdb by issuing the below command

select con_id,name,open_mode from v$Pdbs;

But , the database is in restricted mode so we need to open the database,

Now the database name has been changed .

Oracle Database In-Memory concepts in 19c

Version 19.8 has below updates:

New Features

The following major features are new in this release.

  • Database In-Memory Base LevelStarting with Oracle Database release 19c, version 19.8, you can enable the Database In-Memory Base Level by setting the INMEMORY_FORCE initialization parameter to BASE_LEVEL. The Base Level enables you to experiment with In-Memory features without purchasing the Oracle Database In-Memory option.When the Base Level is enabled, the IM column store size is limited to 16 GB for a CDB or non-CDB and for every database instance in an Oracle RAC database. Also, the compression level for all objects and columns is set to QUERY LOW automatically and transparently, and Automatic In-Memory is disabled. The CELLMEMORY feature is disabled for Oracle Exadata.
  • Starting with Oracle Database release 19c, version 19.8, you can use the CellMemory feature without enabling the IM column store by setting INMEMORY_FORCE=CELLMEMORY_LEVEL and INMEMORY_SIZE=0. With these settings, the IM column store is not enabled and queries can use CellMemory to scan objects.In previous releases of Oracle Database, in order to use the CellMemory feature, you were required to enable the IM column store, even if you had no intention of using it. This incurred the overhead of enabling the IM column store without any benefit.

 

Changes in Oracle Database Release 19c, Version 19.1

New Features

  • Database In-Memory Base LevelEnable the Database In-Memory Base Level by setting the INMEMORY_FORCE initialization parameter to BASE_LEVEL. The Base Level enables you to experiment with In-Memory features without purchasing the Oracle Database In-Memory option.When the Base Level is enabled, the IM column store size is limited to 16 GB for a CDB or non-CDB and for every database instance in an Oracle RAC database. Also, the compression level for all objects and columns is set to QUERY LOW automatically and transparently, and Automatic In-Memory is disabled. The CELLMEMORY feature is disabled for Oracle Exadata.
  • Database In-Memory wait on populateThe DBMS_INMEMORY_ADMIN.POPULATE_WAIT function initiates population of all INMEMORY objects that have a priority greater than or equal to the specified priority, and returns a status value for the population. A user-specified interval specifies the maximum time that the function waits before returning the value to the caller.
    • The ORACLE_HIVE and ORACLE_BIGDATA drivers are supported.
    • Parallel query is supported.
    • A full table scan populates an In-Memory external table. In previous releases, population required using the POPULATE or REPOPULATE procedure of DBMS_INMEMORY.
    • The In-Memory background processes, rather than a foreground process, now drop IM segments.Big Data and performance enhancements for In-Memory external tablesThis release introduces several manageability and performance improvements to the In-Memory external tables feature:
  • Hybrid partitioned tablesPartitions can reside in both Oracle Database segments and in external files and sources. This feature significantly enhances partitioning for Big Data SQL, where large portions of a table can reside in external partitions. Only the internal partitions of a hybrid partitioned table inherit the INMEMORY attribute.
  • Oracle Database Resource Manager automatically enabled for Database In-MemoryWhen INMEMORY_SIZE is greater than 0, the Resource Manager is automatically enabled.
  • Oracle Data Guard Multi-Instance Redo Apply supports the IM column storeSetting the initialization parameter ENABLE_IMC_WITH_MIRA to TRUE enables the IM column store and Data Guard Multi-Instance Redo Apply at the same time on an Active Data Guard standby database. By default, ENABLE_IMC_WITH_MIRA is FALSE.

In this article we are going to see datafile recovery when no backup exists and lost a datafile at the OS level and there are no current backups. we are in archivelog mode. we have all Archivelogs available since the datafile was created initially .We must have RMAN full backup and archivelogs to recover the datafile when no recent backup of datafile exists.

Step 1: New tablespace creation

SQL> startup
ORACLE instance started.
Total System Global Area         3019895280 bytes
Fixed Size                                     8901104 bytes
Variable Size                               738197504 bytes
Database Buffers                       2264924160 bytes
Redo Buffers                              7872512 bytes
Database mounted.
Database opened.
SQL> create tablespace inba datafile ‘/u01/app/oracle/oradata/INBAA/inba_01.dbf’ size 10m;

SQL> select file_name from dba_data_files where tablespace_name=’INBA’;

FILE_NAME

/u01/app/oracle/oradata/INBAA/inba_01.dbf

Step 2: Take RMAN whole database backup and plus archivelog

Step 3: Add a New Datafile to that Tablespace and verify that the new file is now a member of the tablespace.

SQL> alter tablespace inba add datafile ‘/u01/app/oracle/oradata/INBAA/inba_02.dbf’ size 10m;

Tablespace altered.

SQL> select file_name from dba_data_files where tablespace_name like ‘INBA’;

SQL> alter system switch logfile;

System altered.
SQL> /
System altered.
SQL> /
System altered.
SQL>

Step 4: Create a ‘emp’ table in that tablespace and perform some DML operation. Also after DML operations switch some logfile.

SQL> create table emp(id number) tablespace inba;

Table created.
SQL> insert into emp values(11);
1 row created.
SQL> insert into emp values(12);
1 row created.
SQL> insert into emp values(13);
1 row created.
SQL> insert into emp values(14);
1 row created.
SQL> insert into emp values(15);
1 row created.
SQL> select * from emp;

Step 5: In the OS Level,remove all files of that “INBA” tablespace including the newly added one (whose backup does not exist).

Step 6:- Try to bring the tablespace offline and we will get error message as follows

SQL> alter tablespace inba offline;

Tablespace altered.

Step 7: Check the status of tablespace and file_id of datafiles

SQL> select TABLESPACE_NAME,STATUS from dba_tablespaces;

TABLESPACE_NAME           STATUS
——————————          ———
SYSTEM                              ONLINE
SYSAUX                              ONLINE
UNDOTBS1                       ONLINE
TEMP                                 ONLINE
USERS                               ONLINE
INBA                                 OFFLINE

6 rows selected.

SQL> select file_id,file_name from dba_data_files where tablespace_name like ‘INBA’;

FILE_ID         FILE_NAME
———-         ——————————
5                  /u01/app/oracle/oradata/INBAA/inba_01.dbf
2                /u01/app/oracle/oradata/INBAA/inba_02.dbf

Step 8: Check RMAN backup of INBA tablespace

Now connect to RMAN and confirm that no backup exists for the newly added datafile FILE_ID 2. Then try to restore the DBWRTBS tablespace,  RMAN will create that newly added datafile as a part of the restore process.

Step 9: Tablespace restore

RMAN recovery through RESETLOGS

Description:- 

In this article we are going to see RMAN recovery through RESETLOGS.

What does a RESETLOGS do?

  • Archives the current online redo logs (if they are accessible) and then erases the contents of  the online redo logs and resets the log sequence number to 1.
  • Creates the online redo log files if they do not currently exist.
  • Updates all current datafiles and online redo logs and all subsequent archived redo logs with a new RESETLOGS SCN and time stamp.

The Recovery through Resetlogs feature provides the following benefits:

  • There is no need to perform a full backup after an incomplete recovery.There is no need to recreate a new standby database after a failover operation.
  • You can take incremental backups based on full backups of a previous incarnation when          you    use RMAN.
  • Block media recovery can restore backups from parent incarnation backups and recover the    corrupted blocks through a RESETLOGS operation.
  • You can use the newly generated logs with an earlier incarnation of the database.

Step 1:- Check the log_archive format as ‘%r’

SQL> show parameter log_archive_format

Note : To perform recovery through RESETLOGS you must have all archived logs generated after the most recent backup.  The database would not start if you remove the %r from the log archive format specification.

Oracle 10g introduces a new format specification for archived log files. This new format avoids overwriting archived redo log files with the same sequence number across incarnations.The format specification of the log_archive_format string “%”r represents the resetlogs id. It will ensure that a unique name is constructed for the archived redo log file during RMAN restore and as well as restoring via SQL*plus auto recovery mode.

What is an incarnation?

  • A database incarnation is created whenever you open the database with the RESETLOGS option.
  • The Current incarnation is the one in which the database is running at present
  • The incarnation from which the current incarnation branched after a ALTER DATABASE OPEN RESETLOGS was performed is called the Parent incarnation.
  • If you want to go back to some SCN which is not part of the Current database incarnation, we need to use the RESET DATABASE TO INCARNATION
    command as shown in the example below

Step 2:-Let us check what the current incarnation of the database

RMAN>

Step 3:- Note the CURRENT_SCN of the database.

SQL> select current_scn from v$database;

CURRENT_SCN

2406389

Step 4:- Now, let us make a change in the database which we will then try to undo by restoring  and recovering the database to a point in time before the media failure or as in this case, a wrong transaction has happened.

Simulate the wrong DML execution,

SQL> conn inba/inba
Connected.

SQL> create table student(id number);

Table created.
SQL> begin
for i in 1 .. 100000 loop
insert into student values(1);
end loop;
end;
/

SQL> select count(*) from student;

COUNT(*)

100000
SQL> delete from student where rownum < 1001;

1000 rows deleted.
SQL> commit;

Commit complete.
SQL> select count(*) from student;

COUNT(*)

99000
SQL> conn / as sysdba
Connected.

Step 5:- Shutdown and mount the  database

SQL> conn / as sysdba
Connected.
SQL> shut immediate
Database closed.
Database dismounted.
ORACLE instance shut down.
SQL> startup mount
ORACLE instance started.

Total System Global Area 3019895280 bytes
Fixed Size 8901104 bytes
Variable Size 738197504 bytes
Database Buffers 2264924160 bytes
Redo Buffers 7872512 bytes
Database mounted.
SQL>

Step 6:- Now we will rollback the database to an SCN before the delete operation was performed.

Step 11:- Open the database using resetlogs option

Now we open the database with the ALTER DATABASE OPEN RESETLOGS command and see that a new incarnation key (12) has been allocated to the database as the CURRENT incarnation.
