Oracle autonomous database is really autonomous.. you do not have full DBA control..!!

Oracle autonomous database is really autonomous.. you do not have full DBA control..!!

Hi readers 

In a big conversation I had many months ago with Andrew Holdsworth ( Vice President of Real World Performance at Oracle Corp. ) he clarified me how autonomous works inside.. it’s very simple.. no indexes.. no any complex objects to speed up.. just the everything rely on the huge power of exadata.. + artificial intelligence, machine learning, and blockchain technology into its cloud-based services.

Exadata reads huge quantity of data so fast..

Exadata writes data so fast..

Exadata communication is so fast.. the disks are so fast..

So.. the autonomous concept is very simple.. use the HUGE POWER of exadata to process in a plain mode.. + ( advanced techniques of artificial intelligence, machine learning, and blockchain technology )  and you will have great predictable results.. simple like that.. that’s why in autonomous you can not create indexes or any other structure that affects a kind plain processing mode..

that;s why in autonomous.. you do not manage the database parameters.. etc.. it’s just to use the big BULL to drag the load.. simple like that..

See vestiges of that concept in this article. Click the image or the link down below.

Oracle 12cR2: Cross-Platform PDB Transport Using XTTS

Oracle 12cR2: Cross-Platform PDB Transport Using XTTS

Hi Readers

Let’s see how we can perform this process:

  1. Verify the prerequisites: The source PDB must be closed in MOUNTED mode and the COMPATIBLE parameter must be set to 12.2 or higher.

  2. Start an RMAN session and connect to the CDB instance of the PDB to be transported.

  3. For performing cross-platform PDB transport, you may need the exact name of the destination platform to which you are transporting data and may need to verify that the destination platform is of the same endian format.

    SQL> SELECT PLATFORM_ID, PLATFORM_NAME, ENDIAN_FORMAT FROM V$TRANSPORTABLE_PLATFORM
    WHERE UPPER(PLATFORM_NAME) LIKE ‘%LINUX%’;

  4. Back up the source PDB by using the BACKUP command with TO PLATFORM or FOR TRANSPORT. The new UNPLUG INTO clause creates the XML file containing the metadata of the PDB—tablespaces list, datafiles list, options, and parameters values. The FORMAT clause indicates the directory where the backup sets containing the data required for cross-platform database transportation are stored on the source host.

    In the first example in the slide, the conversion will take place on the source host and the files stored in the /bkp_dir directory are converted for the Linux x86 64-bit platform. In the second example, the conversion will take place on the destination host during the restore command and the files stored in /bkp_dir directory on the source host are not converted yet.

  1. Disconnect from the source CDB.

  2. Move the backup sets and the XML file created by the BACKUP command to the

    destination host. You can use operating system utilities to move the backup sets and the XML file from the source host to the destination host.

  3. Connect to the destination CDB, to which the PDB must be transported. Ensure that the destination CDB is opened.

  4. Use the RESTORE command to restore the files for the newly created PDB to the target location, and plug the files into the new PDB by using the new USING clause.

Oracle 12cR2: Cross-Platform Transportable PDB

Oracle 12cR2: Cross-Platform Transportable PDB

Hi Readers

Oracle Database 12.1 allows you to transport database or tablespace backup sets with conversion at source or destination for same endian platforms.

Oracle Database 12.2 includes cross-platform PDB backup and restore into a CDB by unplugging at backup step and plugging at restore step as long as the source platform and destination platform have the same endian format. For a cross-endian migration, the tablespaces have to be exported and imported with Data Pump, either using the conventional expdp/impdp or the Full Transportable expdp/impdp.

  1. Before backing the PDB, ensure that the prerequisites are satisfied.

  2. Determine the location of the endian conversion.

    • –  The FOR TRANSPORT clause creates a cross-platform backup indicating that the backup set can be transported to any destination database.

    • –  The TO PLATFORM clause indicates that the conversion performs on the source database for a specific platform and can be restored on that specific platform.

  3. Use the BACKUP FOR TRANSPORT or TO PLATFORM command to create a cross- platform PDB backup set on the source host. The new UNPLUG INTO clause creates the XML file containing the metadata for the PDB.

    1. Use any operating system utilities to transfer the created backup set and XML file.

    2. Use the RESTORE FOREIGN command to restore the cross-platform PDB backup set on the destination host. The new USING clause uses the XML file to plug the appropriate files for the new PDB.

    3. Open the PDB.

Oracle 12cR2: Upgrading a Single Regular PDB from 12.1 to 12.2

Upgrading a Single Regular PDB from 12.1 to 12.2

Hi Readers 

You can also upgrade a specific PDB without upgrading the whole CDB:

  1. Prepare the PDB to be unplugged and upgraded in another CDB by executing the same jar file as in the previous slide but only on the PDB. The fixup scripts and log files are generated in the pre-upgrade directory of the source database, in the $ORACLE_BASE/cfgtoollogs/SID/preupgrade directory. Execute the preupgrade_fixups_<PDB>.sql script in the PDB.

  2. Close the PDB from the 12.1 CDB to unplug it. Then plug it into the target 12.2 CDB.

  3. Open the PDB in the target 12.2 CDB in upgrade mode and upgrade it to 12.2.

         $ cd $ORACLE_HOME/rdbms/admin
    
         $ ./catctl.pl -c 'PDB1' -l /tmp/upgrade catupgrd.sql
    
  4. Finally close and open the PDB in normal mode. Use the catcon.pl script to execute the postupgrade_fixups.sql and utlrp.sql scripts. You can verify that all issues have been fixed by running the utlu122s.sql script.

In case the PDB is migrated to an application root, shared objects can be marked as metadata-linked or data-linked by using the DBMS_PDB.SET_METADATA_LINKED or DBMS_PDB.SET_DATA_LINKED or DBMS_PDB.SET_EXT_DATA_LINKED procedures. The user responsible for the migration can be granted EXECUTE on the new DBMS_PDB_ALTER_SHARING package rather than on the DBMS_PDB package to avoid enabling the user to execute other DBMS_PDB procedures.

Oracle 12cR2: Controlling the Degree of Parallelism of Queries

Controlling the Degree of Parallelism of Queries

Hi Readers 

Oracle Database 12.2 introduces a new instance parameter to control the Degree of Parallelism of queries, which involves a containers() construct.

By default, a query involving a containers() construct uses a DOP that is equal to the following value:

  • In the case of a query in the CDB root, the value is (1 + number of open PDBs).

  • In the case of a query in an application root, the value is (1 + number of open application PDBs).

    If the value of this parameter is less than 65535, the value is used as the DOP for all queries involving containers():

  • In the session if the value was set at the session level

  • In the instance if the value was set at the system level

Oracle 12cR2 (Tip): Local UNDO Mode Versus Shared UNDO Mode

Local UNDO Mode Versus Shared UNDO Mode

Hi Readers

Using the local UNDO mode is required when cloning a PDB in hot mode or performing a near-zero downtime PDB relocation or refreshing PDBs or using proxy PDBs.

You can set a CDB in local UNDO mode either at CDB creation or by altering the CDB property.

  • When the database property LOCAL_UNDO_ENABLED is FALSE, which is the default, there is only one UNDO tablespace that is created in the CDB root and that is shared by all containers.

  • When LOCAL_UNDO_ENABLED is TRUE, every container in the CDB uses local undo and each PDB must have its own local UNDO tablespace. To maintain ease of management and provisioning, UNDO tablespace creation happens automatically and does not require any action from the user. When a PDB is opened and an UNDO tablespace is not available, it is automatically created.
