Oracle Data Guard Tutorial - Open the Standby Read Only (Part 2 of 4)
 
16:49
This tutorial provides a quick review of what Data Guard is, and then goes on to show how you can extract value from Data Guard in every-day usage: how you can use it to enhance performance, and to reduce (yes, reduce!) your need for Oracle licences. Opening the standby database read-only. This has in fact been possible since the automation of redo transport and redo apply when it was first introduced in release 8i. Redo is received on the standby database but is not applied. So the redo is written to the RFS, slave to standby logs, archive to standby logs into archive logs but there's no apply done. So recoverability is not compromised. There's still no danger being lots of data. You're still receiving. The thing is open read-only. What does that mean? It means you can run queries against it. You can offload all your heavyweight queries from the primary to the standby. When I say all of them, even queries that require vast massive temporary space, those horrendous queries, those doing hash joins between multi gigabyte tables, they'll be generating many gigabytes of temporary data. You can write temporary data. Provided that you're using proper temporary tablespaces which you're certain you should be, you can run any query no matter how big, no matter how much temporary data it needs. You can also write audit data and this is important because with version 11, there's quite a lot of auditing enabled by default. By default, that auditing goes to the database, writing database tables. And you can't write to a database table in a read-only database. That we can configure for automatic switching and direct the audit records to the operating system or the trail instead. The queries you run, why is this such a good facility? First, you're taking stress off the primary. I'm sure that we're all DBAs here and we all know how difficult it is to tune your database or a concurrent workload that includes both high volume DML and includes heavyweight queries. Basically, you can't tune that way at all. Offloading the queries to the physical standby will reduce a lot of stress from the primary. So your DML should run significantly better and you can even do a certain amount of tuning on the standby to tune for optimal query performance. The most obvious tuning one would do, would be the memory parameters. No one could for example give the primary a massive PGA aggregate target and the much smaller SGA target or use indeed automatic memory management, perhaps cell tuning. One can adjust many parameters to do with tuning the optimizer to drive the optimizer to a certain execution plan, to exploit the environments. All that can be done on an open read-only database. How does one do it? It really couldn't be simpler. If we look at my physical standby here, this thing database role, physical standby - and if we select the open mode from v$ database, we find this in mount mode. How do we actually open at read-only? First off, we have to stop the recovery process because remember redo is received but no applied. You have to cancel the recovery. So "alter database recover managed standby database cancel." That will give us a read consistent version of the database. The command is intelligent enough to know that there might be incomplete transactions. Long-run transactions could've been partially received. We will end up with a read consistent version. To cancel it, all we do is alter database open read-only. It is that simple.

Migration of  Non-Container Database to Pluggable-PART II- Oracle 12C Administration
 
37:16
Non-Container Name =NCDB convert to PDB-NCDB Container DB Name=CDB =========================== Steps for Conversion. Step 1. Cleanly Shutdown the Non-CDB Database Instance. ==- set environment to NCDB ==- sqlplus / as sysdba ==- Shutdown immediate Step 2. Once You Have Cleanly Shutdown the Database, Start Up the database in Mount Exclusive Mode and Open the Database in Read-Only Mode. ==- set environment to NCDB ==- sqlplus / as sysdba ==- startup mount exclusive ==- alter database open read only; Step 3. Generate a Pluggable Database Manifest File from the Non-Container Database. ==- set environment to NCDB ==- sqlplus / as sysdba ==- exec dbms_pdb.describe (pdb_descr_file=-'E:\app\oracle\manifest\NCDB_manifest_file.xml'); Step 4. Shutdown the NON-CDB file Once Step 3 Completes Successfully. ==- Set environment to NCDB ==- sqlplus / as sysdba ==- shutdown immediate Step 5. Start the CDB (CDB) if it’s Not Already Up and Check the Compatibility with CDB. ==- set environment to CDB ==- sqlplus / as sysdba ==- startup (If not up) ==- Run below at SQL prompt. SET SERVEROUTPUT ON; DECLARE Compatible CONSTANT VARCHAR2(3) :=CASE DBMS_PDB.CHECK_PLUG_COMPATIBILITY (pdb_descr_file =- 'E:\app\oracle\manifest\NCDB_manifest_file.xml') WHEN TRUE THEN 'YES' ELSE 'NO' END; BEGIN DBMS_OUTPUT.PUT_LINE(compatible); END; / Step 6. Once it Completes Successfully, Query PDB_PLUG_IN_VIOLATIONS View from CDB Database for Any Errors. ==- set environment to CDB ==- sqlplus / as sysdba ==- select name, cause, type, message, status from PDB_PLUG_IN_VIOLATIONS where name='NCDB'; Note: "There should be no violations reported. If there are any, you need to fix it before proceeding". Step 7. Connect to the CDB Where Database has to be Plugged in Using the Noncdb Manifest File and Plug the PDDB12C Database. ==- set environment to CDB ==- sqlplus / as sysdba ==- CREATE PLUGGABLE DATABASE NCDB USING 'E:\app\oracle\manifest\NCDB_manifest_file.xml' COPY FILE_NAME_CONVERT = ('E:\APP\ORACLE\ORADATA\NCDB\', 'E:\app\oracle\oradata\CDB1\'); Note: "Below options are supported and you can chose one based on the env" 1) COPY: The datafiles of noncdb remains intact and it is copied to create PDBs at new locations and keep original datafiles intact at the original location. (This would mean that a noncdb database would still be operational after the creation of a PDB). 2) MOVE: The datafiles of noncdb are moved to a new location to create a PDB. In this case, noncdb database would not be available after a PDB is created. NOCOPY: The datafiles of noncdb are used to create a PDB2 and it uses same existing location. In this case, a noncdb database would not be available after a PDB is created. You can use FILE_NAME_CONVERT parameter to specify the new location of the datafiles while using COPY or MOVE option. Step 8. Once Step 7 Completes Successfully, Switch to the PDB Container and Run the "$ORACLE_HOME/rdbms/admin/noncdb_to_pdb.sql". ==- set environment to CDB ==- sqlplus / as sysdba ==- alter session set container=NCDB ==- @$ORACLE_HOME/rdbms/admin/noncdb_to_pdb.sql Step 9. Startup the PDB and Check the Open Mode. ==- set environment to CDB ==- sqlplus / as sysdba ==- ALTER PLUGGABLE DATABASE OPEN; ==-SELECT name, open_mode FROM v$pdbs; ==================================== Hi Folks, Greetings!!

Migration from Non-Container to PDB database-PART I- Oracle 12C Administration
 
09:30
Non-Container Name =NCDB convert to PDB-NCDB Container DB Name=CDB =========================== Steps for Conversion. Step 1. Cleanly Shutdown the Non-CDB Database Instance. ==- set environment to NCDB ==- sqlplus / as sysdba ==- Shutdown immediate Step 2. Once You Have Cleanly Shutdown the Database, Start Up the database in Mount Exclusive Mode and Open the Database in Read-Only Mode. ==- set environment to NCDB ==- sqlplus / as sysdba ==- startup mount exclusive ==- alter database open read only; Step 3. Generate a Pluggable Database Manifest File from the Non-Container Database. ==- set environment to NCDB ==- sqlplus / as sysdba ==- exec dbms_pdb.describe (pdb_descr_file=-'E:\app\oracle\manifest\NCDB_manifest_file.xml'); Step 4. Shutdown the NON-CDB file Once Step 3 Completes Successfully. ==- Set environment to NCDB ==- sqlplus / as sysdba ==- shutdown immediate Step 5. Start the CDB (CDB) if it’s Not Already Up and Check the Compatibility with CDB. ==- set environment to CDB ==- sqlplus / as sysdba ==- startup (If not up) ==- Run below at SQL prompt. SET SERVEROUTPUT ON; DECLARE Compatible CONSTANT VARCHAR2(3) :=CASE DBMS_PDB.CHECK_PLUG_COMPATIBILITY (pdb_descr_file =- 'E:\app\oracle\manifest\NCDB_manifest_file.xml') WHEN TRUE THEN 'YES' ELSE 'NO' END; BEGIN DBMS_OUTPUT.PUT_LINE(compatible); END; / Step 6. Once it Completes Successfully, Query PDB_PLUG_IN_VIOLATIONS View from CDB Database for Any Errors. ==- set environment to CDB ==- sqlplus / as sysdba ==- select name, cause, type, message, status from PDB_PLUG_IN_VIOLATIONS where name='NCDB'; Note: "There should be no violations reported. If there are any, you need to fix it before proceeding". Step 7. Connect to the CDB Where Database has to be Plugged in Using the Noncdb Manifest File and Plug the PDDB12C Database. ==- set environment to CDB ==- sqlplus / as sysdba ==- CREATE PLUGGABLE DATABASE NCDB USING 'E:\app\oracle\manifest\NCDB_manifest_file.xml' COPY FILE_NAME_CONVERT = ('E:\APP\ORACLE\ORADATA\NCDB\', 'E:\app\oracle\oradata\CDB1\'); Note: "Below options are supported and you can chose one based on the env" 1) COPY: The datafiles of noncdb remains intact and it is copied to create PDBs at new locations and keep original datafiles intact at the original location. (This would mean that a noncdb database would still be operational after the creation of a PDB). 2) MOVE: The datafiles of noncdb are moved to a new location to create a PDB. In this case, noncdb database would not be available after a PDB is created. NOCOPY: The datafiles of noncdb are used to create a PDB2 and it uses same existing location. In this case, a noncdb database would not be available after a PDB is created. You can use FILE_NAME_CONVERT parameter to specify the new location of the datafiles while using COPY or MOVE option. Step 8. Once Step 7 Completes Successfully, Switch to the PDB Container and Run the "$ORACLE_HOME/rdbms/admin/noncdb_to_pdb.sql". ==- set environment to CDB ==- sqlplus / as sysdba ==- alter session set container=NCDB ==- @$ORACLE_HOME/rdbms/admin/noncdb_to_pdb.sql Step 9. Startup the PDB and Check the Open Mode. ==- set environment to CDB ==- sqlplus / as sysdba ==- ALTER PLUGGABLE DATABASE OPEN; ==-SELECT name, open_mode FROM v$pdbs;
