+ Name: SQL Developer SQLcl
+ Desc: Oracle SQL Developer Command Line (SQLcl) is a free command line 
+       interface for Oracle Database. It allows you to interactively or 
+       batch execute SQL and PL/SQL. SQLcl provides in-line editing, statement
+       completion, and command recall for a feature-rich experience, all while
+       also supporting your previously written SQL*Plus scripts.
+ Version: 20.4.1
+ Build: 20.4.1.351.1718
+
+Release Notes
+=============
+
+Ansiconsole as default SQLFormat
+--------------------------------
+From SQLcl 20.2, AnsiConsole Format is on by default.  This means that certain 
+features will not work as expect until the format is set to default.
+
+These include the SQL\*Plus features
+  * HEADING
+  * TTITLE
+  * BREAK
+  * COMPUTE
+
+SQL> set sqlformat default. 
+
+If you have extensive use of SQL\*Plus style reports, you need to unset
+sqlformat via login.sql or add it to your reports

+~~ to differentiate target status of a service along a database role
+~~ the services should be created with -l <role> option
+
+~~in the next exemple, we will create a GOTAL_WEB_APPLICATION service for primary database and a GOTAL_ADHOC_REPORTING on the read-only standby

+# Scripts
+
+### make-fedora-rpm.py
+
+Fedora-specific script that ties it all together. Run it like:
+
+    ./make-fedora-rpm.py
+
+What it does roughly:
+
+* Extracts all the .zip files in $scriptdir/new-builds/ to a temporary directory. The .zip files should contain all the build input for `make-driver-dir.py`. I prepopulate this with `fetch-latest-builds.py` but other people can use the build input mirror mentioned above.
+* Runs `make-driver-dir.py` on the unzipped output
+* Runs `make-virtio-win-rpm-archive.py` on the make-driver-dir.py output
+* Updates the virtio-win.spec
+* Runs `./make-repo.py`

+    
+### make-installer.py
+
+This uses a [virtio-win-guest-tools-installer.git](https://github.com/virtio-win/virtio-win-guest-tools-installer]) git submodule to build .msi installers
+for all the drivers. Invoking this successfully requires quite a few RPMs installed on the host
+
+* `wix-toolset-binaries`, example: https://resources.ovirt.org/pub/ovirt-master-snapshot/rpm/fc32/noarch/wix-toolset-binaries-3.11.1-2.fc32.noarch.rpm
+* `ovirt-guest-agent-windows`, example: https://resources.ovirt.org/pub/ovirt-4.3-snapshot/rpm/fc30/noarch/ovirt-guest-agent-windows-1.0.16-1.20191009081759.git1048b68.fc30.noarch.rpm

+Try to recover the standby and note down the required `SCN`:

+
+Normaly it should be the same as:
+
+	SQL> select 1+CURRENT_SCN from v$database;

+On primary, identify all datafiles created after this `SCN`; in my example `SCN=5681090`
+
+	SQL> select FILE#,NAME from v$datafile where CREATION_CHANGE# >= 5681090;
+
+Backup datafiles and generate a new standby controlfile:
+
+	run{
+	  set nocfau;
+	  allocate channel ch01 device type disk format '/mnt/yavin4/tmp/_oracle_/orabackup/temp/%d_%U_%s_%t.bck';

+	  backup current controlfile;
+	  release channel ch01;
+	}
+
+
+Restart the standby in mode **NOMOUNT** and restore the standby controfile:

+	RMAN> restore standby controlfile from '/mnt/yavin4/tmp/_oracle_/orabackup/temp/ASTY_0l1678fs_21_1_1_21_1113825788.ctl';
+
+Alternatively, you can restore the standby controfile from active database:
+
+	RMAN> restore standby controlfile from service ASTYPRD_DGMGRL;
+
+Mount the standby database:
+
+	RMAN> alter database mount;
+
+Restore and new datafiles:
+

+
+Catalog recovery area and old standby datafiles:
+
+	RMAN> catalog start with '/data/ASTYDRP' noprompt;
+	RMAN> catalog start with '/fra/ASTYDRP' noprompt;
+
+At this moment, because of fresh restored controlfile, Oracle see the datafiles as datafile copy:
+
+	RMAN> list datafilecopy all;
+
+Switch database to copy:
+
+	RMAN> switch database to copy;
+
+
+To recover standby using *from SCN* backupset, we can proceed from active database or using physical backupset:
+
+	rman auxiliary /
+	run {
+	  allocate channel pri1 device type DISK;
+	  allocate channel pri2 device type DISK;
+	  allocate channel pri3 device type DISK;
+	  allocate channel pri4 device type DISK;
+	  recover database from service ASTYPRD_DGMGRL using compressed backupset section size 8G;
+	}
+
+Clear standby redolog:
+
+	SQL> select 'ALTER DATABASE CLEAR LOGFILE GROUP '||GROUP#||';' from v$standby_log;
+
+Enable **MRP**:
+

+
+
+Dataguard initial duplication
+-----------------------------
+
+From primary init.ora, create an init.ora from secondary database, test-it starting the secondary database in nomount and create a spfile from this init.ora. Startup secondary database in nomount mode. Copy also the passwordfile from primry to secondary server.
+
+Try cross connections from both primary and secondary servers:
+
+	sqlplus 'sys/"*****"'@ASTYPRD_DGMGRL as sysdba
+	sqlplus 'sys/"*****"'@ASTYDRP_DGMGRL as sysdba
+
+
+Create standby redolog on primary database using the result of following queries:
+
+	select 'ALTER DATABASE ADD STANDBY LOGFILE THREAD '||thread#||' size '||bytes||';' from v$log;
+	select distinct 'ALTER DATABASE ADD STANDBY LOGFILE THREAD '||thread#||' size '||bytes||';' from v$log;
+
+If you plan to use backups on standby database, set required RMAN parameters **prior** to duplicate step:
+
+	configure archivelog deletion policy to applied on all standby;
+	configure db_unique_name 'ASTYDRP' connect identifier 'ASTYDRP_DGMGRL';
+	configure db_unique_name 'ASTYPRD' connect identifier 'ASTYPRD_DGMGRL';
+
+
+Duplicate primary database *for standby*:
+
+	rman target='sys/"*****"'@ASTYPRD_DGMGRL auxiliary='sys/"*****"'@ASTYDRP_DGMGRL
+
+	run
+	{
+	  allocate channel pri01 device type disk;
+	  allocate channel pri02 device type disk;
+	  allocate channel pri03 device type disk;
+	  allocate channel pri04 device type disk;
+	  allocate channel pri05 device type disk;
+	  allocate channel pri06 device type disk;
+	  allocate channel pri07 device type disk;
+	  allocate channel pri08 device type disk;
+	  allocate channel pri09 device type disk;
+	  allocate channel pri10 device type disk;
+
+	  allocate auxiliary channel aux01 device type disk;
+	  allocate auxiliary channel aux02 device type disk;
+	  allocate auxiliary channel aux03 device type disk;
+	  allocate auxiliary channel aux04 device type disk;
+	  allocate auxiliary channel aux05 device type disk;
+	  allocate auxiliary channel aux06 device type disk;
+	  allocate auxiliary channel aux07 device type disk;
+	  allocate auxiliary channel aux08 device type disk;
+	  allocate auxiliary channel aux09 device type disk;
+	  allocate auxiliary channel aux10 device type disk;
+
+	  duplicate database 'ASTY' for standby
+	    from active database using compressed backupset section size 512M;
+	}
+
+
+It is nor mandatory but recommanded to activate flashback on both databases (leaving for exmple then default retention target of 1 day):
+
+	alter database flashback ON;
+
+
+Dataguard broker configuration
+------------------------------
+
+On primary database:
+
+	alter system set dg_broker_config_file1='/app/oracle/base/admin/ASTYPRD/dgmgrl/dr1ASTYPRD.dat' scope=both sid='*';
+	alter system set dg_broker_config_file2='/app/oracle/base/admin/ASTYPRD/dgmgrl/dr2ASTYPRD.dat' scope=both sid='*';
+	alter system set dg_broker_start=TRUE scope=both sid='*';
+
+On secondary database:
+
+	alter system set dg_broker_config_file1='/app/oracle/base/admin/ASTYDRP/dgmgrl/dr1ASTYDRP.dat' scope=both sid='*';
+	alter system set dg_broker_config_file2='/app/oracle/base/admin/ASTYDRP/dgmgrl/dr2ASTYDRP.dat' scope=both sid='*';
+	alter system set dg_broker_start=TRUE scope=both sid='*';
+
+On primary or secondary server:
+
+	dgmgrl
+	connect sys/*****@ASTYPRD_DGMGRL
+
+	create configuration ASTY as
+	  primary database is ASTYPRD
+	  connect identifier is ASTYPRD_DGMGRL;
+
+	add database ASTYDRP
+	  as connect identifier is ASTYDRP_DGMGRL
+	  maintained as physical;
+
+	enable configuration;
+
+	edit database 'astyprd' set property ArchiveLagTarget=0;
+	edit database 'astyprd' set property LogArchiveMaxProcesses=2;
+	edit database 'astyprd' set property LogArchiveMinSucceedDest=1;
+	edit database 'astyprd' set property StandbyFileManagement='AUTO';
+
+	edit database 'astydrp' set property ArchiveLagTarget=0;
+	edit database 'astydrp' set property LogArchiveMaxProcesses=2;
+	edit database 'astydrp' set property LogArchiveMinSucceedDest=1;
+	edit database 'astydrp' set property StandbyFileManagement='AUTO';
+
+	edit instance 'ASTYPRD' set property 'StaticConnectIdentifier'='ASTYPRD_DGMGRL';
+	edit instance 'ASTYDRP' set property 'StaticConnectIdentifier'='ASTYPRD_DGMGRL';
+
+	edit instance 'ASTYPRD' set property 'StaticConnectIdentifier'='(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=taris.swgalaxy)(PORT=1523))(CONNECT_DATA=(SERVICE_NAME=ASTYPRD_DGMGRL)(INSTANCE_NAME=ASTYPRD)(SERVER=DEDICATED)))';

+    
+    
+Wait a couple of minutes (after eventually archiving current log on primary database) therefore:
+
+	show configuration
+	show database 'astyprd'
+	show database 'astydrp'
+
+	validate database 'astyprd'
+	validate database 'astydrp'
+
+
+To disable/enable redo apply on standby database:
+
+	edit database 'astydrp' set state='APPLY-OFF';
+	edit database 'astydrp' set state='ONLINE';
+
+
+
+Backup primary and standby databases
+------------------------------------
+
+Backup primary database:
+
+	rman target /
+
+	run
+	{
+	  set nocfau;
+	  allocate channel ch01 device type disk format '/mnt/yavin4/tmp/_oracle_/orabackup/ASTYPRD/%d_%U_%s_%t.bck';

+
+
+Backup standby database:

+> [Original article](https://oracle-base.com/articles/19c/sql-quarantine-19c)
+
+
+
+We can manually quarantine a statement based on SQL_ID or SQL_TEXT.  
+Both methods accept a PLAN_HASH_VALUE parameter, which allows us to quarantine a single execution plan.  
+If this is not specified, all execution plans for the statement are quarantined.
+
+
+	-- Quarantine all execution plans for a SQL_ID.
+	DECLARE
+	  l_sql_quarantine  VARCHAR2(100);
+	BEGIN
+	  l_sql_quarantine := sys.DBMS_SQLQ.create_quarantine_by_sql_id(
+	                        sql_id => 'gs59hr0xtjrf8'
+	                      );
+	  DBMS_OUTPUT.put_line('l_sql_quarantine=' || l_sql_quarantine);
+	END;
+	/
+
+
+SQL quarantine display:
+
+	set lines 256
+	COLUMN sql_text FORMAT A50 TRUNC
+	COLUMN plan_hash_value FORMAT 999999999999
+	COLUMN name FORMAT A30
+	COLUMN enabled FORMAT A3 HEAD "Ena"
+	COLUMN cpu_time FORMAT A10
+	COLUMN io_megabytes FORMAT A10
+	COLUMN io_requests FORMAT A10
+	COLUMN elapsed_time FORMAT A10

+
+	select 
+		name, enabled,cpu_time, io_megabytes, io_requests, elapsed_time, io_logical, plan_hash_value, sql_text
+	from 
+		dba_sql_quarantine;
+
+
+The ALTER_QUARANTINE procedure allows us to alter the thresholds, to make them look more like automatically generated quarantines.  
+We can use the procedure to alter the following parameters:
+
+- CPU_TIME
+- ELAPSED_TIME
+- IO_MEGABYTES
+- IO_REQUESTS
+- IO_LOGICAL
+- ENABLED
+- AUTOPURGE
+
+Example of setting the CPU_TIME threshold for the manually created quarantines:
+
+	BEGIN
+	  DBMS_SQLQ.alter_quarantine(
+	    quarantine_name  =>  'SQL_QUARANTINE_8zpc9pwdmb8vr',
+	    parameter_name   =>  'CPU_TIME',
+	    parameter_value  =>  '1');
+	 END;

+2. unplug the PDB from auxiliary CDB and plug it on target PDB
+
+
+> A *set until time* clause can be specified in duplicate command.
+
+Start AUXCDB CDB instance using a basic spfile, therefore run the duplicate command:
