How to change/Modify SCAN Listener port in oracle RAC


 CHANGE  SCAN LISTENER PORT IN RAC DATABASE
================================================

Step 1:- verify current status and port of scan listener 

[grid@rac1 ~]$ srvctl config scan_listener
SCAN Listener LISTENER_SCAN1 exists. Port: TCP:1521
SCAN Listener LISTENER_SCAN2 exists. Port: TCP:1521
SCAN Listener LISTENER_SCAN3 exists. Port: TCP:1521
[grid@rac1 ~]$
[grid@rac1 ~]$
[grid@rac1 ~]$ srvctl status scan
SCAN VIP scan1 is enabled
SCAN VIP scan1 is running on node rac2
SCAN VIP scan2 is enabled
SCAN VIP scan2 is running on node rac1
SCAN VIP scan3 is enabled
SCAN VIP scan3 is running on node rac1
[grid@rac1 ~]$



Step 2:-  Change port number of the SCAN LISTENER

[grid@rac1 ~]$ srvctl modify scan_listener -p 1585
[grid@rac1 ~]$
[grid@rac1 ~]$ srvctl config scan_listener
SCAN Listener LISTENER_SCAN1 exists. Port: TCP:1585
SCAN Listener LISTENER_SCAN2 exists. Port: TCP:1585
SCAN Listener LISTENER_SCAN3 exists. Port: TCP:1585
[grid@rac1 ~]$

Step 3:- Restart SCAN LISTENER using below command 

[grid@rac1 ~]$ srvctl stop scan_listener
[grid@rac1 ~]$
[grid@rac1 ~]$ srvctl start scan_listener
[grid@rac1 ~]$
[grid@rac1 ~]$ srvctl status scan
SCAN VIP scan1 is enabled
SCAN VIP scan1 is running on node rac2
SCAN VIP scan2 is enabled
SCAN VIP scan2 is running on node rac1
SCAN VIP scan3 is enabled
SCAN VIP scan3 is running on node rac1
[grid@rac1 ~]$
[grid@rac1 ~]$ srvctl config scan_listener
SCAN Listener LISTENER_SCAN1 exists. Port: TCP:1585
SCAN Listener LISTENER_SCAN2 exists. Port: TCP:1585
SCAN Listener LISTENER_SCAN3 exists. Port: TCP:1585
[grid@rac1 ~]$
[grid@rac1 ~]$
[grid@rac1 ~]$
[grid@rac1 ~]$
[grid@rac1 ~]$
[grid@rac1 ~]$ srvctl config scan_listener
SCAN Listener LISTENER_SCAN1 exists. Port: TCP:1585
SCAN Listener LISTENER_SCAN2 exists. Port: TCP:1585
SCAN Listener LISTENER_SCAN3 exists. Port: TCP:1585
[grid@rac1 ~]$
[grid@rac1 ~]$

Step 4:- Modify remote_listener parameter in each rac instance  also change port number in  tns entries

Before database stop change 

alter system set remote_listener='rac-scan:1585' scope=both sid='*';

Bounce database
[grid@rac1 ~]$ srvctl stop database -d orcl
[grid@rac1 ~]$
[grid@rac1 ~]$ srvctl start database -d orcl
[grid@rac1 ~]$
[grid@rac1 ~]$
[grid@rac1 ~]$ srvctl status database -d orcl
Instance orcl1 is running on node rac1
Instance orcl2 is running on node rac2
[grid@rac1 ~]$
[grid@rac1 ~]$ lsnrctl status LISTENER_SCAN2

Relocate Voting disk to +DATA1 to different disks



Step1: Verify voting disk location using below command 

[root@rac1 bin]#
[root@rac1 bin]#
[root@rac1 bin]# ./crsctl   query css votedisk
##  STATE    File Universal Id                File Name Disk group
--  -----    -----------------                --------- ---------
 1. ONLINE   10ee09a0a8a44fe5bf6184e1f3abdc06 (ORCL:DISK1) [DATA1]
Located 1 voting disk(s).
[root@rac1 bin]#
[root@rac1 bin]#


Step2:-  Now move voting disk  to +DATA2 using below command 

[root@rac1 bin]# ./crsctl  replace votedisk +DATA2
Successful addition of voting disk 2edb42aeb93d4fa7bfd06327ae391776.
Successful deletion of voting disk 10ee09a0a8a44fe5bf6184e1f3abdc06.
Successfully replaced voting disk group with +DATA2.
CRS-4266: Voting file(s) successfully replaced
[root@rac1 bin]#
[root@rac1 bin]#

Step3:- verify voting disk location

[root@rac1 bin]# ./crsctl   query css votedisk
##  STATE    File Universal Id                File Name Disk group
--  -----    -----------------                --------- ---------
 1. ONLINE   2edb42aeb93d4fa7bfd06327ae391776 (ORCL:DISK2) [DATA2]
Located 1 voting disk(s).
[root@rac1 bin]#


Note : make sure asm_diskstring configure properly  before relocation

Relocate OCR from +DATA1 to different disks


Task:-
 Relocate OCR from +DATA1 to +DATA2

Requirement:-

Need +DATA2 disk group 


Step 1: Check current OCR location 


[root@rac1 bin]# ./ocrcheck

How to Restore database using Cold Backup in Noarchivelog Mode Without Online Redo Logs

Restoring a Cold Backup in Noarchivelog Mode Without Online Redo Logs
====================================================================

1. Shut down the instance.
2. Copy the control files and data files back from the backup.
3. Start up the database in mount mode.
4. Open the database with the OPEN RESETLOGS clause.



Step 1. Shut Down the Instance
--------------------------------------------------------------------------------------


$ sqlplus / as sysdba
SQL> shutdown abort;


Step 2. Copy the Files Back(datafiles and controlfiles) from the Backup without redo logfiles backup
----------------------------------------------------------------------------------------------------

$ cp <backup directory>/*.* < database file directory>


Step 3. Start Up the Database in Mount Mode
----------------------------------------------------------------------------------------------------

$ sqlplus / as sysdba
SQL> startup mount



Step 4. Open the Database with the OPEN RESETLOGS Clause
--------------------------------------------------------------------------------------------------

SQL> alter database open resetlogs;

you will get error


ORA-01139: RESETLOGS option only valid after an incomplete database recovery


{SQL> alter database open resetlogs;
alter database open resetlogs
*
ERROR at line 1:
ORA-01139: RESETLOGS option only valid after an incomplete database recovery}


SQL>


SQL> recover database;
ORA-00283: recovery session canceled due to errors
ORA-00264: no recovery required


SQL> alter database open resetlogs;
alter database open resetlogs
*
ERROR at line 1:
ORA-01139: RESETLOGS option only valid after an incomplete database recovery


SQL> recover database until cancel;
Media recovery complete.
SQL>

SQL> alter database open;
alter database open
*
ERROR at line 1:
ORA-01589: must use RESETLOGS or NORESETLOGS option for database open


SQL>


Now, attempt to open your database with the OPEN RESETLOGS clause:
SQL> alter database open resetlogs;



==========================================
>>> Error you will get:-
==========================================


SQL> startup
