Database Recovery with RMAN backup (Disaster Recovery)

Database Recovery with RMAN backup (Disaster Recovery)
This are the steps for Database recovery when entire complete database crashed even though don’t have spfile and control file backup. I have one copy of Full RMAN backup. Using this backup I am going to be performing the recovery scenario.
Here in this case required to rebuild entire database server
Environment is  OEL 6.5 Oracle 11g with ASM standalone server.
RMAN Backup:
1)      Controlfile and SPFILE autobackup
2)      RMAN Full Backup files
3)      RMAN Archivelog files
Steps:
1)      Create new file system same as old server.
2)      Install same version of Oracle Software in the production server.(In this case 11.2.0.3 Enterprise Edition).
3)      Create the Instance.
4)      Create the relevant folder hierarchy under <ORACLE_BASE> directory.
5)      Restore the SPFILE from autobackup, and use the SPFILE to start the instance in NOMOUNT state.
6)      Restore the controlfile from autobackup, and MOUNT the database .
7)      Restore the Database from RMAN backup files .
8)      Recover the Database from RMAN backup files, and OPEN the database with RESETLOGS.



Database Disaster Recovery using only RMAN Backups
Note: After installation of same version of Oracle software below are the steps to be followed.

ORA-12516: TNS:LISTENER COULD NOT FIND AVAILABLE HANDLER WITH MATCHING PROTOCOL STACK

Dear Friends,

Below are steps for ORA-12516: TNS:LISTENER COULD NOT FIND AVAILABLE HANDLER WITH MATCHING PROTOCOL STACK error

ERROR : ORA-12516: TNS:listener could not find available handler with matching protocol stack

CAUSE :
 Its Reached maximum process.

SOLUTION : 

Check maximum value for processes and sessions

select name, value from v$parameter where name in (‘processes’,’sessions’);

Check current process and session and maximum limitation

select * from v$resource_limit;

Increase your process and session, for example to 800

alter system set processes=800 scope=spfile;
alter system set sessions=885 scope=spfile;

Restart the Database with below commands,

shutdown immediate;

and 

startup;

or 

startup force ;

all changes will effected permanently.
