prvf 5300 failed to retrieve active version for crs on this node

We tried to install  11.2.0.2 oracle software version.When we ran the runInstaller it throws the
 prvf 5300 failed to retrieve active version for crs on this node error.
 11.2.0.3 ASM Grid already installed in server also the server has 11.1.0.7 version software and 11.1.0.7 databases using 11.2.0.3 ASM

Solution:-

1. Backup the files /etc/ocr.loc or /etc/oracle/ocr.loc and /etc/oracle/olr.loc, then rename them to some other names.
2. Retry the standalone (non-RAC) Database 11.2.0.2 installation.
3. After installation completed; restore/rename the backed up files to ocr.loc and olr.loc files in the /etc/ocr.loc or /etc/oracle/ocr.loc and /etc/oracle/olr.loc

Note:-
--No need to shutdown the existing databases and ASM while performing this operations.
--In some environment ocr.loc file is located in  /etc/ocr.loc or /etc/oracle/ocr.loc. It depends on the Operating System.

Problem we have faced at our environment:-


After renamed both the files we are unable to log in to existing databases available in that server.
We have not restored the original files ocr.loc and olr.loc files in original location after completing 11.2.0.2 oracle software installation ,so we have faced the below error;  
Note:- We came to know ; These 2 files are needed if we are using a grid,.
after renamed both the files to original name; we are able to log in to existing databases available in that server.

see the below error message:-
SQL> select status from v$datafile;
select status from v$datafile
*
ERROR at line 1:
ORA-00204: error in reading (block 1, # blocks 1) of control file
ORA-00202: control file: '+DG1/eagleb/controlfile/current.716.751453263'
ORA-15081: failed to submit an I/O operation to a disk

we have renamed the files ocr.loc and olr.loc again from backup. and the problem got resolved.
   
These 2 files are needed if we are using a grid,.

I really thank my colleague Krishna; We worked together in this problem.

Drop Database Command Demo

From 10g onwards, we have Drop Database command, that made a fast and efficient cleanup of all datafiles, redologs and control files in one command.


Drop database do require to mount the database in exclusive restricted mode.

The steps are as follows:

•shutdown abort;

•startup mount exclusive restrict;

•drop database;

Here is a Demo:-

Step by Step document to Create Physical Standby Database from Active Database using RMAN

Step by step document to create a physical standby database using RMAN DUPLICATE FROM ACTIVE DATABASE command without shutting down the primary and using primary active database files (No need to take backup)

Database Name :- WHITE
Primary db_unique_name :- WHITE
standby db_unique_name :- BLACK

Primary Database Server Name :- DC1
Standby Database Server Name :- DC2

Steps:-
1.Make the necessary changes to the primary database.
a. Enable force logging.
b. Creating the password file if one does not exist.
c. Create standby redologs.
d. Modify the parameter file suitable for Dataguard.
e. Change the database to archivelog mode if it is in no archivelog mode.
2. Ensure that the sql*net connectivity is working fine.
----if not add an entry for database in TNSNAMES.ORA and LISTENER.ORA file for primary and standby database.
3. Create the standby database over the network using the active(primary) database files.

a.create a password file for standby database
The username is required to be SYS and the password needs to be the same on the Primary and Standby.
The password file name must match the instance name/SID used at the standby site, not the DB_NAME.
b. Create the initialization parameter file for the standby database (auxiliary database)
c. Create the necessary mount points or the folders for the database files
d. Run the standby creation ON STANDBY by connecting to primary as target database.

      RMAN> run {
allocate channel prmy1 type disk;
allocate channel prmy2 type disk;
allocate channel prmy3 type disk;
allocate channel prmy4 type disk;
allocate auxiliary channel stby type disk;

}

4. Check the log shipping and apply.

Create single instance standby database for RAC Database

here i created a physical standby database stbydb for RAC database primdb instance names primdb1 and primdb2 , server names:- DC1 and DC2.

PRIMARY RAC DATABASE INSTANCE PRIMDB1 IN HOST MACHINE DC1
PRIMARY RAC DATABASE INSTANCE PRIMDB2 IN HOST MACHINE DC2

CREATING A STANDBY DATABASE IN SERVER DC2 WITH NAME STBYDB

ASSUMPTION:
Primary:

· The RAC Primary Database is in fully operating condition in Archivelog mode using ASM storage (shared location) as archivelog destination.
· The Primary Database is using ASM as Storage and OMFs.
· Listener LISTENER has already been created.

steps in primary database Servers:-
# Database must in Archivelog mode.
# Enable Force Logging.
# Create the Standby Redo logs.
# Create a password file for all instances( Password must same in all nodes).
# Update listener.ora file to include SID information on each node in cluster.
# Verify cluster Service is available.
# Verify TNSNAMES.ORA file.
# Modify init.ora Parameters For DataGuard Configuration.
# Create temporary directory to hold the RMAN backup of this database.
# Backup the Primary Database for Standby.
# copy the Primary Database backup to the standby database server to create standby database.

steps in Standby database server:-
# create required folders and directories.
# Modify the init.ora parameter on standby database.
# create a password file(Password must same as primary database instances)
# Update listener.ora file to include SID information
# Add required TNS entries for standby database on all servers.
# Verify TNSNAMES.ORA file.
# Create standby database.

Steps to Rename RAC instance name

Steps to Rename RAC instance name

In this demo, The RAC database name:- RACDB
I have renamed the database instance racdb1 to rac1db (HOSTNAME DC1)
and instance racdb2 to rac2db (HOSTNAME DC2)
1. take a backup of the initracdb1.ora and initracdb2.ora files.

[oracle@dc1 dbs]$ cp initracdb1.ora initracdb1.ora_bkp
[oracle@dc1 dbs]$ cat initracdb1.ora
SPFILE='+DATA/proddb/spfileracdb.ora'

2. create a new pfile from spfile

SQL> show parameter spfile

NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
spfile                               string      +DATA/proddb/spfileracdb.ora

[oracle@dc1 dbs]$ 
[oracle@dc2 ~]$ orapwd file=$ORACLE_HOME/dbs/orapwrac2db password=oracle

6.Add an entry in the /etc/oratab file on all the nodes
example:-
on host machine DC1
vi /etc/oratab
rac1db:/u01/app/oracle/product/11.2.0/db_1:N
on host machine DC2
vi /etc/oratab
rac2db:/u01/app/oracle/product/11.2.0/db_1:N

7.Startup the database with new init.ora file and create a spfile using new pfile.

[oracle@dc1 dbs]$ . oraenv
ORACLE_SID = [rac2db] ? rac1db
[oracle@dc1 dbs]$ sqlplus / as sysdba

9.remove the old instance name and add a new instance name using srvctl command.

[oracle@dc2 dbs]$ srvctl remove instance -i racdb1 -d racdb 
Remove instance from the database racdb? (y/[n]) y
[oracle@dc2 dbs]$ srvctl remove instance -i racdb2 -d racdb
Remove instance from the database racdb? (y/[n]) y

[oracle@dc2 dbs]$ srvctl add instance -i rac1db -d racdb -n dc1
[oracle@dc2 dbs]$ srvctl add instance -i rac2db -d racdb -n dc2
[oracle@dc2 dbs]$ srvctl start database -d racdb

10.Verify it.

Rename RAC Database

Here is the document to rename RAC database and next post we can see how to rename rac instance.

here is an example.

renamed RAC database proddb to racdb in servers dc1 and dc2.

SQL> select instance_name,host_name from gv$instance;

INSTANCE_NAME    HOST_NAME
---------------- -------------------------
proddb1          dc1.localdomain
proddb2          dc2.localdomain

SQL> select name from v$database;

NAME
---------
PRODDB

taken backup of pfile initproddb1.ora and initproddb2.ora on both nodes.

[oracle@dc1 dbs]$ cat initproddb1.ora
SPFILE='+DATA/proddb/spfileproddb.ora'
[oracle@dc1 dbs]$ cp initproddb1.ora initproddb1.ora_orig 
[oracle@dc1 dbs]$ 

[oracle@dc2 ~]$ cd $ORACLE_HOME/dbs
[oracle@dc2 dbs]$ cat initproddb2.ora 
SPFILE='+DATA/proddb/spfileproddb.ora'
[oracle@dc2 dbs]$ cp initproddb2.ora initproddb2.ora_bkp
[oracle@dc2 dbs]$ 

create pfile from spfile.
taken controlfile backup to rename rac database.

SQL> create pfile='/tmp/initproddb1.ora' from spfile;

File created.

SQL> alter database backup controlfile to trace;

Database altered.

SQL> --- or ----
SQL> 
SQL> alter database backup controlfile to trace as '/tmp/ctl_trc_bkp.txt';

Database altered.

stop the RAC database using srvctl command.

[oracle@dc1 ~]$ srvctl status database -d proddb
Instance proddb1 is running on node dc1
Instance proddb2 is running on node dc2
[oracle@dc1 ~]$ srvctl config database -d proddb
Database unique name: proddb
