Database Software

Hello all, this will be my first post to the support forum. I'm an associate dba with just 6 months on the job, so if I've forgotten something or not given some infromation that is needed please let me know.

I've also combed the forums/internet, and some of the answers haven't helped. The Oracle Document ORA-1103 While Mounting the Database Using PFILE [ID 237073.1] says my init.ora file is corrupted, but creating a new init.ora file from the spfile does not help. Neither does just starting from the spfile. I have older copies of the init.ora file and the spfiles that the database was running on previously, so I believe they are good.

This standby NIRNASD1 has existed previously, I had to refresh the primary NIKNASD2, and then re-instantiate NIRNASD1 after the refresh is complete.

My env is set correctly, and my ORACLE_SID has been exported to NIRNASD1
NIKNASD2 = Primary Database
NIRNASD1 = Secondary/Standby Database
Goal: Creation of Logical Standby NIRNASD1 after creating Physical Standby from NIKNASD2
My database versions are 10.2.0.4.0, and the databases are on a Unix server. Both databases are located on separate servers.


Steps that I have taken:

I used RMAN to backup our primary database to the staging area:
$ rman target /

run {
backup database
format '/datatransa/dg_stage/%U'
include current controlfile for standby;
sql "alter system archive log current";
backup archivelog all format '/datatransa/dg_stage/%U';
}

I used RMAN to Create Secondary Database utilizing RMAN DUPLICATE command.

RMAN> run {
2> allocate auxiliary channel auxdisk device type disk;
3> duplicate target database for standby NOFILENAMECHECK;
4> }


On Secondary database I started Managed Recovery mode

SQL> shutdown immediate;
ORA-01109: database not open

Database dismounted.
ORACLE instance shut down.

(I used pfile here, thinking that I needed to mount the database to the pfile so that the database would see the change in the dataguard parameters in the init.ora file, the change from logical to physical- I commeneted out the logical and uncommented the physical line)

###########################################
# Dataguard Parameters

For logical standby, change db_name to name of standby database.

#db_name=NIRNASD1 ### for logical, db_name is same as unique_name


SQL> STARTUP MOUNT PFILE = /oraa/app/oracle/product/1020/admin/NIRNASD1/pfile/initNIRNASD1.ora;

SQL> ALTER DATABASE recover managed standby database using current logfile disconnect;

I then verified the Data Guard Configuration by using “alter system archive log current;” on the primary database and watching the sequence number change in the secondary database.

I made sure that:
• The primary database was in MAXIMUM PERFORMANCE MODE
• Stopped managed recover on the standby database: alter database recover managed standby database cancel;
• Built a logical standby data dictionary on the primary database
• The db_name in init.ora was changed (this is in our document at my job)
• I changed my database name (from physical to logical) in my init.ora pfile (reverse of what I did above)

###########################################
# Dataguard Parameters
###########################################
For logical standby, change db_name to name of standby database.
#db_name=NIKNASD2 ### for physical, db_name is same as primary
db_name=NIRNASD1 ### for logical, db_name is same as unique_name

I then went to shutdown my standby database and re-start it in a mount exclusive state, which is where I get the ORA-01103 Error (Again I used the pfile, thinking that I needed to tell the database it is now a logical standby):
SQL> shutdown immediate;
ORA-01109: database not open
Database dismounted.
ORACLE instance shut down.


SQL> STARTUP EXCLUSIVE MOUNT PFILE = /oraa/app/oracle/product/1020/admin/NIRNASD1/pfile/initNIRNASD1.ora;

ORA-01103: database name 'NIKNASD2' in control file is not 'NIRNASD1'

From what I understand of the process, the name in the control file is correct, I want it to be NIRNASD1. But the database for some reason thinks it should be NIKNASD2. The following are the parts of my init.ora file that include the dataguard parameters:

I would appreciate any help, or pointing me in the right direction. I'm just missing something. I am reviewing the documents for building a physical and logical standby from oracle. Just not sure where to go from here.

Thank you
