RMAN Active Duplicate on RAC fails with ORA-17629 and ORA-17627: ORA-12154

RMAN active duplication of RAC database fails on restart operation with the following error messages:

ORA-17627: ORA-12154: TNS:could not resolve the connect identifier specified
ORA-17629: Cannot connect to the remote database server

RMAN> exit

Reason:


ORA-12154 is raised whenever the TNS alias is not found on tnsnames.ora

After verification of tnsanames.ora files from both installations on Target and Auxiliary we see all the proper entries are there Still the RMAN duplicate command fails on ORA-12154

The reason for ORA-12154 being raised is because the process is looking for tnsnames.ora in a different ORACLE_HOME on the Auxiliary side.   This different ORACLE_HOME on Auxiliary side is usually the GRID HOME.

On 11G RAC Customers can configure SCAN Listener to handle failover connections on DB and ASM instances.

When RMAN duplicate is executed it needs to shutdown/startup the database several times.  Once the DB is down, a TNS connection can get lost on next startup since the corresponding service associated with the instance is no longer available.  The connection from RMAN thus fails when looking for the tnsnames.ora file under the wrong home.

Resolution:

There are two ways to workaround this problem

1) Copy the tnsnames.ora file form the RDBMS Home to the GRID Home

2) Establish a direct connection instead of using a TNS alias.  For example:

RMAN> connect auxiliary sys/pwd@(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=myauxiliaryhost)(PORT=1521))(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=QRM)(UR=A)))

For Example:

oracle@said$ rman target sys@orcl

Resize Redo Log size in Data Guard ( Primary and Standby) Oracle 11g


-----------Resize Redo Log in Primary Database-------

alter database drop logfile group 2;
alter database add logfile  group 2 '/u01/app/oracle/oradata/orcl/redo02.log' size 5m;

alter database drop logfile group 3;
alter database add logfile  group 3 '/u01/app/oracle/oradata/orcl/redo03.log' size 5m;

alter system switch logfile

alter database drop logfile group 1;

--Error Come----

ORA-01624: log 1 needed for crash recovery of instance orcl (thread 1)
ORA-00312: online log 1 thread 1: '/u01/app/oracle/oradata/orcl/redo01.log'

select group#,status from v$log;

alter system checkpoint;

alter database drop logfile group 1;

alter database add logfile  group 1 '/u01/app/oracle/oradata/orcl/redo01.log' size 5m;


alter database drop logfile group 4;

ALTER DATABASE ADD STANDBY LOGFILE GROUP 4 '/u01/app/oracle/oradata/orcl/stby04.log' size 5m;

alter database drop logfile group 5;

ALTER DATABASE ADD STANDBY LOGFILE GROUP 5 '/u01/app/oracle/oradata/orcl/stby05.log' size 5m;

alter database drop logfile group 6;

ALTER DATABASE ADD STANDBY LOGFILE GROUP 6 '/u01/app/oracle/oradata/orcl/stby06.log' size 5m;

-----------Resize Redo Log in Standby Database-------

Check Database Status

SQL> select status,instance_name,database_role from v$database,v$Instance;

STATUS       INSTANCE_NAME    DATABASE_ROLE
------------ ---------------- ----------------
OPEN         orcls         PHYSICAL STANDBY

SQL>

Check if the parameter standby_file_management is set to AUTO or MANUAL on standby database. If it is not set to MANUAL, then set it.

         3 CURRENT

SQL> alter database drop logfile group 1;
alter database drop logfile group 1
*
ERROR at line 1:
ORA-01156: recovery or flashback in progress may need access to files

Now to solve this issue we have cancel the managed recovery session
and set  "standby_file_management"  to manual and drop the standby redolog file  as

SQL> alter database recover managed standby database cancel ;

Database altered.

SQL>
SQL> alter database drop logfile group 1;
alter database drop logfile group 1

SQL> select group#,status from v$log;

    GROUP# STATUS
---------- ----------------
         1 CLEARING
         2 CLEARING
         3 CURRENT


If the status of standby redolog show the "clearing_current" then we cannot drop "clearing_current" status
logs,and for that we have to sync with Primary and clear the log first before dropping as

SQL> alter database clear logfile group 1;

SQL> select group#,status from v$log;

    GROUP# STATUS
---------- ----------------
         1 UNUSED
         2 CLEARING
         3 CURRENT

SQL>  alter database drop logfile group 1;

Database altered.

SQL> alter database add logfile  group 1 '/u01/app/oracle/oradata/orcls/redo01.log' size 5m;

Database altered.

SQL> alter database clear logfile group 2;

Database altered.

SQL>  alter database drop logfile group 2;

Database altered.

SQL> alter database add logfile  group 3 '/u01/app/oracle/oradata/orcls/redo03.log' size 5m;

---Now Remove Standby Redolog file---

SQL> select group#,status from v$standby_log;

    GROUP# STATUS
---------- ----------

SQL> alter database drop standby logfile group 6;

SQL> ALTER DATABASE ADD STANDBY LOGFILE GROUP 6 '/u01/app/oracle/oradata/orcls/stby06.log' size 5m;

----Now check the status of red log and standby redo log status----

SQL> select group#,status from v$standby_log;

    GROUP# STATUS
---------- ----------
         4 UNASSIGNED
         5 UNASSIGNED
         6 UNASSIGNED

SQL> select group#,status from v$log;

Once all the Standby Redo Logs and Online Redo Logs have been resize on both Primary and standby database,
set the STANDBY_FILE_MANAGEMENT to AUTO on the standby database and start the recovery (MRP) on standby database.

SQL> alter system set standby_file_management=auto;

The Data Guard status of is Error ORA-19502: write error on file "", block number (block size=).

Error:  The Data Guard status of STLBAST is Error ORA-19502: write error on file "", block number (block size=).

Reason: Archive Destination become full in Standby Database server location.

Solution:

Step1: Check alert log both primary and standby database server.





Step2: Check Data Guard status log in primary Database server using following query


2015-DEC-01 09:58:18   ARC8: Completed archiving thread 1 sequence 57395 (10616070471665-10616070713099)

Step3: Login to Standby Database server and check the maximum archive log sequence that have already applied in Standby Database using following query

SELECT max(sequence#) AS "STANDBY", applied
FROM v$archived_log GROUP BY applied; 

or

SELECT THREAD#, SEQUENCE#, APPLIED
FROM V$ARCHIVED_LOG;

1 57405 YES
1 57404 YES
1 57403 YES
1 57402 YES
1 57401 YES
1 57400 YES

Step4: Purge old archive log that already applied in standby Database. Now check alert log in both primary and standby Database servers.

Step by step to configure Oracle DataGuard in Oracle 10g

Step by step to configure Oracle DataGuard in Oracle 10g

The Enviroment 

2 Linux servers, Oracle Distribution 2.6.9-55 EL i686 i386 GNU/Linux
Oracle Database 10g Enterprise Edition Release 10.2.0.1.0
ssh is configured for user oracle on both nodes
Oracle Home is on identical path on both nodes

Implementation notes: 

Once you have your primary database up and running these are the steps to follow:

1.  Enable Forced Logging
2.  Create a Password File
3.  Configure a Standby Redo Log
4.  Enable Archiving
5.  Set Primary Database Initialization Parameters

Having followed these steps to implement the Physical Standby you need to follow these steps:

1.  Create a Control File for the Standby Database
2.  Backup the Primary Database and transfer a copy to the Standby node.
3.  Prepare an Initialization Parameter File for the Standby Database
4.  Configure the listener and tnsnames to support the database on both nodes
5.  Set Up the Environment to Support the Standby Database on the standby node.
6.  Start the Physical Standby Database
7.  Verify the Physical Standby Database Is Performing Properly


Step by Step Implementation of a Physical Standby Environment

------------------------------------ ----------- ------------------------------
db_unique_name                       string      whiteowl

Enable Forced Logging

In order to implement Standby Database we enable 'Forced Logging'.

This option ensures that even in the event that a 'nologging' operation is done, force logging takes precedence and all operations are logged
into the redo logs.

SQL> ALTER DATABASE FORCE LOGGING;

Database altered.  

Create a Password File

A password file must be created on the Primary and copied over to the Standby site. The sys password must be identical on both sites. This is
a key pre requisite in order to be able to ship and apply archived logs from Primary to Standby.

cd $ORACLE_HOME/dbs
[vmractest1] > orapwd file=orapwwhiteowl password=oracle force=y

Configure a Standby Redo Log

A Standby Redo log is added to enable Data Guard Maximum Availability and Maximum Protection modes. It is important to configure the
Standby Redo Logs (SRL) with the same size as the online redo logs.
In this example I'm using Oracle Managed Files, that's why I don't need to provide the SRL path and file name. If you are not using OMF's
you then must pass the full qualified name.

Data Guard must use spfile, in order to configure it we create and configure the standby parameters on a regular pfile, and once it is ready we
convert it to an spfile.
Several init.ora parameters control the behavior of a Data Guard environment. In this example the Primary database init.ora is configured so
that it can hold both roles, as Primary or Standby.

SQL> create pfile='/oradisk/app01/oracle/product/10gDB/dbs/pfilewhiteowl.ora'  from spfile;

File created.

Edit the pfile to add the standby parameters, here shown highlighted:

Reason:

Adding a Tablespace / Datafile in Primary Database causes the MRP in Physical Standby Database to terminate with the Error below. STANDBY_FILE_MANAGEMENT = MANUAL is set on the Standby Database.

Solution:

Following steps need to perform in Standby Database

Step 1: Ensure the standby_file_management = 'MANUAL' 

Step 2: Identify the File which is "unnamedn" in standby
SQL> select name from v$datafile;

Step 3: Rename/create the Datafile to the correct Filename

alter database create datafile '/u01/app/oracle/product/11.2.0/dbhome_1/dbs/UNNAMED00059' as '/idx01/oradata/orclt/orbind02.dbf';

Step 4: Verify the Filename is correct

SQL> select name from v$datafile;

Step 5: Change the STANDBY_FILE_MANAGMENT to AUTO

ALTER SYSTEM SET STANDBY_FILE_MANAGEMENT=AUTO scope=both;

Step 6: Start the MRP (this is using Real Time Apply)

alter database recover managed standby database using current logfile disconnect;


Step 7: Verify the MRP is running as expected

MRP0: Background Media Recovery process shutdown (STLBAST)

Symptoms

Adding a Tablespace / Datafile in Primary Database causes the MRP in Physical Standby Database to terminate with the Error below. STANDBY_FILE_MANAGEMENT = MANUAL is set on the Standby Database.
MRP0: Background Media Recovery terminated with error 1274
ORA-01274: cannot add datafile '...dbf' - file could not be created

In Unix Environment you will get the below Message when try to restart the MRP

ORA-01111: name for data file 163 is unknown - rename to correct file

Cause


This Error occurs if we add a Datafile OR Tablespace in PRIMARY Database and that could not be translated to the Standby Database due to these Reasons:

  • Standy_file_management is set to MANUAL
  • Primary & Physical Standby are having different file structures and DB_FILE_NAME_CONVERT is not set according to the Directory Structures in Primary and Standby
  • Insufficient Space or wrong Permissions on the Standby Database to create the Datafile

The Redo Log generated from Primary will have Information about the Tablespace / Datafile added however it could not be created successfully in Physical Standby Database due to the standby_file_management = MANUAL
or is not able to find the specified Folder due to a missing / incorrect Filename Conversion.
The File Entry is added to Standby Controlfile as "UNNAMED0000n" in /dbs or /database
folder depends on the Operating System and eventually the MRP terminates.
Alert Log in Standby Shows MRP is terminated with below error
=================================================================
File #5 added to control file as 'UNNAMED00005' because
the parameter STANDBY_FILE_MANAGEMENT is set to MANUAL
The file should be manually created to continue.

ORA-01274: cannot add datafile 'D:\ORADATA\PRIM\SALES01.DBF' - file could not be created



By default it is AUTO by broker.

Solution

Perform all mentioned Steps on the Standby Database:

Step 1: Ensure the standby_file_management = 'MANUAL'

NOTE : For the parameter db_file_name_convert change if the Data Guard Broker is enabled then edit the Parameters using the Broker,
DGMGRL>edit database '' set property DbFileNameConvert='<>','<>';
DGMGRL>edit database '' set property StandbyFileManagement=manual;

By default StandbyFileManagement is AUTO by broker.

Step 2: Identify the File which is "unnamedn"
SQL> select name from v$datafile;

NAME
--------------------------------------------------------------------------------
D:\ORADATA\MYSTD\SYSTEM.DBF
D:\ORADATA\MYSTD\UNDO.DBF
D:\ORADATA\MYSTD\SYSAUX.DBF
D:\ORADATA\MYSTD\SERVICE01.DBF
C:\ORACLE\PRODUCT\10.2.0\DB_1\DATABASE\UNNAMED00005



Step 3: Rename/create the Datafile to the correct Filename
SQL> alter database create datafile 'C:\ORACLE\PRODUCT\10.2.0\DB_1\DATABASE\UNNAMED00005' as 'D:\oradata\mystd\sales01.dbf';

If the standby is in ASM + OMF then use the below command,
SQL> alter database create datafile '/oracle/product/GSIPRDGB/dbs/UNNAMED00210' as <'+ASMDISKGROUPNAME'> size ;

or
SQL>alter database create datafile '/oracle/product/GSIPRDGB/dbs/UNNAMED00210' as new;


Step 4: Verify the Filename is correct
SQL> select name from v$datafile;

NAME
--------------------------------------------------------------------------------
D:\ORADATA\MYSTD\SYSTEM.DBF
D:\ORADATA\MYSTD\UNDO.DBF
D:\ORADATA\MYSTD\SYSAUX.DBF
D:\ORADATA\MYSTD\SERVICE01.DBF
D:\ORADATA\MYSTD\SALES01.DBF


Step 5: Change the STANDBY_FILE_MANAGMENT to AUTO
SQL> ALTER SYSTEM SET STANDBY_FILE_MANAGEMENT=AUTO scope=both;


Step 6: Start the MRP (this is using Real Time Apply)
SQL> alter database recover managed standby database using current logfile disconnect;


Database altered.


Step 7: Verify the MRP is running as expected

Cause

ORA-600[2619] is raised due to an invalid next_change# detected in archive log.

In this case, it is caused by the archive log disk space ran out on standby site, causing that archive log not fully written on disk. This lead to ORA-600[2619] when the archive log was applied.

Per standby alert log:

Solution

1. Clear the disk space where archive log stored on standby site

2. Copy the problem archive log (eg: 1_28158_842022897.arc) from the primary site and replace the one on the standby, then restart Managed Recovery.

Archive log should be applied properly now

PATH=$ORACLE_HOME/bin:$PATH; export PATH
LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib; export LD_LIBRARY_PATH
CLASSPATH=$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib; export CLASSPATH
Step 3: Create folder (Data files, control files, Redo logs and dump files) similar to Primary Database.
Step 4: Create Listener and tns in Standby Database and modify the tns Primary Database.
tnsnames.ora at Primary Database
sbs =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.6.1.74)(PORT = 1522))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = sbs)
)
)
sbsdr =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.6.1.73)(PORT = 1522))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = sbs)
)
)
listener.ora file at standby side
SID_LIST_LISTENER_SBSDR =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = sbs)
(ORACLE_HOME = /u01/app/oracle/product/11.2.0/db_1)
(SID_NAME = sbs)
)
)
LISTENER_SBSDR =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.6.1.73)(PORT = 1522))
)
ADR_BASE_LISTENER_OEMGC = /u01/app/oracle
tnsname.ora file at standby side
sbs =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.6.1.74)(PORT = 1522))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = sbs)
)
)
sbsdr =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.6.1.73)(PORT = 1522))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = sbs)
)
)
Check Listener and Start (StandBy Database):
$ lsnrctl
$ status
$ start LISTENER_SBSDR — (Listener_Name)

Check the Both Server tns is working or not (tns Service):
$ tnsping sbsdr [from primary]
$ tnsping sbs   [from primary]
$ tnsping sbs [from standby]
$ tnsping sbsdr [from standby]
Step 5: PREPARE Primary DATABASE
(1) Moving database at force logging mode
SQL> ALTER DATABASE FORCE LOGGING;
(2) Create Standby redolog [Primary Database]
Connect to the physical standby database, and create the standby redo logs to support the standby role. The standby redo logs must be the same size as the primary database online logs. The recommended number of standby redo logs is:
(maximum # of logfiles +1) * maximum # of threads

This example uses two online log files for each thread. Thus, the number of standby redo logs should be (2 + 1) * 2 = 6. That is, one more standby redo log file for each thread.
You can check the number and group numbers of the redo logs by querying the V$LOG view: [Primary Databse]
SQL> SELECT * FROM V$LOG;
SQL> SELECT * FROM V$LOGFILE;

SQL>ALTER DATABASE ADD STANDBY LOGFILE GROUP 4 (‘/sdata2/redologs/sbs/redo04.log’) SIZE 50M;
SQL>ALTER DATABASE ADD STANDBY LOGFILE GROUP 5 (‘/sdata2/redologs/sbs/redo05.log’) SIZE 50M;
SQL>ALTER DATABASE ADD STANDBY LOGFILE GROUP 6 (‘/sdata1/redologs/sbs/redo06.log’) SIZE 50M;
SQL>ALTER DATABASE ADD STANDBY LOGFILE GROUP 7 (‘/sdata1/redologs/sbs/redo07.log’) SIZE 50M;
(3) CONFIGURE PRIMARY DATABASE PARAMETER CHANGE

alter system set log_archive_dest_state_2=’DEFER’ scope=both;
*.standby_file_management=’AUTO’
alter system set standby_file_management=’AUTO’ scope=both;

(4) GATHER FILES AND PERFORM BACK UP
On the primary node, create a Backup directory at primary Database :
$ mkdir -p /u01/rman/backup_dg/
Create the same exact path on the [ standby host ]:
$ mkdir -p /u01/rman/backup_dg/
On the primary node, connect to the primary database and create a PFILE from the SPFILE in the staging directory. [primary node 1]
SQL> CREATE PFILE=’/u01/rman/backup_dg/initsbs.ora’  FROM SPFILE;
On the primary node, perform an RMAN backup of the primary database that places the backup pieces into the staging directory.
$ rman target /
run
{
allocate channel c1 type disk;
allocate channel c2 type disk;
allocate channel c3 type disk;
backup database format ‘/u01/rman/backup_dg/DATA_%U’;
backup archivelog all format ‘/u01/rman/backup_dg/ARC_%U’;
backup current controlfile for standby format ‘/u01/rman/backup_dg/CTL_%U’;
release channel c1;
release channel c2;
release channel c3;
}
Copy the contents of the staging directory on the primary node to the staging directory on the standby host.
$ scp /u01/rman/backup_dg/*  oracle@sbsdr: /rman/backup_dg/

TRANSFER PASSWORD FILE AND RENAME
To enable secure transmission of redo data, make sure the primary and physical standby databases use a password file, and make sure the password for the SYS user is identical on every system.
$ cd $ORACLE_HOME/dbs
$ orapwd file=orapwsbs  password=XXXXX
            $ ftp sbsdr
            $cd $ORACLE_HOME/dbs
            $mput orapwsbs1
Rename orapwsbs to orapwsbs at standby side
Copy and rename the primary database PFILE from the staging area on the standby host to the $ORACLE_HOME/dbs directory on the standby host. [ standby host ]: 
$scp initsbs.ora  $ORACLE_HOME/dbs/initsbs.ora
Modify the standby initialization parameter file copied from the primary node to include Data Guard parameters as illustrated in the following table: [ standby host ]:
*.audit_file_dest=’/u01/app/oracle/admin/sbs/adump’
*.audit_sys_operations=TRUE
*.audit_trail=’DB’,'EXTENDED’
*.cell_offload_processing=FALSE

*.standby_file_management=’AUTO’
STANDBY DATABASE RESTOR & RECOVER
After setting up the appropriate environment variables on the standby host, such as ORACLE_SID, ORACLE_HOME, and PATH, start the physical standby database instance without mounting the control file. [ standby host ]
SQL> STARTUP NOMOUNT
From the standby host, duplicate the primary database .  [ standby host ]
$ rman target sys/XXXXX@sbs  auxiliary /
 RMAN> DUPLICATE TARGET DATABASE FOR STANDBY NOFILENAMECHECK DORECOVER;
Perform the following activity on Standby Database Server
Start Physical standby database
SQL> alter database mount standby database;
Initiate Log apply services
Run the following command on standby database
The example includes the DISCONNECT FROM SESSION option so that log apply services run in a background session.

SQL> ALTER DATABASE RECOVER MANAGED STANDBY DATABASE USING CURRENT LOGFILE DISCONNECT;
Put standby database on normal stage as before ( Log Apply services mode)
Create Server Parameter File on Standby Database Server
SQL> CREATE SPFILE FROM PFILE=’Path/Name.ora’;
SQL>shutdown immediate;

SQL>startup nomount;
SQL> alter database mount standby database;
SQL> ALTER DATABASE RECOVER MANAGED STANDBY DATABASE CANCEL;
SQL> ALTER DATABASE RECOVER MANAGED STANDBY DATABASE DISCONNECT;
Database open into Read only mode
SQL> ALTER DATABASE RECOVER MANAGED STANDBY DATABASE CANCEL;
SQL> ALTER DATABASE OPEN READ ONLY;
SQL> ALTER DATABASE RECOVER MANAGED STANDBY DATABASE USING CURRENT LOGFILE;
Step 6: VERIFY DATA GUARD CONFIGURATION
Test Case 1:
-Verify database role
On the primary server
SQL> select database_role from v$database;
DATABASE_ROLE
—————-
PRIMARY
On the standby server
SQL> select database_role from v$database;
DATABASE_ROLE
—————-
PHYSICAL STANDBY
Test Case 2:
-The “alter system switch logfile” command forces a log switch.
On the primary server
-The “alter system switch logfile” command forces a log switch.
SQL> alter system switch logfile;
System altered.
SQL> archive log list
