Primary and standby init file (switchove/failover)

I have created standby database, its working fine, and logs are copying and being applied. I have successfully opened standby database in read only mode.
Now I want to perform switchover and failover, please check parameters in init file that I have added.
Primary database init file :
*.control_files='D:\oracle\product\10.2.0/oradata/primary/\control01.ctl','D:\oracle\product\10.2.0/oradata/primary/\control02.ctl','D:\oracle\product\10.2.0/oradata/primary/\control03.ctl'
*.db_name='primary'
*.db_unique_name='PRIMARY'
*.dispatchers='(PROTOCOL=TCP) (SERVICE=primaryXDB)'
*.log_archive_dest_1='location=D:\oracle\product\10.2.0\oradata\archive'
*.log_archive_dest_state_1=ENABLE
*.log_archive_dest_state_2=ENABLE
*.log_archive_dest_2='SERVICE=standby LGWR ASYNC'
*.log_archive_format='arc_%s_%t_%r.arc'
*.fal_client='PRIMARY'
*.fal_server='STANDBY'
standby database init file :
*.control_files='D:\oracle\product\10.2.0/oradata/primary/STANDBY_CONTROL.CTL'
*.db_name='primary'
*.db_unique_name='STANDBY'
*.dispatchers='(PROTOCOL=TCP) (SERVICE=primaryXDB)'

*.log_archive_format='arc_%s_%t_%r.arc'
*.log_archive_dest_state_2=ENABLE
*.fal_server='PRIMARY'
*.fal_client='STANDBY'
*.standby_file_management=auto
Please let me know if I need to add/modify any parameter to perform switchover & failover operations.

Require 9i Primary and Standby redo logs files same size?

Hi,
We have 9.2.0.6 Oracle RAC (2 node) and configured data guard (physical standby).
I want to increase redo log files size, but i can't this do same time primary and standby side.
Is there a rule, primary and standby database instances have same size redo log files?
If I increase only primary redo log files, is there any side effect? However I try this issue on test system. I increased all primary redo log files(if status='INACTIVE' drop redo log group and add redo log group, switch logfile,...)
, but i couldn't changed standby side. So the system is work well. Is this correct solution or not? How can i increase both sides redo log files?
Thank you for helps..

Thank you for your helps.. I found this issue answer:
http://download-west.oracle.com/docs/cd/B19306_01/server.102/b14239/manage_ps.htm#i1010448
Consequently, when you add or drop an online redo log file at the primary site, it is important that you synchronize the changes in the standby database by following these steps:
If Redo Apply is running, you must cancel Redo Apply before you can change the log files.
If the STANDBY_FILE_MANAGEMENT initialization parameter is set to AUTO, change the value to MANUAL.
Add or drop an online redo log file:
To add an online redo log file, use a SQL statement such as this:
SQL> ALTER DATABASE ADD LOGFILE '/disk1/oracle/oradata/payroll/prmy3.log' SIZE 100M;
To drop an online redo log file, use a SQL statement such as this:
SQL> ALTER DATABASE DROP LOGFILE '/disk1/oracle/oradata/payroll/prmy3.log';
Repeat the statement you used in Step 3 on each standby database.
Restore the STANDBY_FILE_MANAGEMENT initialization parameter and the Redo Apply options to their original states.
bye..

Oracle data guard configuration for primary and standby db_name

I am working on configuring an active data guard for one primary DB and one standby DB. I have a few questions:
1. Can I use different db_name, db_unique_name and instance_name for primary and standby. For example: primary(db_name, db_unique_name and instance_name)=chicago. When I create standby DB with Rman backup and copy of pfile and control file from primary DB or use Grid control to create standby database. Oracle document or Grid control all keep standby db_name=chicago. Only make standby db_unique_name and instance_name=boston. Due to my application system condition, I want to make db_name=boston, not keep it as the same as primary=chicago. Is this valid configuration?
2. In primary datafiles, application system generate datafile name like this: hr_chicago_01.dbf, fn_chicago_01.dbf. When I move datafiles to standby server, if I plan to use db_name=boston for standby DB, can I rename datafiles as
hr_boston_01.dbf, fn_boston_01.dbf? In this way, datafile name match up with db_name. but I will create standby log group and members on primary and standby identically. If in future switching over, DB will not have problems.
3. If I don't use primary DB backup. Instead, I copy all datafiles, redo_log files (no control files) to standby. Then "alter database backup controlfile to trace" from promary and also " create pfile='/xxx/initSTANDBY.ora' from primary. Then modify init.ora and controlfile. Then run control.sql to bring standby DB up. After that, configure redo log shipping and apply with data guard or SQL. Is this a acceptable way to create physical standby DB?
Please advise your comments. Thanks in advance.

I want to make db_name=boston, not keep it as the same as primary=chicago. Is this valid configuration?NO. DB_NAME must be the same ("chicago") at both sites. The Standby will be using a different DB_UNIQUE_NAME (e.g. "boston") and can be using a different Instance name / SID (e.g. "boston").
can I rename datafiles Yes. The database file names can be changed.
If I don't use primary DB backup. Instead, I copy all datafiles, redo_log files (no control files) to standbyWhat is the difference between the first sentence (a backup of the primary) and the second sentence (a copy of the primary) ? A Copy is a backup.
Are you intending to differentiate between an RMAN Backup and a User-Managed (aka "scripted") backup ?
Normally, for DataGuard, tou can use non-RMAN methods to copy the database but there's no value add in this.
You'd still have to setup DataGuard ! (and I wonder if you'd have complications setting up Active DataGuard).
But remember that you MUST create the Standby controlfile from the Primary and copy it over to your Standby -- particularly as you are planning to use DataGuard. This is not created by 'alter database backup controlfile to trace' , but by 'ALTER DATABASE CREATE STANDBY CONTROLFILE AS 'filename''

How to configure Enterprise Manager Database Control (EMDC) to make it work on 2 servers working (primary and standby) under DG rules

Hello everybody i use Oracle Database EE 11.2.0.4 with DG.
In those cases i need to get Enterprise Manager Database Control running against DB with no RAC and no DG i perform the following steps:
I Logon SQLPLUS as user SYS or SYSTEM, and drop the sysman account and management objects:
DECLARE
CURSOR c1 IS
SELECT owner, synonym_name name
FROM dba_synonyms
WHERE table_owner = 'SYSMAN';
BEGIN
FOR r1 IN c1 LOOP
IF r1.owner = 'PUBLIC' THEN
EXECUTE IMMEDIATE 'DROP PUBLIC SYNONYM '||r1.name;
ELSE
EXECUTE IMMEDIATE 'DROP SYNONYM '||r1.owner||'.'||r1.name;
END IF;
END LOOP;
END;
DROP USER mgmt_view CASCADE;
DROP ROLE mgmt_user;
DROP USER sysman CASCADE;
After that i run
emca -config dbcontrol db -repos recreate
But what should i do in cases i have 2 servers working (primary and standby) under DG rules?

Hi ,
It is not possible to monitor/administer a Logical or Physical Standby database, i.e Data Guard, using Enterprise Manager Database Control. This is primarily due to the fact that Database Control is designed to monitor 1 database and a Data Guard environment, by definition, includes more than 1 database.
If you attempt to run emca against a standby Database, you will get an error like (i.e. ORA-01219: database not open).
Database Control, can, of course, be used to monitor the current Primary database (with no ability to administer or monitor Data Guard related functionality). In such a case, when failover occurs Database Control must be reconfigured to run on the new Primary database using the commands detailed in Note 278100.1 How To Drop, Create And Recreate DB Control In A 10g Database, section C. Recreate/ReConfig DB Control, Option 2. Recreate the DB Control Configuration Files and Repository.
Enterprise Manager Grid Control or Cloud Control provides the functionality for viewing, monitoring, and administering primary and standby databases in a Data Guard configuration.
Reference: Is it Possible to Configure Database Control for a Logical or Physical Standby Database? (Doc ID 315116.1)
You can use EM 12c cloud control to monitor and manager Standby DB effectively

How to re-synch primary and standby database?

Hello everyone,
Working on 10g R2/windows server 2003, I have configured a physical standby database but, I have an issue, and don't know how to resolve it.
We were making an update that made some DDL and DML on our application, and for security reason we
1. we ensure that primary and standby are in sync
2. We made a cold backup of the primary database
3. We Deferred the redo shipping between primary and standby
4. We applied changes on primary database
But the big issue is that, for any reason my colleague did the following.
a) made above steps 1,2,3,4
b) after the update he kept the resulted archived log files generated during to another location
c) He restore the cold backup before the update(step 2 above)
c) he applied again the update.
Now the issue is
At the first update step(2), the sequence# 553 was applied to the stand by before the update
At the second update step(c) above another sequence# 553 was created but stored localy in the primary database, because the both servers were deverged (step 3 above).
Technically both servers cannot be in sync again,because sequence# 553 at the first update has next_change# 80307804 and sequenc# 553 at the second update has next_change# 80461356.
Question:
How Can I do to rollback the the first sequence# 553 ( before the first update) on the standby database? in order to apply the sequence#553 generated at the second update and then re-sync both servers to roll forward subsequent sequence#? 554,etc...
Thank you for your help

Primary and Standby CM question

In general, Primary and Standby CM's database tables, configurations, group polices should be sync'd up and looked identical, right? What else will be different and will require to import onto standby CM manually? Things like: SSL certificate, Secure store encryption...etcs.
Thanks!
Joe

Hello Joe,
I don't think you're leaving anything behind in regards how primary and standby CM sync works, just follow the steps from the configuration guide and everything will be taken care,if there was any doubt just let us know what WAAS software version your running and the specific question. Critical files like Secure-store and SSL certificates will be automatically sync as well.
Still, in my experience I stronly suggest to make sure your devices time settings are right.
Time settings is very important for the sync to work fine, best way is to use an NTP.
Please find the attached link to configure NTP and timezone:

Logfile groups for Primary and Standby

Hi,
Oracle documents say that the size of Log files should be the same for primary and Standby. Presently it is not the case. I have logfile 100M for Primary (PROD) and 50M for Standby. To change them I should add new groups with file of 100M to standby. And then drop the small logs(50M). in this case the group number would not be the same. Would it be a problem ? Any other solution ? Thank you.

.Oracle documents say that the size of Log files should be the same for primary and Standby. It is only a recommendation, but, not mandatory. However, a messaage will be written to the standby alertlog file when standby database log file size is smillar than its primary database log file size.
in this case the group number would not be the same. Would it be a problem It won't be a problem.

Configure active and standby mac address in failover

Hi guys,
I just have a doubt that, if I configure the active and standby mac address in failover, does it will cause any downtime?
As I planning to configure the active and standby mac addresses in failover during production time and not wish that it will bring any downtime to me.
Besides that, just need some guideline that do I need to put all the interfaces' mac addresses in failover?
failover mac address GigabitEthernet0/0 0022.90fe.2000 0022.90fe.2001
failover mac address GigabitEthernet0/1 0022.90fe.3000 0022.90fe.3001
failover mac address GigabitEthernet0/2 0022.90fe.4000 0022.90fe.4001
failover mac address GigabitEthernet0/3 0022.90fe.5000 0022.90fe.5001

Hi Marius,
Seem like set the failover MAC address was not working for me.
Last friday I was tested the failover MAC address.
TEST 1
1, Power off primary ASA and secondary ASA work as active.
2, 2821 router able to learn the correct arp entries.
TEST 2
1, Power on primary ASA and failover from secondary to primary.
2, 2821 router able to learn the correct arp entries from ASA.
3, Set failover MAC address, power off primary ASA and secondary ASA be active.
4, 2821 router unable to learn the correct arp entries.
TEST 3
1, Removed failover MAC address from secondary ASA.
2, 2821 router still unable to learn the correct arp entries from ASA.
3, Power up primary ASA and secondary ASA still in active.
4, 2821 router still unable to learn the correct arp entries from ASA.
5, Reboot 2821 router and it able to learn the arp entries from ASA.
I am not sure this issue from router or from the ASA. But I guess I will try to upgrade the router in term of software and hardware.

Shell script to find MAX(SEQUENCE#) of primary and standby DB.

Hi All,
AIX 5.3 64bit DB:10.2.0.3.0
I am looking for a shell script which does the following:
Use SQL*Plus to query the MAX(SEQUENCE#) from both databases i.e., Primary and standby V$LOG_HISTORY view. If the STANDBY appears to be falling behind by 2 archive log files,then send alert mail to: [email protected]
We should be able to connect to primary DB from standby DB using ssh
For example: ssh ora<user>@hostname.domain
I use the following query to find out MAX(SEQUENCE#):
col logseq_on_standby new_value V_STDBY_LOGSEQ
select /*+ rule */ max(h.sequence#) logseq_on_standby
from v\$log_history h,
v\$parameter p
where h.thread# = to_number(decode(p.value,'0',1,p.value))

Standby database(11g) was still in sync after stopping the primary and standby database listener.

Hello !!!
I have noticed that my standby database(11g) was still in sync after stopping the primary and standby database listener.
If this is the case then how log is transferring from primary to standby ? it is not using listener service ? kindly clarify

Read this Metalink Note:407040.1

Sequence of stopping starting Primary and standby DB

Hi,
what are the sequence of stopping starting Primary and standby DB ?
To stop, which one ,primary or Standby, should be stopped first ?
To Start which one first ?
Thank you.

Hi,
what about the 10gR2 logical standbys? When I read the Note:278643.1 to apply the patch for logical database, it seemed that the sequence to stop and start the primary/logical standby was to stop the logical standby first before the stop of the primary one. Please advise me, for a simple situation just to stop and start the primary/logical standby to support a Unix server bounce, what is the sequence we should follow ? Do we have to run some commands to stop/start the SQL apply?
Any idea or suggestion will be greatly appreciated.
Thank you very much,

How to sync primary and standby database in 11GR2 on linux

Hi ,
How to sync primary and standby database in 11GR2 on linux . Both my primay and standby are 3 node cluster each.
Can you please suggest a good link and brief steps .
Thanks

Are you trying to setup a new standby or sync an existing standby database?
OK I see it
"standby is behind the primary"
So you have a gap.
I would check both alert logs for a cause. You might find something like this
ORA-12514: TNS:listener does not currently know of service requested in connect descriptor.Look for ORA-00308 and ORA-27037 and ORA-16055.
There's no sense fixing the gap unless the cause is fixed too.
Also check out this post from a few days ago its dealing with similar issues.

Can I have primary and standby in same OS but different releases.

All,
Can I have primary and standby DBs in same OS but in different releases?
i.e. primary is in RHEL 5 and standby is in RHEL 4, is it ok to setup or do we see any issues?
Thanks,

DNS / BIND - Can I configure primary and standby forwarders?

Hi all,
I have on Solaris 10 (x86) a DNS server (BIND 9.3.6-P1) that relies exclusively on two “forwarders”: 155.28.144.13and 154.23.134.32.
The configuration is as follow:
# cat /etc/named.conf
acl "CSClan" { 192.168.4.0/24; 192.168.7.0/24; }; //CSC internal LAN ip address range
options {
        directory "/var/named";
        forward only;
        forwarders {
                155.28.144.13;
                154.23.134.32;
             allow-query { "localnets"; };
# cat /etc/resolv.conf
nameserver 127.0.0.1
When I check with snoop, I can see requests sometimes to one forwarder, sometimes to the other.
Is it possible to configure DNS to use primarily one forwarder?
Thanks in advance for your support.

In 10g, dataguard started to support different binaries on primary and standby database servers with the same OS family. For example Microsoft Windows 64-bit on primary and Microsoft Windows 32-bit or Microsoft Windows 64-bit for AMD on standby database server. However with 11g, dataguard also supports different OS on primary and standby servers
