Data guard related OS processes in Primary and Standby servers

Database version : 11.2.0.3
Operating System : RHEL 5.8
Type: Physical Standby
++++++++++++++++++++++++++++In a typical Linux server hosting a Physical standby DB, the data guard related OS processes that appear in ps output
are like below. One mrp for each standby DB.
ps -ef |grep mrp
oracle 9380     1   0   May 21 ?          57:33 ora_mrp0_STRYKER_DG
oracle 18874     1   0   May 23 ?          33:45 ora_mrp0_FLPSA
oracle 18992 18837   0 23:39:39 pts/3       0:00 grep mrpSimilarly ,In a typical Linux server hosting a Primary DB what are the data guard related OS processes that appear in ps output ? Will LNS process appear in ps output ? Any other processes ?

Similarly ,In a typical Linux server hosting a Primary DB what are the data guard related OS processes that appear in ps output ? Will LNS process appear in ps output ? Not exactly but it appears has different name, on your primary try below commands
SQL> select pid from v$managed_standby where process='LNS';
$ps -ef|grep <pid value>
hope this helps, on standby you can use same procedure to find the RFS OS process

Data Guard Archive Log Latency Between Primary and Physical Standby

How can I get the time it takes (latency) for the primary instance to get an archive log over to the physical standby instance and get it "archived" and "applied". I have been looking at the V$ARCHIVED_LOG view on each side but the COLUMN "COMPLETION_TIME" always shows a date "MM/DD/YY" and no timestamp. I thought the DATE datatype include data and time. Any ideas on how I can get the latency info I'm looking for?
Thanks
Steve

the COLUMN "COMPLETION_TIME" always shows a date "MM/DD/YY"
and no timestamp. Did you try using TO_CHAR ? e.g.
to_char(completion_time,'dd/mm/yyyy hh24:mi:ss')

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,
Mahi

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

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.

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''

Data Guard Broker fails with ORA-16635 and ORA-03135

Hi All,
I configured Oracle RAC with Dataguard 11.2 on Windows 2003.
I've already configured Standby without Data Guard Broker and everything is working fine, but when I try to use Data Guard Broker, he can not synchronize the files from the Data Guard Broker.
I've tried everything including MOS, but not found anything.
I'm getting this error.

Hi,
Are you using firewall between Hosts?
If yes check if firewall is blocking yours connections.
Set the following parameter in the sqlnet.ora file that would be referenced by each database, primary and standby.
SQLNET.EXPIRE_TIME=n
Where n is some number of minutes. Preferably below 10. When this parameter is enabled, a small 10 byte probe packet will be sent from node to node at specific intervals.

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

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..

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

DG primary and standby

Hi all,
11.2.0.1
Aix 6.1
I want to monitor the applied logs both on my primary and standby
using > select client_process, process, sequence#, status from v$managed_standby;
I want to issue the command on my client laptop so I want compare the output easily, whether logs are synch.
How can I connect to a standby database s which is not open using client?
Thanks a lot,
zxy

hi,

Purging archivelogs on Primary and Standby

Hi all,
11.2.0.1
Aix 6.1
I am monitoring space usage in our FRA for both DG primary and standby. I want to purge all archivelogs once they have been applied to standby. What is the use of it anyway?
I checked google and I found this procedure, kindly correct if this is wrong?
At Primary:
=========
RMAN
CONFIGURE ARCHIVELOG DELETION POLICY TO APPLIED ON STANDBY;
At Standby:
========
RMAN
CONFIGURE ARCHIVELOG DELETION POLICY TO NONE;
Where do I issue the command DELETE NOPROMPT OBSOLETE ARCHIVELOGS?
Thanks a lot,
zxy

Which tool in oracle dear maintains the FRA/achivelogs? is it RMAN or Dataguard. If it maintains
them auto, why is that I still have lots of archivelog at PRIMARY and STANDBY?

Taking RMAN backup of primary and standby databases.

Hi,
I am going to setup a Standby for Primary two node RAC to single node standby.
My doubt is, in standby both primary and standby will have the same db_name. So how can i take the RMAN backup of both primary and standby by using a single catalog.
That is, we can register the primary DB with catalog using it's db_name. But how can we register the standby with catalog using same db_name as it is already registered.
Thanks,
Mahi

Are you using a physical or logical standby?
If its a physical standby why do you need to back up both databases? backup the standby and you are done, the backup from the standby can be recovered to either the live serever or the standby if needed, andt hen the archivelogs used to bring it up to date.
If its a logical standby then change the database name for the standby and you can back both up to the same catalog, or alternativly cretae a new catalog for the standby, either as a new database or a new schema in your existing catalog.

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,
yKe
