STARTING STANDBY IN DATAGUARD CONFIGURATION

Hi,
IN DATAGUARD CONFIGURATION, should we start STANDBY database by :
1-STARTUP MOUNT
or
2-STARTUP
or
3-STARTUP MOUNT
ALTER DATABASE RECOVER MANAGED STANDBY DATABASE DISCONNECT;
Many thanks before.

Thank you sybrandb.
Please always include your version (four digits) and the O/SPROD 10.2.0. on WIN 2003 SERVER
STANDBY 10.2.0. on WIN XP PRO.
The correct procedure is (documented)Thank to give the name or number or URL of document. I have already seen :

Multiple Standby Dataguard Configuration

Hi,
Sorry if this has been posted before, but I could not find the answer.
I have a Primary site (PRIM) and one Standby site(STBY1). The standby receives archive log changes from the primary. Also using dataguard to manage the Standby.
I would like to create another standby (STBY2) and use the current standby (STBY1) to send changes to the other standby (STBY2).
I've read the section on Cascade Redo Log Destinations in Section D of the Dataguard doc, but it really doesnt show how this is configured.
I assume that my standby (STBY1) would need a the log_archive_dest_2 set to the service that points to the second standby (STBY2).
My question is.. Do I need to be using Maximum Availibilty and send redo logs vice archive logs? How do I configure dataguard? Is the second standby (STBY2) another site in the dataguard configuration?
Thanks,
Roland

I'm curious, is there a reason that you wouldn't want PRIM to supply the changes to both STBY1 and STBY2? In the configuration you're describing, if there was a failure on STBY1, you couldn't fail over from PRIM to STBY2...

Database upgrade in a Dataguard Configuration - Help !

Hello Everyone,
I am upgrading our test Oracle 11G RAC/Dataguard Configuration from 11.1.0.6 to patchset 11.1.0.7 and have run into an issue when trying to apply the patchset to one of our standby databases.
I have upgraded our primary database to 11.1.0.7 with no problems, however when this was done the Dataguard Broker configuration was disabled and redo log apply to our standby databases (all physical) was stopped. I next attempted to upgrade one of our standby databases to 11.1.0.7, whilst DG Broker was disabled. The clusterware (all our databases are part of RAC clusters) and DB Software upgrades were OK, but I was unable to run DBUA successfully (or at all) as it wont run against the standby DB.
Looking at the process for applying upgrades with Physical Standby databases in place in the Dataguard Concepts manual, it seems as though the recommended process is that I should have upgraded the standby database(s) first rather than the primary database. The two Oracle Consultants that were on site when I upgraded the primary DB, did not seem to be aware of this !
What now is the easiest (and quickest) way of upgrading the standby db to 11.1.0.7 (preferably without reenabling the DG Broker Configuration). Is it possible to re-instanitate the standby DB from the primary DB?
Any advice would be much appreciated.
Thanks,
Shaun.

Hi!
Updating a standby DB must be so easy, but I suppose now you are in troubble because your primary DB is ...0.7 and standby are ...0.6, but in this situaction there isn't any problem. You only need to have same version at Oracle DBs (...0.7) and initiate the recovery process or start DataGuard Broker process (if you have all redo logs since the beggining of update process).
Chiao!

Standby without DataGuard

Hi,
I've successfully created a standby for a single node Primary Database in 10g on Redhat Enterprise Linux 4.0 Update 4.0. I'm planning to add one more standby site to the same primary database. Now, my question is...
1. Is it possible to setup more than one standby without the help of DataGuard.
2. If possible, please guide me how to do it(step-by-step).
Thanks in advance...
Mahesh

If you've already configured one Standby without DataGuard, you'd use the same method for the second standby.
Since we do not know your scripts and how you are propagating archive logs and putting the standby in recovery mode -- all of which would be "custom" methods in the absence of DataGuard -- we can't really advice you . Because it is difficult to advice on extensions to a customisation without looking at a customisation.
Many sites have implemented a scripted Standby without DataGuard using methods available since Oracle7. However, the frequency and method of archivelog propagation and how and when the standby database "wakes up" to apply the archivelogs etc are all site specific.
Let's say that you DO use the ARCH process on the primary database to propagate archivelogs to the Standby destination site. Since Oracle 10g allows multiple log_archive_dest_n sites, you can just add one more site and have the archivelogs propagate to the additonal site. However, there are other parameters (eg MANDATORY/OPTIONAL, REOPEN, DELAY etc) that you would set based on your requirements.
The two standby instances would be independent {unaware} of each other -- you can script delays between the archivelogs so that the two standby aren't always at the same level (this allows "fallback" to an "older version of the database" when necessary). You could have one standby stop recovery and open read only for some time.
Short Answer : Yes, it is possible to have multiple "standby"s without DataGuard.
Correct Answer : How you do it depends on how you want to extend your current implementation.

Upgrade of database in Dataguard Configuration

Hi,
I have few doubts regarding upgrading of database in in a dataguard configuration. Could someone please help me out.
- How does upgrade happen in dataguard configuration?
- Is that we have to install only different OH in both? And once the catupgrade script is run on primary, it will automatically upgrade standby as well?
- Or is that we have to upgrade both separately? i.e, standby first and then primary or vice versa
- Can we reduce downtime by breaking the dataguard config. Do a switchover and make secondary as primary and upgrade primary first?
And once the upgrade is completed in primary, bring it up and later upgrade the standby. And later once the upgrade is completed on standby, synch both primary and standby.
Please share your ideas and thoughts!
Thanks!

First of all, -steps may differ regarding the upgrade versions but- my post with the following link would help you clarify the concept.

Breaking DataGuard Configuration

Hi
We are in process of doing database upgrade in dataguard configuration and we are planning to break the dataguard configuration and we will do the upgrade in standby database then we will do it in primary. My questions here is
1)I am going to break the Dg configuration like disabling the DGBROKER,unset the archivelog dest,dg_broker_start=false.....so onnn
2)How to open the standby database in readwrite mode.
DB VERSION IS 9.2.0.6
os is WINDOWS-2000
kk

Hi Ogan,
Can i do the following steps to break primary and standby.
1)DISABLE DATAGUARD BROKER CONFIGURATION
2)STOP MRP PROCESS ON STANDBY --->ALTER DATABASE RECOVER MANAGED STANDBY DATABASE CANCEL;---->
3) On the primary disable any archive destinations that are archiving to the standby:
SQL> select dest_id,destination,status from v$archive_dest where target=’STANDBY’;
SQL> alter system set log_archive_dest_state_2=defer scope=both;
4)on standby database mount standby database and issues the below command
ALTER DATABASE COMMIT TO SWITCHOVER TO PRIMARY;
if i do like this is it going to work as primary???

9i Standby without dataguard

Hi all.
Oracle 9i ( SE )
I'm trying to figure out how to create a standby database without dataguard. I've read that its possible, but I can't find any documentation on exactly how to do it. From what I've gathered I should be able to
Create a duplicate database from primary backups
Put standby database into "some recovery mode" - this is the bit I'm stumped at
Copy archive logs from primary to standby, where they will magically be applied?
I need to migration lots of datafiles to new disks, and cannot afford the downtime to just move them, so I'm thinking the best way to do it is to create a standby and keep it as close to synced to the primary as possible, then shutdown primary, apply file logs, point primary to the new datafile location..
Can anyone either point me to a good article on doing standby with dataguard, or if there is a better way to move large ( move procedure will take about 4-5 hours) tablespaces/databases with minimum downtime.
Thanks.

Hrmm, maybe? so is "Data Guard" by itself available for SE?
When I startup the database it reports
"Oracle Data Guard is not available in this edition of Oracle."
I'll go poke around that document too.
btw. the document I read which suggests this is possible is, http://www.dba-oracle.com/oracle_tips_failover.htm
Thanks

Third party backup software support for dataguard configurations

Any Oracle document about the subject?
I would be interested in an answer about backupexec 2010 r2 in particular, because reading the manual for its oracle agent there is information about Oracle/RMAN and RAC support, but nothing about Dataguard integration, that could be a value added.
Anyone using third party backup agents in a Dataguard configuration?
Interested in version 11gR2 on Linux.
Thanks,
Gianluca

yes, you should be able to use the full backup taken in middle and use the rest of the log backups taken afterwards to restore the database.while I do not use TSM, we use QUEST(DELL) LITESPEED, that takes full backup once a day and log backups
every 15mins.
if someone accidentally takes full backup in the middle of day with out 'copy only',
log sequence will break and successive log backups depend on this full back up.
while this should be prevented from happening in first place, you can still restore from native full backup and then apply log backups taken from third party taken after the native Full backup.
if this happens, I would restore the FULLBACKP with NORECOVERY using NATIVE SQL and then use lite speed syntax to restore the log backups.Remember, native sql cannot read third party formatted backups(atleast litespeed), thats why I restore the full backup
using native sql, since it was taken with native sql backup and log backups using litespeed syntax.
Hope it Helps!!
Thanks, well it was just a theory discussion we had about the issue. But none of us could find info on the internet easy to prove our point :) Thanks.

Error starting the SOAMANAGER for Configuration

Hi fellows,
I've created a web service from a RFC. When I tried to start the SOAMANAGER for configuration to create the an endpoint I've got the error bellow:
"Invalid index 1 when setting lead selection; context node: MAIN.1.NODE_SEARCH_TABLE"
I tried to acess the SOAMANAGER transaction to find the service description created. I found it but when I tried to create the endpoint I got the errors:
"Error: Error when reading variant "ZWS_TESTE" of servicedefinition "ZWS_TESTE": An exception with the type CX_SY_REF_IS_INITIAL oc "
And
"No service/endpoint selected"
Someone knows what am I missing?

Hi Douglas,
While searching the service defintion in Soamanager i get the error.
"Error: Error when reading variant "ZSAPCONNECTORWEBSERVICE" of servicedefinition "ZSAPCONNECTORWEBSERVICE": An exception with the type CX_SY_REF_IS_INITIAL oc ".
How to solve this

Physical standby without dataguard

Naive question.
I am going thru metalink note (374069.1) on how to create a physical standby. In that note, they didn't mention data guard stuff. Am I to assume that physical standby without dataguard can be created?
Thanks.

It might appears to be easy to create psuedo standy but you will have hardtime to simulate the automatic archive log apply and gap resolve.
Plus the level of data availability provided by self-managed standby can't come close to Data Guard can offer.
With Data Guard you can almost get zero data loss between Primary and Standy, depends on your redo logfile size there could be many data in online redo logs.

Getting error: java.lang.IllegalStateException: Service has been started by a different configurable cache factory.

We are trying to implement host name based security for our Coherence cluster. This is mainly to prevent processes running in one environment (UAT for example) connecting to the Coherence cluster running in another environment (PROD for example).
We wanted to ensure that 1) Only Coherence nodes running on specific machines can join the cluster as members. To accomplish this, we added the list of authorized hosts to the override file (see marketrisk-coherence-override.xml) This works as expected with no issues
We also want to ensure that we allow client connections from some specific machines. All of our clients connect to the cluster through the proxy. So, we added added a host filter to the cache config file (see marketrisk-cache-config.xml) to control the list of client machines that can are allowed to connect to the cluster. The host filter is pretty simple. If the incoming host address is found in a cache, it allows the connection else it refuses the connection. Please see AuthorizedClientHostsFilter.java for more details.
When we start the cluster, the storage nodes are failing to come up with the following error message:
Exception in thread "main" java.lang.IllegalStateException: Service "ReferenceDataCacheService" has been started by a different configurable cache factory.

                at com.tangosol.net.DefaultCacheServer.main(DefaultCacheServer.java:260)
This error goes away and the cluster starts normally if we remove host filter from the cache config file or we modify AuthorizedClientHostsFilter.java to not get a handle to the cache when it is instantiated. Please see AuthorizedClientHostsFilter1.java which has this change.
We believe this is happening because the storage node is creating two cache factories when we use the host filter (AuthorizedClientHostsFilter.java). The storage nodes creates only one cache factory if we do not use the host filter or if I use AuthorizedClientHostsFilter1.java.
I do not understand why this is happening. Can you please help? The attached zip file should have all the information that you will probably need.

In my standby dataguard configuration

Hi All,
I observed one strange thing in my database is that my archives are getting shipped regularly to DR site but in night time only it starts to getting applied. Some time, it starts to apply but its very slow. I confirmed with network team and they said that there is no problem in connectivity.
Could anyone tell me about this please ?

I'm curious, is there a reason that you wouldn't want PRIM to supply the changes to both STBY1 and STBY2? In the configuration you're describing, if there was a failure on STBY1, you couldn't fail over from PRIM to STBY2...

Standby database not configure while keep database files in different place

Dear Friends ,
I have to successfully configured "PHYSICAL STANDBY DATABASE" within the TWO databases ("PRIM" and "STAN" Database) when I kept datafile, controlfile and redolog files in the same location (like, "/u01/app/oracle/oradata/prim" location .
In this successful configuration , I have to add the below two lines into the initprim.ora and initstan.ora both server respectively ...
initprim.ora:
========
DB_FILE_NAME_CONVERT='/u01/app/oracle/oradata/stan','/u01/app/oracle/oradata/prim'
LOG_FILE_NAME_CONVERT='/u01/app/oracle/flash_recovery_area/stan','/u01/app/oracle/flash_recovery_area/prim'
initstan.ora:
========

LOG_FILE_NAME_CONVERT='/u01/app/oracle/flash_recovery_area/prim','/u01/app/oracle/flash_recovery_area/stan'Now , in second scenario , I have to change Primary database server's datafile, controlfile and redolog file in the below folder :
controlfile --> "/u01/app/oracle/oradata/prim/ctrlfile"
redologfile --> "/u01/app/oracle/oradata/prim/redofile"
datafile --> "/u01/app/oracle/oradata/prim/datafile"
Similarly I have to create same folder in my STAN database server accordingly . and also add the above lines in same way :
initprim.ora:
========
DB_FILE_NAME_CONVERT='/u01/app/oracle/oradata/stan','/u01/app/oracle/oradata/prim'
LOG_FILE_NAME_CONVERT='/u01/app/oracle/flash_recovery_area/stan','/u01/app/oracle/flash_recovery_area/prim'
initstan.ora:
========
DB_FILE_NAME_CONVERT='/u01/app/oracle/oradata/prim','/u01/app/oracle/oradata/stan'
LOG_FILE_NAME_CONVERT='/u01/app/oracle/flash_recovery_area/prim','/u01/app/oracle/flash_recovery_area/stan'Keeping the above situation when I run the below command in STAN database server :

Would u plz suggest me , why I cannot configure Physical Standby Database when I keep my database fles in the separate location ?
help me plz ... ...

Hi,
I'm missing the steps you took renaming/moving the files on the primary.
Since the location of datafiles is stored in the control file the controlfile of the standby might not know the new location yet.
I suggest you read this http://www.cs.bris.ac.uk/maintain/OracleDocs/server.816/a76995/standby.htm#23603 and see if that helps
Success,
