Restore standby database 10gR2 after crash

The RMAN do a full backup of the physical standby of the DataGuard 10gR2 everyday.
If the standby was dead, disks corrupted, and replaced with a new server.
Can we restore the standby from the RMAN backup, apply the archivelogs or we have re-create the standby db from the primary ?
If possible to restore the standby from the RMAN backup, what are the procedure exactly ?
Is it like this:
     RMAN>     Startup force nomount;
     RMAN>     Restore spfile;
     RMAN>     Restore controlfile;
     RMAN>     Shutdown
     RMAN>     Startup mount
     RMAN>     Restore database
     SQL> Recover standby database until cancel;
## to start Redo Apply
ALTER DATABASE RECOVER MANAGED STANDBY DATABASE DISCONNECT FROM SESSION;

I believe there is no need to re-create the standby db from the primary because the RMAN backup is still valid so it's must be possible to get the standby db back from the RMAN. If anyone who has experience and could confirm this with the procedure. That would be great.Why not test it by your own? Create a standby database and practice. You can check my video tutorial on creating standby database:
http://kamranagayev.wordpress.com/2010/06/25/rman-video-tutorial-series-creating-duplicate-and-standby-database-using-rman/
Moreover, read the "Backing Up a Standby Database with RMAN" of the following documentation:
http://download-west.oracle.com/docs/cd/B10501_01/server.920/a96566/rcmbackp.htm#445993
Use the RMAN BACKUP command to back up the standby database. A backup of the standby database is exactly the same as a backup of the primary database, except that the backup takes place on the standby site. The primary database has no influence on the backup of the standby database. Note that when you connect to the standby database to perform the backup, you connect using the TARGET keyword and not the AUXILIARY keyword.
Whether the standby database backup is consistent or inconsistent depends on the state of the standby database when the backup is made. Only a consistent backup can be restored without performing media recovery.

Asynchronous CDC on a Logical Standby database (10gR2)

Hi,
Question:
Is it possible to setup Asynchronous CDC on a Logical Standby database (10gR2)?
Background:
In our Oracle Data Warehouse environment where we need to provide up-to-the-second "operational" reporting against a Logical Standby database (10gR2 Data Guard) as the production application database owners do not permit direct reporting against the Primary database (10gR2); we also have a Data Warehouse database (10gR2) that requires more sophisticated/summary reporting which is updated at less regular intervals from the Logical Standby database.
The complication is that although the Logical Standby database will serve the purpose of a 'syncronized' version of the Primary database by giving us a current-state view of the data, we require more detailed change data capture on certain tables to audit change history between the points we extract data for the Data Warehouse.
The DBAs do not want to set-up Asynchronous CDC on the Primary database, so is it possible to setup Asynchronous CDC on a Logical Standby database?
Anyone done it before?
Any issues?
Any alternatives?
Any help would be much appreciated.
Thanks

As far as I know it is but it would be easier, and more robust, to just create a second logical standby and feed them both from the primary.
Logical Data Guard and Streams are essentially just two implementations of the same technology written by the same team of developers.

How to restore standby from primary after failover.

HI we have a dr setup but the standby is provided archives through an application not the datagaurd.
So for applying application patch I cant switchover the database.
I have to shutdown the primary database and apply failover to the standby database to apply patch.
Can you please tell how can I restore my standby database to actual primary after failover.
As our actual activity will be in 2 weeks time. We want to apply patch on saturday.
DR DRILL is on 8th nov.

Your earlier statement "Can you please tell how can I restore my standby database to actual primary after failover"
means something different from "SO have to restore from cold backup of primary database"
What you seem to want is a procedure to recreate the Standby from a Backup of the Pirmary. (ie FROM Primary TO Standby).
You haven't specified your Oracle Version. DG has been available since 9i (was even backported to 8i) but I will presume that you are using 9i
You should follow the same process as used for the first creation of the standby, except that you don't have to repeat some of the setup steps (listener, tnsnames etc)

Restored standby database from primary; now no logs are shipped

Hi
We recently had a major network/SAN issue and had to restore our standby database from a backup of the primary. To do this, we restored the database to the standby, created a standby controlfile on the primary, copied this across to the control file locations and started in standby recover and applied the logs manually/registered to get it back up to speed.
However, no new logs are being shipped across from the primary.
Have we missed a step somewhere?
One thing we've noticed is that there is no RFS process running on the standby:
SQL> SELECT PROCESS, CLIENT_PROCESS, SEQUENCE#, STATUS FROM V$MANAGED_STANDBY;
PROCESS CLIENT_P SEQUENCE# STATUS
ARCH ARCH 0 CONNECTED
ARCH ARCH 0 CONNECTED
MRP0 N/A 100057 WAIT_FOR_LOG
How do we start this? Or will it only show if the arc1 process on the primary is sending files?
The arc1 process is showing at OS level on the primary but I'm wondering if its faulty somehow?
There are NO errors in the alert logs in the primary or the standby. There's not even the normal FAL gap sequence type error - in the standby it's just saying 'waiting for log' and a number from ages ago. It's like the primary isn't even talking to the standby. The listener is up and running ok though...
What else can we check/do?
If we manually copy across files and do an 'alter database register' then they are applied to the standby without issue; there's just no automatic log shipping going on...
Thanks
Ross

Hi all
Many thanks for all the responses.
The database is 10.2.0.2.0, on AIX 6.
I believe the password files are ok; we've had issues previously and this is always flagged in the alert log on the primary - not the case here.
Not set to DEFER on primary; log_archive_dest_2 is set to service="STBY_PHP" optional delay=720 reopen=30 and log_archive_dest_state_2 is set to ENABLE.

NOW - before you say it - :) - yes, I'm aware that fal_client as STBY_R1P and fal_server as R1P are incorrect - should be PHP - but it looks like it's always been this way! Well, as least for the last 4 years where it's worked fine, as I found an old SP file and it still has R1P set in there...?!?
Any ideas?

Cant Restore I-tunes Library After Crash

Hello everyone, my computer crashed on monday but luckily I had backed up my library. I downloaded I-tunes and try to restore my library and the first disc did fine but when the second one tried to run I got an error saying "an unknown error occurred (-69)" Can some one please help me out?
Thanks Yall!
Dusty.

Hmmm, usually that unknown error -69 is related to syncing an iPod, not restoring backups from disc.
How did you do the restore? What version of itunes was it in? What version ofitunes are you using now?

Restore custom Illustrator actions after crash?

Hi. I just spent two days automating a large project with Illustrator CS6 actions. I suppose I should have expected Illustrator to crash at some point during this process but I didn't and, of course, it did. Upon starting Illustrator back up after the crash, I found that all dozen or so of my complex actions were gone.
I did a bit of googling and it seems that AI doesn't save these to disk anywhere; rather it just keeps them in memory until they're explicitly saved. That is, creating an action doesn't seem to actually store it anywhere. Is this correct? Anyone have any tips for recovering my work from this or am I SOL?
Thanks for any tips/suggestions/condolances.
(Edit: I'm using Illustrator CS6 on Mac OS X 10.8.2)

Until you tell AI to save the action, it's not physically saved anywhere.
That is rather a misleading statement, although it might be appropriate in this specific context (crash).
Unsaved Action sets have always been stored inside (one of) the AIPrefs files after quitting Illustrator. Otherwise they couldn't be available when relaunching the programme.
But as we are talking about a crash, that indeed may be bad luck.

Restoring read Gmail messages after crash

I had a kernel panic while in Mail and on restart Mail couldn't find any of my messages. I restored them by copying the Mail folder from my library them using Time Machine. I would like to re-download a couple days of messages from Gmail. I tried marking them as unread in my Gmail account and moving them to the inbox, but Mail wasn't fooled. It won't re-download them. I'd really rather not have to forward them to myself and sort by hand, which is the only suggestion I've had so far. Thanks.

Save the copy of the Mail folder. In the Mail window open this one account's Inbox, click on Mailbox in the menubar and choose Rebuild. Wait patiently for Rebuild to complete, and be aware that all messages in the list of messages will disappear for a short time. Should fix this.

Configuring a physical standby database in 9i

Hi all,
   SO: Solaris 10 SPARC x64
   DB: 9.2.0.6 x64
   I have a task of creating a physical standby database in a solaris 10 - Oracle 9.2.0.6 env. I am used to do this configuration on the 11.2 version of Oracle, and because of that i have some doubts regarding the possible different configurations necessary to do in a 9i Database.
   1) The main doubt that i have is regarding the RMAN use. I Would like to know if it is possible to restore a normal backup of my primary database into the standby database, and after that, apply the necessary archived logs to sync the standby with the primary? The controlfile that i would use would be the one created by the "BACKUP CURRENT CONTROLFILE FOR STANDBY" RMAN command. The RMAN script woulb be like the one below:
run {
allocate channel ch01 device type disk;
allocate channel ch02 device type disk;
allocate channel ch03 device type disk;
allocate channel ch04 device type disk;
restore controlfile from 'standby_controlfile.ctl';
sql 'alter database mount';
restore database;
recover database;
   2) The directory structure will be the same, so i think it is not necessary to use the SET NEWNAME and the DB_FILE_NAME_CONVERT/LOG_FILE_NAME_CONVERT, is that correct?
   3) Do you have any other considerations regarting the differences between a 9i and a 11g Physical Standby Configuration?
Thanks for your attention and pacience.

Hello;
On question 1 - See this:
http://docs.oracle.com/cd/B10500_01/server.920/a96566/rcmstand.htm
On question 2 - Assuming RMAN work then DB_FILE_NAME_CONVERT/LOG_FILE_NAME_CONVERT would NOT have to be set for the same directory structure.
On question 3 - double check this:

Creating standby database and replication of primary database in 9i

Hi,
We have a 9i database on Windows Server.Now recently we are planning to replicate the primary database to standby database once after creating the standby database.Can anyone guide me with the procedure or documentation with this . We were asked to do this without the data guard set-up. Please do help me regarding this ASAP.

Do I need to install oracle database 10gr2 before installing Oracle applica

I am new to Oracle application server. I am going to install Oracle application server 10g. From what I read, it looks like I need to install oracle database 10gR2 first on the SAME server? Is that correct?
If I do so, oracle_home will be point to where? to the Oracle application server home directory, or oracle db directory?
Thank you very much for you help.

hi,
Even i am new to oracle application server and had the same doubt that you have.
When you install Application Server there would be two tiers installed, application tier and middle tier, these tiers can be running from the same machine or different machines.
These tiers will have a meta data repository to store application server related data, this database will be installed along with application server.
It is upto you to install "oracle database 10gR2 " before or after installaion of application server, this will be an independent database which will have its own home, but after this installation you will have three homes, ex: infra_home,mid_home and 10gR2_home.
by default oracle_home is set to the last installation that happens so if you install the database 10gR2 after installing application server it will point to 10gR2_home, but if you install 10gR2 before and application server later then the oracle home will be infra_home(if both the middle tier and infratier are on the same machine)
you can always change the oracle home by using set ORACLE_HOME=path/to/oracle/home( in windows)
or export ORACLE_HOME=path/to/oracle/home (in unix)
hope this helps....

Autolog CDC could be one possible solution. It uses a feature of the downstream capture.
