Restore only 1 tablespace to standby server.

Hello,
I would like to restore only 1 tablespace to a standby server.
This is what I was planned to do :
startup nomount of the standby server
connect with rman from the primary to the standby with :
rman target / auxiliary sys/xxxx@standby_SID
set until scn 4847169298;
restore standby controlfile;
restore tablespace xxx
But my question, do I need to specify something to skip the other tablespace ?
How will my controlfile know that this standby db only has this single tablespace and that the other tbs are not on this server ?
any help welcome,
Kristof

You will need, at a minimum,
SYSTEM
SYSAUX (if 10g)
the Undo tablespace (whatever name you have given it).
.. and the tablespace xxx that you want
If you use the controlfile, you'd have to take all the other tablespaces offline

Restoring only the tablespace from the database

How do we restore only a 'tablespace' from a Terabyte database without restoring the entire database.
ie... if a particular tablespace has been dropped from the database and we have the backup available for the database.
So, how do we go about it for restoring only that tablespace.

If you have a RMAN backup before dropping the tablespace then we can restore the tablespace by below method
It is a tablespace point in time recovery ,here we need to create a auxillary DB.
Recover a table/tablespace from Rman backup on same server:

1.u should have valid backup of the database before dropping the tablespace.
2.create the password file of target database.

How to backup only one tablespace in cold backup noarchivelog mode

Hi,
How to backup only one tablespace in cold backup noarchivelog mode
Reagrds,
Rushang

We have to restore all 50 GB database if we fail in scripts meanwhile to start again the data load.
Out scripts populater only two tablespaces.
That's why if i take backup of those tabblespace then i have to restore only those tablespace not whole database.

Reorganize tablespaces in Oracle standby server

Dear All,
Our current configuration is
SAP ECC 5.0
Oracle 10.2.0.2.0
HP/UX 11iv1
We have Oracle Data Guard installed and working. Since a couple of our SAP tablespaces are very fragmented, we would like to reorganize them using brtools. These tablespaces are large (300+ GB) and we don't have the downtime to do the reorganization in the primary server. I was wondering if we can do the following:
1.      discontinue applying archive logs to the standby
2.      open the standby database
3.      reorganize the tablespaces
4.      shutdown and mount the standby database
5.      continue applying the archive logs from step 1 on
I am not sure step 5 would work. The SCN would have changed during the tablespace reorganization.
Thank you very much,
Fong

> Also, since our primary server is production critical, we are worrying about some locking issues during the online reorganization. That is why we would like to do the reorganization in the standby server.
Stop worrying and learn how online reorgs actually works!
You've payed a huge bunch of money for a DBMS that allows online reorgs and now you don't want to use it because you are in fear.
And you are in fear because you don't seen to know but in doubt and uncertainty...
Bad place to be - especially if your system is so critical.
There is no way you can move your data on your standby size and then be able to re-synch the data with the primary site, since only physical standby is supported for SAP systems (that is block changes are transferred from primary to standby db - not SQL commands).
With online reorg you can actually do what the name promises - perform your reorgs online, while the whole application is fully up and running.
If you don't trust it (which is a good thing), then try it out on a test system before (you should practise it anyhow before you reorganize the production db).
regards,
Lars

Standby Server Problem

Hi,

Single license / Standby Server Preparedness

I have a production server with a Standard Edition One single CPU license. I need to be ready in case the server has a problem and I need to stand up a new server.
At what point is it required to buy another license?
Case 1:
Standby Server: Oracle is not installed.
Primary Server does level 0, level 1 backups to the Flash Recovery Area. The backups are copied the Standby server each night. Furthermore the archive logs are copied to Standby as they are created.
Recovery would involve, installing Oracle and then using rman to restore and recover.
Case 2:
Standby Server: Oracle is installed, it only has the sample schema and is shutdown.
Primary Server does level 0, level 1 backups to the Flash Recovery Area. The backups are copied the Standby server each night. Furthermore the archive logs are copied to Standby as they are created.
Recovery would involve, starting Oracle and then using rman to restore and recover from the FRA.
Case 3:
Standby Server: Oracle is installed, communicates to Primary via Net8, has a copy of the primary database, is mounted and applying archive logs throughout the day.
Primary Server does level 0, level 1 backups to the Flash Recovery Area. The backups are copied the Standby server each night. Furthermore the archive logs are copied to Standby as they are created. Standby applies the arcivelogs via .bat script.
Recovery would involve, applying the last archive log and opening.
I’m trying to find the fastest road to recovering to a new server without needing to shell out $5k for a license and another $1k per year for support.

>
I'm pretty sure doing any of my proposed solutions is of the developer license, as this a production environment. It seems like it a violation of the license to have Oracle installed on 2 servers even if one is shutdown.
>
That would be my opinion as well.
>
It's like Oracle requires us to install it on the 2nd server only when the 1st server it out of commission. I really don't know.
>
Still don't know why you don't have an image backup of the disk partition that Oracle consumes.
I have multiple OS's installed on machines in their own partitions. On Linux you can easily use the DD command to copy an entire partition, sector by sector, to a backup file. Restoring it takes only a few minutes even for a 20 GB partition. An Oracle-only installation is nowhere near that size.
I can restore the OS or an installed app in a few minutes from an image backup. This is really easy on Linux since there is no registry to deal with. At some point you need to start heading towards virtual disks.
Using Oracle's VM technology you just have a VM template (image) that gets deployed to a server. You only need the license for the servers you actually deploy to. So if a server goes down you redeploy the OS template to another server and keep right on trucking.
You should really look into VM and start getting familiar with it. It is a game changer.
The Oracle VM Templates main page is
http://www.oracle.com/technetwork/server-storage/vm/database-092479.html
They have a VM Templates for RAC also.
http://www.oracle.com/technetwork/server-storage/vm/rac-template-11grel2-166623.html
Using Oracle's virtual box you have plenty of pre-built developer VMs available for download
http://www.oracle.com/technetwork/community/developer-vm/index.html
And plenty of Oracle-provided articles about how to use VirtualBox and those templates
http://www.oracle.com/technetwork/articles/servers-storage-admin/howto-use-vb-templates-1695904.html
I have a single server that has multiple VMs running on it for different OSs including Windows XP. I rarely pick up any viruses because each system is in its own virtual machine. Periodically I just redeploy a VM template for XP and start fresh. Important files and page files are on on high-speed shared drives.
You are missing out on the revolution if you haven't ventured into the VM area yet.

Restore the dropped tablespace using RMAN?

Hello,
I have done a oracle tablespace re-org for PSAPPOOLD,PSAPPOOLI. Now I want to restore only the OLD PSAPPOOLD,PSAPPOOLI tablespace using TAPE backup via RMAN.
The probelm is I have dropped the old tablespace during re-org which is a part of the re-org. Is it possible to restore the dropped tablespace using RMAN?
My Oracle version is 9.2.05
if anyone has done this before, please share your valuable ideas.
I wrote the below script for the restore.
run {
allocate channel ch1 type sbt_tape;
startup nomount
restore controlfile; -
>(I guess,if I restore old control file, I might get old structure which help the restore of TB)
alter database mount ;
restore tablespace PSAPPOOLD,PSAPPOOLI;
recover tablespace PSAPPOOLD,PSAPPOOLI;;
release channel ch1;
Thanks,
Arjun

Hello Arjun,
why would you want to do this?
What is is you want to achieve by this action?
BTW: it's not possible to do that.
Check [Performing RMAN Tablespace Point-in-Time Recovery|http://download.oracle.com/docs/cd/B10501_01/server.920/a96566/rcmtspit.htm].
You want a "Tablespace point in time recovery" (TSPITR) for a dropped tablespace and that is just not possible with RMAN.
So, the easiest way for you to get this tablespace back would be to restore and recover the database to a different host.
Ah, while we're at it: using RMAN outside the BRTOOLS is not supported by SAP - so you better be a wiz with it because there won't be much help in case anything does not work.
regards,
Lars

Move Publisher backup to new server( Cold Standby Server) ?

We have CUCM cluster consist of 1 publisher, 4 subscriber and have installed a new node like another cluster's publisher(with diferent ip address from existing publisher) . When existing publisher goes down we will move publisher backup to new server and change publisher ip address to new server on existing subscribers.
is it posible ?
Our aim is using new server for publisher down issue.(like cold standby server but diferent ip address from existing publisher)
Or is there any better way to install publisher backup on on branch? When publisher goes down we will use the new server like publisher.

Hi
Re: NTP... you can have multiple NTP servers assigned, and only the primary NTP server is used for license MAC generation. As such, I would:
1) set the primary NTP server to be the real NTP address you want to use. This will not be accessible when you build the server with the old servers' IP.
2) set the secondary NTP server to an accessible NTP server. I do this by setting up NTP on the server you serve the SFTP backup file from. I use Meinberg NTP if this is a Windows box, it's free.
That way you can build the server (primary NTP not accessible, but secondary is so it's fine). Then after the restore, change IP address and it will start using the primary NTP server.
I presume deployment type refers to product and role .e.g. a CUCM Publisher, not a CUC server or CUCMBE publisher.

Steps to Make STANDBY SERVER..................

hi
1. can any body tell me the steps to make SAP standby Server.
2. if our live SAp production Server fails then how can we up the standby Server.
3. & after this when we make SAP Server again then how can we make this server
in its actual position from standby Server.
thanks & best regards.

Hi all,
I dont think cluster is the solution for this. Because the requirement of DR server is different otherthan cluster environment.
cluster is the concept to recover the primary database in hardware failures etc. And DR concept is for disaster recovery situations.
Clustering concept is for quick resolution without any delay, only if your database is available.
And steps to configure DR site.
1) Install one DR server with same SID and same platform
2) Take a full online/offline backup of primary database.
3) Restore the same in to DR server
4) Create standby controlfile on primary database and copy the same to DR
5) Mount the DR database into standby mode
6) recover the database, it will prompt you for next sequence of archive logs.
7) Strart copying of archivelogs from primary to DR
Let me know if any wrong from my side.
Regards
Nick Loy

Standby Server

Hi All
I have oracle 9i DB.
I want to make a (standby server) in diffrent location, which is a mirror of my current server for the first time,
then I want to send a batch to update it once aday.
in case of any damage of the current server I will connect to the (standby server).
what is the right way to make this plan?
I am thinking of use RMAN , but how ?!?!?!?! (any help doc)
Are there a better way ?
Another Question :
I use the (Archive log) in my DB, for now I am using EXP from my backup,
I don't think that we need Archive log once we use EXP for all data, How to stop working with archive log?
thanx in advance

I don't think that we need Archive log once we use EXP for all dataYeah, go on with NOARGIVELOG mode if and only if you want to loose data. And don't reply you don't want, because the only way to preserve data is to have a backup and archivelog files from backup time to "now". If you're trusting export for your backups I'd advise you to get back to TFM, for your data's sake.
I am thinking of use RMAN , but howIf you want to create a standby database, just look there: http://download-west.oracle.com/docs/cd/B10501_01/server.920/a96566/rcmstand.htm#1004466
And use DataGuard for the synch of the databases. Or maybe are you planning to clone the whole server? If so, did you take in account the time take by a restore in case the main server crashes? etc?
DR is not an easy stuff. If you describe what you want to achieve, we will be able to give advice, not if you only ask widely open questions!
Regards,
Yoann.

We have a RAC DB which is used by more than 20 applications. One schema for each application and one tablespace for each schema.
We have a schema with 130gb in size. All Objects in this schema use a single tablespace MCS_DATA.
This weekend we are applying some changes involving DDL, Code and Data .Usually we take an expdp backup of the schema before the activity starts and later if something goes wrong with script deployment we'll revert to old state by dropping the schema and doing an impdp from the expdp backup.
Question1.
Can we do an RMAN tablespace only backup and if something goes wrong with script deployment can we drop the schema and the tablespace and then create an empty schema and then restore from the tablespace backup ?
Question2.
If the above is possible , can you explain how it is going to work out because we are essentially plugging (restore,recover) in a tablespace to the database. Any potential problems ?
Question3. If the above (Question1) is possible, will restore/recover of this tablespace require a downtime for the entire DB ?

Tom;
If you are talking about RMAN TSPITR then yes you can. See - Purpose of RMAN TSPTIR in Backup and Recovery User's Guide E10642-03.
The problem with TSPTIR is bulk. You need a lot of disk space to create a copy and then data pump the information out and back in. I just tested this on 11.2.0.3 and its slow. RMAN created a script which produced an AUX instance and did the data pump, but I had clean up afterwards. If it errors out you can have an AUX instance hanging out in the background.
For TSPTIR you will need an area on the disk to server as an auxiliary destination large enough to hold what you are recovering plus the SYSTEM, UNDO and TEMP tablespaces.
I would probably look at Transportable tablespaces as a possible option too.
http://docs.oracle.com/cd/E25054_01/backup.1111/e10642/rcmttbsb.htm
E10642-03 has a section for recovering a tablespace in chapter 2. The Tablespace must be offline, but the database can be up.
This uses "restore tablespace" and "recover tablespace" commands. You would perform this type of recovery when you are say missing a datafile. You can recover any tablespace except SYSTEM and UNDO with this.
Data Pump might be an option too, but given your tablespace size I would have worries about recovery time. Oracle lets you set compression
and a limit to each file produced.
expdp TABLESPACES=YOUR_DATA dumpfile=DATA_PUMP_DIR:ts_dumps_%U.dmp LOGFILE=DATA_PUMP_DIR:ts_dumps_log.log parallel=2 filesize=10G compression=ALL
Given the size of your database a better option might be something like Data Guard as your recovery time would be brutal.

UCCX 8.0 SNMP notification to report failover from active to the standby server?

Does any know the UCCX 8.0 SNMP notification to report failover from active to the standby server? (The specific notification.)
ftp://ftp.cisco.com/pub/mibs/v2/CISCO-VOICE-APPS-MIB.my
I see this in the MIB.
cvaModuleStart NOTIFICATION-TYPE
OBJECTS   { cvaAlarmSeverity, cvaModuleName }
STATUS    current
DESCRIPTION
        "A cvaModuleStart notification signifies that an
        application module or subsystem has successfully
        started and transitioned into in-service state.
        This notification is working in conjunction with
        the cvaModuleStop notification to notify the start
        and stop status of a particular application module."
::= {ciscoVoiceAppsMIBNotifications 1}

Attached are two files:
cad-ecc-viewer.html
This is a template HTML document which dictates how the pop up will look and what data fields are available.
cad-ecc-viewer.vbs
This is the Windows Scripting Host file which you run from a CDA workflow, and you pass it the values of the call data, it then launches an instance of IE and loads the above template.
By default the code is setup to use the following data from the call, but can be modified to work with more, less, or different data:
Customer Name
Customer Status (like Premium, or Platinum)
Customer Number (like an account number)
Customer Phone Number
So when you specify the VBS file to run in CDA you need to pass those variables in that order.
The CDA should expect the VBS file on the root of C:\ by default, and the VBS file expects the HTML Template on the root of C:\ also.
I have only tested this on UCCX 7x and IE 8x. Use the code as a guide to your own solution, that suites your business requirements.
EDIT: I see that this does not work on my Win7/IE9 system, so I will spend some time updating the code for Win7/IE9 and I'll let you know how it goes.

Hi,
I've seen that, if the following message persists for a long time, then it is an ERROR.
FAL[client]: Failed to request gap sequence GAP - thread 1 sequence 17857-17863 DBID 3371425568 branch 681431456 FAL[client]: All defined FAL servers have been attempted.
The possibility is that log shipping of 17857 is stuck. It is not stuck because of any network disconnect, as it is in the case you mentioned. It is probably due to the following.
The parameter LOG_ARCHIVE_DEST_1 on standby is set as L:\ORACLE\A30\ORAARCH\A30ARCH\ARC and STANDBY_ARCHIVE_DEST is also set to L:\ORACLE\A30\ORAARCH\A30ARCH\ARC. When a GAP is identified, standby database tries to pull the missing files FROM PRIMARY, and the in turn when you enable standby destination on primary (log_archive_dest_state_2 = enabled), it starts shipping logfiles on its OWN.
When such a situation occurs in a system when archived logs are generated at a high rate, it can happen that the file which standby is trying to pull is being pushed/already pushed by primary database. Then a conflict arise, and standby deletes the file and tries to pull it again...this may go on in a loop. (because the locations are SAME).
When i had this issue, I maintained different locations for LOG_ARCHIVE_DEST_1 and STANDBY_ARCHIVE_DEST on standby database. After this is done, you will find that the logs shipped by primary are written in STANDBY_ARCHIVE_DEST. The file written in this location will be used by the standby database only when you do a managed recovery. If you are doing a manual recovery by issuing the command RECOVER STANDBY DATABASE; then, the stanbdby database will check if the file exists in LOG_ARCHIVE_DEST_1.
The point is, when there is BIG gap, then you have the option of doing the following procedure.
1. On the primary database keep LOG_ARCHIVE DESTSTATE_2 = enable
2. On the standby ALTER DATABASE RECOVER MANAGED STANDBY DATABASE CANCEL.
3. Copy the missing archive logs sequence from the primary to standby's LOG_ARCHIVE_DEST_1 and perform manual recovery on standby untill the gap is over.
4. issue the command ALTER DATABASE RECOVER MANAGED STANDBY DATABASE DISCONNECT to start managed recovery. ( This will use the files present in STANDBY_ARCHIVE_DEST ).
Hope the above procedure helps.
Note: If the GAP is not that big and you see that last applied log is advancing, then conflict is not there...standby will automatically fill the GAP. But it is advised to maintain different location for the parameters i mentioned.
Regards,
Anish

Duplicate of Database - Restore of Specific Tablespaces using RMAN

Hi, is it possible to perform a duplicate of a large database to a point in time (from tape) but only restore specific tablespaces, this database uses partitioned tables for a week of data, each set of partitions have their own tablespace.
Thanks.

Use can use the “SKIP TABLESPACE” option of RMAN DUPLICATE to bring only the tablespaces you want.

Error in standby server

The standby server not receiving archivelogs continuesly . Scenario : in 10 files transmission,database transmitting only 7 or 8 files. remaining files i am copying maunally & then resolving the gap sequence .when i see alert log file in standby server I am geting an error like follows.what should i do?
