Spfile restore question

Hi
I recently restored a database on a different server from a tape backup
the first step was restoring the spfile .
So I started the database in nomount, connected to RMAN with nocatalog ,set the DBID and run the following block :
*RMAN> run {*
ALLOCATE CHANNEL ch00 TYPE 'SBT_TAPE';
send 'NSR_ENV=(NSR_SERVER=bkpnyc02.ibasis.net,NSR_DATA_VOLUME_POOL=DBBACKUP, NSR_CLIENT=dcsdb, NSR_GROUP=RMAN_2_WEEKS)';
RESTORE SPFILE TO PFILE '/grid/u01/app/oracle/product/10.2/dbs/initdcsdb.ora' from autobackup;
SHUTDOWN ABORT;
that worked.
my question is - how did it work ?? how did RMAN, having no control file nor RMAN catalog - knows where is the location of the spfile backup on the tape ?
Again , this is a brand new server I am restoring into. no non-default parameters .
thanks
Orna

You have DBID in autobackup name, this is what I'm trying to show you. There is no way to configure autobackup to not contain DBID.
When you set DBID to 111222333 and client name for tape channel to client1 RMAN seeks for backups with 111222333 number in handle name taken from client1.
Is it clear?

Time Machine Restore Question

Hi,
I need to restore my Macbook Pro from my Time Machine backup as I cannot boot (gets stuck on the Apple screen with the wheel spinning and Disk Verify and Repair both fail). My questions is......if I do that will my bootcamp partition, which works perfectly, remain in place or will it be deleted / removed.
Thanks

your bootcamp partition will not be affected in any way.

ISE 1.2 backup restore questions

Hi all,
I have been looking at the backup and restore procedure for ISE deployments and have to say I have found the documentation to be somewhat confusing in general. Whilst I get the gist of it I have found numerous areas that are grey. This question is the first of many but here we go.
http://www.cisco.com/c/en/us/td/docs/security/ise/1-2/user_guide/ise_user_guide/ise_backup.html#pgfId-1073378
Based on that link to restore a failed primary admin node I am left wondering about the state of the licensing. In a deployment that has the licensing configured to utilise the UDIs of the primary and secondary node what happens after you have rebuilt the primary from the ground up?
As far as I am aware when you run up a new node the UDI changes meaning that the license detail is no longer correct - how does this affect the rebuilt node becoming primary again and do you have to rehost the license to reflect the new UDI?

Another question I have is about the restoration of monitoring data to a primary monitoring node that has temporarily failed. As per documentation it states that a manual backup should be taken from the secondary node and restored to the primary to essentially provide the missing events during the outage. I have a couple of questions about this process:
1. What happens when the primary monitoring comes back online - does it sync up with the secondary monitoring node effectively overwriting the events the secondary has or does it just continue on its merry way?
2. To restore data to the primary monitoring node do you need to de-register the primary before restoring the backup taken from the secondary and re-join it to the deployment or do you just restore from the primary admin GUI? As far as I can see this still means that there will be a hole in the data for the period of time it takes to restore from backup.

Exchange Server 2013 backup and restoration question

Good afternoon
I am wondering if I can pick people's brains here if that's not too much trouble.
I have recently implemented an Exchange 2013 environment with 3 servers (two multi-role CAS & MBX physical machines, and one further virtual CAS server). Everything is working correctly and mail-flow is fine. My question relates to backup and restoration
procedures. I am running a single Database Availability group with the two multi-role servers members of the this group and I have one Mailbox Database on the DAG, passive on one member and active on the other. Failover has been tested and this is functioning
as expected.
The backup environment I have implemented is as follows. I have utilized a separate Microsoft DPM 2012 server that runs a nightly Bare Metal backup on both multi-role servers with a retention range of 14 days and I have protected the DAG using DPM with a
nightly full-express backup and 4 hourly syncs on one of the multi-role servers. Furthermore the Mailbox Database is protected, again nightly with a copy-backup.
I am confident I know what to do should the mailbox database become corrupted or lost or need to be restored for one reason or another (it would just be a case of restoring the backed up mailbox database using DPM to a pre-created recovery database), what
I am not quite so sure on is what I would do should I lose one or both of the multi-role CAS and MBX servers (the third CAS I am not so worried about as it is not used for incoming mail flow from the internet and we really only use it for ECP as we did not
want to expose this to the internet). I wonder what process should follow to restore my Exchange servers (I know how to perform the Bare Metal recoveries using WSB) and what configuration would be required after restoring the Bare Metal backups.
I know this is a reasonably long question but if anyone has any advice for me I would appreciate it greatly in the unlikely event something goes horribly wrong with my Exchange environment.
Thanks in advance

Hi,
Yes, Most of the configuration settings are stored in AD. Mail data and personal related data are store in Mailbox DB. We just need to take consideration of these two points.

DB2 restore question

Hi!
Due to a unwanted batch input job we need to restore a R/3 system from prod to a sandbox system to have a reference system.
I have created a restore script with the brdb6brt tool to do a redirected restore, and it is currently creating table spaces in the database.
We are running on AIX v5.2 and DB2 v8 FP 11.
We have a full DB backup on disk and incremental backups on a networker managed tape library.
My question is:
If you restore with the parameter "incremental", is it possible to mark the DB as restored and start the rollforward process without applying the incremental backups on tape?
The documentation for DB2 leaves some space for interpretation, and I don't have the time to do wrong for this 1.4 TB DB.
Here are the examples from the documentation:
"Notes:
After successful completion of step 1, and before completing step 3, the restore operation can be aborted by issuing:
db2 restore db mydb abort
After successful completion of step 3, and before issuing all the required commands in step 4, the restore operation can be aborted by issuing:
db2 restore db mydb incremental abort "
Will any of these commands abort the restore so I need to restart the restore, or just exit the restore procedure so I can continue with rollforward.
BR Morten

Hi!
I will answer this post myself.
First read contetn in link: http://publib.boulder.ibm.com/infocenter/db2luw/v8/index.jsp?topic=/com.ibm.db2.udb.doc/admin/t0006070.htm
In addition:
Here the description of the command parameters for the restore:
CONTINUE
Specifies that the containers have been redefined, and that the
final step in a redirected restore operation should be performed.
ABORT
This parameter:
Stops a redirected restore operation. This is useful when an
error has occurred that requires one or more steps to be
repeated. After RESTORE DATABASE with the ABORT option has
been issued, each step of a redirected restore operation must
be repeated, including RESTORE DATABASE with the REDIRECT
option.
Terminates an incremental restore operation before completion.
Therefore if you allready have issued the "RETSTORE DATABASE NBP
CONTINUE" without any error, then the restore is finished.
You cannot do a continue manually because you are in another session
then the script (Therefore you get the SQL2008N).

Spfile restore from RMAN Tape backup to different server

Hi All,
First of all let me thank you to the forum from which I keep updating my knowledge on oracle.
I am having issues when trying to restore spfile from controlfile autobackup to different server. Problem and other details are below:
Target version : 10.2.0.2
Netbackup : 6.5.6
Taken the tape backup through rman on server ABC and trying to restore the spfile from controlfile autobackup to server XYZ. Tape backup has been taken today morning and trying restore now.
Both servers ABC and XYX have been added (as clients) to netbackup policy.
Below is the syntax I used for restoring spfile and getting error as mentioned.
RMAN> run {
2> set controlfile autobackup format for device type 'SBT_TAPE' to '%F';
3> allocate channel ch00 device type 'sbt_tape'
4> parms='ENV=(NB_ORA_SERV=Mediaserver,NB_ORA_CLIENT=XYZ)';
5> restore spfile to pfile '/oracle/product/10g/dbs/inittest.ora' from
6> autobackup maxseq 5 maxdays 3;
7> }
executing command: SET CONTROLFILE AUTOBACKUP FORMAT
allocated channel: ch00

Not sure where I am doing wrong. The same can be restored onto same host (I.E ABC) without any issues .
Request your help and guidance.
Thanks,
SSS

I don't know whether you can restore to a different server. The easier way should be
RMAN> restore spfile to pfile 'YOUR_PFILE_NAME' from autobackup;
then copy this to the new host.
Check this link
restore spfile to another host
Hope this helps

Using Lenovo's Enhanced Backup & Restore Questions

Hi all,
I am wondering if anyone has any experience in using Lenovo's Enhanced Backup & Restore.
My situation is that I am thinking of updating the firmware on my MyDigitalSSD 128GB mSATA SSD to the latest version. However, from what I read, the update will wipe the mSATA SSD. Also, at the moment, I have been backing up my C:\ to an external HDD weekly using Lenovo's Enhanced Backup & Restore software.
My question is if my steps below are workable and if the Enhanced Backup & Restore program will restore my system back to the latest backup?
1. Use Enhanced Backup & Restore program to backup the latest image of my system.
2. Update firmware on my mSATA SSD. All data will be wiped.
3. Use my Recovery Discs to restore the mSATA SSD to Lenovo's factory image.
4. Use Enhanced Backup & Restore program to restore the latest image.
Any comments, anyone? Thanks in advance!

You can only restore to the same hub, as the serial numbers have to match.

Backup/restore questions LMS 4.2

Hello,
I have several questions regarding data migration from LMS 3.2.1 to LMS 4.2.We will perform backup and restore procedure on new LMS4.2 server machine .
1. I am wondering what will happen with admin password aftrer restore, and all the other passwords in LMS. What will be effective? What will happen with database passwords?
2. Other thing is : LMS 3.2.1 is installed on D:\ProgramFiles\CSCOpx and the new LMS 4.2.1 is installed in D:\CSCOpx
Will there be problems during restore, because the paths on old and new LMS server are not the same?
3. When to perform the licensing? Should I apply license before restore? I think I would have to apply it before beacause customer has 300 devices and eval license iz for 100 only.
4. Does PI_CM license - Compliance Management License comes with the product? How do we get this license? I am aware that this CAAM is new feature in 4.2 version so I am not sure does the customer have rights on it. They have bought upgrade from 3.2 to 4.1 and they have valid support contract so we will go to 4.2 version.
Thanks!
Marija

Following are the answers :
1. LMS's user info and passwords are stored in cwpass file under NMSROOT\lib\classpath\com\cisco\nm\cmf\servlet, which is also
backed up with DB backup. Hence restore would bring all previous user names and passwords.
2. Ciscoworks has a mechanism which doesn't bothers the install directory. It sets environment variable as NMSROOT which is replaced by
the install directory and hence there should not be any issue. Please note that Inter-OS resotre are not supported.
3. You can apply the license anytime, but it is good to install it before backup restore, else the excess of devices, more than 100
will go to unmanaged state and will have to be brought back to managed state once lic is applied.
4. CAAM lic has to be purchased separately. You can contact lic. team or your accounts team for this.Till that time you can use it with its 60 days eval lic.

System restore questions

I'm with a HP Pavilion dv3-2150us
Originally shipped with Vista, and I got a free upgrade to windows 7 when it came out.
Now the computer is some years old, slowed down and a little crabby. I thought about restoring it,
starting with a fresh OS, surely it will make things work more smoothly. My questions are these:
1) If I run a factory restore - will I still have the recovery partition available? As I understand it format the hard drives - but does it keep the recovery files for a future recovery?
2)I guess it will recover the computer back to Vista. Is there a smart way to recover it straight back to WIN7? I Think I can find the upgrade disk got in the mail. Or am I forces to restore to vista and then upgrade again?
3)Will I need any Vista/Win7 activation keys to do this whole thing? Any other programs will need to be re-installed, but I am not sure I ever had an activation key for windows as it came with the computer.
Thanks a lot
Dvir

Hi,
Your Recovery Discs will return the notebook to it's factory condition ( ie with the Four Primary Partitions you have now ), no matter how you have partitioned the HDD in the meantime - in fact, when using the discs, there is no way to avoid this which is why it's important to back-up the content of any custom partitions as they will be erased by the recovery process.

IPad Restore Question

Hi Guys and Galls,
I'm just after a little bit of advice, I had an iPad for a few days and bought quite a few apps for it and had it backed up on my PC. I had to return the iPad for unforeseeable financial circumstances. So my question is when I get a new iPad in a few weeks how do I get the apps I bought for the old iPad onto the new iPad?
Second question, I’ll be changing my PC in a couple of months will iTunes just backup the iPad on my new PC or will I need to copy over the apps to my new PC from my old PC?
Many thanks

When getting your new iPad just connect it to your computer and restore it from your previous backup.

PSE 4 Restore questions, please.

I have a few questions on how the restore function works in PSE 4 (having never done it before):
1) I have a full backup on an external drive that dates to June '09. Looking in the backup folder, all pictures have Bxxx.jpg names. Plus there are MyCatalog.buc and backup.tly files. When I restore them, will the original folders and filenames be recreated?
2) During the restore process, will I be able to tell the system which drive/folder to restore them to?
3) If I have since created a new mycatalog.psa in PSE and added recent photos, when I restore my backup, will it append the restored photo's to that catalog, or completely overwrite it?
4) It's hard to explain but I have lots of duplicates, unnamed, misfiled, etc. photo's that I would dearly love to properly organize (my catalog has about 11,200 photo's in it). Should I do this outside of PSE4 and then re-import into a clean catalog (yes, and loose all my tags, etc.), or try to manage it all thru PSE? The reason I hesitate about the latter is, I'd need to click on each picture in PSE4 to see if it is not named properly, then dig further into properties to see if it is misfiled....a daunting task with over 11,000 pictures. Would appreciate your advice before I begin this project.
5) Somewhat unrelated question - I started to re-org my pictures earlier (before my crash) and found many w/ wrong date/time (metadata) associated. Up to this point, I did nothing outside the catalog (but have done a lot of moving, re-importing, etc., over the years). So, how is it that the date/time associated to a .jpg can change? Literally by years? Can you advise on what scenarios might make this happen?
Appreciate any advise you might lend. Thanks -
Christie

What a coincidence. I came to these forums because the same thing is happening to me in PSE 7, and I actually was doing a search on the green box around the photo and the flashing date when I click on a file folder and that led me to this thread. I have my Photoshop organizer file structure set up to match my Windows file structure. I use Photoshop to download all of my photos to folders labeled with the date the photo was taken. Then I typically rename the folder using Photoshop, and the matching rename shows up in Windows. If I move any files or folders, I do it through Photoshop Organizer. I have read the online manual and I *think* that I'm following the instructions, but I admit that I don't find any of it to be particularly intuitive. Whatever I'm doing wrong must be cumulative.
This has happened gradually, but now when I ask the Organizer to display the photos (I have everything checked to show in the 'View' menu), it displays only a fraction of them, and they are associated with the wrong folders. When I try to rename some of the folders, I get a message that says "The folder that you are trying to rename contains files that are not visible in the Organizer. Are you sure you want to rename this folder?" Yet, when I right click on the file in the Photoshop filetree and display the files in Explorer, then attempt to add them to the Organizer, Photoshop tells me that all of the files have already been imported. The only way I can see some of them in the Organizer is to search for them by filename, and I'm not talking about edited images, I mean the originals in the set. And I, too, have found photos (originals, not edits) that have had the date changed. Fortunately, I have under 1000 photos so I could erase the whole thing and re-import them and re-tag and caption everything, but I've spent hours and hours doing this already and don't want to have the same thing happen to me again.
At this point, I'm ready to just go back to organizing, rating, tagging and captioning my photos in Windows and using PSE to just edit them and create the occasional online album to share with family.

Randomly Pausing Audio Playback/Restoring Question

My iPhone 3G will on it's own, randomly pause audio playback (Pandora, iPod) when a 3.5 mm jack is plugged in, this takes any-wear from 10 secs to 30 mins, and this never happens when I use Apple OEM iPhone headphones. I went to an Apple store and the proposed resolution was to restore my iPhone as new. So my first question is: if I restore my iPhone as new, load music and a few apps on it and this does not fix the problem, can I restore my iPhone to the current state that has all my apps and data? My other question is, does anyone else have this problem?
Thanks!
-Mike

I don't have this problem.
But your question about restoring your phone to it's current state, yes. When you plug your iPhone into iTunes, right click on the phone in the column on the left and select "backup phone". (That is if iTunes doesn't automatically start syncing/backing up.) After that you perform a restore which erases the phones and updates to the current version. At that point, iTunes should prompt you to install the backup.

Win 7 Backup/Restore Questions

I have questions about Windows 7 Backup & Restore. From everything I am reading, it would appear that the program performs as advertised, but some of the traits I am witnessing just don't make any sense to me, and when it comes to Backup/Restore
(B/R), things need to make sense.
Q1: I have a machine that is configured with three (3) accounts: one is a privileged account (admin), and the other two are normal non-privileged accounts (acct1 and acct2 for reference purposes). I perform the backup from the admin account, backing
up the entire machine (all accounts). The backup completes without error. If I then Restore Files to view what was saved, I am shown the admin account, and acct1 as available to restore. Acct2 is not visible! Why not? Am I not
allowed to restore this account as admin? If it is a permissions issue, then why can I see and select acct1? If I logout of admin and login to acct2, and run B/R from there, the admin and acct2 backups are visible, but not acct1. So I know
the data got backed up, but why am I not able to see all the backup accounts when running as admin? If I had a machine with 15 accounts, does this mean I would have to login to each account to restore its files when rebuilding after losing a drive?
Q2: Backups are tagged by date. If I run B/R daily, it appears that the backup is retagged with a date range. If I wait a number of days to perform the second backup, I may get a second backup entry with the new date. What algorithm is
being used to determine when to extend a backup, and when to create a new entry? Is there a trigger that I can use that will force the creation of new entry, and not extend an existing entry, or vice-versa?
Q3: Everything suggests that with multiple backups, the oldest backup represents a full set of files, and subsequent backups are incremental. Exactly what is meant by incremental. I would expect this to mean that any file that has not changed
since the last time it was backed up would not be part of a new backup. Or stated the other way, any file that has changed since the last time it was backed up would be part of the new incremental backup. If I have 4 backups, will B/R examine all
4 to determine whether a file needs to be included in the new incremental backup (I assume so)? If I have 15 backups will B/R examine all 15 to calculate the new incremental (I assume so)? If I decide to manage space and delete the oldest backup,
will a subsequent backup operation resave all my old files that have not changed since the first backup but are now missing from the backup set (I assume so)? If so, then any space gained by deleting the original backup will disappear after the new incremental
completes. Would it be better to delete only the older incremental backups to free up space?
Q4: If I were writing this program, I would expect that contained in each backup is an index to all the saved files along with their dates of existence. I would have to scan ALL backups to create an index of ALL files with their respective save dates.
I could then compare the current file path and date with the name and date in the archive to determine whether the current file needed to be included in the new incremental. If this is the case, is there some point where deleting some of the older backups
will improve the overall efficiency of the backup operation by reducing the number of backups that need to be scanned to build the current backup file list? If so, what is a good rule of thumb for the number of backups to retain to preserve program efficiency?

Hi,
First question, I'm sorry for never heard this problem, I would made a test in our test enviroment, After that, I would provide the result at here.
For other questions , I would like to suggest you read the link below for some details about system backup.

Backup after restore question.

Hey everyone,
My question is if it is possible to ONLY recover the SMS history and contacts from a backup and nothing else. How can I do this? I really need to do a clean wipe of everything else but the SMS history and contacts.
Please help me and thanks in advance!

The restore from backup process is ALL or nothing. There is no way to do a selective restore of data. Contacts should be synced to a supported application on your computer, that makes it real easy to sync such back to your phone. Not syncing contacts & only storing such on your phone is asking for trouble.
There are third party software solutions that can extract data from your iphone backup, but none that I know of that can then restore such data back to a non-jailbroken phone:
