Backup tech_st using tar??

we have EBS R12.1 on Linux system. I remember ORACLE instructor told us when backup TECH_ST using "tar". the command must include "h" like "tar cvfh ...".
I have been tried this "tar cvfh" and untar it using "tar xvf" or "tar xvfh". I found link is gone and change to 'physical file".
My question is using "tar cvfh " to perform backup or clone is right way?
Thanks.

The topic of backup of apps tier has been discussed before. Pl use the search option to find threads like these - Re: should i backup just the db or the apps too?
You can use either tar or copy to perform a backup. Always remember to test recovery using the backup files - this is the only way to verify that your backup is good and what steps you need to perform in case of a real recovery scenario.

Using tar with zip for Datafiles backup on windows machine

Dear all,
We have R12 e business suite instance on windows.
I was implementing cold backup for this. Unfortunately i am not a windows guy.
I do have MKS tools installed on my windows machine, which contains the tar command.
Can i use tar -cvzf <bkp>.tgz <location of datafiles> for this?, My main concern is, is it going to harm the source like corruption etc..
Thanks

If MKS tools are supported under Windows it should not corrupt input files whether input files are Oracle database files or any other Windows files.
You could try instead to use RMAN for cold backup if you have already RMAN experience:
- RMAN does not backup empty blocks
- RMAN can also compress backups
- RMAN is fully supported on Windows if corresponding Oracle version is certified on your Windows server.
See an example of cold backup for database running in NOARCHIVELOG mode in http://docs.oracle.com/cd/E11882_01/backup.112/e10642/rcmquick.htm#BRADV90059.
If your database runs in ARCHIVELOG mode just backup your database online: http://docs.oracle.com/cd/E11882_01/backup.112/e10642/rcmquick.htm#i766544.

Wow the GUI looks great.
Sadly, it's of no use to me as I personally am satisfied with rsync. But, I am sure others will find it useful.
Edit: By the way, you should put qt qt4 (whichever version you are using (I am blind )), in the PKGBUILD depends array.

Ow can I use my time capsule as a time machine backup without using it wirelessly and not as a wireless router?

How can I use my time capsule as a time machine backup without using it wirelessly and not as a wireless router?

It is better to have the TC as part of the main network in bridge. You do not need to run wireless.
If you want to use the TC plugged in by ethernet and still use wireless for internet, that is possible but the setup is rather more complicated.. the computer must not get confused about which device to use as a gateway or dns server.
See info in this thread on setting this up.

I need to add.. a USB drive would be cheaper, faster and more reliable. It is really poor use of a TC.

I bought an external hard drive for backups to use with Time Machine, but however when I try to connect it with the other windows laptop it doesn't work ? intact it doesn't work on any other device except my MAC ?

Do not worry about it.
Time Machine needs that your external drive is formatted in HFS+, or better known as "Mac OS Extended (Journaled)". This filesystem is used by Apple on Macs and Windows cannot read or write drives formatted with this filesystem, being this the reason why all your devices do not read the external drive except your Mac.
You can only use your external drive to make Time Machine drives. If you store anything different, you may damage the Time Machine structure, so it is better not to use it as a drive to store other data. Instead, get another external drive to do it or create a second partition on the external drive formatted in FAT32 by using Disk Utility > http://pondini.org/OSX/DU3.html FAT32 can be read by Windows PCs

Oracle 9i TEMP tablespace backup problem using RMAN!

Oracle8/8i whole backup is ok for our backup software(using RMAN without RC database), but for Oracle 9i, I get following error messages when backing up temp tablespace.
1. RMAN-20202: tablespace not found in the recovery catalog
2. RMAN-06019: could not translate tablespace name "TEMP"
I check some views of Oracle9i, and know some changes happen for temp tablespace in 9i, but how to deal with this problem. Any idea, please!

In 9i RMAN does not restore temporary datafiles. Instead, you should create them after your restore. I believe that Oracle is going to make a change to this in the next release of 9i and have RMAN create the temporary files. You can view the temporary datafiles @ v$tempfile.
I believe RMAN doesn't restore temporary files because they are locally managed and not in the control files. RMAN reads the controlfile of the target database to obtain info about backups, datafiles, etc.
Hope this helps.

Using tar command to copy faster

Hi,
I want to copy the apps directories and subdirectories to another location on same machine for cloning purpose.
I know this can be achieved using tar command.
Will you pls send me the tar command to archive and copy at the same time using pipe "|" .
Thanks,
Dnyanesh

Hi Funky,
Permissions are assigned based on uid, not username. When you unpack the tar file with the 'p' option as root, the files will have the same uid on the target system as they did on the source system. In this case, preserving permissions for 'root' should not be a problem. The uid for root (0) does not usually change. The complication is with the uid values for non-root users.
As far as preserving the uid for non-root users (like oracle or applmgr)...mostly I just try to keep these in sync across my systems as much as possible. :) For example, although the applmgr user on my production system is 'applprod', and on my test system is 'appltest', they both have the same uid (1003). That way, when I unpack a tarball from my production system on my test system, all the files that were owned by 'applprod' show as being owned by 'appltest'.
In your example, if user 'xxx' on production and user 'yyy' on the clone server had different uids (for example, 1003 and 1004), the easiest thing to do is to try changing the uid of user 'yyy' on the clone system:
usermod -u 1003 yyy
This will only work, of course, if there is no other user on your clone/target system with uid 1003. :-)
If you do have another user on your target system with uid 1003, then when you unpack the tar file on the target, your files will definitely have the wrong owner. You can still change that without touching root-owned files by using chown to change just the files owned by the "wrong" user:
chown -R --from wronguser correctuser $ORACLE_HOME
If your Linux doesn't support the --from syntax for chown (I primarily use SUSE/SLES and don't have my Redhat VM handy to check), you could also use find:
find $ORACLE_HOME -user wronguser -exec chown correctuser {} \;
Again, the point of the chown and find commands is that they'll leave the files that are supposed to be owned by root untouched.
Sorry for the long post, I tried to go for comprehensive instead of brief this time. :-)
Regards,
John P.

What's the best way to backup DFS using DPM 2010?

We setup DFS on two Windows 2012 R2 and they are hosting files. What’s the best way to backup DFS using DPM 2010?
1. When doing data backup, do we backup both dfs01 and dfs02? Or just backup one of them?
2. Beside the data, what do we need to backup?

Protecting Data in DFS Namespaces
Backup files and BRM of dfs01 and dfs2 for minimaze traffic.
If dfs01 and dfs02 have good channel width that use DPM to only protect a single “copy” of the data located on a server-specific local path.

Can i roll forward cold backup taken using os command

i have cold backup of db which is in archivelog mode ( backup taken using os level cp command )
and arch logs from after backup was taken.
can i restore db and rollforward using the archive logs?

Hi mseberg,
In the first article you point to ( http://www.reachdba.com/showthread.php?532-Oracle-Database-Manual-Backup-and-Recovery]), the author wrote this:
a) when Online redo logs backup is there.,
and after that, he wrote this:
b) when Online redo logs backup is not there.So, I don't understand what is written in that article: it seems to me that it's often mentioned that there should be no redo log backup.
Please, could you clarify about this idea of redo log backup in the first article you pointed to ?

"Backup failed" using Time Capsule

Hello, trying to back up a Macbook using Time Capsule, keep getting the message that backup failed, even when I attach with MB to TB with an Ethernet cable.
Anyone have any idea where I could begin to start looking for a solution?

Hi James,
Have you tried erasing your Time Capsule disk? If it's the initial backup, it could be that you have a corrupt sparsebundle file. Go into AirPort Utility > Manual Setup > Disks and select and erase the internal disk. Then try your backup again using an ethernet cable and see if that works.

I am trying to confirm the time at which a particular backup occurred using an external hard drive that I have since misplaced. Although time machine lists the backup times for some backups, it does not list them for all. Can someone help?

I am trying to confirm the time at which a particular backup occurred using an external hard drive that I have since misplaced. Although time machine lists the backup times for some backups, it does not list them for all, including the one in question. Can someone help?

Okay, I've sussed it. I saw a link to another discussion that hadn't turned up in any of my searches before I posted the question above.
My Tosh HDD was formatted to FAT 32 and therefore would not be backed up by Time Machine. I removed all data from it - nightmare as I hadn't enough space to put it on the macbook HDD, but, after trawling through numerous photos and deleting rubbish for hours, I finally made enough space and copied all data across. Then, after clearing the data from the Tosh HDD, I used disk utilitity to reformat it to Mackintosh OS Extended. Chose the option without kournalling because I'm not baking up onto this disk and so don't need it - according to some other discussions I found.
When it was done I check on time machine in system prefs and once I selected options, I was able to remove it from the excluded from backups list. Hey presto. Now I'm moving my photo library and my music library onto the Tosh HDD and my macbook should start to breath again. Hurray.

Synchronous multimaster replication Backup strategy using RMAN

Hi all,
I am using synchronous multimaster replication. my question is backup strategy has to perofirm in all the master site or only in any of 1 mastersite? what all problems will encounter in RMAn backup in my scenario please help me out with your suggestion
nagaraj.K
[email protected]

You ask: "I want to configure backup strategy using RMAN. any one can help me that"
And the answer is clearly no we can not.
An RMAN backup strategy depends on your SLA (Service Level Agreement) with your customers that you didn't post. What is your down-time window? What is your skill set?
You ask: "How to configure for RMAN Incremental backup?"
Read the docs at http://tahiti.oracle.com for your version (which you didn't mention).
You ask: "What will be backup space and there size ?"
We have no idea. Are you going to create an image copy or a backup set? Read the docs and learn the difference. Are you going to turn on compression? Are you going to back up only changed blocks? We don't know.
You ask: "how to manage growing online archiving files?"
Again we can't help you without knowing your SLA. How many MG/GB are they? What period of time do you need to retain them to meet your SLA? When you figure this out back up to tape those you don't need to keep on the server.
You ask: "how to manage growing data and there disk space?"
This is one we can answer: BUY MORE DISK! That was easy.
You ask: "How we can give good performance our CPU and memory?"
Do you really expect that we can with zero knowledge of your environment, your version, your application, etc. distill into a few short paragraphs the collective wisdom of Cary Millsap, Jonathan Lewis, and the rest of the Oak Table Network membership?
Of course we can not. So what you need to do is buy Cary's book, Jonathan's book, and take their classes.
You ask: "we need keep all archive log in backup files or we need to remove old archive files?"
Remove the old ones after being absolutely sure you have a good backup.
You ask: "where we can take backup tape drive,SAN,disk removable hard disk? which one is better?"
No one solution is better than the other. They are all adequate.

Getting Error "too large to archive" while using Tar

Dear All,
I am getting below error while trying to use TAR to acrhive multiple files in one file:
<FileName> too large to archive
The file is of size 2 GB (there are other files with same capacitiy but i am not getting any error for them). Here is waht i am trying to acheive:
(1) Create one tar file from all files in a folder (using tar)
(2) compress the tar file (using compress)
(3) copy the compressed file to the tape (using tar)
One more question, when i use compress (or gzip) command, it create comressed files but original files are not preserved. For example; if i use compress for files a.txt & b .txt it creates a new file (say ab.Z) but removes the files a.txt and b.txt. Is there any option (or any other command) using which i can comress the files without getting them removed?
Thanks in Advance.

Dear Robert,
Thanks for your help. While trying to create tar file using gtar i am now getting below error:
No space left device
So appearantly i don't have enough free space on my file system on which i am trying to create two questions:
(1) Is it possible to compress the tar file resulting from gtar in one command (tar file creation + compress). I don't want files get removed after compression.
(2) Can we directly write to Tape Drive using gtar? Will the size of file resulting from gtar will be same as that of total size of all files or it will be less?
regards,

Backup procedure using RMAN for 11i Instance

Hi,
we have 11.5.10.2 instance
Node 1 = Application Tier ( 11.5.10.2)
Node 2 = DB Tier ( 9.2.0.7)
as of now, we are taking daily cold backup of both instances.
we want to implement RMAN online backup for DB and take cold backup every week end only.
so, what are the best procedures for implementing RMAN for 11i Database.
Please share your experience, if you have anybody implemented?
which one you prefer in RMAN backup ( backupsets or copy option or backupsets with compressed option) interms of performance.. our db size is 60 GB only.
we apply apps tier patches very rarely . so we want to take RMAN online backup for DB daily and take cold backup for entire apps and db in the week ends.

Hi,
This time, i am going to implement for Oracle 11i Database. thats why, i need you guys advice regarding 11i Database.Well, the same is applicable to 11i/R12 databases. You just need to configure RMAN the same way you configure it on any standalone database.
If you have implemented any where RMAN, can you share, how you are taking RMAN backup? I can share the scripts we use for backup using RMAN. If you are interested, let me know and I shall send it by email.
if we want to clone, are you cloning the TEST instance with RMAN backup or using cold backup.We use both, depends on the time frame of the cloning task and whether it is possible to use cold backup for cloning or not.
Please have a look at the following notes, it should be helpful.

Backup Failure using OEM (Oracle 9i)

Backup Failure using OEM
I have oracle 9i (windows 2000 server)
I tried to make a fullbackup using OEM, it gives me NO error messages
I got result file with 890 MB (my Db is not huge),
but when I go back to the JOBs in OEM I found the status of the job FAILED
I tried to do the same thing using incremental backup level 0, but I got the same result
any Idea why the job didn't complete successfully
thanx in advance

Here is the deal.
I need to be able to work in the OEM for my class. (Oracle DBA in Training) It is a significant part of my grade to be able to find the required help through forums like these to help me get the backup/recovery process to work through the OEM. My books deal with the OEM in a Win2000 Pro/Server environment, and don't take into consideration the variances in XP Pro. My install works great, other than I am receiving a "Fail" on my OEM Backups under Jobs. It further explains that I do not have the proper permissions to perform the backup job that was created. My instructor is completely hands off when it comes to help. So if anyone has run into this problem and been successful in fixing the problem without using a different utility. Please let me know.
Thanks in advance,
Vic
