Using old file system backup for Cloning

I have taken an off-line backup of Oracle 11i (11.5.10.2) 15 days ago. Before taking backup of file system , I verified that all the latest Rapid Clone Patches are applied. No changes or patch work in APPL_TOP or DB has been done since that backup. Now I need to do cloning of this instance, how I can use this backup for Cloning.
Rapid Clone scripts create and generate some files/directories so I am not sure whether my Old backup of file system will work or not. What is the best way to use old backup for cloning , also what are the file and directories in addition to the old backup of file system which I need to copy to Target System.
Thanks for reviewing and suggestions.

Samar,
If you have run preclone before backing it up, your backup should be valid for cloning.
2.1 in the cloning doc has to be in the backup.
These doc's should clear out yours doubts on cloning.

How to recover DB2 using offline file system backup.

Gurus,
I had a problem with my BI PRD's database. 1 of my BI consultant accidently deleted some important 2010's data. We've try recover online database backup of BWP into BWQ and retrieve the missing data. However the backup retention period was expired and we dont have any available online backup now.
Only hope is my offline file system backup which backup the whole file system of BWP ONLY.
My question:-
Can i restore the file system (offline backup) into BWQ and rebuild my DB2 in BWQ. Please enlighten me.
Thanks,
Devan.

Hi
You can do it .The file system backup image can be mirroed into production system and by making using of "db2inidb" utility you can restore the whole database.

Warming up File System Cache for BDB Performance

Hi,
We are using BDB DPL - JE package for our application.
With our current machine configuration, we have
1) 64 GB RAM
2) 40-50 GB -- Berkley DB Data Size
To warm up File System Cache, we cat the .jdb files to /dev/null (To minimize the disk access)
e.g
// Read all jdb files in the directory
p = Runtime.getRuntime().exec("cat " + dirPath + "*.jdb >/dev/null 2>&1");
Our application checks if new data is available every 15 minutes, If new Data is available then it clears all old reference and loads new data along with Cat *.jdb > /dev/null
I would like to know that if something like this can be done to improve the BDB Read performance, if not is there any better method to Warm Up File System Cache ?
Thanks,

We've done a lot of performance testing with how to best utilize memory to maximize BDB performance.
You'll get the best and most predictable performance by having everything in the DB cache. If the on-disk size of 40-50GB that you mention includes the default 50% utilization, then it should be able to fit. I probably wouldn't use a JVM larger than 56GB and a database cache percentage larger than 80%. But this depends a lot on the size of the keys and values in the database. The larger the keys and values, the closer the DB cache size will be to the on disk size. The preload option that Charles points out can pull everything into the cache to get to peak performance as soon as possible, but depending on your disk subsystem this still might take 30+ minutes.
If everything does not fit in the DB cache, then your best bet is to devote as much memory as possible to the file system cache. You'll still need a large enough database cache to store the internal nodes of the btree databases. For our application and a dataset of this size, this would mean a JVM of about 5GB and a database cache percentage around 50%.
I would also experiment with using CacheMode.EVICT_LN or even CacheMode.EVICT_BIN to reduce the presure on the garbage collector. If you have something in the file system cache, you'll get reasonably fast access to it (maybe 25-50% as fast as if it's in the database cache whereas pulling it from disk is 1-5% as fast), so unless you have very high locality between requests you might not want to put it into the database cache. What we found was that data was pulled in from disk, put into the DB cache, stayed there long enough to be promoted during GC to the old generation, and then it was evicted from the DB cache. This long-lived garbage put a lot of strain on the garbage collector, and led to very high stop-the-world GC times. If your application doesn't have latency requirements, then this might not matter as much to you. By setting the cache mode for a database to CacheMode.EVICT_LN, you effectively tell BDB to not to put the value or (leaf node = LN) into the cache.
Relying on the file system cache is more unpredictable unless you control everything else that happens on the system since it's easy for parts of the BDB database to get evicted. To keep this from happening, I would recommend reading the files more frequently than every 15 minutes. If the files are in the file system cache, then cat'ing them should be fast. (During one test we ran, "cat *.jdb > /dev/null" took 1 minute when the files were on disk, but only 8 seconds when they were in the file system cache.) And if the files are not all in the file system cache, then you want to get them there sooner rather than later. By the way, if you're using Linux, then you can use "echo 1 > /proc/sys/vm/drop_caches" to clear out the file system cache. This might come in handy during testing. Something else to watch out for with ZFS on Solaris is that sequentially reading a large file might not pull it into the file system cache. To prevent the cache from being polluted, it assumes that sequentially reading through a large file doesn't imply that you're going to do a lot of random reads in that file later, so "cat *.jdb > /dev/null" might not pull the files into the ZFS cache.
That sums up our experience with using the file system cache for BDB data, but I don't know how much of it will translate to your application.

Linux Cluster File System partitions for 10g RAC

Hi Friends,
I planned to install 2 Node Oracle 10g RAC on RHEL and I planned to use Linux File system itself for OCR,Voting Disk and datafiles (no OCFS2/RAW/ASM)
I am having SAN storage.
I would like to know how do i create shared/cluster partitions for OCR,Voting Disk and Datafiles (common storage on SAN).
Do i need to install any Linux cluster file system for creating these shared partitions (as we have sun cluster in solaris)?
If so let me know what versions are supported and provide the necessary Note / Link
Regards,
DB

Is possible control tape library slot 1 - 10 for file system backup

hi ..
i am new to osb , i just install and setup osb , i have a question as below , hope expert can help me
env: testing
rhel 5.5
tape library with 20 slot
file system backup
1. is possible osb only use slot 1 - 10 for file system backup ? amanda can control slot x - slot y for the configuration .
2. how do i label the tape for slot 1 - slot 10 by obtool ? how to control osb auto load the tape for next backup ? where to check the log say that next tape is tape-02 ?
thanks ..

hi dcooksey
how do i use list for a tape drive...for example, if you want tape drive A to only use slots 1-10 from obtool or webtool ?
becoz i new to backup solution & osb ( i always use ghost or acronis to clone the image ) , my thinking as below , pls correct me if i am wrong
slot 1 - 10 for daily backup
slot 11-16 for full system backup
slot 17 - 20 reserve ( this tape only use for full system backup before perform any application upgrade patches , )
daily backup mon - fri ( 2 week ) ( no backup on saturday and sunday ) , server application offline
full system backup friday ( 1 , 14 on calendar ) every 2 week perform full system backup after daily backup completed
for upgrade application ,
perform full system backup after daily backup , then release the server to application team to perform upgrading .
so how to set my media family for the above setting ? the slot configuration is control by media family ?
hope you can help ...

OS File System Backup

Hi,
Apps: 12.1.3
DB-11gR1
OS - RHEL 5.6
How i can take OS file system backup manually?-
which is the best mothod?
I know, we can use tar?
could anyone tell me which is the best method..
Thanks
KSV.DBA

In addition to the link mentioned above, do you have to rely on free solutions, or do you have a budget for a solution?
You can perform a complete OS level backup of your Oracle database when it is shutdown, or put the database into online backup mode, but need to review the Oracle documentation for limitations. The tools of choice for Oracle is RMAN, which does not require extra logging or backup mode.
You can use tar or rsync if you prefer to backup data to a shared storage through NFS or use tar to stream the data to an attached tape drive. There is plenty of information and tutorials on how to perform incremental backups on the web, and here tar incremental backup

Error 64 is being returned which is simply "the network name is no longer available".
There can be a number of reasons for this from SMB compatibility issues (2003 servers wont support SMB2), to the expected and actual computer name of the boxes don't match (tries to authenticate with server.tld.com when the actual name is srv-01.tld.com and
you just put a C-name in). I'd start from the top: Try opening said share from the Primary Site server as that's the box doing the work. Verify the IP and computer name is legit and that no one has played ACL games between the two systems (remember
RPC only initiates/listens on port 135 but established connections are up in the dynamic port range).
At the end of the day it's an issues "underneath" SCCM, and not an SCCM problem specifically.

Help needed. I have a 3TB external hard drive partitioned into 1TB's. I used one partition as backup for the main computer hard drive. But now it is greyed out as shown in the disk utility and its name changed, i dont know how that happened, i tried verifying and repairing it but had no luck. I also tried mounting and unmounting it but still no solution. Anyone to help please?

Looks bad. I would strongly advise backing up the stuff on the other two partitions as soon as possible in case the rest of the drive goes wrong.
Beyond that, Disk Utility has limited abilities to repair disks, DiskWarrior uses a different approach and might, emphasis might be more successful. It has certainly done the job for me in the past when Disk Utility could not.
