RMAN backup using OSB too slow
Hi all,
We are exploring Oracle Secure Backup in our environment as legato networker alternative. But RMAN backup in OSB is very slow due to sbt wait event(sbtwrite2). it can backup 5GB/hour. We think this not normal behavior. we have checked network throughput between media server and client server. It can send 50 GB data by 30 min.Could you please help us to resolve the problem.
Thanks,
Hello,
What OS do you use? This is a Windows OS or UNIX ? Above all, we need more information about the Hardware and the others plans that ran in this environment.It can be also competition from other jobs.
Kind regards,
Bruno Reis

RMAN backup uses more space than actual DB size
Hi All,
Yesterday, we have configured the RMAN backup for an RAC db in HP-UX. The total DB size is 82GB
but the RMAN took around 250G space for backup and the backup failed. The oracle db is 10.2.0.1.

What can I do for backuping oracle10g in oracle9i rman successfully ?The recovery catalog schema version must be greater than or equal to the RMAN client version. Therefore, you should create a 10g recovery catalog in the 9i catalog database. Check the RMAN Compatibility Matrix for more information.

RMAN Backup using Rman Catalog
Hi
can we take backup of oracle9i database using oracle10g RMAN Catalog?
Thanks
With Regards
OHI guess this is related to backward compatibility support principle. Target database's controlfile and RMAN catalog is synchronized and different version may have different structure and feature. When we need to completely restore an Oracle instance from backup, RMAN catalog must be able to support target database, and it may not be possible if RMAN catalog version is lower than target database. I hope I get the message across.
Pls anybody correct me if I am wrong -
Calling VB Executable using HOST too Slow....
Hello Friends,
I have one form containg one program unit, Program unit has one cursor,which contains Employee Id and Email Id, Based on Employee ID Report is generated in HTML Format.Next I am Calling VB Executable using HOST which Sends generated report through mail based on EmailId. I am passing Report File and EmailId using Command line arguments.
But,It takes too much time to return back to Form from VB application ? It quickly exits VB applications but then it takes too much time to return back to Oracle Forms ?
What can be the reason ?
Adiexactly, I think we were too impatient.
It seemed working well after deleting half of snapshots, but just next day it occurred again.
of course the system is maintaining snapshots just half of the original, but it became slow because unknown reason.
we've tested something like following because we doubt that zpool was related to the too low performance.
case 1 : 1 zpool, 1*500MB mkfile, 50*100MB mkfile at any time
case 2 : 20 zpool, 1*500MB mkfile to ONE zpool, 2~3*100MB mkfile PER zpool at any time
case 3 : 1 zpool, just 1*500MB mkfile
in case 1 and 2, 'at any time' means that 100MB mkfile processes were maintained to restart when finished again and again.
we estimated the time to write 500MB for each case.
case 1 result : about 6 minutes
case 2 result : about 16 minutes
case 3 result : about 4 seconds
in the case 1, the test was harder than our real-world situation, but it took only 6 minutes.
our system log told us that writing about 1GB took more than 50 minutes!!!
do anyone know why the tests above result like this?
and our zfs performance is still problem.
please reply anything about our situation.
we'll of course test the ARC size. thank about this.
thank you. -
Hi,
I have a Production Database (10204) running on HP Unix (B.11.11).
Daily morning 6AM, a full RMAN backup runs. The db size is only around 225GB. But it takes 4.5 hours to complete.
The syntax which I use is given below.
RMAN> run {
allocate channel ch1 type "sbt_tape";
allocate channel ch2 type "sbt_tape";
allocate channel ch3 type "sbt_tape";
send
'NB_ORA_CLIENT=jjcprd04-back.backup.ncsus.jnj.com,NB_ORA_POLICY=JJCPRD04-RMAN';
backup
format 'bk_%s_%p_%t'
(database include current controlfile);
sql 'alter system archive log current';
backup
format 'arch_%d_%s_%p_%t'
(archivelog all delete input );
Is there a way to increase the speed of this backup? Currently the backup is way too slow as it takes 4.5 hours to copy 225GB of data!
Thanks!I'll start by stating that backups directly to tape are generally quite slow.
I'd still recommend moving to disk backups though... and just archiving it to a tape...Hi Jony,
You can of course backup to disk. Thats a common solution. But you have to deal with space more than everything. In addition to that backing up to disk does not free you from moving/copying your data - depending on your backup strategy - to a long-term storage.
So you have two different and not conjunct backup operations: the rman backup itself and the job which backups the rman area to another media.
In recovery cases you might end up with RMAN requesting older backupsets which are not on disk anymore. This will most probably lead to recovery failures and manual intervention which is not desirable in recovery scenarios.
Another point is the control of the data flow. Backing up via a MML (i.e. "to tape") does not necessarily mean "to tape". Instead it means "to the backup software" which is responsible for managing the backup data. Common scenarios involve backing up the full backups via SAN directly to tape and backing up the archivelogs or incremental backups over LAN which will be stored by the backup software on a hard disk and later copied and/or moved on to tape. The data flow (to SAN / to disk / whereever) is solely controlled by the backup software.
The advantage here is one continuous backup and restore job. The backup software deals with "where is my saveset located" and requests automatically the needed tapes or disks in recovery scenarios. This makes recoveries far more flexible and comfortable.
Regarding the throughput i have set up a rather large OLTP database ( 12 TB currently) which is backed up with EMC Networker. Full backups are written via SAN directly to tape. The average speed with four LTO-3 drives is approx. 550 MB/s (the tape drives compress the data in hardware; the database itself is text-only and seems rather good compressable). I guess thats not too bad.
you can also compress the BACKUPSETS (this generates a little more CPU but less network IO)He said he is on HP-UX. These kind of CPUs tend to be not that fast. Using compression is an option worth testing but there is another point to test when doing compressed backups: The RESTORE TIME.

RMAN backup fails using OEM with no output error
I am trying to do a weekly automatic full backup of a database in noarchivelog mode using RMAN in Enterprise Manager. Every time I submit the backup job (even if I try to do an immediate backup) the job fails almost immediately. When I Iook at the job output for the failed attempt, it says that there is no output for the job. I believe I have all of the preferred credentials and priveleges correct. Does anyone have any ideas as to what the problem could be or maybe where I can find an error log for rman to get a better explanation of the error?
Thanksplease check in metalink.....

Execute RMAN Backup in debugmode
Hi
We are running RMAN Backup using perl script.
We need to run the RMAN backp in debug mode. How we can do this by passing parameter in the perl script itself.
PS. As we dont need to change the perl script or editing the RMAN script.
ThanksI don't know how your script is being executed, but you could pass in the debug parameter with the command you use to launch RMAN:
rman target / debug trace='c:\bk_trace.trc' -
Hi All,
I need details about some diagnostic test regarding RMAN backup on my instance.
The following are the current configuration of details:

Earlier the RMAN backup used to take 20 -23 hours, now for the last 2 months, it has started taking 40 hours.
We want to identify the reason behind the increase in time.
Please let us know methods that we can use to diagnose the root cause.

RegardsThis is a NetBackup configuration issue. The client doesn't have a policy for your monthly job/schedule. I would recommend comparing the setup of the daily/weekly vs. the monthly job.

How can I make Time Machine use the ethernet cable to Time Capsule instead of the wireless connection? Wireless is too slow; has been taking 40 hours to create an initial 142 GB backup.
Plug in ethernet .. in the computer.. turn off wireless.

Hi
I have oracle database (11gR1) 64 bit installed on Windows 2003 R2 64 bit server. MY DB size is almost 152 GB and its running in archive log mode. When i run RMAN online backup , Its taking too much time almost it has taken 22 Hours and still its running , I am not sure why it is consuming this much time ..
I am using below RMAN script ...
run {
allocate channel ch1 type disk;
backup FILESPERSET 32
format 'F:\RMAN_BACKUP\%d_t%t_s%s_FULL' tag Full_DATABASE_07_july_13
(database)
CURRENT CONTROLFILE SPFILE;
SQL "alter system archive log current";
backup FILESPERSET 200
format 'F:\RMAN_BACKUP\ARC_%d_%s_%t'
(archivelog all);
release channel ch1;
Kindly help me and whats wrong in this please tell me . Also tell me if any other information needed ..

Vikash Jainhi, Till now RMAN backup not completed for single time so i cant tell how long it takes.
I tried with parallelism 2 also but it is also not working.
CONFIGURE DEFAULT DEVICE TYPE TO disk;
# backup goes to disk
CONFIGURE DEVICE TYPE disk PARALLELISM 2;
# three channels used in parallel
CONFIGURE CONTROLFILE AUTOBACKUP ON;
#controlfile and spfile take backup automatically
CONFIGURE CHANNEL 1 DEVICE TYPE DISK FORMAT 'F:\RMAN_BACKUP\%d_t%t_s%s_FULL' MAXPIECESIZE 10G; # 1st channel
CONFIGURE CHANNEL 2 DEVICE TYPE DISK FORMAT 'F:\RMAN_BACKUP\%d_t%t_s%s_FULL' MAXPIECESIZE 10G; # 2nd channel
run {
allocate channel chnnel1 type disk;
allocate channel chnnel2 type disk;
backup database tag Full_DB_090713_With_CH_02;
SQL "alter system archive log current";
backup archivelog all format 'F:\RMAN_BACKUP\ARC_%d_%s_%t';
release channel chnnel1;

RMAN backups running slow with Catalog , Running fine using control file.
I am facing a weird scenario
RMAN backups are running fine with Control file but are failing using Catalog
There are other databases configured on the same catalog and they are running fine leaves us to suspect this is issue with Database.
Can you please suggest what need to be checked in such scenario
DB: 11.2.0.2
OS: Aix 6.1
Catalog : 11.2.0.2Hi,
Basically its not only with backups, simple list incarnation also taking a lot of timeDo sql tracing on your catalog session and target db session while running the 'list incarnation' command for your problem dbs and a normal dbs.

Tycho
