OEM online backup still running since 4/5

We are at oracle 10.2.0.4. We are running online backups from Oracle Enterprise Manager. I noticed yesterday that the backup was still running from 4/5. I decided to let it try to finish last night but today it is still showing that it is running. I have tried to stop it but using the stop process button from the job status. On that page it shows stop pending now but all other pages that show status says job is still running. Anyone have any ideas on how to correct this and get back to normal operations again?

Do you have enough space were the backup is stored ?
Are you using a MML ? How large is the backup ?
Did you check your backup reports in OEM>Aviliability>Backup Reports ?
Does it show completed.
You may have to kill the rman session and restart backup job.
This is a loooooong time for a backup to run.

DB backup still running, but in DB13 already status "Finished with errors"

Hi,
firstly, I am not regular DB administrator, so please be patient with me.
On 5.4.2010, 20:00 started on our server regullary planned online complete DB backup. Now (runing for more than 39 hours - DB size is only 300GB and last time, when it successfully finished, it takes less than 12 hours) I see in DB13 this backup with status "Finished with errors", but in SM37 this job is still with status "Active" so it seems to be running. On HDD where backup should be stored is created file with size 0 B. In job protocol and program protocol are only standard messages, nothing indicates that there is any error. OS is Windows Server 2008.
Program log:

Anybody have idea what is doing there?

Thanks Adrian,
in DB50, DBAHIST has following record for this backup:
04-05 20:00:40 20100405200040 sda D01      DATA             9999 20100405200040
so it is still active. But when i launched DB50, there appears popup with question
Do you want to branch to the "Open Alerts" display ?
when i choose Yes, alerts are displayed, and there are some records like this
07.04.2010     14:50:08     D01     MaxDB Monitoring: D01     Last Backup     Last Complete Data Backup Return Code     ACTIVE     0002 - ERROR
i dont know if it means anything...
Also in table SDBADSDB is following record:
1     20:00:00     20100216134109     D01     20100405200000     20100405200038     ALLNC     sda     20100405200040     20100405200040     9999          Update task ADA_INSERT_SDBADSDB 01
=> EXT2 contains "Update task ADA_INSERT_SDBADSDB 01"
So I think only opening CSN message is only applicable here... but how to do it and what exactly is CSN message (like I said, I am not regular administrator...)?
And also I have found another strange issue - although file with DB backup has still 0 B, free space on that HDD is still shrinking, but no sizes of directories are increasing... in numbers - all files on that HDD (including hidden and system files) have 663 GB, but in properties of this HDD is that 1.06 TB is used - so the difference is cca 400GB (what is 2x more than previous complete DB backup and +100GB to actual DB size...).

Offline & online backups????

Hi all,
Why are the advantages & disadvantages of offline & online backups??

Hi Ravi,
Joydeep has described it very well.
Just to add a bit:
If you are wondering what happens to the online redo log files while the online backup is running:
<i>During online backup, BRBACKUP does not backup the online redo log files. Instead, BRBACKUP generates online redo log switches so that all the online redo log files written during the online backup are copied into the archive directory. These offline redo log files then need to be backed up, since an online backup is consistent only in conjunction with these redo log files. The BRARCHIVE program backs up the offline redo log files.</i>
So the idea that during an online backup some redo files might be missed, is explained from the above paragraph.

Loukas

UDB online backup runs forever

Hi!
I started an online backup last Friday. Until now the backup is still running.
Seems it is because of some network issue but we dont know exactly what is wrong.
We want either
1) kill the backup
or
2) restart the server.
We have tried to kill it but it is still running.
If we re-start the server, perhaps we will do something before we can start the DB.
Please help advise what we should do before we can re-start the DB. It will come back by itself
with the server?
UDB9 on AIX.
Thanks!

Jennifer,
you can interrupt a running backup like this:
Find the application handle ID via db2 "list applications show detail" or "db2pd -db <dbname> -applications" by searching for the string "performing a backup".
Force the corresponding application: db2 "force application (<application ID>).
Here what I have tested on my machine:
coe6p001:db2zwn 6> db2pd -db zwn -applications
Database Partition 0 -- Database ZWN -- Active -- Up 0 days 00:01:14

Getting error while running script for online backup

Hi,
I am running a script for online backup but ended up with an the below error.
*ERROR* [Backup Worker Thread] com.day.crx.core.backup.Backup Failed to create temporary directory
Please help out in resolving this.
Thanks in Advnace.
Maheswar

Hi mahesh,
If you are using backup feature from crx console, I mean http://localhost:4502/crx/config/backup.jsp I can say that we had also some problems with this functionalities.
First off all what you need to check are the permissions, because when you check a source code there is line which creates a File object using a path specified by you to make a backup of repository.
File targetDir = new File(req.getParameter("targetDir", listDir.getParentFile().getAbsolutePath()));
You need to have sure that the proper read write access has been granted for this path.
Another issue is that maybe there was already prepared some hotfix if you are using CQ5.4. Please refer to the following link:
http://dev.day.com/content/kb/home/Crx/CrxSystemAdministration/CRXOnlineBackup.html
and also to this one:
http://dev.day.com/content/docs/en/crx/current/release_notes/overview.html which contains a hotfix number #34797 which was applied to backup.jsp file.

After closing firefox, if I decide to go back online it says firefox is still running. I have all windows closed. I have to restart my computer before it will let me go online again.

If I go offline and later decide to go back online the error message says the firefox is still running even though all windows are closed.

*Wait a bit longer before reopening Firefox to give Firefox more time to close completely.
*Use "Firefox/File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit") to close Firefox if you are currently doing that by clicking the close X on the title bar.

Since installing yosemite my computer/screen blacks out, but still running

Since installing yosemite last week, my computer/screen blacks out, but still running. I have since rebooted everything, started from scratch and utilizing my external drive transferred all files/apps back. Did not help, in fact it is getting worse. Computer screen blacks out every 5 min or so and have to power up again. Also, continue to get Java message updates even after all have been updated over and over again. Any suggestions? Thanks!

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

Hello
The previous contributor is correct, the profile is usually read from ORACLE_HOME. I have never seen this error linking to the Oracle client directory, please double check the following
Ensure that your envirionment variables are correctly set ORACLE_HOME, DIR_LIBRARY
Brtools are always installed on the DB server and can be called from any application server. if you are scheduling from DB13 on the application server, what is the connection setup? RSH, RFC, standalone gateway?
If using a standalone gateway, it must be installed on the DB server, please refer to oss notes #446172, #1025707

Online backup via BRTOOLS

Hi there!
I am planning to implement an online backup using brtools. When I did the testing, I noticed an error that prevents me from completing the backup. Hope anybody can help me. It seems that there is an error with the compress command but I cant seem to understand why. Below is the entire log of my backup. Btw, Im using ECC6 and Oracle Database 10g.
Thanks in advance.

Hi Scott,
Thank you for the quick reply. However, I have another thing to bring up. I created an exact replica of this instance to a separate server for my online backup testing. I used mksysb for my rootvg and created a backup of my datavg and restored it to the new server. To my surprise, my online backup worked. Im currently running it so that I can upload the log in this thread. I checked on the version of the brtools and they are both of the same level. Also, I forgot to mention that I've been using offline backup via brtools since last year. It was only now that Im trying to implement an online backup. Would this problem still be caused by brarchive patch 18?
Thanks in advance!

How does recovery work after an online backup

Hello,
While trying to conceptually understand how backup and recovery works, I came accross a question concerning hot (online) backup.
This is a conceptual question (I am trying to understand how things work), it is not a "how should I proceed/ what should I do step by step" question.
As far as I understand, an online backup of a tablespace can be performed by copying the OS files making up a tablespace while the database is up and being used (i.e. transactions are modifying data in the database). Before the copying of the OS files starts, the Oracle RDMS must be notified that an online backup is being taken via "ALTER...BEGIN BACKUP" (such that some additional information is written to the Redo Log, which may be required for subsequent recovery using the online backup). During recovery the Oracle RDBMS uses the copies of the OS files together with the online and archived redo logs in order to reconstruct all committed transactions and it further uses the UNDO tablespace to rollback open (uncommitted) transactions.
Thinking about this, it seems to me, that in order for this to work in all possible scenarios the undo information from the time the backup was taken may be required. Therefore backup of the UNDO tablespace should be taken as well (see the explanation for this assumption below). However browsing the internet (including the Oracle online documentation) I did not find any statements concerning the backup of the UNDO tablespace when an online backup is taken. Moreover I couldn't figure out when exactly such a backup of the UNDO tablespace must be done, to ensure that the database can be recovered in all scenarios.
I believe that undo information from the time the hot backup was taken may be required e.g. in the following scenario:
Assume we are taking a hot backup of a given tablespace, i.e. we are copying all OS files that make up this tablespace, while the database is potentially being used. Let D1 be one of the datafiles in our tablespace and let transaction T1 modify datafile D1. Let transaction T1 further be uncommitted while the copy of datafile D1 is being made and let (at least some of) the changes from T1 be included in the backup copy D1' of D1 (because DBWR has already written the modified blocks at the time they were being copied to the backup). Let transaction T1 be rolled back after the copy is completed. D1' will thus contain modifications from T1, while D1 will not.
Now some time later the datafile D1 is lost. When recovering D1 from the copy D1', the (archived) redo logs will be applied to D1'. Before that, transaction T1 should be rolled back in the copy D1', because modifications from T1 must not appear in the recovered version of the database.
I do however not understand, where the information to rollback transaction T1 exactly comes from. It may still be in the current UNDO tablespace. I do however assume that rollback information is not kept in the UNDO tablespace forever. I see three possible answers to this
(a) There are some requirements which I missed so far to backup the UNDO tablespace whenever a hot backup is made.
(b) Since the Oracle "RDBMS" has to be notified that an online backup is being done, it might store all relevant undo information (e.g. write it to the redo log) when the tablespace is put in backup mode.
(c) There are situations when recovery is not possible due to "missing old UNDO information".
Answer (b) seems the most plausible to me. I did however not find any confirmation of this and if (b) really is the answer, I would be interested to understand what information is stored where by the Oracle RDMBS and how it is used for recovery.
To summarize I have the following questions:
(I) Is there any requirement to backup the UNDO tablespace together with an online backup of a tablespace, and if so, where is this stated in the Oracle documentation?
(II) What mechanisms ensure that uncommitted transactions can be cleared from the online copy of a tablespace (potentially a long time after the copy was taken)?
(III) Do you know any links (Oracle documentation or other online resources) explaining these datails?
Thank you for any hints and answers
kind regards
Martin

Its a highly technical question and I can be completely wrong due to my very less knowledge but I would attempt to answer still. Hope I say something sensible so bear with me.
As far as I understand, an online backup of a tablespace can be performed by copying the OS files making up a tablespace while the database is up and being used (i.e. transactions are modifying data in the database).Correct. But it would depend on the tool you are going to use to do so.Using o/s level commands like CP and all would require you to manually copy the files to the backup location. Using RMAN, it would be lot easier and RMAN would take care of everything.
Before the copying of the OS files starts, the Oracle RDMS must be notified that an online backup is being taken via "ALTER...BEGIN BACKUP" (such that some additional information is written to the Redo Log, which may be required for subsequent recovery using the online backup). Again, this is a requirement only in the case of user-managed backup . In that case, because of the fractured block issue , its important that the corresponding older information/image of the buffer is also copied in the redo stream and that's done when the begin backup command is used. Using RMAN, this is not needed as RMAN can read the consistent image which it would store in the backup piece, exactly in the same way in which select request is fulfilled by oracle for a dirty buffer which is yet to be made consistent.
During recovery the Oracle RDBMS uses the copies of the OS files together with the online and archived redo logs in order to reconstruct all committed transactions and it further uses the UNDO tablespace to rollback open (uncommitted) transactions.Correct!
Thinking about this, it seems to me, that in order for this to work in all possible scenarios the undo information from the time the backup was >taken may be required. Therefore backup of the UNDO tablespace should be taken as well (see the explanation for this assumption below). >However browsing the internet (including the Oracle online documentation) I did not find any statements concerning the backup of the UNDO >tablespace when an online backup is taken. Moreover I couldn't figure out when exactly such a backup of the UNDO tablespace must be done, to >ensure that the database can be recovered in all scenarios.The reason that its not a must to do so is that if the transaction is yet active, there is no way that Oracle would overwrite the Undo information of it, even if you may come after 100 years, it would be there. The Undo segment would mark those blocks as active undo blockswhich contains the information of that transaction whose status within the transacton table of that undo segment is still marked as active. So its there all the time in the undo tablespace. Now, for an instance, let's assume that the undo is not there as well( it would be but let's assume), the changes made to the undo segment's blocks are also recored in the redo as its just a change happening to any other segment like EMP,DEPT except with the difference that its not done by you but by oracle. So using that information, in the future , if there would be a need to replay those changes, necessary information to do so can be brought up from the redo blocks stored in the redo/archive logs. Yes, if there would be pending transactions that would require Undo information to get them rolled back and you have lost Undo tablespace and have no backup of it , you wont be able to bring back the database as it would be inconsistent and oracle would not let you to do it. In that case, you may require to use hacks to get it up and that would be really tricky situation.
(I) Is there any requirement to backup the UNDO tablespace together with an online backup of a tablespace, and if so, where is this stated in the Oracle documentation?As I said above, it must be there if you are anticipating loss of Undo tablespace. If you have lost it, you would need a backup and all the archive logs and redo logs to recover and get it back to the point where the current database is . Rest, oracle would take care as it would reapply the redo contents of the undo segments over the undo segment and get it consitent.
(II) What mechanisms ensure that uncommitted transactions can be cleared from the online copy of a tablespace (potentially a long time after the copy was taken)?As I said , pending transaction's undo is never overwritten by Oracle. Its always kept and marked as active undo . Only a transaction end would make it elgible to get overwritten and that too won't happen immediately(undo_retention would kick in) .
(III) Do you know any links (Oracle documentation or other online resources) explaining these datails?I have to see if its there some where step by step mentioned and I shall update the reply once I shall find the link. Hoep someone else in the meantime finds it .

Database open fails after online backup recovery

Hi Friends
We are trying to set up an additional server using the online backup of our DEV server. We have been following SAP Note 549828 for the same. Having restored the online backup, the open database failed.
To resolve the same, in accordance to SAP Note 549828, we created a backup control file with success using the command
create controlfile reuse set database DEV resetlogs noarchivelog
However on issuance of the command
RECOVER DATABASE USING BACKUP CONTROLFILE UNTIL CANCEL
we run into an error as to
ORA-00279: change 794638222 generated at 10/25/2007 12:43:20 needed for thread 1
ORA-00289: suggestion : /oracle/DEV/oraarch/DEVarch1_9766.dbf
ORA-00280: change 794638222 for thread 1 is in sequence #9766
Specify log: {<RET>=suggested | filename | AUTO | CANCEL}
ORA-00308: cannot open archived log '/oracle/DEV/oraarch/DEVarch1_9766.dbf'
ORA-27037: unable to obtain file status
SVR4 Error: 2: No such file or directory
Additional information: 3
ORA-01547: warning: RECOVER succeeded but OPEN RESETLOGS would get error below
ORA-01194: file 1 needs more recovery to be consistent
ORA-01110: data file 1: '/oracle/DEV/sapdata1/system_1/system.data1'
We even manually copied the file system.data1 from the source to the target server but to no avail.
Also the SQL command
SELECT FILE#, CHANGE# FROM V$RECOVER_FILE
displays a different change# for system.data1 while it is showing same number for all other datafiles.
Please advice at the earliest as we are struck. Points awaiting their master.
Regards
Lokesh Gupta

Some inputs addition to Erics comments
The problem is you dont have archives ie Offline redo logfiles in correct location.
/oracle/DEV/oraarch/DEVarch1_9766.dbf Here DEVarch1_9766 is archive file which is misssing from location /oracle/DEV/oraarch. To recover DB you need Archives generated during hot backup.
Generally these steps willl give you desired result.
select * from v$logfile;
We normally switch the log files to the number of log groups that exist
alter system switch logfile;
create a Backup directory to hold our hot back datafiles and Archives
When the backup is complete check the backup location to see if all the files are available. We could now either FTP the same to the other system or copy over these files to another location in case of cloning on the same system.
Copy over all the files to their respective filesystems and directories and then edit the file that was created using the backup controlfile to trace. Copy that file to the remote system and edit it accordingly.
check that all the files are in the right location and edit that information in the control file
Once the controlfile is run successfully and you get the statement processed, we can start applying the archive logs that we have moved to the archive log destination directory as per the init<sid>.ora file.
do a recover of the database to its consistent state
recover database using backup controlfile until cancel;
The create control file command only changes the structure of the database and the SID name, the header of the datafiles still hold all the required information. The above command would ask you to input the archive log file names one by one to do recovery or you could choose the AUTO option. Once the recovery process is complete, open the database with the resetlogs option

I have a Macbook Pro 15" that is three and a half years old. Although it has slowed a bit, it still runs well and runs every program I need. Any tips for how to keep this old computer running well and in good health?

I have a Macbook Pro 15" that is three and a half years old. Although it has slowed a bit, it still runs well and runs every program I need. Any tips for how to keep this old computer running well and in good health?
I have a 250 gig drive and try to keep at least 100 gigs unused at all times, 4 GB 667 MHz DDR2 SDRAM memory, back up with Time Machine and CrashPlan, and have OS X 10.7.3.
This was my first Mac since an old Apple II GS. After that I used PC's and got really good at reformatting, replacing drives, reinstalling, defragging, resolving software conflicts, etc. Since switching back to Macs (five in my extended family now), I haven't had to do any of those things. So, although, the cost is three times as much, the aggrevation has been ten times less.
I'm retired and living on a fixed income and would therefore like to keep this computer running as opposed to constatntly upgrading.
That said, any tips?
Thanks
It does have a crack on the left of the screen case about 3/4'' up from the bottom. I've posted that as another question.

Kappy's Personal Suggestions for OS X Maintenance
For disk repairs use Disk Utility. For situations DU cannot handle the best third-party utilities are: Disk Warrior; DW only fixes problems with the disk directory, but most disk problems are caused by directory corruption; Disk Warrior 4.x is now Intel Mac compatible. Drive Genius provides additional tools not found in Disk Warrior. Versions 1.5.1 and later are Intel Mac compatible.
OS X performs certain maintenance functions that are scheduled to occur on a daily, weekly, or monthly period. The maintenance scripts run in the early AM only if the computer is turned on 24/7 (no sleep.) If this isn't the case, then an excellent solution is to download and install a shareware utility such as Macaroni, JAW PseudoAnacron, or Anacron that will automate the maintenance activity regardless of whether the computer is turned off or asleep. Dependence upon third-party utilities to run the periodic maintenance scripts was significantly reduced since Tiger. These utilities have limited or no functionality with Snow Leopard or Lion and should not be installed.
OS X automatically defragments files less than 20 MBs in size, so unless you have a disk full of very large files there's little need for defragmenting the hard drive. As for virus protection there are few if any such animals affecting OS X. You can protect the computer easily using the freeware Open Source virus protection software ClamXAV. Personally I would avoid most commercial anti-virus software because of their potential for causing problems. For more about malware see Macintosh Virus Guide.
I would also recommend downloading a utility such as TinkerTool System, OnyX 2.4.3, or Cocktail 5.1.1 that you can use for periodic maintenance such as removing old log files and archives, clearing caches, etc.
For emergency repairs install the freeware utility Applejack. If you cannot start up in OS X, you may be able to start in single-user mode from which you can run Applejack to do a whole set of repair and maintenance routines from the command line. Note that AppleJack 1.5 is required for Leopard. AppleJack 1.6 is compatible with Snow Leopard. There is no confirmation that this version also works with Lion.
When you install any new system software or updates be sure to repair the hard drive and permissions beforehand. I also recommend booting into safe mode before doing system software updates.
Get an external Firewire drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
Carbon Copy Cloner
Data Backup
Deja Vu
SuperDuper!
SyncTwoFolders
Synk Pro
Synk Standard
Tri-Backup
Visit The XLab FAQs and read the FAQs on maintenance, optimization, virus protection, and backup and restore.
Additional suggestions will be found in Mac Maintenance Quick Assist.
Referenced software can be found at CNet Downloads or MacUpdate.
Be sure you have an adequate amount of RAM installed for the number of applications you run concurrently. Be sure you leave a minimum of 10% of the hard drive's capacity as free space.
Adding more RAM, if feasible, and a new, faster hard drive may also help pep it up a little.

Can't access online backup and sharing web site

Does anyone know how to access the Online Backup and Sharing web site from a computer that does not have the O/B/S software installed? I used to be able to go to My Verizon/My Services/Internet and hit "Launch" for O/B/S, and the link would go directly to the web site for uploading or downloading material. Now, that link takes me to a Verizon page that asks to activate the O/B/S service, and wants to download the software. My O/B/S service was activated years ago and has worked until recently without the software installed. There is no other obvious way to get to the O/B/S web site. (If it matters, I tried this in both IE 9, with Windows 7 64-bit, and Safari.)
After some effort, I got the help number for the outside vendor that runs the O/B/S service. They say that the Verizon web site should link directly to their O/B/S web site, regardless of whether or not the O/B/S software is installed locally, but that the failure to do so is entirely an error of Verizon's on the Verizon web site and they have nothing to do with it. They also said there is no way to bypass the Verizon web site to get to a Verizon O/B/S account on their web site. They said they have received many complaints about this from Verizon O/B/S customers, and that the same problem has even arisen when the O/B/S software is installed on the local computer.
So does anyone know if it is really necessary to install the O/B/S software on any computer used to access O/B/S, and if it is now impossible to access the material from any other computer? That would be a major reduction in the usefulness of the service that was not announced anywhere that I know of. I saw a strong of comments on this issue in the Forums from a few years ago, but the conclusion was that the problem had been fixed. It seems to have arisen again.

Anthony, I tried to private message you several times, but I kept getting an error message stating that my message had invalid HTML that was being removed, and to resend. It did not actually have any HTML, and hitting the resend button just led to the same message.
Also, since my last post, I downloaded the OBS software onto my computer. This gave me access to OBS from that computer. However, even after doing this, I cannot use the old method of directly getting to the OBS web site from My Verizon. The link from "Launch" does not work either on the computer with the OBS software or on any other computer. Rather, the link goes only to the Verizon page saying that my OBS service has not been activated (which it surely has been) and asking to download the OBS software.
If this is happening to everyone and not just to me, this means that material stored on OBS is only available from a computer that has the OBS software downloaded on it. That is certainly not supposed to be the case, and it would make OBS much less useful.
Again, the OBS technical people said that this was a problem that they knew about, but it was entirely a problem with the Verizon web site that they could not do anything about.
