DB2 backup problem

hello,
I have a problem with the full online backup on a DB2 system
I get the fallowing error:
ERRORMESSAGE: Error -2048 in dmdb6bkp.c(1498):
SQL2048N An error occurred while accessing object "0". Reason code:
"6".
I cannot get any clue of the cause of the error from the log. I have also searched for SAP notes but did not find anything.
Can anyone help me in solving this issue?
Regards,
dalmi

Hello Dalmi,
as per the documentation on this error code:
http://publib.boulder.ibm.com/infocenter/db2luw/v9r5/index.jsp?topic=/com.ibm.db2.luw.messages.sql.doc/doc/msql02048n.html
SQL2048N
An error occurred while accessing object object. Reason code: reason-code.
Explanation
An error occurred while accessing an object during the processing of a database utility. The following is a list of reason codes:
6
The object being accessed is a table space and either the table space is in such a state that the operation is not allowed or one or more containers of the table space is not available. (LIST TABLESPACES will list the current table space state.) Examples of such states are: quiesced, offline.
What is the output of db2 list tablespaces show detail
State 0x0000 should mean they are all normal and should be accessible.
If not, check the output of db2 list applications show detail
check if an application si trying to perform a backup of a tablespace that migth have set them to an offline state.

paul

SQL2025N error in db2 backup to SAMBA filesystem

Hi,
thanks for the suggestion, but all permissions are ok.
The db2 user is in usbshare group:
drwxrwxr-x 1 root usbshare 0 2008-04-28 10:00 APPS.
We cannot use NFS, the disk is not in a system, it's an external disk connected directly to the network.
Regards and thanks for the replies.
Sonia.

Finally we fixed this problem.
The problem was the user owner in this filesystem, the owner must be db2<sid>.

Null values from DB2 cause problems

Hi,
I have another problem with database link to DB2 using IBM iSeries Access for Linux on 64 bit OEL5 with Oracle Database gateway and unixODBC 2.2.14.
DB link works. However, null values from DB2 cause problems. Date columns that are null on db2 return a date '30.11.0002', and character columns that are null return an error ORA-28528: Heterogeneous Services datatype conversion error.
isql returns correct results.
How can i fix this? Perhaps set some parameters for data conversion on the gateway?
Thank you.

If the driver is not fully ODBC level 3 compliant and misses functions, we're lost. But sometimes the drivers are ODBC level 3 compliant but miss the correct 64bit implementation. In those cases we can tell the gateway to use the 32bit ODBC level 3 standard by setting in the gateway init file:
HS_FDS_SQLLEN_INTERPRETATION=32

Db2 backup on aix

Hi,
We are running SAP on AIX 5.3 AND db2 udb 8.2.3. We have taken full offline backup from OS level. e.g. /usr, /sapmnt, /usr/sap/trans, /home, /db2/<SID>, /db2/log_dir etc. May i restore the backup on another server without installing DB2 software? and run the SAP? or do we need to re-install DB2 & SAP again and then restore the database backup?
Please guide.
-SN

Hi Jennifer,
it is much easier and less error prone to do a system copy with the build in DB2 backup and restore commands. Copying DB2 by copying files from one server to the other should only be done by experienced DB2 administrators and in most cases there is no need to do this. For example using the wrong OS tools may create sparse allocated DB2 container files and can create unexpected error situations.
The DB2 V8 software installer on AIX uses the OS installer. The DB2 V8 software is installed under /opt and the /db2/db2<sid>/sqllib directory contains links to this directory. Therefore it is not enough to copy the /usr/sap ; /sapmnt and /db2 directories. With DB2 V8 the software installtion directory is fixed. With DB2 V9+ the software can be installed in any directory and as a default new SAPINST versions install the DB2 software under /db2/db2<sid> .
To do a cold copy of DB2 you may also need to use the db2inidb and db2relocated tools ( mostly used for split mirror copies ), especially if you want to rename your dbsid. You can find more information about those tools in the DB2 docu. The SAP utility brdb6brt ( note 867914 ) may also provide some help.
Regards
Frank

DB2 Backup Verification

Dear Expert,
We tried backup verification using TSM script and get the result successfully. Now, we plan to perform backup verification using db2 command, our questions are:
1. Which command and option could be used that we can rely on?
2. Which the valid one to verify backup, using TSM or DB2 command?
Thanks in advance.
Kind Regards,
Rudi

Hi,
I tried using command db2adutl as follows:
- db2adutl verify full taken at 20090405103108 database <dbname>, showed the following:
Warning: There are no file spaces created by DB2 on the ADSM server
Warning: No DB2 backup images found in ADSM for any alias.
- db2adutl query full db <dbname> nodename <nodename>, showed the same as above:
Warning: There are no file spaces created by DB2 on the ADSM server
Warning: No DB2 backup images found in ADSM for any alias.
Please advice.
Thanks and Regards,
Rudi

DB2 Backup & Restore Method

Hi Gurus,
I have a source system which is ECC6 running on Windows Server 2008 & DB2 9.7 FP2 database. I want to build or copy the exact system to diffrent office. I have done a fulloffline backup on the server. The target system will be suselinux and same database which is DB9.7FP2.
So i have install a ECC6 system on the target system with same System ID,Hostname as the sourse system. . I am not sure what to do next. Please guide me how to restore the database using the full offline backup that i done on the sourse system.
Basically i am just doing a system copy but using the backup restore method.

Hi,
Assuming you're performing system copy by using db2 backup/restore method.
If you would like to take a complete set of (online) backup image which you can restore, rollforward and bring the db into consistent state, you can use "INCLUDE LOGS" option of db2 backup command.
The backup image would include the range of log files required to restore and roll forward this image to some consistent point in time with this option.
On the other hand, you can specify a path to be searched for required logs during recovery. There's an option "OVERFLOW LOG PATH" for rollforward command.
For this issue u will get more information for below link

Actually it should execute the dbmcli command as

But I donu2019t know where to make changes so that when I start the backup through DP GUI it should use backup tool as u201CBACKu201D
But same DP backup specification is working through MaxDB Database Manager GUI.
Any solution appreciatedu2026
Thanks,
Subba

Hi Natalia,
Thanks for the reply...Please find the answer as below,
-> What is the version of Data Protector?
Data Protector 5.5
-> What is the version of the database?
SAP MaxDB 7.6
-> According your information you could use the DBMGUI to create the medium of u201CBACKu201D type and create the databackup using this medium. Correct?
Yes
The problems are with Data Protector GUI, not with MAXDB or DBMGUI. Correct?
Yes
Please let me know where to make any changes or any enviornment settings to be done in Data Protector GUI so that it will use the medium "BACK" as backup tool while i start the backup through Data Protector GUI.
Thanks,
Subba

Backup problem with LMS 3.0 on Solaris

Hi All,
I'm encountering problems with LMS 3.0 when I try to do a backup. After you hit OK on the window that says "Do you want to backup now?", an error would pop up saying: "Enter a new directory name or ask the system administrator of the Ciscoworks Common Services server to make the directory accessible to user casuser", thus I cannot proceed with the backup process. When I do backup, my login privilege is admin. Even tried to do backup on the same partition as my CSCOpx directory but to no avail.
Appreciate your help on this guys. Our LMS 3.0 runs on Solaris platform. Thanks in advance.

Hi Joe,
Thanks for your prompt response. By the way, what is a casuser? Is he also one of the user that can be found on the Local User Setup on Common Services? The scenario here is that, I am not the one who installed the Ciscoworks LMS 3.0 on the client side, so I am not aware on how they did the installation procedure for the application. I remember assigning casuser password during installation on our other clients that has LMS 3.0.
Will the write access on the backup directory for the casuser be done by the Solaris root administrator?
Thanks for your help.

Encrypted backups problem

I have a problem that I can't make any sense of...
Reproduced on 2 PC's and 2 different iPhones. PC's are windows 7 and have never had itunes installed. Phones (3GS) have never been sync'd with itunes anywhere. Setting that up now so that I can take a backup to migrate to new 4S phones. I install itunes and authorize the PC for my apple store account (AppleID), then connect the phone. The "encrypt backups" option is checked by default. If I try to uncheck it it asks for a password - I have never set one, this is a fresh install. No backups have ever been done. I can right click the device and choose "backup", and it does take a backup. When I try to restore it to the 4S it asks for the password. I have never set one. I uninstalled and reinstalled itunes, and repeated the exercise on another PC. Same deal. "encrypt" is checked by default and needs a password to turn it off, but I have never set one.
I have tried the lock code for the phone, the apple id password, the passwords of every email service on the phone, and the windows password. None work. I have tried about 500 other random words but nothing works. If I go into iTunes preferences/devices it does not show any existing backups as being present.
So, I cant turn off encryption, and I cant restore any backups that I take.
Anyone got any suggestions? It makes no sense to me at all.
Thanks

iTunes and encrypted backups
In the iTunes Summary screen, select "Encrypt iPhone backup" if you want to encrypt the information stored on your computer when iTunes makes a backup. Encrypted backups are indicated by a padlock icon, and a password is required to restore the information to iPhone. You may want to write down the password for your backup and store it in a safe place. If you use a Mac, when you set a password you can select to store the password in the keychain. With iOS 4 and later, you can transfer the iOS keychain backup to a new device if you encrypt the backup.
Warning: If you encrypt an iPhone backup in iTunes and then forget your password, you will not be able to restore from backup and your data will be unrecoverable. If you forget the password, you can continue to back up and use the device, however you will not be able to restore the encrypted backup to any device without the password. You do not need to enter the password for your backup each time you back up or sync.
If you cannot remember the password and want to start again, you must perform a full software restore and when iTunes prompts you to select the backup from which to restore, choose set up as a new device.

Backup problems with external hard drive

I bought a WD passport external hard drive and copied my itunes library onto a file there. I re-set the location of the library on itunes to the drive on the external hard drive. So far I have not deleted anything from my computer hard drive. However, when I am in itunes and click onto a song, nothing comes out of my speakers. Everything looks normal, as if the track is playing, but nothing is happening. I tried buying a new track off of itunes online, downloaded it, and installed it on my ipod; it plays fine, on my ipod, but will not play on the computer. Something is obviously wrong, but I can't figure out what has happened. Any help out there?
Thanks!

It sounds to me like your iMac is on it's last legs....at least the internal hard drive. If you can't make a new Time Machine backup I would advise you replace your iMac as soon as possible.
Assuming your three-week old backup is sound you should have no problems moving everything over to a new Mac. I would recommend you use the Setup Assistant that appears when you start up the new Mac (and note: It only appears the first time you start the new Mac; you can move everything over later on via Migration Assistant, but you may see issues with accounts if you opt for that route).
I don't think you need the Genius Desk for Setup Assistant. You only have to power up the new iMac, answer a few questions....select "....From Another Disk..." When it asks how you want to move everything over....connect up your Iomega external drive...and wait for it to finish. (Could take several hours depending on the amount of data you're moving).
A couple of notes:
1. If your Iomega is a Firewire drive you'll need a Firewire to Thunderbolt adapter to connect it to your new iMac.
2. If you need to load CDs or DVDs remember the new iMacs don't contain an optical drive. You would need to get an Apple SuperDrive or third part external burner if you need that functionality.
I'm puzzled by the comment made in Seventy One's post questioning the reliability of the new iMacs. I upgraded from a 24" early 2008 model to a 27" model and everything works flawlessly. I hardly ever see the beachball anymore.

HT201210 update Ipad 2 to IOS 5.1.1 backup problems

When I try to update my Ipad 2 to IOS 5.1.1 a message says the backup could not be saved. Try again. How can I solve this problem? Thank you....I work with MAC and Windows 7...

There is no problem. That is how this process works. You should backup the iPad, and transfer purchases before you update the iOS.
Read this before updating your iPad.
How to update your iPhone, iPad or iPod Touch
And - If she bought the music with her Apple ID - the music does not belong to you. She may have bought the songs for you, but that is not how iTunes "sees" it. The purchases are tied to her ID - not to yours.

ITouch cannot be updated because it was disconnected, also some extraordinarily long backup problems.

I have a 4th gen ipod touch and i've been having this problem for a while. I'm on 4.3.3 and I don't jailbreak, I buy all my apps etc, but whenever I sync, it won't properly do it. It will start the sync by backing up. Now, I don't actually have a single back up meaning this is technically my 'first' backup. I know that 'first' backups are supposed to take longer, but it either a) takes over 3 hours (i've left it on for this long then gave up) or b) will go through and just before completing, say that the ipod was disconnected and thus was unable to backup. Occasionally, it will go through with the backup when i right click on my iPod in iTunes and select 'back up' but when I go to check everything, including my preferences > devices > backups, nothing has changed. I don't have a single backup on that list, its white and bare.
I don't have a single backup because although I managed to get this iPod fine, new from the apple store and backup for the first time then, after a while it stopped properly syncing, aka this problem. I was then recommended by some random site that I can't recall to delete backups and backup for the 'first' time again. I've also tried clearing some apps to see if that was the problem, as well as emptying some of my photos, but although i've not cleared all the apps nor all the photos, it doesn't seem to make a difference.
When I try to update to 4.3.5, it will extract information, proceed to Back up (step 1 of 5) and somewhere in the backing up process my iPod Touch will reboot and the apple logo plus a loading logo (the white lines arranged in a circular motion, when things are 'loading') ontop will appear. From then on, regularily will my iPod Touch beep with a high pitched noise that I can't put my finger on, but is familiar, until the backup ultimately fails with the message "iTunes could not back up the iPod because it was disconnected."
I've tried different USB ports, I do NOT use a hub. It also does not sync songs as when I try to put more songs on my iPod, it requires to back up. I've also tried clicking the (x) to stop the backup but clicking it doesn't even do anything.
I've wanted to try to restore, but apparently I can't even do that because it TOO requires to back up right after restoration, it will fail the backup and revert my iPod to what it was before.
Please tell me that this is a problem I can fix easily, it's a fairly new iPod Touch.
