Create database fails with error ORA-01505: error in adding log files

hi all,
hope someone can help me out, I'm trying to create a database using a SQL script, the content of the script is:
create database testora
user sys identified by oracle
user system identified by oracle

It fails in creating the database with the following output:

create database testora
ERROR at line 1:

ORA-01505: error in adding log files
ORA-01184: logfile group 1 already exists
Process ID: 3486
Session ID: 1 Serial number: 3

sorry to revive this thread but i have one more issue with this. I created a database with DBCA insetead of CREATE DATABASE command and selected option for Fast Recovery Area space. This automatically set initialization parameter db_recovery_file_dest and db_recovery_file_dest_size, but did not create a OMF redo log group, but instead created three redo log groups with 1 member each.
select * from v$logfile returns:
1          ONLINE     /u01/app/oracle/oradata/testdb2/redo01.log     NO
2          ONLINE     /u01/app/oracle/oradata/testdb2/redo02.log     NO
3          ONLINE     /u01/app/oracle/oradata/testdb2/redo03.log     NO
Any idea why if creating a database with create database command and specifying db_recovery_file_dest creates an OMF redo log group and with DBCA it doesn't?

ORA-00054 error when loading Oracle table using Data Services

Hello,
we are facing ORA-00054 error when loading Oracle table using BO Data services
(Oracle 10g database, BODS Xi 3.2 SP3)
Test Job performs
1- truncate table
2- load table (tested in standard and bulk load modes)
Scenario when issue happens is:
1- Run loading Job
2- Job end in error for any Oracle data base error
3- When re-running the same Job, Job fails with following error
ORA-00054: resource busy and acquire with NOWAIT specified
It seems after first failure, Oracle session for loading the table stays active and locks the table.
To be able to rerun the Job, we are forced need to kill Oracle session manually to be able to run the Job again.
Expected behaviour would be : on error rollback modifications made on table and BODS stops Oracle session in a clean way.
Can somebody tell me / or point me to any BODS best practice about Oracle error handling to prevent such case?
Thanks in advance
Paul-Marie

the ora-0054 can occure depending how the job failed before. If this occures you will need the DBA to release the lock on the table in question
Or
AL_Engine.exe on The server it creates the Lock. Need to Kill Them. Or stop it..
This Problem Occurs when we select The Bulkloading Option in orclae We also faced the same issue,Our admin has Killed the session. Then everything alright.

JBO-26030 and ORA-00054 error when updating a certain row

I have a page that saves data when you leave a cell in a table. Everything seems to work fine, but when you get to some cells the JBO-26030 error pops up and then no matter what you do you can't ever save anything on that cell. You can close everything down and reopen and change other cells, but when you go back to that cell the error message always pops up. I think it's mainly happening on the cell that is a drop down with 3 values (P, F, and NT). P is the value and key for the drop down.
Then when I go into the database through Toad I try to change the value just so see what happens and that's when I get the ORA-00054: resource busy and acquire with NOWAIT specified error. This again only happens when editing that row.
Any help is appreciated...Thanks!

This error is caused when the block property 'DML returning values' equals YES. This property was introduced as of forms 6. What does it do ? As per the on-line help of Forms, "A database update or insert action may initiate server-side triggers that cause alterations or additional changes in the data. In Release 6, when using an Oracle8 database server, Forms uses the DML Returning clause to immediately bring back any such changes. When this property is set to Yes, Forms will automatically update the client-side version of the data, and the user will not need to re-query the database to obtain the changed values". When this property is switched to yes the generated insert/update statement will contain the 'returning clause' and this clause is causing the error.
As far as I have tested, the only way at present, to get rid of this error is to set 'DML returing values' to NO. So, not to use this functionality.

Nigel,
While the error messages you are seeing might not be anything to worry about (you will see some of these even in the best of circumstances, but I cannot speak to yours, specifically), you shouldn't be seeing any "wonky" behavior. The fact that you are indicates that something might, indeed, be wrong.
My best advice to you would be to start with a clean slate. I just received a new machine, myself (this beautiful new 17" Powerbook), and I spent the past day doing just that: starting "clean."
What I mean by this is formatting the drive right out of the box, then reinstalling. And, not just any format, but a "zeroing" of the entire drive. This took about 45 minutes on my PB, but the process will "map out"any potential bad blocks on the drive, thereby reducing the possibility of encountering disk errors for the near future. Another good reason to reinstall yourself, even if you don't "zero" the drive, is that Apple often ends up installing the wrong version of an OS to a given machine, especially if that machine has just been released. We see many cases where a user will find, by reinstalling from the disks that come with new Mac models, that the OS is slightly different than the one that was originally installed, and that the disk-installed version works without problems. Hmmm.
Unless and until you do this yourself, you will not have a firm foundation from which to troubleshoot any problems you might be having. If, after having done this, you find that you still have problems, the next thing to look for is a bad RAM module. If you rule out a bad RAM module, only then should you consider the possibility that something is wrong with the machine, itself.

Errors in system log?

OK, so I'm relatively new to Mac OS X, but that's on the back of some 20 years of working with UNIX, so I'm well placed to handle Mac OS X.... or so I thought!
In fact, compared to generic UNIX systems, there's so much added to Mac OS X that it might as well be a totally different system.
Anyway, I've got this iMac G5 (iSight) 2.1 GHz, which came with 10.4.2 installed, and which I've fully updated (using Software Update) to 10.4.3. After the update, a few glitches have revealed themselves - like the Dock will sometimes just apparently lock up - clicking back on the desktop seems to be a fairly reliable way of unfeezing the Dock, but it's annoying nonetheless.
The glitches prompted me to look further into the system, and in particular, when I look at the system log, via Console, right after rebooting, I see some messages there that may or may not be of significance:
- SystemStarter[879]: authentication service (887) did not complete successfully
- localhost kernel[0]: AppleU3: WARNING: platform-chip-fault expected, but not found
- launchd: Server 0 in bootstrap 1103 uid 0: "/usr/sbin/lookupd"[65]: exited abnormally: Hangup
I must admit, the second of those seems a bit odd to me!
But, can anyone tell me how 'bad' these errors are? Do I need to delve further into their causes, or do Aqua and Darwin handle such 'events' quite gracefully (which I'll accept is more than possible)?
Whilst I was talking with one of the AppleCare guys earlier today, I tried to ask him about these syslog messages, but the response I got was that I should consult http://www.apple.com/support/mac101 !!! Right, very helpful!
AppleCare is great, I think, for users who simply need a bit of hand-holding and instruction in how to use their Mac. That's fine, as long as everything is working as it should - but when we're more advanced as users than that, and we have a more technical issue to resolve, whereand how are we supposed to get help from even more knowledgable support personnel?
Or are these discussion forums the best bet?

Errors in system.log since leopard upgrade

I have a mac mini core duo 1.83, with 2gb ram.
It was running Tiger until I upgraded it to Leopard about October 27th.
I used the archive and install installation method.
It has been running fine. The only "glitch" I have noticed is a very occasional
pause in music playing in iTunes.
While investigating the cause of that, I realised that the system.log file is very large, and there are many many instances of this error in it.
Dec 10 15:42:11 macmini Unknown[36394]: Error loading /System/Library/Extensions/IOUSBFamily.kext/Contents/PlugIns/IOUSBLib.bundle/Co ntents/MacOS/IOUSBLib: dlopen(/System/Library/Extensions/IOUSBFamily.kext/Contents/PlugIns/IOUSBLib.bu ndle/Contents/MacOS/IOUSBLib, 262): no suitable image found.

Am I likely to see any problems other than the large log files?

Large log files are potential problems. The larger they get the greater the probability they will become corrupted. You should use some software to clear out the logs regularly by running the built-in Unix scripts. See my maintenance FAQ for helpful suggestions:
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 4.0 is now Intel Mac compatible. TechTool Pro provides additional repair options including file repair and recovery, system diagnostics, and disk defragmentation. TechTool Pro 4.5.2 is Intel Mac compatible; Drive Genius is similar to TechTool Pro in terms of the various repair services provided. The current version, 1.5.1, is 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.
OS X automatically defrags 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.
I would also recommend downloading the shareware utility TinkerTool System that you can use for periodic maintenance such as removing old logfiles 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 commandline.
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):
1. Retrospect Desktop (Commercial - not yet universal binary)
2. Synchronize! Pro X (Commercial)
3. Synk (Backup, Standard, or Pro)
4. Deja Vu (Shareware)
5. PsynchX 2.1.1 and RsyncX 2.1 (Freeware)
6. Carbon Copy Cloner (Freeware - 3.0 is a Universal Binary)
7. SuperDuper! (Commercial)
The following utilities can also be used for backup, but cannot create bootable clones:
1. Backup (requires a .Mac account with Apple both to get the software and to use it.)
2. Toast
3. Impression
4. arRSync
Apple's Backup is a full backup tool capable of also backing up across multiple media such as CD/DVD. However, it cannot create bootable backups. It is primarily an "archiving" utility as are the other two.
Impression and Toast are disk image based backups, only. Particularly useful if you need to backup to CD/DVD across multiple media.
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 www.versiontracker.com and www.macupdate.com.
I'm only supposing, here, but I think your log errors are generated by left over elements of Tiger not removed when you installed Leopard. This is always a potential problem with upgrade installs and Archive and Install when moving to a new major OS version. I generally recommend doing an Erase and Install.

Netinfod errors in system.log

These errors appear in my system.log every 30 minutes:

Either you're not giving the full picture here, or you missed:
(issued from the session that has an outstanding transaction on your table) So:
-Are you capable of indentifying sessions that lock 'your' table? (Any tool available?)
-Do you have a DBA around you can ask?
-Database version?
-acces to datadictionary views like V$LOCK amnd V$LOCKED_OBJECT
-is this a development or a production problem? (I think it's a development problem)
any other suggestions???Give the full picture here, instead of letting us 'fire guesses at you'.
That's like walking down 'Cumbersome Avenue'.

Mac Pro freezes frequently after "NVChannel" error in system.log

Hi,
Can anybody here with a 2008 Mac Pro run the Folding @ Home client without hard crashing the Mac?
I have a 2008-model Mac Pro, with the nVidia GeForce 8800 GT, which freezes frequently. As detailed in an earlier post[1], the graphics driver sees to be implicated, as just before the freezes, messages like this appear in the system log:
kernel kern 3/30/08 7:53:52 PM Debug NVChannel(GL): Graphics channel exception! status = 0xffff info32 = 0x6 = Fifo: Parse Error
kernel kern 3/30/08 7:53:52 PM Debug 0000000b
If you google for "NVChannel freeze" then you will find many many Mac owners whose machines freeze with similar symptoms. Apple recently released the "Leopard Graphics Update" which fixes such problems for some users, but not others.
In my 2008 Mac Pro's case, I have found a way to trigger the freeze 100% of the time: install the freeware Folding@Home client[2], and run the demo in the Applications folder. Just opening this app causes those messages to appear in the log, and then the Mac freezes.
I work for a software company which writes Mac software, so now that I have found a reliable way to reproduce this issue, I will be filing a bug report through Apple's bug system. But for my own sanity, I would like to collect more info, if possible.
If you have a 2008 Mac Pro and want to be cool, try running the Folding @ Home client app (link below) and post in this thread:
a.) whether or not your Mac froze
b.) what video card you have
c.) how much RAM you have
Thanks!

Yup… this is a memory fault and you should firstly try reseating the RAM and memory Risers (even change the slots they are in - depending on your configuration of course). The can often remove these issues.
Failing that, I would contact the RAM vendor and discuss it with them. Depending on how they sell things it might be simpler to send a kit, as in two DIMMs, back for replacement rather than a single DIMM that is part of a kit. Also, unless they specifically match your original DIMMs then you'd be better of returning both.
