ORA-00704: bootstrap process failure and SYSTEM datafile corrupt

We have an Oracle 10g Express database that is getting the following error on startup.
ORA-00704: bootstrap process failure
It is also showing that the SYSTEM datafile is corrupt. And unfortunately the backups are gone. Is there any way to recover from this without a backup? Maybe some hidden undocumented parameter???
We do have some full database exports from a couple weeks ago so it is not a complete loss but would really like a full recover.

Windows XP
We have tried allowresetlogs_corruption and allowread_only_corruption and no luck so far.

32bit Primary to 64bit Standby-"ORA-00704: bootstrap process failure"

Hello All,
As per the Doc ID 414043.1 it is possible to use mixed word size primary-standby configurations since 10g and better in 11g.
So i created my test env:-
OS: Linux 5.5 64bit
DB Name: TEST
Primary - TEST32 on 32bit Oracle Home
Standby- TEST64 on 64bit Oracle Home
I could apply TEST32's archive logs(manually) on TEST64 without any problem, but when i tried to migrate to 64bit it kept failed with "ORA-00704: bootstrap process failure ORA-39700: database must be opened with UPGRADE option"
What i did on TEST64 is:
1) Activate physical standby
2) Startup Upgrade
3)@?/rdbms/admin/utlirp.sql
4)@?/rdbms/admin/utlrp.sql
5)Shutdown
6)Startup
When i issue startup(step 6); it fails with

System datafile corruption

good morning all
What if in system datafile some blocks are corrupted in scenerio as below(db in noarchive mode but backup available-point in time recovery not important,data loss tolerated but want faster approach without shutting down db prefrably)
oracle 10g release 2
1)have cold backup /rman of few days old before corruption
2)can i use bmr of rman or export system from this server import on anoter server and export and import back on this server
3)or can i restore backup/rman of this db on other server,export system and import this on server where
system.dbf is corrupted
4)OR should i restore whole rman backup and replace whole db(point in time recovery not important here)
which approach is best
thanks

for the following points :
1)have cold backup /rman of few days old before corruptionyou have to remove the existing C/R/D files and restore those files from the last backup and start the database.
2)can i use bmr of rman or export system from this server import on anoter server and export and import back on this serverTaking export is possible but not sure whether there would be any problem while taking any export and also during the import as well.
3)or can i restore backup/rman of this db on other server,export system and import this on server where system.dbf is corrupted Its same as your second point but you are just doing it remotely
4)OR should i restore whole rman backup and replace whole db(point in time recovery not important here) which approach is bestThis point is right because the database is not in archivelog mode...
Cheers!

Intermittent lookup failures and system limits?

Hi,
on our deployment system we sometimes see intermitten failures of lookups. E.g. on the Webserver (Apache2.2) with a reverse proxy to an internal machine defined in /etc/hosts we will get "DNS Lookup failure", after a few reloads it works. Or restart of the apache helped, too. In our postgres mirroring script we have a similar problem. A host cannot be found even though the host is defined in /etc/hosts.
Since the problems are not 100% reproducable, I was thinking about some system limits (open files, processes?)
Did anybody run into a similar problem or has some hints where to look?
Christian

Hi,
I've been running a reverse proxied Webserver setup to an internal machine for over 4 months and not seen this problem. My reverse proxy instructions are located in /etc/apache2/sites/specifichostfile in the <IfModule modproxybalancer.c> module instructions.
I just use the internal IP to denote the machine not even bothering with a DNS entry. But an A record could be introduced to lookup the internal machine. If all the traffic on this domain goes to an internal machine you can specify the IP address in the WebService->General panel. In my case I am only diverting the /cgi-bin/ traffic in one case and Rails traffic in another, and so am more selective.
HTH,
Harry

Copy, count files, test path, process indicator and System.IO.FileInfo

I found this, sctipt, that I try to re-write.
As it is, it creates sub folders in the targetfolder, which I found out how to stop it from, by deleting the "\" backslash sign in line 9.
But what I also want is that subfolders if such should exist, also gets copied from $source to $target folder, as of now this doesn't happen. Reason why I chose to try to re-write the script is basically, I can read what it does and I like all the flashy
Things like counting and that it shows the percentage of the processbar AND the processbar :).
I just don't now how to re-write it proberly. By the way nothing should be re-named in the targetfolder every thing from sourcefolder should be "as is" in the sourcefolder.
$SourceFolder = "C:\Color1\TRID"
$targetFolder = “C:\Color2\TRID”
$numFiles = (Get-ChildItem -Path $SourceFolder -Filter *.*).Count
$i=0
clear-host;
Write-Host ‘This script will copy ‘ $numFiles ‘ files from ‘ $SourceFolder ‘ to ‘ $targetFolder
Read-host -prompt ‘Press enter to start copying the files’
Get-ChildItem -Path $SourceFolder -Filter *.* | %{
[System.IO.FileInfo]$destination = (Join-Path -Path $targetFolder -ChildPath $_.Name.replace(“_”,“\”))
if(!(Test-Path -Path $destination.Directory ))
New-item -Path $destination.Directory.FullName -ItemType Directory
[int]$percent = $i / $numFiles * 100
copy-item -Path $_.FullName -Destination $Destination.FullName
write-Progress -Activity “Copying … ($percent %)” -status $_ -PercentComplete $percent -verbose
$i++
Write-Host ‘Total number of files read from directory ‘$SourceFolder ‘ is ‘ $numFiles
Write-Host ‘Total number of files that was copied to ‘$targetFolder ‘ is ‘ $i
Read-host -prompt “Press enter to complete…”
clear-host;

@Jaap
Yes I want to overwrite existing files, since backup is taken care of by another script.
Now I encounter this error when trying to use your write-progress example:
Get-ChildItem : A parameter cannot be found that matches parameter name 'Files'.
At line:3 char:51
+ $Files = Get-ChildItem -LiteralPath $SourceFolder -Files
+

Here is the script as I thought it should look like:
$SourceFolder = "C:\Color1\TRID"
$targetFolder = “C:\Color2”
$Files = Get-ChildItem -LiteralPath $SourceFolder -Files
$NumberofFiles = $Files.Count
$Files | ForEach-Object -Begin {
$FilesCopied = 0
-progress{
Write-Progress -Activity "Copying Files..." -PercentComplete [int](($FilesCopied/$NumberofFiles)*100) -CurrentOperation "$FilesCopied files copied out of total of $NumberofFiles files" -Status "Please wait."

Installing update we had power failure and system will not boot

We do not have a current working back-up, how do I re-install the os w/o erasing the entire hard drive? We have a Intel Imac with snow leopard on it.

Thanks for the info. This is my fathers machine and I am the one that gets stuck fixing it when he has problems. I used to be an Apple Certified Repair Tech in 99/00 but that seems like a life time ago now.
The system came with 10.5. We upgraded to SL and have the disk and then to Lion which was a downloadable upgrade correct? I will take a look at the link you sent.
Thanks,
Matt

Offline Backup failed : ORA-00704, ORA-00604, ORA-01089 Errors

Hi Guys
I am facing issues with Offline backup in Production system.
I had Scheduled the offline backup for sunday evening, but monday morning i found prodution box, was down and i killed the netbackup Process.
checked Oracle was up.
Just started SAP and system start running fine.
Then found that backup (offline backup) was never started.
Found following errors in alert_<sid>.log and in *.trc files:
ORA-00704: bootstrap process failure
ORA-00604: error occurred at recursive SQL level 1
ORA-01089: immediate shutdown in progress - no operations are permitted

Can you guide me on this, as this has happened second time ?

Your database was trying to shut down, but in was hanging for some reason.
not much can be done, you are using Oracle 9207, try with 9208
you ware on an unsupported Windows 2000 version.

Process Failure when communicating over MODBUS using LabVIEW 2011 and DSC

I'm currently trying to read from a PLC's holding registers using MODBUS/TCP. I've confirmed that the PLC is updating the values and responding to MODBUS communication correctly using a third party program called Modbus Poll. However, when I try to poll the PLC using LabVIEW's shared variable engine, I am unable to read any values from the same addresses that I'm viewing with Modbus Poll.
My setup simply consists of a PC connected directly to the PLC over Ethernet, with no router in between. I am using LabVIEW 2011 SP1 with the DSC module.
I opened the NI Distributed Systems Manager to view the status of all shared variables in the Modbus library that I created and I've noticed that the CommFail bit is permanently set to "true". All other variables with a "read" access mode report "Process Failure". I've tried restarting the process as well as stopping and starting the local variable engine with no success. I've also restarted my computer several times to see if any services were failing, but this does not seem to have fixed the problem.
I finally resorted to monitoring communications over the network card that I have the PLC plugged into via Ethernet using Wireshark and I've found that while Modbus Poll is communicating with the PLC, many MODBUS and TCP packets are sent and received. However, when solely using LabVIEW or the NI DSM to communicate with the PLC, there does not appear to be any communication over the network card.
Something that may be worth noting is that I was able to communicate with the PLC and read values from it with the DSM on just one occasion, when I first figured out which addresses I should be reading from. It all stopped working shortly thereafter. Prior to this, "CommFail" was not usually set to "true" with my current configuration. Thinking that it was my firewall, I have since turned my firewall off, but this seems to have had no effect on the problem either.
Any help on this matter would be appreciated.
Solved!
Go to Solution.

Just a thought but I think the register addresses used by LabVIEW are one off of the actual register #. I was using a CRIO as a modbus IO Server and had to shift the register addresses by 1 to get things to work correctly (can;t recall if it was +1 or -1). This is documented somewhere on ni.com but can;t seem to find it now. But here is another link that may help:

System datafile block corruption - no backups and database in NOARCHIVELOG mode

Dear All,
Database version - oracle 11.1 Enterprise
OS - RHELinux 5.8
What are the options of recovering from physical block corruption when there are no backup available to perform block media recovery?
V$DATABASE_BLOCK_CORRUPTION reports two segments corrupted (please see attached image for details).
1 table in system datafile - sys_fba_barrierscn
1 index - (applicaiton index)
What are my options?
I know there is a possibility that the database will not restart after a shutdown due to corruption in system tablespace.
Database is in noarchivelog mode. So online backups are not possible and there aren't any full backups either.
I am thinking of below,
1. Run dbms_repair with fix_block_corruption. - Still database startup might fail?
2. Shutdown the database and take offline full backup with RMAN MAXCorrupt option.
Appreciate your suggestions and advises.
Thanks
Stefan

Thanks Sybrand,
Agree with your first two suggestions .
Also scheduled a expdp job tonight. (Only backup like thing they had was a expdp cron, but until today all the large tables were failing due to small undo_retention).
Yes. Flashback is not used. So hopefully it will not affect the a database restart i guess?
Related to dbms_repair, I was referring to - http://askdba.org/weblog/2010/08/physical-corruption-ora-1578-part-3/.
Where DBMS_REPAIR.FIX_CORRUPT_BLOCKS and DBMS_REPAIR.SKIP_CORRUPT_BLOCKS used.
Which i think will not use any redo.
Thanks
Stefan

Hi Janiv,
Below is a query that I believe should work for you. This query will do a sum when Type is 10 and an average when Type is 11:
            SELECT
            deh.name as NAME,
            deh.type as EventType,
            SUM(value) as EventCount,
            COUNT(*) as Occurrences
            FROM input as deh
            WHERE deh.type = 11
            GROUP BY deh.type, deh.name, TumblingWindow(minute,5)
            UNION
            SELECT
            deh.name as NAME,
            deh.type as EventType,
            AVG(value) as EventCount,
            COUNT(*) as Occurrences
            FROM input as deh
            WHERE deh.type = 10
            GROUP BY deh.type, deh.name, TumblingWindow(minute,5)
Concerning Device_Id, currently, we do ask that the fields be consistent and explicitly provided for each and every event. We cannot look at a previous event and get a field value from there.
I hope this answers your question,
Thanks
