Recovery with missing archivelog

I've got a client whose 10gR2 database has been running with the SYSAUX tablespace marked for "recovery" for 9 months. To properly bring SYSAUX online, they need an archivelog from 9 months ago and it no longer exists.
They think they are in good shape, since they are in archivelog mode and are taking nightly RMAN backups.
I contend that they are walking on very thin ice: while they can restore from last night's backup, media recovery is impossible and they risk losing up to 24 hours of data.
Am I correct? Or is there some way to perform an RMAN "recover" operation that by-passes the SYSAUX tablespace, leaving it offline, but brings all the other datafiles up to date?
I have performed a test using a sample database and my theory is confirmed. But I would like a reality check in case I am missing something.
Thanks.

SYSAUX offline and inaccessible for 9 months, really? As you probably already know, there are a ton of objects that exist in this tablespace and therefore, you are probably not able to use some database features.
As far as recovery, you could use SKIP TABLESPACE to avoid recovery of this tablespace.

Recover database with missing archivelog...

Oracle10gR2 RHEL 4
Hi,
I am having a problem. I'm trying to recover my database to an previous point in time but the archive logs that I need were accidentally removed. Is there anyway I can restore it to a previous point in time? None of the SCN's are working no matter how far I go back (note: I can created the database lastweek so it can't go further than that).
Thanks

Manual Standby Database not in sync with missing archivelogs

Hello,
OS: Solaris
DB: Oracle 11.2.0.1 EE
Not Using ASM or RAC
I have a Production database that is in archivelog mode and a Standby DR server.
Both servers (Prod, Standby) have exact same structure and db name/version.
We manually scp archive logs and recover them to a manual standby database via SQL Scripts "cron". (I.E. set autorecovery on; recover standby database;)
We recently got out of sync with our log files and have not been applying them to the standby. As part of Prod Maintenance, these log files were deleted and are not available anymore.
I've tried several ways to "rebuild" our standby database. I have tried to Shutdown prod, backup all the db files and scp them to standby, re-create standby controlfile and startup mount and recover standby.
Every time I try to apply a new archive log via recover standby, these are the errors:
ORA-00279: change 211077622 generated at 1/27/2012 12:18:42 needed for thread 1

ORA-01152: file 1 was not restored from a sufficiently old backup
ORA-01110: data file 1: '/oradevices/PROD/oraPRODsystem1.dbf'
When I check v$log_history, the new logs have not been applied.
I've also tried the "Restore from incremental backup via SCN" method with same results.
Is there a way to re-create the standby clean and ensure that the log chain that is currently broken gets fixed or reset?
I would eventually like to get DataGuard in here, but that's not the case at the moment.
Thanks for your suggestions.
-Dav

if you are using the cold backup to create the standby database, Check that have you followed the following steps or not.
1. remove
all the datafiles and controlfiles from the standby database.
2. Create a new standby controlfile of the production for standby using the following cmd
'alter database create standby controlfile as 'Location';'
3. move the new controlfile to standby database server location as specified in initialization parameter file.
4. Restore all the datafiles to its appropriate loaction which was taken through cold backup.
5. startup nomount
6. alter database mount standby database;
7. recover standby database.
scp the archive log sequence that is asked by the database, from production.
You can try this steps.

Rman backup with a missing archivelog.

hello,
I backed my database up yesterday after you guys helped me fix few problems I had on it. I used RMAN with the following command in a run block:
*run {*
allocate channel t1 type disk;
backup current controlfile ;
backup database;
backup archivelog all delete input;
release channel c1;
At the end of the operation, RMAN indicates that and archivelog is missing and it couldn't find it. As a result, recover operation can be compromised. Now am confused because I do not know whether the command executed successfully or not and how to fix the missing archivelog.
Below is the entire output of the operation along with error message:

Here's my nderstanding and please correct me if am wrong:
The first 3 instructions of the run block executed successfully, but
the last one didn't. Is that so?
Whatever the understanding, do I have a backup? WHat can I do to have a consistent backup?
Thanks in advance.

Adomi,
It is sad to see you are still running RMAN in 8i fashion where you are on 10g.
The script is bs, sorry
run {
allocate channel t1 type disk; -- not required
backup current controlfile ; -- not required, as this is already done by backup database
backup database;
backup archivelog all delete input;
release channel c1; -- not required.
If you have controlfile autobackup on, you could just
backup database plus archivelog
and be done with it.
As you didn't make a RMAN backup from the start, your backup archivelog statement should have read
backup archivelog all skip inaccessible delete input;
Once that succeeds Oracle shouldn't need the archivelog anymore, and you should make a second backup without the skip inaccessible clause.

Report or GPO with missing Bit locker keys

Hello,
I have 2008 DC with schema upgraded to 2012 and win 8 clients.
I have configured GPO to store recovery keys to AD (no MBAM yet, i heard about it today for the first time)
but randomly it misses some users, it encrypt the drive but does not save the key and we dont come to know
until user is stuck for key.
If their a way to pull a weekly report to notify us about users with missing keys or GPO to force update the missing ones.
I also have SCCM 2012 SP roll up 4, if that can help.
Thanks in advance

This is not really what I am looking for, So I have enabled the Bitlocker classes and build the report.
It shows me 1 for computers with bitlocker enabled and 0 for not yet enabled.
But what I am really looking for a report to tell me about all the users whose drive is encrypted but key is missing in AD. or may be a report with all the recovery keys.
Any further suggestion please.

But you can contact to ORacle Support to help you to bypass the missed archived redo log file and apply archived redo log files generated after it. Do it only with the help of Oracle Support

Is there a way to create a report of topics with missing images?

If I move all images in a project to a different directory,
is there a way to print out which topics have missing images?
I would like to have all images in the HTMLHelp folder, since
this is the default folder that images are copied to when I insert
them from another source folder. If I move all images from my
"Images" folder to the HTMLHelp folder, is there a way to generate
a report that lists all topics with missing images?
Normally, I've been using the "Images" report to determine
which topics used that image before I moved them, but I'd like a
report that denotes which topics are missing images, period.
thanks in advance,
ChristyG

Hi ChristyG
As long as you only move the images within the RoboHelp
project, none should go missing!
Unfortunately, I don't believe you have an easy report at
your disposal that will advise which topics contain missing images.
Cheers... Rick

OSSNOTES for releasing process orders with missing parts in background

Hi All,
The bapi 'BAPI_PROCORD_RELEASE' is not releasing the process orders
with missing parts in background.
Is there any OSSNotes for releasing these process orders in backgound through this bapi.
Pls help.
Thanks .

Hi Suri - Thanks for your response. I tried both with blank(individual and collective) and 2 (collective req. only) but I still get the same result. I found one other setting that can solve this issue and that is checking the activate full confirmation logic at the the MRP group level in OPPR. I will test more and let you know if that works but we dont use MRP groups here at our client and that is why I was little hesistant to set up collective availability check parameters at the MRP group level. But looks like this is the only option that we can use to get this resolved.
Thanks,

Deleting rows with missing values in field in start routine of update rule

how can I delet rows with missing values in a specific field in the start routine of update rules?
I think ABAP code should look something like this:

IPhoto Book with Missing Pictures

I submitted this problem via the Apple support site but have not received an answer. I am hoping someone visiting this forum might have advice.
I ordered a 50-page hardcover 8.5x11 iPhoto Book (theme: Modern Lines) that I created using iPhoto 6.0 on a G5 Mac running OS 10.4.4. This was my first iPhoto book. The book, when assembled, looked perfect in the main book window, and I also saved a pdf of it, which was (and is) perfect as well. When the book arrived, I was very pleased with the quality of the printing, except that seven photos (some but not all of the photos on four separate pages) were not printed in their places in the book (there is just white space there).
I then opened the saved file of the book within iPhoto on my computer. When I went to the pages where the printed book is missing photos, I was surprised to see the following. In the main book window, the photos appear initially, for just an instant, and then disappear. In the main book window I then just see white spaces where the seven photos should be (just as in the printed book). This was not the case when I first created the book and placed the order – all photos were present in these places in the book (as the pdf I made just before placing the order confirms). Also, curiously, on the pages with the missing photos, even now the photos do appear in the small images of these pages in the page browser at the top of the iPhoto window, although as mentioned, the photos do not appear (except initially for an instant) in the main book window.
I have since updated to iPhoto 6.0.1 and OS 10.4.5, and the book appears the same with missing photos in the main window, but appearing correctly in the browser.
As you can imagine, I am very disappointed to have spent $70 for a book with seven of the critical photos missing. I assume that there is some bug in iPhoto causing this problem. Has anyone experienced anything like this before? Any suggestions?

G5 Mac OS X (10.4.5)

I looked on the forum for iPhoto 5, and found a discussion of a similar problem: http://discussions.apple.com/thread.jspa?threadID=315857&tstart=45
Essentially, the picture you see in iPhoto is a corrupted file. In my case, I deleted the pictures from the library that weren't showing up correctly, emptied the trash, and reimported the originals. Voila! No more missing images. Things are now showing up correctly.

How to deal with FLV with missing meta data?

I have and will get flvs in the future with missing meta
data.
I think for the most part the meta data that is missig is the
file length.
The exact files that are not working on our server are
working on some other companies FMS.
They must have some workaround actionscript on the server or
configuration that is making it work.
I'd like to know that workaround or that configuration
change. That would be the ideal fix.
I already know how to fix the FLV after I download it but I
wanted to know if there is another way to deal with this problem.
One were I can leave the FLVs alone.
Is there some serverside actionscript that would tell FMS the
length of the movie or change the configuration of fms to deal with
this somehow.
Any ideas?

If you are using the same database and referencing two tables then you dont need special configuration for it. You use single jdbc adapter. In ESR you create two statment structure one for each table. This is one option. The second option is use join statment and write query and in this case one statment data structure.
Please go through the help sap link for the jdbc document structure.
http://help.sap.com/SAPHELP_NW04s/helpdata/EN/2e/96fd3f2d14e869e10000000a155106/content.htm
The second option can be done using the below structure.
<StatementName>
<anyName action=u201D SQL_QUERYu201D >
<access>SQL-String with optional placeholder(s)</access>
<key>
<placeholder1>value1</placeholder1>

Error message after Recovery with discs

I have a Pavilion dv6911om. I had to replace the hard drive and then did a system recovery with the discs sent by HP but it failed to recover the computer. It gives me a CTOERROR.flg notepad with a bunch of information on it and from what I can tell it will not finish because my computer is offline but I have the wireless slider in the on position. HELP - what is my next step?

Try restarting the laptop and tapping away at the F11 key to see if the Recovery partition on the hdd was created and maybe capable of completing the install.
If no joy,scroll down on the page and get Partition Wizard Bootable CD ISO and ImgBurn to burn the iso image to cd and boot from it. Delete all partitions, create one and format. Next try booting from Recovery Disks again.

Recovery with RMAN in case of complete lost of all files

Hi,
I am using RMAN in nocatalog mode to backup my databases to tape using the RMAN-Module for Legato.
I4ve read that in case of loosing all my controlfiles i cannot easily restore the controlfiles.
Lets assume the following scenario:
I am performing a daily full backup with RMAN in nocatalog mode. Approx. 2 hours after the completed backup my machine crashes and all files (i.e. OS-Files, Database, Controlfiles) are lost.
Now I have to reinstall the OS, reinstall Oracle and restore the backup.
Due to backups made with RMAN in nocatalog mode i have the restore the controlfies prior to restore the database. Metalink says restoring the controlfile from RMAN in nocatalog mode is not that easy.
Is there any way to restore the controlfile from RMAN in nocatalog mode in case of complete crash ??
Thanks.
Ronny.

RESTORE CONTROLFILE FROM 'filename...' doesn't appear to be supported in 8i.
What are the options for 8i?.
I have the backup sets with me from my previous installation before crash which also contains Control files.
However I am unclear as to how to proceed wit RMAN recovery with those files. There seems to be no way to point RMAN to those backupsets since RMAN apparently reads its information from catalog or the control file in case of nocatalog.
I think if there is a way to atleast restore the control file from the backup set, RMAN can proceed since it will find all the other backup details there.
Any help is greatly appreciated.
thanks

COPA document with missing values

Hi Experts,
after posting in SD (debit memo rebilling) a CO-PA document is created, but with missing value for value field 'interest'. In transaction KE4I, there is correct assignment of SD condition to value field
'interest'. We use cost based CO-PA.
We have tried to Check Value Flow in Billing Document Transfer - transaction KEAT and also to Simulate billing document transfer with KE4ST, but in these transactions everything seems correct.
Can you please write any other reconcilliation reports I can try for this?
Which customizing do I have to check?
Are there any OSS notes for this problem?
Thank you very much for your help,
Michal

Hi,
The problem was solved using OSS note 20254.

To Dos not syncing with Missing Sync

When syncing with Missing Sync 6.0, my events sync fine. However, my tasks from my Tungsten E2 do not show up in the To Dos list on iCal. If I search in iCal, I can find them by name, but they do not show up in a list in the To Do pane. Any suggestions?

Same here. After the update to 10.5 I have succesfully done one sync between my Treo and iCal using MissingSync. Now iCal gives an error, see below. What is the workaround? Downgrading to 10.4.x? Or get an iCal 2 somewhere and run that?
I really want to get my ToDo and Calendar data from my Treo before I go from my Treo 650 to an iPhone. Any workaround is welcome.
