Possible Corrupt Database?
I've been synching my Palm Treo 700p, iCal, and Entourage calendars on my MacBookPro, OS 10.4.8, and I think I may have a corrupt database. All the calendars have been set to delete events/meetings more than one year old, and none show any events earlier than one year ago, yet iSync keeps coming up and telling me I have hundreds of synch conflicts (most from 2004 and 2005). Can I delete the database without losing everything currently in my calendars? If so, which database do I delete?
Thanks,
Claude
You cannot delete anything without forcing a corresponding deletion of matching records elsewhere on all of your applications, devices and servers.
Given your brief description, it's likely that Entourage is the culprit. Isolate it from the remainder of your synchronization pool by temporarily disabling its connection to Sync Services, and see if the conflicts disappear. By reconfiguring sync clients, but not deleting sync records, you should be able to determine what is driving this conflict resolution process. Only by temporarily disabling or reconfiguring devices can you isolate the issue and resolve it.

Replay logfiles on corrupt database
I've got a machine here that has not been maintained very well. Someone with little knowledge of MaxDB has only kept Windows backups and no database backups. Also, there has been no LOG backups, everytime the log was full, someone just added another one :). Now one of the DATAvolumes is corrupt (it shows 0 kb) and the database won't come up. Everyone here is convinced that it won't come up ever again. Also, on top of all, the Windows backups aren't available anymore either. People feel sorry for it and just move on
So now I've got some spare time and I want to take a closer look at it. I've got a corrupt database, and I've got a lot of LOG volumes (not backups). I'm not a MaxDB guru either, so I've got the following questions:
Isn't it true that if you do not backup the database or the logfiles at all, all the database transactions committed after the installation still reside in the logfile(s)?
With this in mind, couldn't it be possible to install the system just as it was right after the installation, and after that replay the existing logfiles? I've created a copy of the system where I can fool around. I've found lots of ways to recover a database with logbackups, but not with the logfiles itself.
Isn't there anything I can do at all with the existing logfiles, with all the precious data in it? It has been a portal and there are (or were ) a lot of documents in it.
Who can help me out?>Only thing is that the general idea was to build it again (by installing the system again) and replay all the later on added information (by replaying the existing logfiles).
>I still find it strange that in fact all the data is there ( in the logfiles), but I cannot get to it.
>Or I'm misinterpreting the whole logfile mechanism.
Well - half and half I'd say.
It's true, all changes to the database are logged to the log area.
BUT (yes, a big BUT here), the critical point here is the starting point.
To have all changes correctly applied, the database must be sure that the database is really in the exact state like it was, when the log information starts.
This synchronization is done via the restart_record and the log_info_page.
In theory, if we would be able to generate a completely identical data area as it was, back then, when the history of log information began, then we would be able to recover the data.
Just creating a new database won't do, since the db_create itself is not covered by redologs and ends up with a different data area each time (e.g. for each database a DB-Identifier with the timestamp of its creation is generated and saved).
So, technically the only way I can think of would be to create a empty data area and than hack into the restart_record to fake the MaxDB into a recovery.
If you are a MaxDB kernel developer you might be able to do that...

Oracle 9i clob segment possible corruption
Hello all,
We are experiencing some select issues from a table containing a CLOB segment. Since I don't know too much about CLOBs and we are suspecting a possible corruption. What would be the next step besides a DBV on the datafile housing hat table?
I have read that there is a package called DBMS_LOB ... but not sure how to use
Much appreciatedCorruption? logical or physical?

Possible corrupt or injected data
Hello,
I have a question for the SQL Server security experts.
My scenario is as follows: I am currently migrating data off a legacy system, and into another. This system is notoriously hard to work with, and has been severely abused over the years. Many logical associations were broken, and band aided
back together. It is a sunset system, however demographic data still needs to be retrieved.
Upon loading the data into a slowly changing dimension in another system, I am running into an issue where the same values will not equal themselves. I have tried converting the data types, stripping all non-ascii characters from the string data.
I have checked the data lengths, all equal similarly length and stored string data. I am detecting no hidden characters within the string as well. There is no reason why this data won't equal itself. My only conclusion at this point is that
it is either corrupted or injected.
Are there any suggestions on how to detect possible corruption or injection? I have read many articles around sql injection, and I suspect that I am dealing with binary data injected onto the end of the string data. However, when I check the
byte size it looks normal.Physical corruption you would detect with DBCC CHECKDB
Corrupted foreign keys you could detect with DBCC CHECKCONSTRAINTS
If someone has maliciously manipulated the data in order to conduct any kind of second order attack via SQL Injection or otherwise, it really depends on the skillfulness of the attack how easily one could detect & comprehend that.
Hidden character may also have gotten into the system by badly written applications and imho are not necessarily an indication of an attack.
Maybe you could show us a sample.
If you truly suspect an attack going on though, you should follow your hopefully existing escalation procedures and get the system ready for a forensic investigation by making sure nothing can get changed any more. Unless you want to keep
that system running to try to catch the attacker “live”. But I do not recommend using a production system as a honeypot if you don’t know exactly what you are doing (and probably not even then).

B4.1 to V1.0 Migration with possible corrupt DB?
Hi,
I'm using B4.1 OK on Mac, but it takes over 3 minutes to load - splash screen with a spinning beach ball mostly, then unresponsive for a further couple of minutes until library shows up.
I also get an odd console message about the LR database, but all seems to work OK once loaded.
I'm wondering if it's going to be better to junk my existing library and start again with V1, rather than risk converting a potentially corrupted database.
I have always used the Write XMP Sidecars option, and imports from memory card have always been to DNG, so can I just start again by reimporting the whole photo store disk, and the DNG/XMP data will rebuild everything thats needed?
I'm not worried about collections/structure, but I do want to save the metadata etc.
Is there anything in the B4.1 database that I am going to need?
Cheers
d.Not really. Save out the XMPs or create DNGs and start from scratch. The time taken will be a one off hit.
v1 will try to convert the database format, and it also has an integrity checking routine. You might try this first.

--------Hi,
Your database is corrupted, hence there is no surprise you cannot retrieve successfully from it:
# db_verify -o cf_classes.db.duff
db_verify: Page 4: btree or recno page is of inappropriate type 0
db_verify: Page 4: totally zeroed page
db_verify: Page 4: Btree level incorrect: got 0, expected 1
db_verify: Page 3: unterminated leaf chain
db_verify: cf_classes.db.duff: DB_VERIFY_BAD: Database verification failed
Verification of cf_classes.db.duff failed.
Dumping the database with db_dump -da shows the following where page 4 should have been:
page 0: invalid: LSN [0][0]: level 0
prev: 0 next: 0 entries: 0 offset: 0
and a verification with a hex editor over the 4KB's of page 4, shows that this page is all 0s (zeros).
You need to run recovery over this database. For backup and recovery procedures review the followings:
- chapter 11 in the Berkeley DB Reference Guide, Berkeley DB Transactional Data Store Applications;
- in the Getting Started with Berkeley DB Transaction Processing, the sections on Backup Procedures and Recovery Procedures.
If your application is not using transactions (it is not set up as TDS, Transactional Data Store), you should review the section on Handling failure in Data Store and Concurrent Data Store applications.

Corrupted Database in Lightroom 3 Beta
Can anyone offer any help how to recover from a "corrupted
database" error on startup? It gives an option to repair, but it is unsuccessful. I was one who disregarded al the warnings about not using the beta for production, but I liked it so much that I just completed a huge wedding. Luckily, all my chosen files were exported as Jpegs but I have lost many, many hours of work. I also have LR2 which I had always used previously.Try your catalog back up file, just click to open the most recent and hopefully that will work and as long as you made regular back ups you should be OK. If all else fails import the files into a new catalog using the Beta and then update the files from the metadata (this will obviously only work if you save out the metadata. You can also do the same with LR 2 although if you used the new process version in LR 3 this will be lost.
Using a Beat for production work is not a good idea, but at least if you backed up catalogs and wrote data out as xmp side car or directly to file if you converted to DNG you can always recover. If you did none of these things and used a Beta then you really are in trouble! -
New mail messages not visible--"detected corrupt database" related?
I am using Mail.app and an iPod Touch with an Exchange server (Intermedia). All of a sudden in the last few days, recent mail on the server is not visible using Mail.app or the iPod Touch. I have deleted the mail accounts on both devices twice and done an entirely fresh download of all mail on both, and the problem persists.
Mail in the Inbox is visible. However, if I move an Inbox message to, say, Archive or Travel, then it becomes invisible--even though it is intact on the server and in its proper location there.
I have also repaired permissions and run sudo daily/weekly/monthly maintenance processes, to no avail.
In the console, I see the following error message. Could this be related and is there a way to fix it?

Hey friends, I'm in great trouble here.
I'm using Microsoft Visual FoxPro 9.0 on my Windows 7 machine. I had some DBF files which was created in MS Visual FoxPro. The files were undoubtedly valuable since they contained my crucial data related to my office work. The files are now invalid
therefore, inaccessible. I can't access any of my database files. Whenever I try to open one of them this comes in front of me: "File filename.dbf does not exist".
According to me this must be a file corruption error states the file is corrupted. I don't know how did it get corrupted. I'm dying to get these files back. Please help in this.
Thanks in advance.It is not necessary to rebuild a corrupt database. All corrupt databases can fixed in less than one minute.
The solution is: Open database to main screen
Copy the database but only one record(just pick a not recent record number at random; include "all", I usually name this database "FixMMDD" (( month Day))
Open original database to mainscreen and append the FIXMMDD.dbf.
You're done.
Occassionally you may have to update indexes. Very rarely are any records lost and when it happens those few records are clearly garbled.
I've been doing this for three years with no problems.
If you have fields that increment you'll have to adjust that for your last valid value.
OTHERWISE
I think those files of your which seem unreadable are corrupt. Just one thing always keep in your mind that corruption can make a file unreadable or useless. And due to this file becomes inaccessible. Any corrupt or damaged file can't be accessed
until it gets fully repaired. All you need just remove the error from your DBF files and after doing this you can access those corrupt files. The data inside those files will be readable right after you repair them. You just need to consider
about a software program or shall I suggest you about a tool which I have used?
Check this one: DBF Repair Kit
It will help you as it helped me. Just try its demo version
http://www.dbf.repair/ to see the preview of the content of the files which are unreadable.
