Log Shipping Gap In Log Chain

May 7, 2007

Log Shipping on SQL 2005 is failing because of a gap in the log chain. The schedule is every 15 minutes, the backup and copy jobs run without issue. The failure occurs early in the morning when there are no users, maintenance activities, or scheduled jobs - this has happened twice since we applied SP2. The database that is participating in the log shipping is approximately 20Gb, and recovery takes several hours.

Are there any known issues with log shipping on SP2? Any ideas why this might be happening? Is there any other information I can provide to help debug this issue?

Updategrams And Chain Relationships...

Jul 2, 2003

Hi!

Is it possible to use updategrams on chain relationships? When I try
I always get this message:

<?MSSQLError HResult="0x80004005" Source="Microsoft XML Extensions to
SQL Server" Description="There is an inconsistency in the schema
provided"?>

If you have got updategrams to work with chain relationships, please
let me know. Thanks for any help!

Server: Msg 8908, Level 22, State 6,

Chain Link Mismatch

Sep 19, 2005

I have been throwing these lovely errors on my db (approx 16Gb) all of a sudden - they might all be related:

1) Operations Manager Critical Error Alert
Severity: Critical Error
Status: New
Source: MSSQLSERVER
Name: Attempt to fetch logical page belongs to different object .
Description: Error: 605, Severity: 21, State: 1
Attempt to fetch logical page (4:1878339) in database 'NGProd' belongs to object 'claim_requests', not to object 'Assessment_'.

2) Event Description:
Error: 644, Severity: 21, State: 5
Could not find the index entry for RID '36303030318eefd3713d52f4a85df3b0b8a889904e4e608102703230303530393139'
in index page (3:271543), index ID 9, database 'NGProd'.

3) Event Description:
Error: 8908, Severity: 22, State: 6
Table error: Database ID 10, object ID 86095893, index ID 0. Chain linkage mismatch. (4:1880687)->next = (4:441596), but (4:441596)->prev = (4:441595)

dbcc checkdb gives me 0 errors & running the built-in integrity reports does not seem to find anything.

I have been told that my db has "cracks" in it, and that I need to export ALL of it and then re-import. Seems a bit too much work...

Anyone have any ideas on what I should first attempt to do? I don't even know how to fix these errors... seems that I only throw then when users are accessing specific records.

Any help would be most welcome!

Thanks,

How To Find The Head Of A Blocking Chain?

May 1, 2002

I'm trying to write a script that will go against sysprocesses (I think) and find the head of a blocking chain, and how many SPIDs it is blocking on down the line.

I found a reference to a script called head_blockers.sql in the Swynk Scripts database (posted March 2000), but the script appears to no longer be available for download.

Any help would be appreciated!

Thank you,
Susan Jones

Chain Linkage Mismatch Errors

May 4, 2004

Recently I have been getting a barrage of errors such as:

DESCRIPTION:Error: 8908, Severity: 22, State: 6
Table error: Database ID 16, object ID 1893581784, index ID 2. Chain
linkage mismatch. (1:17214)->next = (1:17060), but (1:17060)->prev =
(3:178).

and

DESCRIPTION:Error: 605, Severity: 21, State: 1
Attempt to fetch logical page (1:164756) in database 'Clients' belongs
to object 'activities', not to object 'entity_address_check'.

The problem began to originally manifest itself with a couple errors
similar to:

DESCRIPTION:Error: 605, Severity: 21, State: 1
Attempt to fetch logical page (1:4930) in database 'tempdb' belongs to
object '1732152167', not to object
'#allrowstable____________________________________ __________________________________________________ _________________000100003472'.

So far all of the errors have been isolated to indexes and I have been
able to repair the problems with CHECKDB fast_rebuild or by dropping
the index that is causing the error and recreating it. At times the
errors will appear for a couple hours overnight and then resolve
themselves before the morning. Originally the problem began to appear
on a single SQL Servers and now appears daily on all three SQL
Servers.

We've investigated whether the NOLOCK optimizer was the culprit but
out of all of our views and procedures there was nothing compiled with
that optimizer in any of the databases, so this seems an unlikely
cause (SEE http://support.microsoft.com/default.aspx?scid=kb%3Ben-us%3B308886
)

We've reviewed IO on the servers, and nothing appears out of the
ordinary. We have even checked into the possibility of unreport IO
errors (SEE http://support.microsoft.com/default.aspx?scid=kb;en-us;826433&Product=sql2k
) but this still is inconclusive. HP did admit that their disc array
is not fully compatible with W2K Adv Server SP3, but the problem only
recently appeared and the upgrade to SP3 was completed nearly 2 months
ago.

We are running SQL Server 2000 EE, SP3 build 2195 on Windows 2000
Advanced Server. The server is setup as an A/P cluster on 2 HP
Proliant servers with a HP HTA200 disc array.

If anyone has any insight or suggestions, it would be great to hear
them.

DBCC - Chain Linkage Problem

Aug 31, 2005

I'm having a problem where I see consistency errors in my databases on a regular basis (at least twice a week).

I have several databases running on the same instance of SQL Server. During any given week, at least one of the databases will show consistency errors. At times, more than one at the same time will show these errors. These have odd effects on queries, sometimes making a SELECT (for instance) that should run in 5 seconds have to be killed after running for over an hour.

I'm running SQL Server 2000, version 8.00.194. The host OS is Windows 2000 with the latest service pack. RAID 5 is the storage solution.

Below are two DBCC outputs from different databases on the same machine. They are slightly different in that one starts out with "Parent node for page was not encountered"; and the other with "Page is missing a reference from previous page".

My hardware guys assure me there is no hardware failure going. I don't see anything that would suggest there is one in any of the event logs or in the Dell OpenManage system checks.

These DBCC errors are repairable without data loss, yet the databases have to be taken down to single user mode to do so (unacceptable during the day). But at the same time, certain operations in the database become impossible to perform when these errors crop up (such as the aforementioned infinite SELECT problem).

Any help in diagnosing why these pop up, or how to prevent them would be greatly appreciated.

The DBCC outputs:

SQL Server Express Certificate Chain Problem

May 28, 2007

Hi All,

I was trying to install Sql Server Express 2005 using the setup made using Visual Studio 2005 Publisher Wizard, as a pre-requisite. During this i'm getting the following error...

"SQL Server Setup could not connect to the database service for server configuration. The error was: [Microsoft][SQL Native Client]SSL Provider: The certificate chain was issued by an authority that is not trusted."

What does this mean? Anyone is familiar with this, then pray please post a reply. I'm in the middle of nowhere now....

Thanks in Advance....

Log Shipping - Switching Recovery Model In Log Shipping

May 13, 2007

Hi

I could not able to find Forums in regards to 'Log Shipping' thats why posting this question in here. Appriciate if someone can provide me answers depends on their experience.

Can we switch database recovery model when log shipping is turned on ?

We want to switch from Full Recovery to Bulk Logged Recovery to make sure Bulk Insert operations during the after hours load process will have some performance gain.

Is there any possibility of loosing data ?

Thanks

SQL 2012 :: Breaking Backup Chain Or Sequence In Server?

Aug 4, 2014

We are running SQL Server 2012 on Windows Server 2008. Just wondering what type of actions would break the backup-chain or backup sequence? For instance, if you have tlog backups being taken every 10 minutes and you stop the SQL Server Service for say 30 minutes. Would this action break the backup chain? Or would everything return to normal once the SQL Server Service is restarted?

Access Denied Error When Calling Several SSIS Packages In A Chain

Jun 22, 2007

Hi.

I have problem executing several SSIS-packages in a chain.

To be more precise:
I have implemented a Biztalk 2006 application which via a local webservice executes an SSIS package. The package it self calls another SSIS package, which is located in the same folder as the calling package. The second package then calls a third package etc.

The problem arises, when the first package calls the second package. An Access Denied exception is received. Can any one explain me how to fix this?

The user connected to the application-pool that the weservice is running under, has execution-rights on all of the packages.

Thanks

Log Shipping: How To Failback After A Failover Log Shipping?

Jun 8, 2006

Hi,

I 'm sure I am missing something obvious, hopefully someone could point it out. After a failover log shipping, I want to fail back to my inital Primary server database; however, my database is marked as loading. How can I mark it as normal?

I did the failover as follow:

I did a failover log shipping from the 2 server Sv1 (Primary) and Sv2 (Secondary) by doing the following

1) Stop the primary database by using sp_change_primary_role (Sv1)

2) Change the 2nd server to primary server by running sp_change_secondary_role (Sv2)

3) Change the monitor role by running sp-change_monitor_role (Sv2)

4) Resolve the log ins - (Sv2)

5) Now I want to fail back - I copy the TRN files to Sv1 - use SQL Ent to restore the database at point in time. The task is done; however, the database is still mark as loading. I could not use sp_dboption.

I appreciate any suggestion.

Thanks in advance
