SQL Server 2008 R2 and storage replication

Hello All !
On a Production site, I have a SQL Server 2008 R2 for a fat application. On a DRP site, I have the same SQL Server 2008 R2 fat application.
The production and DRP sites are interconnected with a physical SAN storage (synchrone replication). SAN LUNs are synchronous replicated (Data + logs).
In this case, is it necessary to keep logshipping beetween the 2 sites or the LUNs replication is sufficient ?
Thanks for advance for your ideas / help - Regards - Have a nice day ! RHUM2

<<In this case, is it necessary to keep logshipping beetween the 2 sites or the LUNs replication is sufficient ?>>
That question is impossible for us to answer, since we don't know your requirements (SLA etc). But if you re-phrase your question, we can give feeback with which you hopefully can make that decision:
What can log ahipping protect me from which SAN replication can't? I can think of a couple of things (others are free to chime in):
Corruption at the page level. SAN replication give you a binary image of the data. If a page is corrupt at site A, it will be corrupt at site B. Log shipping work by retorting transaction log backups.
Delayed log restore. If a problem happens at site A, you can decide to have delayed log restores at site be and restore a log backup until just prior to the accident.
Both above assumes that you know what you are doing have basically have planned for these things. But technically, they are examples of things that log shipping allows for.

Does SAP use SQL server's snapshot and transactional replication?

Gurus:
Could you help with this?
Does SAP use SQL server's snapshot and transactional replication?
Thanks!

Hi Christy,
no, SAP does not directly leverage these functions.
But none the less, it is up to you to use these on your system. I regulary use the snapshot functionality when applying Support Packages. In case somehing goes wrong a snapshot is the easiest way to roll back the import process (not exactly the best choice when talking about production and users keep on working while importing).
Have a look at this [document |http://download.microsoft.com/download/d/9/4/d948f981-926e-40fa-a026-5bfcf076d9b9/SAP_SQL2005_Best Practices.doc]. It deals with Best Practices and also covers snapshot, replication and mirroring.

Understand SQL Server 2008 R2 replication features for a reporting database

Hi, I am using SQL Server 2008 R2 and working on building a reporting database using transactional push replication and want to know the downside that we should aware of using this.
For instance, is the data always available to the users even when changes are being written from the publisher?
I am also interested in learning replication mechanism & internals. How should I proceed?
Thanks in advance........

SQL Server 2008 R2: which version of Visual Studio do I need to keep database projects and SSIS projects in the same solution

I need to build a solution containing a database project and an integration services project for SQL Server 2008R2. Apparently, the subset of Visual Studio tools that comes with SQL Server 2008R2 does not include database projects and does not have
Team Foundation Server support. Because of those limitations, I am trying to determine which version of Visual Studio will allow me to:
1. Build a single solution that includes both a database project and an Integration Services project
2. For the database project, be able to import a database schema from an existing SQL Server 2008 R2 database, do schema compares and update the project from the database and vice versa
3. For the Integration Services project, be able to deploy the packages to SQL Server Integration Services on SQL Server 2008 R2 (that is, to the msdb database).
4. Use Team Foundation Server for source control of the whole solution, including both project types.

Hi G Britton,
To build a solution containing a database project and an integration services project for SQL Server 2008 R2 and use Team Foundation Server for source control.
You can choose to install Visual Studio 2008.
And as you want to utilize Schema compare and/or Data compare functionalities in Visual Studio, you will need to install the
Visual Studio Team System 2008 Database Edition or Visual Studio Team System 2008 Team Suite.
In addition, for Visual Studio issues, I would like to recommend you post the question in the
Visual
Studio forums to get better support.

Team Foundation Version Control
Compare and Synchronize Database Schemas

Upgrade sql server 2008 to 2008R2 and apply Service pack 3

Hello,
I have a two node cluster (sql server 2008). I would like to upgrade to SQL Server R2 and at the same time would like to patch to Service Pack 3. What would be the best way to accomplish this task with minimal downtime to the users?
This is my plan:
1. Detach any read only databases.
2. Upgrade to 2008 R2 (shared feature only) on passive node (node1).
3. Apply SP3 on passive node in step 2.
4. Swith active node to passive node (node2).
5. Upgrade to 2008 R2 (shared feature only) on node2.
6. Apply SP3 on node2.
7. Upgrade db (instance) on node2 to 2008 R2.
8. Upgrade db (instance) on node1 to 2008 R2.
9. Re-attach read only databases.
Is my procedures correct?
Thank you.

Backup Restore With SQL Server 2008 R2 although it succeeded with SQL Server 2008

Dears;
I have a Full backup of some DB of around 417 GB within SQL Server 2008 R2 , and when I tried to restore it , i get stuck several times with the error below :
Restore failed for Server (Microsoft.SqlServer.SmoExtended)
A system assertion check has failed. Check the SQL Server error log for details. Typically, an assertion failure is caused by a software bug or data corruption. To check for database corruption, consider
running DBCC CHECKDB. If you agreed to send dumps to Microsoft during setup, a mini dump will be sent to Microsoft. An update might be available from Microsoft in the latest Service Pack or in a QFE from Technical
Although I have restored
successfully other several Full+ Deferential backups for the same DB while it was in SQL Server 2008 not 2008 R2.
And so I have rounded all different possible assumptions for such common know error by Microsoft for SQL Server 2000, 2005, 2008 but
no way as next:
1-
I have attempted to restore it within 2 environments clustered and non-clustered of SQL Server 2008 R2.
2-
I have attempted to restore verify it and it was so fine .
3-
I have attempted to restore it using Continue_after_error ,no_checksum but no way.
4-
I have attempted to move Backup file to another Storage but no way.
5-
I have scheduled jobs to DBCC
Checkdb the live DB and it wasn’t any errors since long time right now
6-
I have also DBCC check all master +msdb+model+Tempdb ,and they are so fine
7-
I have also checked all I/O subsystem of SAN and Network controllers , but they are fine evidenced much more by my trial on 2 different environments.
8-
I have also checked Memory and it is so fine all the time since I have 128 GB memory and I control it also so well.
For DB Design +Structure :
It has 20 Files containing tables partitioned horizontal +Vertically
(Schema Partitioning +File Stream partitioning ) through these 20 files.
I have Data compression of the required tables only.
I have one table of more than 300 GB alone which is partitioned as mentioned above.
I have implemented Read Committed Snapshot isolation level using row versioning integrated so well with File stream technology since it is a new feature of SQL 2008 R2.
DB is in simple recovery model for garbage collection of all file stream data as a result of much Delete /update in images themselves.
So any one has any idea about such case..How to solve it…?

Filtering extended event in sql server 2008 r2

This code has been generated in sql server 2012 (using the graphical interface).
CREATE EVENT SESSION [backupsmssql] ON SERVER
ADD EVENT sqlserver.sp_statement_starting(
ACTION(
sqlserver.client_app_name,
sqlserver.client_hostname,sqlserver.nt_username,
sqlserver.session_nt_username,sqlserver.sql_text,
sqlserver.username)
WHERE ([sqlserver].[like_i_sql_unicode_string]([sqlserver].[sql_text],N'%backup database%'))
WITH (MAX_MEMORY=4096 KB,EVENT_RETENTION_MODE=ALLOW_SINGLE_EVENT_LOSS,MAX_DISPATCH_LATENCY=30 SECONDS,MAX_EVENT_SIZE=0 KB,MEMORY_PARTITION_MODE=NONE,TRACK_CAUSALITY=OFF,STARTUP_STATE=OFF)
If I try to run it on sql server 2008 r2, the filtering part seems to be misinterpreted and the following error is thrown:
Msg 25706, Level 16, State 8, Line 1
The event attribute or predicate source, "sqlserver.sql_text", could not be found.
If I remove the where clause, the statement runs fine even though the sqlserver.sql_text is returned as part of the actions. So obviously the "sqlserver.sql_text" is existant. Why would I receive a message it does not exists in the
where clause? Was the "like_i_sql_unicode_string" inexistent in 2008 r2 or has the syntax changed in 2012. How can we filter sql_text in 2008 r2? I can't seem to find any doc regarding this, help would be appreciated.
p.s. There is a very similar question here but it has been closed by the moderators and does not answer the question:
https://social.msdn.microsoft.com/Forums/sqlserver/en-US/76c2719c-ea02-4449-b59e-465a24c37ba8/question-on-sql-server-extended-event?forum=sqlsecurity

You are on the right track:
The differences in the available events and predicates (source and compare) between SQL Server 2008/R2 and 2012 are quite substantial.
So the LIKE-operator is not available at all under 2008/R2 as a comparison-predicate, and sql_text is also not available as a source-predicate - only as action itself. - One has to realize, that actions really are not automatically also predicates.
For a complete list of predicates you can query like this:
SELECT dm_xe_packages.name AS package_name,
dm_xe_objects.name AS source_name,
dm_xe_objects.description
, dm_xe_objects.object_type
FROM sys.dm_xe_objects AS dm_xe_objects
INNER JOIN sys.dm_xe_packages AS dm_xe_packages
ON dm_xe_objects.package_guid = dm_xe_packages.guid
WHERE
(dm_xe_packages.capabilities IS NULL OR dm_xe_packages.capabilities & 1 = 0)
AND (dm_xe_objects.capabilities IS NULL OR dm_xe_objects.capabilities & 1 = 0)
AND dm_xe_objects.object_type
IN ( 'pred_source', 'pred_compare')
ORDER BY dm_xe_objects.object_type
Unfortunately for your specific filter there is not workaround for Extended Events.
You would have to resort to another predicate for filtering altogether.
BUT: if you are on Enterprise Edition, why not use Auditing. There is a Audit-Group for Backup/Restore.
It would be really simple like the following:
CREATE SERVER AUDIT SPECIFICATION [Audit_BackupRestores]
FOR SERVER AUDIT [AuditTarget]
ADD (BACKUP_RESTORE_GROUP)
If you are on Standard, you found yet another reason to upgrade to a supported version of SQL Server, I am afraid to say..

Hello,
according to this article https://support.microsoft.com/kb/975090 the issue with deadlocks on query notifications should be fixed with SQL Server 2008 SP3 (10.0.5500.0). But we still get deadlocks in the following manner:

Hello,
SQL Server 2008 SP4 and all cumulative updates of SP3 do not have fixes related to deadlocks.
Maybe the following workarounds and solutions can help in your scenario.
http://stackoverflow.com/questions/3707137/understanding-deadlocks-with-sql-server-query-notifications
Deadlock Prevention. In case you need to lock multiple conversation groups in a transaction, you need to take the same order to lock the different conversation groups in all transactions, otherwise you will have a deadlock issues.

Problems with SQL server 2008 nvarchar type to varchar in oracle.

Hello
I did an Heterogeneous Connectivity between SQL server 2008 db and Oracle 11g, so far so good, but when i try to view colum data on RPD (only varchar type) i only see the first character of the string.
One more thing, when i try to see the data on Oracle SQL developer i get some strange characters, like when we have the wrong character encoding on our browser.
Some print to illustrate the problem.
Oracle SQL developer query:
http://postimg.org/image/5cvyqw6ih/
Microsoft SQL developer query :
http://postimg.org/image/skddx991f/
RPD printscreen :
http://postimg.org/image/aok2337cp/
SQLplus (as you can see the are spaces between the characters ) :
http://postimg.org/image/664xw1xjh/
To finish the data will be use to build an mobile app with oracle mobile app designer.
Thank you

The spaces you see between the characters when using the gateway indicate a wrong charset is being used.
1. Which gateway are you using - DG4MSQL or Dg4ODBC?
2. Could you please post the gateway init file and just in case it is DG4ODBC also the odbc.ini file
3. What's the character set of the Oracle database?
4. Looks like you're connected using Putty to a Unix box - what is the Putty NLS setting?
5. What is the NLS setting when starting SQL*Plus and what is the LOCALE setting?
6. Was a NLS_LANG parameter set when the gateway was started? Please change in your gateway init file the HS_FDS_TRACE_LEVEL to DEBUG, then run again the query and post it to a share.
=> There's a note that guides you step by step to configure the gateway and your env correctly - please have a look at:
