Error while installing SQL Server 2005 – Native Client cannot be found August 26, 2008

 

Recently while installing SQL Server 2005 Standard Edition on a “fresh” server I found that crazy thing just wouldn’t install!
I was getting the following error:

“An installation package for the product Microsoft SQL Server Native Client cannot be found. Try the installation again using a valid copy of the installation package ‘sqlncli.msi’”

Most cryptic… Considering my installation package is the disc given to me by Microsoft and I’m positive that the sqlncli.msi file is right there.
However, the actual issue appears to be as simple as an inability to upgrade an old Native Client edition.

 To resolve, use the Add / Remove Programs panel to uninstall an existing SQL Server Native Client installation and you should be good to roll.
Note that this appears to be common for other editions of SQL Server 2005 too.

Cannot detach a suspect or recovery pending database

Database in 'Recovery Pending' State -Error 945

After losing connectivity to the data and log volume for one of our SQL servers, we received the following error:

LogWriter: Operating system error 2
(failed to retrieve text for this error. Reason: 15100) encountered.

Which resulted in the database on that volume showing as being suspect.
After gaining connection back to the volume, I tried to detach the database, but received the following error:

Cannot detach a suspect or recovery pending database. 
It must be repaired or dropped. (Microsoft SQL Server, Error: 3707) 

To resolve i did the following:

ALTER DATABASE emergencydemo SET EMERGENCY;
GO

EMERGENCY mode marks the database as READ_ONLY, disabled logging, and access is limited to sysadmins. Marking the database in this mode is a first step for resolving log corruption.

ALTER DATABASE emergencydemo set single_user
GO
DBCC CHECKDB (emergencydemo, REPAIR_ALLOW_DATA_LOSS) WITH ALL_ERRORMSGS;
GO
ALTER DATABASE emergencydemo set multi_user
GO

This should resolve any corruption and bring the database online. The database will come out of EMEREGENCY mode automatically.

Enable “Ad Hoc Distributed queries” by sp_configure in SQL-Server 2005

If you want to use OpenDataSource or OpenRowSet query than you must have to enable “Ad Hoc Distributed queries”. It is disabled by default as a part of security configuration as per Microsoft.

You can set this option by two ways.

1.)    sp_configure command

2.)    Surface area configuration.

Since I am a script bee, I will explain steps for sp_configure.

You can run sp_configure to see current status of “run_value” field. If you don’t able to see “Ad Hoc Distributed queries” in the results set.  You have to enable “Show advanced option” by following command.

sp_configure ‘show advanced options’, 1

reconfigure
GO

You may get message

Configuration option ‘show advanced options’ changed from 0 to 1. Run the RECONFIGURE statement to install.

Once you are done with that, you can see “Ad Hoc Distributed queries” in list of sp_configure. You have to set “Run_value” to “1”. If it is “0” than run following command.

sp_configure ‘Ad Hoc Distributed Queries’, 1

reconfigure
GO

Which will show you following message.

Configuration option ‘Ad Hoc Distributed Queries’ changed from 0 to 1. Run the RECONFIGURE statement to install.

Using sp_configure

 

sp_configure is a system stored procedure designed to show and change server-level configuration settings on SQL Server. When executed without parameters, this procedure will enumerate the basic configuration settings on the SQL Server.

EXEC sp_configure

Results from sp_configure

These results show us 16 configuration options, however these are only the basic configuration options. There are also advanced options this procedure does not show us unless we change an additional configuration setting, named, ‘show advanced options’. Let’s do that now.

EXEC sp_configure 'show advanced options', 1 -- Changing to 1 turns it on

GO

RECONFIGURE WITH OVERRIDE

Now that we have changed this option, let’s execute sp_configure again and look at the result.

EXEC sp_configure

Now we should see upwards of 70 configuration options we are able to set on SQL Server.
In order to set them, we only need to copy the exact name listed in the ‘name’ column, and pass it as the first parameter for sp_configure, then for the second parameter, pass our desired value.

EXEC sp_configure 'Ad Hoc Distributed Queries', 1

GO

RECONFIGURE WITH OVERRIDE
