database msdb cannot be opened due to inaccessible files or insufficient memory or disk space - in recovery pending status

August 24, 2009, 10:03 am

came in this fine monday morning and it looks like developers were running some kind of trace that filled the primary DATA folder with about 80,000 5mb trace files.  now that process has stopped and the logfiles have been cleaned up, but when attempting to connect to the server using the management console i get the error:

Database 'msdb' cannot be opened due to inaccessible files or insufficient memory or disk space.  See the SQL Server errorlog for details. (.Net SqlClient Data Provider)

when i check the status it is in recovery pending mode.  i have a backup from yesterday but im not sure if this database became corrupt before that backup or not because this process was ongoing over the weekend.  the last timestamp on the msdb and log files is 7am this morning.. 

I am not sure how to proceed recovering the msdb database with limiting interruption to the users.  any advice is extremely appreciated.  this is sql server 2008.  i can login via sqlcmd and see it is in recovery pending status:

1> select state_desc databasestatus_sysdtabase from
2> sys.databases where name ='msdb'
3> go
select state_desc databasestatus_sysdtabase from
sys.databases where name ='msdb'

Hi,

 I know that I used to see Windows events (App/Security/System) logs under SQL Server error log viewer along with SQL Agent logs & Database mail logs. But recently I observed that I don't see Windows logs anymore.

 Do you know how to get them back to view Windows logs under SQL log viewer?

BulkCopy Issues with SQL

March 10, 2015, 11:15 am
$

Hello everyone, my question is in regards to a bulkcopy insertion in sql. 

My Table is very simple: 

ID (uniqueidentifier, set as primary key) 

Data (nvarchar(MAX)) 

INDEX: On ID (clustered, unique, hosted on primary key) 

I'm running a small script in C# that uses a bulkcopy to take a massive amount of excel files (approximately 30,000 rows in each file) and copies them into the table. 

At first I was copying files insanely fast, and was very happy with the results. 

Here's a snippet of the current code for reference 

 DataTable ColumnData = new DataTable();
                    ColumnData.Columns.Add("ID", typeof(Guid));
                    ColumnData.Columns.Add("Data", typeof(string));

//Add Data

 try
                    {

                        using (SqlBulkCopy bulkCopy = new SqlBulkCopy("CONNECTIONSTRING", SqlBulkCopyOptions.TableLock | SqlBulkCopyOptions.KeepIdentity | SqlBulkCopyOptions.KeepNulls))
                        {
                            bulkCopy.BatchSize = 10000;
                            bulkCopy.DestinationTableName = "dbo.TestData";
                            try
                            {
                                CentralDatabase.Open();
                                bulkCopy.BulkCopyTimeout = 0;
                                bulkCopy.WriteToServer(ColumnData);
                                CentralDatabase.Close();
                                Console.WriteLine("Data Inserted.");
                                ColumnData.Rows.Clear();
                            }
                            catch (Exception ex) { Console.WriteLine(ex.Message); CentralDatabase.Close();  };

                        }
                    }
                    catch (Exception ex) { CentralDatabase.Close(); };

After about 15,000,000 rows of data however everything slowed down to a crawl. 

I'm certain it's coming from SQL, but I'm not sure where I can go from here.

Is it my index? Should I change it to a nonclustered type?

Hi Experts

looking for your advise on the following scenario

I have a database with one file in the primary file group (size 25 G), every 2 hours SQL Server agent job is fetching data into a temp table (#table) from a linked server, doing some updation and finally dropping the existing creating a new permanent table (tablename remains same, table size is about 500MB) in the database

drop table mypermtable
select * into mypermtable
from #myvaribale table

I want to isolate this object from others in a separate filegroup and looking for some solution to do it without changing any database level configuration like

ALTER DATABASE mydb
MODIFY FILEGROUP mynewgroup DEFAULT

secondly please advise, if frequent (every 2 hours) dropping table and recreating a table can make fragmentation in the datafile.

Scheduled Jobs and Server Maintenance

Hi All,

Running SQL 2012.  We have a series of scheduled jobs that run once per day, with no retry interval set.  I was informed by IT today that they need to perform unscheduled maintenance on the server this evening - which may or may not be completed by the time our jobs are set to run.  My question is: if a job is set to run at (say) 10pm, and the server is off - when it is restarted, does it try and execute this missed job?  Or does it just do nothing and next execute according to it's regular schedule (so, at 10pm the following night?)

Thanks.

On the SQL side I have used the following

EXEC master.dbo.sp_addlinkedserver
  @server = N'MYSQLSRV',

it comes back with

Database 'VERY DIFFERENT DB' cannot be opened because it is offline.

I know there is a database on this server that is offline, actually 2 or 3, but not the one Im trying to get information about.  What could cause the above query to have trouble getting index info that is caused by an entirely different database being offline?

performance monitor review for Sql server

Hi All,

Below I took the data from running a perfmon for 5 hours in one of our production environment.

Page Life Expectancy -> 600.444
%Processor Time -> 10.777
Memory Available bytes -> 26,816.746
Cache Bytes -> 747,683,581.828
Avg Disk Queue Length -> 424.858
Avg Disk Sec/Read -> .351
Avg Sick write/sec -> .780

From my understanding am not in any performance issues as.
Memory is ok -> As Available memory is 26,826 MB (We allocated 32 GB out of 64 GB to sql server)
Cache bytes is also ok
Avg. Disk read/write is less than 1 so it should be ok.
Avg disk queue length is high which is contradiction to the above so I think we might have some performance issue in disk processor time is normal.
PLE is 600 if am not wrong it's 600 secs which is 10 minutes so it's fair.

From this I believe my server is OK and there is no issues, except for Disk queue length, Please advise if my understanding is correct. If need more study also suggest me some articles am happy to learn.. :)

Thanks,

Event Notifications for Deadlock Graphs

April 12, 2012, 9:04 am

So, I was trying to setup emailing of deadlock graphs using event notifications. I followed the information I found in Jonathon Kehayias PASS information, but it appears (and maybe I am wrong) that event notifications and queues only work on the database you create them under??? I see it says in BOL: http://msdn.microsoft.com/en-us/library/ms189453.aspx that it applies to the instance, but when I manually create a deadlock, the queue only gets an entry if the deadlock was created accessing an object in the database where the queue was created. If I switch to another database, it does not add to the queue at all. Is that right? Or did I possibly configure something wrong? I can't believe that events would be restricted to only fire in the database scope of the queue. That just sounds like it would essentially make this tool kind of useless for broader scoping work, like, anything actually instance related. Does anyone know?

What permissions needed to view index statistics for a database?

Im trying to setup a job that will read index statistics about a given database.  The system management views are in Master.
Im trying to test the permissions for the login that will be used by doing Execute As, but Im getting permission errors such as
The user does not have permission to perform this action.  Also, since the login is a domain account mapped to a sql login, I cant simply login as that user to run the statement.

So what permissions would be needed to run the statement below?  I can run it without issue, but ive got Admin rights.  I really dont want to give this user admin rights

--Missing index count
SELECT @MissingIndexCount = COUNT(*)
FROM sys.dm_db_missing_index_groups mig
INNER JOIN sys.dm_db_missing_index_group_stats migs ON migs.group_handle = mig.index_group_handle
INNER JOIN sys.dm_db_missing_index_details mid ON mig.index_handle = mid.index_handle
INNER JOIN sys.databases db ON mid.database_id = db.database_id
WHERE migs.avg_total_user_cost * (migs.avg_user_impact / 100.0) * (migs.user_seeks + migs.user_scans) > 10
AND db.name = 'My Database Name'

Install second SQL instance onto existing cluster role

Hi,

We have a 3 node cluster running Windows Server 2012 R2 with 5 SQL clustered roles running SQL 2012 spread across them. For certain reasons we have a requirement to install a second SQL named instance onto one of the existing SQL roles. All of our SQL instances are currently running on different ports with no issues.

When we run the wizard to install the additional instance we specify the new instance name along with the existing network name to install to. However, we receive this error message:

"The SQL Server failover cluster instance name <existing role name> already exists as a clustered resource. Specify a different failover cluster instance name."

I am wondering if it is by design that it doesn't allow you to do this or a limitation of the GUI install? Is running multiple SQL named instances on a single cluster resource group/role supported?

Cheers

Problem setting up data collection for a performance problem

We have a performance problem on our production environment: there is a query that is long to display specially on specific records involving a lot of détails. I had the idea to set up data collection to investigate the problem.

I used the wizard to set up data collection with default settings.

I had created a database PERF_DW on our test server for that purpose.

I didn't have any problem with the wizard: it created data collection sets and SQL Server agents tasks and probably many objects. But I don't know where I missed something  but I didnt, have the chance to specify the database I wanted to tune and even when I started data collection, I couldn't figure out where were the reports.

Then I tought that I did it all wrong so I stopped data collection and dropped the database and tried to deleted the jobs created and I had the following message:

Now I understand that the collectors prevent the jobs from being deleted but I can't delete the collectors.

What should I do?

Any help is appreciated.

With 2008 - What would be the 'best practice' approach for giving a principal access to system views

March 13, 2015, 6:51 am
$

0

I want to setup a job that runs a few select statements from several system management views such as those listed below.  Its basically going to gather various metrics about the server, a few different databases and jobs.

msdb.dbo.sysjobs
msdb.dbo.sysjobhistory
sys.dm_db_missing_index_groups
sys.dm_db_missing_index_group_stats
sys.dm_db_missing_index_details
sys.databases
sys.dm_exec_query_stats
sys.dm_exec_sql_text
sys.dm_exec_query_plan
dbo.sysfiles
sys.indexes
sys.objects

So, there a number of instance-level permissions that are needed, mainly VIEW SERVER STATE
https://msdn.microsoft.com/en-us/library/ms186717.aspx

Granting these permissions to a single login seems like introducing a maintenance headache for later.  What about a server role?
Correct me if Im wrong, but this is a new feature of 2012 and above, the ability to create user-defined server roles.
Prior to version 2012, I will just have to settle for granting these instance-level permissions to individual logins.  There wont be many logins that need this kind of permissions, but id rather assign them at a role level then add logins to that role. Then again, there is little point in creating a seperate role if there is only 1...and maybe 2 logins that might need this role?
