Sql server cache file

I dont understand what is this cache file and its size goes on increasing.Could somebody tell me in detail what is this cache file and what is use of this

Hi sunj15,
Are you referring to the cache files located in the TEMP directory such as machine-name_instance.SQL-Server-name_{49268954-4FD4-4EB6-AA04-CD59D9BB5714}_#.cache?
If that is the case, these cache files are created by data collection functionality of SQL server. SQL Server Management Data Warehouse (MDW) provides two ways of collecting data: Cached mode and Non-cached mode. Cached mode stores the Collection Set data
in a .cache file in the cache file directory which is uploaded to the MDW database based on the schedule that you defined for your Collection Set.
When the .cache files become very large, we can perform the following steps to solve the issue.
1. Change the Server Activity collection to non-cached.
2. Increase the collection frequency.
3. Modify the sp_purge_data stored procedure for the purge job to run faster.
Besides, for other type of SQL Server cache, please review this
blog.

SQL Server 2008 Management Data Warehouse
Cache files–Why are you increasing in size?

Calling SQL Server Script File in Hypersonic DB

HI All,
I am using Hypersonic Database with java swing.
To update the database, i am getting SQL Server script file through a webservice.
The problem is i dont have any idea, how i can update Hypersonic Database with the SQL Server script file.
Please Help.
Thanks
Nitin

Also I think
CREATE TABLE table1
( tableoneid INT PRIMARY KEY NOT NULL
, name VARCHAR(255) NOT NULL
, PRIMARY KEY(tableoneid) );should probably be
CREATE TABLE table1
( tableoneid INT CONSTRAINT table1_pk PRIMARY KEY
, name VARCHAR(255) NOT NULL );otherwise you specify the primary key twice (and PRIMARY KEY implies NOT NULL so the NOT NULL is redundant).
Then TABLE2 might need to be something like:
CREATE TABLE table2
( tabletwoid INT NOT NULL
, tableoneid NOT NULL CONSTRAINT table2_table1_fk REFERENCES table1
, CONSTRAINT table2_pk PRIMARY KEY(tabletwoid, tableoneid) );although the table-level constraint syntax could be used for the foreign keys if it meant less editing of your scripts. The "CONSTRAINT constraintname" clause of constraints is optional but recommended, as otherwise they will get system-generated names like "SYS_C005157". (Note that if you specify the FK inline as part of the column definition you do not need to include a datatype.)
If the IDENTITY clause causes a sequential value to be assigned as a default, there is no direct equivalent to that in Oracle. The nearest thing would be a row-level BEFORE INSERT trigger.

System Center 2012 R2 install: SQL server Data file and log file

This might be a dumb question, but I can't find the answer anywhere.
I'm installing a new instance of System Center 2012 R2 on a new server, I'm stuck on the SQL Server data file section. Everytime I put in a path, it says that tne path does not exist. I'm I supposed to be creating some sort of SQL Server
data file and log file before this installation, I didn't get this prompt when installing System Center 2012 SP1 or hen I upgraded from System Center 2012 SP1 to System Center 2012 R2
My SQL is on a different server
Thank you in advanced

Have you reviewed the setup.log?
On a side note, why would you put the database file on the same drive as the OS? That defeats the whole purpose of having a remote SQL Server. Why use a remote SQL Server in the first place.

C# application to execute both oracle and sql server script files.

Hi All,
I am suppose to develop an application using c# which can execute oracle script files as well as sql server script files based on some user's choice.
Both the script files(oracle/sql server) contains scripts to create tables, create views and create functions.
What is the best way to do this and which existing c# functions should is use.
Thanks in advance.

I am suppose to develop an application using c# which can execute oracle script files as well as sql server script files based on some user's choice.
You can use SQL Plus for Oracle. You can have a C# program that issues commands for scripts for table, views, triggers creation and the whole 10 yards to SQL Plus,
http://docs.oracle.com/cd/B19306_01/server.102/b14357/qstart.htm
https://www.google.com/#q=sql+plus
I started writing a program to use SQL Plus to run the scripts, but cI ame to the conclusion that it was a waste of my time.
A tool called OSM, an Oracle, tool gives a list of script files that need to be run do to a change in a script file based on file timestamp. You can copy the list doing a copy/past operation and drop it into SQL Plus's Command line, and SQL Plus runs the
scripts.
For MS SQL Server, you have this, which you can run from a C# program too.
http://www.webfactory-world.de/wfknowledgebase/wfknowledgebase_wf3.3/Content/AdditionalWindowsSettings/Tutorials/UpdatingSQLDBFromCommandLine.htm
I would consider using the above from a C# program a waste of time too.
I look at it this way. If the user doesn't have database admin experience and know how to use DB admin tools, then they have no business doing anything with a database - period.
BTW, the Invoke statement in VB or C# will run SQL Plus or SQL Server command line tool.

Migrate sql server dump file to Oracle database on a network

I have a sql server dump file provided to me by DBA's. I have to migrate this dump file to Oracle database on a network. Please suggest me the steps to do this.

regardless of the tool/technique you use, those bits have to get from machine running sqlserver to the machine running Oracle. Either over the network (through the firewall) or via 'sneakernet.' What, exactly, are the firewall constraints?
If the export is a simple text file (character delimited fields? fixed length fields?) and only 100 records ... Migration Workbench may be overkill, perhaps a simple sqlldr job. But you still have to get the bits from 'there' to 'here'.
============================================================================
BTW, it would be really helpful if you would go to your profile and give yourself a recognizable name. It doesn't have to be your real name, just something that looks like a real name. Who says my name is really Ed Stevens? But at least when people see that on a message they have a recognizable identity. Unlike the system generated name of 'ed0f625b-6857-4956-9b66-da280b7cf3a2', which is like going to the pub with a bag over your head.

Designer10g R2 Design Capture of SQL Server DDL file Failed

I have been using Designer 10g R2 to design capture Oracle Database Schema into the Server Model Diagram with no problems at all.
I have a SQL Server 2005 exported DDL file into an ASCII text file. I then import the DDL script into the Server Model Diagram but ERRORs.
I use SQL Server 2005 to import the DDL script and then create an ODBC to connect to the SQL Server. I can then design capture the SQL Server schema into Designer.
What has gone wrong? Does Designer 10g R2 support design capture from SQL Server DDL file directly to Designer?
By the way, if I want to generate MySQL DDL script or design capture MySQL DDL script into Designer, how could this be done as there is no ODBC driver for MySQL?

Using flash to display images from sql server or file system

hello,
what methods and parameters of the urlloader class we have to use to display images in a flash player if possible..
also movie should update everytime a new image is added to a database or file
the images can either be in a file system or in a sql database (if possible)
does flash comes with an object of this type or we have to create it.
regards,

i responded to your duplicate message 4 days ago:
is it possible to insert and retrieve images from sql server using actionscript.
you'll need server-side script to query your database and you can use the flash urlloader class to call your script.
also is it possible to create a flash scrolling gallery based on images stored in a database and everytime an image is added it is displayed in the gallery.
load the data using the urlloader class and then load the images. periodically query the database for new images if there's no direct way for flash to know a new image was added.

Repeated Errors in SQL Server log file

I have hundreds of these errors saying 'Login failed for user 'Reporting' The user is not associated with a trusted SQL Server connection [CLIENT: ip address]
The ip address is that of the server that sql server is installed on.
Looking in my log file, all looks good until I get to Service Broker manager has started, then I get Error: 18452, Severity: 14 State: 1 then these two lines repeat about every minute, for the last 3 days!
I think I must have just missed a tick box somewhere, but where?
I have been into one of the databases, and input and checked data, both via an application I wrote and SQL Server Management Studio.
I am also having trouble connecting using my application to connect to the database, I can only connect if I use a Windows administrator account (this SQL Server 2005 running on a Windows 2003 Server, with the app on PC running Windows 2000)

Hello Graham,
did you find any solutions for that problem? I'm discovering a similar problem. The state of my error message is 5. According to the following source http://blogs.msdn.com/sql_protocols/archive/2006/02/21/536201.aspx this means the user is not known. This is correct. Neither the SQL-Server nor the Windows system has such a userid.
The faulty user name is 'Reporting'. What is that user used for? I have set up other SQL Server 2005 servers but was never asked for such a name.
Greetings,
Frank

SQL Server log file

We are facing one issue can anyone please help me out.
Logs are getting full in below path . Can we remove the logs ? is it archive logs ?
Path : H:\Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL\DATA

If T-Log backups are configured then the log automatically get truncated once backup is compelted. If you dont have backups configured and you dont want to save the transactions you can manually truncate it
Hi,
From SQL Server 2008 onwards truncate_only is removed, it is replaced by
backup log db_name to disk='Null'
Also if your log is growing AND YOU DONT NEED POINT IN TIME RECOVERY switch recovery model to simple it will force checkpoint and logs will get truncated( If transaction does not requires the log) . Avoid using backup log to null or truncate only.
Swapna,
>>Also if you dont want the transactions to be saved then you can set the recovery model and Simple
This is incorrect language used saving/committing transaction does not depends on recovery model. Recovery model only controls logging and recovery. if transaction is committed it will be present in database no matter what recovery model you use.

Connecting to a local SQL server .mdf file

Hi all,
In doing some prototyping of my database I started working with a local copy of an SQL Server database since it so conveniently integrated with the Visual Studio .NET tools I use. Now that I have spent far too much time working on a local prototype, I would very much like to migrate it to our in-house database rather than rewrite the whole thing (it is quite large in terms of tables and constraints and none of our in-house tools generate code from ER diagrams).
Seeing that SQL Developer had a migration utility I pounced at a chance to use it. I installed it as well as the recommended JDBC driver; however, it occurs to me that I have no idea how to connect to a local database file using the host name and port fields given to me. Is there some convenient way to configure SQL Server 2005 to forward this file to some kind of local host? Or is there any other driver for use with a local .mdf file? Help would be greatly appreciated.

While it does come with a copy of SQL Server with it, visual studio suspiciously just asks for a file name, so I would assume it reads directly from the .mdf
I have a copy of SQL Server 05 on the machine, but I haven't done anything in the way of server side configuration before, so I can't even guess how to direct it to serve the file.
All software packages involved are:
Windows XP
SQL Server 2005
Visual Studio .NET 2005
SQL Developer 1.5.1
Oracle client 10g connecting to an Oracle 9i release 2 server
Any pointers to the right direction or alternate migration solutions would be great.
Edit: I am highly suspicious that Visual Studio was connecting to this file through SQL Server Express and not my standard edition copy, and it is therefore not attached to the database, the solution is not looking entirely easy, so an alternate migration may be a better choice. Thanks in advance for any help.
Edit: Well my suspicions were confirmed. I attempted several solutions. First of which being the MS SQL Express publishing wizard so that I could publish to SQL and run the script via Toad or SQL Plus; however, it only targets MS SQL Server 2000 or 2005 which would result in a lot of hand editing in terms of migration. Attempting to find a script converter did not help as they all either failed outright or demanded a connection to the datbase via ODBC or JDBC (which doesn't support SQL Express' less than clever attach on connection ideas). This led me to the alternate solution of trying to attach the file to my main database and connect to it; however, the SQL Server command prompt has some sort of permissions issue with my office security setting (though I can edit files fine) and results in failure.
I think it is about time to throw in the towel and just work it out by hand. This would be greatly expedited by any visual database tools that generate code from ER diagrams if you happen to know of a freeware solution. We lack an internal copy of Oracle Designer and the free license only permits a single prototype. So any suggestions on the front of freebie visual object relational tools and alternate migration ideas would be of great help. Until then I'll be grinding through it with moderate dissatisfaction.
Thanks again.

SQL Server 2008 File Stream On Existing Table

Hi Folks,
I have enabled the SQL Server File Stream option on a Existing table.
1. Created a GUID Column
2. Created a File Stream Column
3. Swapped the Blob Column information into file Stream column.
4. Dropped the BLOB Column.
I could evidence, The above Step 3 Process moved out all the Blob Data into an configured Network File Group.
Ex:
Existing BLOB Data Size --> 10 GB
Once after the completion of above step 4, SQL Server is not freeing up the BLOB occupied Space 10 GB. It should have only few MB's pointer address to the network file Group?
If we create a new table with File Stream data type and insert the existing BLOB data ,Will result few MB pointer Address occupied in the newly created table. We except the similar behaviour for updating BLOB to File Stream in existing table.
Please advice me.
Thanks
Narendran

When you drop a column, SQL Server only mark the column as dropped, but does not reclaim the space, as that requires data to be shuffled around. You need to rebuild the clustered index (and any other index with the column) to reclaim the space. See repro
below:
CREATE TABLE myblobbie (id int   NOT NULL PRIMARY KEY,
name sysname NOT NULL,
blob varchar(MAX) NOT NULL)
go
INSERT myblobbie(id, name, blob)
   SELECT object_id, name, replicate(convert(varchar(MAX), name), 1000)
   FROM   sys.objects
go
EXEC sp_spaceused myblobbie
go
ALTER TABLE myblobbie DROP COLUMN blob
go
EXEC sp_spaceused myblobbie
go
ALTER INDEX ALL ON myblobbie REBUILD
go
EXEC sp_spaceused myblobbie
go
DROP TABLE myblobbie

Sql server data file and log file

hello experts
what is the best way to save data file and log file in a two node cluster environment. i have an active\passive cluster with windows server 2008r2 enterprise and sql server 2008r2. i am new to the environment and i noticed that all system and user databases
including their data and log files are stored in one drive, just curious, what is the best practise in such kinds of scenario, thank you as always for your help.

Make sure you have valid/tested backup strategy for both system and user databases.

How to design SQL server data file and log file growth

how to design SQL DB data file and log file growth- SQL server 2012
if my data file is having 10 GB sizze and log file is having 5 GB size
what should be the size in MB (not in %) of autogrowth. based on what we have to determine the ideal size of file auto growth.

It's very difficult to give a definitive answer on this. Best principal is to size your database correctly in advance so that you never have to autogrow, of course in reality that isn't always practical.
The setting you use is really dictated by the expected growth in your files. Given that the size is relatively small why not set it to 1gb on the datafile(s) and 512mb on the log file? The important thing is to monitor it on an on-going basis to see if that's
the appropriate amount.
One thing you should do is enable instant file initialization by granting the service account Perform Volume Maintenance tasks in group policy. This will allow the data files to grow quickly when required, details here:
https://technet.microsoft.com/en-us/library/ms175935%28v=sql.105%29.aspx?f=255&MSPPError=-2147217396
Also, it possible to query the default trace to find autogrowth events, if you wanted you could write an alert/sql job based on this
SELECT
[DatabaseName],
[FileName],
[SPID],
[Duration],
[StartTime],
[EndTime],
CASE [EventClass]
WHEN 92 THEN 'Data'
WHEN 93 THEN 'Log' END
FROM sys.fn_trace_gettable('c:\path\to\trace.trc', DEFAULT)
WHERE
EventClass IN (92,93)
hope that helps
