Would A TLOG File Size Change When Inserts/updates/deletes Are Not Involved?
Jan 3, 2008
I have a 14GB database whose data content is legacy and is described as static. The log file is significantly large and continues to change size mostly increasing by 2-5GB a day (~60GB now) I have observed over the past two days; it shrank once unexpectly by a few GB. The instance is hosting other databases such as: EnterpriseVaultDirectory, EnterpriseVaultMonitoring, EnterpriseVaultStore, and NetPerfMon - might these seemingly unrelated data sources be involved?
I am trying to a trace to find traffic against the tables, no such luck.
Web applications are playing against it for queries but there should be no UPDATEs beign applied. I can only suspect that other unknown applications are performing operations but have yet to find unexplained connections.
Are there any other reasons why this type of log file activity would happen merely due to queries or stored procedure calls?
Lets also state, "mirroring, indexing, replication" are not at play. I know logging "Full" is not necessary as "Simple" should suffice but I am still hunting down why UPDATEs might be getting through. I realize I might adjust the migrated SQL 2000 security model to deny updates to find what breaks but would rather not take that iniative yet.
The installation is a fresh SQL 2005 Standard setup with SP2 applied; the databases were upgraded.

I have transactional replication set up between two SQL Server 2000 databases. In some cases when I perform an UPDATE on a published table on the the publisher, SQL Server attempts to perform a DELETE followed by an INSERT on the subscriber using the stored procedures created during the initial snapshot.
Why does it do this?
How can I stop it doing this and force an UPDATE on the publisher to call the UPDATE procedure on the subscriber?
Thanks

Ok, I think this may have a simple answer. Basically I have no problems in setting up QueryString/Control/etc parameters when I use SELECT in the Configure Data Source Wizard as it prompts me for the necessary parameters. But when I try to use the Configure Data Source Wizard with an UPDATE, INSERT or DELETE it does NOT prompt me for the required parameters.Is this a bug or am I just missing something? Do I have to put them in manually or something?Thanks!

Hi all,
This managed application was written to run on a Symbol 3090 Win CE 5.0 scanning device. We are using the symbol provided classes to access the scanning interface, and SQL Compact database on the device to collect the scanned data, and then using merge replication to synchronize scanned data when the device is docked. The problem we have experienced seems to be releated to the performance when inserting and updating records in the database.
We have tested some randomly generated 1000 records and inserting/updatating into a database. At first the time to commit a record increases when the database is flushing into the memory (The flush interval in the connection string property is 10 seconds by default). and then as the database size grows increasing the time to commit every single record which is causing the application to perform slowly as they scan items into the database. However, the device program memory remains consistant as they are scan items. From our tests, I found the time to execute either a update/insert command on 2MB sqlMobile database (upto 10000 records, depending on the size of the columns) is taking nearly 2 to 2 and half seconds to complete. Below is the only code I am executing,
If Not sqlObj.UpdateItem(1061022, itemNo, 1) Then
sqlObj.InsertResultSet(1061022, itemNo, itemObj.Style, itemObj.Color, itemObj.Size, itemObj.Description, 0, 1)
End If
For the notes, I am using prepared updated command and resultset.insert methods to perform update and insert commands into the database.
Any help on this issue is highly appreciated.
Thanks
Ravi.

SQL 2K - SP3a - Development BoxThe environment is a piece of garbage ... triggers firing triggers firing triggers. Application is a piece of garbage that a developer want to make better (yea!) I need to put together a profile template to capture inserts and deletes into two tables. Not asking for the fish (but will accept it if necessary). Looking thru BOL, cannot find find an event class to capture insert and / or delete. Looking at TSQL event class gives SQLStmtCompleted event, and maybe I can filter on the two object IDs (object name not available because dbname not available as data column for this event.) Or if exists, but not documented, the event class for insert and delete. Any ideas?

Microsoft article Q142480 states "Triggers cannot be used to perform cascading updates and deletes if ForeignKey-to-PrimaryKey relationships have been extablished using SQL Server's DRI."
Does this mean that I cannot declare FK's in my scripts if I want to have triggers in the table? Do I just add a column in my table that will have a foreign key in it, but just not reference it in my script? Can someone clarify for me?
Thanks,
Nathan

recently i noticed that my trans Log size is not increasing(it is constant) , but the databse size is increasing at high speed.
why is it so? earlier the reverse used to happen i.e databse size increased only after a certain period. and log size increased at const. rate.

Hi...
I have data that i am getting through a dbf file. and i am dumping that data to a sql server... and then taking the data from the sql server after scrubing it i put it into the production database.. right my stored procedure handles a single plan only... but now there may be two or more plans together in the same sql server database which i need to scrub and then update that particular plan already exists or inserts if they dont...
this is my sproc...

Hi
I have 3 table (tbl1, tbl2, tbl3).
tbl1 colums ---Pid(autonNumber),Pcode(unique values),PGuid
tbl2 columns---Pid, CatId,Fid
tbl3 Colums----Pid,BundleId
Using Trigger(After Insert) in tbl1 to insert the data of tbl1.Pid to tbl2.Pid and tbl3.Pid . tbl1 will be uploaded with new rows and existing rows will be updated from the csv file.
Trigger in tbl1 works fine by inserting data to tbl2.Pid and tbl3.Pid.
My questions are :
1. Is it possible to use trigger to update tbl2 and tbl3 if records exist if not insert new record to colum Pid in tbl2 and tbl3 from Pid of tbl1
2.Or is it possible to use sql procedure to do cascaded updates or inserts by merging datasets from tables and csv file using asp.net
3.Or How can I use single Trigger to insert if not exist and update if data exist.
4.Or Do I have to use two trigger one for insert and one for update. If this is the case how do check for data existance.
After insert Triger I am using at the moment is below (replied as an answer in this forum for my previous thread)
create trigger t1 on tbl1
after insert
as
begin
declare @id int
select @id=pid from inserted
insert into tbl2(pid) values(@id)
insert into tbl3(pid) values(@id)
end

Hi All,
I'm a relative novice on SQL Server and am a complete beginner at SQL, so am looking for a little help.
I currently use a DTS package to perform inserts / updates to a "production" table.
The DTS package transforms a comma separated file into a "temporary" table that is truncated / cleared before the load starts.
The temporary table has a column denoting Insert or Update. The production table is almost identical, however, doesn't contain the Insert / Update column. The DTS package then, depending upon the Insert / Update flag, either inserts data into the production table or updates data in the production table.
When the DTS package has completed, I'd like to be able to run an SQL Query that validates everything in the "temporary" table is identical to that in the "production" table, which it should be.
I have managed to do some queries to verify that everything has loaded / updated i.e. select primary_key from temporary table where primary_key not in (select * from production table), however, what I haven't been able to do is verify that all the columns on the temporary table match the values in the production table (excluding the Insert / Update flag).
I tried concatenating the columns in each table and comparing the concatenated values, however, this failed due to the different data-types, i.e. decimal, text etc.
Any help will be greatly appreciated.
Many thanks.
Cheers,
David

I am looking for pros and cons for the following scenarios:
When a table contains a unique key constraint is it viable to always do an insert and immediately check the @@ERROR value and if @@ERROR states a duplicate key exception then perform an update statement?
Another possible solution would be to always check if the key exists and then do the insert / update based upon that result. This method will always require two steps.

Hi:
We have a weird problem in our test SQL 2005 SP1 - Windows 2003 Enterprise SP1 - Server (after upgrading from SQL 2000).
While changing data via JBOSS - JDBC connection, we get all our data modifications rolled back.
Selects are fine. Same SQL 2005 Inserts/Updates through JBOSS are fine on other machines with Windows XP (JBOSS is on the same machine there, while in troubled configuration it's on its own server).
But in production imitation environment we can't modify data.
Please advise where to look for the solution.
Thanks.

Hello people!Here is the situation:We have an old propriatary database that is used for daily tasks. Not much we can do with it, but we have to use it.I can create basically a read only connection to it through ODBC.I would like to, on a timed interval copy certain data for reporting from this slow thing to my SQL server so that I can learn to program, and create some cool reports etc without having to wait on this server all day.So here is what I don't quite understand.I had originally planned on just deleting the contents of the tbl on my SQL server just before I populated it each time, but found out that my AutoNumber field will continue to increase, and I'm assuming that eventually I'm going to run into a problem as a result.Should I be doing some kind of update instead? if so do I need to first CHECK if the record exisit, if not then do an insert, if so do an update type thing?Or is there a way to basically do it in one command?I hope this makes sense. I would show you some code but there really isn't much to show you other than my insert statement :->Thanks for any advice!Josh

Hopefully someone can at least point me in the right direction for moreresearch (e.g.: correct terminology). My only previous experience was justdumping data into a database using ODBC, and that was some years ago so nowmostly forgotten.I need to write an NT Service/Application (in C/C++) that will be gettingdata sent to it via SQL Server 2000. The data will arrive in my SQL Server(read-only access), via replication of tables from another remote SQLServer.My application needs know when new row are inserted, or updated so it can toread this data (needs to be quick/timely so hopefully no polling) to theninterface with other remote proprietary systems.T.I.A.PS: If you can recommend appropriate books on SQL Server 2000 that wouldalso be useful.

I have a database I need to copy from a Prod server to a Dev server. There is not enough space on the Dev server. In looking at the size of the files on the Prod server, the Initial Size property for the transaction log on the Prod server is set to 100,000 MB though the log is using nowhere near that.
This is a mirrored database so the recovery model is "full". I know that to change the initial log size, I have to put the database in 'simple" recovery model. Is this possible? Can I just:
1. Pause the mirror
2. Switch recovery model to simple
3. Change the initial size property to something smaller.
4. Shrink the transaction log
5. Change the recovery model back to full and resume the mirror?
I honestly don't know if the transaction log is needed on the Dev server. Meaning I may just be able to restore the transaction log to a different location on the server and delete it so that new one is created.

I have H Drive with 12 GB size.
The Transaction log file of my Database is given in H drive.
i.e H:Krishna_log.LDF.
My database initial setting for the Krishna_log.LDF is 10 GB.
so currently I can see 10 gb file occupied in the H Drive.
very soon my database Krishna_log.LDF is going to increase 10%.
Even though If do Backup/Shrink, it will reduce to the initial to 10 GB.
So all I need is, change the initial size of the
Krishna_log.LDF from 10 GB to 5 GB.
Pls give your suggetions...(I dont mind to shutdown,Restart the Sql server do these changes to achive this Task).
Thanx in advance.

Hi,
I have the following problem: Within a VBScript, I use a component (written in C++ I think with use of ADO) for sending "Insert", "Update" Statements to an SQL Server 2000 for inserting, updating data. If I insert 100 - 120 Records in a Loop, all works fine. If I insert 1000 records, approximately 150 records will be inserted very quick, then the program pause fo approx. 8 - 15 minutes and then it proceed for the next 150 recs, pause for 8 - 15 minutes and so on.
If I use a SQL Server 2005 for the database, all works fine. The same happens with another customer and another program written in Visual Basic 6.0 with ADO. The access to SQL 2000 pause and with SQL 2005 all works fine. It seems to me that this is a problem with some buffers, timeout, or so. Has anyone an idea on what screw I can turn?
Thanks

I am considering some disaster recovery scenarios.
Lets assume my MDF is gone - the disks are dead.
The LDF is on a different disk channel. Lets assume its fine.
Can I make a "final" TLog backup from the "good" LDF file?
Maybe copy some-earlier-MDF file into place, would that enable a TLog backup from the LDF file?
'Coz if I can then I could use that as a route to getting a zero-loss recovery - make a final TLog backup, and then restore the whole lot from last FULL + All TLog backups thereafter.

We have a SQLServer 2005 Enterprise merge replication publication with SQL Mobile 3.0 subscribers (Windows Mobile 5.0 and 6.0). We do not use pre-computed partitions due to trigger performance issues with an SSIS/ETL application that supplies data to the merge database. We do use the "Optimize" (=true) option, though we have tried this both ways with no significant differences. We use filters and joins for each worker ID (as HOST_ID) from the subscriptions.
The sync times become increasingly worse after we run the snapshot and bring the publication online. I have tried rerunning the snapshots, this helps little, as it often behaves like the subscription was set to reinitialize and forces a big sync (reload of all data) to the subscriber. We have tried much of the obvious (e.g., flattening filters and joins, adding indexes, etc.).
When users are synchronizing, we watch replication monitor and notice that a lot of time is spent processing "enumerating inserts and updates for article [any article]", especially processing the many generations and batches. This is true for any follow-up syncs after the 1st big sync (initializing the subscription).
I read several posts regarding the batches and generations of changes, and decided to try increasing the €śDownloadGenerationsPerBatch€?. I tried adding this parameter to the snapshot agent job, and the job fails each time with a vague message, even with the default value of 100. How do you change this parameter for SQLServer 2005 Enterprise?
Any suggestions?
Thanks in advance,
Matt

I've already shrunk the tlog from 350 GB to 313.My DB Server (2008 R2 Sp2) cannot be restarted and the db cannot go offline or detach due to company policy.My DB after changing from full to simple mode still has 313GB tlog file and when I run DBCC OPENTRAN I get Transaction information for database 'DB'.
Replicated Transaction Information:
Oldest distributed LSN : (0:0:0)
Oldest non-distributed LSN : (2882:26:1)
DBCC execution completed. If DBCC printed error messages, contact your system administrator.
Which means this DB is participating in a High Availability process like replication, mirroring or log shipping.
So I run EXEC sp_repldone @xactid = NULL, @xact_segno = NULL, @numtrans = 0, @time = 0, @reset = 1.
This is useful when there are replicated transactions in the transaction log that are no longer valid and you want to truncate the log.
But I get an error:
Msg 18757, Level 16, State 1, Procedure sp_repldone, Line 1
Unable to execute procedure. The database is not published. Execute the procedure in a database that is published for replication.
There are currently 9 connections and all are sleeping.What else can i try in order to shrink the tlog file?
