Transaction Logs And Microsoft ACCESS

Aug 9, 2004

here's a question i've always wondered the answer to,

you have a transaction log on sql 2000 which supposedly records all the sql commands (select, delete, insert, update) that are performed on your database.

now say you use ODBC and Microsoft ACCESS, you create a database file in Microsoft ACCESS with linked tables to your SQL Database via an ODBC connection.

now say you alter the data, maybe delete some records from that sql database using your linked table in Microsoft ACCESS

Would SQL 2000 (or any other version) record these actions in the log, even though the actions were carried out in Microsoft ACCESS? or has doing this completely negated the security offered by the transaction log feature?


do hope someone could shed some light on this, it's been bothering me for a while

Problem In Transaction With Microsoft Access Database

Apr 11, 2008



Hello,

I have microsoft access database. I want to use this database as source of SSIS transformation.
I have a data flow task which I want to get executed in Transaction with TransactionOption as "Required".

I tried using OLEDB datasource which uses oledb connection. I also tried using ADO.NET connection type with DataReader DataSource.

But in all cases at run time, it fires an error message as follows:
[DataReader Source [1]] Error: System.InvalidOperationException: The ITransactionLocal interface is not supported by the 'Microsoft.Jet.OLEDB.4.0' provider. Local transactions are unavailable with the current provider. at System.Data.OleDb.OleDbConnectionInternal.EnlistTransactionInternal(Transaction transaction, Boolean forcedAutomatic) at System.Data.OleDb.OleDbConnectionInternal.EnlistTransaction(Transaction transaction) at System.Data.OleDb.OleDbConnection.EnlistTransaction(Transaction transaction) at Microsoft.SqlServer.Dts.Runtime.ManagedHelper.GetManagedConnection(String assemblyQualifiedName, String connStr, Object transaction) at Microsoft.SqlServer.Dts.Runtime.Wrapper.IDTSConnectionManager90.AcquireConnection(Object pTransaction) at Microsoft.SqlServer.Dts.Pipeline.DataReaderSourceAdapter.AcquireConnections(Object transaction) at Microsoft.SqlServer.Dts.Pipeline.ManagedComponentHost.HostAcquireConnections(IDTSManagedComponentWrapper90 wrapper, Object transaction)


If I remove the transaction, the data flow task works perfectly fine.
Please suggest What mistake I am doing while connecting to MS Access database in side transaction??

The same mentioned configuration WITH TRANSACTION works perfectly fine for SQL Server AS SOURCE. Am I missing some very obvious thing??
Please suggest.

Can I create a second transaction log file for the DB and then delete the original log file?

What is the best way to do this for db's that are being replicated?

Jan 8, 2004

i have several sql servers doing maintenance plans and backing up the transaction logs to tape. unfortunately it seems that the server keeps adding the transaction logs to the same tape, without overwriting them. Nowadays a transaction log backup to disk takes 2 minutes but when done to tape it is taking up 1hr54minutes. What can i do so that the tape is automatically initialised without having to do it manually... Thanks

Hi, I know just about nothing about SQL Server. I am getting this error:The log file for database 'my_database' is full. Back up the transaction logfor the database to free up some log space.I can't access the transaction logs to back them up. I am told that my ISP'stech support should have it set up to shrink those logs automatically everyso often. Is that true?Why are they needed? Up till Monday, the logs are just of our getting SQLServer set up, so couldn't the logs just be deleted? Most of my site can'trun with this problem.I'd appreciate any enlightenment anyone can give me!Thanks, Jill

This seems like it'd be a really stupid question, but for the life of me Ihaven't been able to find an answer that works....I have a database that's approximately 400MB when shrunk... and thetransaction logs are at about 4.8GB when shrunk... I can't seem to get thetransaction log any smaller, no what I try. How can I get the log downbelow 1GB and keep it there? I've only got an 18GB hard drive and I need torun 2 copies of this database.-steve

SQL 7.0 Transaction Logs Won't Shrink!!!

Jun 5, 2002

I have seen quite a few people post this type of problem, but I am finding few solutions. Your advice and/or experiences are greatly appreciated.

Here's my scenario:

Environment: Windows NT 4.0 SP 6, SQL 7.0 (set up for Transactional Replication)

Problem: We have several remote dB machines configured for full recovery. On these machines are several dB's that are capturing aprox. 280 data points per second per unit. (Each dB represents one unit, and we have 21 units) No problem here. The problem is the transaction logs, that obviously grow profusely, will not SHRINK after, backups, dbcc commands and TSQL has been issued in failed attempts to shrink the logs. (in other words we've tried everything)

My questions are:

1. Because we are replicating, is it absolutely necessary to configure dB's for FULL recovery? How do I check in 7.0 if the dB is certainly in FULL vs. SIMPLE recovery mode?

2. I work with SQL 2000 and shrinking files is no problem. How can we shrink these log files in SQL 7.0?

It is rather urgent I find a solution as we are running out of hard drive space on our remote machines. Please help :-(

How Can I Move Transaction Logs?

May 4, 2000

Currently, my databases and their corresponding transaction logs are all on the same disk array. I finally was able to acquire a seperate disk, specifically to seperate the logs, in case of failure, etc.
Now, I need to figure out how to go about moving the tansaction logs off the current disk array and on to the new disk.
In Enterprise Manager, I brought up "Properties" for the first database, and went to the "Transaction Log" tab. Clicked on the "browse" or "..." button in the location field and got the following message:
"A transaction log file's physical name cannot be changed once the transaction log file has been created". :(

I have been looking through Books On Line, but have been unable to find anything helpful yet.

Can anyone help me figure out how to go about moving a transaction log's location? There has to be some way.
Even if it involves shutting down the server, altering system tables, etc. I need to get these moved.

Your help is appreciated. Thanks.

Help !!! None Of My Transaction Logs Are Getting Backed Up

Jan 19, 2001

Hi all,

I have set up a maintenance plan to backup my databases but when I view the maintenance plan history the transaction log backup steps have a success tick but a message saying :

"Backup can not be performed on this database. This sub task is ignored"

I have looked in my backup directory and only see *.BAK files and no *.TRN.
The transaction logs are supposed to back up at 1AM and the databases at 2AM

All my databases being backed up have the truncate log on checkpoint option set. Is this best practise according to my backup schedule ?

Help !!!!

Regards,

Tim

Aug 28, 2000

Hi all,

I am restoring database from Transaction Logs. I followed all the steps
mentioned in the book. Just before the last step there are three options
1. Leave Database Operational. No Additional Logs can be Restored.
2. Leave Database Nonoperational But Able to Restore Additional
Transaction Logs.
3. Leave Database Read_Only And Able To Restore Additional Transaction Logs.

Option 2 and 3 aresupposed to set on the NORECOVERY flag.

I tried both options 2, and 3 , But still got messages that I did not
specify WITH NORECOVERY or WITH STANDBY.

Can anyone please tell me what I am doing wrong?

Thanks in Advance.

Loading Transaction Logs.....

Aug 11, 1999

I have a MS SQL Server 6.5/SP5A database running on NT 4.0/SP4 Enterprise Edition with MS Cluster Server. On my Production box, I dump the transaction logs every 30 minutes. I need to recreate a point in time on a separate TEST box with the same hardware/software. I created a "DBA database" from a previous night of Production - no problem. However, when I start applying the transaction logs, it complains about being out of sequence. The timestamps that it is reporting are accurate for the transaction logs, but it is basically using the database load time to compare it with. (Granted I am moving from one box to another, but I didn't think this would be a problem). I created a "DBA database" on Production, went through the same steps, and it takes the database load and the transaction logs. I am assuming that the sequence numbers on the transaction logs are identified internally on the file, not per server? Ideas as to why it would complain on an out of sequence condition (Error 4305) when I move to a different box?

Multiple Transaction Logs

Nov 1, 2004

I have just come from an Oracle background and am trying to equate SQL server methodologies to Oracle. I have a couple of questions based on the same principle which is the usage of multiple transaction logs. This is what I have been able to find out from the docs and other posts:

If you have multiple transaction logs they will all be used in a sequential manner before being wrapped around. That is, they will all be filled before they are reused.

My first question is will they be used sequentially or concurrently. SQL Server seems to stripe everything so I am inclined to believe the latter. This question has been asked before but from other posts/docs there seems to be a difference of opinion. I am of course equating transaction logs to redo/archived logs so I want to know categorically (links would be greatly appreciated) as it will have a huge impact on any disaster and recovery plans that I implement.

The second question is a spin off and may or may not be relevant dependant on the answer of the first. If the transaction logs are written to concurrently, that is, entries are striped, why bother with multiple logs? I don't see any benefits. In fact, in a recovery scenario recovering transactions from mutliple striped logs would appear to adversely affect MTTR.

Feel free to point out the errors of my ways as I am all ears and eager to learn.

Thanks in advance.
