On a routine monitoring of the data files and transaction log, you notice that the transaction log is extremely close to being full. What will happen if the log fills? What steps can you take to avoid running out of transaction log space?

Posted By :Ravi Ranjan Kumar     Posted Date :July 24, 2011    Points :40   Category :Sql Server 
If the transaction log fills, you are unable to modify the data in the database until the log is archived or expanded. To avoid a full transaction log, you can monitor the log space regularly, expand the log whenever necessary, set the log to grow automatically, and create an alert to notify you when the available log space falls below a specified level (alerts are not covered in this training kit). Scheduling or performing frequent transaction log dumps is the best way to reclaim available space in the transaction log.

How can we cancel a transaction?


what are the content in Transaction log file backup?


Step 1 : Begin and End Transaction information

step 2 : Modified transaction information

step 3 : create or alter table information or index information (More...)

How does the Transaction topic work in asp ?

In Asp there is an Assembly called System.Transactions which contains classes that allows the applications to work under the transactions which were organized by
Microsoft Distributed Transaction Coordinator (MSDTC ) and
Local Transaction Manager(LTM ).

This System.Transactions assembly allows both implicit and explicit way of operation

The Explicit programming model is based on the Transaction class and
The Implicit programming model using the Transaction Scope class. (More...)

What advantage does a transaction have over a batch or script?

In short A transaction executes as a single unit of work. If a transaction fails, it can be rolled back as a unit, leaving data in a consistent state. (More...)

Database: What is recorded as transaction log for Truncate ?

Data page deallocation are recorded as transaction log for truncate command.


What is Transaction Propagation? And how WCF support it?

Transaction propagation is the ability to propagate transaction across the boundaries of a single service. Or in other words, we can say that a service can participate in a transaction that is initiated by a client.
In a SOA environment, transaction propagation becomes a key requirement. As we know that WCF supports SOA, so it provides support for transaction propagation as well.
To enable transaction propagation, we need to set the value of TransactionFlow property of the binding being used. This can be done programmatically as follows:
WSHttpBinding bindingBeingUsed = new WSHttpBinding();
bindingBeingUsed.TransactionFlow = "true";
Or It can be done declaratively by updating configuration file as follows:

transactionFlow="true" />

Default value for TransactionFlow property is "False".

Does all WCF bindings support for Transaction Propagation?

No. Not all WCF bindings support transaction propagation. Only following list of bindings support for it.
. wsHttpBinding
. netTcpBinding
. netNamedPipeBinding
. wsDualHttpBinding
. wsFederationHttpBinding

What are the various Transaction Flow Options available in WCF?

If a service is configured for Transaction Propagation, WCF further supports various options for service methods to be part of any transaction initiated outside service boundaries.
. NotAllowed Transaction Propagation is not allowed for particular service method. Its default value.
. Allowed Transaction Propagation is allowed but not compulsory.
. Mandatory Transaction Propagation is compulsory for that service method.
For example, Transaction Propagation is mandatory for CreditAccount service method in following code snippet.
interface IPaymentService
void CreditAccount(..);

What is the role of transaction manager in WCF?

Transaction manager while sitting on client side, initiate the transaction and coordinates with all the processes that participate in a distributed transaction to commit or roll back. (More...)

Explain the steps involved to populate dataset with data?

Open connection.;
Initialize Adapter passing SQL and connection as parameter.;
Initialize Dataset.;
Call Fill method of the adapter passes dataset as the parameter.;
Close connection.; (More...)

You are creating a database on multiple disks that will be queried intensively by users. What are some steps that you can take to improve performance and avoid disk contention?

You could use disk striping (RAID) to increase performance.

A secondary strategy would be to use filegroups to improve performance, especially placing the transaction log file(s) on a separate disk from the data file(s) to avoid disk contention as SQL Server queries the database and records actions in the log. Also, filegroups could be used to separate a portion of the data files requiring frequent backups because they are actively modified.
