Commerce Server 2007
For the latest version of Commerce Server 2007 Help, see the Microsoft Web site.

The pipeline specified by a .pcf file is created and run by a pipeline object. Commerce Server provides six objects to run pipelines that are shown in the following table.

Only the MtsTxPipeline Object and the PooledTxPipeline Object pipelines support transactions.

The MtsTxPipeline Object pipeline is recommended only for development.

Non-pooled pipeline objects are useful when you are development and debugging pipelines because they do not require that you execute an IISReset command to take effect.
