TIBCO iProcess® Engine 11.10.0

# EAI_NEEDS_MSDTC

General iProcess Engine Configuration

Note: This attribute is only relevant to the Windows version of iProcess Engine. It does not affect the UNIX version.

## Summary

This attribute defines the EAI server plug-ins that need to use the Microsoft Distributed Transaction Coordinator (MSDTC).

## Applies To

The attribute can be set for the `BG`, `BGPRDICT`, and `RPCBG` processes.

## Permissible Values

The attribute value must be a comma-delimited list of EAI step names. The name used should be the same name used to register the EAI server plug-in.

## Default Value

The attribute is assigned the following default values when the iProcess Engine node is installed.

Machine ID | Process | Instance | Value
0 | BG | 0 | EAICOM
0 | BGPREDICT | 0 | EAICOM
0 | RPCBG | 0 | EAICOM

## Notes

You should set this attribute for any EAI server plug-ins that you develop that require the use of the MSDTC. If you don’t do so, EAI steps using the plug-in may not function correctly or in a fully transactional manner.

Note: Currently, the only TIBCO iProcess server plug-in that requires the use of the MSDTC is the TIBCO iProcess COM Server Plug-in. The default value for this attribute is therefore set to EAICOM.

When a `BG` process loads an EAI server plug-in, it will check to see if the plug-in’s name is specified in the `EAI_NEEDS_MSDTC` value. If it is, it turns on the use of the MSDTC. For more information about:

| • | the MSDTC, see “What is MSDTC” in TIBCO iProcess Engine Architecture Guide.

| • | EAI server plug-ins, see Managing EAI Step Server Plug-ins, and “Using Enterprise Application Integration (EAI) Steps” in TIBCO iProcess Modeler Integration Techniques.

| • | the EAI COM server plug-in, see TIBCO iProcess COM Plug-in User’s Guide.
