TIBCO iProcess® Engine 11.9.1

# Windows Version

In the Windows version, the iProcess Engine functions are provided by the iProcess `nodename` Process Sentinels service (where `nodename` is the name of your iProcess Engine installation).

By default, after having been started, Process Sentinel tests the event mechanism automatically and starts the iProcess Engine server auto-start processes.

Note: This behavior is controlled by the PM_AUTO_BOOT process attribute, only the value of the `PM_AUTO_BOOT` attribute is set to `1`, the processes will be started automatically. See Administering Process Attributes for more information.

You can start the Process Sentinels service in three different ways (unless you have installed iProcess Engine to a Windows cluster):

| • | At system startup - see An operating system group that gives you permissions to start a service, normally the Administrators group..

| • | Manually, from the Windows Control Panel - see Manually Starting the Process Sentinels Service.

| • | Using the swstart.bat script located in the SWDIR`\bin` directory- see Using the swstart.bat Script.

To be able to start iProcess Engine, you must be logged in as an iProcess Engine Administrator or as a user who is a member of both:

| • | The iProcess Administrators local group (which gives you permissions on files and directories in SWDIR).

| • | An operating system group that gives you permissions to start a service, normally the Administrators group.

Warning: If you have installed iProcess Engine to a Windows cluster, use the Bring online service in the Microsoft Cluster Administrator to start iProcess Engine.

Do not attempt to start iProcess Engine on a Windows cluster by using Control Panel > Services or the `swstart` command located in the SWDIR`\bin` directory.

## Configuring System Startup Behavior

When you install iProcess Engine, you choose whether or not the Process Sentinels service:

| • | Starts automatically on system startup (the default option).

| • | Needs to be started manually.

| • | Is disabled (cannot be started).

If you subsequently want to change this setting, do the following:

| 1. | From the Start menu, select Settings > Control Panel.

| 2. | Double-click the Administration Tools item.

| 3. | Double-click the Services item. The Services dialog box appears.

| 4. | Select the iProcess Nodename Process Sentinels service item (where `Nodename` is the name of your iProcess Engine installation) and click the Startup button. The Service dialog box appears.

| 5. | Set the Startup Type item to:

| — | Automatic, if you want the Process Sentinels service to start automatically on system startup.

| — | Manual, if you want to manually start the Process Sentinels service (see the following).

| — | Disabled, if you want to disable the Process Sentinels service.

Note: Do not change any other options in the Service dialog box. Doing so might cause iProcess Engine to fail.

## Manually Starting the Process Sentinels Service

To manually start the Process Sentinels service:

1. From the Start menu, select Settings > Control Panel.

2. Double-click the Administration Tools item.

3. Double-click the Services item. The Services dialog box appears.

4. Select the iProcess Nodename Process Sentinels service item (where `Nodename` is the name of your iProcess Engine installation).

5. Click the Start button. This will start the Process Sentinels service and the iProcess Engine server processes.

   Note: You can use the Processes tab of the Windows Task Manager to view the processes as they start. See Server Processes for a list of processes that are started.

## Using the swstart.bat Script

To start the Process Sentinels service using the `swstart.bat` script located in the SWDIR`\bin` directory:

1. Start the Process Sentinels by using the following command:

   `swstart -p`

2. Start the iProcess Engine server processes by following one of the two ways:

   - normally, by using the `swstart` command

   - in quick start mode, by using the `swstart -q` command

Note: When the iProcess Engine server is restarted or quick started, the iProcess Objects Server processes apply the `RESTART_SPO_CACHE_PROC` attribute to cache a specified number of procedure versions and the `WIS` processes apply the `RESTART_WIS_CACHE_THRESHOLD` attribute to cache the work queues at a specified work item number. For more information, see RESTART_WIS_CACHE_THRESHOLD and RESTART_SPO_CACHE_PROC.
