# Starting TIBCO iProcess Engine

## Status

If you are... | This task is...
Installing a new iProcess Engine Version 11.8.0 | Optional
Upgrading from an iProcess Engine Version 11.0 or later | Optional

## Database

Oracle, DB2

## Description

The iProcess Engine is now properly installed, configured, and ready to start up.

## Node Cluster

Install each node in the cluster before trying to start the iProcess Engine.

## Procedure

To start the iProcess Engine:

Note | When you install iProcess Engine with the Oracle database 11g, if the Oracle server and client have been installed on an x86 platform and a non-x86 platform respectively, you must run the following steps before starting iProcess Engine:
| 1. | Log in to SQLPlus using the system account.
| 2. | Run the following statement:
`alter system set events='10867 trace name context forever, level 1';`

1. Log in as the iProcess Engine `background` user

2. Enter the following command to start the process sentinels:

`$SWDIR``/bin/swstart -p`

| — | If you selected Enable Autostart on the Configuration Options Menu, the process sentinels automatically start all of the iProcess Engine processes.

| — | If you did not select Enable Autostart on the Configuration Options Menu, enter the following command to start the iProcess Engine processes

`$SWDIR``/bin/swstart`

## Quick Starting and Restarting iProcess Engine

You can also use the following command to quick start the iProcess Engine processes:

```` `SWDIR```/bin/swstart -q``

You can use the `RESTART_SPO_CACHE_PROC` process attribute to define how many latest versions of procedure definition to be cached by the `iProcess Objects Server` processes when restarting the `iProcess Objects Server` processes or quick starting iProcess Engine; use the `RESTART_WIS_CACHE_THRESHOLD` process attribute to define the threshold number of work items in a work queue to be cached by the `WIS` processes when restarting the `WIS` processes or quick starting iProcess Engine.

For more information about the `swstart -q` command, see "Controlling the iProcess Engine" in TIBCO iProcess Engine Administrator's Guide. For more information about the `RESTART_SPO_CACHE_PROC` and `RESTART_WIS_CACHE_THRESHOLD` process attributes, see "Administering Process Attributes" in TIBCO iProcess Engine Administrator's Guide.
