TIBCO iProcess® Engine 11.9.1

# Setting Up the Shared Library Path for the iProcess Engine

## Status

If you are... | This task is...
Installing a new iProcess Engine | Required
Upgrading from an iProcess Engine 11.1 or later | Required

## Database

Oracle, DB2

## Description

To allow the iProcess Engine to operate correctly, the shared library path environment variable must be correctly set up for the following UNIX users:

| • | All users who want to use iProcess Engine administration utilities such as `$SWDIR``/util/swadm`.

| • | The iProcess Engine background user, to allow the `BG` process to start and function correctly.

You can check the current value of the shared library path variable using the commands listed in The Commands To Check The Shared Library Path.

The Commands To Check The Shared Library Path

Database | Platform | Command
Oracle, DB2 | Linux | `echo $LD_LIBRARY_PATH`

## Procedure

Make sure that the strings listed in The Included String in the Shared Library Path Variable are included in the shared library path variable for each user that needs it.

The Included String in the Shared Library Path Variable

Database | Command
Oracle | `$ORACLE_HOME``/lib:``$SWDIR``/libs`
DB2 | `/usr/lib/64:``$SWDIR``/libs` You must also ensure that the `libdb2` library is in a standard directory, such as `/usr/lib/64`. When you use the `$SWDIR/bin/swstart -p` command to start iProcess Engine, the `RPC_UDP_LI` process fails to start up if it cannot find the `libdb2` library in a standard directory, such as `/usr/lib/64`. This is because it is a SUID process, and therefore ignores the `LD_LIBRARY_PATH` environment variable.
