This is my quick reference for single-server TIBCO BPM iProcess engine installation on Solaris. Possible to add another server and convert environment to a cluster later. Oracle has to be installed, ORACLE_HOME and ORACLE_SID environment variables must be set. Run swinstall installation script as a root user who also DBA in Oracle, script will create iProcess database.

./swinstall

Script will collect installation data:
Installing TIBCO iProcess Engine version 11.0.2

TIBCO iProcess Engine Installation Complete

Display engine password:
TIBCO iProcess Engine Password is:
********************************************
* 3BFD-7292-DBAF-A3E7-823D-4720-351E *
********************************************
Licensee Name is:
TIBCO iPE 11.0.2 Install
(The existing TIBCO iProcess Engine Password and Licensee Name may also be
displayed later by running 'swconfig').

Reminder:
All users of TIBCO iProcess Engine (Staffware) should have the
environment variable $SWDIR set to
/export/home/tibco/tibco/iprocess
before invoking or starting TIBCO iProcess Engine.

Installer will run the final check and complete:
TIBCO iProcess Engine Nodename ( s-bpm01 ) checked OK.
TIBCO iProcess Engine RPC Number ( 391875 ) checked OK.
TIBCO iProcess Engine service ports checked OK
TIBCO iProcess Engine process entries OK

Then I have to create this .profile for pro user:
SWDIR=/export/home/tibco/tibco/iprocess
export SWDIR
ORACLE_HOME=/export/home/oracle/product/10.2.0/db_1
ORACLE_SID=orcl
export ORACLE_HOME ORACLE_SID
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ORACLE_HOME/lib:$SWDIR/libs
export LD_LIBRARY_PATH

To start iProcess engine:
su - pro
cd bin
./swstart -p
./swstart

Admin tool:
su - pro
cd util
./swadm
