Silent Installation and Configuration of Standalone Oracle HTTP Server

Currently I am working in a project for which will be needed the Oracle HTTP Server (OHS) in a Standalone Mode as a frontend Web Server for a Oracle SOA 12.2.1.2.0 environment.

As I am not really a fan of clicking through several installers and configuration wizards, I have created some scripts for a complete silent installation of the Standalone Oracle HTTP Server 12.2.1.2.0 and on top a silent configuration of the standalone Domain for the Oracle HTTP Server.

Silent Installation of the Oracle HTTP Server Software

For the following example, we will use following naming convention:

• MW_HOME=/u00/app/oracle/product/fmw-webtier-12.2.1.2.0
• JAVA_HOME=/u00/app/oracle/product/jdk1.8.0_121
• DOMAIN_HOME=/u00/app/oracle/user_projects/domains/ohs_domain

Download at first the required installation software from Oracle Technology Network http://www.oracle.com/technetwork/middleware/webtier/downloads/index.html and transfer the installation software to your target server, e.g. /u00/app/oracle/tmp.

Make sure you that you have a JDK 1.8 on your server, I prefer to install the JDK under the Oracle user, e.g. /u00/app/oracle/product/jdk1.8.0_121

Connect to your server as oracle user and create following files under the directory /u00/app/oracle/tmp

webtier.rsp

[ENGINE]
Response File Version=1.0.0.0.0
[GENERIC]
ORACLE_HOME=/u00/app/oracle/product/fmw-webtier-12.2.1.2.0
INSTALL_TYPE=Standalone HTTP Server (Managed independently of WebLogic server)
DECLINE_SECURITY_UPDATES=true
SECURITY_UPDATES_VIA_MYORACLESUPPORT=false

oraInst.loc

inst_group=oinstall
inventory_loc=/u00/app/oracle/oraInventory

Now we can extract the installation software and install the Oracle HTTP Server in silent mode

oracle@server> cd /u00/app/oracle/tmp
oracle@server> unzip fmw_12.2.1.2.0_ohs_linux64_Disk1_1of1.zip
oracle@server> ./fmw_12.2.1.2.0_ohs_linux64.bin -jreLoc /u00/app/oracle/product/jdk1.8.0_121 -silent -responseFile /u00/app/oracle/tmp/webtier.rsp -invPtrLoc /u00/app/oracle/tmp/oraInst.loc

The installation of Oracle HTTP Server 12.2.1.2.0 completed successfully.
Logs successfully copied to /u00/app/oracle/oraInventory/logs.

Now we have installed the Oracle HTTP Server Software.

Silent Configuration of the Standalone Domain for the Oracle HTTP Server

The next step is to configure in a silent way the required Standalone Domain for our Oracle HTTP Server.

For this I have 3 scripts:

• setLocalEnv.sh = contains all necessary Environment Variables for the creation of the Standalone Domain
• cr_ohs_domain.sh = Wrapper Script to source the setLocalEnv.sh and execute the cr_ohs_domain.py
• cr_ohs_domain.py = Python Script to create the Standalone Domain for the Oracle HTTP Server

setLocalEnv.sh

export NM_HOME=$DOMAIN_HOME/nodemanager
export OHSINSTANCENAME=ohs1
export OHSADMINPORT=9999
export OHSHTTPPORT=7777
export OHSHTTPSPORT=4443

The above Environment Variables are all self-explained, you may align them to your specific needs.

Switching MPM Type for Oracle HTTP Server 12c

The Oracle HTTP Server (OHS) comes by default with the MPM (Multi-Processing Modules) Type event for Linux systems, but sometimes you need to change the MPM Type for example to prefork.

The Oracle HTTP Server comes by default with 4 MPM Types:

• Worker: This is the default for non-Linux UNIX Platforms, e.g. Solaris, AIX ...
• Event: This is the default for Linux Platforms
• Prefork: This Type implements a non-threaded, pre-forking server, that handles request as an Apache HTTPD Server 1.3
• WinNT: This is the default for Windows Platforms

For more details about the MPM Types see http://docs.oracle.com/middleware/12212/webtier/administer-ohs/man_server.htm#zzaszzohszzmpm

In case you need to switch the MPM Type, you need at first to check if you have a standalone OHS or a OHS in a WebLogic Server Domain, as the way to switch the MPM Type is depending on these 2 options.

Switching MPM for a standalone OHS:

Simply connect to your server as oracle user and perform following steps:

cd $DOMAIN_HOME/config/fmwconfig/components/OHS/<OHS_Componentname>/

# Open the Config File ohs.plugins.nodemanager.properties
# and add following line at the end
# depending on your desired MPM Type
# mpm = prefork
# mpm = worker
# mpm = event
mpm = prefork

After that restart your OHS with:

cd $DOMAIN_HOME/bin
./stopComponent.sh <OHS_Componentname>
./startComponent.sh <OHS_Componentname> 

Switching MPM for OHS in a WebLogic Domain

Simply connect to your server as oracle user and perform following steps:

$ORACLE_HOME/oracle_common/common/bin/wlst.sh
connect('weblogic', '<AdminPassword>', '<servername>:<Port>')
editCustom()
cd('oracle.ohs')
cd('oracle.ohs:type=OHSInstance.NMProp,OHSInstance=<OHS_Componentname>,component=OHS')
startEdit()
# Set here your desired MPM Type

# possible values are:

# - prefork

# - event

# - worker

# - winnt (only for Windows)
set('Mpm','prefork') 
save()
activate()

After that restart your OHS with:

cd $DOMAIN_HOME/bin
./stopComponent.sh <OHS_Componentname>
./startComponent.sh <OHS_Componentname>
