6 Scaling Out Oracle HTTP Server

The first Oracle HTTP Server was configured during the provisioning process (see Chapter 5). This chapter describes how to scale out Oracle HTTP Server for additional hosts.

This chapter includes the following topics:

6.1 Performing the Scaleout

To scale out Oracle HTTP Server:

  1. Reboot WEBHOST2 to start the scaleout from a clean machine.

    Note:

    WEBHOST2 and WEBHOST1 should be identical machines.

  2. Create the directory ORACLE_BASE/repository/installers with the same user that installed Oracle HTTP Server on WEBHOST1.

  3. Copy or ftp the installers from WEBHOST1 to WEBHOST2:

    WEBHOST1> ORACLE_BASE/repository/installers/webgate

    to

    WEBHOST2> ORACLE_BASE/repository/installers

    WEBHOST1> ORACLE_BASE/repository/installers/webtier

    to

    WEBHOST2> ORACLE_BASE/repository/installers

  4. Run the following command to install Oracle Web Tier on WEBHOST2 (oraInventory should be located in ORACLE_BASE/oraInventory):

    ORACLE_BASE/repository/installers/webtier/Disk1/runInstaller

    The Oracle Fusion Middleware 11g Oracle Web Tier Utilities Configuration Welcome window opens.

6.2 Performing WebGate Post-Installation Steps

After installing WebGate, do the following:

  1. Add LD_LIBRARY_PATH to ORACLE_BASE/products/webtier_mwhome/webtier/lib.

  2. Run the following commands:

    # Usage: deployWebGateInstance.sh -w <WebGate_instancedir> -oh WebGate_Oracle_Home

$  cd ORACLE_BASE/products/webtier_mwhome/webgate/webgate/ohs/tools/
deployWebGate

$ ./deployWebGateInstance.sh -w ORACLE_BASE/config/CommonDomain_
webtier1/config/OHS/ohs1 -oh ORACLE_BASE/products/webtier_mwhome/webgate

$  cd /ORACLE_BASE/products/webtier_mwhome/webgate/webgate/ohs/tools/setup/
InstallTools

$ ./EditHttpConf -w ORACLE_BASE/config/CommonDomain_webtier1/config/OHS/ohs1 
-oh ORACLE_BASE/products/webtier_mwhome/webgate -o webgate.conf

  3. Log in to your Oracle Access Manager server.

    Figure 6-23 Oracle Access Manager (2)

    Oracle Access Manager (2)

  6. From the OAM11gfilestab, shown in Figure 6-23, note the location of where the artifacts are generated on the IDMHOST machine. These artifacts should be copied to WEBHOST2.

    Figure 6-24 Oracle Access Manager (3)

    Oracle Access Manager (3)

  7. Copy the artifacts files from the IDMHOST machine to ORACLE_BASE/config/CommonDomain_webtier1/config/OHS/ohs1/webgate/config on WEBHOST2.

    Run the following commands from WEBHOST2:

    cd ORACLE_BASE/config/CommonDomain_webtier1/config/OHS/ohs1/webgate/config
$ cp  FROM OAMHOST ( location_of_artifacts)/ObAccessClient.xml .
$ cp  FROM OAMHOST ( location_of_artifacts)/cwallet.sso .
$ cp  FROM OAMHOST ( location_of_artifacts)/password.xml .
$ cd simple
$ cp  FROM OAMHOST ( location_of_artifacts)/aaa_key.pem .
$ cp  FROM OAMHOST ( location_of_artifacts)/aaa_cert.pem .

6.3 Installing WebGate Patches

If the ORACLE_BASE/repository/installers/webgate location has a patch directory, perform the steps in this section. If prompted, specify the JDK location.

To install WebGate patches, do the following:

  1. Change directory to ORACLE_BASE/repository/installers/webgate/patch/.

  2. If the directory under patch exists, set the path to the Opatch directory to ORACLE_BASE/products/webgate/OPatch.

    Note:

    Running the $ which opatch command will give you the path specified in Step 2.

  3. Install all the patches in ORACLE_BASE/repository/installers/webgate/patch/.

  4. Run the following command:

    ./opatch apply

    After you install the patches, restart the web server. Oracle HTTP Server scaleout is complete, and WEBHOST1 and WEBHOST2 should behave identically.

6.4 Wiring Oracle HTTP Server with Load Balancer

Configure your load balancer to route all HTTP requests to the hosts running Oracle HTTP Server, that is, WEBHOST1 and WEBHOST2.

You do not need to enable sticky session (insert cookie) on the load balancer when Oracle HTTP Server is the front end to Oracle WebLogic Server. You need sticky session if you are going directly from the load balancer to Oracle WebLogic Server, which is not the case in the topology described in this guide.

You also must set Monitors for HTTP.

6.5 Validating Oracle HTTP Server on WEBHOST2

To validate once the installation is complete:

  1. Check that it is possible to access the Oracle HTTP Server home page using the following URLs:

    • http://webhost1.mycompany.com:10601

    • http://webhost2.mycompany.com:7777

  2. Stop WEBHOST1:

    WEBHOST1> cd /u01/oracle/config/CommonDomain_webtier/bin

WEBHOST1> ./opmnctl stopall

  3. Access the following URLs to ensure that the Administration console is visible:

    • http://fininternal.mycompany.com:7777/console

    • http://hcminternal.mycompany.com:7777/console

    • http://scminternal.mycompany.com:7777/console

    • http://commoninternal.mycompany.com:7777/console

    • http://biinternal.mycompany.com:7777/console

    • http://prjinternal.mycompany.com:7777/console

    • http://prcinternal.mycompany.com:7777/console

  4. Access the following URLs to ensure that the Oracle Fusion Applications login screen is visible:

    • https://finexternal.mycompany.com/ledger/faces/LedgerWorkArea

    • https://finexternal.mycompany.com/payables/faces/PaymentLandingPage

    • https://prcexternal.mycompany.com/procurement/faces/PrcPoPurchasingWorkarea

    • https://prjexternal.mycompany.com/projectsFinancials/faces/PRJProjectWorkarea

    • https://commonexternal.mycompany.com/homePage/faces/AtkHomePageWelcome

    • https://biexternal.mycompany.com/analytics

  5. Run the following commands:

    WEBHOST1> cd /u01/oracle/config/CommonDomain_webtier/bin
 
WEBHOST1> ./opmnctl startall
