    Oracle Apps Load Balancer Setup for HTTP Server
    Wednesday, December 20, 2006
    Register for R12 upgrade

    I am going to cover most common load balancer setup in Oracle Apps 11i i.e. Setup Two or more Middle tier with Web Server & Form Server with Hardware Load balancer in front of middle tier . This type of setup is also called as "HTTP Layer Hardware Load balancing" in Oracle Applications.
    For overview & basics of Load balancing visit my previous post at

    http://becomeappsdba.blogspot.com/2006/09/configure-load-balancer-in-oracle-apps.html

    http://becomeappsdba.blogspot.com/2006/09/configure-hardware-load-balancer-at.html

    Below are steps you need to follow to configure Multiple Middle Tier (Web & Forms Server ) with Hardware Load balancer in front.
    1. Setup a Load balancer such that it forwards requests to first middle tier only.
    2. Make sure sticky bit is set on load balancer for session persistence (Check Load balancer documentation), You can Network level switch as well to send requests to multiple middle tier
    3. Apply Prereq. patches (3175852, 3077386, 3209878)
    4. Edit following entry in XML or Context File directly ($APPL_TOP/admin/$CONTEXT_NAME.xml) or via Oracle Application Manager
    -- 4.1 "Web entry point Host" to the HTTP load-balancer machine name
    -- 4.2 "Web entry point Domain" to the HTTP load-balancer domain name
    -- 4.3 "Web entry protocol" to the HTTP load-balancer protocol e.g. "http" or "https"
    -- 4.4 "Active Web Port" to the value of the HTTP load-balancer's external port
    -- 4.5 "Login Page" to include "Web entry protocol"://"Web Host entry point"."Web domain entry point":"Active Web Port"
    -- 4.6 "disco_machine" to load balancer machine
    5. Run Autoconfig
    6. Start Services & check if you can login to applications via Load balancer
    7. Now clone this middle tier to another node (where you want to add another node)
    8. Make sure above parameter are pointing to load balancer in second node as well
    9. Change load balancer to point to second node only
    10. shutdown services on first node
    11. try accessing application from second node (you should be able to access application without issues)
    11.1 -- If forms are not opening properly , check "ICX Form Launcher .." Profile option should point to load balancer
    12. Now start application on both middle tier
    13. Point load balancer to both middle tier
    14. You should be able to access applications
    Things to Note :
    ------------------
    Above solution is for HTTP Layer load balancing & HTTP Server will forward Forms request to form server running on same node .

    Oracle Web Cache
    Monday, December 18, 2006
    Register for R12 upgrade
    What is Oracle Web Cache ?
    Oracle web cache is component of 10g Application Server which is installed by default with Portal & Wireless or BI & Forms type Installation. You can also install standalone webcache for J2ee & webcache applications or to configure webcache with Oracle Applications 11i.

    Why I need Web Cache ?
    As name suggest web cache act as Cache for Web Servers including Oracle Application Server 9i, 10g to cache frequently used static & dynamic pages. Web Cache is used for increasing response time of your site by caching frequently used partial / full page , images, pdf. Web cache can also act as Software Load balancer or Reverse Proxy Server or Front end to your Applications to Hide server name.

    Is Web Cache configurable & Certified with Apps 11i ?
    Yes, Web cache can be configured with Apps 11i as reverse proxy server (for security) and Failover & Surge Protection (To minimize downtime) .
    *Web Cache can't be used as Load balancer for E-Business Suite as its not possible to set session stickyness in Webcache. (Thanks to Gaurav for pointing this out)

    Check Metalink Note 306653.1 Installing and Configuring Web Cache 10.1.2 and Oracle E-Business Suite 11i

    How to start / stop webcache ?
    To start/stop webcache with 10g AS, use
    opmnctl startprocstopproc ias-component=WebCache
    For standalone J2ee & Webcache Installation use
    webcachectl startstop

    How to troubleshoot Webcache Issues ?
    Webcache logs are at $ORACLE_HOME/logs event_logs & access_log , all issues errors are recorded in event_logs so check this file any issues related to Webcache .

    Sunday, December 17, 2006
    Register for R12 upgrade
    Last week I discussed about certification track for apps dba One of them was for 10g Application Server or Fusion Middleware 1Z0-311 which I cleared last month.

    Books I followed
    I prepared from OCA Oracle Application Server 10g Administrator: Exam Guide Exam 1Z0-311 (Osborne Oracle Press) written by Sam Alapati.

    This book covers exam objectives & questions at end of each topic.You will also get two mock test out of which 30-40% questions you can see in real exam.

    If you are new to 10g Application Server, I found this book on Amazon Oracle Application Server 10g Administration Handbook (Oracle Press)

    So if you have hands on experience on 9iAS or 10g Application, Try for this certification.

    oraInventory in Oracle
    Thursday, December 14, 2006
    Register for R12 upgrade
    You all might be familiar with oraInventory & its importance so lets take a look at few common things about it like binary/xml inventory, What to do if Inventory is corrupted , What is global / Local Inventory and where to find documentation related to oraInventory .

    What is oraInventory ?
    oraInventory is repository (directory) which store/records oracle software products & their oracle_homes location on a machine. This Inventory now a days in XML format and called as XML Inventory where as in past it used to be in binary format & called as binary Inventory.
    There are basically two kind of Inventory Global Inventory (also called as Central Inventory) and Local Inventory also called as Oracle Home Inventory.

    Global Inventory ?
    Global Inventory holds information about Oracle Products on a Machine. These products can be various oracle components like database, oracle application server, collaboration suite, soa suite, forms & reports or discoverer server . This global Inventory location will be determined by file oraInst.loc in /etc (on Linux) or /var/opt/oracle (solaris). If you want to see list of oracle products on machine check for file inventory.xml under ContentsXML in oraInventory (Please note if you have multiple global Inventory on machine check all oraInventory directories)

    You will see entry like
    HOME NAME="ORA10g_HOME" LOC="/u01/oracle/10.2.0/db" TYPE="O" IDX="1"/
    ...
    ...

    Local Inventory
    Inventory inside each Oracle Home is called as local Inventory or oracle_home Inventory. This Inventory holds information to that oracle_home only.

    Can I have multiple Global Inventory on a machine ?
    Quite common questions is that can you have multiple global Inventory and answer is YES you can have multiple global Inventory but if your upgrading or applying patch then change Inventory Pointer oraInst.loc to respective location. If you are following single global Inventory and if you wish to uninstall any software then remove it from Global Inventory as well.

    What to do if my Global Inventory is corrupted ?
    No need to worry if your global Inventory is corrupted, you can recreate global Inventory on machine using Universal Installer and attach already Installed oracle home by option
    -attachHome

    ./runInstaller -silent -attachHome -invPtrLoc $location_to_oraInst.loc
    ORACLE_HOME="Oracle_Home_Location" ORACLE_HOME_NAME="Oracle_Home_Name"
    CLUSTER_NODES="{}"

    Do I need to worry about oraInventory during oracle Apps 11i cloning ?
    No, Rapid Clone will update both Global & Local Inventory with required information , you don't have to worry about Inventory during Oracle Apps 11i cloning.

    Oracle Internet Directory , OID Troubleshooting
    Saturday, December 09, 2006
    Register for R12 upgrade
    OID in 10g Application Server (Standalone or with Apps) is quite important so today I am going to discuss how you should troubleshoot OID and related Issues .

    How to Check if OID is UP ?
    First check if OID/Oracle Internet Directory is Up or now. Following are few ways you can confirm if OID is up or not.

    Method 1 :
    opmnctl status (Execute it at Infra Oracle_HOME)
    You should see output like

    Processes in Instance: INFRA01.teachmeoracle.com
    -------------------+--------------------+---------+---------
    ias-component process-type pid status
    -------------------+--------------------+---------+---------
    OID OID 2355 Alive

    Which means OID is up (Please note sometime if OID ports are not binded you will still see OID up but no OID ldap process. This is because opmn monitors/starts only oidmon - OID monitor process which in turn starts oid ldap process so opmn is not aware that oidmon was not able to start oid ldap server)

    Method 2
    Check if OID ports are listening or not
    OID by default starts on both SSL (636) & Non SSL port (389) so check it with unix command netstat like
    $ netstat -an grep 636 more
    $ netstat -an grep 389 more

    Troubleshoot OID
    If you see OID process are not running then try to start OID , steps are
    1. Make sure OID database & listener are up & running , If not start them . Sometime it happens that there might be more than 1 database in your system (one for E-Business, one for portal, one for disco and one for OID/Infra MR) and if you wish to find which database is used by OID--
    open opmn.xml in ORACLE_HOME/opmn/conf

    category id="oidmon-parameters"
    data id="connect" value="INFRA"/
    data id="host" value="teachmeoracle.com"/
    data id="run-oidctl" value="true"/
    Which means OID database is on machine teachmeoracle.com & connect value is INFRA

    2. After starting database you can try starting OID via opmn like
    opmnctl startproc ias-component=OID or
    opmnctl startall

    Check for any error messages in $ORACLE_HOME/ldap/log
    oidmon.log - OID monitor process log file
    oidldapdXXXX.log - OID Ldapd server process log file
    odisrvXXX.log - OID Integration & Provisioning Server log file

    Check for error message in Metalink

    If you see any error message in above log file & don't understand feel free to leave comment on this blog.

    Oracle Internet Directory OID
    Monday, December 04, 2006
    Register for R12 upgrade
    OID which stands for Oracle Internet Directory is part of Identity Management in Infrastructure Tier of Fusion Middleware. If you are planning to configure 10g Application Server with Apps 11i or R12 , This node might be useful for you in understanding OID . Looking at importance of OID, I am going to discuss on few important things about OID today .
    OID is installed on infrastructure tier in 10g Application Server (If you want to learn basic components of Application Server you can visit my previous post at http://becomeappsdba.blogspot.com/2006/10/fusion-middleware-10g-application.html )

    what's is OID ?
    Oracle Internet Directory (OID) is Oracle's Implementation of LDAP (Light weight Directory Access Protocol) which is ldap version 3 compliant. OID is special kind of database repository in which information is stored in Tree structure also called DIT (Directory Information Tree).
    Similar to OID , Microsoft has its own LDAP server called Active Directory (AD) and Sun's LDAP server is called as iPlanet .

    Where is OID code in oracle_home ?
    OID code & its corresponding log files are stored in directories under $ORACLE_HOME/ldap directory in Infrastructure Tier . This is same tier where your SSO server sits.
    OID logs are stored at $ORACLE_HOME/ldap/log (This location is quite important for apps dba's for troubleshooting OID Issues). Few executables like oidctl, oidadmin, oidca, oidldapd are in ORACLE_HOME/bin .

    What are default ports for OID ?
    You may see different ports for OID depending on OID server version but most common is 389 non ssl OID port & 636 for SSL OID port (These are also default ldap server ports). If you don't know which ports your OID is using refer portlist.ini in $ORACLE_HOME/install (Note that this file will not list updated port if you change OID ports after Installation)
    You should an entry like
    Oracle Internet Directory port = 389
    Oracle Internet Directory (SSL) port = 636

    How to start OID ?
    OID process is controlled by opmn (Oracle process monitor & notification server) so you by default use opmnctl command
    To Start OID opmnctl startproc ias-component=OID
    To Stop OID opmnctl stopproc ias-component=OID

    OID can also be started without OPMN by
    First start oidmon (OID Monitor Process)
    Then use oidctl (OID control)
    To stop OID without OPMN

    Application Server Guard, Disaster Recovery for Oracle Application Server
    Sunday, December 03, 2006
    Register for R12 upgrade
    Application Server Guard is Next level of Disaster Recovery Solution by Oracle (Currently only for Application Server/ Fusion Middleware). Application Server Guard (with underlying dataguard for database) incorporate Middle Tier configuration recovery on standby site.
    Lets discover overview & main component of AS Guard ( ASG , also called as DSA Distributed Server Architecture).

    Components of AS Guard
    Application Server Guard also called as AS Guard is automatically Installed with 10g Application Server . Real features/advantages of AS Guard started with version 10.1.2.0.2 and bugs associated in this release with some more features are fixed in Version 10.1.2.2.0 . AS Guard binaries are Installed under folder "DSA" under oracle_home . If you have standalone database , you can install standalone AS Guard under database oracle_home. Software is available at http://www.oracle.com/technology/software/products/ias/htdocs/101202.html

    AS Guard consist of Server & client (any ASGuard with asgctl.sh can act as Client).

    For database it uses dataguard (You don't have to configured dataguard for database AS Guard will configure it for you if your database was part of Application Server Installation) If your database is created by MRCA/Repca (Metadata Repository Creation Assistance Tool) then you have to configure Dataguard at your own.

    For Identity Management & Middle tier configuration it uses backup & recovery tool in Application Server (This is automated by AS Guard, you don't have to do anything)

    Primary & Standby Site
    Primary & Standby site can be synchronous (Same number of nodes in standby as primary) or asynchronous (Number of nodes in standby are less as compared to primary-Like primary site is with two middle tier and one infra tier where as standby site with only one middle tier & one infra tier- P.S. standby site should have at least one middle tier & one infrastructure tier)

    Start/Stop AS Guard Server
    If AS Guard Server is part of application Server you start it using opmnctl like
    opmnctl startproc ias-component=DSA
    For standalone AS Guard you use dsaServer.sh under oracle_home/dsa/bin like
    nohup dsaServer.sh &

    Operations in AS Guard

    instantiate -
    This is process of building primary & standby relationship and done only once. In this step AS Guard will create standby database for Application Server metadata repository database , backup configuration files from primary site & restore them to standby site

    sync-
    This is method of synching standby site with primary site. In this step standby database is synched with primary database . Configuration files from IM node & middle tier node on primary site are backed up & restored in standby site

    switchover-
    This is the process of converting role of primary in to standby & standby into primary. Useful in situation like server maintenance in primary site or any activity on primary site so that standby site can be used as primary site

    failover-
    This is the process of converting standby site as primary (same as above except here primary site is not converted as standby). Useful in situation if primary site is not available because of some reason.

    For using AS Guard (Application Server Guard) as Disaster Recovery solution , you have to select HA (High Availability) & then Virtual Host during IM Installation.

    More on AS Guard configuration coming soon....

    If you are facing any issue in AS Guard configuration drop a mail at atul_iiit@yahoo.com with your Issues or you can raise your doubt at http://TeachMeOracle.com/forum
